Title: Seek device for optical disk
Inventor: WACHI SHIGEAKI
IPC: G11B27/10
Filed: 1988-12-12
Abstract: PURPOSE:To maximize a movement speed in the state where the movement load of a linear motor is lightest by integrating the output-side signal of a comparing means and varying the feedback quantity of speed information by the integral output. CONSTITUTION:When the error output of a comparing circuit 16 is increased, the terminal voltage of a capacitor G forming an integrating circuit 21 rises; and when the rise of the terminal voltage exceeds a prescribed range, a coefficient for multiplication is raised and the level of the speed signal outputted from a coefficient device 23 is raised to raise the transfer function of a feedback circuit. When the transfer function of the feedback circuit is raised, the follow-up capacity of a rough actuator 18 to a driving signal is improved; and when the driving signal accurately acquires a target track, the rough actuator 18 faithfully responds to this signal and is so controlled that the movement speed is zero on the target track.

Abstract: PURPOSE:To make a device compact and increase a clucth torque by providing cams for engaging a frictional clutch by a cam force and positioning the cams in a pilot clutch in radial direction and inside the pilot clutch in axial direction. CONSTITUTION:A cam 95 is composed of cam surfaces 93, 93 formed between a carrier 53 and a cam ring 75 and a ball 91 between these surfaces. When a pilot clutch 77 is engaged. a differential torque from a differential mechanism 45 is applied to the cams 95 to produce thrust forces 101 and 103 in right and left directions. A main clutch 63 is pressed against a differential case 25 to engage by a thrust force 101 through carriers 53 and 54 and shims 65. In this way, an engaging force of the main clutch 63 is added to that of the pilot clutch 77 to increase a differential limiting force of the differential mechanism 45. As for the thrust force 103, also a differential limiting force is strengthened in the same way as mentioned before. Since the cams 95 are positioned in the pilot clutch 77 in radial direction and inside the pilot clutch 77 in axial direction, the space can be saved and the device can be made compact.

Filed: 1986-12-27
Abstract: PURPOSE:To improve safety by preventing the drive of a vehicle loaded device unless a rider detecting means detects a rider, in a drive control device for the power window, etc., of a vehicle. CONSTITUTION:When an ignition switch is turned on, a power source unit 5 feeds a constant voltage VC to a CPU 1, a rider detecting unit 2, a 0.1-sec. timer 3, and an interface circuit 4. And, the CPU 1 operates the rider detecting unit 2 through the intrusion processing by means of the 0.1-sec. timer 3 to detect the existence of a rider on an FR seat. When a rider exists, the energizing/ unenergizing of a relay RL 1 is set in accordance with the operation of a switch WLSW, and a battery voltage is fed to a power source line. On the contrary, when there is no rider, the relay RL 1 is set to unenergizing, cutting off the feed of a battery voltage to the power source line. By this structure, the drive of a vehicle loaded device during the absence of a rider can be prevented, thereby improving safety.
