Title: Method of designing arrangement of integrated circuit
Inventor: TANAKA MIYAKO
IPC: H01L21/82
Filed: 1987-04-17
Abstract: PURPOSE:To avoid the occurrence of an unfinished wiring by ensuring a region inhibiting arrangement of functional cell in a functional cell region, changing the former region into a wiring region and disposing functional cells again when functional cells are concentrated and wirings are crowded. CONSTITUTION:When functional cells 25 are concentrated, wirings are crowded and a wiring between a terminal 27 and a terminal 28 is not completed in a region 24, a region such as one 26 is used as an arrangement inhibition region for the functional cells. When the arrangement inhibition region is varied into a wiring region and the arrangement of the functional cells and wirings are designed again, a wiring 29 can be drawn because the ensured arrangement inhibition region 26 is employed as the wiring region. When an unfinished wiring is generated around the region 24 as the result of such arrangement design, a region in the vicinity of the region 24 is added and used as the arrangement inhibition region and changed into a wiring region, and the arrangement of the functional cells and wirings are executed again. Accordingly, the local crowdedness of the wirings is removed, thus avoiding unfinished wirings.

Title: Drive circuit for brushless motor
Inventor: FUKUSHIMA YASUHIRO
IPC: H02P6/06
Filed: 1995-03-28
Abstract: PURPOSE: To realize a stabilized circuit by employing an emitter follower connection with a coil through combination of a load element and an NPN transistor thereby reducing loss in the transistor. CONSTITUTION: When the terminal of a predrive IC 1, which is not connected with a load resistor 2, goes Low the base potential of a predrive PNP transistor 20 goes Low and the transistor 20 is turned ON. Consequently, the collector potential of the transistor 20 approaches the potential of a power supply VM and a base current begins to flow gradually in a transistor 21. Since a collector current flows gradually from the collector to the emitter of the transistor 20, a slight voltage drop appears across a load resistor 26. In other words, the base potential is increased with respect to the emitter potential as the collector current increases and thereby the base current increases thus suppressing loss in the output transistor 21.

Title: Termination control circuit
Inventor: MASUDA HIROO
IPC: G06F12/00
Filed: 1994-05-09
Abstract: PURPOSE:To perform such impedance processing that can reduce the waveform distortions at the termination part of a signal line. CONSTITUTION:A transmission line 3 is connected to an electronic circuit 1 which outputs the digital or analog signals and the line 3 transmits the signals. A distortion detecting part 7 detects the voltage waveform distortions at a termination part 5 of the line 3 in a signal transmission state. Then a distortion analyzing part 8 analyzes the detected waveform distortions, and a control signal generating part 9 generates a control signal based on the analyzing results of the part 8. Thus a variable resistance part 11 is controlled by the control signal, and the impedance is changed at the part 5 of the line 3 so as not to cause the waveform distortions.

Title: Precedence controlling device
Inventor: SUGAYA RITSUO
IPC: G06F12/02
Filed: 1984-05-11
Abstract: PURPOSE:To reduce the loss cycle in operand supply, by providing a means which stops the operand supply when a destructive overlap is detected. CONSTITUTION:Operands designated for every instruction by a variable-length operand instruction are supplied in such order as the process at an arithmetic section becomes easier. When the termination of the operand supply of the variable-length operand instruction is detected by a precedence controlling section, the operand supply of the succeeding instruction is immediately executed. When a destructive overlap of operands occurs, the overlap is detected by an overlap detecting means 202 and it is informed to the arithmetic section that the operand supply is disable at the precedence controlling section. As a result, the operand supply can be switched to that of the arithmetic section with a less loss cycle, since the prefetch of the precedence controlling section is stopped.

Title: Semiconductor device
Inventor: WADA YOSHIKI
IPC: H01L29/80
Filed: 1985-05-02
Abstract: PURPOSE:To increase the drain withstanding voltage, by specifying the distance from the planar surface for forming an alloy electrode to the hetero-interface being a boundary of a two-dimensional electron gas layer. CONSTITUTION:The thickness between the hetero-interface 8'' and the planar surface 15 for forming an alloy electrode is, for example, 0.12mum. Accordingly, the interface being a leading end of the alloy electrode reaches the depth of the AlGaAs layer 4 but does not reach the GaAs layer being an operating layer 9'', and thus the higher drain withstanding voltage can be attained as compared with prior arts. Although the thickness above 0.1mum between the hetero-interface and planar surface is required, it is preferably about 0.4mum because the larger thickness much spaces the two-dimensional electron gas layer to increase the series resistance. Thus the drain withstanding voltage can be increased without directly contacting the two-dimensional electron gas layer with the alloy electrode such as the drain.

Title: Deflecting circuit of image pickup tube
Inventor: NAKAMURA TAKASHI
IPC: H04N3/16
Filed: 1980-07-11
Abstract: PURPOSE:To eliminate scan distortion such as beam curvature by scanning a peripheral part outside of a normal scan area in a video blanking period and by making the gradient of a deflecting voltage waveform in scanning greater than that in normal scanning. CONSTITUTION:The periods T4 of horizontal deflecting voltages VH+ and VH- are effective scanning ones in a frame, and periods T2 the flyback periods of a beam. Then, the periods T1 and T2 are overscanning periods, and voltages in the overscanning periods T1 and T3 and flyback period T3 slant more steeply than in the normal scanning period T4. Consequently, the scanning speed of the beam increases, so the overscanning is achieved by a sufficiently long distance in short times T1 and T3.
