Title: Schottky junction structure
Inventor: HIROSE KAZUYUKI
IPC: H01L21/338
Filed: 1988-01-14
Abstract: PURPOSE:To make it possible to control the height of Schottky barrier by shaping a kind of metal having a large chemical combination energy with III-V compound semiconductor in a specified thickness before forming another kind of metal on the surface of III-V compound semiconductor. CONSTITUTION:Between metal 3 and III-V compound semiconductor 1, another kind of metal 2 having a large chemical combination energy with the semiconductor 1 is formed as thick as a 1/10-30atoms thick layer. Consequently, the strong chemical combination between the metal 2 and the semiconductor assures a sharp and stable interface. As a result, development of defects in the semiconductor 1 which is regarded to cause pinning of Fermi level is restrained and, therefore, the Schottky barrier is not a definite value but decided based on work function of the metal 2. The height of the Schottky barrier of the semiconductor 1 can be thereby controlled.

Title: Auto focusing device
Inventor: OSAWA TOSHIFUMI
IPC: G03B13/36
Filed: 1986-01-18
Abstract: PURPOSE:To maintain integration time within a prescribed range by providing signal amplifying means which amplify two kinds of output signals of photodetecting means by the gains changed according to the result of the discrimination by a discriminating means and output the same to a synchronous detection means. CONSTITUTION:Integration is executed until a voltage VA+B attains a reference voltage Vref and the voltage VTH preset by resistors R7, R8. The attainment of the voltage VA+B at the voltage VTH is detected by a comparator CP. A binary counter 15 is provided to detect the excessively short or long integration time. A judgement control circuit 1 reads the level of the signal Tmin at that point of the time. The circuit outputs gain decrease signals to gain selecting circuits 11, 12 by judging that the integration time is too short if the level is low. The control circuit, outputs gain increase signals to the circuits 11, 12 by judging that the integration time is too long if the signal Tmax. attains the high level before the output of the comparator CP attains the high level. The integration action is thus corrected again.

Abstract: PURPOSE:To realize an unmanned operation for a car on a designated course, by detecting a course guide tape stuck to the travelling course and a position display tape stuck to the floor surface with an image sensor attached to the bottom surface of the unmanned car. CONSTITUTION:An image sensor 4 attached to an unmanned car 1 detects a course guide tape or various types of position tapes stuck to the floor surface and reads the contents of signals. For example, if a course station 2-3 is designated with a home station 2-1 defined as a start position, the car 1 travels continuously in a low speed until the sensor 4 does not detect a tape 2-12 of a speed reduction range within the station 2-1 and then travels in a high speed. The car 1 travels straight at a branch point (a), turns right at a branch point (b) with the right tape defined as a course guide tape and goes into an area of the station 2-3 in the course B. When the tape 2-12 is detected, the car 1 is switched to the travelling of a low speed. Then the sensor 4 detects a stop region 2-13, and the car 1 is damped and stopped by a mechanical brake.

Abstract: PROBLEM TO BE SOLVED: To effectively prevent the middle of an intermediate band from axially shifting to a tire forming drum. SOLUTION: The axially middle part of an intermediate band 12 locating between bead cores 18 is kept on being attracted and held with a permanent magnet 32 at the locking of the bead cores 18 from radially inside through the diametrically expanding bead locking bodies 17. Thus, even when the axial tensile force is given to the intermediate band 12 due to the difference between the diametrically expanding speed of a pair of the bead locking bodies 17, the axial displacement of the intermediate band 1 is restricted from occurring by means of the attracting holding force caused by the permanent magnet 32.
