Abstract: Printed sheets are delivered from a printer to a coating machine which feeds the sheets successively to a coating nip formed between a coating cylinder and an impression cylinder. A transport mechanism advances the sheets through the coating nip. The arrival of each sheet is sensed, and a control unit determines a speed necessary for each sheet to be initially fed in order to reach the coating nip simultaneously with an image area of the coating cylinder and with grippers of the transport mechanism, as well as at a speed equal to a surface speed of the coating cylinder. Independently driven rollers advance each sheet at that sheet's determined speed (e.g., acceleration or deceleration).

Abstract: The invention relates to a method and an arrangement in connection with coating of an optical fibre, in which a first fibre (3a) is directed from a fibre pay-off forward in the process via a press head (2a) forming the coating, and when the first fibre (3a) ends, a new fibre (3b) is directed to the press head (2a) in advance, and when the first fibre (3a) ends, a roll device (7) grips both the first fibre and the new fibre so that both fibres (3a, 3b) are caught between freely rotating rolls (7a, 7b) of the roll device (7), whereupon the tail of the first fibre (3a) makes the rolls (7a, 7b) of the roll device rotate, and the rotational movement of the rolls pushes the new fibre (3b) to the press head (2a) at a speed equal to that of the line.

Abstract: In a vacuum processing chamber, a monitoring arrangement for detecting when a substrate is sufficiently dechucked by an electrostatic clamp to allow safe movement thereof by a transfer mechanism such as a pin lifter. The monitoring arrangement includes an acoustic generator which outputs a sound wave at the resonant frequency of the substrate and the dechucking condition is detected when the sound wave is adsorbed by the substrate. The arrangement can be used during processing of wafers such as plasma etching or chemical vapor deposition.

Abstract: A thin-film depositing apparatus of the present invention deposits a sputtered film on a substrate in a sputtering chamber, and removes the substrate having the sputtered film deposited thereon from the sputtering chamber via a load-lock chamber by a robot arm. As a system for controlling the sheet resistance of the sputtered film deposited on the substrate, a measuring device using an eddy current method is mounted in the proximity of a substrate outlet of the load-lock chamber and measures the sheet resistance of the sputtered film of the substrate removed from the substrate outlet. With this structure, it is possible to provide a thin-film depositing apparatus which stably measures the sheet resistance of a thin film deposited on a substrate and performs feedback of the measurement result to control the film deposition conditions so that a thin film to be deposited on a subsequent substrate has a desired thickness.

Abstract: A glue gun type gluing apparatus has glue guns 8a and 8b for applying glue to a gluing area in a joint flap 2 of a corrugated board sheet 1 for manufacturing a box, which runs on a box manufacturing line, a sheet end detection sensor 3 for detecting the front and rear ends of the corrugated board sheet 1, an encoder 7 for measuring the travel distance of the corrugated board sheet 1, and a control unit 9 for controlling the operation of the glue guns 8a and 8b. The control unit 9 learns and stores the position of gluing area on the basis of the information from the sheet end detection sensor 3 and the encoder 7 while the corrugated board sheet 1 is run at a low speed, and restricts the acquisition of detection signals by the sensor 3 during the time from the passing of the end point of the joint flap 2 to the arrival of the start point of the next joint flap 2.

Abstract: The presence and absence of a semiconductor wafer on a wafer holder in a vacuum chamber having an optically transparent window is detected by an optical system including a source of optical energy positioned outside the chamber and a receiver for the optical energy positioned outside the chamber. A light path extends from the source through the window and an opening in the wafer holder when no wafer is on the wafer holder. The optical path is bent downstream of the wafer holder, thence continues back through another opening in the wafer holder, and through the window to the receiver. The optical receiver is positioned and arranged so optical energy reflected from a wafer (even a wafer having dispersive mirror properties) in situ on the wafer holder cannot be reflected or otherwise incident on the optical receiver.

Abstract: Apparatus to apply brazing flux to a joint between two vertically oriented parts. A reservoir containing liquid brazing flux is in liquid flow communication with a pump capable of metering a fixed amount of flux when actuated. A nozzle in liquid flow communication with the pump has a housing with an outer casing and an inner casing spaced from the outer casing to form a passageway. The inner casing is open at one end to receive the parts to be joined and has two spaced apart opposing side walls with ports in each side wall in liquid flow communication with passageway. The nozzle and parts are moved relative to each other to position the joint between the two parts adjacent the ports in the side walls of the inner casing. Actuation of the pump will deliver the fixed amount of liquid brazing flux to the joint.

The contact roller is disposed about an axis parallel to the axis of the glue roller through positioned downstream thereof in the direction of movement of the sheets, such that a guide may be located beneath the contact roller adjacent to the cladding of the roller, designed to afford support to sheets carried by the contact roller and existing from the area where the adhesive is applied.

Abstract: The invention comprises a method and apparatus for providing a coating to objects such as a lens. A bath of coating solution is provided and the objects are immersed into the solution and removed from the solution at a constantly changing speed. The speed of removal is slower at the top and bottom of the object and faster at the midpoint of the object. Thus the coating is thinner at the top and bottom and thicker at the center (where greater abrasion resistence is required). The slower speed at the removal of the bottom edge of the lens from the solution provides a thin coating and eliminates the formation of coating drip lines and puddles.

Abstract: A device for dipping plates (40) in a liquid (70) includes a plurality of elements (20) which form a number of disc-like devices secured at a certain distance from each other on a rotatable shaft (30). Each element is provided with several evenly spaced recesses for receiving the plates and each plate received rests in at least two recesses. The elements are partially immersed in the liquid. The drive mechanism rotates the shaft in steps and the recesses, together with the plates contained in them, then pass through the liquid. During the pauses between the elements rotating, a feeder device (51) pushes the plates into the recesses (21') in the elements from a feeder table (52), whereas the dipped plates are moved by an ejector device (61) to a receiving device (62. The receiving device has a number of compartments (64) with surfaces (60) located above one another, and these compartments are gradually moved into position for receiving the dipped plates.

Abstract: A couple of copy sheet stripping members are provided for scraping away a copy sheet adhered strictly to one of two rollers which are driven to fix images of an original document on the copy sheet in pressure engagement. At least one of the copy sheet stripping members is secured removably from the roller while the copy sheet is not transferred out of the rollers. The copy sheet stripping member becomes pressed against the roller in accordance with the transferring of the copy sheet which is detected by a sensing means. The copy sheet stripping member is free of residue attached on the roller because the period of time where the engagement between the roller and the copy sheet stripping member is kept is very short. The other copy sheet stripping member can be further disposed to assure both the scrape of the copy sheet and the removal of the residue on the roller, the copy sheet stripping member being continuously pressed against the roller.
