IPC: H01L43/08
Filed: 1992-02-10
Abstract: PURPOSE:To provide a highly susceptible magnetoresistance effect device, in which the magnetic direction of a soft film is easily changeable in an external magnetic field, by arranging the easy magnetization axis of the soft film to be crossed with the magnetizing direction of a hard film. CONSTITUTION:A magnetoresistance effect device is made up of magnetically soft films made of metal, such as Ni-Fe alloy, and magnetically hard films made of metal, such as Co, piled in a given number of layers. In the magnetoresistance effect device, an easy magnetization axis of the soft film is crossed at an angle ranging from 0 to + or -90 degrees with a magnetizing direction of the hard film. The diagram shows data of the easy magnetization axis direction of the soft film (Ni-Fe alloy film) and the magnetizing direction of the hard film, each measured immediately after film formation, in an intense magnetic field, and out of the magnetic field. In the final step, the easy magnetization axis of the soft film (Ni-Fe alloy film) and the magnetizing direction of the hard film (Co film) cross each other in the magnetoresistance effect device.

Title: Method for testing weld zone airtightness
Inventor: NAKAJIMA MASARU
IPC: B23K33/00
Filed: 1987-02-04
Abstract: PURPOSE:To reduce the cost of a product by forming an air duct on one hand of a base metal or a joining member to be butted in advance and carrying out an airtightness test of a welded zone via the air duct after welding. CONSTITUTION:The air duct 4 is worked in advance on a surface contact place between the base metal 1 and the joining member 2 which is to be the weld zone. Holes 5 and 5' for air pressure are bored at points A and B on the welded zone where the welding of the base metal 1 to the joining member 2 is finished and the air pressure is applied from the point A and the pressure is confirmed at the point B and an air leak of a weld bead part between the points A and B is inspected. Since the air duct 4 is formed in advance, the prescribed test pressure is loaded in a moment between the points A and B and the necessary time for the airtightness test is remarkably reduced. Further, since the necessary expenses for testing equipment is reduced, after all, the cost of the product is reduced.

Title: Manufacture of magnetic bubble element
Inventor: MATSUDERA HISAO
IPC: G11C11/14
Filed: 1983-02-16
Abstract: PURPOSE:To decrease the cost by implanting hydrogen ion to a magnetic garnet single crystal film cooled below room temperature to improve the implantation efficiency of the hydrogen ion and decrease the time of ion implantation. CONSTITUTION:Atoms constituting the magnetic garnet causing defects through transposition by the kinetic energy from the collision with hydrogen ions have a small possibility of recovery due to heat energy because of a low temperature like the temperature of liquified nitrogen by cooling the temperature of the magnetic garnet film during implantation of hydrogen ions to a temperature below room temperature, e.g., the temperature of liquified nitrogen, and the storage of amount of damage to the crystal due to the defects is increased at the same amount of implantation in comparison with the implantation at a room temperature or above. Since the temperature of the magnetic garnet is brought to a temperature below room temperature even if the implantation speed is increased, the recovery of defects hardly takes place. Thus, a prescribed amount of crystal damage is obtaind while increasing the implantation speed with less amount of implantation in comparison with the implantation at room temperature or above.

Abstract: PROBLEM TO BE SOLVED: To carry a sheet like member in a stable state and eliminate generation of vibration and sudden sound, even when carrier speed or carrier load is changed, by providing a load means applying load to a rotation transmission means and changing this load by prescribed timing. SOLUTION: A load device is provided with an elastic member 38 on a supporting member 39, a friction member 37 which is pressed on a flat side surface 26d of a rotary disc body 26b by this elastic body 38 via a plane plate 40 and an actuator 35 operating a bar-shaped abutting member 35a which is abutted on the plane plate 40. When an instruction is given from a control part 36a to a driving part 36 by a detection signal, the actuator 35 projects the abutting member 35a in an (x) direction and abuts the abutting member 35a on the plane plate 40. By displacement of this plane plate 40, the friction member 37 and a plane part 38b of the elastic member 38 move in a direction that the member 37 and the part 38b separate from the flat side surface 26d. Thus, frictional force is reduced and load on a belt mechanism 26 can be reduced.

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide the camera direction controller of a remote operation machine, which can obtain a picture with satisfactory operability without using an operation lever for panhead with only one camera. SOLUTION: A panhead 81 provided with a camera 8 is fitted to the upper revolving body 12 of a hydraulic execrator. The video signal of the camera 8 is transmitted to a monitor 9 at a remote place. An operator at the remote place remotely operates the hydraulic excavator 1 through an operation-side controller 4, a radio machine 6 and a vehicle-side controller 5. The vehicle-side controller 5 operates an angle difference between the direction of the pin 15p if a packet 15, which is viewed from the camera 8, and the view center direction of the camera 8. Dead zones are provided for the angle differences is upper/ lower directions of the pin 15p. When the angle difference exceeds the dead zone, the panhead 81 is driven at prescribed angular speed and the pin 15p is traced.  Thus, the fine movement of the picture at the time of a micro operation is inhibited and operability is improved by providing the dead zone.

Abstract: PURPOSE:To generate satisfactory rotational torque by providing an eccentric means in a rotational displacement converting section, which means varies the converting ratio of converting straight line motion to rotational motion with rotational angle. CONSTITUTION:Ropes 3, 4 are respectively connected to movable ends of artificial rubber muscles 1.2, wound around groove portions of spiral pulleys 5A-1, 5A-2 having large radius of curvature from spiral groove portions having small radius of curvature and then connected to the ends 9, 10 of arms 8. the increase and decrease of rotational torque due to the variation of contractive force are offset by the difference between the respective products of the contractive forces of artificial rubber muscles 1, 2 and those of pulley. Thus, the reduction of contractive force is compensated so that satisfactory rotational torque can be generated.

Filed: 1987-02-06
Abstract: PURPOSE:To effectively control the impression of an anode voltage, to minimize power consumption, and to amplify a signal for an amplifier whose time ratio is limited with maximum activity efficiency, by utilizing the destination signal of an input burst signal. CONSTITUTION:By detecting not only the leading edge but the trailing edge of a destination burst wave signal, a reactive time at the time of falling is eliminated even when a signal burst length is not constant, and furthermore, if the arrival timing of the next burst wave signal exceeds a time from the trailing edge of a preceding burst wave to the sum of the rising time and the falling time of the anode voltage, it is possible to improve the activity efficiency by performing the switching of the impression of the anode voltage once. Also, in the measurement of the impression time ratio of the anode voltage, by counting the rising time and the falling time in addition to a burst signal wavelength, the detection of the time ratio can be performed exactly.
