Title: Needle head fastening seat for safe syringe
Inventor: LUO BI-ZHANG
IPC: A61M5/32
Filed: 2003-02-14
Abstract: A needle head fastening seat for a safe syringe is a fastening seat formed of a needle head seat and a buckle seat and housed in an annular groove on the front end of a syringe for insertion fastening of a needle head, in which the needle head seat has a tolerance groove for the upper/lower step ring in order to endowing the needle head seat with a suitable elasticity. The needle head seat and the buckle seat have a pressing and buckling relationship between themselves so that after an injection operation of the safe syringe, the buckle head at the end of the push rod and the fastening seat complete a buckling operation. Then, the buckling force is larger than the buckling restriction between the elastic sheet of the needle head seat and the annular groove, such that a retraction operation of the push rod will also pull back the fastening seat and the needle head for them to be housed in the injection cylinder. As a result, the needle head will not be exposed on the tip of the injection cylinder and cause a safety concern.

Title: Dicing tape
Inventor: ISHIKAWA SEIJI
IPC: C09J183/10
Filed: 2003-07-22
Abstract: Dicing tape comprises a tackifiable adhesive layer which is composed mainly of a polyimide and has a peel strength of 0.02 N/mm (20 gf/cm) or greater as the adhesive strength at near room temperature (20-50 DEG C) and a cured peel strength of 0.3 N/mm (300 gf/cm) or greater. The tape exhibits adhesive strength with silicon wafers sufficiently high to allow dicing at near room temperature, and also exhibits high adhesive strength with circuit boards after curing, in light of the processing disadvantages of polyimide -based dicing tape resulting from its low tacky strength (initial adhesive strength) at low temperatures of around room temperature, which requires a higher ambient temperature to increase the adhesive force and thus necessitates supplementary heating equipment.
