Title: Method of operation of kerosene space heater
Inventor: HASHIMA TAKAHARU
IPC: F23N5/20
Filed: 1991-10-29
Abstract: PURPOSE:To prevent the accumulation of harmful tar with a mechanism to prevent forgotten extinguishing and an operation extension mechanism being held by returning the operation to an ordinary operation after the time of operation is further extended and the temperature of a carburetor raised to high temperature for a short time. CONSTITUTION:The operation of a space heater is extended further for a certain time (3hrs.) by tuning an operation extension switch 23 ON. In addition, the temperature of a carburetor 6 is held for a short time (10sec.) at higher temperature (415 deg.C) than the ordinary operation temperature (280-285 deg.C) by raising the extent of heating of a carburetor heater 8. With this arrangement the tar accumulated inside the carburetor 6 is incinerated and removed. As soon as a short time (10sec.) has passed, the temperature of the carburetor 6 is returned to the ordinary operation temperature and the operation is extended another certain time (3hrs.). A drop in the combustion efficiency of a kerosene space heater is, therefore, prevented.

Title: Selector valve for water purifying device
Inventor: OKANO MASAAKI
IPC: C02F1/28
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To surely prevent the inflow of hot water to a water purifying cartridge side by providing this water purifying device with a moving part piece which is deformed and actuated by a raw water temp. and providing the device with a changeover mechanism for shutting off the raw water flow to the communicating port of the water purifying cartridge by moving the position of a changeover lever to a raw water discharge state position by the actuation of this moving part piece. SOLUTION: The raw water is not discharged from a raw water discharge port 5 and is discharged into the water purifying cartridge from the communicating port 4 of the water purifying cartridge opened by pushing back a ball 9 by a stay 8 for moving a water purification side ball when the raw water is admitted into the cartridge from a raw water inflow port 2 by changing over the changeover lever 6 to the purified water discharge state position. A curving plate 12 consisting of a shape memory alloy is deformed to push out a stay 10 for moving the raw water side ball and to push back the ball 11 when the hot water of the raw water flows into the cartridge from the raw water inflow port 2 in this state. The hot water is then discharged from the opened discharge port 5. At this time, a revolving shaft 7 rotates and the lever 6 returns to the raw water discharge state position.  The hot water is thus held in the state of not being discharged from the communicating port 4.

IPC: G05D1/02
Filed: 1989-12-01
Abstract: PURPOSE:To simply evade the obstacles for an unmanned vehicle by translating the reference coordinate axes away from the obstacles and defining the shifted coordinate axes as an obstacle evading source. CONSTITUTION:An unmanned carrier 11 is provided with a drive controller having a prescribed arithmetic/storage function which guides the carrier 11 along a driving course 10. Then the carrier 11 inputs the signals received from various sensors like a guidance detection coil, a steering angle detecting potentiometer of a steering/driving wheel 12, the encoders provided at the right and left fixed wheels 12a and 12b, etc. Then the position of an obstacle is computed on a carrier body fixed coordinate axes based on the detection signal of an obstacle sensor. At the same time, this position of the obstacle is transformed into a position on a reference coordinate axes. Then the reference coordinate axes are translated in the direction so as to be away from the obstacle, and the driving/steering control is carried out on the new coordinate axes. In such a constitution, the obstacles can be simply evaded with driving/steering operations performed in a short time and without increasing the constitutional scale.

Abstract: PURPOSE:To eliminate unstableness of setting of a breakdown voltage by restraining a current from flowing at a voltage not exceeding a breakdown voltage during reverse bias application which is caused by formation of a p-n junction at a crystal defect part generated below an edge of a selectively formed field oxide film. CONSTITUTION:A low concentration diffusion region 1 formed in a semiconductor substrate 8 is provided to an element region apart from an edge of a field oxide film 4 and a first high concentration diffusion region 2 is formed in the element region. Thereby, a p-n junction formed in a crystal defect part becomes a boundary between the semiconductor substrate and the first high concentration diffusion region 2 and breakdown occurs at a high voltage by a p-n junction between the low concentration diffusion region 1 and the first high concentration diffusion region 2. Therefore, a current does not flow at a low voltage and a breakdown voltage can be set readily.
