IPC: H04N3/26
Filed: 1989-05-25
Abstract: PURPOSE:To obtain a prescribed control signal in a simple constitution by synthesizing a parabolic wave of a horizontal cycle amplified up to a prescribed amplitude with a parabolic wave of a vertical cycle also amplified up to a prescribed amplitude via a clamp means. CONSTITUTION:A clamp means (diode D) is used together with the means (transistor TR Q1 and Q2) which amplify a parabolic wave (terminal T1) of a vertical cycle up to a prescribed amplitude and the means (TR Q3 and Q4) which amplify a parabolic wave (terminal T2) of a horizontal cycle up to a prescribed amplitude. Then the amplified output of the parabolic wave of the horizontal cycle is clamped by the amplified output of the parabolic wave of the vertical cycle for production of a prescribed control signal (terminal T3). Thus the parabolic waves of horizontal and vertical cycles amplified up to each prescribed amplitude are synthesized together by a clamp means D. As a result, a control signal of a prescribed high level of pressure is obtained in a simple constitution.

Title: Transmission right taking over system
Inventor: KOBAYASHI KOJI
Filed: 1986-06-10
Abstract: PURPOSE:To make data transmission efficient between communication equipments STA by shortening time required for relaying and switching a preferential right request signal and recognizing the way the transmission right is taken over and acquired through minimum signal exchange. CONSTITUTION:Each communication equipment STA delays a reception signal SR by about one bit to transmit it. In order to request the transmission right, said equipment STA transmits its own code instead of a received priority code if the received one is higher. If the communication equipment STA has the transmission right and a received transmission right request signal CT different from its own signal, it responds the different signal, transmits a taking over designation signal CT' showing the communication equipment that will take over the transmission right next time. Then it abandons the transmission right, while the other equipment relays the signal CT'. After the communication equipment that will take over the transmission right acquires the transmission right by receiving the signal CT', it transmits a recognition signal. The other equipment relays the recognition signal, and simultaneously recognizes the communication equipment that acquired the transmission right.

Title: Input circuit
Inventor: YOSHIDA TOSHIO
IPC: G05B19/408
Filed: 1981-08-27
Abstract: PURPOSE:To prevent malfunctions of a device, by preventing the output signal during chattering of an input set switch as well as an unnecessary output signal during the operation of the device from being inputted to an electronic controlling part. CONSTITUTION:Before the output of a start signal, namely, at the initial input set time, the output signal of a counter 7 is inputted to a memory 10 through a selecting circuit 9. Even if chattering is generated at a mechanical contact during the operation of an input set switch part 4, the signal outputted for this c hattering is not stored in the memory because a counter 7 does not output the first operation start signal. After the output of the start signal, the output signal of a timer 8 is inputted to the memory 10 through the circuit 9 during the operation of the device. The signal outputted from the input set switch part 4 and the chattering signal after the operation completion are not stored in the memory because the timer 8 does not output the second operation start signal.
