Title: Voltage comparator
Inventor: FUJITA TSUNEO
IPC: H03M1/34
Filed: 1984-12-25
Abstract: PURPOSE:To realize completely a low electric power consumption by inhibiting the short-circuit of an input terminal and the output terminal of an inverting circuit, when a comparing operation is stopped, also connecting the input terminal to a prescribed potential, permitting said short-circuit, when said operation is executed, and also detaching the input terminal from the prescribed potential. CONSTITUTION:When a control signal 330 is set to '1', the comparing operation is executed in accordance with a two-phase clock phi and -phi. Also, in a period T1, the input/output terminals of the inverting circuit 310 are short-circuited by the operation of switches 301-305, a bias current flows to the circuit 310 so that the input/output terminals become the same potential, and the input/output terminals are biased to the same potential. Next, when the control signal 330 is set to '0', the comparator becomes a low power consumption state, and even if the switch 303 is turned on and off by a fact that the switch 305 is always off, the input/output terminals of the circuit 310 are hardly short-circuited, and no bias current flows to the circuit 310. Also, since the control signal becomes '1' and a switch 306 is always turned on, the input terminal of the circuit 310 is fixed to a potential VC. Accordingly, even if an analog input voltage VS is impressed to a capacity 320, the variation of the voltage VS exerts no influence on the circuit 310.

Abstract: PURPOSE:To improve voltage regulation by providing secondary windings which are magnetically coupled with a plurality of split primary windings, providing resonance capacitors to be added, and mutually shifting resonance frequencies with each primary winding and the resonance capacitor. CONSTITUTION:A flyback transformer 10 has split windings PC1 and PC2. Film winding bodies 12 as resonance capacitors Cp1 and Cp2 are added to the primary windings. Secondary windings SC1-SC4 are sequentially laminated and arranged thereon. For example, when the attaching positions of terminals 24a1 and 24b1 are changed in the film winding body 12a, the magnitude of the inductance of the primary winding PC1 is adjusted. An insulating film 16 is provided between conductor foils 18 and 20, and a capacitance CP1 is formed. Said capacitor can be appropriately adjusted by the facing areas of the conductor foils 18 and 20 and the dielectric constant of the insulating sheet 16. The resonance frequencies of the primary windings PC1 and PC2 can be shifted mutually by the combinations of said values. In this way, a peak current Ip flowing through the secondary winding becomes small, and voltage regulation is improved.

Title: Ink cartridge
Inventor: MATSUI SHINYA
IPC: B41J2/175
Filed: 1988-11-02
Abstract: PURPOSE:To make the subject device compact and increase the efficiency of ink discharge recovery action by providing an ink pressurizing device in an ink flow path between an ink storage section and the joint section of an ink cartridge and a device for blocking an ink flow in the ink flow path between the pressurizing device and the ink storage section. CONSTITUTION:A pressing member 106 is pressed against an ink flow path blocking section 112 in pressure recovery mode, and the ink flow path blocking section 112 is blocked. In this way, the flow of ink between an ink storage section 116 and a joint section 113 is shut off. Next, a pressing member 15 is pressed against the head of an ink pressurizing section 111. If the pressurizing action is completed, the pressing member 106 moves backward and the ink flow path blocking section 112 becomes open. In this case, a negative pressure generated when the compressed air is released from the ink pressurizing section 111, is transmitted to the ink storage section 116, so that the negative pressure is not applied to an ink cartridge head. If the pressing member 105 moves backward, the ink pressurizing section 111 is restored to its original state resulting in the re-currence of a state before the recovery of pressure.

Filed: 1991-09-30
Abstract: PURPOSE:To shorten the processing time of Fourrier transformation in a multidimensional space, and to attain a high speed operation by simultaneously performing in parallel the Fourier transformation for coordinate axes at each point on a plane perpendicular to an aribitrary coordinate axis direction along which the Fourier transformation is to be executed. CONSTITUTION:At the time of Fourier transforming values expressed on, for example, 128X128X128 lattice points in a three-dimensional space into the same number of points in the inverse lattice space, the Fourier transformation is divided into the operation in each coordinate axis direction, and expressed by the superposition of the Fourier transformations in the various coordinate axes. Then, the fast Fourier transformation using the battery arithmetic operation is executed in parallel for the entire values in the (y) and (z) axis directions in the plane perpendicular to the (x) axis. At the time 128X128=16384 points are present in the yz-plane, and the Fourier transformation in the (x)-axis direction can be processed to those entire pointed in parallel. Therefore, the processing speed of the Fourier can be performed at several tens of timed faster speed than by using, for example, a parallel computer having registers for processing 100 pieces of vectors.

Filed: 1986-11-25
Abstract: PURPOSE:To facilitate IC-implementation and to utilize a switch for diverse purposes by composing the switch circuit of an input resistance and an MOS transistor(TR) with gate-source capacity, and supplying a control signal through the input resistance. CONSTITUTION:Switch circuits 11-13 consist of MOS-FETs Q11-Q13 and input resistances R11-R13, and gate-source capacity Cgs is formed between a gate and a source as control terminals. when a power switch S1 is turned on and electric power Vcc is applied to a power line 11, a control voltage Vc is supplied as the control signal to the respective switch circuits 11-13 through the line 11. The time constant determined by the input resistance R11 and gate- source capacity Cgs of the switch circuit 11 is minimum, so the control voltage Vc is applied to the gate of the TR Q11. The switch circuits 12 and 13 are both off in this period and neither of amplifiers 2 and 3 operate. An amplifier 1, therefore, operates a specific time after the power switch S1 is turned on, but the amplifiers 2 and 3 are not in operation and a rush current is extremely small.

Title: Impact relaxation device of tunnel entrance
Inventor: OKADA TAKANORI
IPC: E21D9/14
Filed: 1994-11-15
Abstract: PURPOSE: To relax sufficiently an impact generated when a train enters in a tunnel, by installing a reserve tunnel at the entrance of the tunnel, and forming the reserve tunnel to widen the section area gradually as going from the connection at the inner side of the tunnel to the opening end. CONSTITUTION: At the opening end 6 side of the entrance part of a reserve tunnel 4, the section area of the reserve tunnel is made the maximum, and the majority of the air operating to a train when the train enters to the entrance at a high speed is exhausted to the outer side through a space around the train. As a result, an impact pressure applying to the train can be prevented. And the section area of the reserve tunnel 4 is made the smaller gradually as going to the inner side of the tunnel 4, and finally the section area is made equal to that of the main body part 3.  Consequently, during the time when the train advances to the inner side of the entrance part, and is going to enter to the main body part 3, the pressure operating to the train is raised gradually up to the level corresponding to the pressure in the main body part 3, so as to prevent the generation of a large impact when the train enters to the tunnel 3.
