Title: Production of hydrogen
Inventor: TAODA HIROSHI
IPC: C25B1/04
Filed: 1986-03-27
Abstract: PURPOSE:To easily obtain hydrogen as clean high energy fuel by dispersing a powdery mixture of TiO2 powder with Si powder in an aqueous methanol soln. or an aqueous soln. contg. methanol and ethanol and by irradiating light on the soln. CONSTITUTION:TiO2 powder is mixed with Si powder in 0.1-10 weight ratio. This powdery mixture is dispersed in an aqueous methanol soln. or an aqueous soln. contg. methanol and ethanol in a transparent vessel of glass, quartz or the like. Light from a light source such as a mercury lamp, a xenon lamp or the sun is then irradiated on the soln. to obtain high purity hydrogen. The irradiation is preferably carried out after N2 or an inert gas is blown into the soln. so as to remove the dissolved air. This method is economical because the reaction proceeds at room temp. without using an expensive noble metal.

Filed: 1985-04-01
Abstract: PURPOSE:To prevent the decrease in Zener breakdown voltage due to an edge effect effectively and to obtain a Schottky barrier diode having excellent high frequency characteristics, by forming a guard ring layer under an insulating film, which is formed on a semiconductor layer, so that the ring layer is not contacted with a metal layer, which is contacted with the semiconductor layer at an opening part in the insulating film. CONSTITUTION:A metal layer 4 is contacted with a semiconductor layer 3 in an opening part 8 provided in an insulating film 5 on a semiconductor layer 3. A guard ring layer 7 is formed in the surface of the semiconductor layer 3 along the periphery of the opening part 8 in a Schottky barrier diode. The guard ring layer 7 is formed so that it is not contacted with the metal layer 4. Therefore, injection of minority carriers is not yielded. As a result, the high frequency characteristics of the diode are not deteriorated. A depletion layer a2, which is formed by a P-N junction that is formed in a semiconductor substrate, is overlapped with a depletion layer a1, which is formed by Schottky contact, by the guard ring layer. Therefore, the concentration of an electric field at the end surface of the metal layer 4 due to an edge effect can be prevented, and a Zener voltage is not decreased.

Title: Piston for internal combustion engine
Inventor: MINAMOTO NAOKI
IPC: F02F3/00
Filed: 1986-03-28
Abstract: PURPOSE:To prevent an oscillating phenomenon, scarf abrasion and the like, by forming a crown section and a skirt section, independently from each other, then by coupling them with the use of a rib through the intermediary of a pin boss section so that they are formed in one unit body, and by reducing the wall thickness of an apex section extending from the crown section to at least a first piston ring. CONSTITUTION:A crown section 1 and a skirt sections 2 are coupled with each other through a pin boss section 4 integrally incorporated with the skirt section 4 and a rib 5. Accordingly, the quantity of heat transmitted from the crown section 1 to the skirt section 2 is also reduced so that the gap between the skirt section 2 and the associated cylinder bore may be made smaller, and therefore, the attitude of a piston is stabilized, resulting in that it is possible to reduce slap and noise. Further, a gouge 9 is formed in the upper section of inner peripheral surface of the crown section 1 or slits are formed in the apex section over the entire circumference thereof. Thus, it is possible to restrain the transmission of heat from the crown section so that the temperature of the piston ring groove may be lowered, thereby it is possible to enhance the wear-resistance of a piston ring and the piston groove section.

Title: Liquid crystal display element
Inventor: KAWAMOTO MASAHIRO
IPC: G09F9/00
Filed: 1981-05-14
Abstract: PURPOSE:To eliminate variations in tone and contrast with illumination light by correcting spectral wavelength characteristics of the illumination light. CONSTITUTION:In a liquid crystal display element which utilizes a guest-host (GH) effect, dichromatic paint in use does not absorbs >=650nm light. Therefore, although excellent black-and-white display is obtained by the illumination of a white fluorescent lamp, the long-wavelength light of tungsten lamp light from a tangusten lamp is not absorbed, but transmitted, so the display is red brown when no voltage is applied or white inclining to red when a voltage is applied, so that variations in tone and contrast increase. For this purpose, using a filter for cutting wavelength in a near infrared range solves a difference in spectral wavelength characteristics of illumination light approximately. The filter may be provided either separately from a cell or as a base plate.
