Title: Pll circuit
Inventor: KITAZONO SHINICHI
IPC: H03L7/093
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To reduce leakage current and to improve operation stability by outputting an oscillation signal at the set frequency, comparing the phase of the oscillation signal with the phase of a reference signal, generating first or second current in accordance with a phase difference signal, stopping the generation of first and second currents when they are in-phase and supplying a voltage signal corresponding to current as a control signal. SOLUTION: A phase comparison circuit 10 compares the phase of a frequency dividing signal S50 from a programmable frequency dividing circuit 50 and that of a frequency dividing signal S70 from a reference signal frequency dividing circuit 70 and outputs an up signal Sup or a down signal SDW in accordance with a phase difference. A charge pump 20a adjusts the level of an output signal S20 in accordance with the up signal SUP or the down signal SDW from the phase comparison circuit 10. A loop filter 30 attenuates the high frequency component of the output signal S20 of the charge pump 20a and outputs a control signal S30 formed only of a low frequency component. VCOS 40 controls the oscillation frequency in accordance with the signal level of the control signal S30 from the loop filter 30.

Inventor: SATOU MAKOTO
IPC: G05F1/10
Filed: 1978-12-29
Abstract: PURPOSE: To secure the steady accuracy for the output current through operation given via the multiplier and the divider among the output current of the output current detector, the output voltage of the output signal voltage detector and the output signal current of the comparator each and then applying the output current to the control transistor.  
     CONSTITUTION: The output signal current of DC power source 1 is compared 7 with the reference signal current given from reference voltage setter 6, and then the ratio is controlled by the difference signal current of the both signals for the conducting current of control transistor Tr2. In other words, the output current and voltage are detected via output current detector 10 and output voltage detector 12 which are installed to the output circuit of Tr2, and at the same time a comparison is given via comparator 7 between the output signal current and the reference signal current. Thus the difference signal current is delivered. Then composite signal current Δ sI 0 /E 0  is delivered via multiplier 13 and divider 12 with output voltage E 0  of detector 12 as well as output signal current I 0  of detector 10 applied as output signal Δs of comparator 7. This output current is used as the control signal current of Tr2. Thus the steady accuracy is secured for the output current regardless of a big change of the load.

Title: Operation control device and operation controlling method for thermal accumulation type air conditioner
Inventor: MASUI TSUNETOSHI
IPC: F25B5/00
Filed: 1989-06-23
Abstract: PURPOSE:To suppress a rise in a saturation temperature corresponding to an evaporating pressure and prevent a reduction in an amount of ice production a method wherein during a normal cooling and an accumulated cold heating, a maximum degree of opening of a main pressure reduction value is set to a predetermined second maximum degree of opening smaller than the first maximum degree opening during the normal cooling operation. CONSTITUTION:When a normal cooling operation under a changing-over of a changing-over means 51 and an accumulated cold heating are performed simultaneously, a maximum degree of opening of a main pressure reducing valve 6 is set to a predetermined second maximum degree of opening smaller than the first maximum degree of opening when the normal cooling operation is carried out by a maximum degree of opening setting means 52 so as to restrict an increasing of a saturation temperature corresponding to an evaporation pressure. A difference between a refrigerant temperature within a thermal accumulating cold heat pressure reducing mechanism 14 and a water freezing temperature is made sufficient so as to prevent a reduction of an amount of ice. When the saturation temperature corresponding to the evaporation pressure detected by the sensor means 53 is more than a set value, the maximum degree of opening of the main pressure reducing valve 6 is set to a smaller third degree of opening than the second one. A rise in the saturation temperature corresponding to the evaporation pressure caused by the increase of the cooling load is suppressed so as to get a sufficient amount of ice. In this way, it is possible to eliminate a drawback caused by a size of the cooling load.

Abstract: PURPOSE:To decrease a saturated charge amount of a resin roller suitable for conveying a photosensitive material, in the resin roller constituted such that an axial end, provided with an axial core, is fitted to both ends of a metallic pipe, having a resin layer, by electrically conducting the metallic pipe to the axial core. CONSTITUTION:A pin 13 is driven from a main unit 11' of a phenol roller 10A, an example of resin roller, into an axial core 12A of a shaft end 12, to conduct a metallic pipe 11A to the shaft core 12A. If a surface of a resin layer 11B' is charged negative, a positive charge is induced to the outside of the metallic pipe 11A, and its corresponding negative charge is moved to the shaft core 12A through the pin 13. Then with the lapse of time about two seconds, all of the layer 11B', metallic pipe 11A and the shaft core 12A are charged negative by conductivity of resin as shown by B in the drawing. In this way, a saturated amount of charge in the roller 10A is decreased, while attenuation of charge voltage is increased due to natural emission and the like of an electric charge from an edge part of the shaft core 12A to the atmosphere.
