Patent JP-H0286538-A (JP)
Title: Roller device
Inventor: USUI KAZUNORI
IPC: B65H27/00
Filed: 1988-09-22
Abstract: PURPOSE:To resolve the generation of wrinkling, snaking, breakdown and discontinued running by forming, on a connecting part in the intermediate between cylindrical parts on the outer circumferential part of a roller, a vertex part lower than a circle with the diameter of the cylindrical part and higher than a straight line connecting between the end parts of the cylindrical parts. CONSTITUTION:A band body is fed in contact to a vertex part 4 between cylindrical parts 2, 2 formed at determined intervals in the circumferential direction. The generation of wrinkling is suppressed by the cylindrical parts 2, and the tension variation given to the band body is reduced by the vertex part 4 to suppress the generation of vibration and breakdown. A rapid bending to the band body can be prevented by forming the part of the ridgeline 5 between the cylindrical part 2 and a connecting part 3 in a curved surface, so that the band body having a low mechanical strength can be also fed without causing a breakdown.

Title: Surface mounting package
Inventor: TACHIKAWA ATSUSHI
IPC: H05K3/34
Filed: 1989-09-11
Abstract: PURPOSE:To easily position a surface mounting package against a substrate by forming at least one tab for positioning on the rear of the package. CONSTITUTION:A square pole-like tab 15 for positioning is formed at the center on the rear of this surface mounting package 14 and a square hole 16 for positioning into which the tab 15 can be inserted tightly is provided at the central part on the upper surface of a substrate 11. When the tab 15 is inserted into the hole 16, the rear surface section of the tip of a lead 13 coming out from the side face of the package 14 comes into contact with a wiring pattern 12 on the substrate 11. Therefore, the lead 13 can be surely brought into contact with the pattern 12 and the time required for positioning the package 14 can be reduced. In addition, since the tab 15 has a square cross section, the tab 15 is tightly fixed to the hole 16, accordingly, the package 14 is fixed to the substrate 11, with no positional deviation between the wiring pattern 12 and lead 13.

Filed: 1989-09-12
Abstract: PURPOSE:To easily hold the temperature of a housing by winding a tube for cooling water around the outer surface of the housing, separating one part of the tube from the housing and providing a radiating part. CONSTITUTION:A tube 20 is wound around the outer surface of a housing 3 to house a positioner 13, which holds a magnetic head 12, and a magnetic recording medium 11. The inside of the tube 20 is filled with cooling water and the cooling water is circulated by a pump 30.

Thus, the cooling water absorbs heat in the housing 3 while flowing the recessed part of a rib 5 and the heat is discharged in the heat discharge part 4. Then, the cooling water flows again in the recessed part of the rib 5 and accordingly, the inside of the housing 3 is kept at the fixed temperature.

Title: Semiconductor integrated circuit
Inventor: KUNO ISAO
IPC: H05K3/34
Filed: 1984-11-09
Abstract: PURPOSE:To enable solder bonding having high quality without lowering the mechanical strength of a terminal by narrowly forming the width of a terminal soldering section for an integrated circuit to a copper foil on a printed substrate. CONSTITUTION:A soldering section 1a for a terminal 1 is shaped in size narrower than the width of the terminal 1. According to such constitution, creamy solder 4 melts and the terminal 1 and a copper foil section 2 are soldered in soldering work, but the width of the soldering section 1a for the terminal 1 is narrowed, thus melting solder into a vessel in the side surface section of the soldering section 1a with the melting of solder 4. Consequently, solder flows into not only the soldering section 1a but also the side surface sections of other elements in the terminal 1, thus resulting in positive soldering.
