Title: Ultrasonic motor
Inventor: IWAO NAOTO
IPC: H02N2/00
Filed: 1990-02-19
Abstract: PURPOSE:To improve the stabilization of the operation of a motor and the efficiency of the same by making the magnitude of the amplitude of ultrasonic oscillation excited in an oscillating piece is made smaller than the size of the flatness of respective contacting surfaces of the oscillating piece and a movable piece. CONSTITUTION:The size of the amplitude of an ultrasonic oscillation, excited in an oscillating piece 11, is never made larger than the size of the flatnesses of respective contacting surfaces 19a, 19b of the oscillating piece 11 and a movable piece 13. When a movable piece 13, abutted against the oscillating piece 11, is moved relatively with respect to the oscillating piece 11, the oscillating piece 11 contacts with the movable piece 13 without effecting biased contact by the constitution described above. In this case, the contacting surfaces 19a, 19b can be abutted uniformly along the whole surfaces of the contacting surfaces 19a, 19b in the contacting surfaces 19a, 19b between a projection 16 and a contacting part 17. According to this method, the operation of the ultrasonic motor 10 can be stabilized in such a manner.

Title: Device to move scrambler for television signal
Inventor: KUROODO SHIYAPERU
IPC: H04N7/167
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To secure the confidentiality and safety required by a scrambling device by shifting the scramble circuit of a scrambler to a transmitting location from a generating location and obtaining the data element required by the scramble circuit at the generating location by holding a processing circuit at the generating location, and then, inserting the data element into coded compressed television signals transmitted to the transmitting location.

The scrambler 13 sends the data element synchronized to the video signals received through its input to the input of the coder CODec 12 which is called a service channel and lowered in bit speed. Digitally coded signals are transmitted to a link which connects the generating location 1 to a transmitting location 7 and has a slow bit speed as the output of the coder CODec 12, restored by means of a decoder coDEC 14, and added to the input of a shifted scrambler 15.

Title: Ink jet recording head and manufacture thereof
Inventor: MATSUZAWA AKIRA
IPC: B41J2/16
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent the resistance of an electrode from increasing with respect to a piezoelectric element by forming an electrode on the periphery of the piezoelectric element thinner than other parts. SOLUTION: In order to etch a diaphragm forming compliance selectively, a negative resist pattern is formed on a common electrode 3 not facing an ink chamber. More specifically, a resist pattern 102 of same thickness is formed in order to protect a piezoelectric element 4 and the common electrode 3. The surface on which the piezoelectric element 4 is formed is then etched by ion milling. A common electrode 3 in the peripheral region 104 of the piezoelectric element 4 where the resist pattern 102 is not formed is etched selectively to decrease the thickness. Since the etching is ended while leaving the resist pattern 102 by a small thickness, the common electrode 3 keeps the original thickness under the piezoelectric element 4 and above a silicon substrate 106 thus preventing the resistance of the electrode from increasing.
