Title: Carrier suppression circuit
Inventor: SASAKI KANEHITO
IPC: H04B1/04
Filed: 1984-12-28
Abstract: PURPOSE:To suppress a carrier with optional suppression when a voice signal is not detected by a voice signal detector by using a DC voltage applied from a suppressing amount setting circuit so as to change the attenuation (suppressing amount) of a voltage variable type attenuator provided at the post-stage of a modulator. CONSTITUTION:The carrier inputted from a terminal T12 is modulated by a voice signal inputted from a terminal T11 and the result is fed to a voltage variable type attenuator 13. For example, a digital signal outputted from a suppressing amount setting device 14 is converted into a DC voltage by a D/A converter 14a, fed to the voltage variable type attenuator 13 to control the suppressing amount. When the voice signal Vs is detected by a voice signal detector 11, the output voltage controls a suppressing amount setting device 14b so that the attenuation of the voltage variable type attenuator 13 is almost zero, and when the voice signal Vs is not detected by a voice signal detector 11, the carrier is suppressed by a prescribed amount or completely by the voltage variable type attenuator 13 according to the setting value of the suppressing amount setting device 14b.

Title: Shell for optical disk cartridge
Inventor: HAYASHIDA HIDEO
IPC: G11B23/03
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To make unnoticeable scratches or flaws on a resin case generated when a metallic shutter slides even when the resin case is formed of a transparent resin or soft resin, by providing a projection at a surface of the resin case for limiting a place where the metallic shutter slides. SOLUTION: A resin case 1 and a projection 4 are formed by injection molding in one body. The straight projection 4 is formed along a movable direction of a metallic shutter 2 at a face 3 of the metallic case where a lower part of the metallic shutter 2 slides. Therefore, a sliding place of the shutter 2 on the face 3 is limited to on a top of the projection 4. Since the generation of scratches or flaws at the sliding time is concentrated on the top of the projection 4, design features are not considerably damaged. If a projecting part of the projection is formed with a large curvature, the projection becomes hard to distinguish by eyes, which is favorable from the design viewpoint.

CONSTITUTION:A hydraulic assist mechanism comprising a power cylinder device 7, a rotary valve 30, an oil pump 46, and a reservoir tank 47 is mounted on a first steering angle mechanism (steering gear) 2 to steer a steering wheel. An assist force is controlled by means of a controller 100, a reaction force mechanism 20, and a pressure control valve 50 and steering is effected by the first steering mechanism 2.
