Title: Ultrasonic remote instruction controller
Inventor: TODA KOJI
IPC: G06F3/043
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To move an indication on a display screen through remote operation in a direction similar to the direction at the time of successively touching two areas on a non-piezoelectric board. SOLUTION: When an electric signal is inputted from an interdigital electrode T, an SH wave is excited to a double layer body structure composed of a piezoelectric substrate 1 and a non-piezoelectric board 2. This SH wave is converted into an electric signal by interdigital electrodes RY and R- Y but is not outputted. When four areas SYX, SY- X, S- TX and S- YX are touched from the upside of a sound absorbing board 4, however, electric signals are outputted at the interdigital electrode RY or R- Y and these electric signals are radiated on the display screen as radio signals. Thus, the indication on the display screen can be moved by remote operation in the direction similar to the direction at the time of successively touching two areas.

Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To simply peel a film according to treatment in a short time without requiring special equipment by immersing a can material sample having the surface covered with a covering film in a methyl acetate solution. SOLUTION: A can material sample having the surface covered with a covering film, especially the one having a steel sheet surface to which a biaxially oriented polyethylene terephthalate film (hereinafter referred to as a PET film) is bonded is immersed in a methyl acetate solution for preferably 3-5min and the film is then peeled. Furthermore, the temperature of the methyl acetate solution is preferably regulated to about ambient temperature of 10-30 deg.C. Although the film can be peeled simply by immersion for the side of the inner surface of the can material according to the method, the film can completely be peeled by a method for taking out the can manufacturing material from the methyl acetate solution, then bringing a tacky tape into close contact with the film covering the surface on the side of the outer surface of the can material for the side of the outer surface of the can material and pulling the tape.

Title: Signal processing circuit
Inventor: HONJO MASAHIRO
IPC: H03K5/007
Filed: 1986-09-12
Abstract: PURPOSE:To remarkably reduce waveform distortion of an output signal by feeding back a DC component of an output signal of a delay element receiving an FM signal negatively to an input bias voltage of the delay element so as to control the input bias voltage. CONSTITUTION:The FM signal inputted from the input terminal 1 receives a prescribed bias by resistors R1, R2 and is inputted to a delay element 2. The delay element 2 consists of series connection of, e.g., many C-MOS gates 6. Then the DC component is obtained from the input signal and the output signal of opposite polarity by using a resistor R4 and a capacitor C2 and fed back negatively to the input bias voltage via the resistor R3. When the input signal and the output signal of the delay element 2 are of the same polarity, an inverting circuit is inserted between the resistors R4 and R3. Thus, the waveform distortion in the output signal is reduced remarkably. The circuit is suitable for the signal processing system of a VTR.
