Abstract: In a communication system, an in-vehicle relay device relays data between ECUs, which are each connected to a communication line in a vehicle, by communicating with each of the ECUs. Data received by a communication device from a server outside the vehicle is input to an out-of-vehicle relay device. Data to be transmitted by the communication device to the server is output to the communication device by the out-of-vehicle relay device. The out-of-vehicle relay device relays data between the server and the ECUs by passing data to and from the in-vehicle relay device. The out-of-vehicle relay device outputs, to the in-vehicle relay device, data input to the out-of-vehicle relay device, or associated data that is associated with data that was output. The in-vehicle relay device determines whether the relaying performed by the out-of-vehicle relay device is to be suspended, based on associated data output by the out-of-vehicle relay device.

Abstract: A substrate working device includes: a base; a first substrate working table and a second substrate working table movably supported on the base; an indicator provided to one of a base side member, which is formed on the base or a member fixed to the base, and the first and second substrate working tables; an imaging unit provided on the other one, which is different from the one, of the base side member and the first and second substrate working tables in order to image the indicator; and a control unit that, by causing the imaging unit to image the indicator and based on image data thereof, acquires position information related to each of the substrate working tables and that moreover determines whether or not the respective substrate working tables interfere with each other at the time of movement of each substrate working table based on the position information.

Abstract: A board printing apparatus includes a board working table, a first printing table, a second printing table, and a control portion controlling printing operations. The control portion is configured to perform second printing on a board held by the board working table by a large component mask of the second printing table after a first printing performed on the board held by the board working table by a small component mask of the first printing table.

Abstract: Provided is a solder supply method of supplying, onto a mask sheet, solder to be printed on a printed circuit board. The method includes calculating an amount of solder supplied for a plurality of points in an X direction that is a lengthwise direction of a squeegee, and changing the amount of solder supplied at each point in the X direction based on a result of the calculation.

Abstract: Provided is a switch device that enhances the operation feeling of a rod. Two movable contact points (19) that are combined differently depending on whether a rod is operated by tilting upward, downward, leftward, or rightward while in an L position or an R position are moved and operated from an off position to an on position by an upper plate (44) or a lower plate (45).

Abstract: An inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. A pair of substrate supporting tables juxtaposed in a specific direction is provided. Screen printing is alternately performed by a single print executing section in a common area which can be shared by the two substrate supporting tables. In doing so, when one substrate supporting table located at a print position among the pair of substrate supporting tables starts exiting the print position, the other substrate supporting table starts entry to the print position.

Abstract: Disclosed is an inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. The screen printing machine comprises a pair of substrate supporting tables provided to hold a respective substrate that is a print object and which is juxtaposed in a direction that is perpendicular to a conveying direction of the substrate, and a print executing section that performs a printing process alternately on the substrate held by the pair of substrate supporting tables. Due to the print executing section being driven in the direction under control of a control unit, a print position where the substrate supporting tables execute alternate printing is changed within a range in which one of the pair of substrate supporting tables and the other of the pair of substrate supporting tables oppose each other in the direction.
