Title: Disk loading controlling device
Inventor: OSAKI KIYOSHI
IPC: G11B17/035
Filed: 1993-08-16
Abstract: PURPOSE:To load two kinds of disks at specified positions by allowing a central sensor to detect them when large and small diameter disks are set on inserted positions, allowing either of the central, right or left sensors to detect them when they are shifted right or left, and driving and controlling them in a disk drawing-in direction by a transfer mechanism. CONSTITUTION:When a small diameter disk D2 is transferred in the disk drawing-in direction by a transfer roller 15, it is identified to be a small diameter disk by left and right sensors 42 and 43. When a large diameter disk D1 is moved by the roller 15, it is identified to be a large diameter disk by left and right sensors 44 and 45. When both sensors 44 and 45 are operated, an actuator 34a is switched to a sucking position and when one of the sensors 44 and 45 is not operated, a solenoid 34 is controlled by a controlling section so that the actuator 34a is on a projecting position. When a transfer operation of the disk D1 and D2 advances and they reach the vicinity of the upper part of a turntable 20, left and right deviation of the disks D1 and D2 is corrected and the disks D1 and D2 are made to align with a central line by left and right positioning pins 35 and 36, a transfer motor 14 is stopped by a controlling section 56 and the disks D1 and D2 are accurately positioned.

Title: Laminated capacitor
Inventor: OSADA HIRONARI
IPC: H01G4/33
Filed: 1989-08-31
Abstract: PURPOSE:To obtain a relatively compact capacitor having a large capacitance by using SiO2 which has the equivalent or higher electric characteristics as those of mica as a dielectric material and can be formed in a thin film readily, and laminating the SiO2. CONSTITUTION:A dielectric thin film 2 comprising SiO2 is formed on one surface of a dielectric substrate 1. A plurality of thin film capacitors on which electrodes 3 are imparted are laminated on the other surface of the substrate and on the surface of the dielectric thin film 2. When the SiO2 thin film 2 which is the dielectric is formed in this way, the thickness can be controlled within a range of 0.05-2mum. Therefore, the capacitance of the single-plate SiO2 capacitor can be made large even if the dielectric constant of the SiO2 is as small as about 4. Thus the capacitor having the equivalent or higher capacitance as that of a capacitor having the large number of liminated layers can be obtained with the capacitor having the less number of the laminated layers.

Abstract: PURPOSE:To obtain a system with high reliability in which a node processor supervises itself by supervising an input signal and an output signal of the node processor with simple hardware independently of the transmission and receiving section of node processor. CONSTITUTION:A receiving go-ahead (GA) detector 12 supervises always an input signal 6, and when a GA is detected, it is informed to a failure detector 15, and then a timer 14 is started.

A transmission GA detector 13 supervises always an output signal 7, and when a GA is detected in the output signal 7, it is informed to the failure detector 15 to stop the timer 14. In this case, the failure detector 15 regards it as normal when the timer 14 is in operation, and when the timer 14 is stopped already, it is regarded that the transmission section 9 transmits a GA without receiving the GA and a failure of the generation of GA is informed to the control section 10.

Title: Torque sensor
Inventor: NAKAMURA YOSHINOBU
IPC: G01L3/10
Filed: 1988-09-07
Abstract: PURPOSE:To reduce an output detection exciting current value and to enhance torque detection accuracy by providing a torque transmission shaft, a magnetic metal thin strip and a detection magnetic core. CONSTITUTION:When torque is applied to a torque transmission shaft 11, the strain stress corresponding to said torque acts on the shaft 1 and the magnetic characteristics of magnetic metal thin strips 12, 13 are changed. At this time, in such a case that the directions of magnetic fields are same, the effect of mutual interference is increased and torque detection accuracy is lowered. At this time, when the thin strips 12, 13 are constituted by splicing a plurality of unit magnetic metal thin strips from the aspect of dimensional restriction, the effect of mutual interference becomes large as the number of joints increase. When the interval between a group of detection magnetic cores 14a - 14d and a group of detection magnetic cores 15a - 15d is narrow and there is possibility such that both groups interfere with each other, exciting coils are differentially connected at every pair and detection coils are cumulatively connected at every pair to make the magnetic field directions of the respective groups of the magnetic cores 14a - 14d and 15a - 15d reverse. By this method, an output detection exciting current value can be reduced.
