    摘要: A disk drive housing structure has a rotating disk for recording information and a transducer adapted to write and read information on and from the disk. The structure further includes a positioning system having at least an arm to which the transducer is fixed and which is adapted to selectively position the transducer along the radial direction of the disk transducer by turning the arm. The structure also includes a member on which the disk, transducer and positioning system are mounted, wherein the mounting member includes a first housing which supports thereon both ends of a rotary shaft of the recording medium and both ends of a rotary shaft of the positioning system, and which has a first aperture part. The first housing further includes a second aperture part through which the disk and the rotary shaft supporting the disk are inserted and to which a supporting member for the rotary shaft of the recording medium is fixed.

    摘要: A ringing converter of the type having an output voltage stabilizing circuit connected on the primary side of a transformer. The converter is further provided with a circuit for detecting the primary current, which is proportional to the load current on the secondary side of the transformer. This enables detection of a change in the output voltage due to fluctuation in the load current on the secondary side, as detected by the detecting circuit. A signal indicative of the detected change is fed back to an oscillator circuit in order to stabilize the output voltage.

    摘要: A stabilizing power supply apparatus including, as a switching element, a magnetic amplifier supplied with a rectangular wave voltage produced by an inverter and controlled by a reset current. An error sensing circuit senses a difference between the output voltage of the magnetic amplifier and a reference voltage to produce an error signal corresponding to the sensed difference. An amplifier circuit amplifies the error signal into the reset current for the magnetic amplifier. The amplifier circuit includes a NPN-type transistor for amplifying the control current into the reset current and first and second diodes. The first diode has an anode terminal connected to a negative power supply line and a cathode terminal connected to the collector of the transistor in order that charge will not accumulate on the transistor base. The second diode has an anode terminal connected to the emitter of the transistor and a cathode terminal connected to the magnetic amplifier. The reset current is applied to the magnetic amplifier through the second diode to hold the output voltage of the apparatus constant by regulating the on/off timing of the magnetic amplifier in accordance with the difference between the magnitude of the output voltage and the magnitude of the reference voltage.

    摘要: In a power source device for a bubble memory unit consisting of a bubble memory part and a control part, a controlling supply voltage to be applied to both the bubble memory part and the control part is produced by a power source circuit based on a pulse width modulation system. The power source circuit is provided with a circuit which can expand the signal pulse width in excess of its upper-limit value during the ordinary voltage control. When the controlling supply voltage has become lower than a predetermined value, the pulse width is expanded so that the refresh operation may be perfectly executed when the power source device for the bubble memory unit is turned off.

    摘要: There is provided an illumination setting support apparatus that enables a user to easily set an optimal lighting pattern while visually checking. A schematic diagram of the illumination unit is displayed in the setting screen, so that clicking on a desired area inside this schematic diagram allows the arbitrary area to be selected from eight areas in the circumferential row of the “outermost circumference” of the external illumination unit. Lighting pattern information is transmitted to a bar code reader and is transferred to the external illumination unit. Imaging is performed while executing illumination control in accordance with the lighting pattern to thereby immediately display a live image on a PC.
