IPC: H02M7/04
Filed: 1981-10-30
Abstract: PURPOSE:To reduce the power consumption of the multioutput power supply as well as to contrive improvement in operational efficiency of the titled power  supply by a method wherein the dummy resistor of the multioutput power  supply, with which a stabilized output and a non-stabilized output will be obtained, is connected in between a stabilized terminal and a non-stabilized terminal. CONSTITUTION:The output of a conversion transformer 2 is supplied to load LA and LB as non-stabilized outputs EA and EB through the intermediaries of a diode 3 and a capacitor 4, and, at the same time, a stabilized output EC is supplied to load LC through the intermediary of a stabilized circuit 7. Also, the dummy resistors RA' and RB', which functions as discharge resistors used when the loads LA and LB are reduced and the output of the capacitor 4 is interrupted, are formed in such a manner that they will be connected in between the terminals of the non-stabilized outputs EA and EB and the terminal of the stabilized output EC. Accordingly, the dummy current on each circuit can be stabilized output EC. Accordingly, the dummy current on each circuit can be made equal and also the power consumption thereof can be reduced, thereby enabling to prevent the lowering of efficiency caused by the dummy resistors.

Title: Acceleration and deceleration detector
Inventor: HASHIMOTO NOBUYUKI
IPC: F02M25/06
Filed: 1980-12-10
Abstract: PURPOSE: To improve responce during acceleration by providing, to an acceleration and deceleration detector for purifying a vehicle exhaust gas, such a mechanism that the supply of air into an exhaust manifold is stopped during deceleration, but is promptly retrieved during acceleration.  
     CONSTITUTION: A valve element 54 is depressed by a spring 57 to close a port 56 so that air fed from a pump 5 to an exhaust manifold is shut-off during running at a constant speed, since the air port pressure of a carburettor is equal to an intake-manifold pressure and since chambers 47, 48 in a fluid-operating device 5 have an equal pressure. An acceleration sensing control valve 2 is actuated during gentle acceleration so that the atmospheric pressure from a port 20 is introduced into the chamber 48 of the operating device 4 to push up the valve element 54 and air from the pump 5 is fed into the exhaust manifold. A deceleration sensing control valve 3 is actuated during gentle deceleration so that ports 43, 42 are communicated together, while ports 23, 22 in the acceleration sensing control valve 2 are communicated together. Therefore, negative pressure in the air port of the carburettor is introduced into the chamber 48 of the operating device 5, and the valve element 54 is depressed by the spring 57, thereby air from the pump 5 is shut-off.

Abstract: PURPOSE:To improve entire transmission efficiency by executing communication with a data of less data quantity in data subjected to compression coding by taking a longitudinal direction of a document original in the main scanning direction and taking the lateral direction of the original into the main scanning direction. CONSTITUTION:In receiving a picture input instruction, an MPU 1 gives an input command to an input device 2 and stores picture raw data caused in this case to an input memory 3. Then the MPU 1 codes a raw data and stores a 1st coded data subjected to coding to a memory 6. In this case, a value of bit/inch in the main scanning direction is instructed to a corder 5. Further, the MPU 1 uses a horizontal/vertical conversion circuit 4 to apply horizontal/ vertical conversion to the raw data. Then the converted data are coded and a 2nd coded data are stored in the memory 6. When the quantity of the 1st coded data are less, the 1st coded data are dent. When the quantity of the 2nd coded data are less, the 2nd coded data are sent.

IPC: H01H19/00
Filed: 1987-07-10
Abstract: PURPOSE:To correctly generate pulses with the time interval corresponding to the arrangement by the number of lugs and prevent the occurrence of chattering by allowing the lugs of an operating body to push the coupling piece of a cam and rotate the cam to the switch operation position. CONSTITUTION:When an operating body 4 is rotated, a lug 22 provided on the operating body 4 pushes the coupling piece 19 of a cam 3, the cam 3 is rotated, and a bridging member 23 provided on the cam 3 bridges two contact plates 27, 28. The lug 22 of the operating body 4 is then released from the coupling piece 19, the cam 3 is rotated back, and the bridging member 23 is removed from two contact plates 27, 28. One pulse is obtained between two contact plates 27, 28 by this action. The pulse generation of a switch is thus controlled, on the other hand the cam 3 can be correctly operated with the optional pitch by the rotation of the operating body 4 provided separately. Pulses in response to the desire of a user can be thereby obtained, the operating feeling of the operating body 4 is smooth, and the chattering countermeasures of the contact plates can be reduced in half.

Title: Close coupling cable
Inventor: WATARI TATSU
IPC: H01B7/00
Filed: 1993-07-14
Abstract: PURPOSE:To suppress the transmission loss by adhesion of water or dust, and allow the close coupling transmission with an antenna in a stable level by making the part facing the antenna of the outer surface of an insulator into a flat form. CONSTITUTION:In a close coupling cable 1, the part facing an antenna 10, of the outer surface of an insulator 4, has a flat form in which this part is cut to form a flat surface 4a, and the remaining part is formed into a circular section. The space between the flat surface 4a and the antenna 10 is set to a distance G. Although the transmission loss of the flat surface 4a in which the distance between a conductor 2 and the insulator 4 outer surface is short is slightly increased by the adhesion of moisture or dust, the part of the insulator 4 outer circumferential surface in which the distance with the conductor 2 is long is lowered in field density which is easily influenced by moisture because this part is far from the conductor 2, even when the moisture or dust is adhered, and the transmission loss is difficult to increase. Otherwise, an outside insulator 15 is provided on the outside of the insulator 4, an opening part 15a is formed in the part facing the antenna 10 of the outside insulator 15. Thus, the transmission loss is difficult to increase.

Title: White balancing device and video camera
Inventor: SAITO KENJI
IPC: H04N9/73
Filed: 1991-07-16
Abstract: PURPOSE:To realize good photographing by lowering color failure, improving color reproducibility and preventing flicker. CONSTITUTION:A microcomputer 12 obtains brightness of an object and the state of split photometry based upon the opening degree of an iris 2, etc. A microcomputer 20 outputs white balance controlling signals RCONT and BCONT so that the values of color differencial signals R-Y and B-Y become equal to a reference value. A white balancing circuit 8 changes the amount of amplification of primary red color signal R and primary blue color signal B, corresponding to the values of the white balance controlling signals RCONT and BCONT. The values of white balance controlling signals RCONT and BCONT are changed when a brightness becomes higher than the previous one, or a split photometry mode changes. If these do not take place, they are fixed as they are. The values that the white balance controlling signals RCONT and BCONT can assume are limited to the values within a certain range, depending on outdoor mode or indoor mode. In addition, color reproducibility is improved by adjusting a gain and a hue at a matrix circuit 10. Further, a 1/100 electronical shutter is operated for preventing flicker in the area illuminated by a fluorescent lamp.
