Filed: 1983-05-16
Abstract: PURPOSE:To reduce considerably the amount of a DC offset by driving all switching means by a two-phase clock, and grounding some of the means and the remaining means in opposite-phase relation. CONSTITUTION:A figure A shows an amplitude equalizer which uses a switched capacitor which has a small DC offset. In the figure, C1 and C2 are integral capacitors. A figure B shows an RC equivalent circuit. The transfer function T2 (Z<-1>) of the area Z of the circuit in the figure A is expressed by an equality I . In the figure B, when E<1>in and E<2>in are feeding voltages for the amount of the DC offset, and R<1>in and R<2>in are driving resistances for the amount of the DC offset, the amount Vout0 of the DC offset at the output terminal of the circuit is expressed by an equation II. Therefore, when the amount of the DC offset is reduced, the R1 is decreased in the figure B, and K4 should be large in the figure A. This invention realizes a circuit which has larger K4 than before.

Abstract: PROBLEM TO BE SOLVED: To prevent the flow out of the hot melt group adhesive agent to an end of the trim, and to effectively utilize the material, and to quickly perform the pad positioning work without hindering the appearance of a product by forming a back surface of an interior part with a plate-like rib at positions, in which an impact absorbing pad is to be provided. SOLUTION: An impact absorbing pad 40 is adhered for fixation to a back surface of a lower member 30 corresponding to a waist part of an occupant, and in the case where an impact is applied from outside, the impact absorbing pad 40 is broken by the external force through a side wall panel so as to absorb the impact. Bosses 33 are formed in an area (a), in which a pad is provided, at two positions, and plate-like ribs 34 are formed for standing in a waist part at two positions. Furthermore, the area (a) provided with pad is coated with the hot melt group 60, and even in the case where the adhesive agent 60 to be filled in a peripheral part of the boss 33 is going to be flowed outside the impact absorbing pad 40, the plate-like rib 34 prevents the flow-out with the weir work thereof.  With this tractor, generation of malfunction that the adhesive agent is flowed out to an end of product and that the appearance of the product is hindered is prevented.

Abstract: PURPOSE:To increase the average doping rate, increase the energy density of a cell, and improve the cycle life by increasing the doping rate to a high molecular compound having the conjugated double bond as a principal chain of a positive electrode and decreasing the doping rate to a negative electrode. CONSTITUTION:The quantity of a dopant doped to a conjugated high molecular compound, e.g., acetylene high polymer, polyparaphenylene, poly(2,5-thienylene), polypyrrole, is 2-40mol% per mol of a repetition unit of the conjugated high molecular compound for a positive electrode, and 2-40mo% per mol of a repetition unit of the conjugated high molecular compound for a negative electrode.

Title: Load control circuit device
Inventor: UEDA SHINICHI
IPC: H03K17/725
Filed: 1985-04-18
Abstract: PURPOSE:To compensate the drop of the DC voltage due to a short circuit by actuating an oscillation circuit in response to the control input, turning on and off a switching element by the oscillation output of the oscillation circuit and giving the short/open circuit to the secondary coil of a tripod transformer for control of the load. CONSTITUTION:An oscillation circuit 14 starts its oscillations in response to control inputs 11, 12 and 13, and a switching element TR is turned on and off intermittently by the oscillation output. Then a secondary coil 3 undergoes the intermittent short/open circuits, and a current control element 7 is turned on in response to the short circuit. Then the load 6 is driven. while the adverse electromotive force produced by the ON/OFF operations of the element TR is superposed on the AC signal when the coil 3 is short-circuited and rectified by a rectifying circuit 9. This rectified force is supplied to a power supply circuit 10. Thus the DC voltage having a small drop degree is obtained and therefore the drop can be compensated when the coil 3 of a tripod transformer 1 is short-circuited.

Filed: 1980-06-23
Abstract: PURPOSE: To prevent a fluctuation of the tape transport extent caused by a change of speed of slow motion reproduction, by controlling the level or width of the intermittent transport driving pulse in accordance with the intermittent period of a tape.  
     CONSTITUTION: The slow motion reproducing speed with which the intermittent normal transport due to a capstan equivalent to a pitch of the control signal corresponding to a frame of pause of a magnetic tape within a prescribed frame period number is repeated varies in accordance with the number of selection frame periods in a stop mode. In case the speed of reproduction is varied, a slow-speed monostable multivibrator 6 is controlled via a transistor 20, a capacitor 18 and others with control of a variable resistance 21 of a correcting circuit 17. Then the width and others are controlled for the driving pulse delivered from a forward-turn monostable multivibrator 7, and thus a correction is given to the fluctuation of the starting state due to the residuel energy according to the slow reproduction speed of the intermittent drive of a capstan produced by a step motor 1 or the like. In the same way, a fluctuation can be prevented for the tape intermittent transport extent caused by a change of speed of slow motion reproduction also at the brake side.

Title: Prepreg, its production and production of multilayer printed wiring board with the prepreg
Inventor: MIZUNO YUTAKA
IPC: H05K3/02
Filed: 1995-04-11
Abstract: PURPOSE: To obtain a prepreg reduced in the flow-out of a resin from a substrate, and useful for multi-layer printed wiring boards free from the generation of burr with the flowed resin, troubles on bending, the shortage of the interlaminar thickness, the failure of charging, etc., by enhancing the hardness of the surface layer(s) on one side or both the sides of the prepreg on comparison with those of other parts. CONSTITUTION: The surface of a prepreg is subjected e.g. to a heating treatment with far IR light to enhance the hardness of the surface layer or surface layers on the surface or both the surfaces of the prepreg in comparison with those of other parts. For example, the resin in the surface layer or surface layers on one side or both the side and the resin in other parts have a gel time difference of 3-80%. The prepreg is obtained by raising the temperature of the surface layer in a short time to enhance the hardness of the surface layer, and subsequently cooling the heated surface layer, before the temperatures of inner parts follow the temperature of the surface layer. Thus, only the surface layer is heated so as not to transmit the heat to the inner parts.

Filed: 1995-04-11
Abstract: PURPOSE: To reduce the loss rate of refractories and to improve the preheating effect by blowing mixed gas of inert gas and oxygen into a furnace and diluting and cooling the high temp. exhaust gas in the furnace produced by secondary combution to a specific temp. or blow. CONSTITUTION: The inert gas (N2 or CO2 ) or the air is blown into the furnace from a dilute gas blowing nozzle 5 provided on the furnace wall of the melting furnace 1 at such angle as not to collide directly against molten metal 3. A top-blowing oxygen lance 4 is inserted from the furnace top hole. The temp. of the dilute gas may be the room temp. and gas flow rate is necessary to secure the quantity that the temp. of the exhaust gas is suppressed to at least <=1700 deg.C. This dilute gas quantity can be decided by (the exhaust gas quantity) ×(exhaust gas temp. -1700 deg.C)/(exhaust gas temp.) The lower limit of the exhaust gas temp. is suitably at about 1500 deg.C. By this method, the inexpensive inert gas or the air can be used as the dilute gas and the large economical merit can be obtd.
