Abstract: A method and assembly are provided for mounting a solid electrolytic capacitor onto a printed circuit board including an anode pad and a cathode pad. The capacitor includes a capacitor element which has an anode and a cathode electrically separated by a dielectric substance. The cathode includes an outer cathode terminal layer formed over the element. The method includes the steps of removing a part of the cathode terminal layer to expose a flat anode terminal surface, attaching the element to the printed circuit board for bringing the cathode terminal layer into electrical connection with the cathode pad, electrically connecting the flat anode terminal surface to the anode pad via a metal wire, and enclosing the element in a resin member for protection.

Abstract: The invention relates to an enclosure for computers that is formed by slidably joining together two chassis portions. A groove formed in a wall of one chassis portion mates with a tongue formed in a wall of the other chassis portion. The tongue enters one end of the groove and slides throughout the groove's length until the two chassis portions become fully joined and form a completed enclosure. The combination of the tongue and groove forms a slidable tongue and groove joint. When both chassis portions are made of electrically conductive material, the tongue and groove joint effectively inhibits the passage of electromagnetic radiation through the seam that forms at the juncture of the two chassis portions.

Abstract: A novel leakage radiation preventing element effectively prevents radio waves from being radiated from an electronic appliance, without depending upon a capacitor or a choke coil. The leaked current I.sub.os and I.sub.or generated from a hole or a gap formed in a casing or a chassis is introduced into a wave guide path and then attenuated by radio wave absorption function of a magnetic substance disposed therein. A coaxial conductor (2) is passed through a hole (107) formed in a chassis (3). The wave guide path (104) is formed between the chassis and a conductive disk (101) electrically floated from the chassis. A radially outward end of the wave guide path (i.e., the outer circumferential end of the conductive disk) is shorted to the chassis at high frequency, and further the inside of the wave guide path is filled with a ferrite ring (102).

Abstract: A cable locking and sealing device has an elongate body of elastomeric material formed with at least one through-passage for receiving a cable and at least one longitudinal slit extending down at least a portion of its length. The interior of the through passage is formed with a series of annular ribs which each taper in depth towards a point adjacent the longitudinal slit. When the device is pulled into an entry port, its elongate body becomes radially compressed thereby holding the cable firmly in place: however, the sealing effect of the ribs against the cable is not compromised by any relative longitudinal displacement of the portions of the body either side of the slit.

Abstract: An improved transformer cabinet includes a cabinet door in which the lower portion of the door is replaced with a durable, corrosion resistant material. It is preferred that the replacement portion comprise a strip approximately three inches wide attached to the lower edge of a transformer cabinet door.

Abstract: A power strip includes a casing on which at least one outlet is formed for the receiving of an external plug and a power cable extending from inside the casing to a terminal connector, such as a plug for connecting to an electric main. The casing is particularly provided with a window opening to expose the inside structure of the power strip with a transparent insulation cover removably mounted thereon to show the inside structure of the power strip.

Abstract: Exposed forward ends of conductors of the electric wire and the flat cable are connected to each other. The conductors of the electric wire set to a length adapted for being overlaid on the conductors of the flat cable are held in overlaid relation with the conductors of the flat cable between insulating partitioning walls formed on the upper surface of a holder for isolating each adjacent pair of the conductors of the electric wire. The overlaid portions of the conductors are thus connected in the above-mentioned overlaid relation, and are insert-molded including the connected portions, thereby connecting the electric wire and the flat cable directly.

Abstract: A cable supporting member includes a supporting section 11 having grooves 9a and 9b formed therein for receiving cables 5, and a pair of side sections 13a and 13b formed integrally with the supporting section 11. Each side section has an upper surface inclined in such a manner that its thickness gradually decreases with the distance from the supporting section 11 toward its outer edge. Installation of cables can be easily performed by fitting ordinary communication cables or the like in the grooves and laying flexible floor covering elements on the cable supporting member fitted with the cables. Since core wires need not be embedded in the cable supporting member, it is unnecessary to connect the cable on the cable supporting member to communication cables etc. Also, after installation, the outside appearance of the floor is not spoiled by the cable supporting member.

Abstract: An electric double layer capacitor including a pair of activated charcoal electrodes facing each other with the intermediary of a porous separator, and current collecting members each being positioned on a surface of the respective electrode opposite to a surface contacting the separator is disclosed. Hydrophobic powdery activated charcoal is provided around the electrodes for adsorbing gases. With this arrangement, it is possible to prevent pressure inside the capacitor from being elevated by gases produced in the capacitor, thereby enhancing the reliability of the capacitor.

Abstract: Disclosed is a hermetically sealed housing assembly for protecting electrical equipment. The housing assembly includes a hermetically sealed housing member having an exterior wall and an interior region for containing the electrical equipment. A flex tape electrical signal conductor extends through an opening in the exterior wall, and transmits electrical signals between the electrical equipment in the interior region and electrical components in a region exterior to the housing member. The flex tape signal conductor is hermetically sealed to the exterior wall of the housing member at the opening to maintain the integrity of the hermetic seal of the housing member even after temperature-cycling for a period of time.
