Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a heterojunction bipolar transistor that is capable of being used for mobile radio communications, by heat treating at a specified temperature range after growing a semiconductor layer on a base layer after the base has been grown. SOLUTION: A heterojunction bipolar transistor(HBT) in which a carbon- doped GaAs layer is used for the base layer, is made by growing epitaxially an n-type collector-contact layer, an n-type GaAs collector layer, an p-type GaAs base layer, an n-type emitter layer, and an n-type GaAs emitter-contact layer, sequentially on a semi-insulating GaAs substrate by an MOCVD method. If the obtained wafer is heat treated in nitrogen ambient at a temperature ranging from 500 to 670 deg.C, variation rate of the current gain becomes smaller than 1.1. The heat treatment condition, with which the initial current gain after the heat treatment does not degrade to a level lower than the initial current gain of an HBT that is not subjected to the heat treatment, is a heat treatment temperature ranging from 520 deg.C to 650 deg.C and heat treatment time of 2 minutes.

Title: First in first out storage device
Inventor: TSUGI HIDEKI
IPC: G11C7/00
Filed: 1992-09-01
Abstract: PURPOSE:To structure a first in first out storage device for (m) word by using the two port RAM of the (m) word. CONSTITUTION:The output value of an adder 4 and the output value of a read counter 2 are compared by a comparator 6. After a signal indicating these two values coincide is outputted from the comparator 6, and at the rise of the write signal WR, a signal FULL is outputted by a flip flop 8 indicating the RAM 3 is full. The output of a write counter 1 and that of the read counter 2 are compared by a comparator 5. When a signal from the comparator 5 indicating these two output values coincide and a signal/Q from the flip flop 8 indicating the RAM 3 is not full are inputted, a signal EMPTY is outputted from an OR gate 9 indicating the RAM 3 is empty. Thus, the capacity of the two port RAM of the (m) word is used without wasting it.

Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To protect privacy of a video image, while keeping the operability of an image pickup device and a monitor system. SOLUTION: In this video signal processor, a mask pulse position setting means 5 sets an area whose privacy is to be protected. A mask pulse generating means 6 generates a mask pulse corresponding to the privacy protection area of a video image outputted from an image pickup device. The mask pulse controls a video signal changeover means 3 to select a video signal from a mask use video signal generating means 1 so as to mask the video signal. The privacy protection area may also be changed in tracing with a zoom magnification and a panning/tilt position. Operability is satisfactory, because this video signal processor does not place limitations on the panning/tilt operation of a motor drive universal head. By masking only the privacy protection area, privacy without limiting the entire screen can be protected.

Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To obtain a logic analyzer in which trigger conditions can be set including the history of variation of the signal to be measured, e.g. the number of times when specified conditions are satisfied. SOLUTION: An operator sets pretrigger conditions combining AND conditions and OR conditions, and the number of times to be matched with the pretrigger conditions at a trigger condition setting section 15. A programmable logic array 16 comprises a sequential logic circuit, e.g. a flip-flop circuit, as well as an AND circuit and an OR circuit and the interconnection can be set and modified electrically and arbitrarily. The trigger condition setting section 15 forms a logic circuit outputting a trigger signal 17 by modifying the interconnection in programmable logic array 16 when the trigger conditions being set by the operator are satisfied. Since a circuit element, e.g. a flip-flop circuit, can store the state, intricate trigger conditions including the history of variation of the signal to be measured can be set.
