Title: Clock oscillation circuit
Inventor: NAKANO SHIGEYOSHI
IPC: H03K19/096
Filed: 1985-01-09
Abstract: PURPOSE:To constitute easily a system with less power consumption by providing the circuit stopping generation of the clock of a basic clock oscillation circuit or inhibiting an output therefrom and a circuit releasing the stop or inhibition. CONSTITUTION:When power is applied, an initial state setting circuit 6 is activated to initialize a selection circuit 3 and a release command circuit 5 so as to allow the basic oscillation circuit 1 generating a clock signal to make oscillation. The circuit 3 inhibits the output of the clock from a clock output circuit 2 until the oscillation of the circuit 1 is stabilized and when the oscillation is stabilized, the circuit 2 outputs the clock. When signals I2, I3 are inputted in this state, an inhibition circuit 4 generates a signal stopping the clock signal or inhibiting the clock output. The operation of the signal is decided depending on the state of the input signal I1 so that the oscillation of the circuit 1 is stopped or the output at the circuit 2 is inhibited. When a signal I4 is inputted in this state, the circuit 5 generates a signal stopping oscillation or releasing the clock output inhibiting state to output the clock signal.

Title: Half-wave rectifier circuit
Inventor: TONO KATSUHIKO
IPC: H02M7/21
Filed: 1994-01-17
Abstract: PURPOSE:To obtain a half-wave rectified signal whose distortion is small by a method wherein the output of a delay circuit is compared with a second reference voltage, the phase difference of the output of a switching circuit is compared with that of the output of the second reference voltage and the delay current of the delay circuit is controlled. CONSTITUTION:A comparator 2 compares an input signal (a) with a reference voltage 1, and it outputs a pulse signal (c). A switching circuit 3 outputs the output signal (b) of a delay circuit 1 at the input signal (a) when the pulse signal (c) is at 'H', and it outputs the reference voltage 1 when it is at 'L'. Then, the phase difference of the output (f) of a comparator 4 which has compared the output (b) of the delay circuit 1 with the reference voltage 2 and that of the output (g) of a comparator 5 which has compared the output (d) of the switching circuit 3 with the reference voltage 2 are detected by a phase comparator 6. The delay amount of the delay circuit 1 is controlled by its detection signal (h). When the delay amount is controlled until the delay of the comparator 2 and that of the switching circuit 3 become equal to the delay amount of the delay circuit 1, the distortion of a half-wave rectified waveform (d) can be reduced.

Title: High voltage power source
Inventor: SUZUKI KOUJI
IPC: H02M3/338
Filed: 1982-01-14
Abstract: PURPOSE:To obtain accurate limiting function in a high voltage power source by allowing an output voltage control loop which limits an output voltage at the prescribed value at the time when a load impedance increases to relate to a control loop which maintains the load current constant. CONSTITUTION:When the output power of an attenuator 20 exceeds the prescribed value, and the output of a comparator OA2 is inverted to turn a transistor Tr1 ON, thereby interrupting the input to the primary side power feeding circuit of a transformer T1 by the output of a differential amplifier OA2. Charge stored in a condenser C3 is discharged upon interruption of this input, the output of the comparator OA2 is again inverted to the original state, thereby turning the transistor Tr1 OFF. When the output of the transformer T1 tends to exceed the limit value which is determined by the Zener voltage of a Zener diode ZD1, the transistor Tr1 repeats ON and OFF and maintains the output of the transformer T1 at the limiting value.

Title: Ink jet recorder
Inventor: TAKEMOTO TAKESHI
IPC: B41J2/02
Filed: 1978-01-18
Abstract: PURPOSE:To prevent position deviations of printing points by letting the rise times of driving waveforms change with respect to high and low of the vibrating voltage being applied to a vibrating means and evening the flying speed of ink particles irrespective of the sizes of the particles. CONSTITUTION:As the speed of ink particles is increased in the case of a low voltage applied to a vibrating means, the rise times of the driving waveforms to be applied to a piezoelectric element are shortened. Namely, by changing the rise times DELTATC, DELTATD, DELTATE in such a way that the curves of the rise of the respective driving waveforms C, D, E, approximately unify, the displacement accelerations of the diaphragm become approximately the same even at the high driving voltage and low driving voltage. When the displacement acceleration of the diaphragm and the flying speed of the ink particles are not linear owing to the viscosity of ink, etc., the driving waveforms are selected in compliance with the characteristics of the head. Thereby, the flying speed of the ink particles may be evened and the position deviations of the printing points may be prevented.
