Title: Color signal processor
Inventor: UTASHIRO MASATOSHI
IPC: H04N9/64
Filed: 1989-12-22
Abstract: PURPOSE:To attain the hue adjustment of a picture with simple circuit configuration not requiring a modulation and demodulation circuit or the like by varying a phase between a color burst signal and a chrominance carrier signal while using the chrominance carrier signal with a color burst signal added thereto. CONSTITUTION:A capacitance C of a variable capacitor 5 is varied with a control voltage (b) from an input terminal 7. In this case, a change in the capacitance C for a color burst signal period and a chrominance carrier signal period of the input signal (a) is made reverse with respect to a reference capacitor. Thus, a color burst signal and a chrominance carrier signal in an output signal v0 are subjected to phase shift differently and a different phase relation takes place in the color burst signal and the chrominance carrier signal in the input signal (a). Thus, the hue of a picture in the output signal v0 is different from the hue of a picture by the input signal (a) to attain hue adjustment.

Title: Floating type disk brake
Inventor: MATSUZAKI YOSHIKI
IPC: F16D65/02
Filed: 1989-12-22
Abstract: PURPOSE:To prevent an outer pad from uneven wear even if a caliper swings in braking by making the rigidity of an outer claw of the caliper at the disk turning-in side larger than that at the disk turning-out side. CONSTITUTION:An outer claw 6 of a caliper 1 has the rigidity of the disk turning-in side claw 6a larger than that of the disk turning-out side claw 6b so that the wall thickness is ta>tb. The outer claw 6 tends to be opened axially of the disk from the root side start point in braking, while the rigidity of the claw at the disk turning-in side is larger than that at the disk turning-out side, so that the opening amount at the turning-in side is smaller than that at the turning-out side and surface pressure at the disk turning-in side is larger than that at the disk turning-out side when the caliper 1 is assumed to generate no swing. Thus, the surface pressure difference generated in an outer pad by the swing is offset by the surface pressure difference due to the opening amount of the claw to prevent the outer pad from uneven wear.
