Title: Liquid crystal display body for heat writing
Inventor: MIYAJI YUKIO
IPC: G02F1/133
Filed: 1983-02-07
Abstract: PURPOSE:To obtain a liquid crystal display body for high-speed heat writing with use of an inexpensive transistor by using a heating means to preheat a substrate. CONSTITUTION:For a heating electrode device of a heat writing display body which heats up the liquid crystal via a heating electrode, transistors (TRs) 10- 10<n> supply the electric power to TRs 11-11<n>. The waveforms of these TRs 10- 10<n> are conventionally rectangular, and the electric power is generated only when the writing is carried out with the heating electrode. For this invention not only the rectangular waveform but the steady voltage is superposed and the waveforms are shown by 13-13<n>. The current always flows to the electrode owing to the steady voltage to heat up both the liquid crystal and the substrate even in the modes other than a writing mode. Thus a panel is always kept higher than a room temperature. If the substrate is preheated, the preheating is possible in a shorter time than a case where the electric power is supplied to an unpreheated panel with a power transistor of large output even though the electric power is supplied with a power transistor of small output.

IPC: G01S3/54
Filed: 1985-02-04
Abstract: PURPOSE:To obtain a highly sensitive Doppler type direction finder reduced in the arrangement circumference of antenna elements, by constituting said direction finder so as to change over four antenna elements arranged in four directions to the intersecting directions thereof. CONSTITUTION:For example, an antenna 1 is constituted of four dipole antenna elements N, S, E, W. A changeover device 2 performs the high speed changeover and take-out of antenna output on the basis of the changeover signal (a) from a changeover circuit 8 to obtain an azimuth signal (b). The signal (b) is amplified by an amplifier 3 and outputted as an azimuth component detection signal through an azimuth component detection circuit 4. The elements N and S, E and W arranged in the intersecting directions are combined as two sets and the signal (b) is obtained by the first changeover alternately and repeatedly changing over one set N and S several times, the second changeover for changing over the other set E and W are the third changeover for alternately repeating the first changeover and the second changeover. The phase change in this signal (b) at the time of each changeover is extracted by the circuit 4 to output a signal (c). The signal (c) at the time of each changeover is set as the distribution signal connected to four directions and directional indication is performed by an azimuth indicator 40.

Title: Feeding method for recording medium
Inventor: SAKURAI FUMIO
IPC: G11B15/48
Filed: 1984-02-02
Abstract: PURPOSE:To shorten the period of time required for stopping a recording medium and contrive to enhance printing quality, by impressing a reverse rotating field to a motor to brake the motor, when stopping the movement of the recording medium fed by forward rotation of the motor. CONSTITUTION:When feeding the recording medium for printing, a voltage Vcc is impressed on the motor 21. When stopping the feeding, a change-over switch 23 is operated on the basis of a stopping command signal, and a voltage -Vcc for generating a magnetic field in a direction opposite to the direction of the magnetic field generated by the voltage Vcc is impressed on the motor 21 for an appropriate period of time. As a result, a reverse rotating field is impressed on the motor 21, and the inertia generated in the forward rotation is canceled, whereby the motor is rapidly stopped. Accordingly, the printing quality can be enhanced.

Abstract: PURPOSE:To operate the device which can be operated by an operator without taking a painful posture, by cancelling the relative positional difference of a master arm and slave arm after moving the slave arm to the specific position with the addition of the relative difference in the positions of master arm and slave arm. CONSTITUTION:In case of an operator becoming difficult to operate a master arm 33, an offset in switch 38 is actuated and the master arm 33 only is moved to the position where the operator is easy to operate. A offset ON switch 39 is then actuated to find the difference in the position of the moved master arm 33 and the relative position of a slave arm 34. The slave arm 34 is moved to a desired position with the addition of this positional difference. On completion of the necessary work, an offset OFF switch 40 is actuated and the master arm 33 is returned in the same posture of that of the slave arm 34 again. Consequently, the operator becomes unnecessary for taking a painful posture during the operation and a quick and correct operation can be done.
