Filed: 1992-12-04
Abstract: PURPOSE:To provide a method of manufacturing an electronic component mounting board, wherein a power supply line and a GND line can be reduced in inductance, and the board can be enhanced in degree of freedom of design and lessened in cost dispensing with a press process. CONSTITUTION:A power supply layer 3 and a power supply lead 7 are electrically connected together through the intermediary of a lead connector 3a provided to the periphery of a printed wiring board P, and a GND layer 4 and a GND lead 8 are also electrically connected together through the intermediary of a lead connecting pad 4b provided to the periphery of a printed wiring board P. Therefore, a power supply lead 7 and a grounding lead 8 large in inductance are lessened in length, so that a power supply line and a GND line are reduced in inductance. The power supply layer 3 and the GND layer 4 are formed on the printed wiring board P, so that they can be enhanced in degree of freedom of design when they are formed. As printed wiring boards P each provided with the power supply layer 3 and the GND layer 4 are manufactured through a multiple unit forming method, the board P can be lessened in cost dispensing with a press process.

Abstract: PURPOSE:To improve the bond strength by applying a pressing force produced by a weight from an adherend to at least one of a material to be bonded and applying an alternating load thereto while heating in that state. CONSTITUTION:An adherend 1a and a material 1b to be bonded are accommodated in a process tube 5. A rod 2 is set to at least one of them and a weight 6 is set to the other. A prescribed pressing force is applied through the weight 6 or the rod 2 to each of the adherend la and the material 16 to be bonded. In that state, both the adherend 1a and the material 1b to be bonded are then heated by a heater unit 4. A pressing unit 3, etc., such as an actuator is set to the other end of the rod 2 and an alternating load is applied thereby. That is to say, an alternating load is applied under a suitable temperature condition so as to obtain a prescribed bond strength value. In addition, the gas generated in this process is removed through cooling fluid supply and discharge openings 7 and 8. It is proved by experimental results that the residual stress is reduced by repeatedly applying a load as a bonding pressure between the materials and that the wettability, the chemical reactivity and the bond strength of the bonded interface are improved thereby.

Filed: 1991-11-15
Abstract: PURPOSE:To enable formation of a noise eliminating zone constantly in the vicinity of ears a human even with his head moving, when noise elimination is desired in the vicinity of his ears. CONSTITUTION:A noise elimination operation is started after the filter coefficients w(1) through w(m) for the respective predetermined proposed control pints P1 through Pm are memorized by a coefficient memory part 6. When control point to be noise-eliminated moves e.g. from the position of the proposed control point P1 to the position of the proposed control point P2, a control point selective part 7 selects the proposed control point P2, and transmits the information to a signal processing switching part 8. The signal processing switching part 8 reads the filter coefficient w(2) corresponding to the proposed control point P2 from the coefficient memory part 6, and set the value as the filter coefficient of a signal processing part 2 and switches the signal processing. This arrangement allows the movement of the noise-controlled point from P1 to P2 to be followed and rapid noise elimination to be realized in the vicinity of the position P2.
