Title: Tracking control system envelope detection circuit for video device
Inventor: SUGIMOTO KAZUHIKO
IPC: G11B5/588
Filed: 1990-06-11
Abstract: PURPOSE:To enable exact tracking control with satisfactory responsiveness while preventing the influence of noise by clamping the output of an envelope detection circuit to a prescribed reference potential lower than a detection output corresponding to the timing of generating head switching noise. CONSTITUTION:The outputs of envelope detection circuits 13 and 23 are clamped to the prescribed reference potential lower than the detection outputs corresponding to the timing of generating the head switching noise while driving a switch circuit 2 according to a head switching pulse 7 of a head switching pulse generating circuit 4 and a timing circuit 3. Therefore, during a period when the head switching noise is generated, a capacitor to hold the envelope detection outputs is not affected by charging caused by the noise. As the result, since a voltage is not shifted to a high voltage side by the head switching noise, error is hardly generated in the calculation of a controller side to calculate the tracking control corresponding to the envelope detection outputs. Thus, exact tracking control can be realized with satisfactory responsiveness.

Title: Membrane structure of low temperature tank
Inventor: YOSHIHARA TAKEO
IPC: F17C3/06
Filed: 1978-12-12
Abstract: PURPOSE:To allot proof against thermal distrotion and pressure distrotion to each membrane, by attaching a pressure distortion proof membrane to corrugation of a heat insulating material and a thermal distortion proof membrane to a flat pressure distortion proof membrane, respectively. CONSTITUTION:The inner pressure in a tank under working conditions fluctuates in accordance with the amount of liquid or gas stored there, and the pressure on each membrane 12 also changes according to the conditions. Since the membrane is attached to a heat insulating member 1 at the flat portion 13, the pressure change is not immediately transferred to the heat insulating member 1 to cause distortion. The pressure distortion tends to grow at a corrugated portion 2, but the external corrugation 12 is not directly distorted because the pressure is transferred from an anchor 3 to the heat insulating member 1 through the internal corrugation 4. As for the thermal distortion, the distortion on the thickness of membrane is determined very small compared with the level of permissible distortion.
