Title: Tape-like component housing
Inventor: TAKAHASHI MITSUO
IPC: B65D73/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To efficiently determine whether a component exists with a simple structure by sealing recesses for receiving the component formed on one of faces of a component housing at predetermined pitches with a sealing means and by coloring at least a bottom of the recess in the component housing in a different color from that of the component. SOLUTION: A top cover tape 31 of the tape-like component housing 30 is formed of a relatively high transparent resin material, while a bottom face part 32A forming a recess 33 together with each bore 2A among a bottom cover tape 32 is colored in a predetermined color. By selecting a color applied to the bottom part 32A of the bottom cover tape 32 to be clearly different from that of an electronic component 5, an operator can easily determine whether the electronic component 5 has been received in the recess 33 only by visual observation. Further by selecting the color applied to the bottom part 32A to be a complementary color to that of the electronic component 5, the operator can further reliably determine whether the electronic component 5 exists.

Title: Connection structure, manufacture thereof, and mounting structure
Inventor: TAKEZAWA HIROTERU
IPC: H01L23/12
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of ion migration for reliable connection by, related to a connection structure comprising an electrode and a conductive bond so laminated on the upper surface on the electrode as electrically contacts the electrode, allowing the contact area between the conductive bond and the electrode to be smaller than the area of the upper surface of the electrode. SOLUTION: An electrode 2 and a conductive bond 1 comprising silver are electrically connected, with no conductive bond 1 overflowing outside the electrode 2. For the electrode 2, a metal that is hard to cause ion migration such as Cu, Au, Pd, Ni, Ag-Pd, Pt, etc., are used. When a voltage is applied between the electrode 2 and an adjoining electrode under high-temperature and high- humidity, the voltage is applied only to the nearest pats between adjoining electrodes. Since the conductive bond 1 does not overflow the electrode 2, the material at the nearest part is to be such electrode 2 as hard to cause ion migration, resulting in ion migration hard to occur between adjoining electrodes. Thus, excellent insulation reliability is provided.

Abstract: PURPOSE:To deflect the annular flow coming out of a blow-off port in wide angles by installing an annular blow-off port formed of two thin nozzles and also installing a curved guide wall down-stream from those nozzles and controlling the adhesion effect by the control plates installed at the annular blow-off port. CONSTITUTION:When a control shaft 14 is shifted upward, the stream A which flows into a cylindrical feeding chamber 3 is divided into the outside flow B and the inside flow C by controlling plates 11a-11d. Though the outside flow B tends to be directed inwardly by the back pressure effect in a range F, in the feeding chamber 3, said flow is attached onto a guide wall 7, as control plates are titled outwardly. On the other hand, the flow C is directed outwardly by the back pressure effect in a range C, in the feeding chamber 3. At this time, as the control plates are titled outwardly, outward deflection of the flow C is not obstructed markedly. Accordingly, the combined flow D forms a deflected flow in spread form.
