Title: Electric appliance with gas sensor
Inventor: KAWAMURA MITSURU
IPC: F23N5/00
Filed: 1986-08-12
Abstract: PURPOSE:To prevent the malfunction of a gas sensor to improve reliability by a method wherein a sensitivity control means for a gas sensor is placed and the output from the sensor is delayed to judge and also an alarm is issued before an electric appliance is controlled. CONSTITUTION:When a stove is operated, a gas sensor detects gas density from time to time. A judging circuit 5 emits a reaction signal when a detected gas density is higher than a set one. A CPU 7 judges the existence of the reaction signal and when the signal is interrupted, the CPU 7 resets the primary timer means 8. Therefore, such malfunction that an alarm is issued or combustion is stopped when ventilation is not particularly requested is prevented and the reaction of the sensor is delayed. After the counting of the primary set time is finished, the CPU 7 judges that the gas density is high continuously during the set time and the condition is so dangerous as to necessitate ventilation and starts the secondary timer means 9 and also turns on and off an LED 12 to alarm and request ventilation.

Title: Cooling structure of printed wiring board
Inventor: KOJIMA YASUSHI
IPC: H01L23/38
Filed: 1987-07-28
Abstract: PURPOSE:To make cooling efficiency largely higher than natural air-cooling by forcedly cooling a heat pipe connected between an electronic part and a radiation fin by using a Peltier element. CONSTITUTION:Heat generated by an electronic part 16 is transmitted over the endothermic side of a Peltier element 18 by a heat pipe 14 and a heat- collecting heat pipe 15, and cooled. Heat cooled on the endothermic side is dissipated on the exothermic side of the element 18, and a heat dissipation side heat pipe 24 to which radiation fins 22 are fitted is connected on the exothermic side of the element, thus transmitting heat dissipated from the element 18 over the fins 22 by the pipe 24, then dissipating heat into peripheral air. Since the heat of the fins 22 is dissipated from the exhaust side of the under-side of a heat shield plate 20, the heat of the fins has no effect on an atmospheric temperature on the suction side of the heat shield plate 20. Accordingly, cooling efficient is made largely higher than natural air-cooling.

Title: Cooking oven
Inventor: HAYASE MASAO
IPC: H05B11/00
Filed: 1989-07-20
Abstract: PURPOSE:To detect the completion of heating regardless of water content and color of food by a method wherein the temperature drop in a compartment due to the latent heat of vaporization is detected by a heating completion detector, and a controller stops power supply to heaters on receipt of the heating completion information. CONSTITUTION:When food A is heated and its temperature reaches 100 deg.C, the heat rays from infrared ray heaters 3 and 4 are absorbed by steam and carbon dioxide gas, etc. generated from the food A resulting in a temporary decrease in the temperature in the compartment. The temperature drop in the compartment due to the latent heat of steam is detected by a compartment temperature sensor 7, and the temperature data is supplied to a detection circuit 14. The detection circuit 14 compares the present temperature with the temperature detected by the compartment temperature sensor 7, decides that cooking of food A completes when the detected temperature becomes lower than a given value, and supplies this signal to a control circuit 15. On receipt of the decision signal, the control circuit 15 turns a drive circuit 17 off. As a result, power supply to the infrared lay heaters 3 and 4, a magnetron 8 and an exhaust fan 11 is stopped.

Title: Video signal output circuit
Inventor: TANIZOE HIDEKI
IPC: H04N9/64
Filed: 1986-08-14
Abstract: PURPOSE:To obtain a video signal output circuit which does not require a luminance signal driving transistor TR and is advantageous with respect to cost, by connecting one end of a series connection body of a diode and a semi- solid resistance to the base of a signal driving TR in the channel of each color and inputting a signal corresponding to the luminance signal to the other end. CONSTITUTION: The output of an inverter gate 11 is in a low level and a signal driving TR 6 and a video signal output TR 2 are turned on when a signal in a high level is inputted to the gate 11 of a red channel Rch (the same may be said of channels of the other colors). When the input signal of the gate 11 is in the low level, the output of the gate 11 is in the high level and TR 6 and 2 are turned off. A switching diode 20 is tnrned off or on to change the base current of the TR 6 and the emitter current of the TR 2 according as a signal I is in the low level or the high level. Consequently, the level of the signal inputted to a cathode 1A from the TR 2 is changed to display colors on a C-CRT 1.

Title: Porous sintered body and its production
Inventor: KAITANI KATSUMI
IPC: B22F9/00
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To realize an optional cubic shape excellent in general applicability, a smooth surface and high dimensional precision by subjecting a preliminarily compacted part composed of single or two or more different kinds of metallic fine pieces and obtd. by being pressurized while high electric current is caused to flow to repressurizing in a prescribed die. SOLUTION: A preliminarily compacted part obtd. by preliminary compacting is discharged as being in a heat-generated state from a compacting device. Then, the preliminarily compacted part is charged to a die 18 as it is in the case of being in a big final product and is cut to required dimensions and is charged to the die 18 in the case the final product is smaller than the preliminarily compacted part. In the die 18, it is repressurized under the pressure higher than that in the preliminary compacting and is compacted into an optional cubic shape to obtain the objective porous sintered body 21. Since a heater or the like for heating is not generally set to the die 18, the temp. of the preliminarily compacted part is reduced from the initial heat generating temp.  Preferably, the inside temp. of the preliminarily compacted part at the time of being repressurized by the die 18 is controlled to at least about 10 to 15% of the m.p. of the metallic fine pieces as the raw material.
