Title: Voltage amplitude limiting circuit
Inventor: KUMAGAI KAZUHIKO
IPC: H03G11/00
Filed: 1983-01-31
Abstract: PURPOSE:To remove the influence of the internal impedance of a reference power source and a voltage drop across a diode which feeds the output of one amplifier back by connecting the reference power source to the operational amplifier and the diode to a signal line. CONSTITUTION:Signal-source elecromotive force ES is inputted to the inverted input terminal of an operational amplifier Z1. When this voltage is higher than that of a reference power source Vh, the diode D1 is biased forward to perform amplitude limiting operation. When the input voltage is lower, the diode D1 is biased reversely, so the signal is transmitted as it is. The trailing operational amplifier Z2 performs the same operation with the leading operational amplifier Z1 when the input voltage is minus. Therefore, almost no current from the reference power source is consumed, so the need to reduce the internal impedance of the reference power source is eliminated, a variable rsistor is usable, and the diode is in a negative feedback loop, so the influence of the voltage drop is eliminated.

Abstract: PURPOSE:To miniaturize a discriminator, to make it suitable for IC-implementation, and to detect a bit period on a low-quality communication circuit PSK communication system stably at a high speed, by providing a bit synchronizing pulse generator. CONSTITUTION:Bit synchronizing pulse generator 9 is provided and controls up and down operations of detecting counters 7 and 8 for a difference between a leading phase and lagging phase, and clocks generated by generator 9 are controlled by overflow signals of counters 7 and 8. Namely, when counter 7 overflows, one clock of generator 9 is added and its output leads in phase by one clock. When output signal F of generator 9 is out of phase with output signal E of code-conversion point detection circuit 4, F is led into E in terms of phase at a high speed and becomes steady where the possibility that the pulse of E is generated is the highest; and then, counters 7 and 8 count down and the possibility of a transition into an error phase becomes smaller, so that a stable state can be obtained.

Filed: 1984-01-30
Abstract: PURPOSE:To obtain a constant discharge flow rate without correcting the applied voltage by restricting, at normal temperature, the amplitude of a pump which uses a vibration element made of piezoelectric porcelain thin plate by an adjusting member. CONSTITUTION:An insulating packing 10 made of urethane resin, rubber, etc. is installed onto the wall of a pressurizing chamber 4, and a unimorphic vibration element 1 which is formed by applying a piezoelectric porcelain thin plate 2 and a metal thin plate 5 onto the oter surface of the packing 10 is installed, and an amplitude adjuster 12 for resticting the amplitude of the vibration element 1 to a small value at a temperature in the normal-temperature range is installed into the pressurizing chamber 4, and the discharge flow-rate is reduced. At a low temperature in other-temperature range, the vibration element 1 is bent outwardly by the difference of thermal contraction between the piezoelectric porcelain thin plate 2 and the metal thin plate 5, and the amplitude adjuster 12 can not restrict the amplitude. Therefore, even if the viscosity of working fluid varies or the temperature characteristic of the vibration element 1 varies because of low temperature, the amount of discharge flow can be made constant as a whole.
