Title: Schottky diode and its manufacture
Inventor: RAJESH KUMAR
IPC: H01L29/872
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a Schottky diode in which a Schottky barrier in a reverse directional bias is high and the Schottky barrier in a forward directional bias is low. SOLUTION: An n- type layer 3 composed of 3C-SiC having a band gap smaller than that of an n- type epitaxial layer 2 is provided on an upper face of the n- type epitaxial layer 2 composed of 4H-SiC or 6H-SiC, also a trench part 4 passing the n- type layer 3 and reaching the n- type epitaxial layer 2 is provided, and an Al film 5 is brought in Schottky contact with the n- type layer 3 and the n- type epitaxial layer 2. With such a structure, at reverse bias, the contact part of the n- type layer 2 with the Al film 5 in a mesa part is pinched off by a depletion layer which extends to the n- type epitaxial layer 2, and at reverse bias, the potential barrier in the mesa part is made higher. Thus, in a reverse directed bias, the potential barrier can be made high in the n- type epitaxial layer 2, and in a forward directed bias, the potential barrier can be lowered in the n- type layer 3.  Then, it is possible to realize reduction in the consumption power of a Schottky diode.

Title: Gate pulse generating circuit
Inventor: TANAKA TOSHIAKI
IPC: H04N5/18
Filed: 1988-08-31
Abstract: PURPOSE:To obtain a stable gate pulse by inputting a flyback pulse from a flyback transformer to a base of a transistor(TR) via the 1st differentiating circuit, coupling the 2nd differentiating circuit with the output so as to clamp any of positive or negative output waveform. CONSTITUTION:A flyback pulse inputted from an input terminal 1 passes through a resistor R1 and differentiated by the 1st differentiating circuit comprising components C1 and R2 and fed to a base of a TR Q1. The collector potential of the TR Q1 forms a collector waveform of a rectangular wave pulse. The pulse signal formed in this way is outputted from the 2nd differentiating circuit comprising a capacitor C2 and a resistor R4 and a diode D1 cancels a pulse in opposite direction equivalent to a negative pulse and applies peak clamp. Since the output signal waveform is synchronized with the back porch of a composite video signal, the signal is extracted as a gate pulse from an output terminal 4.

Title: Zinc-bromine battery
Inventor: HASHIMOTO TAKASHI
IPC: H01M12/08
Filed: 1982-12-16
Abstract: PURPOSE:To enhance the current efficiency of a zinc-bromine battery by preventing bromine contained in electrolyte from performing self-discharge on contacting with zinc deposited over the negative electrode by introducing electrolyte moved into an anolyte chamber into a bromine-removing device to decrease the concentration of bromine in electrolyte before it is fed back to a catholyte container. CONSTITUTION:Before charging and discharging of a battery 1 are carried out, current is fed to a bromine-removing device 21 by means of an auxiliary power source 39 to deposit zinc over a negative electrode 26 by electrodeposition. Bromine molecule generated on a positive electrode 25 is diffused into an anolyte container 9 through conductors 33 and 35. After that, when the cell 1 is driven by moving electrolyte toward the positive electrode according difference between the outputs of pumps 11 and 12 representing difference between the pressures of anolyte 7 and catholyte 8, electrolyte which has moved from a cathodic chamber 3 into an anodic chamber 2 through a diaphragm 4 is introduced into the anolyte container 9 through a conductor 36 increasing the liquid level of the anolyte 7. Following that, the anolyte 7 flows into the cathodic chamber 23 of the bormine-removing device 21 through a conductor 36 due to the difference in the liquid level thereby causing bromine contained in the anolyte 7 and zinc deposited over the negative electrode 26 to perform self-discharge before electrolyte of low bromine concentration is introduced into a catholyte container 10 through a conductor 34. As a result, operation of high current efficiency can be carried out by feeding back electrolyte of low bromine concentration.

Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a high speed CT scanner capable of identifying a specific target substance without forming a complete reconstruction of CT image by preliminarily selecting baggages. SOLUTION: A CT scanner 120 is provided with a rotary plateform 125. This rotary platform 125, which is provided with an X-ray source 128 and a detector array 130, forms a plural number of projections of baggages 112 passing through the platform 125.
