摘要:
A printed board (5) for mounting electronic component, a method for making the same, and an arrangement for connecting a conductive elements (8, 8′) to the printed board are provided. The printed board includes an insulating substrate (50), and at least one metal terminal (53, 54). The substrate is formed with at least one opening (51, 52) penetrating the substrate. The metal terminal is fixed to the substrate so as to bridge the opening, without projecting out of the substrate.

For example, in a conventional high frequency switch used for a mobile phone and so on, high frequency distortion is caused by a diode which is turned off upon transmission. A high frequency switch includes a switch circuit for switching transmission and reception performed via a transmitting terminal and receiving terminals, said switch circuit having a diode turned off upon transmission, and a low-pass filter for suppressing high frequency distortion caused by the diode upon transmission.

There is provided an integrated electric compressor that is improved in reliability. Bus bar connection is employed for electrical connection between a power board 16 and the power source side and between the power board 16 and the motor side, and welding is employed for joining a bus bar to a capacitor 13 and a reactor 14, for joining board-side terminal parts of the bus bar to PN terminals 20a and 20b, and for joining UVW terminals 25a, 25b and 25c to housing-side terminals 28a, 28b and 28c. By employing resistance welding for the welding, the terminals can be joined to each other with stabilized quality. Further, since flat joint plates are provided on one end side of the housing-side terminals 28a, 28b and 28c, and the UVW terminals 25a, 25b and 25c are welded thereto, reliable joints between terminals can also be attained in these portions.

To provide a process for producing inorganic spheres having a substantially uniform particle size with high productivity. In a process for producing inorganic spheres, which comprises a step of injecting an alkaline aqueous liquid containing an inorganic compound into a laminar flow of an organic liquid containing a surfactant through micropores to form a W/O type emulsion, and a step of solidifying droplets of the aqueous liquid containing an inorganic compound in the W/O type emulsion by an acid to form inorganic spheres, as the organic liquid, one which is brought into contact with an acid in a state of the W/O type emulsion or after separated from the W/O type emulsion, or one which is brought into contact with the aqueous liquid and then separated and recovered, is used.

A vehicle speed determining device determines a running speed of a vehicle, on the basis of pulses received from a vehicle speed sensor. A first determination that the running speed of the vehicle has been zeroed is made, if a next pulse has not been received from the sensor, within a predetermined first length of time after the reception of a last pulse from the sensor. A second determination that a period of the next pulse to be received next is abnormally long is made, if said next pulse has not been received within a predetermined second length of time after the reception of the last pulse. If the second determination is made, the first determination is inhibited until the next pulse has been received.

A shift control apparatus for an automatic transmission of a motor vehicle is disclosed. The shift control apparatus includes a shift control device for automatically shifting the transmission according to a predetermined shift control pattern, on the basis of a speed of the engine and a currently required output of the engine. When a vehicle driver operates to re-accelerate the vehicle after deceleration with the transmission shifted down to the low-speed gear position, the transmission is shifted up from the lower-speed gear position to the high-speed gear position having the smaller speed reduction ratio than the lower-speed gear position, if a predetermined period of time has not elapsed after the low-speed gear position is established. Also disclosed is a shift control apparatus including the same shift control device, wherein the engine idling speed is raised from a normal level up to an elevated level when an additional load is applied to the engine, and wherein a shift-down point of the engine speed in the shift control pattern is shifted, in response to a rise in the idling speed to the elevated level, from a first point corresponding the normal level of the idling speed up to a second point corresponding to the elevated level.

In an electric power steering control system, a phase compensator of the steering torque is made of an analog circuit and an anti-phase compensator is made by the software of a microcomputer, thereby to eliminate the changes in the gain and the phase by the phase compensator of the analog circuit near the oscillation frequency, so that the steering torque signal equivalent to that of no phase compensation necessary for the computation at the observer is computed from the phase-compensated steering torque signal.
