Patent JP-S6136946-A (JP)
Title: Semiconductor device
Inventor: EBINA MASAKI
IPC: H01L27/08
Filed: 1984-07-30
Abstract: PURPOSE:To prevent the generation of a latch-up by surrounding four sides of a P channel transistor by an N<+> layer and those of an N channel transistor by a P<+> layer and connecting the N<+> layer to a power supply line and the P<+> layer to a grounding line at a large number of positions in an output buffer section for a CMOS-IC. CONSTITUTION:In an output buffer section for a CMOS-IC, four sides of an N channel transistor 15 are surrounded by a P<+> layer 16, and the P<+> layer is connected to grounding line 27 at a large number of positions. Four sides are sur- rounded by an N<+> layer connected to a power supply line 32 at a large number of positions in a P channel transistor 23. Consequently, impedance 28 between the grounding line 27 and a P<+> layer 30 is reduced, thus rapidly sucking up substrate currents 26, 31 to the grounding line 27 from the P<+> layer 30, then preventing the generation of a latch-up. Currents intending to flow into a parasitic transistor 29 through a parasitic transistor 35 are also erased by currents 50 flowing through the N<+> layer 24 from the power supply line 32, thus further obviating the generation of the latch-up.

Filed: 1988-06-30
Abstract: PURPOSE:To prevent the displayed picture on a display device from disappearing even in the middle of transmitting and receiving and to offer a device to be very usable by supplying data read from a memory to the display except for the time of executing the access of a CPU. CONSTITUTION:When an image-picked up image signal is stored to an image memory 14, the image signal is read, and it is supplied through a multiplexer 13 and a multiplexer 8 to a D/A converting circuit 9. The signal is converted to an analog signal by the D/A converting circuit 9, supplied through a synchronization synthesizing circuit 10 and output processing circuit 11 to a display device 12 and displayed. At such a time, the changeover of the multiplexers is controlled by a changeover signal generated from an image memory bus control circuit 19 based on a signal supplied from an operating part 7 and a CPU 18. An operator displays the necessary image on the display device 12, thereafter, operates the transmission switch of the operating part 7 and transmits the displayed image to an opponent side. At such a time, since the image signal is switched by the multiplexer, it is not displayed on the display device 12 under transmission.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To accurately form a low concn. layer at only the drain even for a short gate length by self-alignedly forming lightly doped drain(LDD) regions, without mask alignment. SOLUTION: A gate material 9 is etched by the anisotropic etching using an etchant which removes this material 9 but a first layer 8 to leave the material 9 at only the flank of the first layer 8 which is then etched off to result in a gate electrode 10 having a sectional shape vertical at the drain side and curved at the source side.

Title: Controlling method of acceleration and deceleration of motor
Inventor: HAYAMIZU TSUKASA
IPC: H02P8/14
Filed: 1978-12-25
Abstract: PURPOSE:To establish arbitral accelerating and decelerating loci freely by driving a motor by reading out a bit-pattern stored in a memory; and by selecting a frequency of clock pulses which scan the memory depending on the amount of variations. CONSTITUTION:A driving-pulse train, which can obtain desired operational loci at the time of acceleration and deceleration, is preliminarily stored in a memory 2 as a bit pattern. The addresses are scanned by an address counter 5, and read-out pulses are given to a driving circuit 1, and a motor M is operated at every very-small-unit amount of variations. If amount of variation larger than that of the driving-pulse train is required, address scanning is made by a clock pulse CP1; and if smaller amount of variation is required, scanning is made at a frequency higher than the clock pulse CP1 by giving a time-axis-shrinking rate instruction. Therefore the acceleration and deceleration loci of the motor can be freely selected, their changes can be accomplished very easily, and operability can be enhanced.
