Title: Electro-optical device
Inventor: TAKEUCHI ATSUSHI
IPC: G02F1/03
Filed: 1988-08-05
Abstract: PURPOSE:To easily confirm a metallic wiring by visual observation, to quickly and exactly align a light beam used for sampling an electric signal and to prevent the generation of an unnecessary current, while using a dielectric multilayer film mirror for showing a smaller reflection factor by providing an insulating layer on a semicon ductor substrate. CONSTITUTION:The title device consists of an insulating layer 2 formed on a semicon ductor substrate 1, a metallic wiring 3 formed on the insulating layer 2, a dielectric multilayer film mirror formed on the metallic wiring 3 and an electro-optical crystal 5 formed on the dielectric multilayer film mirror 4. Since the insulating layer 2 is provided newly, a reflection factor of the dielectric multilayer film mirror 4 can be lowered, and a light beam can be aligned very easily. Therefore, the light beam can be aligned quickly in an arbitrary position of the metallic wiring 3, and a transmission light excites an electron and a hole in the semiconductor substrate 1 since the reflection factor is lowered, but since the metallic wiring 3 and the semiconductor substrate 1 are insulated by the insulating layer 2, the generation of an unnecessary current can be suppressed. In such a way, an electro-optical device which prevents the genera tion of an unnecessary current, while using the dielectric multilayer film mirror 4 for showing a small reflection factor is obtained.

Title: Occupancy releasing control system for shared disk device
Inventor: ARAKI TOMOE
IPC: G06F3/06
Filed: 1988-08-04
Abstract: PURPOSE:To prevent a file, etc., on a shared disk device from being destructed by occupying the shared disk device with a self-system over the execution section of plural channel programs. CONSTITUTION:The title system provides a shared disk device occupying starting means 104 to bury and execute an occupied channel command to a channel program corresponding to the input/output request by adding an input/output request for a shared disk device 103 when the contents of the occupied counter is an initial value and occupy the shared disk device with the self-system. Consequently, while an one logical unit updating is executed, the shared disk device can be occupied by the self-system and even when the input/output request is an error, the shared disk device can be occupied until the error restoration processing is completed. Thus, while one logical unit is updated, the possibility that the input/output request from other type system is interrupted can be prevented, and when the input/output request is the one to request the updating for the same file, the destruction of the file can be prevented.

Title: Tracking error signal generator
Inventor: SUZUKI TOSHIO
IPC: G11B7/095
Filed: 1990-07-24
Abstract: PURPOSE:To obtain a proper tracking error signal by delaying a second pulse signal supplied to a clear terminal CL by a delay circuit. CONSTITUTION:The second pulse signal supplied to the clear terminal CL is delayed by delay circuits 51 and 52 even with respect to a D type flip flop which has a difference between the delay time from the rise of the input signal of the clock terminal CK to the rise of the output terminal Q and the delay time from the rise of the input signal of the clear terminal CL to the rise of the output terminal Q. Consequently, the occurrence of a blind sector is prevented to detect the phase difference when respective input signals of the clock terminal CK and the clear terminal CL scarcely have the phase difference. Thus, the proper tracking error signal is obtained.
