Title: Data processor
Inventor: SEKI MORIHARU
IPC: G06F1/24
Filed: 1990-09-10
Abstract: PURPOSE:To realize a simple and inexpensive power save function by adding a reset control circuit for receiving a reset control signal through a control port from a CPU and setting a reset signal supplied to a co-processor to an effective/ineffective state. CONSTITUTION:In the case a co-processor 2 is unnecessary, a CPU 1 makes a chip select signal supplied to the co-processor 2 through a control port 3 ineffective, and also, makes a reset control signal to the co-processor 2 effective. Also, in the case the co-processor 2 is necessary, the reset signal is made ineffective, and the chip select signal is made effective. Subsequently, when the received control signal becomes effective by a reset control circuit 8, the reset signal to the co-processor 2 is made effective immediately, and when the reset control signal becomes ineffective, the reset signal to the co-processor 2 is made ineffective by synchronizing with an internal clock signal of the CPU 1. In such a way, power save of the co-processor 2 can be realized without using a signal cut-off circuit, or without stopping temporarily an operation of the CPU 1.

Abstract: PURPOSE: To enable applications, especially for the phase control of lock signal at a synchronizer. CONSTITUTION: This time constant circuit is provided with plural number of transfer gates G0, G1...Gn composed of MOS transistors, while composing resistance elements of the drain-source paths. Since the capacity of this circuit is the structural capacity of MOS transistors, by selectively making the transfer gates (RE0, RE1...REn), time constants can be controlled. In order to keep the fixed value of capacity, auxiliary compensation circuits GC0, GC1...GCn are added to the respective transfer gates G0, G1...Gn. When these gates are made active, capacitors C0, C1...Cn at the same values as the capacitances of conducted gates are introduced. Furthermore, this time constant circuit is provided to a delay circuit which uses it.

Title: Disk sticking method
Inventor: TAMURA YUTAKA
IPC: G11B7/24015
Filed: 1989-09-14
Abstract: PURPOSE:To prevent distortion from being generated by executing fixed adhesion in an inner peripheral part by a hard adhesive agent so that relative positions can not be deviated, and executing adhesion in an outer peripheral part by a spacer equipped with adhesive property so that the relative deviation can be allowed. CONSTITUTION:For A disk A for A side and a disk B for B side, inner periperal parts 1 not to record signals are adhered by a hard adhesive agent 10. The outer peripheral parts are adhered by a spacer 11 eauipped with the adhesive property such as a double coated adhesive tape, etc. Since the spacer 11 adheres the two surfaces to be adhered by adhesive force, the slight deviation is allowed for the two contact surfaces by the viscosity. When the difference of mold shrinkage, difference of thermal expansion coefficient or the difference of a motor to drive the disk is generated between the disks A and B, the distortion such as warpage can be prevented from being generated in the disk since the spacer 11 of outer peripheral parts 2 allows the deviation.
