Patent JP-S54157480-A (JP)
Title: Power transistor
Inventor: ITOU MITSUO
IPC: H01L29/08
Filed: 1978-06-02
Abstract: PURPOSE: To prevent the short-circuit between the emitter and the base for the transistor containing the emitter region featuring the comb-line plane shape on the surface of the base region by providing the reverse conducting region the bottom part of which reaches the base region at the comb-line root part.  
     CONSTITUTION: N - -type layer 2 is formed on N + -type Si substrate 1, and P-type base layer 3 is formed by diffusion to layer 2.  Then comb-line N-type floating region 4a plus N-type emitter region 4b enclosed by region 4a are formed by diffusion within layer 3 in order to insert ballast resistance RBB 1  into the base side. After this, P-type division region 5 for formation of the ballast resistance is formed is formed by diffusion so that the bottom part may touch base region 3 with partial division of region 4b in order to form ballat resistance RBB 2  at the emitter side. In such way, the emitter current detours at divided region M due to existence of region 5, and the voltage drop increases as the current increases.  As a result, the current concentration reduction effect is enhanced to increase the safe active region.

Title: Grid self-routing switch circuit system
Inventor: OGINO OSAO
Filed: 1988-03-22
Abstract: PURPOSE:To improve the property of high speed and reliability by arranging switch elements connected with packet processors in a bidirectional way into a square grid shape and connecting the switch elements with each other up and down and right and left with a bidirectional links into a loop shape. CONSTITUTION:A packet processor PPU to house an input/output line and execute processing for replacing a packet header, rejecting an erroneous packet, etc., and one switch element SE are connected in both directions with the link. Respective SEs are arranged into the square grid shape and connected up and down and right and left with each other with the bidirectional links into the loop shape. Addresses are added to respective PPUs, and each PPU adds the address of a destination PPU to the packet as the header of the packet when the PPU transfers the packet to the SE. The transfer of the packet from the PPU to house an input line at which the packet arrives to the PPU to house an output line to send the packet is executed by deciding which SE out of an upper SE, an lower SE, a right SE, and a left SE is to be used as the SE through which the packet is transferred based on the header information of the packet. The packet is transferred by switching the packet at each decided SE.

Title: Repeater system and relay method using the system
Inventor: TSUBONE NOBUHIRO
IPC: H04L12/26
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To suppress traffic between a repeater system and each server by observing the passing packet information on the repeater system with respect to the servers and outputting a server packet corresponding to the address that is changed, based on the result of the observation when a packet having the representative address is inputted. SOLUTION: The servers 4-1 to 4-n having individual IP addresses 5-1 to 5-n form a servers group 7, having a representative IP address 16. The group 7 is connected to clients 8-1 to 8-m, via the networks 2 and 3 and a repeater system 70. A server communication state monitoring part 71 of the system 70 decides the communication state of each server, based on the total number of IP packets which are outputted from the servers 4-1 to 4-n and passed through the system 70. When the packet having the address 16 is inputted from a client, the address 16 is changed into an individual IP address, based on the result of the decision. Then the inputted packet is outputted to the server that corresponds to the IP address.

Title: Liquid crystal display device
Inventor: KUNITO HIROBUMI
IPC: G09F9/30
Filed: 1989-03-20
Abstract: PURPOSE:To make retension volume large, to prolong the life of liquid crystal and to reduce the sticking of a liquid crystal display screen and the occurrence of unevenness in black by arranging a transparent picture element electrode so that it may overlap both a part where a gate signal line horizontally extends and a part where it vertically branches and constituting a retension volume element of the parts where the picture element electrode overlaps. CONSTITUTION:The gate signal line GL which horizontally extends has the part where it branches in a vertical direction every picture element. The transparent picture element electrode ITO 1 is arranged so as to overlap both the part where the gate signal line GL horizontally extends and the part where it vertically branches and the retension volume element Cadd 1 is constituted of the parts where the electrode ITO 1 overlaps. Therefore, the retension volume is made large and the value of DC component applied to the liquid crystal is made small because the effect of the change of the potential of a gate electrode on the potential of a picture element electrode is reduced at the time of switching a thin film transistor TFT. Thus, the retension volume is made large and the value of the DC component applied to the liquid crystal is made small, so that the life of the liquid crystal is prolonged and the sticking of the liquid crystal display screen and the occurrence of the unevenness in black are reduced.

Title: Variable frequency oscillator of surface acoustic wave
Inventor: URABE SHIYUUJI
IPC: H03B5/32
Filed: 1982-04-22
Abstract: PURPOSE:To eliminate the need for a variable resistor and to attain miniaturization, by amplifying each output of a surface acoustic wave element outputting plural phase outputs at a variable gain amplifier, synthesizing the outputs at a synthetic element and feeding back the outputs to an input electrode of the surface acoustic wave element. CONSTITUTION:The surface acoustic wave excited at the input electrode 2a is converted into electric signals at two output electrodes 2b, 2c. Since the output electrodes 2b, 2c are placed at a location shifted with each other in the propagating direction of the surface acoustic wave, output signals B, C of different phase are outputted from the output electrodes 2a and 2c. Taking the wavelength of the surface wave at the operating center frequency as lambda, and the shift of location of the output electrodes 2b, 2c as mlambda+lambda/4 (where m=0, 1, 2,...), the phase difference alpha is 90 deg.. The phase of the output signal of the synthetic element 6 is changed by changing the gain of the variable gain amplifiers 4, 5. Thus, the oscillating frequency of the oscillators is made variable.

Filed: 1993-03-25
Abstract: PURPOSE:To expand the margin against defects and waveform jumps on an optical disk and to reduce the rate of error occurrences by without depending on the light pattern of the disk to determine the AC center of an AC coupling but, using the center of resynchronization signals. CONSTITUTION:The input terminal of a buffer circuit 5 is connected to a prescribed reference potential REF during a resynchronization by an analog switch 4 which is driven by the signal that indicates a resynchronization position from a resynchronization position gate generating circuit 3. Thus, a bias point is determined for the input of the circuit 5 when the switch 4 is turned on. When it is turned off, the condition is held as is. As a result, the AC center of the output of the circuit 5 is set to the center of the resynchronization signals by the continuous on off operations of the switch 4. Therefore, the output of a comparator 6 makes no malfunction even though there exists noise.
