Title: Ceramic mold for precise casting
Inventor: YOSHIOKA HIDEHO
IPC: B22C1/08
Filed: 1988-02-09
Abstract: PURPOSE:To improve the strength, dimensional accuracy and quality of a casting part by mixing the substance generating a reducing gas at casting time with a refractory granular body and forming and sintering the mixture thereof. CONSTITUTION:The substance of a graphite, etc., generating a reducing gas at casting time is mixed with the refractory granular body of zircon sand and/or zircon flour, etc., to form and sinter a mixture. The substance of a graphite, etc., above-mentioned is mixed at the rate of about 0.5-20wt.% with the refractory granular body, the obtd. flowing refractory slurry is poured onto a pattern and gelatinized. Primary and secondary sinterings are then performed on the formed mold to complete the mold. When a molten metal or alloy is poured into the mold, the contact face of the mold and molten metal forms a reducing atm., the oxidation of the casting part surface is restricted and the forming of the decarbonated layer just under the surface is prevented. The strength of a casting is thus improved and due to no generation of scale oxide the dimensional accuracy is improved and the quality is improved as well.

Title: Detecting device for presence/absence of sheet
Inventor: SEZOKO SHINICHI
IPC: G03G15/00
Filed: 1986-02-12
Abstract: PURPOSE:To detect whether there is a sheet or not surely, so as to prevent any false detection due to a color of the sheet, by photoelectrically converting reflected or transmitted light from a light source through a receiving element, and judging the existence of the sheet when a potential in the absence of the sheet differs from that in the existence thereof to an extent exceeding a predetermined value. CONSTITUTION:Optical sensors 22, 23 are provided for detecting whether there is a document 3 or not when the document 3 is fed in the direction of an arrow 21 along a guide 20. A first sensor 22 for detecting the document 3 is located near by the guide 20, and a second sensor 23 is provided on the outside area of the guide 20, where there is not any possible passing of the document 3. Photoelectrically converted outputs 22a, 23a of receiving elements of both sensors 22, 23 are inputted to a comparing amplifier 28 through level regulating amplifiers 26, 27 in a processor 30. If the amplifiers 26, 27 are previously adjusted to equalize the levels of both outputs 22a, 23a in the absent state of the document 3, the converted output 22a is increased by the existence of the document 3, and it is judged that there is a document 3 when a potential difference exceeds a predetermined value. Thereby, it is possible to surely detect whether there is the document 3 or not without the occurrence of any false detection due to a color.
Patent JP-S59154082-A (JP)
Title: Photosensor
Inventor: NOMOTO TSUTOMU
IPC: H01L31/0216
Filed: 1983-02-22
Abstract: PURPOSE:To obtain the titled device which makes an incident light efficiently reach a P-I film interface and can obtain an output signal efficiently by a method wherein a transparent insulation layer having partial defect parts and a layer composed by forming boron doped layers at said parts are provided between a clear electrode and an amorphous Si layer. CONSTITUTION:The partial defect parts 3a-3p are formed by etching the transparent insulation layer 7 by photolithography in lattice form. A boron doped amorphous Si film is adhered over the entire surfaces at these defect parts by a glow discharging method, and thereafter said film is processed by photolithography etching. Thereby, the amount of light reaching the I type layer 4 can be increased by reducing the amount of light absorption due to the boron doped layer. As a result, the pair of electrons-holes generated in the I type layer 4 by the light passing through the insulation layer 7 makes the resistance value of said layer 4 reduce and transfers to the P-I film interface, thus enabling to largely vary the depletion layer width at said interface in suitable manner. Thus, the photosensitivity remarkably improves, therefore high speed photo detection can be performed without necessitating an amplifier of a high gain.

Title: Ac load control circuit
Inventor: KANDA HAJIME
IPC: G05F1/10
Filed: 1984-02-16
Abstract: PURPOSE:To improve the insulating performance between an AC circuit and a DC circuit and to improve the safety by using a solid-state relay and a photocoupler to ensure the double insulation between both circuits. CONSTITUTION:The DC side of a solid-state relay SSR12 is connected to an SSR control DC power supply 15 of a power supply circuit 14 via a photodetecting element of a photocoupler 13. An engine driver 17 performs the sequence control of each part of a laser printer and applies the heater ON/OFF control signal to the base of a transistor TR18. When the TR18 is turned on and off, the photodetecting element of the photocoupler 13 is turned on by the output of a DC power supply 19. Therefore the output of the power supply 15 is applied to the DC side of the SSR12, and the SSR12 is driven. Then the AC side of the SSR12 is short-circuited, and the SSR12 turns on a heater 11 with input of the AC power supply voltage. When the TR18 is turned off, the light emitting element of the photocoupler 13 is turned off. Thus the photodetecting element is also turned off. As a result, the DC side of the SSR12 is not driven any more with the AC side opened. Thus the heater 11 is turned off.
