Abstract: An electrode material capable of making more satisfactory the dispersion at the time of production and the aging property of a resonator than Au and capable of reducing the price as compared to Au. An resonator electrode material including a ternary alloy composed of Au and two metals M1 and M2, and being used as an excitation electrode to excite oscillation in a piezoelectric element, wherein the two metals M1 and M2 are, respectively, (a) metal M1: a metal exhibiting a tendency to decrease the temporal frequency property (?f1/f1) from the reference value f1, and (b) metal M2: a metal exhibiting a tendency to increase the temporal frequency property (?f1/f1) from the reference value f1. The metal M1 is preferably at least any one of Ag, Al and Ni, and the metal M2 is preferably at least any one of Pd, Ru, Pt, Ir, Rh and Cu.

Abstract: In a part catalog creating system, a part table containing design change numbers respectively set for parts, and header numbers, part numbers, and quantity of the parts, each of which corresponds to the design change numbers, is created, and product number data that contains design change number of part used for manufacturing each product is created, and information that coincides with the product number data is selected from the part table, thereby creating a product number list. The product number list and images of parts corresponding to the product number list are combined and the part catalog data for each product number is output. Thus, the part catalog can be easily created without errors.

Abstract: A surface mount quartz crystal unit has a substrate for surface-mounting, a pair of connecting electrodes disposed on a principal surface of the substrate, a quartz crystal blank, and a ridge corresponding to the end of the crystal blank and disposed on the substrate in spaced relation to the connecting electrodes. The ridge has a height greater than the thickness of the connecting electrodes. An electrically conductive adhesive is applied to the connecting electrodes, a spacing between the connecting electrodes and the ridge, and an upper surface of the ridge. The crystal blank is fixed to the connecting electrodes by the adhesive at respective opposite sides of an end of the crystal blank to which extension electrodes are extended from excitation electrodes. The other end of the crystal blank remains lifted about the ridge from the principal surface of the substrate under shrinking forces of the adhesive.

Abstract: A turntable for an electronic range comprises: a tray-supporting element which is provided with a plurality of arms radially arranged and having rollers at end portions thereof, a substantially triangular concave portion at its lower surface, and a through-hole at its central portion; and a coupling unit which is provided with a boss portion received in the through-hole of the tray-supporting element, a substantially triangular flange portion engaged with the concave portion of the tray-supporting element, and a shaft receiving sleeve for receiving a driving shaft of an electric motor, which shaft receiving sleeve is integrally formed in a lower portion of the coupling unit.

Abstract: A latch assembly for a cabinet door of a microwave range is provided with a pivotal hook member of the cabinet door, which member is engaged with a dog projection of a hook housing mounted in a door-opening frame of a main body of the microwave range. On a peripheral portion of a cooking cabinet contained in the main body is fixedly mounted a door-opening frame on which is pivotally mounted a hook-operating lever in a lower-end portion of which is slidably mounted one end of a hook-operating rod the other end of which is brought into contact with the pivotal hook member of the cabinet door, the hook-operating rod being normally biased at its retracted position by a spring means. An upper-end portion of the hook-operating lever is brought into contact with a push pin portion of a push button which is mounted in a control panel of the microwave range in a retractable manner.
