Title: Driving circuit of oscillatory wave motor
Inventor: KATAOKA KENICHI
IPC: H02N2/00
Filed: 1990-03-09
Abstract: PURPOSE:To facilitate the stable driving of an oscillatory wave motor constantly by a method wherein an oscillation control gain is switched and an impedance is matched in accordance with the oscillation characteristics and the applications of the individual oscillatory wave motors.

Title: Coaxial core and multi-core cable using it
Inventor: SATO KAZUHIRO
IPC: H01B11/18
Filed: 1988-03-14
Abstract: PURPOSE:To eliminate electrostatic noise and remove influence of external noises by wrapping a plastic tape on an insulation member in such a way that the coating metal layer on one side contacts the metal shield of the upper layer. CONSTITUTION:As hold-wrapping of an insulation member 2 forming a multi- core cable using coaxial cores, a metal plastic tape 3, to whose one side a metal layer is coated, is wrapped in such a way that the metal layer contacts the metal shield 4 such as cross wound shield on the upper layer. This eliminates electrostatic noise which might influence the signal voltage in case such a tape 3 is not used, and there is less likelihood of ill influence of external noises due to cross-talk, etc., when the insulation layer is exposed at the time of terminal processing, because direct contact of the metal surface of the metal coated plastic tape with the metal shield keeps the potential zero.

Title: Toroidal continuously variable transmission
Inventor: NAKANO MASAKI
IPC: F16H15/38
Filed: 1988-03-12
Abstract: PURPOSE:To improve the torque transmission efficiency in the title transmission by providing a rotational friction reducing means between a preloading means and a disk abutted thereon, or between the preloading means and a pressing means or attachment shaft. CONSTITUTION:In transmitting a torque from an input shaft 12 to a first input disk 22, a loading cam 37 (pressing means) is operated while generating a phase deviation between a cam flange 34 and the first input disk 22, so as to press the first input disk 22 in the direction of a first output disk 24 and also press a second input disk 22a in the direction of a second output disk 24a. In this case, since a needle thrust bearing 110 is provided between a disk springs 100, 102 and the cam flange 34, a frictional resistance caused in the relative rotation between the cam flange 34 and the first input disk 22 is remarkably reduced. This causes the cam 37 to achieve the function thereof and produce an optimum pressing force previously set, thus preventing a first and second frictional pieces 26, 26a from being slipped.

Title: Automatic equalizing system
Inventor: TSUNODA TOSHIHIKO
IPC: H03H11/04
Filed: 1979-05-15
Abstract: PURPOSE:To perform an easy automatic control for the transmission level in the automatic equalizing system for the loss frequency characteristics of the transmission line, by connecting one end of the 1st and 2nd veriable resistance elements each to the reference potential point to secure the common control for them. CONSTITUTION:When the resistances of the cable transmission lines are referred to as R11-R16 with the capacity to C respectively, voltage gain G(f) is shown by equation 1-(3). The right half side of the equation functions as part of the flat control, and the gain becomes maximum when variable resistance R12 is infinite. And then the gain reduces as the resistance value decreases. On the other hand, the latter half of the equation shows the slope gain in that the gain in the low frequency region is low when variable resistance R15 is infinite and then the gain increases as the frequency increases. Here one end of resistances R12 and R15 each is connected to the earth functioning as the reference potential point to be controlled in common along with the control directions made identical to each other. Thus an easy automatic control is performed for the transmission level.

Abstract: PURPOSE: To protect a rotor from damage due to side shafts by maintaining a rotor in the center position by installing a distributing valve which supplies a  quantity of oil in propotion to pressure of each passage provided at the both sides of a rotor that face to a cylinder.  
     CONSTITUTION: Supposing that a rotor 5 has moved to a backwall 3 during rotation, then opening of a ring-shaped oil groove 18a is narrowed by the rotor 5, and oil pressure in the groove 18a and an oil passage 18 is transfered through an oil pressure detecting pilot 20 to one end of an oil distributing valve 19. While an opening of another ring-shaped oil groove 17a is widened by the rotor 5, and oil pressure drops immediately. It is transfered through an oil passage 17 and an oil pressure detecting pilot 21 to the other end of the valve 19 which detects pressure difference between the passages 17 and 18 and moves downward for increasing an opening area of passages 19a and 18 resulting increase in pressure to the passage 18. Thus the rotor 5 is pushed back to the center position through the oil groove 18a by this pressure.
