Title: Planar-type heterojunction semiconductor photodetector
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/107
Filed: 1987-08-19
Abstract: PURPOSE:To form a guard ring whose curvature is relaxed by a method wherein a forbidden-band width in an avalanche multiplication layer is increased to be a stepped shape of two or more steps as the layer becomes more distant from a light-absorbing layer so that an impurity can be diffused deeply. CONSTITUTION:A guard ring 5' completely covers the curvature at an edge part of a stepped-shape p+-n junction, and relaxes the curvature at the edge part of the guard ring 5' to a certain extent; as a result, a breakdown voltage of the guard ring 5' itself is increased. Therefore, a forbidden-band width in an avalanche multiplication layer is increased in a stepped shape of two or more steps as the layer becomes more distant from a light-absorbing layer 3. That is to say, when a p-type impurity is diffused into an n-type conductive region or an ion is implanted, the coupling energy between atoms constituting a semiconductor becomes strong as the forbidden-band width in the n-type conductive region becomes large. Accordingly, the probability to substitute the atoms constituting the semiconductor with the impurity is lowered; the impurity is diffused deeply; the guard ring 5' whose curvature has been relaxed can be formed.

Title: Trigger circuit of gate turn-off thyristor
Inventor: TAKIGAMI KATSUHIKO
IPC: H03K17/732
Filed: 1983-11-02
Abstract: PURPOSE:To improve the turn-on characteristic of the GTO by connecting a capacitor in parallel with a current limit resistor where switching elements are connected in series between an anode and a gate of the GTO. CONSTITUTION:When a switching element 2 comprising an SCR or the like is turned on, since a capacitor 4 is connected in parallel with a current limit resistor 3, an auxiliary circuit current IS flows largely in a transient way, the turn- on time of the GTO1 is decreased remarkably and an anode voltage VA is dropped quickly. Then the charging of the capacitor 4 is attained quickly and after the anode voltage VA is decreased, the auxiliary circuit current IS is decreased rapidly. Thus, the thyristor 2 of the auxiliary circuit is miniaturized and an excellent turn-on characteristic of the GTO1 over a wide anode voltage range is obtained.

Title: Constant current drive circuit
Inventor: SHINOMIYA KOUJI
IPC: H03F3/34
Filed: 1983-11-01
Abstract: PURPOSE:To control the dependency of an output current on temperature by allowing a constant current source to generate a current proportional to the absolute temperature so as to compensate the temperature characteristic of a drive circuit. CONSTITUTION:A current IT from a current source flows as a collector current of a transistor (TR) Q1 and also flows as a collector current of a TRQ3 to give a voltage drop across a resistor R2. On the other hand, a collector current of the TRQ1 is equal to a current flowing to a resistor R1, VBE(Q1)/R1, where VBE is a base-emitter voltage of the TRQ1, and flows as a collector current of the TRQ3 and produces a voltage drop across the resistor R2. That is, these two currents are summed at the resistor R2 and produces a voltage drop at the resistor R2. Since the current mirror circuit is constituted of the TRs Q3, Q4, the output current is extracted as a collector current of a TRQ4 corresponding to the voltage drop of the resistor R2, and the control of the temperature dependency of the output current is attained by making a current IT to a current proportional to the absolute temperature including the temperature coefficient of the resistors R1, R2 and the voltage VBE(Q1).

Title: Cellulose-processing process
Inventor: KAARU BUREDERETSUKU
IPC: C08B1/02
Filed: 1994-08-31
Abstract: The process for the treatment of cellulose for activation for subsequent chemical reactions by bringing the cellulose in contact with liquid ammonia at a pressure higher than atmospheric pressure in a pressure vessel and subsequent expansion by rapid reduction of the pressure to atmospheric pressure, is carried out by using a cellulose pulp of an alpha-cellulose content of at least 92 mass %, letting the ammonia act on the pulp at room temperature or at a temperature higher than room temperature, after the expansion, removing the ammonia then still remaining in the pressure vessel except for a minimum content at which the state of activation reached by the action of the ammonia is still maintained and finally replacing the residual ammonia still needed to maintain the state of activation by another swelling or inclusion agent. The process is suitable, also on a large industrial scale, especially for the activation of pulp subsequently to be acetylated and makes possible to achieve a homogenous and high-grade activation. Further, no costly cooling apparatus is needed.

