Abstract: A wire condenser element bending method and a wire condenser element bending apparatus bend two wire condenser elements by pressing the wire condenser elements against a bending roller to form two scroll wire condensers simultaneously. Inner edge parts of the wire condenser elements are held by holding devices at diametrically opposite positions on the outer circumference of the bending roller. Pressure rollers press the two wire condenser elements against the bending roller while the bending roller is rotated to form two scroll wire condensers simultaneously. Each wire condenser element serves as a separator for separating layers of the other wire condenser element.

Abstract: An air-intake manifold includes a plurality of air-intake pipes connecting between a collector and an air-intake pipe mount. Each air-intake pipe 3 is bent to have a predetermined shape. Each air-intake pipe 3 is fabricated by bending a substantially straight double metal pipe that has an outer pipe 3a and an inner pipe 3b with a clearance 3c therebetween equal to or less than 0.2 mm, such that the outer pipe 3a and the inner pipe 3b locally contact with each other at an intermediate region. Accordingly, while the outer pipe 3a and the inner pipe 3b of the air-intake pipe 3 locally contact with each other at the contact point 3e (in the relatively slidable relationship), an air layer having a thickness equal to or less than about 0.2 mm is formed between the outer pipe 3a and the inner pipe 3b at portions except for the contact point 3e.

Abstract: The positive electrode plate is a plate material which is formed by filling a foaming nickel substrate with a paste-like kneaded substance containing nickel hydroxide, and drying and pressure forming the substrate. The foaming nickel substrate is prepared by removing a plate foaming core material of urethane foam or the like after nickel-plating the foaming core material. First, the mass per unit area of nickel in the foaming nickel substrate is set to be 0.5 kg/m2 or more, so that the ohmic resistance of the foaming nickel substrate can be lower than those of conventional foaming nickel substrates. In addition, the upper limit of the mass per unit area of nickel in the foaming nickel substrate is set to be 1.1 kg/m2, so that it is possible to prevent the reduction of the energy density from exceeding the effect of the reduction of the ohmic resistance of the foaming nickel substrate.

Each of the connecting members 63 has a weak portion 64, such as a V-notch. After the spool 42 has advanced beyond the pawls 32, the weak portion 64 is broken by a second-tube-inserting force exerted on the connecting members 63 via the spool 42 and the ring member 62 on which the spool 42 is seated.

Abstract: Since it is possible to optionally adjust the used region of a negative electrode, it is possible to obtain a cell having an excellent balance of durability and discharge characteristic, and it is possible to reduce the resistance of a positive electrode. If only the positive electrode is charged before assembling the cell, it is possible to optionally adjust the used region of the negative electrode, so that it is possible to obtain the cell having the excellent balance of durability and discharge characteristic. Also after a large number of charge and discharge cycles are repeated, it is possible to suppress the internal pressure rise of the cell at the last stage of charge. In addition, it is possible to form a good cobalt conductive network on the active material of the positive electrode, and it is possible to reduce the resistance of the positive electrode.

Abstract: An intake manifold has a plurality of branch tubes each joined by brazing in a furnace at one end to a flange on the engine side and at the other end to a surge tank on the throttle chamber side. The surge tank is separated into two pieces or a brazing side member and a non-heating side member. Branch tubes are fixed in position relative to the brazing side member by peen locking with a peening tool or the like and are then joined to the brazing side member by brazing in the furnace. The non-heating side member is not subjected to the brazing in the furnace but is joined to the brazing side member by bolts or the like.
