    摘要： A printing head for an ink jet printer is provided with a plurality of ink jet sets. Each of the ink jets. Each of the ink jets includes an ink nozzle through which ink is ejected; a pressure chamber communicated with the ink nozzle and having a diaphragm made of a flexible plate; and a piezoelectric member bonded on an outside of the diaphragm for deforming the diaphragm to eject ink through the ink nozzle from the pressure chamber. The piezoelectric member includes a layer, having titanium an upper PZT layer chemically bonded on an upper surface of the titanium layer and polarized in a first direction; and a lower PZT layer chemically bonded on a lower surface of the titanium layer and polarized in a second direction opposite to the first direction. The titanium layer includes an interconnecting member and titanium members interconnected to each other by the interconnecting member forming a single titanium plate comb having teeth corresponding to the titanium members extending from two sides of the interconnecting member.

    摘要： Conveying devices, operation of which is stopped during printing, are provided upstream and downstream, as seen in a direction of conveying of a paper, of a platen arranged to face a printing head. The platen is provided with an electrostatic attraction member electrostatically the paper by the application of a voltage. A first control applies the voltage to the member during printing until a leading end of the paper arrives at the downstream conveying device. A second control applied the voltage to the member during printing after conveyance of a trailing end of the paper by the upstream conveying device is completed. Thereby, lifting of the end portions of the paper away from the platen is prevented, thus avoiding unprintable margins at such end portions of the paper.

    摘要： An apparatus for generating clock pulses comprises a Colpitts-type quartz crystal oscillator having an inverter composed of a C-MOS integrated circuit, and a quartz-crystal resonator connected with said inverter, and an amplifying circuit for amplifying the output of said quartz-crystal oscillator and delivering clock pulses as output. A first resistor is provided between the input terminal of the inverter and the quartz-crystal resonator, and the input terminal of the inverter is connected with the input terminal of the amplifying circuit. The amplifying circuit is for connection with a load composed of TTL circuits. This amplifying circuit includes a capacitor for suppressing a direct-current bias voltage from the output of the oscillator, an inverter composed of a C-MOS integrated circuit for providing the clock pulses as output, and a negative feedback circuit which utilizes negative feedback to the inverter as a direct-current bias voltage corresponding to the duty ratio of the clock pulses. This apparatus may further comprise a power supply for supplying operation voltage to the amplifying circuit which matches that of the load.
