Patent JP-H11296108-A (JP)
Title: Display device
Inventor: NATORI TAKEHISA
IPC: G09F9/33
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To improve uniformity on a screen and to provide excellent visibility by deviating the maximum emitted light intensity direction of a light emitting element from a direction perpendicular with a mounting surface. SOLUTION: By attaching a light emitting element inclination regulating component 8 by fitting each LED 6 into a long hole 12 on the light emitting element inclination regulating component 8, the light emitting element inclination regulating component 8 is arranged while deviating the LED 6 downward with respect to a light emitting element attaching substrate 7 in the state of covering each LED 6. Thus, a maximum emitted light intensity direction 9 of each LED 6 is directed downward by an angle θ with respect to a perpendicular L. This perpendicular L is the one to the light emitting element inclination regulating component 8 and the light emitting element attaching substrate 7 and it is preferable for the inclination between the maximum emitting light intensity direction 9 and the perpendicular L to be angle θ of from 2 to 45 deg. in down ward direction.  When this angle θ is smaller than 2 deg., it is not preferable since a difference from conventional 0 deg. is a little and when this angle is larger than 45 deg., it is not preferable since the neck or the like is tired at the time of locking up the display for a long time.

Title: Floating variance measuring method of magnetic head
Inventor: TAKAHASHI MINORU
IPC: G11B5/60
Filed: 1983-05-26
Abstract: PURPOSE:To measure easily the floating vibration characteristics of a magnetic head on the surface of a revolving magnetic disk and to improve the productivity, by irradiating laser beams in division to the back side of the magnetic head as well as to an interference reference reflector and making the reflected light of those beams incident to a photodetector. CONSTITUTION:The laser beam radiated from a laser oscillator 12 is irradiated to the back side of a magnetic head 3 receiving the prescribed vibrations from a vibration generator 10 through a semitransparent mirror 13 and the 1st 1/4lambda deflecting plate 14. Then the reflected measured light is deflected by 90 deg. by the reflector 13 through the plate 14 and made incident to a photodetecting part 17. While a part of the laser beam is deflected by 90 deg. by the reflector 13 and irradiated to an interference reference reflector 16 through the 2nd 1/4lambda deflecting plate 15. Then the reference reflected light is irradiated again to the part 17 through the plate 15 and the reflector 13. In such a constitution, a detection signal processing part 18 detects the floating variance of the head 3 including the revolving deflection of a magnetic disk 1 on the basis of the interference fringes produced by the measured reflected light and the reference reflected light. This ensures the easy measurement of the floating vibration characteristics in a short time and high accuracy.

Title: Negative pressure servo motor
Inventor: ITOU TOMOO
IPC: F15B5/00
Filed: 1982-06-04
Abstract: PURPOSE:To achieve accurate positioning control of a diaphragm regardless of any variation in load weight by providing both a leak passage provided with a valve unit arranged on a diaphragm face of a diaphragm mechanism and an actuator which opens and closes the valve. CONSTITUTION:When a load applied to a servo motor is increased, a diaphragm 10 is moved rightward. A valve unit 23 therefore comes close to a leak passage 17 to reduce the inflow of atmosphere into a negative pressure chamber 12 so that a negative pressure therein is intensified to move the diaphragm 10 leftward again. If the load is reduced, the valve unit 23 goes apart from the passage 17, however, it is returned to the original position. When a signal negative pressure is weekened, a signal diaphragm 18 serving as an actuator is moved leftward to bring the valve unit 23 to the proximity of the leak passage 17, hence intensifying a negative pressure in the negative pressure chamber 12 to move the diaphragm 10 leftward. This is similar when the signal negative pressure is increased. Resultantly, the diaphragm 10 comes to a stop in position, and meanwhile, follows the diaphragm 18 which is operated by signal negative pressure.

Abstract: PURPOSE:To obtain a welding effect whose exfoliation strength is sufficient by a method wherein a part to be bonded is brought into contact with a circuit board part from which an insulating material has been removed and both are bonded by giving ultrasonic vibrations in a state that a static pressure is applied. CONSTITUTION:Two printed-circuit boards 3 are welded ultrasonically, and conductors (copper foils) 5 on the printer-circuit boards 3 are insulated and protected by insulating materials 4 as polyimide films. In the insulating materials 4, faces, on one side, of the circuit boards 3 are removed in advance in parts in which welded parts are faced in such a way that the insulating materials 4 do not adhere to the parts when the circuit boards 3 are formed in advance. A static pressure is applied to the direction of an anvil 2 by using an ultrasonic vibrator 1, and the vibrator 1 is vibrated in parallel with bonding faces, and the conductor 5 and the conductor 5 are melted by the action of frictional heat so as to be metal-bonded. Since the insulating materials on the faces, on one side, of the circuit boards are removed in advance, objects to be bonded are brought into contact with the removed parts, both are pressurized and bonded by applying the ultrasonic vibrations, the conductors come into direct contact with the parts to be bonded, and it is possible to prevent a welding operation from becoming imperfect when the insulating materials constitute an obstacle.
