Filed: 1987-02-26
Abstract: PURPOSE:To obtain an optical information recording medium having high performance and reliability, by providing a recording layer comprising a cationic light-absorptive coloring matter and a high molecular weight crown compound, on a substrate. CONSTITUTION:When a high molecular weight crown compound is incorporated into a recording layer provided by using a cationic light-absorptive coloring matter, the coloring matter is favorably dissolved in an organic solvent which does not attack a plastic substrate, and a homogeneous recording layer can be provided. In addition, an optical information recording medium having excellent environmental stability and high reliability can be obtained. The high molecular weight crown compound may be a homopolymer or copolymer of a monomer comprising a crown ether having O as a donor atom. The cationic light- absorptive coloring matter may be a polymethine coloring matter, a diphenylmethane or triphenylmethane coloring matter or the like. Particularly, when the crown group in the crown compound is used in an amount of 1 or 2 mol per 1 mol of the coloring matter, little lowering in the reflectance of a coated film is observed, and C/N is not lowered.

Filed: 1995-03-01
Abstract: PURPOSE: To improve the durability of a hydraulic actuator through size reduction, etc., of a motor in use and also to properly prevent any slant contact between a cam and a cam follower so as to prevent wear of both components. CONSTITUTION: A rod part 19 which makes following action on the cam surface of an end surface cam part 18 driven by a motor 17a has such a construction that a cam follower 19c is provided on one end and the other end thereof comes in contact with a piston 16a, and the contact point of the cam and the cam follower stays on a line extended in the direction of a piston displacement. A cylinder 15 can be arranged just above the contact surface between the cam and the cam follower, so that downward force from the piston and upward force from the cam may act on the same shaft, thus less falling-down of the rod may be expected. The motor size is reduced by restricting any increase in sliding friction, any slant contact between the cam and the cam follower is prevented so as to prevent their wear for aiming at improvement in their durability.  If a motor is received in a space produced in the central part of the cam, a space equivalent to the size of the motor can be saved and miniaturization of the actuator can be further attempted.

Abstract: PURPOSE:To avoid a sense of displeasure in a video and an audio signal caused at interblock of the signal by cutting off an audio output in the absence of a broadcast signal or a base band signal, cutting off noise as to the video signal also and outputting a monochroic signal on a display device. CONSTITUTION:Since no synchronizing signal is extracted at a collector of a transistor(TR) Q1 of a synchronizing signal separator circuit in the absence of a broadcast signal, no potential is applied to a base of a TR Q2, which is turned off and the collector reaches a high level via a pullup resistor R6. In this case, a switch 51 is closed to apply muting to an audio signal. Moreover, a switch 52 is closed to avoid the invasion of a noise signal to a video signal processing circuit 2 thereby avoiding a white noise from being displayed on a CRT 5. Thus, a sense of displeasure due to unpleasant video image or audio noise is eliminated.
