Title: Triangular wave signal generating circuit
Inventor: KAWASAKI MOTOAKI
IPC: H03K7/08
Filed: 1992-10-13
Abstract: PURPOSE:To generate a prescribed triangular wave signal by controlling the current value of charging current source by an outputted error signal and at the same time controlling the duty of an input clock signal. CONSTITUTION:A clock signal is inputted to a triangular wave signal generating part 6, and at the same time the value of the charging and discharging currents flowing to a capacitor C1 are equal to each other. Then the charging and discharging modes are switched by a Q8 and a triangular wave signal is generated. The triangular wave signal is inputted to the comparators 8 and 11 respectively via a buffer 7. Then the output of a charge pump circuit 12 generates a peak error signal by a peak error generating circuit 13 and controls the charging/ discharging value of the part 6. Meanwhile the input of a charge pump circuit 9 generates an offset error signal by an offset error generating circuit 10 and inputs this error signal to a variable pulse delay circuit 3 to vary the pulse delay time. Thus the clock duty is controlled.

Title: Simulation method for movement of humand body and animation generating method using the same method
Inventor: SHINAGAWA YOSHIHISA
IPC: G06F19/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To establish technology which can simulate or animate a human body without using any expensive device by estimating the movement of the human body based on the dynamics according to optimum control theory which adopts a minimum muscle movement function as a target function. SOLUTION: According to the optimum control theory which adopts the minimum muscle movement function as the target function, feedforward control is performed first to calculate the movement of the human body (S1). Then the posture of the human body on a calculated track is inspected (S2). Here, when there is a problem as to the posture, the movement of the human body is corrected (S3). The posture is inspected and corrected on two levels. Namely, border postures (starting and ending postures of movement) and then halfway postures are inspected and corrected. Thus, desired movement data are completed and then animated and the data are displayed on a display and stored in a storage device (S4). The animation is carried out by interpolation between key postures that the user specifies.

Abstract: PURPOSE:To prevent the sticking of a splash to a mold by coating vacuum grease to the wall surface of a crucible and executing a vacuum arc welding method (VAR). CONSTITUTION:The vacuum grease is coated to the wall surface of the crucible 1 to be used in the VAR which yields a steel or alloy by the melting and solidification of a material to be melted (consumable electrode) 2 in a vacuum. As a result, a film is formed by the combustion of the vacuum grease and the sticking of the splash 16 to the molded product is prevented. The vacuum grease is required to be coated to the upper part of the molten metal 17 surface of the crucible 1 as the splash 16 sticks more to the upper part of the surface 17 while the splash 16 melts again the lower part of the surface 17. The sticking of the splash 16 to the mold is prevented according to the above-mentioned method and therefore the steel ingot has a good surface and the VAR mold having extremely good quality is obtd. without the intrusion of foreign matter into the molten steel and without flawing of the mold.

IPC: G01L5/00
Filed: 1985-12-09
Abstract: PURPOSE:To prevent the titled sensor from a almost receiving the effect of the resistance of the peripheral pat of a lattice point, by a method wherein the contact areas of the upper and lower electrodes and a pressure-sensitive conductive rubber sheet at the lattice points of the upper and lower electrodes are widened and the widened parts are connected by fine conductor parts. CONSTITUTION:The upper and lower electrodes 21, 22 formed to upper and lower substrates 31, 32 are contacted with a pressure-sensitive conductive rubber sheet 1 at the lattice points of the upper and lower electrodes crossing at right angles in a continuity state and the contact areas thereof with said sheet 1 are enlarged to respectively form widened parts 2a at the lattice points of the upper and lower electrodes 21, 22. The widened parts 2a in one electrode are connected by fine conductor parts 2a in each of both upper and lower substrates 31, 32 and conductors are led out to an external circuit from the upper and lower electrodes 21, 22. Therefore, the change in the resistance of the pressure-sensitive conductive rubber sheet 1 due to pressure can be sufficiently detected as the change in the resistance only of each lattice point part and the effect of connection conductors 2b can be reduced to effect equal to or less than a conductor width ratio. As a result, pressure acting on the lattice point or switch operation can be accurately detected on the basis of the change in the resistance between the upper and lower electrodes.

Filed: 1989-10-23
Abstract: PURPOSE:To improve the compensation performance of an apparatus in such manner that a three-phase PWM converter generates only a harmonic voltage and an exciting current necessary for maintaining a parallel resonance is caused to flow from the three-phase PWM converter. CONSTITUTION:A first reactor 32 and a resonance circuit 3 composed of a capacitor 31 and parallel-resonating with a power supply frequency are connected in series with each phase of a three-phase AC power supply 1 for supplying a load 2 such as thyristorized Leonard apparatus with power, an AC reactor 4 is connected in series with each phase of the side opposite to the power supply side of the resonance circuit 3, and a three-phase PWM converter 5 is connected with the side opposite to the resonance circuit 3 side of this AC reactor 4. Further, this PWM converter 5 generates only a harmonic voltage. Therefore, a harmonic current canceling the harmonic current of the load 2 and the basic exciting current circulating through the parallel resonance circuit 3 and power supply 1 flows to the PWM converter 5. As a result, it is possible to cause an exciting current necessary for maintaining a parallel resonance to flow when the PWM converter 5 is used as a harmonic voltage source.
