Filed: 1985-05-23
Abstract: PURPOSE:To enable a thin printer to be manufactured by providing a printing ink supply section in a gap between adjoining vibrators connected to a pectinated piezoelectric vibrator having a common electrode and a selective electrode mounted onn the opposed surfaces. CONSTITUTION:A line hand is composed of a piezoelectric vibrator 11 having a common electrode 9 and an optional number of selective electrodes 10 mounted in opposed position on a pectinated piezoelectric material 8, an ink supply section 12 containing printing ink and a drive circuit 6 to which electrodes 9, 10 are connected. Under this pectinated design, a gap is created between adjoining vibrators and ink is supplied from the ink supply section to the gap allowing ink to be fed to the end of the vibrator 11 by capillary action. Then a displacement vibration is generated on the vibrator 11 selected by choosing the selective electrode 10 required, thus transferring printing ink in the gap between the vibrators 11 directly to paper. In this way, it is possible to manufacture a thin line printer and improve its reliability.

Title: Ice making device
Inventor: DENPO KAZUO
IPC: F25C1/10
Filed: 1992-04-30
Abstract: PURPOSE:To eliminate useless power energization for a freezing prevention heater and save power energy. CONSTITUTION:Freezing prevention heaters 18 and 19 are installed to a water supply line which leads to an ice making pan 12 where power is energized by a drive signal from a control device. The control device detects a water supply state of the ice making pan 12 based on a temperature signal transmitted from a thermistor 17. A continuous closed time of a door 3a of an ice making chamber 3 is time-counted by the control device based on an opening/closing signal transmitted from a door switch. When both an empty state of a water supply tank 8 and the continuous closed time of the door 3a exceed 24 hours after water has been supplied, the control device determines that no substantial ice making operation is being carried out and cuts off the supply of power to freezing prevention heaters 18 and 19, which makes it possible to save power energy.
