Title: Flow adjusting valve
Inventor: NAKAMU KEIICHIRO
IPC: F16K31/54
Filed: 1991-07-04
Abstract: PURPOSE:To eliminate any leak when a valve is closed by rolling and driving a roller to control openings of two fluid inlets by means of the side part of the roller, and controlling the opening of a flow adjusting hole through a plate- shaped valve having rubber-like flexibility. CONSTITUTION:When a roller 28 is positioned on the right of a casing 20, thereby a fluid inlet 24 is fully closed on the side of a roller 28 and a fluid inlet 23 and an outlet 26 are fully opened, the fluid from the inlet 23 only flows out to the side of the outlet 26. When the roller 28 rotates to the left, thereby the both inlets 23, 24 are fully opened, the fluid from the inlets 23, 24 mix together and the mixture flows out from the outlet 26. When the roller 28 further rolls to the left, thereby the inlet 23 is fully closed on the side of the roller 28, and the inlet 24 and the outlet 26 are fully opened, the fluid from the inlet 24 only flows out from the outlet 26. Also, when the roller 28 rotates to the left, a plate-shaped valve 29 above the roller 28 is unwound to cover a flow adjusting hole 25, and shuts off the outflow of the fluid. Since the plate-shaped valve 29 is in a rubber-like shape, it can perfectly prevent the leak of fluid even if a foreign substance sticks to the flow adjusting hole 25.

Title: Position detector
Inventor: ISHII TAKESHI
IPC: G05D3/10
Filed: 1986-07-15
Abstract: PURPOSE:To eliminate the need for wiring, etc., such as a signal line from an initial position and to eliminate a mechanical contact, etc., by detecting counter electromotive force generated when a body conveyed by being driven by a stepping motor abuts on a stopper to reverse, and detecting the arrival of the driven body at a specific position. CONSTITUTION:The upward raised part 26 of a stop ring 25 is pressed against an initial stopper 29 and inhibited from further rotating as shown by an arrow. Then, the upward raised part t is held in the pressed state at the position of the initial stopper 29 even through the excitation of phases 9-11 because the stopper position is closer. In the excitation state of a phase 12, the motor is caused to reverse at positions (c) and (k) as stable points of B-phase excitation because a position (c) is closer, so that counter electromotive force is generated in a phase A as a nonexcitation phase. This counter electromotive force is detected by a counter electromotive force detecting circuit 5 and recognized by a control part to detect the stepping motor reaching the initial position.

Title: Method for detecting existence of disk in disk player
Inventor: SAKAE JUNICHIRO
IPC: G11B19/10
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in detection of the existence of a disk in a disk existence detecting method for a disk player detecting the existence of a disk by using an FE(focus error) signal. SOLUTION: The FE signal detected from a PU (pickup) 3 is compared with the threshold VTH, and the existence of a disk is detected when the FE signal is larger. By a level detecting part 13, an offset value is calculated from a signal line of the FE signal to change the threshold. By an amplitude detecting part 14, the amplitude of a sigmoid signal of the FE signal is detected to change the threshold by the amplitude value. By this procedure, the adverse effect due to the variance in the offset of the FE signal is eliminated when the levels of the FE signal and the threhsold are compared. Further, the existence of the disk is detected alternatively by another detection method with the higher detection sensitivity succeeding the detection method using the FE signal.
