Abstract: A method of manufacturing a waveguide includes forming two waveguide units, each waveguide unit having a channel defined by a bottom wall and two side walls generally transverse to the bottom wall, flanges extending from the side walls, outside the groove, transverse to the side walls and generally parallel to the bottom wall, the flanges including though holes; joining the two waveguide units to each other so that the flanges of a first of the waveguide units abut the flanges of a second of the waveguide units, with the grooves forming a channel for guiding waves; and, by insert molding, forming a thermoplastic resin cover that fills the through holes in the flanges and covers both of the first and second waveguide units, at least partially.

Abstract: A first resin is prepared which has a content of electrically conductive particles adjusted in the range from 60 wt % to 90 wt %, and a melt shear viscosity adjusted in the range from 1×103 Pa.sec to 1×107 Pa.sec. A second resin is prepared which has a content of electrically conductive particles that is adjusted in the range from 50 wt % to less than 90 wt % and that is less than that of the first resin. The second resin has a melt shear viscosity adjusted in the range from 1×102 Pa.sec to less than 1×105 Pa.sec. A resin block prepared from the first resin is placed in a mold, and the second resin is injection molded into the mold while heating the mold to the melting temperature of the first resin or above.

Abstract: Conventional batteries are disadvantageous in that a firm outer case must be used to maintain an electrical connection between electrodes, which has been an obstacle to size reduction. Those in which each electrode and a separator are joined with an adhesive resin suffer from conflict between adhesive strength and battery characteristics, particularly ion conductivity and internal resistivity. To solve these problems, it is an object of the invention to reduce resistance between electrodes, i.e., internal resistance of a battery to improve battery characteristics while securing both insulation function against electron conduction and ion conductivity between electrodes and also to maintain adhesive strength enough to firmly join the electrodes thereby to provide a light, compact and thin battery. The internal resistivity can be diminished by joining a positive electrode and a negative electrode with an adhesive resin layer having at least one adhesive resin layer containing a filler.

Abstract: Conventional separators had a function that their melting made minute holes inside the separator smaller, leading to cut off of ion conductivity in temperature increase due to unusual conditions such as short circuit. However, there was a problem that, at a temperature higher than a certain degree, not only the minute holes were closed but also the separator itself was melted to cause deformation of the separator such as shrink and generation of holes due to melting and insulation was broken. The present invention has been carried out in order to solve the above problems. The separator for batteries of the present invention comprises a first porous layer (3a) containing a thermoplastic resin as a main component and a second porous layer (3b) laminated on the first porous layer (3a), which has higher heat resistance than that of the first porous layer (3a).

Abstract: First and second members 1a, 1b, each having a U-shaped groove 20 of identical width and length, are joined together so as to constitute a waveguide channel while the U-shaped grooves 20 are opposed to each other. The first and second members 1a, 1b are fixedly fastened together by fastening bolts 2 and nuts 3 in the direction in which mating surfaces 5 are pressed together. Fastening force caused by the bolts 2 and the nuts 3 is depicted as circles 40 projected onto the mating surfaces 5 of the first and second members 1a, 1b. The bolts 2 and the nuts 3 are arranged such that lines of intersection (junction ridge lines) 6, each defined between a wall surface of the waveguide channel and the mating surface, are included in the respective projected circles 40.

Abstract: After through holes (25) are formed on flange portions (23) of a pair of waveguide units (20) and (21), and the pair of the waveguide units (20) and (21), in which the through holes (25) have been formed, are joined together, insert molding of the pair of the joined waveguide units (20) and (21) is executed using a thermoplastic resin to form a resin cover (30) filled into the through holes (25) and covers the pair of the waveguide units (20) and (21). Accordingly, an improved assembling efficiency, stronger fastening force between waveguide units, and better air-tightness of the waveguide are obtained by using resin molding to fasten the pair of the waveguides.
