Abstract: An object of the invention is to provide a high-frequency line-waveguide converter in which a distance between a grounding conductor and a radiating conductor and a thickness of a dielectric layer of a high-frequency line can be freely set. A high-frequency line-waveguide converter for converting a high-frequency line to a waveguide comprises a high-frequency line including a first dielectric layer; a line conductor; and a grounding conductor; an opening portion of the grounding conductor; a second dielectric layer; a radiating conductor; a connecting conductor; a shielding conductor portion; and a waveguide.

Abstract: A connection structure for dielectric waveguide lines, which includes dielectric waveguide lines including dielectric substrates, a pair of main conductor layers, dielectric substrates parallel with one another being sandwiched therebetween, two rows of side-wall through conductor groups arranged at intervals less than one half of a signal wavelength in a transmission direction of high-frequency signals, so as to electrically connect the pair of main conductor layers, and a sub conductor layer disposed between each pair of main conductor layers in parallel with the main conductor layers and electrically connected with the side-wall through conductor groups. The waveguides are stacked so that the main conductor layers partly overlap each other to define an overlap part, in which a coupling window is formed. This allows design freedom and easy fabrication.

Abstract: An automatic programming apparatus is provided to generate a NC program for processing a roll having a cylindrical part and axle parts. The apparatus includes a roll-profile setting module, a process-condition setting module, a process-order setting module and an automatic programming module. The roll-profile setting module establishes dimensional values of the roll between an operator and the apparatus at every locational code, while the process-condition setting module establishes a plurality of process conditions at every process code, interactively. The process-order setting module combines the locational codes with the process codes at every process order, optionally and interactively, so that the process order of the cylindrical part and the axle parts is set while allocating any one of the process conditions.

Abstract: A method of measuring a roll diameter of a roll is provided. At first, a step-shaped conical master roll consisting of a plurality of diametrical parts is prepared and then, the diameters of the diametrical parts under predetermined standard temperature are measured. After mounting the master roll on a roll grinder under a temperature condition similar to that surrounding the roll mounted on the roll grinder, a diameter of one diametrical part, of which standard diameter is closest to the roll diameter of the roll, is measured. Next, a difference between the diameter value of the diametrical part and the standard diameter value is calculated as a correction value, so that the roll diameter value of the roll is corrected by the correction value.

Abstract: A dual inline package switch assembly containing one or more separate electrical switches is disclosed which comprises an insulating housing consisting of a base and a cover to provide an interior space. The cover has at least one slit extending into the interior space in alignment with the switch. At least one actuating member is movably provided within the interior space and is formed integrally with an operating stub positioned in the slit for selectively braking and making an electrical connection between a pair of contacts fixed on the base in aligned and spaced relation. The slit has a center neck whose width is slightly smaller than the diameter of the operating stub for detenting movement of the actuating member. The actuating member side walls is positioned on housing base rails to maintain constant pressure between the actuating member conductive bridging strip and fixed pair of contacts.
