The relationships between the pressure in the tracheal tube cuff with the components of inflation gases and inhalation gases were examined by the simulation technique based on the gas transmission theory. We demonstrated that nitrous oxide gas in the inhalation gases transmitted in through cuff material so as to increase the cuff pressure, whereas carbon dioxide gas in the inflation gases moved out through cuff material and exerted to decrease the cuff pressure. These results show that a certain amount of carbon dioxide gas may compensate the transmission of nitrous oxide gas and keep the cuff pressure constant during nitrous oxide anesthesia.

A biochemical-pump with a flow cell was constructed by using active pressure increase through catalase asymmetric-immobilized membrane with hydrogen peroxide (H₂O₂) as enzyme substrate. By applying H₂O₂ to the lower case of the flow cell, the buffer slolution was continuous discarged from the upper cell-case by the active pressure increase through the enzyme membrane.

A cantilever type apparatus employed to examine the spring elastic limit, K_b of a steel plate with a thickness up to 0.1mm.
1) The K_b for specimens with thickness of 0.1mm and 0.2mm were comparable to the values obtained by the APT type machine at the test condition of L≈100t.
2) The K_b for ultra thin steel plates could be measured by the present testing machine as well.

The intermetallic TiFe alloy is a hydrogen storage alloy with a high hydrogen storage capacity, 1.8wt%, and a relatively low cost compared with other alloys. However, the TiFe alloy does not easily start to absorb hydrogen because of the presence of a very stable oxide layers covering the alloy surface. In order to activate the alloy, the alloy needs an intensive initial activation process at high temperatures over 720K under high hydrogen pressures over 6.5MPa. In this study, the intermetallic TiFe alloy was successfully prepared by mechanical alloying of Ti and Fe metals. The formed nano-TiFe alloy with a mixture of nano and amorphous structures was found to have a very easy, activation behavior compared with a standard polycrystalline TiFe alloy.

A wearable oxygen sensor (thickness: 84μm, width: 3mm) was constructed with. a metal weldable film, a porous membrane with electrolyte and a gas-permeable membrane coated with Pt and Ag/AgCl electrodes by micro-fabrication techniques. After evaluating the sensor characteristics, the wearable sensor was placed directly to the conjunctiva of Japanese white rabbit, thus successfully monitroing the output increase with inhaling 95% oxygen gas.

Effect of sheet electron beam irradiation on hardness, fracture diameter, fracture load and fracture toughness were studied for silica glass surface. Although the hardness value was not changed by the irradiation, it improved the brittleness, strength and fracture toughness of ultra-thin sheet of glass surface. The improvements can be explained by stress relaxation induced by increase in dangling bonds density.

In order to produce the hydrogen negative ions, we have proposed a newly designed system of a magnetized sheet plasma, TPD-SHEET-IV (Test Plasma produced by Directed current for SHEET plasma), crossed with a vertical gas-flow and an electron-emitter made of tungsten filaments. When the secondary hydrogen gas is fed to the hydrogen sheet plasma through the gas injector, the density of H^- is controlled by changing the emission current and the applied voltage of the electron-emitter. From results of the laser-photodetachement method, it is also shown that the characteristics of the density of H^- production depend on the cross section of the electron attachment to the vibrationally excited hydrogen molecules.

A fiber link with pupil slicer (FPS) consists of a lens array and 7 fibers, and an optics coincidencing output F-number to the input F-number of HDS. The FPS opens up possibility for opening the entrance aperture of the high dispersion spectrogragh (HDS) of Subaru telescope from 0.8 to 0.27 aresecond to attain resolving power three times as high as 150, 000 in comparison with entrance slit width. We present two concrete examples for applying the fiber, method for measuring the degree of fiber ratio degradation (FRD) of an optical fiber and spectroscopy observation of spectral type stars.

In order to recover phosphorus from ash of sewage sludge, many studies are going under way. However, phosphates recovered from this sludge were mainly composed of aluminum phosphate. To promote the utilization of recovered aluminum phosphate, zeolite formation process was studied. Aluminum phosphate was mixed with silicon dioxide powder and sodium carbonate, and heated at 900°C for 2 hours. Aluminum phosphate reacted with silicon dioxide and sodium carbonate, under this condition zeolite like substance was formed. This zeolite like substance was recovered by addition of water for dissolving sodium phosphate formed in this reaction followed by solid-liquid separation. Sodium phosphate was recovered from filtrate by vaporization.
