Title: Method of junction for semiconductor substrate
Inventor: TANZAWA KATSUJIRO
IPC: H01L21/18
Filed: 1986-10-08
Abstract: PURPOSE:To reduce the percentage of rejects by a method wherein, after microwaves have been made to irradiate at least on one of two semiconductor substrates, the mirror faces of the substrates are brought into contact with each other without interposition of foreign matters between them, and the two substrates are formed into one body by performing a heat treatment. CONSTITUTION:Microwaves are made to irradiate at least on one of two semi conductor substrates. Subsequently, the two mirror-polished faces of the semicon ductor substrates are contacted without interposition of foreign matters, and the two semiconductor substrates are formed in one body. As the excessive moisture on the adhesion surface is decomposed and vanished by the irradiation of microwaves, the generation of voids on the heat treatment temperature region can be prevented and the percentage of rejects can be lowered. Besides, as the degeneration of interface due to excessive moisture can be prevented, the electric characteristics of the interface can also be improved remarkably.

Title: Four-wheel steering device
Inventor: INOUE HIDEAKI
IPC: B62D137/00
Filed: 1991-09-18
Abstract: PURPOSE:To develop straight traveling stability increasing function by steering angle control in a condition in which it is adopted more to a vehicle steering by a driver by setting a steering angle control operation area by the use of a vehicle behavior with the steering speed of front wheels added in addition to front wheel steering angle. CONSTITUTION:A four-wheel steering device is provided with a front wheel steering angle detecting means, a front wheel steering speed detecting means, and a vehicle behavior detecting means. Based on the detected signals, a steering angle of a vehicle to be controlled is set by a vehicle steering angle setting means and, based on the set steering angle, a wheel is steered by a steering means. Also, in steering angle control based on vehicle behavior, for example, yaw rate, switchover control is made by a switchover means to control the steering angle by using output from the vehicle behavior detecting means when both the front wheel steering angle and front wheel steering speed are below a specified limit. Then a target steering angle is determined and, based on that angle, the wheels are steered. Thus stability of the vehicle behavior can be maintained even when the vehicle travels on roads on which curves are continued right and left alternately.

Title: Electrophotographic sensitive body
Inventor: KOYAMA TAKASHI
IPC: G03G5/14
Filed: 1988-09-23
Abstract: PURPOSE:To obtain potential characteristics and superior images stabilized in all the environmental conditions from low temperature and low humidity to high temperature and high humidity by adding a small amount of salts to a resin interlayer. CONSTITUTION:The interlayer contains a resin component and at least one kind of salt selected from fluoroborates, thiocyanates, nitrates, and halides as additives in an amount of 1 - 2,000ppm per the resin comonent.

Title: Method of driving semiconductor memory
Inventor: KOTAKE YOSHINORI
IPC: G11C16/06
Filed: 1994-10-03
Abstract: PURPOSE: To obtain a method which allows the reading of memory contents of a NOR type non-volatile memory with a lower voltage and a lower power consumption. CONSTITUTION: Source wires S1-Sm are arranged parallel with word wires W1-Wm with respect to a memory array where NOR type non-volatile memory cells (T11)-(Tmn) are arranged in a matrix. When memory contents of the memory cells are read out, potentials of bit wires B1-Bn are set lower than that of a selected source wire. By this method, the lowering of the threshold voltage of the memory cells attributed to a drain voltage of a transistor is checked to prevent erroneous reading owing to action of a non-selection memory cell. This also eliminates charging or discharging by reading memory cells arranged on a common word wire in a batch thereby enabling the lowering of power consumption and further allows the expanding of the margin of variations in the threshold voltage of the memory cells.

Abstract: PURPOSE:To easily manufacture an optical bistable circuit by constituting a negative resistance circuit of a tunnel diode series circuit in which plural pieces of tunnel diodes are connected in series in the same direction to each other. CONSTITUTION:The title circuit has the same constitution as a conventional optical bistable circuit excluding a fact that a negative resistance circuit consists of a tunnel diode series circuit in which plural (n) pieces of tunnel diodes TD1, TD2...TDn are connected in series in the same direction to each other.
