Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To enhance durability, stabilize a switching characteristic, and simplify structure by fixedly arranging a moving member of a magnetic body in the vicinity of a track moving by outside operation, and emitting a switching signal by the output of a magnetic sensor for detecting a magnetic field variation corresponding to the movement. SOLUTION: A moving member is a moving magnet 13, and a magnetic sensor is preferable to be Hall elements 2L, 2R annexed to fixed magnetic bodies 7L, 7R of a metal plate arranged at both ends of a track 10A. When a key top 5 in the top of a body case 12 is located on the right side, the moving magnet 13 connecting the key top 5 to a plunger 14 is attracted to the fixed magnetic body 7R at the right end of the track 10A of an under cover 10. When the key top 5 is energized to the left side, the moving magnet 13 moves on the track 10A and is attracted to the fixed magnetic body 7L by magnetic force, the Hall element 2L through which magnetic field is passed outputs a switch signal.  At that time, the moderate feeling and click sound of the switch are obtained, the detection of magnetic force is stabilized with the moving magnet 13, and a non-contact switch having simple structure is obtained.

IPC: G11B15/18
Filed: 1985-07-26
Abstract: PURPOSE:To equalize probability of detection of index signals by oscillating a rotary head in the direction that intersects the direction of scanning relatively to a tape at the time of high speed reproduction. CONSTITUTION:When a switch circuit 84 is turned on by a mode signal MD at the time of high speed reproduction, a random signal from a random signal generator 85 is supplied to an adder circuit 80, and superposed on motor driving voltage. The random signal becomes disturbance of motor rotation, and constant speed of the tape 2 is disturbed by the disturbance. Consequently, locus of rotary heads HA, HB on the tape becomes not linear, and oscillated by the disturbance in the direction that intersects the direction of scanning. The index signal of at least one area of plural tracks in a fixed time can be detected at above a fixed level by the oscillation. Thus, probability of detection of the index signal can be made uniform.

Title: Control device of power assisted steering gears
Inventor: KAWABATA MINORU
IPC: B62D6/02
Filed: 1979-12-20
Abstract: PURPOSE: To prevent a working oil from efflux by a method wherein a valve device, which closes a suction passage when a control pressure of a control pump lowers, is installed at a suction passage of the control pump and a communication between a power assisted steering side and the control pump is disconnected in case of an emergency such as a piping damage.  
     CONSTITUTION: A switching valve 62 is inserted in a suction tube 57 of a pump 50 controlling the operation of a bypass valve and a spool 63 is installed at the switching valve 62. This spool 63 is pressed by a spring 64 to a direction to close a suction passage, however, during a control pump 50 operating, this spool 63 is moved to the direction to open the suction tube 57 because the exhausting pressure of the control pump 50 operates onto the back of the spool from a hole 65. Accordingly, even if an oil leak occurs because of the damage of a tube leading to the pump 50, since the aforementioned valve 62 closes by means of an operation of the spring 64, a working oil of the power assisted steering system is not discharged, thus, enabling to perform the power assisted steering as before.

Title: Pressure calibrator
Inventor: TANIGAWA YOSHIKI
IPC: G01L7/00
Filed: 1986-07-17
Abstract: PURPOSE:To enable calibration of a pressure to be performed at a high accuracy, by setting a desired pressure with a pressure of a reference pressure chamber as absolute pressure under a temperature control to relatively compare the pressure being calibrated with a reference pressure. CONSTITUTION:With a solenoid valve 5 along opened, a vacuum pump is operated to set a sufficiently large vacuum pressure inside a reference pressure chamber 4. When a solenoid valve 7 alone is opened after the closing of the valve 5, iodine of an iodine injection box 8 is evaporated into a pressure chamber 4 to be saturated. Under such a condition, with the closing of the valve 7, the saturated vapor pressure of iodine is maintained inside the pressure chamber 4 to obtain a reference pressure varying with change in the temperature. Then, a detection cylinder 12 of a transducer 10 to be calibrated is connected to an opening 4b and when a solenoid valve 6 is opened to supply this reference pressure to the transducer 10, it 10 detects a differential pressure between a reference pressure chamber B and a measuring pressure chamber A to which this reference pressure is supplied to be outputted as measured value. The detection value is adjusted to a specified value to perform a calibration.

Title: Chuck
Inventor: IKUTA HIROYUKI
IPC: B23B31/175
Filed: 1984-08-08
Abstract: PURPOSE:To ensure the holding of a workpiece by a chuck for a machine tool, by opening and closing a chucking claw through the radial movement of a slider movingly connected to a member which is moved back and forth in the axial direction of the chuck. CONSTITUTION:A leftward force is applied from a driver 17 to a reciprocating member 30 so that a radially inward force is applied to a slider 35 by the power of engagement of a guide portion 35a in a guide groove 30a. A radially inward force is applied to a second slider 45 through a lever 40. A counterclockwise turning force is applied to a chucking claw 50 by the engagement of an engaged portion 50b in an engaging hole 45b to clamp a workpiece W by a chucking portion 50a. When the reciprocating member 30 is moved rightward by the driver 17, the chucking claw 50 is o?pened to unclamp the workpiece W. This constitution prevents the workpiece W from being displaced in the axial direction thereof by the reaction to the clamping. The workpiece is thus surely clamped.

IPC: H04B1/10
Filed: 1990-06-25
Abstract: PURPOSE:To obtain a clear video image by changing the operating mode of a ghost cancel means in response to the drive state of a vehicle. CONSTITUTION:The drive state of a vehicle is detected by a car velocity sensor 34 and a steering angle sensor 36. A ghost canceller 32 obtains a mean value kA of disturbing wave intensity ratios and a mean value  dA of time differences for a prescribed time interval (t) respectively to calculate a ghost cancel signal GCR. Since a change in a propagation path difference and in a disturbing wave intensity between a reference signal and a ghost signal is large when the car velocity sensor 34 discriminates the velocity of the vehicle to be a prescribed velocity or over, a shorter time t1 is selected for the time interval and a relevant ghost cancel signal GCR1 is calculated. When the velocity is less than the prescribed velocity, a ghost cancel signal GCR2 is calculated and an original signal is restored by using the signal GCR1 or GCR2 to obtain a stable and clear image.
