摘要:
A temperature sensor (30) for use in a microwave oven includes a metallic housing (52) including a sleeve with a central passage (54), a metallic top plate (56) coupled to the metallic housing to close off a first end of the central passage, and a temperature dependent resistor sensor element (58) thermally coupled with the metallic plate. The sensor element is coupled to a signal transmission cable (62) that passes through a bottom cap (64) which closes off the other end of the central passage. The transmission cable is preferably connected to the bottom cap by soldering around the entire interface of the cable with the bottom cap. The cable includes at least 90% shielding and plastic insulation sufficient to resist temperatures up to 200 degrees centigrade. The sleeve is preferably filled with an epoxy cement that surrounds the sensor element.

An intraoral x-ray film packet is taught which includes an integrally formed comfort enhancing perimetric bracket. The packet comprises a pair of opposing outer sheets and a continuous enclosing seal bonding the two outer sheets together to form an envelope with a perimetric projection with a film chip residing in the envelope. The perimetric projection is folded over and affixed to the packet to form an integral perimetric bracket with a rounded or creased perimetric edge.
摘要:
An ultrasonic apparatus and method for cutting a non-planar workpiece (10). The apparatus includes an anvil (16) having a non-planar surface (22) for closely engaging an underside (20) of the workpiece (10). An ultrasonic horn (26) has a non-planar cutting surface (36) closely receiving a topside (18) of the workpiece (10), wherein the cutting surface (36) and the support surface (22) have complementary non-planar shapes. The ultrasonic horn (26) resonates at a predetermined frequency effect cutting of the workpiece (10). If the workpiece (10) has a heat fusible component, the workpiece (10) can also be seamed.
