Title: Synchronizing separator circuit
Inventor: YADA TOSHIAKI
IPC: H04N5/16
Filed: 1990-02-14
Abstract: PURPOSE:To attain stable synchronizing separation by decreasing a reference voltage level of a SYNC tip clamp circuit so as to decrease a clamp level when a synchronizing signal crosses a threshold level of a 1st comparator and the synchronizing signal does not cross a threshold level of a 2nd comparator. CONSTITUTION:The circuit is provided with a SYNC tip clamp circuit 1, comparators 2, 3 and an AND circuit 4, and a video signal is inputted to a terminal (a) of the SYNC tip clamp circuit 1. When the brightness of the inputted video signal is suddenly decreased and the amplitude is reduced, presume that the level of the clamped SYNC tip is boosted and the SYNC tip comes between a threshold level of the comparator 2 and a threshold level of the comparator 3, then the two comparators output a high level simultaneously and the AND circuit 4 outputs a high level. Thus, the level of a variable voltage source V1 is decreased to decrease the clamp level of the SYNC tip. Thus, the circuit is always acted so that the SYNC tip of the video signal is not boosted and synchronizing separation is surely implemented.

Title: Faucet
Inventor: ONDA YUKICHIKA
IPC: E03C1/042
Filed: 1995-02-23
Abstract: PURPOSE: To provide a lightweight structure by forming a body for discharging liquid, a valve element for adjusting a liquid delivery volume and a handle for rotating the valve element, respectively out of synthetic resin. CONSTITUTION: A body 11, a valve element 17 and a handle 40 are formed out of synthetic resin for substantially reducing weight and ensuring easy assembly and transport. The synthetic resin has thermal conductivity substantially lower than metal, and the body 11 is protected against a high temperature rise. Also, a human body experiences a less stimulus, even when coming in contact with the body 11 or the handle 40. When each member is manufactured at an injection molding process, a screw hole or the like can be formed concurrently. At the same time, a machining or plating process can be eliminated. Furthermore, the body 11 and the valve element 17, when made of the same quality of synthetic resin, evenly expand to improve a sealing function. Also, when the handle 40 is turned, only a spindle 18 moves up and down.  Thus, the height of the handle 40 does not change, and the use thereof at a restricted place is allowed. According to this construction, a lightweight structure can be provided and cost can be reduced.

Filed: 1985-02-25
Abstract: PURPOSE:To solve problems of PCM sound due originating from magnetic tape interchangeability, etc., by basing only the error signal of a part close to a PCM area during the reproduction of a PCM audio signal.

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To reduce a worker's exposure by collectively carrying in a plurality of radiation shields provided with a bag for containing a liquid in a shield position and obtaining a shield state. SOLUTION: In a position where radiation is weak, which is remote from a cylindrical container, a beam 1 is lifted by a ceiling crane and water as a shield liquid is filled in a bag of a radiation shield 3. Subsequently, the beam 1 and each shield 3 are collectively transported to the cylindrical container side by the ceiling crane, and lowered in such a manner as to surround the outer periphery of the cylindrical container with the shield 3 by the ceiling crane. If it reaches the shield height, lowering of the crane is stopped to keep the position. In keeping that position, the beam 1 is transferred from the ceiling crane to a bearing post previously installed on the floor to support the beam 1 on the bearing post, whereby the ceiling crane can be used for another work.  Thus, the cylindrical container is surrounded so that radiation emitted from the cylindrical container is shielded by the shield 3 and radiation from the area surrounded with a plurality of shields 3 to the outer periphery is shielded.
