摘要： A record disc playing apparatus comprises an address signal generating unit for generating address signals corresponding to horizontal rotational angular positions of a tone arm, a device for generating a rotational angular velocity signal corresponding to the rotational angular velocity of the tone arm, a circuit for controlling the rotation of a motor for driving a turntable, a control device supplied with the address signals and having a memory device from which is from which read out information corresponding to the addresses indicated by the address signals, and an attenuation circuit supplied with the rotational angular velocity signal and operating with an attenuation quantity, with respect to the rotational angular velocity signal, which quantity is varied by a signal from the control device. The rotational angular velocity signal corresponds to the quantity of any eccentricity of the record disc. The control device producing as output signals based on the information thus read out. The attenuation circuit supplying an output signal to the control device. The rotation of the motor is so controlled that a rotational irregularity due to any eccentricity of the record disc is corrected for.

摘要： A shaping apparatus utilizing liquid pressure includes a base constructed of a single member and including a lower die and a lower clamp which surrounds the lower die and is integral with the lower die, an upper clamp movable in a vertical direction above the lower clamp, and an upper die or punch movable in the vertical direction above the lower die. The upper die has a lower surface with a configuration to which a workpiece to be formed is pressformed. The lower surface of the upper die and the upper surface of the lower die define a cavity filled with liquid except for a small air pocket when the upper die is lowered. When the upper die is lowered, the upper die contacts and deforms the workpiece. At the same time, the liquid is contained under pressure in the cavity and presses the workpiece against the lower surface of the upper die so that the workpiece is formed precisely to the configuration of the lower surface of the upper die by the contained liquid.
