    摘要: A reflow apparatus for soldering has a tunnel and a pipe which form an endless passageway for hot gas. Infrared panel heaters are disposed inside the tunnel for heating printed circuit boards which travel through the tunnel on a conveyor. Hot gas is made to circulate through the passageway by a flow-producing device. A filter is disposed in the passageway for removing particles from fumes which are formed during soldering.

    摘要: A method and device of performing plating of an item having a row of fine parts, e.g. a flatpack IC are disclosed. The method comprises immersing said item in a bath of molten solder, removing said item from said bath while maintaining said item in an attitude such that said row of fine parts is sloped with respect to the surface of said molten solder, and causing flux to exert a fluxing action on said molten solder which adheres to said fine parts, thereby decreasing the surface tension of the solder adhering to said fine parts and preventing bridges of solder from forming between said fine parts.

    摘要: The disclosed position measuring device includes a position sensitive detector and a processing circuit therefor. The position sensitive detector includes two terminals carrying signals that vary oppositely according to the incident light. A switch connected to one terminal opens and closes the one terminal, and a signal processor processes one output of the position sensitive detector when the switch is opened and another output of the position sensitive detector when the switch is closed so as to produce normalized light/point position information. A control controls the signal processing circuit and the switch.

    摘要: In the disclosed liquid crystal display system, one of two opposing base plates that sandwich an electrooptic liquid crystal between them is divided into separate electrodes or constitutes a homogeneous transparent resistance. A source of power energizes this electrode so as to produce a gradient or stepped voltages between the divisions, and a data voltage is applied to the other electrode so that one section of the sandwiched electrodes can effect light differently than the other sections and thereby display information.

    摘要: The invention provides a method for instantly dyeing a sewing machine thread without interrupting the stitching operation with a sewing machine. The method comprises the steps of adding a dyestuff and/or pigment to a photo-setting resin solution to prepare a dyeing liquid, applying the dyeing liquid to the thread to be colored and subjecting the thread to irradation of ultraviolet rays for setting the dyeing liquid, thereby forming a colored film on the thread. The photo-setting solution is set or hardened by ultraviolet rays, by radical polymerization, cationic polymerization and cross-linking reaction.

    摘要: In the disclosed indicating apparatus, an alarm operates an indicator when a light measuring system measures abnormal lighting. A latch latches the alarm in response to a shutter release to indicate that the shutter is open. A switchover device changes the alarm signal in response to the end of an exposure. According to one embodiment of the invention, the indicator displays the alarm condition while the shutter is open. According to another embodiment of the invention, the indicator assumes a condition constituting a substate of the alarm condition.

    摘要: The present invention relates to a liquid crystal cell having a plural number of electrode pairs arranged on both sides of the liquid crystal matter so as to be opposed to each other, being characterized in that a pulse wave generating device for generating the first pulse wave with smaller amplitude than the threshold valve for lighting the liquid crystal and the second pulse wave with larger amplitude than the threshold value for lighting the liquid crystal in reversed phase to each other and a gate device for selectively applying the outputs of the pulse wave generating device to each electrode of the liquid crystal cell in accordance with the input signal are provided. Thus only the voltage between the selecting electrodes is highter than the threshold value. An input change over device is provided so as to change over the input signal group in a time dividing way in such a manner that a plural number of dots can be displayed visually at the same time, as a result, the wiring is simplified.
