Title: Optical information recording disk
Inventor: GOTO AKIRA
IPC: G11B7/2433
Filed: 1986-09-19
Abstract: PURPOSE:To obtain an optical information recording medium provided with satisfactory recording sensitivity by forming a substrate of a material having >=110 deg.C heat resistance and <=4kcal/m.h. deg.C heat conductivity. CONSTITUTION:The substrate 1 is formed of the material having >=110 deg.C heat resistance and <=4kcal/m.h. deg.C heat conductivity. The use of a laser for recording having 8-10mW laser power on the film surface is thereby permitted and the optical information recording medium having a satisfactory recording sensitivity is provided. The generation of thermal deformation on the transfer surface of a signal pattern is obviated in spite of repeated projection of the laser for reproduction; therefore, the lifetime of the medium is improved to a greater extent. Since there is no need for any heat insulating layer at the boundary between the transfer surface of the signal pattern and the recording film, an easily producible and inexpensive optical information recording medium is provided.

Title: Correction circuit for delay of transmission frame
Inventor: YAMASHIRO TAKASHI
IPC: H04L12/52
Filed: 1983-11-22
Abstract: PURPOSE:To attain correction through a simple circuit even with a tansmission frame which is transmitted at a high speed by writing the data on a buffer circuit which holds the data on a converter to a prescribed memory with a transfer pulse which is generated by the prescribed logical conditions defined by a timing control pulse and a slot pulse. CONSTITUTION:In case a slot end pulse SLE is produced in a reading period of the read/write timing TRW, the data D on the j-th slot is held within a converter 9 by the pulse SLE. Then the data D is transferred to a buffer 10 with the timing of a write request WREQ which is delivered at the end of the reading period and held there. A timing circuit 8 produces a memory write pulse MW and writes the data BD of the buffer 10 to a memory. In the same way, the circuit 8 produces the pulse MW and writes the data DB of the buffer 10 also in case the pulse SLE is produced in a low period of the timing TRW.

Title: Brush turning gear
Inventor: TSUZUKI SHIGENORI
IPC: B24D13/10
Filed: 1990-08-22
Abstract: PURPOSE:To heighten the extent of noise control by accelerating a rotating velocity in a brush turning round the axial center of a brush shaft, while decelerating a revolving velocity in another brush turning round the axial center of a rotary casing. CONSTITUTION:Driving force of a motor 4 is transmitted to a planetary gear mechanism 51 via sun gears 32, 33 of a main shaft 3, therefore if the motor 4 is turned at high speed, a rotating velocity in a brush 5 becomes accelerated. In addition, the driving force of the motor 4 is transmitted to a rotary casing 2 after being decelerated via a continuously variable transmission 8, and thereby rotational speed of the rotary casing 2 becomes decelerated. Consequently, a revolving speed in the brush 5 can be slowed as accelerating the rotating velocity of the brush 5.

IPC: H05K1/18
Filed: 1991-09-03
Abstract: PURPOSE:To offer a power semiconductor device of high noise margin which includes a power chip and the control circuit parts on the same substrate. CONSTITUTION:The thickness D of a substrate insulating layer 1b in a control circuit parts mounting region in a metal insulation substrate 1 is composed thicker than the thickness (d) of a power chip mounting region to a semiconductor device made up by distributing and mounting the power chip 2 and the electronic parts 3 constituting its control circuit on a substrate having a metal insulating substrate 1 as a circuit substrate. Then, as to capacitance between a metal base 1a having the insulating layer of the substrate as a dielectric and a conductor pattern 1c, capacitance of a mounting region of the control circuit parts is made smaller than capacitance of the mounting region of the power chip. Thereby, a pulse current flowing through the control circuit caused by a foreign noise is reduced so as to improve noise margin.

Title: Driving method for liquid crystal display device
Inventor: SENOO YUTAKA
IPC: G02F1/133
Filed: 1986-09-19
Abstract: PURPOSE:To improve contrast and to obtain many gradations by setting the width of gate pulses applied to a gate line longer than a one-line writing time and setting the rising timing of the gate pulses before the writing time. CONSTITUTION:A drain signal is inverted at intervals of one field to drive a liquid crystal TV. When the pulse of the (j+1)th gate turns on, a TFT turns on at the (j)th writing time Wj and a picture element electrode 3 is charged through a TFT connected to the (j+1)th gate with a video signal of last timing so that the charging rate is 80%. Then while the gate of this TFT is on, an advance to the next timing Wj+1 is made and a signal which is inputted originally to the line is applied, but the charging rate is 80% for the original signal eventually while the gate is on, so 2X0.8=1.6V is obtained and the charging is carried out to only an about 0.4V potential difference. Consequently, channel width is shortened to reduce parasitic capacity and prevent liquid crystal from deteriorating, improve the contrast, and realize many gradations.
