Inventor: HAYASHI SHIRO
IPC: B01D53/81
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a filter element having a sufficiently high deodorizing function and in which activated carbon and an activated inorganic adsorbent are kept in non-contact state, deterioration of functions of both materials is prevented, and both materials are made hardly peeled by forming an activated carbon layer in one face side of a fiber sheet and an activated inorganic adsorbent layer in the other face side. SOLUTION: In a deodorizing filter element 11, an activated carbon layer 13 is formed on one surface side of a fibrous sheet 2 such as nonwoven fabric by sticking an activated carbon 15 to the surface of component fibers or inter- fibers of the fibrous sheet 12. Moreover, an activated inorganic adsorbent layer 14 is formed on the other surface side of the fibrous sheet 12 by sticking an activated inorganic adsorbent 16 of such as zeolites to the surface of the component fibers or interlayers of component fibers. The activated carbon 15 and the activated inorganic adsorbent 16 may be stuck to the fibrous sheet 12 through a binder. Consequently, since both materials are kept in a non-contact state, the functions of both materials are not deteriorated and malodor which can not be adsorbed and removed only by activated carbon 15 can be removed.

Title: Enclosed type compressor
Inventor: MURATA MITSURU
IPC: F04B39/02
Filed: 1979-07-09
Abstract: PURPOSE: To increase the power to supply oil without lowering the bending strength of shaft by a system in which a spiral wire fixed in the longitudinal hole of a shaft is turned by an oil supply pump inside an enclosed type compressor and then lubricating oil is pushed up by its feeding action to supply oil.  
     CONSTITUTION: The coil 22 formed by winding a wire spirally into an almost cylindrical shape is pressed into the longitudinal hole 14 of the shaft 4 or fixed with a slight clearance in it. When the shaft 4 rotates, the lubricating oil 12 pushed up by the curved portion 13' of the piece 13 collides against the upper surface 22' of the coil 22, whereupon the lubricating oil 12 is pushed up because the coil 22 is wound in such a direction that the components of collison force are produced upwardly. And, oil is supplied to the clearances 19W21 through the horizontal holes 16W18. Because the upward components of collision force can be increased by making the sprial pitches of the coil 22 smaller, the inside diameter of the longitudinal hole 14 is enlarged and the amount of oil to be supplied is increased without lowering the bending strength of the shaft 4.
