Patent JP-H10155289-A (JP)
Title: Vibration equipment and vibration controller
Inventor: HAYASHI TEI
IPC: H02N2/00
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To obtain stable high speed vibration, by making the polarity of a cyclic voltage applied to both phase of electric-mechanical energy conversion elements reverse to each other. SOLUTION: A transformer 4 has a primary winding and a secondary winding which are wound in the same direction, but a transformer 13 has a primary winding and a secondary winding wound in reverse direction. Also, the primary windings of both the transformers 4 and 13 are wound in the same direction each other. In this way, the polarity of the secondary side of both the transformers 5 and 14 is reverse to each other, so that a voltage appearing at the ungrounded terminals of the piezoelectric elements 5 and 14 of the oscillatory wave actuator has a distortion in the waveform.  When the voltage is applied to the piezoelectric elements of A-phase electrode and B-phase electrode as stated above, even though there is a coupling due to mechanical and electric leakage between A-phase and B-phase, the positive and negative amplitude difference of the synthesized wave of its sum is canceled, and thus the occurrence of abnormal sound during high speed rotation and an increase in rotational irregularity can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To obtain a skill of a stop operation for all players at a certain speed level according to player's preference for enjoying hitting aims by constituting the machine possible to alternate a speed of constant speed movement of the pictures by a speed alternation operation conducted by the player. SOLUTION: A microcomputer 54 has a function for alternating a speed of a reel rotation in such a way that waiting numbers for interruption are reduced according to operating signals from a rotation speed increasing switch 44a and are increased according to operating signals from a rotation speed decreasing switch 44b. For example, when the rotation speed increasing switch 44a is operated, a subsequent reel rotation speed set to a set speed of normal game condition without a speed alternation operation at a level not so much easy to hit desired aims for a skilled player. When the rotation speed decreasing switch 44b is operated, a subsequent reel rotation speed is set to a fixed set speed lower than the set speed of the normal game condition at a level not so much difficult for a player having inferior eyesight in motion and a beginner.

Title: Radio calling connection system
Inventor: YATANI TADASHI
IPC: H04W84/02
Filed: 1988-12-12
Abstract: PURPOSE:To improve the convenience for users not only by displaying the telephone number of a calling subscriber on a pager, but also by connecting a called subscriber automatically to a calling subscriber being held only by inputting the telephone number of the called subscriber and a called display signal to an exchange in a system which calls the page automatically in telephone absence. CONSTITUTION:When there is incoming call to a telephone set 1 whose absence is registered in the exchange 3, an audio response guiding device 7 informs the caller that the telephone set is in an absent state and also calls the pager 2 by radio. The person who carries the called pager 2 dials the telephone number of the absence-registered telephone set 1 from a proper terminal 9 and then the exchange 3 connects the terminal 9 to the originating telephone set 4 automatically. Therefore, the caller is connected to the absent called subscriber while the telephone circuit is held. Consequently, troublesome operation is not necessary.

Title: Optical fiber cable and method for measuring length thereof
Inventor: MIYAMOTO SUEHIRO
IPC: G01B11/02
Filed: 1990-11-16
Abstract: PURPOSE:To accurately find out the length of a cable by inserting a pipe in the center of a central tension member and inserting an optical fiber in the pipe. CONSTITUTION:Since the central tension member 10 is in the center of the cable and the pipe 12 exists in the member 10, the center axis of the pipe 12 is aligned with the center axis of the cable. Then, the pipe 12 is not twisted, so that it is straight. When the cable is like a straight line, the pipe 12 is also like a straight line and when the cable is curved, the pipe 12 is also curved at the same curvature. Since the optical fiber 20 is in the pipe 12, the length of the optical fiber 20 is equal to the length of the cable. Even when the cable is curved, the length does not change. Therefore, the length of the cable is accurately known by measuring the length of the optical fiber 20.
