Title: Optical radar for searching obstacle
Inventor: MATSUBA HIRONORI
IPC: G01S17/06
Filed: 1992-08-25
Abstract: PURPOSE:To obtain an optical radar for projecting a light beam toward an obstacle and then receiving a reflected light to search an obstacle in which an obstacle can be searched with excellent performance over a long distance by moving a light projecting source and a light receiving unit synchronously thereby making the light beam movable through a cheap and simple constitution. CONSTITUTION:A light projecting source 1 and a light receiving unit 6 are mounted on a same board and a light beam 3 is projected from the light source 1 through a lens 2 onto an obstacle 4. Light reflected on the obstacle 4 is received by the light receiving unit 6 and the obstacle 4 is searched based on an output signal from the light receiving unit 6. When the obstacle 4 is searched, the board mounting the light source 1 and the light receiving unit 6 is moved through an oscillator on the focal plane of the lens 2 at a predetermined period. This movement causes transition of the light beam 3 from upper obstacle 4 to lower obstacle thus allowing search of obstacle over a wide range.

Title: Output circuit
Inventor: ASANO MICHIO
IPC: H03K19/0175
Filed: 1985-11-08
Abstract: PURPOSE:To attain the transmission of signals at a high speed and at a low level of electric power by controlling the input signal supplied to an output transistor so that the signal amplitude of the 1st wave that can be made incident on a transmission line when the load is connected to an output terminal via the transmission line is equal to about 1/2 amplitude of the output signal obtained when the load is connected directly to the output terminal. CONSTITUTION:If a PMOS FET is finished so that the drain current higher than the typical value flows, the potential of the drain electrode of a PMOS FET 15 rises up together with the output potential of a differential amplifier 22. Thus the potential of the gate electrode of a PMOS FET 14 rises up and therefore the potential of the source electrode of the FET 14, i.e., the potential of the gate electrode of the FET 15 rises up and the drain current is reduced. When the gain of the amplifier 22 is sufficiently high, the feedback is carried out so that the potential of the forward input is approximately equal to that of the reverse input. As a result, the potential of the drain current of the FET 15 is kept at about VDD/2 and this drain current is controlled at a fixed level regardless of the variance of the corresponding FET characteristics.

Title: Manufacture of semiconductor device
Inventor: SHIMIZU NORIYOSHI
IPC: H01L21/203
Filed: 1990-09-18
Abstract: PURPOSE:To obtain the molecular-beam epitaxial method, for Si, which can obtain a desired impurity concentration distribution by a method wherein a P molecular-beam generation amount from a P molecular-beam generation apparatus is controlled on the basis of a P molecular-beam amount detected by using a detection apparatus and a P-doping amount in an Si growth layer is matched to a prescribed value. CONSTITUTION:When a P-doped Si layer is grown by using a molecular-beam epitaxial (MBE) operation, a required P concentration is input to an impurity concentration control apparatus 17. Then, a corresponding ion current value is set, InP is heated and a P molecular beam is generated at a constant speed. While the MBE operation progresses, an ion current generated at a quadrupole mass spectrograph system 16 is always compared with a set value; a heating current at a Knudsen cell 15 is increased or decreased so as to compensate its excess or deficiency. As P in the InP is consumed, it is required to gradually raise a cell temperature in order to realize a prescribed ion current value. By this invention, however, it is controlled so as to match a P molecular beam amount, and the state of source InP is not affected.

Abstract: PURPOSE:To simplify the data transfer processing by adding a memory check means to a numerical controller and a transmission data limiting means to a controller respectively. CONSTITUTION:A memory check means 5 is provided to a numerical controller 2 to check the idle state of an NC data memory 3 and at the same time to send back the permission information for data transmission including the reception enable data length information. While a transmission data limiting means 4 is provided to an FA controller 1 to transfer the NC data after limiting the quantity of this data less than the data length information. Thus the means 5 checks the idle state of the memory 3 and transfers data to the controller 1. These data are received by a transmission data limiting means 4, and the means 4 limits the NC data quantity so that the memory 3 has no overflow. Thus the indication is possible from the controller 2 for interruption and restart of the NC data transfer.
