Title: Phase locked loop oscillation circuit
Inventor: HAMADA TATSUYOSHI
IPC: H03L7/10
Filed: 1991-06-03
Abstract: PURPOSE:To control an operating frequency F to be F=f0 by devising a circuit such that a control is not stopped due to synchronism going out of a limit of the operating frequency F=f0+ or -DELTAf different from a conventional PLO circuit and no alarm is raised in a system on the way even when an input signal is interrupted. CONSTITUTION:A detection voltage representing an internal phase and that for an input signal phase are detected by a phase comparator 10 and its detection voltage is fed to a low pass filter 20, the result is amplified by an operational amplifier 30 and its output voltage is fed to a VCO section 50. The output signal of the operational amplifier in the phase locked loop oscillator circuit feeding back the output of the VCO section to the phase comparator is inputted to a phase change detection section 1 to detect whether or not the phase of the input signal is largely fluctuated, and the result of detection is inputted to a phase change discrimination section 2 with an input interrupt signal. When the input signal is interrupted or the phase is largely fluctuated, the output voltage is fed to the VCO section 50 by setting 0V to an analog switch 3 and the operating frequency F is automatically converged to f0, and when the phase is not largely fluctuated even in the case of the interrupted input signal received, the output voltage is fed to the VCO section 50 as it is.

Abstract: PURPOSE: To ensure a continuous operation of an automatic paper feeder with no hindrance, by pulling a support member for an auxiliary pile, from a zone between the auxiliary pipe and a main pile adjacent to the former, so as to bundle the auxiliary pile and the main pile. CONSTITUTION: Pulling motion of a support device 6 which holds an auxiliary pile 11 is continued until the level of the upper surface of the auxiliary pile becomes out of an error range relating to a delivery edge. The pulling motion is rested unless the support device 6 is completely pulled out, and until the level of the surface of the pile is retained out of the error range, but is restarted if the level of the surface of the pile falls again in the error range as a result of the pile lift-up motion.

Title: Ink jet printing head
Inventor: OGURO TATSUYA
IPC: B41J2/125
Filed: 1988-05-31
Abstract: PURPOSE:To miniaturize an apparatus by dispensing with an ultrasonic wave absorbing means, by generating an ultrasonic wave so as to negate the advance wave thereof by detecting said advance wave. CONSTITUTION:Ink is introduced into the ink chamber 8 of a cylinder 7 from an ink supply hole 2 to be injected from nozzles 3, 3.... When ultrasonic vibration is applied at this time by an ultrasonic exciter 19, an ultrasonic wave becomes an advance wave to reach the other end part of the cylinder 7. Since an ultrasonic wave detector 31 is provided to the other end of the cylinder 7, the ultrasonic wave A detected by the PZT ceramics 33, 34 of the detector 31 is converted to an electric signal which is, in turn, amplified by an amplifier 48 and, thereafter, noise is removed by a band-pass filter 49. The signal outputted from this filter 49 is inputted to a gain variable inverting amplifier 54 and a gain is controlled in a phase reversed state to be amplified. The output of the amplifier 54 is supplied to the PZT ceramics 37, 38 of an ultrasonic exciter 35 and the ultrasonic wave B corresponding to the output of the amplifier 54 is generated to negate the ultrasonic wave A. By this method, even when an ink droplet is formed stably and uniformly using the advance wave of an ultrasonic wave, an apparatus can be miniaturized.
