Title: Packing material and packing material machining apparatus
Inventor: KAJIWARA SUNAO
IPC: B65D81/03
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To provide packing materials made of a thin sheet material, capable of preventing a packed article from being marred, dented and deformed, by carrying out a simple machining operation for abutting parts of the packing materials, which abut against the article. SOLUTION: A plurality of comb-like bent pieces cut in a predetermined length at fixed intervals are provided at abutting parts of packing materials 54a, 54b, which abut against an article to be packed. Further, with respect to an article which uses a net made of cloth or the like and has a flexible abutting face, a plurality of holes or slits are formed in the abutting parts of the packing materials by carrying out a machining operation, thereby reducing the abutting area of each packing material, so that the abutting parts are deformed and depressed along a shape of the abutting surface of the packed article according to vibrations in transportation or the like. Thus, the vibrations of the article are absorbed, and the abutting area of each packing material is widened to reduce pressure applied to the abutting surface of the article.

Title: Aluminum electrolytic capacitor
Inventor: KUNUGIHARA HIROSHI
IPC: H01G9/12
Filed: 1990-05-29
Abstract: PURPOSE:To prevent gas of driving electrolytic solution from flowing to the outside by providing a space part above an explosion-proof valve provided to a top board part of a metallic case, by providing a first absorbing material to the explosion-proof side positioned inside the space part and by providing a buffer board and a second absorbing material to the outside. CONSTITUTION:Fiberglass, porous hypolymer, etc., are used as first and second absorbing materials 9, 11. When an overvoltage above the rated value is applied to an aluminum electrolytic capacitor, an internal ressure of a metallic case 2 rises, thereby allowing an explosion-proof valve 6 provided to a top board part 2a to start, and driving electrolytic solution in the inside ejects from the explosion-proof valve 6. In the process, gas of driving electrolytic solution is partially absorbed by the first absorbing material 9. Gas of driving electrolytic solution which is not absorbed by the first absorbing material 9 falls on a lower surface of the buffer board 10 having a small hole 10a and most thereof is cooled and liquified, and drops. Since gas of driving electrolytic solution which passes through the small hole 10a of the buffer board 10 is absorbed by the second absorbing material 11 provided outside the buffer board 10, driving electrolytic solution does not leak to the outside.

Abstract: PURPOSE:To obtain a lens-barrel prevented from being easily destructed even if large torque is applied to a distance ring by providing the lens-barrel with plural rotation stopping members integrated with a distance ring and plural rotation stopping member integrated with a fixed frame. CONSTITUTION:When the distance ring 1 is rotated in the clockwise direction, the rotation of the ring 1 is stopped by two positions, i.e. one position consisting of a stopper rib 1a and a stopper part 3a projecting from the fixed frame 3 and the other position consisting of a stopper rib 1b and a stopper 4a and an infinite end is set up. On the other hand, the crossclockwise rotation of the distance ring stops the rotation of the distance ring on two positions, i.e. one position consisting of the stopper rib 1a and the stopper 4a and the other position consisting of the stopper rib 1b and a stopper 4b, and a point-blank end is set up. Since the stopper ribs of the distance ring and the stoppers of the fixed frame are respectively abutted on the two positions, the lens can be prevented from being easily destructed even if large torque is applied to the distance ring.
