The dynamic behaviors of changeable mechanical system are simulated by applying decentralized motion control schema to mechanical system problems. The schema models a motion control system as a set of simple mass control sub-systems to take control of each joint. Sub-systems that are a sort of an agent exchange the information of joint motion each other to control joint corresponding to its-self. The motion of mechanical system is tailored by the independent action of sub-systems to be done with information exchange. Phase plane analysis is conceived as a simple method for realizing the mass control of each joint and it is applied for decentralized mechanical system position control system base on the modeling. Numerical simulations are executed for investigating the feasibilities and the influences of the decentralized mass control base on phase plane analysis. The correlation by each agents was considered from the behavior in different postures and situations.

The flying creatures which have wings, such as the bird and part of the insects, take the complex motions. For example, the eagle circles over the upper air with no wing motion, and the bee has wings moving very quickly to hover over the flower. The purpose of our research is to analyze these complex motions of the flying creatures through the computer simulation. To simulate the motion of creatures we use the virtual environment. It consists of the physical engine library, which processes the motion and collision of rigid bodies, and the drag force expressing the force from a fluid. The creatures receive the sensor signals from the environment and output the torques to move their bodies according to the signals. We use the artificial neural network (ANN) as the controller converting the input into the output. Changing the weights of ANN using the real coded genetic algorithm, we evolve the creatures to acquire the complex behavior.

Ball-end mills are useful cutters for machining a three dimensional shape. Therefore, it is very important to estimate the machining error caused by deflection of ball-end mill in cutting process. The purpose of this study is a real-time compensation of the machining error caused by deflection of end mill at a cutting point. For this final purpose, in this research, relationship between deflections of tool estimated from cutting forces and measured deflections of tool in ball-end milling of hemisphere surface was investigated experimentally. As a result, it was found in the experiments that machining errors in ball-end milling could be estimated from normal force at the moment when radial direction of peripheral cutting edge is normal to the feed direction of tool.

Chatter vibrations decrease machining accuracy and production efficiency in end-milling. The purpose of this study is to obtain a method of fast detection of chatter in end-milling expected in high speed milling. For this purpose, the correlation function is introduced to the present method because calculation time for correlation function is expected to be shorter than the FFT. As a result of calculations, it was concluded that detection accuracy by using correlation function was approximately equal to the FFT method, and algorithm for detection of chatter was easier than the FFT method because the threshold value required in the present method can be determined more simply than the FFT method.

In this study, a method for optimizing feed rate based on cutting force in drilling processes is proposed in order to cut glasses which are one of brittle materials under suitable cutting conditions at all times. A system which can control at constant cutting force by changing feed rate based on cutting force signal of feed direction measured by a piezoelectric dynamometer was developed. Cutting tests with the developed system were carried out using coated carbide drills with a diameter of 1 mm under various cutting conditions and then cutting surfaces were observed. As the results, the cutting surfaces are fine roughness generated by ductile cutting under specific conditions. From the results, it is confirmed that the proposed method can drill glass under suitable cutting conditions.

Acoustic emission (AE) is the elastic stress wave caused by the deformation and fracture of a material. By measuring the AE signals with an AE sensor, it is possible to perform the in-process monitoring of machining state. In this study, AE signals generated in cutting experiments and wear experiments were measured in order to examine the relationship between AE signals and cutting phenomena. This paper discusses the characteristics of AE signals (e.g. amplitude and AE frequency) and the relationships between the phenomena and the AE signals obtained under each phenomenon. Moreover, the relationship with the AE signals measured during actual machining process is described.

The heat generated in the cutting process raises the temperatures of the tool, work, machine tool and so on, and causes many troubles such as the tool wear-out and damage. In this study, a technique with the infrared camera was proposed for the monitoring of machining state, in which the temperature of the cutting tool and the cutting force were measured when cutting conditions are changed. The measured results of temperature were compared with the results of cutting force simultaneously measured. As a result, it was clarified that the temperature of the tool showed same change as the cutting force.

The hard X-ray telescope which will be loaded into the next generation international X-ray astronomical satellite ASTRO-H, to be launched in 2014, consists of 1,278 sheets of Pt/C multilayer-coated thin foil mirrors which are as thin as 0.2 mm in thickness. Those thin foil mirrors are arranged with high density between an inner and outer cylinder inside the hard X-ray telescope housing in order to reflect X-ray accurately and make X-ray images on the focal plane. Therefore high assembly accuracy for the hard X-ray telescope housing, especially the inner cylinder which fixes those thin foil mirrors, is required. In this research, ultra-precision shape measurement of the hard X-ray telescope housing with a large ultra-precision diamond turning machine and laser displacement sensor is considered.

Interferometry is widely used in nanometer profile measurement of flat and spherical surface. However, it is difficult to measure aspheric surface using interferometers, because it is impossible to make a large reference surface with nanometer accuracy. Scanning defletometry based on ESAD (Extended Shear Angle Difference) is used to measure ultra-precise large near-flat and slight curved optical surface with the accuracy of sub-nanometer. However, it is not possible for it to measure aspheric surface because of the limitation of the measuring range of autocollimators. To make this method feasible to measure large aspheric optical surface, we proposed a new measuring method using autocollimator with rotatable optical devices fixed on linear motion stage. To eliminate the influence of the pitching error of the scanning stage, we made the rotatable optical devices have the same effect with a pentaprism. The simulation of the error analysis of the method is done. Primary experiments on measuring optical sphere mirrors with diameter of 50 mm are done to verify the influence of the stage moving errors. The rotatable optical devices that we designed are proved effective on eliminating the pitching error of the moving stage.

2-D dimensional standard is an important device for the calibration of coordinate measuring systems. In the past intercomparison of the calibration of 2-D dimensional standards, the equivalence tests among the calibration laboratories are performed based on the length measurement between measured coordinates of the points. Since, the measurand of the 2-D dimensional standards are the coordinates, the equivalence test should be performed based on the position measurement. Authors report the result of the intercomparison of the calibration of 2-D dimensional standards and its equivalence test based on the position measurement.

All materials spontaneously emit THz photons due to their fine activities at finite temperatures. Catching those spontaneous THz photons with high sensitivity and high spatial resolution would reveal detailed microscopic dynamics of matters. We have recently developed a THz microscope with the most sensitive THz detector, CSIP, and achieved the spatial resolution of 25 micrometers. In this report, we develop a scattering-type THz near-field microscope and perform super-resolution imaging of spontaneous radiation without any external illumination.

Generation, penetration, and propagation of surface plasmon waves excited around a septal wall between a pair of sub-wavelength holes on a metallic thin film has been analyzed by a three-dimensional numerical simulation software COMSOL Multiphysics (COMSOL AB, Sweden) with RF module, which are based on finite element method. The analytical 3D-model consists of four layers of quartz, metal, vacuum, and perfect matched layer (PML), and the metallic layer has the pair of through holes at the central region. The holes or metallic layer is uniformly illuminated by a linearly-polarized plane wave of laser light comes from the glass layer. Focusing and enhancement of the surface plasmons at the rear side of metallic film or the end of septal wall have been studied by changing (1) spacing of holes, (2) laser wavelength, (3) laser polarization, and (3) material and (4) thickness of metallic thin film. A series of the numerical results will be presented and discussed as application of the localized light source to the apex of fiber probe used in scanning near-field optical microscopy.
