Abstract: An electronics frame for a wired pipe drill string, including a housing arranged to be disposed within the wired pipe drill string. The housing includes a chamber formed therein and one or more electronic components disposed in the chamber. A shape memory element is disposed in the chamber. The shape memory element is transitionable in response to a transition stimulus between a first shape permitting positioning within the chamber and a second shape sealingly engagable with the housing to isolate the one or more electronic components from fluid. A method of isolating an electronic component is also included.

Abstract: An electronic circuit storage case includes a housing made of resin and having a case portion storing an electronic circuit board and a connector portion extending in a direction perpendicular to a board attachment surface of the case portion and incorporating a connector. Interior and exterior opening holes communicate at bottoms via a communication hole. A ventilating hole continuing from the interior of the case portion to the exterior of the connector portion is provided in a solid portion of the housing. The interior opening hole and the communication hole are bent in an L shape and provided to a primary resin mold part forming the housing. The exterior opening hole is provided to a secondary resin mold part of the housing enclosing the primary resin mold part and forming the connector and case portions so as to communicate with one end of the L-shaped communication hole substantially perpendicularly.

Abstract: The underground storage of operational electronic equipment utilizes a hermetically sealable container adapted for receiving electronic equipment, such as a computer hard drive. The electronic equipment is placed in the container and electrically connected via a seal maintaining feedthrough to a facility proximate the container. The hermetically sealable container is sealed up and then buried underground.

Abstract: An electronic control apparatus can be reduced in size and cost by eliminating certain parts such as a power board, etc. The apparatus includes a housing, a heat sink attached to one end of the housing, semiconductor switching elements mounted on the heat sink, a circuit board arranged in opposition to the heat sink, and a plurality of conductive plates electrically connecting the circuit board and the semiconductor switching elements. The heat sink is composed of a heat sink main body, and an anodized aluminum film formed at least on a surface of the heat sink main body at a side at which the power device is mounted thereon, and the heat sink main body has outer peripheral end faces arranged in opposition to inner wall surfaces of an opening portion of the housing.

Abstract: An electronic control apparatus can be reduced in size and cost by eliminating certain component parts such as a power board, etc. The apparatus includes a housing, a heat sink, semiconductor switching elements having terminals and mounted on the heat sink, a circuit board arranged in opposition to the heat sink, conductive plates connecting between the circuit board and the semiconductor switching elements, and a cover receiving the semiconductor switching elements and the circuit board in cooperation with the heat sink. The conductive plates have the press-fit terminal portions press-fitted into the through holes in the circuit board, and the individual conductive plates are arranged along a lead-out direction in which the individual terminals of the semiconductor switching elements lead out, and are bonded to the individual terminals.

Abstract: A liquid tightly sealed housing has an electrical or electronic device arranged in an internal volume of the housing, a channel with a globally vertical main axis, passing through an upper wall of the housing to connect the internal volume of the housing to outside, and closure apparatuses for making the channel liquid-tight and gas-permeable. The closure apparatuses are arranged at least partly on the upper wall of the housing and at an upper end of the channel so as to prevent any liquid accumulation in the channel.

Abstract: An electronics module configured for use within a vehicle fuel tank. The electronics module includes a fluid encapsulant, and electronics immersed in the fluid encapsulant. Preferably, the electronics module includes a sealed housing for carrying the fluid encapsulant and electronics therein, and the fluid encapsulant includes a base fluid and additives to the base fluid to neutralize aggressive compounds in any fuel that may enter the sealed housing.

Abstract: A liquid tight connector for terminating one end of an elongate electrical conductor includes a connector body having a rearward conduit receiving end, an opposed forward end and a central bore therethrough. A gland nut is movably secured to the rearward conduit receiving end of the body for securing the end of the conduit thereto and a sealing ring is interposed between the rearward conduit receiving end of the body and the gland nut and is supported within a receiving chamber defined therebetween. The sealing ring has a generally O-shaped cross section and is formed of resiliently deformable material. The gland nut includes an internal frusto-conical surface, which simultaneously urges the sealing ring radially inward toward the conduit and forward toward the rearward conduit receiving end of the body so as to deformably fill the receiving chamber upon the movable securement of the gland nut onto the body.

Abstract: A bushing is provided for placement on a cable to be held between an upper cover and a lower cover of an apparatus. The bushing has a flange on an outer peripheral surface thereof, and the flange extends perpendicular to the cable on which the bushing is put. The upper cover and the lower cover of the apparatus are attached to form a unit, and the upper cover comprises a flange receiving portion. The flange comes closely into contact with the flange receiving portion to fix the cable against the upper cover and serve as a watertight packing. As a result, a simple watertight structure is provided.

Abstract: A module is placed inside a chamber that can be sealed hermetically. The module includes a substrate incorporating a plurality of electronic circuit parts, a frame connected to the substrate so as to enclose the plurality of electronic circuit parts, and a cover placed facing the substrate and connected to the frame so as to cover an opening portion of the frame. The pressure in the chamber is reduced to a first pressure P1, and then the pressure is increased from the first pressure P1 to a second pressure P2. A liquid is filled into the module through a hole formed in the cover within the chamber, and the pressure inside the chamber is increased from the second pressure P2 to a third pressure P3. Then, the hole of the cover in the chamber is closed to seal the module hermetically, thereby sealing the liquid in the module. Thereafter, the pressure in the chamber is increased from the third pressure P3 to an atmospheric pressure P0, and the module is taken out of the chamber.

Abstract: A container box for use in a communication apparatus. The container box has a container case defining an internal space; partitions connected to the container case for partitioning the internal space to have at least two accommodating chambers; and a container cover corresponding to each of the at least two accommodating chambers. Each cover is connected to the container case for independently closing and opening the at least two accommodating chambers. Wherein the at least two accommodating chambers each have differing degrees of waterproof level.
