Title: Driving circuit of piezoelectric ink jetting head
Inventor: IWAKURA YOSHIKI
IPC: B41J2/045
Filed: 1993-04-23
Abstract: PURPOSE:To print at a very high speed under the condition that high printing quality is maintained by a method wherein driving circuit is so constituted as to make the time constant of the discharge voltage of a piezoelectric crystal element longer than the time, during which the specified switching means is ON, in the minimum driving period of the driving circuit. CONSTITUTION:The driving circuit concerned is equipped with a first switching means 1 for opening and closing the charging flow path of a piezoelectric crystal element 7 and a second switching means 3 for opening and closing its discharging flow path so as to compress a pressure chamber in order to discharge ink through nozzles for printing. In the driving circuit of a piezoelectric ink jet head of this type, a driving circuit is so constituted as to make the time constant CR2 of the discharge voltage of the piezoelectric crystal element longer than the time, during which the second switching means 3 is ON, in the minimum driving period of the driving circuit. Thus, the driving voltage is virtually lowered and the increase of the diameter of ink drop in high frequency driving is suppressed, resulting in allowing to contrive to homogenize printing dots. As a result, high speed printing can be possible under the condition that high printing quality is maintained.

Filed: 1981-07-30
Abstract: PURPOSE:To obtain an inexpensive electric contact material with high capacity, by sintering a material comprising W to which a specific amount of Ni and B at a specific temp. range under hydrogen atmosphere in a non-carbonization furnace. CONSTITUTION:The material composition of a sintered electric contact material consists of, on the wt% basis, 5-20 Ni, 0.05-1B and the remainder of W and this material is sintered at 1,300-1,350 deg.C under hydrogen atmosphere in a non- carbonization furnace. Ni is added in a range of 5-20% because said electric contact material becomes too brittle if 5% or less as well as strength thereof is insufficient even if B is added and, if 20% or more, the wearing thereof becomes remarkable. On the other hand, if the amount B is 0.05% or less, there is no effect in the enhancement of strength and if 1% or more, the strength thereof is lowered. The non-carbonization furnace is used in sintering because the active sintering force of a ferrous element becomes insufficient in the presence of carbon.
