Title: Circuit for driving switching element
Inventor: NAKAMURA KIMIYA
IPC: H03K17/732
Filed: 1987-03-13
Abstract: PURPOSE:To attain the high frequency operation of a switching element by using the higher on-gate generating circuit of a specified constitution so as to hold a higher on-gate gate current longer with a simple circuit constitution. CONSTITUTION:A timing pulse generating circuit 1 receives a timing signal SG1 in on off-state and an off-gate switching circuit 5 is operated, and a negative voltage V2 is applied to turn off a switching element 4. Moreover, the negative voltage V2 is applied to an emitter of a transistor (TR) 1 to be a conductive state. On the other hand, when the signal SG1 is turned from off to on, the circuit 1 operates an on-gate switch circuit 2, stops the circuit 5 and the circuit 2 uses a positive voltage V1 to apply a forward bias between the collector and emitter of the TR 1. On the other hand, the potential of the emitter terminal is zero and the TR 1 is going to be turned off. However, the TR 1 holds the on-state till the carrier between base and emitter is extracted and a gate current (i) (higher on-gate current ia) flows and the element is turned on.

Title: Manufacture of composite resin foam
Inventor: NAKAMURA YASUO
IPC: C08L101/16
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To foam in a simple, safe, and cheap manner, using a water contg. a plant residue. SOLUTION: A material W mainly composed of a powdered thermosetting resin and a plant residue such as water contg. bean curd lees generated in food processing are stirred and mixed, then, this material W is put into the hopper 6 of an extruder 1. The material W is heated to melt with a heater 5 equipped on the exterior of a cylinder 2, and kneaded while progressing forward with a screw 4, and the melted mixture M is foamed pushing through a dice 3 at the end of the cylinder 2. While the material W is kneaded in the extruder, the plant residue is uniformly dispersed in the thermosetting resin. The water contained in the plant residue acts as a foaming agent, and since it is uniformly dispersed as a small particle in the thermosetting resin, a composite form with a uniformly dispersed independent minute foam is molded.  This composite foam has almost the same mechanical characteristic as the thermosetting resin foam and can be used as an alternative material and also has biodegradability.

In the case the quantity of rice is small, by operation of the microcomputer, a fan 10 operates for a prescribed time, remaining heat of the electric heater 7 is exhausted forcibly to the outside of a protective frame 4, and rice cooking is completed. In the case the quantity of rice is large, the fan 10 is not operated and rice cooking is completed. In such a way, an excellent rice cooking performance is always secured irrespective of the quantity of rice.
