    Abstract: High frequency electrical heating system is provided for heating electrically conductive parts as they are advanced, either for annealing or welding processes, and in which the electrical heating current is supplied by a solid state DC to AC inverter through a load matching and frequency control circuit that maintains the desired load current and frequency with changes in the load impedance caused by the electrically conductive parts as they are advanced. Load matching is achieved with high frequency variable reactors having a geometrically-shaped moveable insert core section and a stationary split-bus section with a complementary geometrically-shaped split bus section and a split electric terminal bus section where the insert core section can be moved relative to the stationary split-bus section to vary the inductance of the reactor pair.

    Abstract: PURPOSE: To improve sealing performance between a central panel and a skin supporting the central panel at a proper place by enabling usage of plural glass panels, and to improve heat insulating effect of an assembly and its appearance by composing an inner skin and an outer skin in the same structure. CONSTITUTION: A first skin 16 and a second skin 16' are the same, so they are molded in the same die, and each includes an outer edge 22, 22' having a flange 26, 26', a panel part 23, 23', and an inner edge 24, 24' forming an opening part in which a central panel 12 is inserted. Next, the flanges 26, 26' respectively have cut parts 28, 28' at their open ends to be jointed together, and each skin 16, 16' is provided with a second flange 30, 30' inwardly extended toward the opponent skin 16, 16'. Next, a foam polyurethane heat insulating core 20 is introduced into a cavity 32. The central panel 12 comprises two glass panels 36 substantially in parallel to each other having an interval, and a drying agent holder 38 to hold drying agent substance 40 which is provided with a slot 42 is provided between them. Each groove 43 has a sealing piece 45 comprising sealing material of rubber or similar material to that to prohibit invasion of moisture into a gap between the glass panels 36.

    Abstract: PURPOSE: To enhance strength and dimensional stability by locating a core between a pair of skins and interconnecting them using edge members. CONSTITUTION: This compression molded door assembly 10 includes a pair of opposed compression molded door panels or skins 11, 12. The interior of the door assembly 10 is filled with a foamed core 13. In order to provide means for hanging the compression molded door assembly 10 in an opening, a pair of mounting blocks 40, 41 are provided. Cutout areas 42, 43 formed in the core 13 receive mounting blocks 40, 41. The cutout area 55 of the core 13 receives a door latch retaining mechanism 56.
