Title: Full-size image sensor circuit
Inventor: KOBATA MITSUHIRO
IPC: H01L27/146
Filed: 1987-07-23
Abstract: PURPOSE:To prevent the noise from appearing in an image signal output, by arranging capacitors of diode structure applying reversed phase pulses to pulse- type noise, at pulse-type noise generating part positions on driving circuits side. CONSTITUTION:Capacitors Cds of diode structure are connected between connection points of photo diodes PD1-PDn and drains of transistors Q1-Qn and a shift register 3 for driving, via inverters 2-1, 2-2. The capacitors Cds differentiate output pulses of the inverters, and apply reversed phase pulses with respect to the switching noise appearing at the connection points to these connection points. Thereby, the noise appearing at the connection points can be cancelled. Further, clock pulses CLK 1, CLK 2 are differentiated by the capacitor Cds of diode structure, and reversed phase pulses with respect to clock noise are applied to an image signal output VS. Thereby, the clock noise appearing in the image signal output VS can be cancelled.

Title: Semiconductor laser device
Inventor: MIHASHI YUTAKA
IPC: H01S5/00
Filed: 1983-10-03
Abstract: PURPOSE:To enable to stably oscillate with a low threshold value current by doping an impurity having deep impurity level in a current blocking layer to shorten the lifetime of the minority carrier. CONSTITUTION:A P type GaAs current blocking layer 2a dopes the prescribed density of impurity having deep impurity level to shorten the lifetime of the minority carrier. Electrons in the section corresponding to the layer 2a are collected once to the deep impurity level Ed, and the electrons and the holes are recombined. Therefore, they are recombined in a very short time as compared with the recombination of the electrons of direct transmission band and the holes of valency electron band. Accordingly, the lifetime of the minority carrier can be remarkably shortened by doping the impurity having the deep impurity level. Thus, the current blocking capacity is increased to reliably perform a current constriction operation, and stable oscillation can be performed with low threshold value current.

Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To facilitate teaching operation for a torch by making an operator move only the torch over a look at a work on CAD at teaching time. SOLUTION: An environment model operation part 3 inputs a torch model which has a torch-side fitting point shifted from the torch axis, a robot model which has a degree 6 of freedom, and a work model. Through a torch teaching data operation part 4, the operator moves the torch model to input and store torch angles at teaching points and torch-side fitting points. An automatic generation part 5 for robot teaching data calculates the angles of respective robot axes through inverse conversion from position attitudes at the torchside fitting points. When the torch fitting reference point of the robot 11 does not reach a torch-side fitting point or when the robot 11 causes interference, the torch is rotated by a specific angle on the torch axis and a check is made again; if there is no interference, the angles of the respective axes found through this operation are stored.  Then the operator properly corrects data on defective parts.
