Patent JP-H03274820-A (JP)
Title: Semiconductor device
Inventor: YAMANISHI YUJI
IPC: H03K17/10
Filed: 1990-03-23
Abstract: PURPOSE:To surely ignite at an igniter circuit by providing plural groups in which plural transistors are formed, arranging them on a semiconductor substrate alternately, and connecting all the transistors in parallel with a power source. CONSTITUTION:The group A7 and the group B8 of two pairs of MOSFETs are arranged on the semiconductor substrate 6 alternately. The group A7 is equipped with three MOSFETs and the group B8 with four MOSFETs. At the initial stage, the MOSFETs of both the groups A and B are operated, however, when a current value arrives at a value (Io) by which constant current control is applied, the operation of the MOSFET of the group A is stopped, and only that of the MOSFET of the group B is performed. Therefore, since no current larger than the current value Io flows on the MOSFET of an operating group B, a constant current flows. Then, all the MOSFETs are stopped at a time to. In such a way, heat generation in a chip can be uniformalized, thereby, local heat generation can be prevented.

Title: Special effect waveform generator
Inventor: IDESHITA NORIHIKO
IPC: H04N5/265
Filed: 1979-06-12
Abstract: PURPOSE:To realize the smooth shift of the effect screen without increasing the arithmetic velocity but by carrying out the selection of several delay circuits provided at the input route of the clock pulse via the lower-rank bit of the output of the A/D converter. CONSTITUTION:Both delay circuit 20 and selection circuit 21 are inserted to the route of the clock pulse from horizontal higher harmonic generating circuit 4'. Circuit 20 consists of delay line 22 of about 62ns, delay line 23 of about 124ns and delay line 24 of about 186ns each; and these lines are selected according to the state of the lower-rank bit and through circuit 21. Circuit 21 comprises four switches 25-28 plus decoder 29. Decoder 29 receives two lower-rank bits among the output of A/D converter 16 and then changes over switches 25-28. The clock pulse sent from circuit 21 is supplied to horizontal digital arithmetic circuit 2 to decide the arithmetic timing. The cycle is kept at 1/256H and shifts in the 62ns-step with interlocking of the pulses sent from circuit 21 lathough the shift of the horizontal reset pulse is set to 62ns. As a result, the special effect basic wave which shifts with the horizontal reset pulse can be obtained at the output of circuit 2.

Abstract: PURPOSE:To prevent unexpected conduction of corresponding first and second contacts by partitioning each switch region of a membrane switch with a web formed in a spacer. CONSTITUTION:A membrane switch 10 contains a lower membrane, a spacer 12, and an upper membrane, which are stacked in order. The spacer 12 has a cut-off part 12a which houses the whole switch regions 14-17. Webs 12b-12d of the spacer 12 partition between the switch region 14 and 15, 15 and 16, and 16 and 17. The almost all part of the surrounding of each of the switches 14-17 is covered with the spacer 12.

Title: Liquid crystal display element
Inventor: OKUMURA OSAMU
IPC: G02F1/133
Filed: 1990-03-24
Abstract: PURPOSE:To make a display bright and prevent the display from being viewed double by using such liquid crystal that light which is incident on a liquid crystal cell and reaches a reflecting plate center a almost linear polarized state. CONSTITUTION:Various conditions of the liquid crystal cell are determined so that the light which is incident on the liquid crystal cell 1 and reaches the reflecting plate 4 becomes linear polarized light. The incident light is polarized linearly by a polarizing plate 2 and generally changes into elliptic polarized light while having a phase difference because of the birefringence of liquid crystal molecules. The light becomes linear polarized light when reaching the reflecting plate. On the return path where the light travels while reflected, the light travels having exactly the same polarization change with that on the going path to become the original linear polarized light again, so that the light can passes through the polarizing plate without any loss of the quantity of light. Consequently, the display is bright, coloring is small, and the display is prevented from being viewed double.

Title: Pressure controller
Inventor: TANAHASHI TAKASHI
IPC: F16K31/06
Filed: 1979-06-12
Abstract: PURPOSE: To prevent vibrations due to the pressure of a fluid and the mass of a valve and plunger, by suppressing the sudden motion of the valve through the operation of a dashpot.  
     CONSTITUTION: Once fed with a current, coil 8 generates force pressing plunger 7 down. This action pushes valve 4 via push rod 13 and rod 6. The pressure of a fluid flowing out via outlet 2 depends upon the force operating on valve body 4. Damper room (a) operates as what is called a viscous resistance element suppressing the sudden motion of valve 4. Namely, the sudden motion of valve 4, i.e. the sudden motion of diaphragm 5 generates positive or negative pressure to the atmospheric pressure in damper room (a) and the pressure operates on disphragm 5 in the opposite direction to its motion direction at any time.

Title: Magnetic recording and reproducing device
Inventor: KAWACHI TOSHIHITO
IPC: G11B15/60
Filed: 1984-04-13
Abstract: PURPOSE:To obtain an excellent tape running characteristic with less damage of a tape even under very humid atmosphere by coating a thin layer made of nitride, carbide, carbide and nitride, oxide or nitride and oxide to a magnetic tape sliding face. CONSTITUTION:For example, a tension post 15 and tilt posts 17, 23 among components in a tape running system are formed by coating a thin layer made of a nitride, a carbide, a carbide/nitride, an oxide or an oxide/nitride to an outer circumferential face (tape sliding face) of a mother material made of stainless steel by means of the laser beam vapor deposition method. Thus, the thin film formed in this way is a dense and smooth film and the Vickers hardness is >=2,000. Since the surface film with a large hardness is formed in this way, even if the tape winding angle is large, the friction coefficient around the drum is less and the wear and damage to both the drum and tape are very less.

IPC: G03G15/04
Filed: 1985-04-09
Abstract: PURPOSE:To print out at high speed in the case of a small printing width by respectively individually connecting extension lines to common side electrodes of respective chips, scanning only chip groups corresponding to the printing width and enlarging a rotating speed of a photosensitive body in inverse proportion to the printing width. CONSTITUTION:When a pulse voltage is impressed to extension lines COM1-COM4 in a time sharing, and only chips 21-24 are scanned, a scanning time T' once may be T' (<a fixed scanning time T). Accordingly, when forming one line by a minimum printing width, a high speed printing out can be performed. When one scanning time is shortened, line intervals of respective latent images I1-I4 formed on a photosensitive drum 7 become smaller than a prescribed line interval L. A control section 10 outputs a speed control signal to a motor drive circuit 14 in order to drive a stepping motor at high speed. Accordingly, since the rotating speed of the photosensitive drum 7 is increased in inverse proportion to the printing width, on the photosensitive drum 7, the latent images I1-I4 are successively formed at the prescribed line interval L.
