Title: Activated carbon cartridge and device for recovering solvent
Inventor: NAKANISHI MOTOYASU
IPC: B01D53/04
Filed: 1995-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent pressure loss and solvent loss caused by gas leakage even in the case of using a miniatured and simple fan and to fully display the original performance even in a small amount of activated carbon by laminating the layer of a fibrous body and the layer of activated carbon in a bag body in which the bottom is air-permeable and the circumferential wall is air- nonpermeable. SOLUTION: In the case of laminating the layers of a fibrous body 2 and layers of activated carbon 3 in a bag body 1, material formed into a nonwoven fabric sheet-shape by disentangling coconut fiber is used as the fibrous body 2. In such a way, when the layers of the fibrous body 2 and the layers of activated carbon 3 are filled so as to be laminated, activated carbon is prevented from being crammed from the upper part by its own weight. Since the layers of the fibrous body 2 receive the weight of activated carbon 3 existing thereon and also are not so compressed, the layers of the fibrous body 2 become stepwise air reservoirs. When a solvent is successively permeated through the layers of activated carbon 3, its breathable resistance is reduced and contact with activated carbon 3 is surely performed.

Title: Laser welding method
Inventor: SHINTANI HIDETSUGU
IPC: B23K26/32
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To secure sufficient penetration and to improve welding efficiency, in welding a material having a high reflectance against a laser beam such as aluminum, copper, gold or silver, by performing laser welding with a sheet of low reflectance material placed on the welding position. SOLUTION: On the welding position of a material W with a high laser beam reflectance, a sheet 16 of about 5-50μm of a low reflectance material is placed such as a ferroalloy like SUS304 stainless steal or phosphor bronze, and is irradiated with a laser beam LB, so that welding is performed for the material W with a high laser beam reflectance. Since the laser beam LB is thereby efficiently absorbed by the sheet 16, the heat energy contained in the laser beam LB can be efficiently imparted to a member W to be welded. In addition, since the laser beam LB can be emitted vertically to the member W, the irradiation can be carried out with a power density secured, thereby enabling the wedding efficiency to be increased.
