Title: Chip fuse element
Inventor: FUJIMORI HIROYUKI
IPC: H01H85/046
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent a glass layer from scattering due to excess abnormal electric current by successively forming a fuse conductor thin film, a low melting point glass film, a silicone elastic coating film, and an overcoat resin film on a glass glaze layer on an insulating substrate. SOLUTION: After a glass glaze layer 11 is formed on the surface of an insulating substrate 1 of, for example, an alumina ceramic, an approximately H-shaped fuse conductor thin film 3 of such as Au, Ag, Al, is formed by a photolithographic technique. Terminal electrodes 2a, 2b are formed by overlaying in both end parts of the film 3 and at the same time a low melting point glass film 5 is formed on a melting and depositing part. A silicone elastic coating film 6 is so formed as to completely cover the film 5 and further an overcoat resin film 7 is formed on the film 6. Consequently, even if excess abnormal electric current flows in the resultant fuse chip element and the film 3 is exploded, the glass film 5 is moderated by a buffer reaction of the coating film 6 and prevented from being blasted off and scattered to outside.

Abstract: PURPOSE:To obtain the in-nasal cavity fine powder atomizer of a concise constitution without using a movable type switching valve at all by forming integrally a ventilation means and suction means by a filter which powder is not allowed to pass through and gas can pass through. CONSTITUTION:A capsule C containing powder is set to a powder containing chamber 2 of an atomizer body 1, a cap 5 is fitted and installed in the outside of a front chamber 2a and a long needle 5a is pierced through the capsules C and both ends are opened. When a pump chamber 4 is pressed, air in the pump chamber flows into a ventilation chamber 3 from a filter 6. In this case, a pressure air current flows into the powder containing chamber 2, blows through from an open hole of the rear end of the capsule C to an open hole of the front end, blows out from under a blowout hole of the front end of the body 1, while rolling in powder in the capsule, and powder atomization is realized. When pressure of a compressed pump chamber 4 is stopped, air flows in from a suction hole and a blowout hole and goes to the filter 6 side together with powder, but powder contained there in is obstructed and only air passes through the filter 6 and flows into the pump chamber 4. When the pump chamber 4 is compressed again, atomization is repeated.
