The resin composition comprises a polybutylene terephthalate that contains a terephthalic acid-derived structural unit and a 1,4-butanediol-derived structural unit, for use in powder additive manufacturing, the resin composition having a value (?), defined by mathematical formula [1] below, of 40 or smaller: ?=|(MVR1?MVR0)/MVR0|×100??[1] where, MVR0 is melt volume flow rate (in cm3/10 min), and MVR1 is melt volume flow rate (in cm3/10 min).

Abstract: A powder for powder bed fusion has a grain size distribution where D10 is not less than 20 ?m and not more than 42 ?m, D50 is not less than 42 ?m and not more than 70 ?m, and D90 is not more than 100 ?m, and includes polybutylene terephthalate having a melting peak half width in a DSC chart of not less than 1° C. and not more than 10° C. The powder for powder bed fusion benefits from excellent crushability and is prevented from the elongation of the particles or the softening of the resin even when the resin has been pulverized with a rotary blade or the like, and can form a uniformly thick powder layer without vacancies in a printing process and thus can be built up into a desired article with high accuracy.

Abstract: A push-button switch (1) is arranged such that, once a user presses an operation button (8), a switch body (20) performs an operation, and light from an LED (21) passes through a transmission plate (70) and then illuminates the operation button (8). A structure (700) is provided on a lower surface (70b) of the transmission plate (70) to refract the light from the LED (21) so that the refracted light is reflected within the transmission plate (70) and then guided to an upper circumferential wall (71) of the transmission plate (70).

Abstract: A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.

Abstract: A U-shaped iron core transporting/assembling tank is divided into a first leg iron core tank for housing a first leg iron core, a second leg iron core tank for housing a second leg iron core, and a lower-yoke iron core assembling tank. The first and second leg iron core tanks are integrated to constitute an erection tank. The lower-yoke iron core assembling tank has an opening portion for opening or closing which is formed in one longitudinal side surface of the lower-yoke iron core and through which the lower-yoke iron core can be carried in or out. The lower-yoke iron core assembling tank is connected at the opening portion which is opened when the lower-yoke iron core is housed in the lower-yoke iron core assembling tank.

Abstract: An operation switch where a switch unit can be separated from an operation unit in a simple manner even when the operation switches are densely fitted is disclosed herein. The operation switch of the invention includes an operation unit that is disposed on a front surface side of a panel and operated by external pressing force, a switch unit that can be separated from a rear surface side of the panel from the operation unit, a latching unit formed on an external circumferential surface of the operation unit along an axial center direction, a latching receiving unit which is formed along an external circumferential surface of the switch unit and to which the latching unit is latched, and a release lever that releases a latching state of the latching unit and the latching receiving unit so that the switch unit is separated from the operation unit.

Abstract: A push button switch has a box-shaped base, a first operating lever and a second operating lever, wherein each of the first operating lever and the second operating lever has a substantially U shape in a plan view, wherein the first operating lever and the second operating lever are arranged on the box-shaped base pivotally about middle parts of both arms as fulcra, and wherein the first operating lever and the second operating lever connect the tips of the both arms mutually pivotally and support the tips of the both arms in a vertically movable manner, an operating cover that has a planar shape covering the connected first and second operating levers and forms an operating hole at nearly the center thereof, and a plunger, wherein the plunger has a sectional shape capable of fitting into the operating hole of the operating cover.
