Title: Pressure sensor
Inventor: SASAKI KEIJI
IPC: G01L9/04
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To prevent fluctuation in the caulking pressure from having adverse effect at the time of assembling a pressure sensor by providing a part for supporting the bottom part of an annular fixing member at the time of caulking on the inner side face of the housing. SOLUTION: Step parts for supporting a fixing member are provided on the inner surface of a housing 20 at positions determined by a pressure sensor module 15, a seal member 50, the compressibility of the seal member 50, the shape of the bottom face of a fixing member 40, etc., and the bottom face of the fixing member 40 is brought into contact with the step parts and supported thereat. Consequently, a constant caulking pressure can be transmitted to the pressure sensor module 15 and the seal member 50 regardless of fluctuation thereof and adverse effect on a pressure sensing element can be suppressed. Since direct impact or load is absorbed by the board 11 and the seal member 50 of the module at the time of caulking, adverse effect on the pressure sensor module 15 can be avoided.

Filed: 1989-06-07
Abstract: PURPOSE:To reduce the disturbance of an additional signal to a main signal at the edge of the main signal by devising the device such that the level of additional signal is suppressed at the edge of the main signal where a level of detection output of energy is increased. CONSTITUTION:The correlation between a main signal Y1 and an additional signal Y2 is utilized, the energy by N picture elements of the main signal Y1 is obtained at a transmitter side and a control signal X obtained based thereon is used as a divisor to divide the additional signal Y2 and a quotient output Y2' is subject to frequency multiplex onto the main signal Y1 and the result is sent. The energy of N picture elements of the main signal Y1 is obtained at the receiver side and a control signal X obtained thereon and the quotient output Y2' are multiplied to reproduce the original additional signal Y2. Since the correlation between the control signal X and the additional signal Y2 is warranted, the level of the additional signal Y2 at the edge of the main signal Y1 when the level of the control signal X is increased is suppressed. Then the disturbance of the additional signal Y2 with respect to the main signal Y1 at the edge of the main signal Y1 is reduced.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To quickly test existence of an erasion faulty cell by applying this method to a simple memory tester having no complex processing function such as a mask function and the like. SOLUTION: Storage performance of each cell is tested, data of all cells of a flash memory is written for a flash memory in which the number of storage faulty cells (n) is found, and the number of storage faulty cells (n) is set to a memory tester register. Erasion of data of all cells is repeated by N times, each data is read out in the order of address for each erasion, whenever read out data is faulty, 1 is subtracted from the number of set of a register. As a result of erasion of N times and subtraction of 1, it is discriminated that when the residual number n' of the register is 0, an erasion faulty cell does not exist in the flash memory, and when the residual number n' is smaller than 0, erasion faulty cells of (n'-n) pieces exist.

Title: Polarized electromagnet
Inventor: MATSUSHITA HIDETOSHI
IPC: H01H50/42
Filed: 1981-09-14
Abstract: PURPOSE:To eliminate the loss of magnetic flux by making the magnetic flux of a coil reach magnetic gaps without passing through a permanent magnet. CONSTITUTION:When magnetic flux shown by the broken line is generated within a yoke 1 by exciting a coil 4, the magnetic flux polarization arises in magnetic gaps 10 at both sides of an armature 12 because a permanent magnet 7 produces its magnetic flux in the direction shown by the solid line. This polarization causes the free end part of the armature 12 to rotate in the direction indicated by the arrow and more a movable frame 13 engaging the armature in the same direction, thereby making contact between a fixed contact 22 and a movable contact 20 while breaking contact between a fixed contact 21 and a movable contact 19. At this time the magnetic flux by the coil 4 does not pass through the inside of the parmanent magnet 7, therefore, all the magnetic flux acts upon the magnetic gaps 10, reducing the loss of the magnetic flux and improving the electromagnet's sensitivity and responsiveness.

Abstract: PROBLEM TO BE SOLVED: To remove the labor of adjusting a speed control system by coupling a motor and a machine system actually on the site. SOLUTION: This device is equipped with a P adjuster 4 which operates to zero the deviation between a speed command value and a speed detected value, a torque estimator P which estimates the torque, based on the torque command value and the speed detected value, and an adder 5 which gets the torque command value by adding the output of the P adjuster 4 and the torque estimated value.

The apparent inertial moment J of the motor and machine system 2 is made to conform to the time constant Jr of the torque estimator 6 in a wide frequency range, by enlarging the parameters of the controller 8 based on the time constant of the torque estimator, the gain, and the sampling time.
