Title: Pll frequency synthesizer for complex communication system
Inventor: MATSUMOTO EIJI
IPC: H03L7/23
Filed: 1995-06-16
Abstract: PURPOSE: To provide a miniaturized PLL synthesizer for complex communication system where the transmission signal outputted from a PLL frequency synthesizer loop for transmission is stably modulated but the IF reference signal outputted from a PLL frequency synthesizer loop for reception is not modulated by a modulating signal. CONSTITUTION: This device is so constituted that the oscillation frequency of a VCI 4 for transmission which is modulated by a modulating signal 17 and is divided by a variable frequency divider and the reference frequency of a reference oscillator 7 which is modulated by the signal 17 and is divided by a fixed frequency divider approximately coincide with each other. Consequently, the output of an LPF 5 for transmission is not varied, and the output obtained by modulating the oscillation frequency of the VCO 4 by the signal 17 is a transmission signal as it is. In the frequency synthesizer loop for reception, the reference frequency of the oscillator 7 is modulated by the change of the modulating signal 17 to fluctuate the frequency, and the output of an LPF 9 for reception is fluctuated.  Thus, the signal 17 and the output of the LPF 9 differentially act upon a varactor diode incorporated in a VCO 8 for reception, and a difference voltage is not generated, and the reception synthesizer signal is not affected by the signal 17.

Filed: 1985-07-10
Abstract: PURPOSE:To eliminate the need for the time required for controlling the equalizing of voltage by controlling the set voltage of a voltage setter for an automatic voltage regulator so as to approximately coincide with system voltage before a synchronous machine generates voltage. CONSTITUTION:A voltage equalizer 22 is operated before the time when a field circuit breaker 3 is closed and a synchronous machine 1 generates voltage. Consequently, even when the initial set value VRO of a voltage setter 11 largely differs from power system voltage VL, the set value VR of the voltage setter 11 is made approximately the same as the voltage VL of a power system 15 before the field circuit breaker 3 is closed by the operation of the voltage arranging device 22. Since ¦VL-VR¦<DELTAV previously holds regarding the set value VR of the voltage setter 11 at the time t0, ¦VL-Vg¦<DELTAV holds regarding voltage Vg where the synchronous machine 1 is stabilized at the time t2, thus satisfying voltage conditions in a synchronism detector 17.

IPC: H05H13/04
Filed: 1987-06-18
Abstract: PURPOSE:To have frequently repeated operation by using a resonance power supply as a power supply for excitation of an electric magnet, and by using the positive and negative waveforms in resonance to acceleration of electron beam. CONSTITUTION:An electron beam emitted by a linear accelerator 1 is deviated upward by a beam distributing magnet 4 and irradiated to a synchrotron 2. Electric magnets of this synchrotron 2 are excited in sinusoidally wave by a resonance power supply composed of a charging power supply 6, a capacitor 6, and a load for electric magnets. The electron beam irradiated at this time passes another beam distributing magnet 5 to be irradiated to an accumulator ring 3 and accumulated there. Then the electric magnets are demagnetized sinusoidally and vibrated in the opposite direction. Then the electron beam emitted by the accelerator 1 passes the magnet 4 and is deviated downward to be irradiated to the synchrotron 2. The electrons are accelerated while turned reversely with excitation of the electric magnets, and upon attaining the final energy, irradiated to the ring 3 to be accumulated. This process is repeated to provide accumulation of large current at the ring 3.

Filed: 1995-06-16
Abstract: PURPOSE: To prevent the generation of spillage of toner by vapor-depositing a metal on a base material of a sealing member to prevent the waveness of the sealing member and keep the contact property with a photoreceptor. CONSTITUTION: The sealing member 4 is composed of a base material formed out of an urethane rubber, a silicone rubber or a material having an adequate elasticity and a metal such as aluminum is vapor-deposited on the surface. The thickness of the metallic layer of aluminum or the like is sufficiently thin compared with the base material, for example, is 2-6μm compared with 0.2mm of base material thickness and the ratio of the thickness of the aluminum layer to that of the base material is preferably controlled to 1/10000 to 3/10000. Vacuum-deposition is used as a method for vapor-depositing aluminum on the base material.  In such a case, since the surface of the sealing member 4 is covered with the conductive metal, the charge of an electrostatic latent image remaining on the surface of the photoreceptor after transferring is released out of the photoreceptor by the conductivity of the metallic layer on the sealing member 4.
