Abstract: A multi-pole group-operated switch (10) is provided for electrical power distribution circuits. The switch (10) is self-contained and suited for ease of use with various line spacings and arrangements of the distribution lines; e.g., side-by-side (horizontal plane), phase-over-phase, and cable drops. The switch includes a plurality of switch-pole units (12,14,16) carried at desired spacings by a base support and drive arrangement (20,24). Each of the switch-pole units includes a housing (114 of 70), interrupting contacts (21,23), and disconnect contacts (42,80). The housing (114 of 70) that encloses the interrupting contacts (21,23) is movable to perform the disconnect function. The base support and drive arrangement (20,24) encloses a high-speed interrupting linkage (20) for operation of the interrupting contacts (21,23) of each of the switch-pole units (12,14,16) and carries an operating mechanism (18) that is connected to the interrupting linkage (20) internal to a base support member (24) of the base support and drive arrangement (20,24). The switch (10) also includes a disconnect linkage (72) to move the switch-pole housings (114 of 70). For manual operation of the disconnect function, an operating handle (76) is provided. The operating handle (76) and the operating mechanism (18) are oriented and positioned relative to the switch in various predetermined locations that are desirable for the particular mounting configuration of the switch with respect to the line layout and the equipment pole. In a preferred embodiment, the switch includes integral dead-ending connection provisions (34 via 102,103) and also includes integral line-parameter sensing and power-supply provisions (e.g. 38,44) incorporated within one or more of the switch-pole units (12,14,16).

Abstract: The invention relates to a night sight which comprises a large-aperture lens (1), a light-amplifying tube (2) for amplifying the image which is projected by the lens and an ocular (3) through which an observer can view the amplified image. An IR sight is arranged in connection with the large-aperture night sight lens, the IR sight's lens (5) being preferably situated in a central obstruction (4) in the night sight lens, and the IR light is converted to visible light via a detector/­luminescent diode array (6, 7) after which the image produced in the IR sight is reflected into the night sight lens (1) and is amplified by the light-amplifying tube (2). By combining the two night systems, a target which is "invisible" to the light-amplifying sight alone can be located with the aid of the IR addition. Due to the fact that the luminescent diode signals are amplified via the light-amplifying tube, these signals do not need to be strong. The equipment can be made light and un­complicated.

Abstract: The waste material is introduced into a container and degraded microbially while air is fed in. The waste air which emerges from the material to be composted is recycled to the material to be composted. To start up composting rapidly and reliably during the initial phase, the waste air which emerges from the material to be composted is recycled to the material to be composted during the initial phase. When, after a predetermined time of preferably 1 to 5 hours, the temperature in the material to be composted has not risen, the air is circulated. However, the air can also be circulated from the outset, that is to say, the waste air emerging from the material to be composted can be recycled to the material to be composted.

Abstract: A method of fabricating a CMOS structure (30) that may be integrated into a BICMOS process flow includes forming N and P type doped wells (32) in an isolation module (10). A first conformal nitride layer (34) is formed on the surface of the isolation module (10) and portions of the nitride layer (34) disposed over the doped wells (32) are removed. After forming a gate oxide layer (36) on the doped wells (32), a conformal polysilicon layer (38) is formed and doped on the surface of the structure-(30). The conformal polysilicon layer (38) is etched into gate electrodes (40) which are used as a mask for the self-aligned implant of first portions of source and drain regions (42) in the doped wells (32). Dielectric spacers (44) abutting the edges of the gate electrodes (40) are formed and the implantation of second portions of the source and drain regions (42) is self-aligned to the dielectric spacers (44). Following the formation of a conformal nitride layer (46) and a conformal oxide layer (48), the structure is planarized and source, drain and gate contacts (58) are formed.

Abstract: In surface packaging of thin resin packages such as resin molded memory ICs or the like, cracks of the package occur frequently at a solder reflow step where thermal impact is applied to the package because the resin has absorbed moisture before packaging. 
     To solve this problem, the devices are packaged moisture-tight at an assembly step of the resin molded devices where the resin is still dry, and are taken out from the bags immediately before the execution of surface packaging.

Abstract: A safety mechanism for a refrigerator (5) for a vehicle container (2), is provided, the refrigerator (5) being mounted on the container (2) and having a motor operated compressor (6), which is supplied with a motor-driving current through a main current route extending from an alternating current generator (3) provided on the vehicle (1) or an external power source (40) to the motor operated compressor (6). The main current route has a connector (22,14,15) provided in a connection box (25) with a door (30). A door switch (32) which is on-off operated depending on the opening and closing operations of the door (30) of the connection box (25), and a control unit (16) which controls the main current route in accordance with the operation of the door switch (32) to its continuity condition when the door (30) is closed and to its break condition when the door (30) is opened, are provided in the safety mechanism. Since the main current route is broken when the door (30) is opened before the connector (22,14,15) is cut off, the main current is cut off when the switch is opened and arcing is prevented between the contacts in the connector (22,14,15).

Abstract: The invention provides a FET by forming a channel layer (33) including "n" type impurity at high concentration, said channel layer (33) being sandwiched by a first semiconductor layer (32) and a second semiconductor layer (34) lightly doped with impurity. Therefore, even when electrons in the channel layer (33) obtain high energy, the electrons in this arrangement rush out essentially to the second semiconductor layer (34) excelling in electron carrying characteristic, thus travelling speed of the electrons in the channel layer (33) is not lowered. Furthermore, as the channel layer (33) is thinly formed and allowed to include impurity at high concentration, the current drive capability can be improved.
