Title: Thin film semiconductor device and manufacture thereof
Inventor: SERIKAWA TADASHI
IPC: H01L27/12
Filed: 1988-05-11
Abstract: PURPOSE:To provide a short channel, to eliminate crystal grain boundaries which disturb the transportation of carrier from a channel region, and to provide high performance of a semiconductor device by forming a channel on the sidewall of a pattern of a thin polycrystalline semiconductor film. CONSTITUTION:A first conductive layer 22 and a second conductive layer 24 are operated as source and drain electrodes. Accordingly, when positive or negative control voltage is applied to a gate electrode 26, carrier made of electron or hole is induced at the sidewall of the pattern of a thin semiconductor film 22 to form a channel. When a voltage is applied between the layer 22 and the layer 24 in this state, the carrier flows along the end of the pattern of the thin semiconductor film, and operates as a semiconductor device. Thus, the length of the channel becomes substantially equal to the thickness of the thin semiconductor film, crystal grain boundaries 23' become directed substantially parallel to the flow of the carrier so as not to disturb the transportation of the carrier, thereby improving the performance of the semiconductor device.

Title: Infrared radiation type heat radiator
Inventor: HIKINO TADASHI
IPC: F24C7/06
Filed: 1981-07-17
Abstract: PURPOSE:To improve durability and radiation efficiency by using a reflector coated with silicon compound protective film of less than a specific thickness over an aluminum plate of a specific value of purity and surface coarseness. CONSTITUTION:In an electric stove having a reflector 1, side plate 3 and inside roof plate 4 and a quartz tube heater 2 inside the body, the reflector is made of silicon oxide protective film of less than 3mu thickness vacuum-vapored on a smooth surface of aluminum plate of less than 0.1mu surface coarseness and 98% purity. Because the silicon oxide film is harder than aluminum, surface rigidity is improved and, because main radiant wave radiated from the quartz tube heater 2 is longer than the thickness of the protective film, the radiant wave is not absorbed by the film and is reflected by the aluminum, thus improving radiation efficiency.

IPC: H01J31/18
Filed: 1978-09-14
Abstract: PURPOSE: To make the promotion of improvement of dielectric characteristic of the tube, with a discharge prevented within the tube, by such means that, with a ring- shape conductive unit provided throughout the full circumference along a collector mesh ring between the first electrode and internal conductive film, a potential of storage mesh be given to the above.  
     CONSTITUTION: Between a first electrode of aluminum pack 7 and internal conductive film 34, along a collector mesh ring 36, near the inner face 35 of insulating peripheral vessel, is provided a ring-shape conductive unit 39 throughout the circumference. Consequently, a flood beam 37, when colliding against a point P 1  partially on the insulating peripheral vessel inner face 35 even with a secondary electron 38 emitted, is all absorbed by the conductive unit 39, storage mesh 9 and collector mesh 10, not capable of reaching the aluminum pack 7. Accordingly, the potential at the point P 1  never becomes higher than that of the storage mesh 9 and the collector mesh 10, thus a discharge can be prevented between the point P 1  and an end part of the internal conductive film 34.

Title: Rotational direction discriminator of stationary type
Inventor: HIRAI AKIRA
IPC: H02P1/42
Filed: 1978-09-14
Abstract: PURPOSE: To make it possible to discriminate the roational direction as a motor without any rotor by using the phase difference between the voltage to be impressed upon the primary winding of a stator and the secondary voltage to be induced in an auxiliary wiring.  
     CONSTITUTION: Both the voltage, which is to be impressed upon the main wiring 1 of a stator to be tested, and the voltage to be induced in an auxiliary wiring 2 are fed through amplifiers 4 and 4', respectively, to waveform shaping circuits 7 and 7' and are then differentiated by differential circuits 8 and 8'. The positive pulses of the circuit 8 and the negative pulses of the circuit 8' are fed as trigger pulses to bistable multivibrator 9. Then, in the forward rotations, square waves having a longer positive duty are generated whereas in the backward rotations waves having a longer negative duty are generated. If these are integrated at 10, the DC voltages of positive and negative polarities are indicated in a meter 11, respectively, in the positive and negative cases. Thus, the direction of rotation can be easily discriminated without any special detector.

Abstract: PURPOSE:To simplify the constitution of a device, by using a thermistor as a heater, as well. CONSTITUTION:A thermistor 6 is made to have both functions of a heater and a temperature sensor. Since only the thermistor is connected to a controller 7, its structure is simplified and only two lead wires are enough. Furthermore, since the thermsistor 6 serves both as a thermistor function and a heater function, a temprature of the heater itself is measured, therefore, the device generates no oscillation, and in the event of disconnection, heating to an object 1 by the controller 7 is stopped as a matter of course, therefore, a temperature of the object 1 does not rise excessively, and safety is secured. The controller 7 consists of, for instance, a variable current source 8, a comparator 9, fixed resistances R1, R2, and a variable resistance R3, and when a bridging circuit is constituted of the fixed resistances R1, R2, the variable resistance R3 and a resistance Rt of the thermistor 6, the resistance Rt of the thermistor 6 is controlled so as to be held at a constant value.
