Title: Photoelectric smoke sensor
Inventor: TERASAWA TOMIZO
IPC: G08B17/107
Filed: 1991-09-13
Abstract: PURPOSE:To provide a photoelectric smoke sensor which can self-diagnose the degradation of smoke detection sensitivity. CONSTITUTION:Scattered light due to smoke of the light thrown from a light emitting circuit in a sensor enclosure is received by a light receiving circuit 2 and is converted to an electric signal, and the presence or the absence of smoke is discriminated by the magnitude of the output signal of the light receiving circuit 2. This photoelectric smoke sensor is provided with a detecting circuit 4 which detects the electric signal caused by stray light components due to light scattering and reflection in the sensor enclosure and a storage circuit 5 where the output from the detecting circuit 4 is stored, and the degradation in sensitivity of the sensor is discriminated in accordance with the magnitude of the stored output of the storage circuit 5. Consequently, the degradation of smoke detection sensitivity is self-diagnosed in the case of the degradation in sensitivity of the smoke sensor due to the degradation in light emission efficiency of a light emitting element, the degradation in light reception sensitivity of a light receiving element 21, the dirt of the sensor enclosure, or the like, and a probability of erroneous report due to the degradation of sensitivity is reduced.

Title: Memory managing system
Inventor: FUKUDA KOJI
IPC: G06F12/00
Filed: 1986-10-02
Abstract: PURPOSE:To reduce the generation of garbage collection, and to increase processing speed, by performing the coupling of an area targeted to be released at the time of releasing a memory, with a vacant area in the area, if they continue on a physical address. CONSTITUTION:When the request/release request of the memory is issued from a user 1, a memory managing means 2 delivers control to a memory segmenting means 3, and an area releasing means 4. The segmenting means 3 releases the vacant area to satisfy the request out of the vacant areas being chained to the start end 9 of a vacant block chain, if it exists, and adds it to the chain at the start end 10 of the chain of an area in use. If no vacant area exists, the control is delivered to an area re-constituting means 6, and the area chained to the start end 10 of the chain of the area in use is outputted to a second-order memory device 5. And after setting all of the areas 8 as the vacant areas, the area is re-constituted by re-inputting from the device 5, thereby, a large number of vacant areas are integrated as one large vacant area.

Title: Semiconductor integrated circuit device
Inventor: MASUI TOSHIHIKO
IPC: H01L21/33
Filed: 1983-12-14
Abstract: PURPOSE:To protect the 1st transistor (TR) against destruction due to static electricity by coupling the collector of the 2nd TR with the emitter of the 1st TR whose base is coupled with an input terminal, and providing a resistance between the emitter of the 1st TR and the collector of the 2nd TR. CONSTITUTION:A circuit in a figure constitutes an IC. Therefore, when a discharge bus due to static electricity is formed between an input terminal 1 or 2 and a terminal 15, a current flows in the order of the collector of a TR13, resistance 19, emitter and base of TR5 or 6, resistance 3 or 4, and terminal 1 or 2. Then, an overcurrent due to static electricity is limited by the resistance 19 to prevent the base-emitter junction of the TR5 and 6 which has small dielectric strength from being destroyed. Further, the current flowing through the resistance 19 is equal to that of the TR13, so no hindrance to differential amplification is caused. The resistance values of the resistances 3 and 4 are set to 100- 300OMEGA. Neither the attenuation of an input signal nor the generation of an offset voltage is generated because of the resistance 19.

IPC: H05B3/20
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To sufficiently transmit heat of a heating body to a person who is sitting on this heating apparatus in the case a cover is put on by forming a solid layer free of foam cells of a soft foam body in the outside of the heating body buried and fixed in the soft foam body. SOLUTION: A heating body 2 is buried and fixed in a soft foam body 9. An upper face solid layer 16 is formed in the upper face of the soft foam body 9 and the heating body 2 is buried and fixed. Further, a lower face solid layer 17 is formed in the lower face of the soft foam body 9 to sandwich the soft foam body 9 with low strength between the upper face solid layer 16 and it and protect the soft foam body 9 from the outside stress. Since the upper face solid layer 16 with high thermal conductivity is formed in the surface layer, in the case this electric heating apparatus is used while being covered with a cover 13 made of carbon fibers with high thermal conductivity, the heat from the heating body 2 is sufficiently transmitted through the upper face solid layer 16 and the cover 13 to a person who is sitting on.  Moreover, even in the case a knife, etc., is dropped on this electric heating apparatus, there is no possibility of damage and disconnection of the heating body 2 attributed to the existence of the upper face solid layer 16 and electric communication failure can be avoided.

Title: Information recording and reproducing device and method
Inventor: HASEGAWA SHINICHI
IPC: G11B19/02
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To enable restoration processing by detecting defect of operation of an optical block. SOLUTION: A controller 8 controls a DSP 10, and makes an optical block 3 output a slide servo signal moving to a most inner peripheral side of MO media 1 to a slide driver 13. The controller 8 discriminates whether a position of the optical block 3 is moved to the most inner peripheral part of the MO media 1 within 200 ms after this command. When it is discriminated that the position of the optical block 3 is not moved to the position corresponding to the most inner peripheral part of the MO media 1, the controller 8 makes the DSP 10 output the slide servo signal being a sine wave to the slide driver 13. The slide driver 13 applies voltage being the sine wave to a slide motor 3b based on this slide servo signal.  Thereby, as the optical block 3 is swung on an axis 3a, restoration processing from impossibility of operation due to hardening of grease and impossibility of operation due to a minute foreign matter can be performed.

Title: Ribbon foil material of au alloy for brazing semiconductor device without degrading in hardness with age
Inventor: YAMAMOTO SHIGERU
IPC: C22C5/02
Filed: 1987-09-21
Abstract: PURPOSE:To assure the effect of maintaining the hardness which is invariable with age by constituting a titled material of an Au alloy having the compsn. which contains Be and Ca respectively at specific concns. and consists of the balance specific weight % or above of Au and trace unavoidable impurities. CONSTITUTION:This foil material is constituted of the Au alloy which contains 1-45ppm Be and 1-45ppm Ca as alloy components and consists of the balance >=99.99wt.% Au and trace unavoidable impurities.

Title: Discharge lamp lighting circuit
Inventor: MINAMIMURA YUICHI
IPC: H05B41/392
Filed: 1989-09-14
Abstract: PURPOSE:To compensate luminance decrease at low temperature by installing a thermistor in an inverter lighting circuit consisting of a discharge lamp lighting circuit and a variable voltage output circuit. CONSTITUTION:A temperature sensor, for example a thermistor 5, is used in a dimmer circuit which determines an application voltage V0 to an inverter so as to provide the circuit with temperature properties. Starting up voltage property of a discharge lamp needs a higher voltage as the temperature is lower and the resistance of a thermistor becomes larger as the temperature is lower so that under a constant volume Vr, an output voltage V0 becomes higher as the temperature is lower. In this way, dimmer property can have the temperature property and thus dimmer range is widened and also lighting failure and luminance decrease at lower temperature are prevented.
