Title: Magnetic storage device
Inventor: ENDOU KENICHI
IPC: G11B21/21
Filed: 1981-12-28
Abstract: PURPOSE:To obtain optional floating clearance at an optional track position, by controlling the floating clearance on the basis of floating clearance signal from a floating clearance detecting element. CONSTITUTION:In a figure, 7 is a host disk controller, 8 is a spindle motor, and 1 is a disk medium; and 3 is a floating head, 5 is a floating extent detecting element, and 9 is a control part for the pressure of the floating head to the disk medium. Further, 10 is an actuator. Then, the control over the pressure of the floating head to the disk medium is performed by the floating clearance signal from the detecting element 5 and a track position signal from the host disk controller. By this control method, the floating clearance is specified as shown by, for example, a floating clearance characteristic curve 12 to obtain a reproduction output signal characteristic 13.

Title: Terminal relay
Inventor: TSUKIHANA MASASHI
IPC: H03K17/00
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To prevent the output current of an output element such as a transistor and the tolerable ambient temperature of a terminal relay from being suppressed owing to the heat generation of an input resistor of a contactless relay due to an input current irrelevantly to an input voltage by connecting the input resistor of the contactless relay to a mount part of a printed wiring board where the contactless relay is mounted. SOLUTION: The resistor 2 is mounted on the reverse surface of the printed wiring board 1 where the contactless relay 5 is mounted and isolated from the contactless switch 5. This resistor 2 as a heat generating body is arranged separately from the contactless relay 5, a transistor in a contactless contact relay case is neither affected thermally nor suppressed in a tolerable ambient temperature as a terminal relay. When an input rated voltage is DC5V, this is usable similarly to a contactless relay 5 of DC5V. Further, a conductor of 0Ω in resistance value is connected instead of the resistor so as to share the printed wiring board 1. Therefore, the printed wiring board 1 can be shared and a further inexpensive terminal relay can be obtained.

Title: System and method for operation of apparatus as well as recording medium with its recorded control program
Inventor: OSADA SEIYA
IPC: G11B31/00
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus operating system in which it is not required to decide information on the connection between apparatuses in advance and in which a new apparatus can be added and replaced easily. SOLUTION: When an instruction of 'Reproduce a video tape recorder' is input to an input device 1, an operating-instruction retrieval part 21 retrieves, from a function-information storage part 31, information contents of 'an image and a sound' corresponding to the instruction. In addition, since the attribute of the information contents is 'an output source', an operating-procedure derivation part 22 retrieves, from the function-information storage part 31, information indicating that the information contents are identical and that the attribute is 'an output destination'. As a retrieved result, 'Display' 'a television' and 'Turn on a loudspeaker' are obtained. On the basis of the information, a connecting-operation derivation part 23 obtains the input terminal of the television and the output terminal of the video tape recorder.  A command execution part 24 connects the input terminal and the output terminal, and a video image is reproduced on the television.

IPC: B60T8/58
Filed: 1985-09-27
Abstract: PURPOSE:To construct an antilock controller, so as to prevent so-called spike braking effect when wheel locking tendency appeared, such that it may repress sharp increase of a brake oil pressure occurring accompanied by sudden stroke on a brake pedal. CONSTITUTION:There are provided with a speed detecting circuit 16, which outputs the signal of a wheel rotation speed Vw from the output of a speed sensor 7 which detects the rotation speed of wheels, and a pedal stroking speed detector 19, which detects a time required for a certain stroke range from the output of a pedal stroke sensor 8. Those signals detected by them 16, 19 are input to logic circuit 17. An antilock control is performed to decrease increase or keep a break oil pressure according to the wheel rotation speed VW. Upon a first sharp increase of the brake oil pressure, if a pedal stroking speed exceeds a preset value, a hold valve 10, interposed on the way of a brake oil pressure passage, is closed to prevent the increase over a certain level in the brake oil pressure.
