Title: Key driver for automatic keyboard musical instrument
Inventor: MURAMATSU SHIGERU
IPC: G10F1/02
Filed: 1989-11-28
Abstract: PURPOSE:To improve the accuracy of key touch/detach control and to decrease the noises at the time of key driving by providing a pair of coils perpendicularly to the driving direction of keys, yokes fixed thereto and a movable yoke suspended in the magnetic field generated by the same atop a rack. CONSTITUTION:A magnetic field is generated when a driving current is passed from a controller to the coils 1, 2. Driving force is then generated between the stationary yokes 1A, 2A and the movable yoke 3. There is a window 5 in the movable yoke 3 and the area facing the stationary yokes 1A, 2A is variable. The left side of the yoke 3 receives the pushing down force F1 and the right side receives the pushing up force F2 when the coil 1 is energized. The key 73 (74) fixed to the yokes 1A, 2A is driven by the balance of the F1, F2. The gap change ratio of the yoke 3A with respect to the yokes 1A, 2A is maintained constant by the open window 5 even if the lifting position of the key varies and, therefore, the thrust of the key remains approximately constant unless the energizing current is changed. The control accuracy to the key is improved and the noises at the time of the key driving are decreased.

Abstract: PURPOSE:To improve the accuracy of key touch/detach control and to decrease the noise at the time of key driving by providing a coil in the direction orthogonal with the oscillation direction of a key, a movable yoke opened on the rear surface of the key and a stationary yoke varying in the area facing the movable yoke along the oscillation direction of the key, atop a rack. CONSTITUTION:Attraction force is generated between the stationary yoke 2 and the movable yoke 3 and the key 73 (74) is attracted together with the yoke, etc., downward when a driving current is passed from a controller to the coil 1. The change in the attraction force can flatten the characteristic of the key thrust by a difference in the lifting position of the key 73 (74) when the angle theta of the taper T of upright plates 2b, 2c of the stationary yoke 3 is set at a proper value while the coil current is constant. Since a space S is formed at the center of the body 3b of the yoke 3, a magnetic vector F is generated along the oscillation direction of the key 73 (74) between the yokes 2 and 3. The key is surely actuated in the oscillation direction by effectively utilizing the perpendicular component F1 thereof, by which the operation control accuracy of the key is improved and the noises at the time of the key driving are decreased.

Filed: 1990-11-16
Abstract: PURPOSE:To surely perform fusion connection with low loss by previously deviating the axes of outside diameters, observing an optical fiber image in the middle of discharge after starting fusion and stopping the discharge when both core axes are aligned. CONSTITUTION:Optical fibers 1a and 1b are butted and the cores 11a and 11b are aligned while they are observed by a TV monitor 9, and the outside diameters are moved by a moving amount calculated based on the eccentric amount of the cores 11a and 11b. Then, the discharge is started. Discharge power is made weaker than usual. The axis of the outside diameters are mutually moved by surface tension in a direction where the deviation of the outside diameter is decreased. During this movement, image processing is performed while the optical fiber image in the middle of the discharge is observed by the monitor 9. When the core axes 11a and 11b are aligned and the connection loss becomes minimum, the discharge is stopped to obtain the connection where the core axes are aligned. By using a filter 7a, the alignment of the core axes are confirmed by visual observation.
