Abstract: PURPOSE:To improve the efficiency of a system without reducing the data recording capacity of the recording medium by setting a prescribed track among plural tracks as a management information recording tracks, and recording here the attribute of necessary data for processing while corresponding to an information unit with a discrimination mark. CONSTITUTION:The prescribed track, for instance a first track, among the plural tracks of an optical card 11 is set as the management information recording track 15, and the other tracks are set as data recording tracks, and prescribed pre-record marks 16 are formed leaving intervals beforehand on the control information recording track 15, while corresponding to the information unit of the data to be recorded on the data recording track. Then, at every time when the data is written on the data recording track, a laser write mark 17 indicating the attribute of the write data, is recorded on a part where the pre-record mark 16 corresponding to the write position of the said data is recorded. Thus, the recording/reproducing of the data can be executed efficiently with a low cost without reducing the data recording capacity.

Title: Three-dimensional radar apparatus
Inventor: SHINONAGA MITSUYOSHI
IPC: G01S7/02
Filed: 1993-02-12
Abstract: PURPOSE:To provide a three-dimensional radar apparatus which can enhance the accuracy of the direction of a target. CONSTITUTION:The reception output of a one-dimensional array 111 is subjected to a series of detecting processes, thereby to detect the position of a target. The distance data is taken out. Meanwhile, a receiving signal of each antenna element obtained by the one-dimensional array 111 is formed into data and stored at least for one PRI time. The receiving data corresponding to the distance is taken out by use of the target distance data obtained at the detecting processes. Each receiving data is processed by a coherent signal treatment to suppress unnecessary signal components, and then, sent to an angle measuring/operating circuit 19. The angle is thus measured/operated. In this case, since only the receiving data when the target is detected is input to the measuring/ operating circuit 19, a wasteful operation is eliminated even when a highly accurate angle measuring/operating algorithm is applied. Accordingly, the angle of elevation can be detected efficiently in a small-size constitution.

Filed: 1978-03-03
Abstract: PURPOSE: To eliminate unstableness at the time of selective switching of a TV camera, by erasing a picture on a picture tube in a synchronous pull-in period.  
     CONSTITUTION: In a period when switch unit 3 is selecting TV camera 1, vertical oscillation circuit 7 is perfectly in a synchronous oscillation state and phase comparator circuit 11 sends out a phase coincidence signal to hold switch unit 10 ON; a video signal from input buffer circuit 5 reaches picture tube 9 via video amplifier circuit 8 and is scanned by a vertical deflecting signal from circuit 7, so that it will be reproduced on picture tube 9 as an image. Through the switching of switch unit 3, TV camera 1 is changed over to TV camera 2 with a synchronizing-signal generating method independent of TV camera 1 and, in consequence, the phase of the vertical synchronizing signal is difference. For the purpose, switch unit 10 is made OFF temporarily by the phase difference signal of circuit 11 so as to prevent an image from appearing on picture tube 9. After circuit 7 completes acquisition of synchronism and circuit 11 sends out the phase coincidence signal, switch unit 10 is turned ON again to reproduce the video signal of TV camera 2 on picture tube 9.

Filed: 1979-03-02
Abstract: PURPOSE:To provide a zener diode having high reliability by implanting ion into low density layer forming an emitter junction to form maximum low density portion in depth at 0.2mu from the surface of a substrate. CONSTITUTION:An n-type epitaxial layer 2 is laminated on a p-type silicon substrate 1, and separated via a p-type layer 3, and sequentially diffused to form a p<->-type layer 5 and an n-type layer 6 thereon. An insulating film 4 is perforated with opening to expose an emitter junction je, and B ion is implanted at predetermined voltage. Then, a protective film 8 is coated thereon, and annealed. The B ion is gauss distributed around the center of mean depth responsive to the acceleration voltage in depth direction. The drop voltage of the emitter junction is almost determined by the value of the p<+>-type density in the p<->-type layer 5, and the potential for occurring a zener breakdown is almost determined by the mean depth. When the mean depth is selected to higher than 0.2mu, the instability of the breakdown voltage due to protracted test in high temperature atmosphere is eliminated to provide a constant-voltage diode having high reliability without almost ageing change of breakdown voltage.

Title: Magnetic tape device
Inventor: SAITO FUMINARI
IPC: G11B15/665
Filed: 1985-02-12
Abstract: PURPOSE:To detect accurately the position of a magnetic tape without separating the tape from a fixed magnetic head when a drive mode is changed, by actuating the 1st tape path forming means in response to the 2nd tape path forming means including a tape lead-out post. CONSTITUTION:When a cam gear 30 is revolved up to a revolving angle corresponding to a stop mode, a switch is actuated to stop the drive of a motor. Thus the 2nd tape path is formed. Here a tape lead-out pin 17 leads a magnetic tape 2 out of a cassette 1 to secure a stable contact between the tape 2 and a fixed magnetic head 16 at a larger contact angle than that obtained in the record/reproduction mode. An arm 26 is held stably with the counterclockwise force of a spring 27 and a contact between a projected part 29 and a pressure cam 37. Then a switch is actuated with push of a fast wind button, and the tape path drives the tape 2 at a high speed by a reel drive mechanism. The tape drive is usually unstable in a high-speed drive mode compared with the record/reproduction mode. Here the tape 2 has a large contact area with the head 16 by means of the pin 17 and therefore the stable detection of signals is secured even in the high-speed drive mode.

Title: Controller for vehicle with transmission
Inventor: KASHIWABARA MASUO
IPC: F16H61/10
Filed: 1995-02-14
Abstract: PURPOSE: To control a (transmission) gear ratio in a variable manner even if the inclination changes by exercising such a control as the greater the slope is, the nearer the gear ratio becomes to a gear ratio, which is set by a high- output-running-mode-gear-ratio setting means, because when going upward, the greater the inclination of a slope is, the higher the power required is. CONSTITUTION: With respect to the gear shift pressure and the line pressure, they are adjusted by controlling the oil pressure in a hydraulic circuit 6 by means of solenoid valves 7, 8, while the solenoid valves 7, 8 are controlled by a controller 9. Accordingly, the gear ratio can be controlled by controlling the gear shift pressure and the line pressure. In order to control the gear ratio, detection signals from a car speed sensor 10, a throttle sensor 11, and an engine speed sensor 12 are inputted into the controller 9. In addition, a mode switch 13, which switches the characteristics of upper limit value on the higher-car- speed-side of the gear ratio between a low fuel cost traveling mode and a high power traveling mode, is prepared, and the result is inputted into the controller 9. Based on these signals, the controller 9 controls the solenoid valves 7, 8 so as to obtain a target, gear ratio for the sake of speed change control.
