Visualization of 1MHz burst sine and pulsed ultrasonic wave propagation in the glass by using strobe photoelastic system introducing the sensitive tint method is carried out to improve the understanding of the sound field. Acoustic field data obtained by the system was captured by the CMOS camera and they were processed with integration, subtraction and normalization to enhance the S/N and contrast of the images. As the result, ultrasonic propagation of wavefront is clearly visualized in the low level excitation. Moreover, sign of positive and negative of ultrasonic sound pressure can be successfully identified in red and green, respectively.

We have succeeded to make paper sheets integrating hollow Kapok fibers containing solid fluorescence particles or magnetic particles. The focus of this work is to develop a novel paper sheet which integrates Kapok fibers containing thermo-sensitive inks. We utilized a thermo-sensitive ink which exhibits blue color under 40°C and pink color over 40°C. We have succeeded to make Kapok fibers containing the thermo-sensitive ink and paper sheet integrating the Kapok fibers. The paper sheet which integrates Kapok fibers containing thermo-sensitive inks changed its color reversibly depending on temperature. This observation suggests that the paper sheet utilizing Kapok fibers has the potential for rewritable paper sheet.

Epson has finely analyzed the requirements of business printers in view of changing office needs.  By optimally designing our unique print head technology for business applications and conducting repeated improvements, we have developed a new generation of business inkjet printers to rival or surpass laser printers. There is an established image of laser printers being for business use and inkjet printers being for the home. However, the efficiently simple printing process and mechanism of inkjet printers actually provides a variety of advantages over laser printers. Their high potential also allows for a wide range of applications, and in many commercial and industrial printing segments where precision, productivity and stability are mission critical, inkjet technology is rapidly becoming the industry standard as it evolves. The new office printers developed by Epson with Precision Core technology take full advantage of the superior capabilities of inkjet technology. In order to meet with the demand of business they also feature uncompromising levels of standard performance. From laser to business inkjet. Epson's evolving inkjet technology will revolutionize office printing.

Brother Industries, Ltd. has commercialized inkjet multifunction printers since 1997, and has developed and upgraded printers based on customer needs. Smaller and thinner size, printing on A3 size paper, and fast print speed are advantages of Brother at the present. The inkjet printhead which supports basic performances of the printer was changed from shear mode piezo type to direct mode piezo type, unimorph mode piezo type.  Latest PRIVIO NEO series has a unique structure of A4 size paper storage in landscape orientation to realize compact depth size, which enables to print on A3 size paper. Unimorph mode piezo inkjet printhead with wide print width of 35.6mm (1.4inches) and high frequency driving is mounted and this printhead realizes high speed printing of monochrome 22ipm, color 20ipm.

A long time has passed since the global warming, which is caused by greenhouse gases such as carbon dioxide (CO₂), started to be apprehended. A decade ago, saving power is the “eco” action and all manufacturers compete each other to have the lowest power consumption. However, in the international framework, saving power is just a part of the action. It is necessary to consider one product's environmental burden through its life time. Multi Function Peripheral (MFP) or printers consume paper. It is well known that paper has a large Carbon Foot Print (CFP) from its enormous energy consumption through production process. Toshiba Tec Corporation believes that it has a sustainable value to lessen this CFP, and in 2013, released the MFP with the erasable toner to reuse the paper. This paper reusing system is called “Loops”. In this article, I would like to explain the technology behind “Loops”. (Loops is the registered trademark in Japan of Toshiba Tec corporation.)

The multi-function product trend has been restructured from centralized full specific copier to decentralized compact medium class MFP which has adequate basic function in the workstyle change environment due to innovation of infrastructure i. e. mobility, SNS, cloud, and big data. New MC8 series is the product which provides benefit of low TCO, compact space, high print quality, and high efficient maintenance accessibility.  The concept of this product which was launched on July, 2015 is ‘down-time reduction' for end user. OKIDATA is leading new value in the MFP market with catchphrase ‘Working-Cost Diet'.

Recently, MFP business is moving from office use to public space usage and CPC click business is also changed to other system such as cloud business. Under such a situation, we launch new business which expand usage of MFP toward outside of office with not only business document print but also “Musical score print”, “Birthday newspaper print” and “Residence certificate print” in convenience stores. This paper introduce our Color MFP “MX series” which realizes operation like tablet by 10inch size big operation panel, and introduce how we support mentioned business. Finally, it also mention the view of MFP business in the future.

LS-4300DN/LS-4200DN/LS-2100DN series (Black & White printer), which are released in December 2012 by Kyocera Document Solutions Inc., extend the life of the processing unit to 500 thousands sheets by inventing the original a-C layer aim at extending the life of the a-Si drum and the design which extend life of main processing unit including toner. And therefore we success to decrease the frequency of exchange of processing unit in the machine life. As a result, the printer contribute to resource saving by reducing disposal parts and it marks top-class low running cost. In this report, we mention about the life extending technics which is equipped with the LS-4300DN/LS-4200DN/LS-2100DN series.

Konica Minolta has launched the bizhub C368 series as new A3 color MFPs. As one important part of the product concept, various technologies contributing to the reduction of the environmental impact have been implemented to these successor models of the bizhub C364e series.  This document explains the environmental load-reducing technologies achieving the top-class performance such as the increase in the usage of open-loop recycle material for exterior parts based on Konica Minolta's active promotion, the energy savings by the 0.5-watt sleep-mode, the decrease in the power consumption by a new fusing temperature control and the reduction of UFP emissions, which became an important topic in the European market in recent years.

User centricity is essential to product development. We collected and analyzed the voice of the customer on a new scale to identify all possible use of multifunction printers throughout users' work process. The findings are reflected into the imageRUNNER ADVANCE C3300, the successor model to the imageRUNNER C2200. imageRUNNER ADVANCE C3300 is a compact A3 color multifunction printer with 20-30ppm output speed, high image quality for business use, and lower total cost through ease of use and productivity requiring less time to perform various tasks such as consumables replacement. This thesis describes product summary and major technologies (high image quality, high stability, ease of use, and productivity) featured in the imageRUNNER ADVANCE C3300.

The ApeosPort-V series was developed by Fuji Xerox as its core products for office use. While providing a wide range of copying and printing speeds from 20 to 70 sheets per minute, the products also focus on the concept of RealGreen, which is further improved on this series. Employment of our unique human detection sensor technology, Smart WelcomEyes, which has already been adopted for the predecessor model, helped us to achieve a comfortable yet eco-friendly environment made possible by two additional cameras : the human detection and the face recognition cameras. In addition to this, our analyses have clarified how heat and sound is generated and transmitted, enabling a design that realizes quieter devices and satisfies both environmental performance and convenience for customers at an even higher level. This paper details two newly adopted technologies : the Smart WelcomEyes Advance technology introduced into the ApeosPort-V series and the noise reduction technology.
