Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability on connection by disposing insulation materials for interlayer reinforcement against compressive force in the direction of thickness at a large number of points in an insulating layer. SOLUTION: A large number of insulating bumps (insulating materials for interlayer reinforcement) 22a are arranged on the surface of conductive foil, represented by a copper foil 16a, in specified positions, and a large number, of conductive bumps (conductive materials for interlayer connection) 14a are arranged on the surface of conductive foil, represented by copper foil 17a, in specified positions. Both arrangements of bumps are superposed on each other with the bump formed sides facing each other and an insulating sheet 13a in-between, and the laminate of the three is subjected to heat press. Then the sheets 16a, 17a of copper foil are bonded to the upper and lower faces of the insulating sheet 13a by fusing, and simultaneously the conductive bumps 14a and the insulating bumps 22a penetrate the softened insulating sheet 13a and are press-bonded to the copper foil 16a.  As a result a multilayer structure wherein the copper foil 16a and the copper foil 17a are connected with each other through the conductive bumps 14a, is obtained. Thereby highly reliable interlayer connection is ensured.

Title: Activating method for zirconia oxygen sensor
Inventor: KAWAI TAKASHI
IPC: G01N27/41
Filed: 1993-12-29
Abstract: PURPOSE:To activate a sensor element without bringing about the structural change to zirconia by alternately impressing between electrodes a processing voltage whereby the partial pressure of oxygen at an interface between an electrode and a solid electrolyte of the sensor element becomes not smaller than a limit value causing blackening. CONSTITUTION:When sensor cells 3, 5 are driven for a long time, oxygen is adsorbed to the electrodes 11, 14, which raises the internal resistance. Therefore, each sensor cell 3, 5 is activated during control or before and after control of the air fuel ratio. At this time, if an alternating voltage to be applied is too large, zirconia constituting the sensor cells 3, 5 blackens, with deteriorating the solid electrolyte. The deterioration can be prevented by controlling a processing voltage so that the partial pressure of oxygen at a three-phase interface of the electrodes 11, 14 which are cathodes when the voltage is applied is not smaller than a safe limit thereof, i.e., 10<-34>atm not causing blackening at 500-800 deg.C.

Title: Drum type washing machine
Inventor: KAWAGUCHI TOMOYA
IPC: D06F33/02
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To precisely detect a load quantity whichever wash in a dry or wet state is housed in a drum. SOLUTION: In a state where a balancer is at a drum highest position, the drum is stopped (S1) and rotated fast (S2) to detect an eccentricity quantity W due to the uneven distribution of wash (S6). As the eccentricity quantity W is large when the wash is in a wet state, whether the wash is dry or wet is discriminated by the quantity W. In addition, when the eccentric position is in the neighborhood of the opposed position of the ballancer, water is poured to the ballancer to ballance the drum (S9 to S11) and to start to a fast dehydrating rotation (S12, S13), and then, energizing to a motor is disconnected (S14). The heavier the drum is because of a larger load quantity, the longer time (t) the drum requires to decelerate from 900 rpm to 200 rpm is. Then, the load quantity is judged based on the quantity W and the time (t) (S19).  Thereby, a precise load quantity is obtained whichever the wash is dry or wet.

Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To perform high-speed power control for responding to drastic signal change by generating and setting a binary value power control bit opposite to the binary value of a power control bit immediately before in response to the fact that a signal sound quality parameter does not exceed (fall below) an upper (lower) limit value for an upper (lower) limit value margin. SOLUTION: A controller measures reception SNR and compares it with Sh+Ss+Sm. In the case of being larger, a parameter Sm is increased by an amount Ss and the parameter Sn is set to zero. On the other hand, in the case of being not larger and being smaller than Sb-Ss+Sn, the parameter Sm is set to zero and the parameter Sn is reduced by the amount Ss. Also, in the case of being neither larger or smaller, it is judged that an FPC to be transmitted is required to be provided with the value F=1 when the FPC bit immediately before is zero and to be provided with F=0 when it is not zero. Also, margin parameters applied to limit value comparison including the upper and lower limit values are denoted by Sm and Sn, a power step size for changing transmission signal power is denoted by Ss and the lower limit value of the reception SNR is denoted by Sb.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide the method and the device for speech reproducing in which no change is made for an interval even though the reproducing speed is vaired. SOLUTION: In the voice reproducing method, in which original speech signals 'a' recorded on a recording medium are reproduced, the signals 'a' are passed through a low pass filter and fundamental speech signals 'd' (consists of a fundamental period Tp) are extracted. Then, rising zero cross points D of the signals 'd' are detected. After the detection of the points D, the signals 'a' are segmented into subframes C (C1 , C2 , C3 , C4 , C5 and C6 ) at the positions corresponding to the points D on a time axis. If a reproducing speed is to be increased, a portion of the subframes C is deleted. If the speed is to be decreased, repetition is made for once or twice to generate reproduced speech signals 'e' and the signals 'e' are continuously reproduced.
