Abstract: PURPOSE:To control an output current and to eliminate variance at every bit by providing plural arrays of cascaded current mirror circuits and current control circuits on their input sides, interposing switch circuits in the middles of the cascaded circuits and turning on and off their output currents by arrays, i.e. bits.

Then, collectors of the TRs Q1...QN are connected to output terminals. When the TRs Q1-QN, and Q(N+1) of the current mirror circuits are equal in size and current amplification factor beta, the input/output current ratio (mirror ratio) is expressed by IO/II=(beta<2>+beta)/(beta<2>+beta+N+1) and when N<beta, the mirror ratio is extremely close to 1 (I0: I01...I0N), Namely, those current mirror circuits are cascaded to obtain an extremely stable current gain and switch circuits SW1...SWN are turned on the basis of data VD1...VDN to turn on and off the output current.

Title: Method for driving on-demand type multi-nozzle ink-jet head
Inventor: TORII TAKUJI
IPC: B41J2/055
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration in speed of liquid drops because of crosstalks and in ink amount, by prohibiting a voltage from being impressed between electrodes of a laminate piezoelectric element in a standby state without ink jetted, impressing the voltage between the electrodes when the ink is jetted, and removing a voltage difference thereafter. SOLUTION: A vibrating plate 3 and a restrictor plate 10 are formed of, e.g. stainless material and an orifice plate 12 is formed of nickel material. A head substrate 6 is formed of an insulating material such as ceramics or the like. In a standby state when ink is not jetted, a voltage between two electrodes is zero. In this case, a d33 laminate type piezoelectric element is not shifted. When the ink is jetted, a voltage that provides an opposite potential to a normal potential is impressed to the two electrodes to contract the piezoelectric element. As a result, the d33 laminate type piezoelectric element is contracted, so that the ink is sucked into a pressure chamber through a restrictor from an ink feed path.
