Title: Ion implantation device
Inventor: TAYA TOSHIMICHI
IPC: H01L21/265
Filed: 1983-04-01
Abstract: PURPOSE:To enable the angle of ion implantation to be arbitrarily controlled by vacuum-resistantly connecting a vacuum duct to an implantation chamber and providing a mechanism for arbitrarily adjusting the angle of the implantation chamber relative to the incidence direction of an ion beam. CONSTITUTION:The implantation angle (theta) of a wafer 2 relative to an ion beam 1 is controlled by moving an implantation chamber 6 on a driving guide rail 31 using an implantation-angle-controlling driving shaft 9 as the center of the rotational movement. Since a vacuum duct 5 and the implantation chamber 6 are connected with a vacuum bellows 8, high vacuum is maintained even during the operation of the implantation chamber 6.

Title: Vehicle mounted acoustic device having moveable operation surface
Inventor: SUGANO SATORU
IPC: G11B33/02
Filed: 1994-02-28
Abstract: PURPOSE:To prevent the occurrence of a damage caused by the unnecessity of a moveable operation surface by changing the time duration between the time of discriminating the presence or the absence of a recording medium and the closure of the surface based on the ON/OFF detection result of a power supply. CONSTITUTION:When a means 3 detects the opening condition of the moveable operation surface, and a means 4 detects a condition in which no recording medium exists in the port of the surface, a closure drive means 5 of the surface is driven to close the surface. At that time, a power supply condition detection means 2 detects the ON/OFF condition of a power supply. If the power supply ON condition is detected, a means 6, which changes the closure time of the surface based on the power supply condition, sets a constant time to secure a necessary time to exchange cassette tapes. Thus, the surface is closed after a necessary and minimum time is passed and cumbersome operations are eliminated.

Title: Obstacle sensing device for unmanned vehicle
Inventor: MIYAKE AKIHIRO
IPC: G01W1/14
Filed: 1991-03-19
Abstract: PURPOSE:To achive smooth running of an unmanned vehicle by eliminating emergency stop of the vehicle as malfunction during running in the rain because of rain sensing of an ultrasonic sensor. CONSTITUTION:Then an ultrasonic sensor 10 senses ultrasonic waves while an unmanned transport vehicle M is running, a CPU 16 judges if any obstacle exists on the basis of the ultrasonic signal obtained. If at this time a precipitation quantity sensor 11 senses rain, the CPU 16 calculates the obstacle acknowledging time on the basis of resistance valve of the ultrasonic sensor 10. If ultrasonic signals continue intermittently within the obstacle acknowledging time, the fed ultrasonic waves are judged as due to rain - if the ultrasonic signals are constant within the obstacle acknowledging time, it is judged as a reflex wave due to ultrasonic wave incidence to an obstacle S. In the case ultrasonic waves due to rain are incoming, the CPU 16 allows the unmanned vehicle to continue running, and in the case reflex wave is incoming, the vehicle is put into emergency stop.

Abstract: PROBLEM TO BE SOLVED: To attain constant voltage control and sequence control of a multiple output circuit, by connecting the load side of a first switch element to a feedback control circuit and, through a second switch element, the power side of the first switch element to the feedback control circuit. SOLUTION: The voltage of first output L1 drives a switching transistor 2 by means of feedback control using a main control circuit 3 to attain constant voltage. The circuit of a second output L2 delays rising in the voltage of the second output L2 with an over-saturated reactor 4 inserted in series, and controls a sequence circuit 6 with a switch element 7 inserted in series to turn ON the switch element 7 only while the first output L1 is established. While the switch element 7 is turned OFF, a switch element 8 is turned ON to input the voltage of the second output L2 into a comparator 5 serving as a feedback circuit, thereby maintaining the voltage on the output side of the over saturated reactor 4 constant.

Abstract: PURPOSE:To eliminate transmission error by writing the data to be transmitted from a transmission side into a memory with the aid of synchronization of a transmission side clock, reading the data of the memory in parallel with the write operation with the aid of synchronization of a reception side clock, and sending out the data to the reception side. CONSTITUTION:Between a transmission side equipment 1 and a reception side equipment 2 to execute synchronous data transmission, a memory 5 is interposed so that the write operation and read operation of the data can be respectively independently executed, and the data SD to be sent out from the transmission side is written into the memory 5 and made tentatively resident there with the aid of synchronization of a transmission side clock ST. On the other hand, the data SD tentatively stagnated in the memory 5 is read out in parallel with the write operation while synchronizing a reception side clock RT and sent out to the reception side as reception side data RD. Therefore, the disturbance of synchronization of the transmission timing and reception timing of the data is relaxed by providing the time for making the data in transmission resident in the memory 5.

Abstract: PURPOSE:To obtain a means which can be limited once a day by comparing the day of the week of an existing timepiece unit with a fixed day stored in a day- of-the-week memory means, and executing a self-diagnosis program when no coincidence is obtained from said comparison. CONSTITUTION:The contents of a fixed day-of-the-week memory part 12 are defined as A; while the contents of a day-of-the-week register 43 are defined as B. Then a comparison part 13 is started by a power supply application detecting part 10 and compares input A and B with each other. When Anot equal to B is satisfied, a self-diagnosis program is executed. Then the contents A are set to the register 43. A self-holding action is performed with A=B and no change is produced even though the starting is fed from the part 10. The days of the week of a timepiece unit are changed every 24hr, and then the contents of the register 43 are also changed.

Title: Magnetic disk
Inventor: HAGA SHUICHI
IPC: G11B5/82
Filed: 1990-03-09
Abstract: PURPOSE:To improve the coercive force of a magnetic disk, to suppress noise, and to simplify the production process by successively laminating a metal film and a magnetic layer on a glass substrate which is preliminarily subjected to texturing treatment. CONSTITUTION:A metal film 2 and magnetic layer 3 are successively laminated on a glass substrate having a fine ruggedness on its surface formed by texturing treatment. By this constitution, the surface of the magnetic layer has also fine ruggedness due to the laminar effect of the lower layer and has improved squareness ratio due to dimensional magnetic anisotropy. Moreover, the coercive force is increased since a bias voltage is applied by the electric conductivity of the metal layer. Since the contact surface of the medium to a head is decreased, the coefft. of friction is reduced, which improves durability of the magnetic disk and raises realiability of the disk. Especially in a magnetic disk treated with chemical texturing, the surface of the glass substrate has egg-shape projections, which does not lose its intrinsic surface smoothness but reduces friction resistance. Thereby, the obtd. magnetic disk has high coercive force and low noise, and the production process of the disk is simplified.
