Title: Evaluating method for extrinsic gettering capacity of silicon wafer
Inventor: NAKASHIZU TSUNEO
IPC: H01L21/66
Filed: 1992-04-07
Abstract: PURPOSE:To evaluate an impurity gettering capacity of defects intentionally formed on the rear side of a wafer in order to reduce the impurities of the wafer. CONSTITUTION:A specified amount of Ni (10<12> to 10<14> atoms/cm<2>) is built up on the surface of a P type silicon wafer as a detection wafer. The wafer is heat-treated at a temperature of 900 deg.C and over and less than 1200 deg.C. The amount of N deposited on the surface is divided with the amount of N built up on the surface. This divided value is used to evaluate extrinsic gettering capacity. This construction makes it possible to evaluate only the extrinsic gettering capacity and develop extrinsic gettering wafers which are excellent in their gettering capacity.

Abstract: PURPOSE: To remove and recover the ammonium compound efficiently as well as economically by decomposing by heating the coal ash containing the ammonium compound caught by a dust collector at a specific temp. in a decomposition furnace utilizing a combustion waste gas.  
     CONSTITUTION: In treating an exhaust gas from a coal combusting boiler 1 in a system comprising a high dust type denitration-air preheating-low temp. dust collection-desulfurization, the coal ash containing the ammonium compound caught by the dust collector is pneumatically transported and thrown into the decomposition furnace 11 of the ammonium compound.

Title: Driving circuit
Inventor: ANTON FUORERU
IPC: H05B39/02
Filed: 1989-05-02
Abstract: PURPOSE: To prevent the breakage of a drive transistor resulting from the large short-circuit current of a drive circuit by detecting a short-circuit based on only voltage comparison. CONSTITUTION: A drive circuit is equipped with an RC circuit which is composed of resistor R1 one side of which is connected to an earth terminal and a capacitor C which is in series therewith and one side of which is connected to the positive terminal of a supply voltage source, a comparator 38 which supplies a blocking signal against a power transistor T5 to an output when the voltage of the resistor R1 is further negative than the voltage of a collector after comparing the voltage of the resistor R1 of the RC circuit with the voltage of the collector of the power transistor T5, and a limiting element T4 which limits the voltage of the resistor R1 of the RC circuit to the value of a higher value than the saturation value of the power transistor T5.  Thereby, since the voltage extracted from an operation voltage is compared, the temporary voltage peak of the operation voltage has no influence on the disconnection of the power transistor as long as the voltage is not so large as causing the breakage of the power transistor.

Title: Optical modulator and demodulator
Inventor: TSUJII KOUICHI
IPC: H03M5/16
Filed: 1981-07-20
Abstract: PURPOSE:To perform the transmission and reception of data without receiving any effect of the level fluctuation of an optical system, by converting a transmission data into binary data and then transmitting the binary data simultaneously with a carrier which received modulation in luminance. CONSTITUTION:The transmitter side has rise and fall detecting circuits 1 and 2 plus positive and negative polarity pulse generating circuits 3 and 4. Thus the rise and fall are detected for a data signal SD and made to correspond to the level of binary data which transmits the pulse to be converted into the positive and negative polarity pulses. With these pulses, the luminance is modulated for a light emitting element 7 which transmits an optical signal of a certain level in the form of a carrier. While a carrier detecting circuit 17 is provided at the receiver side to convert the optical signal transmitted thrugh an optical fiber into an electric signal. This electric signal is converted into binary data when it is higher than a prescribed level. Thus both the transmission data and the carrier can be transmitted at one time at the transmitter side, and the receiver side can receive with high stability the transmission data although the level of an optical system has a change.

Title: Wide input range dc stabilized power supply
Inventor: WATANABE ICHIU
IPC: H02M3/28
Filed: 1978-09-20
Abstract: PURPOSE: To increase the allowable range of input voltage in a DC stabilized power supply by forming DC stabilized power supply by utilizing the nonlinearity of the converting characteristics of a DC-DC converter.  
     CONSTITUTION: An error amplifier AMP amplifies the difference between the output voltage Eo of a converter and a standard voltage VR, and a pulse duration converter PWM converts the amplified output from the amplifier AMP to duty signal D to negatively feed back it to the base of a transistor Q so as to coincide the output voltage Eo to standard value VR. The conversion ratio of a DC-DC converter is decreased or increased in response to the increase or decrease of the input voltage E 1  since negatively fed back to retain the output voltage Eo constant. When the input voltage E 1  is varied widely, the conversion ratio must be largely altered in the converter to maintain the output voltage Eo constant, however the conversion ratio can be largely changed by varying the duty dignal D slightly. Accordingly, it can provide a wide input voltage E 1  stabilized power supply.
