Title: Clock switch control system
Inventor: TAKANO RYOJI
IPC: G06F1/04
Filed: 1988-10-31
Abstract: PURPOSE:To prevent the pulse break which is caused at production of an internal clock signal by switching an external clock signal with use of a clock selection signal which is produced in a period of a clock disable signal and at the same time masking the internal clock signal for the period of the clock disable signal. CONSTITUTION:A selection circuit 2 consisting of a shift register produces a switch signal with delay of a prescribed time at input of a clock selection signal and also produces a clock disable signal. An external clock signal selected by a switch 1 is inputted to a pulse break preventing circuit 3. The circuit 3 masks the output clock signal of the circuit 1 and outputs it in response to the signal that is obtained by securing the synchronization between the clock disable signal and the output clock signal of the circuit 1. Thus the pulse break, if produced at switching of the clock of the circuit 1, is masked and never affects the output internal clock signal.

Title: Optical information recording disk reproducing device
Inventor: KARITA YOSHIHIRO
IPC: G11B7/09
Filed: 1987-10-30
Abstract: PURPOSE:To maintain the perpendicularity of the optical axis of an objective lens regardless of the state of a disk and to laminate the need of mechanical adjustment by using an information reading laser beam itself as a light source for detecting the perpendicularity. CONSTITUTION:A laser beam emitted from the objective lens 6 is reflected on the disk 20, and a part of diffraction reflected light is made incident on photodetectors 7 and 8 provided on the outside of the objective lens. At this time, unbalance is generated in the detected output of the photodetectors 7 and 8 if the optical axis is not set perpendicularly. A motor is operated by a differential signal, and the tilt of a pickup 1 is adjusted. Thus, since the perpendicularity is detected by the information reading laser beam itself, a normal operation can be obtained and no mechanical adjustment is required even in the disk with partially different reflectance without depending on the state of the disk.
