Abstract:
A method of highly precisely and efficiently producing spot cladding members used for lead frames of semiconductor integrated circuits such as flat packages. A metal foil and a substrate member that are fed in constant steps are temporarily spot-welded successively at predetermined regular intervals by resistance welding, ultrasonic welding or laser welding, and then undesired portions are removed by laser cutting or rotary cutter. Alternatively, the metal foil fed in constant steps is cut by punching and is temporarily spot-welded onto the substrate member fed in the same manner using the punch as the welding electrode. Such a step provides a material to which pieces of metal foil of a required size are temporarily fastened maintaining a highly precise pitch. Thereafter, the constant-load control and the constant-elongation control are carried out in cascade in the steps of pressing and rolling such that the material has a predetermined thickness. Furthermore, a desired position is detected from the pitch after rolling or from a predetermined reference point to obtain the above desired load. Thus, the thickness of the material is highly precisely controlled to obtain a spot cladding member having a highly precise pitch and size.

Abstract:
For providing an electric connection box including a metal core board, which can limit increase of a size thereof and be prevented from bending along the slit, the electric connection box 10 includes a metal core board 1, in which a plurality of core metal plates 21, 22 is laminated and insulation resin is filled between each of the plurality of core metal plates 21, 22. The plurality of core metal plates 21, 22 are provide with slits 3A, 3B to divide the core metal plates 21, 22 to a plurality of separate plates 21a, 21b, 22a, 22b and be filled with insulation resin. The slits 3A, 3B is formed not to overlap each other on the same one line when viewing in a vertical direction about the metal core board 1. The electric connection box 10 distributes electric power inputted from a plurality of power systems to each separate plates 21a, 21b, 22a, 22b.
Abstract:
A liquid pressure transfer method for transferring a printing pattern on a transfer film to an objective article, by floating the transfer film having the printing pattern on the upper surface thereof on a liquid level inside a transfer tank, and immersing the transfer film with the objective article into a liquid inside the transfer tank by utilizing a liquid pressure, wherein an ink set containing at least printing inks of blue, yellow and red is used for printing the transfer film. Each color printing ink comprises a pigment containing a resin component and a coloring pigment. The coloring pigment is Phthalocyanine Blue for the blue ink, Isoindolenone Yellow for the yellow ink and Quinacridone Red for the red ink. The ink set can further contain a white ink and/or a black ink, and titanium white is used as the coloring pigment of the white ink, and carbon black for the coloring pigment ofthe black ink. Since these printing inks have excellent weatherability, the liquid pressure transfer article having the transfer pattern using these printing inks has excellent balance of color tone, excellent weatherability and long product life.

Abstract:
A rack guide (G) has on its outer periphery a pair of semi- circular tube surfaces (54) and a pair of flat surfaces (55) positioned between the pair of semi-circular tube surfaces (54). The rack guide (G) also has, on its axially one end side, a concave surface (51) positioned inward relative to the pair of semi-circular tube surface (54) and the pair of flat surfaces (55). The rack guide (G) further has, on its axially the other end side, a rack guide base body (50) having a circular tube surface (52) positioned inward relative to the pair of semi-circular tube surface (54) and the pair of flat surfaces (55), and a slide element (60) fixed to the rack guide base body (50).
Abstract:
An exchange (3) has a call charging control section (6) which monitors the numbers of calls of transmission-only portable telephone sets (1B) for every terminal identification number whenever a telephone set (1B) makes a call, and rejects a call from the telephone set (1B) corresponding to the terminal identification number when the number of calls of a terminal identification number reaches a prescribed value, as a transmission-only portable telephone set management function in addition to the charging function. If the system operator inputs a permit from a prescribed operating terminal (7), etc., the section (6) again accepts a call from the telephone set (1B) corresponding to the terminal identification number from which the call has been rejected once.
Abstract:
A method of and device for working a clad plate to be used as a lead frame for a flat package type integrated circuit. A metallic foil in a specified size is overlaid on a material in the shape of a strip at a specified position, pressed and rolled into a continuous clad material, and, when boring reference holes in the clad material, exact positioning is performed between not only reference holes but also the metallic foil formed on the clad plate beforehand and the reference holes, whereby, even when pitches between a plurality of reference holes in the clad plate are different from each other, continuous press work using a metallic die and depending on these reference holes is performed.
