Title: Diaphragm
Inventor: ARAI HISAHARU
IPC: F16J3/02
Filed: 1978-12-26
Abstract: PURPOSE: To produce a diaphragm which is superior in durability and uniform in strength without directional tendency of failure, by covering at least one side of thin base cloth, which is uniform in strength in all directions normal to its surface, with thin rubber film.  
     CONSTITUTION: One or both sides of base cloth 1, made of cotton plain woven or tricot fabric, is or are thinly coated with rubber 2 and vulcanized to form a diaphragm. The base cloth 1 may be a soft sheet like non-woven fabric, numberless fine fibers getting interwined along a plane so that it is uniform in all directions normal to the plane, or may be a sheet made of chemical material such as nylon. This diaphragm deforms uniformly at the time of action, which can eliminate coming off of the rubber layer or failure of the base cloth caused by local wrinkles and can improve the life expectancy of the product.

Title: Driver for oscillatory actuator
Inventor: GONDA TSUNEMI
IPC: H02N2/00
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To minimize unevenness of velocity by generating oscillations which oscillate in parallel with the direction of the driving force by applying a frequency signal set so that the relative motion reaches a specified velocity to an electromechanical converting element for the drive, and oscillation which oscillates in the direction crossing this, thereby controlling the frequency signal. SOLUTION: The frequency from an amplifier 5 for drive is supplied to a piezoelectric element for longitudinal oscillation of an oscillatory actuator 10, and the frequency signal from an amplifier 6 for drive is supplied to the piezoelectric element for torsional oscillation of the oscillatory actuator 10. In the case of switching the rotational direction of the oscillatory actuator 10, the phase of the output signal from a phase shifting circuit 4 is inverted. Then, a longitudinal oscillation detection signal processing circuit 7 processes the output voltage from the piezoelectric element for the detection of longitudinal oscillations, and extracts a rotation unevenness signal. Moreover, the control of the torsional oscillation detection signal processing circuit 8 corrects the divergence between the set rotational velocity and the average value of actual rotational velocity.  As a result, the rotational unevenness can be kept to a minimum.
