  • Patent number: 4939580
    Abstract: A picture reading apparatus is disclosed which comprises a camera which converts a picture to be read to an electric signal, a supporting member for supporting the camera movably, and a voice input unit. A control device serves to minimize the output from the voice input unit during movement of the supporting member. Thus while a mechanism for moving the camera is in operation, the output from the voice input unit is minimized to suppress the output of operational noise. Video output is inhibited during camera movement.

  • Patent number: 4884909
    Abstract: A low cost, compact ink jet recording apparatus effectively uses a single drive source for controlling paper feed and discharge operations. The apparatus comprises a feed mechanism for feeding a sheet to be printed, discharge rollers for discharging the printed sheet, a moving mechanism for engaging and disengaging the discharge rollers, and a single drive source for operating the feed mechanism, the discharge rollers and the moving mechanism. The apparatus increases sheet feeding reliability by disengaging the discharge rollers during printing. Because the sheet feed mechanism, moving mechanism and discharge rollers are operated by a single drive source, a simpler structure is possible.

  • Patent number: 4075100
    Abstract: A dialysis unit and a dialysis apparatus employing the dialysis unit which can perform dialysis at a very high efficiency. The unit comprises a vast plurality of semi-permeable hollow fibers substantially equal in length, which fibers are gathered to form a bundle and bonded in liquid-tight connection at both ends portions thereof. This bundle of hollow fibers is loosely encased in a casing having a plurality of openings substantially uniformly distributed all over the casing. The dialysis unit is put in a dialyzate bath having therein a means for making a forced current of the dialyzate. The dialyzate flows into the casing through the openings and acts upon the bundle of hollow fibers from all directions. Accordingly, the dialyzate can flow freely inside and outside the bundle, while maintaining good contact between the dialyzate and the surfaces of the fibers, even in the inner portion of the bundle.
