Filed: 1983-06-14
Abstract: PURPOSE:To provide the titled apparatus equipped with an air compressing means and a pressure chamber for injection of heat-sensitive ink thermally molten by a heating element toward a recording member under air pressure without a heat-sensitive inkfilm or ink reapplying mechanism. CONSTITUTION:Heat-sensitive ink 7 is heated and molten by turning on electric pulses to electrodes 6 at both ends of a heating element 4.

Title: Control process for analog/digital conversion
Inventor: UENO MASAHIRO
IPC: H03M1/52
Filed: 1983-06-13
Abstract: PURPOSE:To perform the A/D conversion of a bipolar input signal with one of reference voltage by deciding the polarity of the input voltage and controlling the polarity of the output voltage of an integration circuit so that said polarity is always set in the same direction. CONSTITUTION:When positive input voltage Vi is applied to a voltage input circuit 1, switches 20 and 22 of a switched capacitor circuit 19 are actuated alternately by a polarity deciding circuit 37 and a control circuit 36. The voltage Vi is then transferred to a capacitor 16 as the negative charge to be integrated for a fixed period of time. Then the positive reference voltage Vr is integrated by the circuit 19 and an integration circuit 3. If the voltage Vi has the negative polarity, the switches 20 and 22 of the circuit 19 are actuated in the same phase by the circuits 37 and 36. Thus the voltage Vi is transferred to the capacitor 16 as the negative charge. In such a way, a bipolar input signal can undergo the A/D conversion with one kind of reference voltage Vr.

Abstract: PURPOSE:To apply an analog or digital electric signal to a transducer by switching the mode wherein a single analog signal is applied to all bit electrodes uniformly and the mode wherein signals of respective digits of a PCM signal are  applied to respective bit electrodes individually. CONSTITUTION:When a contact (c) of a switch 8 is connected to a contact (a) by controlling a switching circuit 7, a PCM signal (digital signal) is supplied as parallel data to bit electrodes 13-18 through input terminals 1-6 and the switch 8. As a result, the free end of a piezoelectric type displacing flat plate 10 is displaced by an extent which corresponds to the PCM signal to drive a diaphragm 20.

In this case, the same signal is supplied to said electrodes 13-18, which equivalently results in that the analog signal is supplied to a normal piezoelectric type displacing flat plate having the one-sheet electrode consisting of the bit electrodes 13-18.
