Title: On-demand type ink jet print head
Inventor: OYAMA NORIKO
IPC: B41J2/16
Filed: 1990-08-20
Abstract: PURPOSE:To form an appropriate piezoelectric element array to be arranged in an ink tank and allow generation of ink droplets with a sufficient scattering capability even at low voltage by laminating a piezoelectric material over a conductive material alternately in the form of a laminated layer, then baking them to form a piezoelectric element array and arranging a partition member between piezoelectric elements. CONSTITUTION:A partition member 10 is formed between piezoelectric elements 12, 12... which constitute a piezoelectric element array. An independent cable 6 is connected to an external conductive layer 60 to which one electrode is connected, while a common lead member is connected to an external conductive layer 62 to which the other electrode is connected. When an electric signal is connected to an area between the independent cable 76 and the common lead member, piezoelectric materials 34, 34, 34... become elongated simultaneously between the electrodes, if the signal is selectively connected to the independent cable 76. Subsequently, the displacements of the piezoelectric materials in the layers are added together to displace the free end 12a side in 'X' direction. A voltage applied to an area between electrodes 30, 32 has only to be at an extremely low level.

Abstract: PURPOSE:To easily vary an output while keeping high power efficiency by providing a multilevel direct current signal generation circuit, which inputs a signal to set the average output level of a high frequency power amplifier and generates a direct current signal corresponding to the input value, and a multiplier circuit to multiply the output of this multilevel direct current signal generation circuit to the output envelope of an envelope generating means. CONSTITUTION:A designated signal input terminal 12 inputs an output level designation signal to be outputted to a transmission output terminal 6 corresponding to a transmission output level. A multilevel direct current signal generation circuit 80 generates the direct current signal according to this output level designation signal. A multiplier circuit 9 multiplies the output of an envelope generation circuit 7 and the output of the multilevel direct current signal generation circuit 80. Thus, the output of the multiplier circuit 9 can obtain a signal in proportion to the envelope of a modulated wave and further, the average value is changed corresponding to the transmission output. A voltage control circuit 10 changes a drain bias voltage VD of a power amplifier 5 corresponding to the output of this multiplier circuit 9. As a result, the drain bias voltage VD is made proportional to the envelope of the modulated wave and the average value is changed corresponding to the transmission output.

Title: Ringing tone sending-out circuit
Inventor: TABU TAKASHI
IPC: H04M3/06
Filed: 1985-10-02
Abstract: PURPOSE:To suppress transition and to prevent a ringing tone transmission stopping function from malfunctioning and the impulse noise to an adjacent circuit from being generated by inserting a variable resistance into a subscriber line, and decreasing its resistance value gradually after the start of the transmission of a ringing signal and increasing it gradually right before the stop of the transmission. CONSTITUTION:A gate 17 generates the OR signal (c) between a calling control signal (a) and the output signal (b) of a time-limiting circuit 16 and a driver 18 drives a relay 9, so that its contact 4 operates at a point t0 of time and is reset at t2. The signal (a) is shaped into a signal (d) by the integration circuit composed of a resistance 11 and a capacitor 12 and the signal is inputted to a variable resistance element 15 through a buffer 14 and a resistance 11. Its resistance value R15 decreases gradually as the signal (d) increases and is held equal to a low resistance value RL after the signal (d) reaches a steady value. Consequently, a calling signal (r) sent out of a calling signal generating device 5 increases gradually after the operation point t0 of the contact 4 according to the gradual increase in the resistance value R15. The R15 is equal to the RL continuously up to a point t1 of time, but increases gradually according to the gradual decrease of the signal (d) and reaches a high resistance value RM by a point t2 of time where the signal (d) is ceased, so the signal (r) decreases gradually by the point t2 of time where the contact 4 is reset.
