Title: Heat-cooking apparatus
Inventor: WAKI MAKIKO
IPC: F24C14/02
Filed: 1989-02-28
Abstract: PURPOSE:To increase the temperature of a coating layer from its interior, and to enable oil stains to be catalytically burnt out by providing the coating layer dispersed with a specific composite oxide and silicon carbide on the inner walls of the heating chamber of an oven/microwave oven, and by maintaining the coating layer at a temperature at which catalysts sufficiently function, by a heater, while further irradiating microwaves to allow the silicon carbide to generate heat. CONSTITUTION:A coating layer dispersed with a microwave loss material mainly composed of a composite oxide 1 represented by CeCux and Mn1-x0y (0<x<1 and y>0) and silicon carbide 2 is formed on the inner walls 4 of the heating chamber of an oven/microwave oven. By alternatingly effecting the supply of power to a heater and the irradiation of microwaves, the whole inner walls 4 of the heating chamber are maintained at a temperature at which catalysts uniformly function, by the heater while, furthermore, the silicon carbide 2 absorbs the microwaves to generate heat, whereby oil stains can be more effectively burnt out with the composite oxide. According to this method, a large amount of oil stains can be removed in a short period of time even if the capacity of the heater is not increased, and the cleaning cost can be reduced.

Title: Optical reproducing device
Inventor: ICHINOSE AKIRA
IPC: H04N5/85
Filed: 1979-04-17
Abstract: PURPOSE:To hold the loop gain of tracking control constant without reference to a reproduction position by making the amplification factor of an amplifier at its inner circumference greater than that at its outer circumference. CONSTITUTION:Variable gain AC amplifiers 19a and 19b vary in amplification factor according to a DC output voltage corresponding to a reproduction position. Then, position detection part 20 detects how much disk 8 has been conveyed and while A and B terminals of resistor 21 are fixed to the unit, the C terminal moves as disk motor 9 moves. When the A terminal is applied with +VCC and the B terminal is grounded, motor 9 moves and as the reproduction position of the disk moves from its outer circumference toward its inner circumference, the C terminal moves from the B terminal toward the A terminal, so that the voltage of the C terminal will gradually increase from zero up to +VCC according to the movement of the reproduction position of the disk from its outer circumference to the inner circumference. Amplification factors of amplifiers 19a and 19b are increased according to this control DC voltage, so that the reduction of the amplitude of a reproduction output at the reproduction position can be compensated.

Title: Production of electrophotographic photoreceptor
Inventor: ARAKI TOSHIYUKI
IPC: G03G5/10
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To suppress the nonuniformity of the image characteristics of an electrophotographic photoreceptor formed by using an aluminum substrate and to ameliorate the unequal images relating to the electrophotographic photoreceptor formed by using a port hole tube by subjecting the substrate to a superheat treatment at a specific temp. prior to a washing treatment with a water system. SOLUTION: The conductive substrate consisting of aluminum or aluminum alloy is treated by an aq. washing liquid and thereafter, a photosensitive layer is formed on the surface of this conductive substrate. In such a case, the surface of the conductive substrate is heated to >=100 deg. before the treatment by the aq. washing liquid. This heat treatment may be executed at an arbitrary temp. if the temp. is above 100 deg.C. The execution of the heat treatment in a range of 120 to 200 deg. is more preferable. If the heat treatment temp. is too low, the effect of the heat treatment is low and is, therefore, not applicable to practicable use.  If the heat treatment temp. is too high, the transfer of the trace metal on the substrate and the formation of a thermally oxidized film take place and the characteristics thereof change and, therefore, the execution of such heat treatment is industrially costly.

Title: Carbon-containing refractory
Inventor: OKAMOTO TAKESHI
IPC: C04B41/83
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To extremely reduce the damage by the oxidation of carbon in a carbon-containing refractory and further improve the tolerance thereof by coating a coating material containing a specific proportion of aluminum on the surface. SOLUTION: This carbon-containing refractory is obtained by coating a coating material containing 6-30wt.% aluminum on the carbon-containing refractory in 10-3,000μm thickness. The coating material acts as a coating layer, blocks the penetration of an oxidative gas such as air into the interior of the carbon-containing refractory and has effects to prevent the refractory from becoming weak by decarbonization by the oxidation of the carbon. Because, the aluminum foils present in a dispersing state in the coating material are strongly adhered to each other through resin component in the coating material and maintain airtightness up to about 600 deg.C. Further, at above 600 deg.C, the aluminum forms an alumina thin layer by an oxidation reaction and a dense layer are formed on the surface. Thereby, the penetration of the oxidative gas is blocked penetrating into the refractory by the aluminum foil and the alumina, and the oxidation of the carbon in the carbon-containing refractory is prevented.
