Patent JP-S5565920-A (JP)
Title: Projector
Inventor: SUGIURA MUNEHARU
IPC: G03G15/041
Filed: 1978-11-14
Abstract: PURPOSE:To prevent the production of distortion of projected images by making the slit width at the specified width and correcting the imaging magnification in the slit lengthwise direction with the imaging optical system to the second plane in the device of slit-scanning the first plane by way of a polarizer and projecting to the second plane. CONSTITUTION:The image light of the first plane 6 goes through a slit of a width DELTAS which moves in the scanning direction parallel to a plane 6 in synchronization with the rotary scanning of a deflector 8 and a stationary lens group 7 and images on the deflector 8. This imaged image light is projected to the second plane  11 through the variable-power lens 10 formed by the first and second lens groups 9a, 9b movig in the optical axis direction in synchronization with turning of the deflector 8. If the slit width DELTAS of this slit is changed inversely proportionally according to magnifications at DELTAS<1/(Rp) at the time of projecting at an equal magnification with respect to the resolving power Rp of the image of the plane 11, the magnification change of the projected image in the scanning direction of the plane 6 is prevented by the slit and the magnification change in the direction rectangular to the scanning direction prevented by the lens 10, thus the distortion-free scanning projected image is obtained.

Title: Optical amplification monitor
Inventor: OKUNO HIDEKI
IPC: H04B10/296
Filed: 1995-06-07
Abstract: PURPOSE: To surely monitor the number of signal lights with a simple configuration by providing a device monitoring intermodulation light resulting from the signal light of 2-wavelength in a linear medium so as to detect the presence of the intermodulation light. CONSTITUTION: A fusion optical branching device 5 is used as a branching coupler 2 branching a signal light and an intermodulation light is used and an optical fiber grating 6 to reflect the signal light is used. When the signal light of 2-wavelength is propagated through an optical fiber transmission line 4, an intermodulation light of e.g. wavelength, 1552nm and 1557nm and that of 1547nm and 1562nm are given to the input of the fusion branch 5, and nearly 5% of each optical output is branched for monitoring and the signal light of two-wavelength is reflected in an optical fiber grating 6, then only the intermodulation light is give to a light receiving device 3, in which the light is converted into current. The intermodulation light is caused only when the signal light of 2-wavelength is propagated.  Thus, the number of received signal lights is monitored by monitoring the current of the light receiving device 2 and detecting only the presence of the intermodulation light.

Title: Fan heater
Inventor: MAKI MASAO
IPC: F24H3/04
Filed: 1983-07-29
Abstract: PURPOSE:To remove effectively the suspended dust and various offensive smell gas in a room by utilizing a filter provided with an electrostatic dust collecting filter and a reacting type absorbent. CONSTITUTION:A filter 12 provided with a dust preventing filter 13, a dielectric filter 14 and a reaction type absorbent 15 is arranged at an air blow-off outlet 2 in a room. A basic substance is preferable to be a reaction type absorbent, because the main component of an incomplete oxidizing product having offensive smell is an acidic substance. The basic substance such as a potassium carbonate and the like can be utilized as a supporting body supported by porous supporting material such as an active carbon and a zeolite and the like. By such a structure, the offensive smell gas and the suspended dust in the room can be effectively removed with the combination of the action of a fan heater, accordingly, the comfortable interior environment can be obtained.

Title: Vaporizable rust inhibitor of zinc
Inventor: KURIHARA SHIGEMI
IPC: C23F11/02
Filed: 1984-07-09
Abstract: PURPOSE:To provide a vaporizable rust inhibitor developing rust inhibiting effect even to a non-ferrous metal such as copper or zinc or an alloy thereof other than iron and an iron alloy, obtained by mixing cyclohexylammonium carbonate and benzotriazole or tolyltriazole in a predetermined ratio. CONSTITUTION:A vaporizable rust inhibitor is prepared by mixing 99-80pts.wt. of cyclohexylammonium carbonate (CHC) and 1-20pts.wt. of benzotriazole (BTA) or tolyltriazole (TTA). This rust inhibitor is different from such a case that each of CHC, BTA and TTA is used alone as a rust inhibitor and develops rust inhibiting effect not only to iron or an iron alloy but also to a non-ferrous metal such as copper, a copper alloy, zinc, zinc plating or Al. Therefore, an assembled product comprising different metals such as iron and copper can be inhibited from rust without disassembling the same.

Title: Control device for gas burner
Inventor: KONISHI MITSUNARI
IPC: F23N5/10
Filed: 1986-06-17
Abstract: PURPOSE:To prevent a disaster by causing a safety valve to automatically shut off the burning in case of an overheating of head objects by providing a temperature sensor that detects the temperature of the heated objects, and causing the safety valve to control the gas supply by way of the detection of the temperature sensor. CONSTITUTION:By operating a cock 1, a safety valve 2 is forcibly opened for the duration of the cock operation to allow the gas supply to a burner 4 for ignition. Then, the burning is started at the burner 4, and a thermocouple 3a is instantly heated. The heating of the thermocouple generates a thermal electromotive force which is applied to the safety valve 2 through a wire 3b to allow the continued burning. When the temperature of a heated object 6 is raised to a temperature that is dependent of the characteristics of a shape memory alloy 8 which is in contact with the heated object 6, the shape memory alloy returns to its original shape to operate a switch 10 by means of a converter 9 to open the electric circuit. Then, the safety valve is closed to shut off the gas to stop the burning, thereby preventing an overheating of the heated object 6.

Title: Controller of ac elevator
Inventor: YONEMOTO MASASHI
IPC: B66B1/30
Filed: 1985-06-27
Abstract: PURPOSE:To prevent an unnecessary power from being supplied to a motor at regeneratively operating time by detecting a supply power from an input current and thereby correcting a slip. CONSTITUTION:The input current of an inverter 5 is measured by a current detector 15 at regeneratively operating time, and the power supplied to the inverter is detected by a power detector 16. The initial value of a slip S is so set in correcting means in a microcomputer 22 that a regenerative power is not returned absolutely to a power source side, and the slip S is corrected to always operate slightly at power drive side. Thus, the slip at the regeneratively operating time can be set to the optimum value to prevent the unnecessary power from being supplied to the motor at the regeneratively operating time, and a device for processing the regenerative power can be eliminated to simplify a controller.

Title: Feeding device for chip electronic parts
Inventor: HAEDA YOSHIO
IPC: H05K13/02
Filed: 1987-06-08
Abstract: PURPOSE:To prevent shifting in the position of a chip with respect to an adsorbing nozzle due to its shaking, etc., by providing flanks for preventing both lever ends from interfering with each other when a swinging lever is horizontally moved to right under a lever, on the end corner part of the lever and the end corner part of the switching lever. CONSTITUTION:Flanks 31, 32 are formed on the end corner part of a swinging lever 8 and the end corner part of a lever 20 respectively. Hence, even if the gap between the ends of both levers 8, 20 is made nearly zero, the swinging lever 8 can be horizontally moved to right under the lever 20 without interfering with each other. Thereby, since the lever 20 depresses the swinging lever 8 under a condition of slow motion, the impact force with which the lever 20 is brought into contact with the swinging lever 8 can be extremely small. Accordingly, a sprocket 7 can gently pull a holding tape 2 preventing shifting in the position of a clip with respect to an adsorbing nozzle 4 due to its shaking, etc.
