Patent JP-H02114536-A (JP)
Title: Semiconductor device and its application
Inventor: FUEDERIKO KAPATSUSO
IPC: H01L27/06
Filed: 1989-09-14
Abstract: PURPOSE: To make it possible to obtain a multitude of peak current-voltage characteristics in a semiconductor device by a method wherein a plurality of quantum wells are separated from each other so that an effective quantum mechanical interaction does not exist between the quantum mechanical states of the quantum wells and so that an etching of a resonance tunneling is generated by different base-emitter voltages during the operation of a transistor. CONSTITUTION: A semiconductor device is provided into such a structure that the device has at least two pieces of quantum wells and an etching of a resonance tunneling is generated by different base-emitter voltages through these quantum wells during the operation of a transistor. These two quantum wells are separated from each other so that there is not an effective quantum mechanical interaction between the quantum mechanical states of the quantum wells. This separation is conducted in such a way as to provide a low-band gap and doped thick layer between the quantum wells. Moreover, it is preferable that the value of the thickness of this separation layer is a value larger than the value of the thermal de Broglie wavelength of the material for the layer.  In such a way, a negative transfer conductance region is obtained in a collector current, which is flowed as a function of an emitter-base voltage, and when there are N pieces of the quantum wells, N pieces of peak current-voltage characteristics are obtained in transfer characteristics.

Title: Follow-up control system for robot having running axis
Inventor: HIDESHIMA KEIJI
IPC: G05B19/404
Filed: 1985-10-25
Abstract: PURPOSE:To prevent the deterioration of follow-up accuracy secured at the tip of a robot by defining the follow-up deviation between a running axis and a line as the robot deviation set in the direction of the running axis and control ling and correcting the joint axis of the robot main body. CONSTITUTION:A robot arithmetic part 2 calculates the shift angle of each axis of the robot main body from the follow-up deviation of the robot and also performs the deviation processing and the command calculation. Based on this command, a motor driver 3 for each axis drives each motor 4 of a robot main body driving part A. While a running axis arithmetic part 8 performs the calculation of shift amount of the drive shaft as well as the devia tion processing and the command calculation of the running axis. Based on this command, a motor driver 9 drives a motor 10 of a drive shaft driving part B. Thus the running axis performs the rough follow-up drive in response to the line average speed and the follow-up deviation obtained from said rough follow-up drive between the running axis shaft and a line is fed back to the robot main body and corrected by each axis of the robot in the form of a robot deviation of the component in the direction of the running axis.

Filed: 1989-09-13
Abstract: PURPOSE:To obtain the title material which can form a coating film having good gloss and excellent water repellency, stainproofness and durability when applied to a coated surface of various products, by using a reaction product of a metal alkoxide with a compound having reactive hydroxyl groups as effective component. CONSTITUTION:This material for treating a coated surface contains a reaction product of a metal alkoxide with a compound having reactive hydroxyl groups. There is no limitation on the compound having reactive hydroxyl groups; however, various alcohols, especially fluorinated alcohols, are preferably used. The metal alkoxide is not particularly limited, an example being a compound shown by the general formula M(OR)n (wherein M is a metal atom; R is a hydrocarbon group; (n) is a number equal to the valence of the metal atom M). The reaction of the metal alkoxide and the compound having reactive hydroxyl groups is effected by incorporating them into a solvent and heating the mixture to a temperature at which the compound having reactive hydroxyl groups can be dissolved in the solvent or a suitable temperature above it.

Filed: 1987-09-22
Abstract: PURPOSE:To effectively use an effective exposure region and cope with the tendency to increasing chip size, by making the configuration of the chip region for pattern formation into a hexagon or a polygon having more sides. CONSTITUTION:In an IC chip which is a polygon more than hexagon, when a chip pattern of an octagon is made in an effective exposure region on an IC chip shaped in a polygon having six or more sides, a region in which a pattern is formed the region for pattern formation is defined by an octagon which is made by the four sides of a straight line section showing the effective exposure region corresponding to the outlines of a reticule and by the remaining four sides made by connecting an effective exposure region by straight lines. As a result, the octagon except for not-used effective exposure regions 6 of crescent-shaped parts shown by slanting lines, becomes effective exposure region, with the result that the not-used effective exposure region 6 is considerably decreased and the enlargement of the IC chip is implemented. As a result, it is possible to effectively use the effective exposure region 6 and cape with the tendency to increasing chip size without causing the enlargement of the aperture of a reduced lens.

Title: Variable valve mechanism of internal combustion engine
Inventor: HIRAIWA KAZUMI
IPC: F01L13/00
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To make improvement in the control accuracy of valve on-off timing by installing a decenterable driving wheel in space between two camshafts, and engaging a drive piece installed on the circumference of this driving wheel with a connecting pin integrally installed in these respective camshafts. SOLUTION: If the turning center of a driving wheel 22 is accorded with that between both camshafts 10 and 12, this driving wheel 22 and these camshafts 10 and 12 are synchronously rotated together. When the driving wheel 22 is made to be eccentric in this state, a hole 40 of a drive piece 38 and a pin 42 transmit a rotation as sliding, but the camshaft 10 rotated varying its angular velocity. In brief, a distance up to the drive piece 38 from a turning center of the camshaft 10 is varied together with the rotation, whereas a distance up to the drive piece 38 from the turning center of the driving wheel 22 is constant. With this constitution, since each phase the rotational directions of those of pins 42, 44 and 60 differs, their timing varying in each angular velocity is changed.
