Title: High-speed retrieval system for video information content of video disk
Inventor: RIYUUKOU KAZUO
IPC: H04N5/76
Filed: 1979-05-09
Abstract: PURPOSE: To make stable and high-speed retrieval possible for reproduced pictures which never cause disturbance, by performing the high-speed retrieval under tracking servo-control by the use of a track shift pulse signal generated at a random time position.  
     CONSTITUTION: Driving mechanism 15 putting reproducing element 2 into servo- tracking operation is applied with control pulses from track reference signals of both sides of a track through LPF 4 and BPFs 5, 6, 12 etc., control pulses from control pulse generator 13 detecting a rotary-phase signal, etc., and a track displacement signal, etc., from differential amplifier 10. To retrieve a desired image under a supervision over a reproduced picture, retrieval signal generating circuit 16 generates a track shift pulse at a random time position corresponding to retrieval direction signal T and it is applied to mechanism 15 together with the pulse from generator 13. As a result, element 2 is track-moved under tracking servo-control, so that stable and high-speed retrieval which neither disturbs the reproduced picture nor de- teriorates video information and disperses noises in terms of time can be carried out.

Title: Wire-electric discharge machine
Inventor: KOSHIO YASUHIRO
IPC: B23H7/02
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To minimize the thermal displacement of a lower arm, which is caused by changes in ambient temperature, and the relative displacement between an upper wire guide and a lower wire guide. SOLUTION: A cylindrical hollow section 27 is formed in a peripheral wall section comprising the outer periphery of a lower arm 13 in which a lower wire guide 14 is provided, and air is sealed in the hollow section 27. When temperature increases in the machining liquid 9 during electric discharge machining, the temperature of the outer periphery of the lower arm contacting the machining liquid 9 also increases, but because heat transmission is cut off by the layer of the air 28 in the peripheral wall section of the lower arm 13, the temperature of the whole of the lower arm 13 is hard to increase, restricting thermal displacement. For this reason, the relative displacement between an upper wire guide and the lower wire guide is minimized, preventing the lowering of machining accuracy.
