  • Patent number: 4487224
    Abstract: An air switch comprises a switch body having a recess thereon and a switching member having an output connection port. The recess is connected to vacuum and pressure outlets through passages in the switch body. The vacuum passage is connected to a port on the wall of the recess while the pressure passage is connected to a partially circularly extending channel on the recess wall. The switching member is rotatably received in the recess and includes a radially extending channel on its inner wall. Positioning of the switching member in the vacuum or pressure modes places the member channel in fluid communication with either the vacuum port or the channel on the recess wall. When in the vacuum mode, the pressure channel is vented to the atmosphere and when in the pressure mode, the vacuum is similarly vented. When in the minimum pressure mode, a portion of the pressure is vented to the atmosphere although this pressure venting is reduced to zero when the switching member is in the maximum pressure mode.

  • Patent number: 4488184
    Abstract: A videodisc playback system is equipped with a reading device that sequentially reads the key code signals recorded on a videodisc in order to discriminate field, frame, or track. A mistracking pulse generator temporarily stores two key code signals that were consecutively read from the reading device, compares the two stored key code signals and detects the occurrence of mistracking from the two key code signals, and at the same time, generates mistracking pulses in an expanded blanking time, in a number that corresponds to the number of tracks travelled in the opposite direction to the playback shifting direction when the mistracking was detected. A forced driving device forcibly shifts the playback tracks one track at a time in the playback shifting direction with every mistracking pulse impressed from the mistracking pulse generator.

  • Patent number: 4485302
    Abstract: A radiation image recorded in a stimulable phosphor is read out by stimulating the phosphor with a stimulating ray to have the phosphor emit light and detecting the emitted light with a photodetector. A radiation image information thus obtained is read out by a photodetector by way of a light guide member which collects the light emitted by the phosphor and guides the collected light to a photodetector. The light guide member is made of a transparent sheet having smooth surfaces for effecting total reflection. The light guide member has a linear or arcuate end to be located adjacent to a scan line of the stimulable phosphor to receive and guide the light emitted by the phosphor and an annular end to be located adjacent to the light receiving face of the photodetector. The light entering the light guide member through the flat end is guided to the annular end by repeated total reflection.

  • Patent number: 4484124
    Abstract: In a disk drive system which uses as stepper motor, overshooting of the desired final position is reduced by short-circuiting the windings of the stepper motor which normally remain open-circuit or are switched off. This short-circuiting provides a current path for any EMF induced in the unused windings. This effect is achieved by connecting a pair of transistors in parallel with each other and with each respective winding. The transistors are connected in opposite polarity to provide a short-circuit regardless of the polarity of the EMF across the windings. The transistors are connected to a microprocessor which is programmed such that the windings are selectively short circuited and the short circuits are applied at a predetermined time with regard to the step so that `damping` is optimized. The microprocessor may be programmed to switch the transistors on and off as desired giving flexible timing to suit different conditions. One or more stepper motor steps may be treated in this manner.
