Title: Communication controller
Inventor: MATSUOKA TOSHIYA
IPC: G06F13/00
Filed: 1985-03-15
Abstract: PURPOSE:To shorten a time from start of instruction of starting transmission until a data transmission is actually started by performing a DMA transfer to a buffer memory and a previous processing of the transmission in parallel. CONSTITUTION:When an address of a data length of a transmitting data stored in a memory are designated by a communication control device according to an input and output command, an input and output command decoding circuit 1 decodes them and instructs DMA transfer circuit 3 to be activated to transfer through a signal line 2. At the same time, by an input and output command, a start of the transmission is instructed, so that the input and output command circuit 1 decodes it and instructs a transmission pretreatment circuit 5 to activate through a signal line 5. The transmission pre-treatment circuit 5 waits for an information of a completion of the DMA transfer of the DMA transfer circuit 3fed after the DMA transfer through a signal line 15 and instructs a transmitting circuit 7 to activate to transmit through a signal line 6. Thus, the transmitting circuit 7 starts to transmit a data to a communication line.

Title: Method for driving pedal solenoid
Inventor: NARITA HIROSHI
IPC: G10F1/02
Filed: 1991-03-18
Abstract: PURPOSE:To reduce the collision sound of a pedal by simple solenoid driving control and to improve the sharpness of a pedal. CONSTITUTION:When a pedal releasing command is inputted (time t1) in the depressed state of a damper pedal, power supply to the solenoid is stopped for a period T1 and then electric power E2 larger than electric power E1 required for holding the depressed state is supplied to the solenoid for a period T2 to damp the pedal. The timing (time t2) of the damping is the time when the lifted pedal arrives at a position X on which a pedal effect disappears. Power supply to the solenoid is stopped again from time t3 to move the pedal up to the uppermost position.

Title: Semiconductor integratd circuit device
Inventor: MIZUKAMI MASAO
IPC: H01L29/78
Filed: 1980-04-23
Abstract: PURPOSE:To eliminate the variation in a well potential due to the capacitive connection to a signal line in a semiconductor integrated circuit device by forming the same conductivity type and higher impurity density buried region as a well region and than the well region at the bottom of the well region. CONSTITUTION:A high impurity density P<+> type buried region 11 is formed in an N type Si substrate 10. A low impurity density P type well region 12 is formed on the surface of the substrate 10, and an N-channel MOSFET QN and a P-channel MOSFET QP are formed adjacent to one another. Electrodes and wires necessary to form an inverter circuit are formed in the FETs QN and QP. Since the region 11 is thus formed, the impedance of the region 12 is low, and a sufficient substrate potential is supplied from a P<+> type contact region through the region 11 to the substrate corresponding part of the FET QN. Accordingly, it can reduce the variation in the well potential due to the capacitive connection or the like to the signal line and stabilize the threshold voltage characteristics of the FET QN.

Title: Inspection of strength of conductor pattern
Inventor: MIYAWAKI NOBUHIKO
IPC: G01N19/04
Filed: 1990-03-05
Abstract: PURPOSE:To evaluate the adhesion strength of a conductor pattern by jetting liquid on the main surface of a substrate on which the conductor pattern is formed at a specified pressure, and changing the shape of the conductor pattern with the fluid. CONSTITUTION:Many green sheets which are formed of alumina as a main raw material are laminated and burned in a hydrogen furnace filled with moisture added atmosphere. Thus a multilayered ceramic plate 1a is obtained. An IC package 1 which is a body under inspection comprises the multilayered ceramic plate 1a. The thin films of Ti, Mo and Cu are sequentially formed on the main surface of the substrate 1a by sputtering. Then Cu is plated. Thereafter, finishing plating is performed with Ni and Au. Thus a wiring pattern 2 is formed. In the strength inspection of the pattern 2, high-pressure water is jetted through a nozzle 3 with a water jet device. The nozzle 3 is rotated and moved along the specified orbit on the main surface of the substrate 1a. Shock is applied on the wiring pattern 2 with the high-pressure water. When the adhesion strength of the wiring pattern 2 is insufficient at this time, film peeling and film floating occur, and the defective part is detected.

IPC: F16J15/16
Filed: 1991-02-27
Abstract: PURPOSE:To reduce the friction resistance and abrasion of a seal bush by reducing the area of a sealing surface which is pressed by the pressure of a fluid to be delivered. CONSTITUTION:Sealing portions 23, 24 for sealing the space between inner and outer peripheral surfaces 3, 4 are disposed on both sides of the direction of a rotary axis with ports 5, 7 (6, 8) therebetween, and the sealing portions are integrally joined to each other by a web 25. A communicating hole 26 is formed through the web 25. Forces with which the pressure of a fluid to be delivered between the ports 5, 7 (6, 8) pushes the sealing portions 23, 24 in different directions becomes internal forces because of the presence of the web 25 and are canceled out between the ports 5, 7. Therefore, no thrust is applied to a seal bush 21(22) and, since there is no necessity of a receiver in the thrust direction, the friction resistance and abrasion of the seal bush can be reduced.

Title: Manufacture of magnetic recording medium
Inventor: OOUCHI HIROBUMI
IPC: H01F41/18
Filed: 1984-03-23
Abstract: PURPOSE:To obtain the magnetic recording medium of a gamma-Fe2O3 thin film having excellent magnetic characteristics with high productivity by forming an Fe3O4 thin film with a magnetron sputtering system while heating a substrate. CONSTITUTION:A magnetic field is generated on the surface of a target by a permanent magnet 12, and electrons are trapped to generate high-density plasma in the vicinity of the target. Consequently, the film-forming velocity is increased, and the bombardment of the electrons against the target is reduced to control an increase in temps. of the substrate. Meanwhile, although the crystallization temp. (about 200 deg.C) is necessary for obtaining a good-quality Fe3O4 thin film, the temp. of the substrate is low in a magnetron sputtering system. Accordingly, the temp. of the substrate is elevated by a heater 13 for heating the substrate to about 180-300 deg.C which is higher than the crystallization temp. of Fe3O4.
