Title: Driving method for fine adjustment using piezoelectric element
Inventor: OKAYAMA SHIGEO
IPC: H01J37/28
Filed: 1988-12-23
Abstract: PURPOSE:To making the direction of a voltage applied to each piezoelectric element coincident with a polarizing direction at all times and to display performance which is stable for a long period by connecting a couple of piezoelectric elements of the same kind after polarization in series with each other and applying the connection part with a driving voltage which is opposite in phase from both piezoelectric elements. CONSTITUTION:The couple of piezoelectric elements 3a and 3b are coincident in electrode direction, the polarity of driving voltage applied to the piezoelectric elements 3a and 3b is coincident with the electrode direction, and bias voltages VB of the same level are applied in a normal state to cause displacement of LB as compared with when no voltage is applied to the piezoelectric elements 3a and 3b. When a probe 1 is displaced in an X direction, voltages +DELTAV and -DELTAV which are made opposite in phase by a couple of amplifiers 6a and 6b provided in front of the connection point of the piezoelectric elements 3a and 3b are added to the bias voltages VB respectively. Consequently, the length of one piezoelectric element 3a is LB+DELTALa and the length of the other piezoelectric element 3b is LB-DELTALb, so that the probe 1 supported between both piezoelectric elements 3a and 3b is put in slow motion smoothly in the X direction.

Abstract: PURPOSE:To enable (N-1)-addition without executing synthesis-analysis encoding unnecessary in almost all sound sections, and to eliminate the unwanted deterioration of sound quality. CONSTITUTION:The spectrum envelope calculators 216 of speech synthesizing parts 21 to 2n calculate the spectrum envelopes of each coded sound signal inputted to input terminals 11 to 1n.

Title: Elastic clutch
Inventor: HANKE WOLFGANG
IPC: F16F15/16
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To reduce the damage occurring to each cam face by making a peripherally mobile cam portion movable against the force of a spring, and forming a buffer chamber between a fixed cam portion and the mobile cam portion. SOLUTION: A second cam is formed into a special shape, and force is increased at the last of distance. The figure shows a spring characteristic curve, the horizontal axis indicates distance, and the vertical axis indicates force. The spring characteristic curve has a relatively flat curve in a region A, and it has a steep curve in a region B. The steep curve is caused by the action of an additional spring. The additional spring is compressed before two stopper faces are brought into contact with each other in the final region of the relative movement between two clutch portions. Buffering in the region B for two cam portions can be increased by making the buffer gap of the second cam narrower than the buffer gap of a floating buffer ring. The cross section of a buffer chamber is increased, thus resulting in an increase of buffering.