Abstract: PURPOSE:To increase the operating speed by a method wherein an opening is filled with a shielding film while impurities are fed to a base region, with the shielding film used as a mask, so that an external base region is reduced in resistance in a self-aligned manner. CONSTITUTION:A base region 12 is formed by feeding p-type impurities of low concentration to a principal face of a substrate 1. Etching, with a photoresist film 13 used as a mask, is done to form an opening 14 on respective parts of a silicon oxide film 9 and silicon nitride film 11 covering the principal face of the base region 12. After the photoresist film 13 is removed. n-type impurities of high concentration are fed to the principal face of the substrate 1 to form an emitter region 15 on a part of the base region 12 defined by the opening 14. Then, a shielding film 16 is deposited on the silicon nitride film 11. Subsequently by etching back the shielding film 16, the opening 14 on the emitter region 15 is filled with the shielding film 16. The shielding film 16 is used as a mask to feed p-type impurities to the principal face of the substrate 1. Thus a base region wherein the resistance is high immediately under the emitter region and the resistance is low in the vicinity of the emitter region can be obtained and the operating speed of a bipolar transistor can be increased.

Abstract: PURPOSE:To improve safety on the rupture of a weak point pin during the opening/closing operation of a vane by forming a gap between the weak point pin hole on an arm lever and a weak point pin, in a guide vane mechanism of a pump water wheel, etc. CONSTITUTION:A gap (g) is formed between a pin hole 15 on an arm lever 6 which constitutes a guide vane and a weak point pin 9. When a large load acts, the guide vane arm 5 and the arm lever 6 are jointed by the pin 9 until the pin 9 is broken, and after the pin 9 is broken, the guide vane arm 5 and the arm lever 6 are jointed by the frictional force of a frictional ring 10, and the free revolution of a guide vane spindle 2 over the gap (g) is prevented, and a large accident damage is prevented. Further, since the charged load is distinctly separated on the weak point pin 9 and the frictional ring 10, the designing of the charged load is drastically facilitated. When the outside diameter of an arm pressing plate 11 is made smaller than the inside diameter of the frictional ring 10, the readjustment of the frictional ring 10 is facilitated, when the weak point pin 9 is broken and replaced, and the adjusting stop time of a water wheel can be reduced.

Title: Water controller
Inventor: MIWA YOSHISHIGE
IPC: F23N1/08
Filed: 1982-11-26
Abstract: PURPOSE:To hold a discharge quantity of hot water constant even if the pressure of supplied water is varied, by providing connecting path which connects an auxiliary high pressure chamber to a high pressure chamber and providing an adjusting valve which interlockes with an auxiliary diaphragm to throttle this connecting path. CONSTITUTION:When a water cock 8 is throttled to reduce the discharge quantity of hot water, the differential pressure between a high pressure chamber 2 and the downstream of a Venturi tube 6 is reduced. Since the pressure in the high pressure chamber 2 rises when the water cock 8 is throttled, the pressure in an axuiliary high pressure chamber 24 rises through a connecting path 26, and an axuiliary diaphragm 33 is deformed to the side of an auxiliary low pressure chamber 25, and an adjusting valve 27 throttles a pressure control hole 28. Then, the differential pressure between the high pressure chamber 2 and the low pressure chamber 3 is increased to suppress the rise of pressure in the low pressure chamber 3, and consequently, a diaphragm 1 is deformed to the side of the low pressure chamber 3, and the adjusting valve throttles a valve 16. Therefore, even if the pressure of supplied water is varied thereafter, the quantity of water flowed to a heat exchanger 10 is held constant by the essential function of a water governor 5.
