Title: Ink jet recorder
Inventor: NAKA TAKAHIRO
IPC: B41J2/045
Filed: 1988-06-03
Abstract: PURPOSE:To obtain substantially constant printing density and thickness even if an ambient temperature varies by relatively accelerating the speed of ink particles injected from the ink injection nozzle of an ink jet head in a low temperature range as compared with that in a high temperature range. CONSTITUTION:When a charging pulse 16 is input to a charge signal terminal 15, a piezoelectric element 13 is abruptly charged through a charging resistor 18, ink in a passage is pressurized to fly ink particles 14. Then, when a discharging pulse 19 is input to a discharge signal terminal 17, the charge of the element 13 is gradually discharged through discharging resistors 18, 20, and returned to its original state. In this case, the speed of ink particles injected from a nozzle is accelerated toward a low temperature range. As a result, ink weight per one dot is so controlled as to approximate a substantial constant to the using ambient temperature. Then, it is always printed with constant density and thickness.

Title: Frequency synthesizer
Inventor: NOSAKA HIDEYUKI
IPC: H03B28/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To uniquely determine an output voltage level by starting integration at the same initial value at all the time by periodically resetting the output voltage of an integrator. SOLUTION: While using an integrator 5 with a reset circuit, an integrator 5 is reset by the output of a frequency divider circuit 20A for dividing the frequency of a clock. The frequency dividing ratio of the circuit 20A is determined, while considering the operating cycle of an accumulator 1 and is set equal with the operating cycle of the accumulator 1 or set to an integer multiple of that cycle. When te voltage of the integrator 5 at the moment to raise each clock is noticed, the same voltage is passed after the lapse of the operating cycle of the accumulator 1. For example, the output of the integrator 5, after resetting becomes an initial voltage but after the lapse of the operating cycle of the accumulator 1, is returned to the initial voltage for the first time.  Thus, the periodicity of the output waveform of the integrator 5 is not disturbed by resetting only, because when a reset cycle coincides with the integral multiple of the operating cycle of the accumulator 1.
