IPC: H02M3/28
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide highly stabilized output by detecting continuous or discontinuous current of inductor to apply the control algorithm suitable for respective operating conditions. SOLUTION: In a switching power supply, a control algorithm is changed for maintaining an output voltage to a constant value by following the change of input voltage and inductor current IL. The operating condition for an apparatus is determined, based on the detected digital data and that before one control cycle, and a command value calculation program is adequately selected depending on the operating condition. The inductor current IL becomes minimum, when the main switching element 42 is changed from being turned on to off state and becomes maximum, when it is charged from being turned off from turned on. Therefore, data is fetched in respective timings and a difference is obtained to detect the amount of change in the inductor current. When the main switching element 42 is turned on, the command value calculation program can be selected, depending on the operating condition by detecting the condition of the inductor current.

Filed: 1984-08-14
Abstract: PURPOSE:To reduce the number of turns of the second winding inserted in the current circuit together with the first winding connected therewith by guiding a signal generated in replay to the quantity of current flowing through the load- dividing circuit via a resistor. CONSTITUTION:Constant current circuit 2 detects current I1, I3 through each passages by means of the first winding WD1 and the second winding WD2 and the current I1 is controlled so that a voltage Vd corresponding to the total magnetic fluxes induced by both of the windings is equal to a reference voltage V0. Hence IL=I10-(N2/N1).I3 (N2 is the number of turns of the second winding WD2, N1 is the number of turns of the first winding WD1 and I10 is a constant). Current I3 is proportional to I2/R3 so that if the proportional constant is assumed to be G, the number of turn N2 can be reduced by increasing G/R3. In addition, characteristic of winding can be changed by changing the resistor R3.

Abstract: PURPOSE: To keep a sealing part of a container clean and to prevent the adhesion of foods by fastening a sprocket inner edge part to the center of a wiper disc device by a pin and unrotatably fixing an outer edge part thereof for preventing the drips from a filling machine from being dropped onto a seal lip. CONSTITUTION: When a group of nests 104 on which the container are loaded, are carried to a filling machine 10 by a chain, all the drips are dropped onto a wiper disc 150. For preventing the drips on the wiper disc 150 from being dropped onto a group of containers, a wiper arm 164 is rotatably fastened on the center of the wiper disc 150 by a pin. An outer edge part of the wiper arm 164 cannot be rotated with the wiper disc 150. As the wiper disc 150 is rotated in the direction opposite to the rotating direction of the filling machine 10, a front edge 168 of the wiper arm 164 guides the liquid or solid foreign matters in the direction of the outer peripheral edge of the wiper disc 150.

Abstract: PURPOSE:To eliminate the need for operating a selection switch by an operator and to improve the operation efficiency by providing a sensor which detects an edge corresponding to the size of a document setting part at the document setting part and selecting a form cassette corresponding to the size with the output of the sensor. CONSTITUTION:Photoelectric sensors 31 and 32 are in a copying machine main body 11 and cooperate with reflecting plates 41 and 42 of a platen cover 24 when documents of B4 size and A3 size are placed to stop the output by interrupting specific reflected light. Namely, A3 is decided when both sensors stop, B4 is decided when only the sensor 31 stops, and A4 is discriminated when both generate outputs. A selection part 50 detects the document size as mentioned above when the platen cover 24 is closed to select copying form cassettes 21, 22, and 23 of A4, B4, and A3 automatically. Therefore, the operator only depresses a start switch to take a copy on a copying form matching the document size.
