Title: Focus actuator driving device
Inventor: IWASAKI SHOJI
IPC: G11B7/085
Filed: 1988-11-25
Abstract: PURPOSE:To enable the title device to surely make lock-in operations irrespective of a disturbance, etc., by charging the driving voltage of an actuator in a capacitor and driving the actuator with the voltage charged in the capacitor when a switch is changed over. CONSTITUTION:This focus actuator driving device is provided with a driving circuit 41 which drives an actuator 51 by supplying a driving signal to the actuator 51, a driving signal generation circuit 35 which generates periodically changing driving signals, switch 36 which selectively outputs the driving signals and focus error signals to the driving circuit 41, and capacitor 43 which holds the driving voltage of the actuator 51 when the switch 36 is switched and connected in such a manner that the voltage held by the capacitor 43 can be supplied to the driving circuit 41 when the switch 36 is changed over. Then, when the switch 36 is changed over and the focusing error signal is supplied to the driving circuit 41 instead of the driving signals, the voltage held by the capacitor is supplied to the driving circuit 41. Therefore, the power supply to the driving circuit 41 is not interrupted and lock-in operations can be performed surely even when the switch 36 is changed over.

IPC: H04N1/00
Filed: 1987-11-26
Abstract: PURPOSE:To previously prevent the lack of a picture due to restriction on the reception length of a receiver by providing a capacity notice showing that it is the receiver which can convert transmitting source information into the picture, and the notice of transmitting source information on a communication protocol. CONSTITUTION:When a transmitting action starts, a system is in the reception queue of reception capacity notice from the receiver.

Title: Correction of linear polarization of gas laser
Inventor: RI YOUTETSU
IPC: H01S3/034
Filed: 1986-12-17
Abstract: PURPOSE:To obtain a refractive index satisfying the Brewster condition by imparting deformation to a predetermined part of a laser tube by means of a pressing tool or the like. CONSTITUTION:A pressure is applied to a part close to a Brewster window of a gas laser tube 2 by the use of a pressing tool of a ring 5 and a screw 6, whereby deformation is imparted thereto. Due to this deformation, the refractive index of a window 1 changes and becomes a refractive index satisfying the Brewster condition, which minimizes the energy loss within a resonator, whereby the output of a laser light or the internal energy is used effectively. Incidentally, a similar result is obtained also in the cast that the deformation is provided using an adhesive in place of the pressing tool.
