Title: Manufacture of photovoltaic device
Inventor: NAKAJIMA YUKIO
IPC: H01L31/18
Filed: 1985-08-10
Abstract: PURPOSE:To contribute to an effective photoelectric conversion by forming a p-type layer and/or an n-type layer by photodecomposing raw gas which contains silicon compound gas, and forming the p-type and i-type layers by plasma decomposing the raw gas which contains silicon compound gas to obtain an impurity layer of high film quality. CONSTITUTION:A pin junction type photoactive layer 3 is formed of ultrafine crystal silicon formed by photodecomposing raw gas which contains doping gas such as B2H6, PH3 for controlling valency electron in silicon compound gas of SiH4, Si2H6, Si2F6 in a p-type layer 3p and an n-type layer 3n to effectively photoelectrically convert the p-type layer 3p, the i-type layer 3i and the n-type layer 3n as seen not only from the layer 3i but from all layers, i.e., from a photoreceiving electrode 2 side.

Title: Active heat cutoff method using fiber collection or porous body
Inventor: MARUYAMA SHIGENAO
IPC: G21C11/08
Filed: 1989-07-08
Abstract: PURPOSE:To efficiently cutoff heat by letting working gas of low temperature permeate from the back of a layer made of optically semipermeable porous body into the layer and by discharging working gas heated by scattering and absorbing a heat radiation ray in the layer. CONSTITUTION:Working gas of low temperature is permeated in a layer composed of a porous body having optically semipermeable fine structure or a layer made of collecting fiber from the back thereof. Since this allows the most part of heat radiation ray of high temperature to permeate the surface, scatter and absorb it in the layer, a solid wall surface remains not becoming high temperature so much. The porous body heated by a heat radiation ray is efficiently cooled by low temperature gas flowing in reverse, and the working gas heated is discharged out of the system. Thus, heat can be efficiently cutoff from a heat radiation ray or an environment of high temperature.

Abstract: PURPOSE:To form beautifully colored pattern films which differ in color tones between corner parts and the other parts and have excellent durability of the surfaces of Al (alloy) materials to be treated by subjecting said materials after anodized films are formed to a series of treatments including two times of fore and post coloring treatments. CONSTITUTION:An anodized film is formed on the surface of Al (alloy), and is subjected to electrolytic coloring (primary coloring) in a metallic salt soln. After paint is stuck on the colored material by a dip painting method, the solvent of the paint is evaporated to form the paint films differing in thickness distributions between corner parts and the other parts on the surface of the material to be treated. If necessary, said material is anodically electrolyzed in an aq. acidic soln. to decolor only the corner parts where the sticking of the paint is small selectively. The decolored material is subjected to electrolytic coloring to provide the color tone differing from that of the primary coloring whereby only the corner parts are colored secondarily. Thereafter the material is immersed in a bath contg. an org. solvent to dissolve the paint film on the surface, and again the material is subjected to painting, whereby the pattern coloring of the Al (alloy) is completed.

IPC: H02H3/20
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To quickly detect abnormality and stop the output of a PWM converter device when the abnormality occurs in a control circuit, due to reasons other than the power supply voltage, and at the same time, to detect not only the voltage rise of the converter device, but also the voltage drop, by judging an error voltage as the excessive error voltage for switching off a self-arc-extinguishing element when the error voltage is higher than a prescribed value. SOLUTION: A DC-voltage converting means 20 inputs the power supply voltage, detected by means of a power supply voltage detecting means 8 and converts the voltage into a DC voltage by multiplying the voltage by a prescribed coefficient (for example, 1.4). A DC-voltage command computing means 21 inputs the converted DC power voltage value and generates a DC-voltage command value by adding a prescribed value to the converted value. An error-voltage computing means compares the DC voltage command value, outputted from a first-order time lag filter 22 with the DC output voltage detected by means of a DC-voltage detecting means 6 and calculates an error voltage from the formula: error voltage = DC voltage command value-DC output voltage. An excessive error difference voltage detecting means 27 inputs the error voltage and, when the error voltage is higher than a prescribed value, judges the error voltage as the excessive error difference voltage for switching off a self-arc- extinguishing element.
