    摘要: In a printing system in which a roll film is rolled out to be printed by a printer and the film is rolled up after printing and drying, there is a possibility that wrinkles of the film are generated when printing, and printed materials are scratched because the printed film is positioned near the printer. Both end side of a suction stage in the film delivery direction are formed in a circular arc shape, and auxiliary stages are provided near the end portions to suck and hold a film, the auxiliary stages are allowed to be moved lower than a surface of the suction stage in the state to closely attach the film to the suction stage while applying tension to the film, and the film is sucked and held on the suction stage in the state to be printed after position adjustment to a surface of a mask.

    摘要: An FM detector is constructed of a phase shift network and an analog multiplier. The analog multiplier includes a differential amplifier circuit and a phase detector circuit. The differential amplifier circuit includes differential pair transistors which are driven by FM intermediate frequency signals. One of the differential pair transistors has another transistor connected thereto which is also driven by the FM intermediate frequency signal. A collector signal of either one of the differential pair transistors is applied to the phase detector circuit through the phase shift network, while a collector signal of the other transistor is directly applied to the phase detector circuit. An emitter of the one transistor and an emitter of the other transistor are connected through resistors, whereby the signal-to-noise ratio of the FM detector is improved.

    摘要: A screen printing apparatus 199, 169 has a roll paper vibrating device which vibrates roll paper in contact with the lower surface of a screen mask in a direction perpendicular to a moving direction of the roll paper while the roll paper is being moved in contact with the lower surface of the screen mask. Thereby, the roll paper in contact with the lower surface of the screen mask is moved in a waveform-shape pattern. Therefore, the cumulative contact area of the roll paper on the lower surface of the mask is increased, and it is possible to efficiently remove residue, such as paste attached onto the lower surface of the screen mask of the printing apparatus and paste attached inside pattern openings of the screen mask, to maintain a good printing performance.

    摘要: A screen printing machine comprises a conveyor for conveying a substrate to a positioning station, an XY.theta. table on which the substrate is to be put, and a printing device for printing a pattern onto the substrate in a printing station. The XY.theta. table is movable in an XY.theta. plane in the positioning station and also movable along a Z-direction perpendicular to the XY.theta. plane. The machine further comprises a device for moving the printing device between the printing station and a waiting station, an image processing device and a driving device for the XY.theta. table. The image processing device recognizes a position of the substrate and calculates the respective amount of movement of the XY.theta. table in the XY.theta. plane necessary for making the predetermined relative positional relation between the printing device and the substrate. The driving device moves the XY.theta. table, based on the amounts of movement calculated by the image processing device.

    摘要: A display device structure comprising a casing, a display panel placed in the casing, a transparent covering and vibrating plate member on the front side of the display panel and an actuator for the plate member. The covering and vibrating plate member is carried on the casing through an elastic member interposed between the peripheral portion of the plate member and the casing. By this arrangement the plate member is capable of effectively generating sound outward upon reception of vibrating force from the actuator.
