Abstract: A liquid crystal display device includes a pair of first and second transparent substrates having first and second transparent conductive films formed on opposing surfaces, with liquid crystal between the first and second transparent substrates. An airtight seal encapsulates the liquid crystal, and includes a conducting portion which electrically interconnects the transparent conductive films. The transparent conducive films have metal thin films deposited on respective surface portions, including the conducting portion. A driving circuit is connected to the metal thin films, to control the liquid crystal. Spacer members are mixed and generally evenly dispersed in the seal, for controlling the thickness of the seal, which comprises first spacer members mixed in the conducting portion, and second spacer members mixed in portions of the seal other than the conducting portion. The first spacer members have a particle diameter smaller than that of the second spacer members by a predetermined value X.

Abstract: An apparatus for cleaning printing cylinder comprising a cleaning head 3 is disposed in parallel to the printing cylinder so as to be attachable and dettachable to the overall width thereof, and the cleaning is carried out by pressing said cleaning head 3 against the printing cylinder 1. The cleaning head 3 comprises a cleaning case 9 having a suction port 8 at the upper part thereof and a wind chest 10. The interior of the cleaning case 9 is partitioned into the front 11, the rear 12, and the middle part 13 with respect to the direction of the rotation of the printing cylinder 1, with the front 11 and the rear 12 being, respectively, fitted with cleaning members 14, 15 and the middle part 13 being fitted with a lip 16 composed of an elastomeric material. Between the lip 16 and the front 11 and beneath the rear 12 there are formed slits 17, 18 which have suitable gaps, and both of them communicate with the wind chest 10.

Abstract: A tape recorder with improved cue and review operations is disclosed, wherein there is provided a cue/review engagement part which is engageable with a rotary shaft supporting an idler wheel and is capable of moving said rotary shaft so as to separate the idler wheel from a take-up reel when high speed rewind or fast/forward is desired and the engagement part is also engageable with a pinch roller actuator for disengaging the pinch roller from pressing the tape during cue or review operation.
