Patent JP-H01102889-A (JP)
Title: Electromagnetic cooker
Inventor: NODA HITOSHI
IPC: H05B6/12
Filed: 1987-10-14
Abstract: PURPOSE:To reduce power consumption by employing a 2nd coil constituted with a superconductive substance for keeping a magnetic field, making the current applied to a 1st coil in a pulse shape with the polarity thereof alternately changing, and opening the circuit of the 2nd coil once just before said current is applied to the 1st coil to eliminate the magnetic field held. CONSTITUTION:When a current is applied at the time t1 from a power source section 3, a magnetic field (a) is produced with a 1st coil 1, inducing a magnetic field in a 2nd coil 2. Even if the current application to the 1st coil 1 is stopped at the time t2, the magnetic field (a) is held with the 2nd coil 2. Making the current applied to the 1st coil 1 in a pulse shape with the polarity thereof changing alternately, a switch 4 is once opened by a control signal (c) at the time t3 just before applying a current to the 1st coil 1 to open the circuit of the coil 2 and to eliminate the magnetic field held. This makes the magnetic field (a) alternate, causes an eddy current (b) in a metallic pan 6 to heat the metallic pan 6, and makes it possible to reduce power consumption.

Title: Method of measuring slip rate
Inventor: SHIMIZU OSAMU
IPC: B60T8/1763
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To measure the slip ratio of a tire by detecting a road marker and precisely determining the ground speed of a vehicle. SOLUTION: Magnetic nails are arranged on a road with a period of a prescribed pitch so that N-pole and S-pole are alternately arranged. A wheel speed sensor 11 detects the rotation of a wheel and transmits it to a waveform shaping part 1a. A wheel speed calculating part 11b determines the wheel rotating speed from the change of pulse signal of the shaping part 11a and then calculates the wheel speed. On the other hand, a magnetic field detecting part 13 provided on the bottom part of a bumper senses the magnetic nails on the road and transmits it to a ground speed calculating part 16 through the waveform shaping part 13a. The calculating part 16 calculates the ground speed from the time change frequency of the code of the output voltage. A slip rate calculating part 18 calculates the slip rate of the tire from these ground speed and wheel speed.  Thus, a proper alarm can be given to a driver, and an effective brake operation can be performed in automatic operation.

Title: Fluid pressure cylinder for completely eliminating fluid leakage
Inventor: KAWAHARA SAKAE
IPC: F16B21/00
Filed: 1992-09-01
Abstract: PURPOSE:To prevent fluid from leaking while a material is supported by making pressure fluid for pressing and moving the material in the fixed direction in relation to a piston to stay in a cylinder until the material support at the fixed position is completed after being pressed and moved or only for a short time when the supporting position is changed. CONSTITUTION:When pressure oil is forced to flow into a hydraulic cylinder 1, a piston 13 is moved rightward by pressing a left side surface 13a, and when a piston rod 17 is moved by a fixed stroke, a material is moved to the fixed position and supported by a protrusion 25. When a pressing/lifting body 61 is turned, a force transmitting member 51 is moved to the center, and a spring member 63 is shortened, moreover the spring force acts on a moving clutch member 43. The piston rod 17 is stopped in the fixed stroke position by the mesh of the moving clutch with a rack member 71 and maintains the material to support even if the pressure to the left side surface 13a is released. Since the pressure oil stays in the hydraulic cylinder 1 for a short time until the piston rod 17 is moved to the fixed direction, it can be prevented from leaking from the hydraulic cylinder 1.

Abstract: PURPOSE:To improve the detection precision without reducing the flaw detection efficiency in particular by synchronously performing the alternate inversion of the magnetic field direction and the alternate inversion of the analysis direction at the cycle shorter than the output cycle of the image signal of an image camera. CONSTITUTION:A V/F converter 22 and a frequency divider 37 serving as an inversion control means synchronously perform the alternate inversion of the analysis direction via a magnet driver 38 serving as an excitation inverting means and the alternate inversion of the analysis direction via a coil driver 39 connected to an electric coil 8b serving as a rotation energizing means at the cycle shorter than the image output cycle of an image camera 9. When a flaw 10 exists on the surface of a flaw subject material, a flaw image of black and white stripes corresponding to the flaw 10 appears on a magneto- optical effect element. The ratio of areas of white stripes and black stripes of a flaw image is inverted by the inversion of the magnetic field direction, however no inversion occurs in the magnetic domain pattern region. When the analysis direction is inverted, both black and white stripes of the flaw image and magnetic domain pattern are inverted.

Abstract: PURPOSE:To remarkably reduce the number of assembly adjusting man-hours by detecting the prescribed position of a focusing lens capable of moving along an optical axis with a position sensor, storing the difference between the prescribed position and reference position of the lens, and driving the lens based on stored contents with a lens driving means. CONSTITUTION:By the instruction of a control means 30 a stepping motor 23 is driven and a focus cam 18 serving as a converting member is driven via a motor driving circuit 32, and the focus lens L1 is moved. A position which is shifted by the prescribed number of steps from the position is defined as an initial position. Then, a value for a lens reference position A stored in a storage means 33 is read out to allow the initial position to correspond with the number of steps A. The value A is written in the storage means 33 in such a manner that the number of steps between a first position and a second position is measured, when a camera is assembled and adjusted. Therefore, when the number of steps is 0, the position of the lens L1 corresponds to the reference position; that is, an infinite position, and focusing is carried out based on range finding data 31 by using the position of the lens L1 as the reference position.
