The powder application apparatus further comprises a first powder supply channel provided in a second part of the powder application apparatus and configured to discharge raw material powder from the first powder storage onto a carrier located below the apparatus. A first channel opening/closing element is configured to be moved between a first position to allow the discharge of raw material powder from the first powder storage onto the carrier, and a second position in which the discharge of raw material powder from the first powder storage onto the carrier is presented.

Abstract: Disclosed is a substrate processing apparatus, including: a processing chamber for processing a substrate; a substrate rotating mechanism for rotating the substrate; a gas supply unit for supplying gas to the substrate, at least two kinds of gases A and B being alternately supplied a plurality of times to form a desired film on the substrate; and a controller for controlling a rotation period of the substrate or a gas supply period defined as a time period between an instant when the gas A is made to flow and an instant when the gas A is made to flow next time such that the rotation period and the gas supply period are not brought into synchronization with each other at least while the alternate gas supply is carried out predetermined times.

Abstract: System and method for operating a material deposition system are disclosed. In one embodiment, the method can include periodically injecting a precursor into a vaporizer through an injector at the vaporizer, vaporizing the precursor in the vaporizer and supplying the vaporized precursor to a reaction chamber in fluid communication with the vaporizer, and shutting down the vaporizer and the reaction chamber after a period of time. The method can also include conducting maintenance of the injector at the vaporizer by using a vapor solvent rinse.

Abstract: A method and a plasma system are provided for anisotropically etching structures into a substrate positioned in an etching chamber, e.g., structures defined using an etching mask in a silicon substrate, using a plasma. For this purpose, the etching chamber is supplied at least intermittently with an etching gas and at least intermittently with a passivation gas, the passivation gas being supplied to the etching chamber in cycles having a time period between 0.05 second and 1 second. In the plasma system, in addition to a plasma source, via which the plasma acting on the substrate may be produced, an arrangement is provided for at least temporary supply of the etching gas and at least temporary supply of the passivation gas to the etching chamber, which arrangement is designed in such a way that the passivation gas may be supplied to the etching chamber in cycles having a time period between 0.05 second and 1 second.

Abstract: An apparatus for applying a coating to the head-shank junction of externally threaded fasteners in an automated fashion. The fasteners are positioned, head down, on rotating part holders positioned about the periphery of a rotating disc. The part holders may be magnetic or other forms, and are adapted to maintain the fasteners in a generally fixed position during their movement. The fasteners are pre-heated at a heating station during their rotational movement on the disc. A dispenser is then used to apply the coating to the articles, in timed sequence to the movement of the articles. In this fashion, a coating can be applied to selected portions of the entire periphery of the head-shank junction. A method for applying a coating to the head-shank junction of externally threaded fasteners in an automated fashion also forms part of the present invention.

Abstract: A paste applicator for drawing a paste film in a desired pattern on a substrate, including a table for detachably supporting a substrate, a paste reservoir tube to be filled with a paste, and a nozzle communicating with the paste reservoir and having a paste discharging port opposing to an upper surface of the substrate mounted on the table. A device is supplied for changing the relative positional relationship between the nozzle and the substrate mounted on the table. The paste is applied onto the substrate to form a desired pattern of the paste. A measuring device measures a position of a paste discharging port of a nozzle exchanged together with the paste reservoir tube by using a paste pattern formed by applying the paste onto the substrate held on the table using the exchanged nozzle. The center of the paste pattern nearly agrees with the center of the paste discharging port.

Abstract: An easy to use and inexpensive programmable electronic control system is provided for control of glue guns to spot glue on controllable positions on a carton blank, being conveyed past a glue station. The controls are synchronously related to the position of a workpiece on a conveyor platform by means of a rotary shaft in the conveyor mechanism to which a rotating timing wheel is coupled for precisely and synchronously identifying positions along the length of the workpiece. One or more solenoid actuated glue guns, may be positioned in preselected lanes across the width of the workpiece. By means of markers rotated by the timing wheel and an optical sensor coupled to a position adjacent the moving marker controls the glue dispensers. By means of a small diameter fiber link between the optical sensor and the marker, precise timing and control of glue dot positions is achieved for high fidelity and high speed response.

Abstract: The present invention discloses a method and apparatus for coating adhesive for mounting parts onto a printed substrate in which an adhesive coating nozzle is arranged in correspondence to the printed substrate placed on an X-Y table controlled to be moved in an X-Y direction, and said coating nozzle is operated to coat the adhesive within an adhesive storage tank in position on each of the printed substrates, at which a waste coating is carried out for said coating nozzle before the latter perform the coating operation with respect to the printed substrate, whereby even if the adhesive trickles from the end of the nozzle to bring forth the liquid-drip state, the adhesive in the liquid-drip state is eliminated by the waste coating of the coating nozzle to prevent the adhesive in the amount more than as needed from being coated on the printed substrate, thus always maintaining a stable amount of coating thereby positively preventing occurrence of irregularities in quantity.

Abstract: A variable sweep means connects the rotating shaft of an electric motor to a rotatable gas manifold in a rotary disc reactor to convert rotation of the shaft into reciprocating oscillation of the gas manifold. A cycle timing control means for varying electric motor speed at two independent speeds is connected to the electric motor. The control means varies the oscillation speed of the gas manifold at two sweep rates by varying electric motor speed automatically during each sweep cycle.

Abstract: This invention relates to a method of and apparatus for forming a colored shade band on an elongated area of a flexible sheet of interlayer material comprising applying a dye composition by electrostatic spraying against an elongated area of a surface of a flexible sheet of non-conductive interlayer material such as polyurethane or plasticized polyvinyl butyral. A flexible sheet to be coated is mounted on a support carriage at a loading and unloading chamber in a substantially horizontal support plane, is transferred to a coating chamber, is tilted into an oblique plane at said coating chamber where it is aligned with a platen mask, electrostatic spray means disposed to one side of said platen mask supplies an electrostatic spray of a dye composition through said platen mask to the elongated area of said flexible sheet.

Abstract: This invention includes timer means in combination with switching means disposed in a copying machine for cyclically and automatically activating a pump which circulates liquid developer through the copying machine for a predetermined period of time thereby periodically mixing the toner particles and dispersant in the liquid developer while also rotating the copier drum through an incremental angle thereby periodically immersing each section of the drum surface in the liquid developer reservoir.

Abstract: Tinning of a plurality of solder bonding surfaces is accomplished by feeding a predetermined length of solder into each of the plurality of pre-heated surfaces. The apparatus provides for the measurement of the solder wire during a non-tinning portion of the machine operating cycle, thereby conserving cycle time.
