Title: Filter for active noise control system
Inventor: FUJISAWA KAZUYA
IPC: H03H17/00
Filed: 1992-10-16
Abstract: PURPOSE:To reduce noise with characteristics coincident with human senses by making the evaluation function of an adaptive filter, which is applied for an active noise control system, dependent on a frequency. CONSTITUTION:A reference signal x(n) is inputted to an adaptive filter 1, and an output signal y(n) is outputted to a noise observation point P as a second- order sound source. A noise signal d(n) and the output signal y(n) of an inverse phase are added to the noise observation point P, and the noise level is reduced. In this case, an error signal epsilon(n) between the noise signal d(n) and the output signal y(n) changed momentarily is inputted to a frequency dependence filter 3 provided with A characteristics. The frequency dependence filter 3 is composed of an FIR filter, and a filter coefficient fk is previously set so as to provide the A characteristics used for measuring noise, for example. Therefore, the error signal epsilon(n) is turned to a corrected error signal delta(n) expressed by a formula shown in the figure, outputted and inputted to a filter coefficient calculating means 2. At this means 2, a filter coefficient hk of the adaptive filter 1 is calculated so as to minimize the square root sum of the error signal delta(n).

Title: Dc-dc converter
Inventor: SASAKI FUMIHIRO
IPC: H02M3/155
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To stabilize a step-up circuit. SOLUTION: A transistor 48 is turned ON, OFF to generate a counterelectromotive force in a coil 42, and a high voltage is charged in a capacitor 46 through a Zener diode 44. Since a yield current of the diode 44 flows to an earth through the transistor 48, a voltage applied to the transistor 48 becomes a predetermined value or less. Since the yield current of the diode 44 does not flow directly to the earth, a change in the step-up voltage can be prevented.

IPC: B32B5/32
Filed: 1993-10-12
Abstract: PURPOSE:To manufacture a cushion pad which gives a feeling of comfortable touch at low cost by injecting a material HR urethane stock solution into the bottom force of a die, then blocking the bottom force with an intermediate force for supporting a support plate, and blocking the intermediate force with a top force after injecting a second material urethane stock solution into the intermediate force with the subsequent operation to vent a gas and at the same time, form and part the upper and lower layers of a pad. CONSTITUTION:A material HR urethane stock solution 11 is injected into the recessed part 12 of the bottom force 7 of a die, and the bottom force 7 is blocked by an intermediate force 10 for holding a supporting plate 4 for supporting a finished product. Then after the molding, a second material urethane stock solution 14 is injected into the recessed part 15 of a top force 16 and the intermediate force 10 is blocked by the top force 16 to seal the stock solution 14. Further, the stock solutions 11, 14 are molded into a foam as an upper cushion pad layer 3 and a lower cushion pad layer 5. In addition, a groove is formed between the upper and lower molding parts 10a, 10b of the intermediate force 10 during the molding process and a gas is vented. A through hole is previously opened in the supporting plate 4, thus allowing both upper and lower layers 3, 5 to communicate with each other so that the support plate 4 is prevented from being separated. Thus it is possible to vent a gas from the HR urethane easily and manufacture an urethane pad with high dimensional accuracy at low cost by parting the molding from the die after molding the upper and the lower layer 3, 5.
