Title: Printed wiring board
Inventor: USAMI KAZUO
IPC: H05K3/34
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To allow cracks to hardly appear in a solder connection due to thermal stress caused at the time of flow-soldering of insertion mounted components, by applying heat-resisting resin to form a heat-resisting resin film on a soldered face of a surface solder mounted component mounting area. SOLUTION: A heat-resisting resin film 2 is formed on rear faces (soldered faces) of a QFP(quad flat package) 3 and a BGA(ball (grid array) 4 mounting areas 31, 41 of a printed wiring board 1. For the heat-resisting resin film 2, resin which has a relatively low heat conductivity and is bearable to a melted solder temperature and has no bad influence on a conductive pattern of the printed wiring board 1 even if it is airtightly adhered to the conductor pattern for a long time is applied onto the printed wiring board 1 by screen printing. Modified vinyl resin, heat-resisting silicon resin, or the like is good for such resin. It is preferred that the resin is applied in a region 2-5 mm wider on all sides than the component mounting areas 31, 41. After that, the applied resin is hardened to form the heat-resisting resin film 2.

IPC: H01M2/12
Filed: 1990-02-26
Abstract: PURPOSE:To prevent a battery from breakdown by installing an isolating member between a spiral electrode and a sealant, hindering a molten separator from moving to a safety valve, supplying only the gas to the safety valve, and thereby ensuring normal valve operation. CONSTITUTION:A spiral electrode 1 is accommodated in an armor can 2, and its opening is blocked by a sealing member 3, which is fitted with a safety valve. A valve plate 9 is pushed up with raised internal pressure of a battery concerned, and a hole 12 is opened, and a spring 10 presses this valve plate 9 to the hole 12 at normal times. An isolating member 4 admits passage of the gas generated by this spiral electrode 1 and checks passage of the molten resin of separator 7 perfectly. The isolating member 4 is made for ex. of graphite cloth of carbon fiber. In the case a porous inorganic substance is used, it is recommended to lessen its porosity below 98% so as to decrease the permeability for the molten resin of separator 7. This constitution precludes effectively the sealed type battery from breakdown.

Title: Seal of dust cover for ball joint
Inventor: YAO KYOICHI
IPC: F16J15/52
Filed: 1989-02-28
Abstract: PURPOSE:To prevent lowering of sealing capacity even at the time of exchange of a connecting rod so as to maintain the sealing capacity for a long time by providing a first seal member made of a rubbery, elastic body in a space between a first collar part and a second collar part, so that, when the connecting rod is exchanged, the first seal member makes the second, annular collar move upward. CONSTITUTION:When a connecting rod 31 is exchanged, a nut 32 is released from the state of the connecting rod 31 engaged in place, and then the connecting rod 31 is removed. Then, a second annular collar 15 is moved upward relative to a first annular collar 11, owing to the restoring force of a first seal member 19, which has been deformed by the pushing pressure of the connecting rod 31. Next, a new connecting rod 31' is inserted into the tapered part 34 of the handle of a ball stud and fixed by means of the nut 32. Accordingly, even when the diameter of a through hole 25' of the connecting rod 31' after exchange is smaller within a tolerance than that of a through hole 25 of the connecting rod 31 before exchange, no gap can be formed between the connecting rod 31' and a seal member 27, even if the connecting rod 31' after exchange cannot go into the handle 3 up to the former position of the connecting rod 31 before the exchange, because the collar 15 is moved upward in advance.
