  • Publication number: 20010013782
    Abstract: An electrical connection testing device is provided with a connector holder (12), first and second probe holders (13, 14) which are successively arranged such that the connector holder (12) and the second probe holder are movable toward and away from the connector holder (12). A pushing mechanism (18) for pushing a receiving surface (14d) of the second probe holder (14) at the opposite side from the connector holder (12) is so coupled with the second probe holder (14) as to be movable toward and away from the second probe holder (14). The second probe holder (14) and the connector holder (12) are moved according to the movement of the pushing mechanism (18), thereby being positioned at testing positions (P1) where probes (16, 17) are inserted into testing holes (1a) of a connector (C) from opposite sides or at retracted positions (P2) where the connector can be taken out of a connector holder (12).

  • Publication number: 20010004112
    Abstract: There is disclosed a semiconductor light emitting element formed by selective growth and being high in light emitting efficiency, in which at least one GaN-based layer grown by ELO is stacked/formed on a sapphire substrate, and a fluorescent substance for converting an ultraviolet light to a visible light is contained in a selective growth mask material layer for use in this case. Since this fluorescent substance converts the ultraviolet light to the visible light, a binding efficiency of the ultraviolet light to the fluorescent substance is enhanced in either one of a center light emitting type and UV light emitting type of light emitting elements. By further containing the fluorescent substance into a passivation film, the efficiency is further enhanced.

    Abstract: A nitride compound semiconductor light emitting element comprises a substrate, a nitride compound semiconductor n-type layer, a mask layer having a predetermined opening, a nitride compound semiconductor buffer layer epitaxially grown on said n-type layer exclusively at said opening. The buffer layer has a recess on its top face so that a thickness of said buffer layer is thinner above a central portion of the opening and thicker above edge portions of the opening. A nitride compound semiconductor active layer is selectively formed on the recess of the buffer layer to be thicker at the central portion of the recess and thinner at the edges of the recess. A nitride compound semiconductor burying layer overlays the mask layer and the active layer to cover the active layer.

  • Patent number: 5270992
    Abstract: An apparatus for controlling rotation of a spindle motor includes a lock detection unit, a memory unit, a comparison unit, and a control unit. When the lock detection unit detects the lock state of the time base servo loop, a voltage corresponding to the frequency of a read RF signal is stored in the memory unit. When the control unit detects that the rotation velocity of the spindle motor greatly deviates from a normal rotation velocity, it effects a control so as to accelerate or decelerate the spindle motor in dependency upon a compared result of the comparison unit which makes a comparison between a voltage corresponding to the frequency of the read RF signal and a voltage stored in the memory unit.

  • Patent number: 5210725
    Abstract: A control circuit of a tray loading apparatus determines, according to a disc size and a tray moving direction, a time during which to control the motor at a constant speed. When the specified time has elapsed after the motor was started, the control circuit produces a pulse-width modulated output to slowly lower the motor speed, eliminating impact noise when the tray strikes a stopper. This motor deceleration time is measured. When the measured deceleration time disagrees with a preset or previously detected target deceleration time, the difference is either added to or subtracted from a constant-speed motor operation time and the resultant value is taken as the next target time for constant-speed motor operation. In this way, by changing the time during which the motor is driven at a constant speed, any variations in the tray moving speed as might occur from varying loads on the motor are absorbed to keep the motor deceleration time and decelerating speed unchanged, thus making the tray motion smooth.

  • Patent number: 4703241
    Abstract: A motor servo system is disclosed which is capable of accomplishing the precise control of a set point of a mechanical element to be controlled without particularly considering the mechanical connecting condition between a motor and the mechanical element and being readily accommodated to a variation of the set point and a variation of overshoot due to a variation of load. The motor servo system is constructed in a manner such that a controlled set point of a controlled element such as a mechanical element is independently set by means of a time signal generating section preceding a servo circuit section.
