Title: Enclosed type compressor
Inventor: SASANO HIROSHI
IPC: F04B39/02
Filed: 1990-11-05
Abstract: PURPOSE:To make the main shaft and the eccentric shaft diameters of a crankshaft smaller and supply oil to respective sliding parts by satisfying a prescribed formula of a communicating hole in a centrifugal pump formed at the crankshaft to the main shaft of the crankshaft. CONSTITUTION:Diameters of the main shaft 4a and the eccentric shaft 4b of a crankshaft 4 are relatively smaller than conventional ones. A feed oil port 8 which fixes a feed oil pipe 7 is the same as conventional one, and an eccentric amount S to the main shaft 4a of the crankshaft 4 is the same. In a communicating hole 6, an intersection point of the centroid A of the feed oil port 8 and the top edge surface 4c of the crankshaft 4 is taken as a starting point, and the communicating hole 6 is machined at an oblique position of angle theta which satisfies a formula I (where, D: main shaft outer diameter of crankshaft, H: eccentric part length of crankshaft, theta: inclination angle of communicating hole, and (d) : communicating hole diameter). With this constitution, it is thus possible to make the diameter of the crankshaft 4 smaller and supply oil 9 to respective sliding parts in the centrifugal pump 5 through the oblique communicating hole 6.

Title: Substrate treating device
Inventor: MAEKAWA NAOTADA
IPC: B08B3/10
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To provide an immersion type substrate treating device capable of well subjecting a substrate surface to treatment over the entire surface. SOLUTION: A lifter 10 receives the plural untreated substrates W on the outside above a treating vessel 5 and descends to hand over the substrates W to an in-vessel holder 14. The portions held in contact with the substrates W are thereby alternated from longitudinally grooves which are the substrate holding part of the lifter 10 to the in-vessel holder 14. The main treatment process by a treating liquid 6 progresses while the substrates W are held by the in-vessel holder 14 and during this time, the substrate holding parts of the lifter 10 are evacuated below the substrates W. The portions held by the substrate holding parts of the lifter 10 among the peripheral edges of the substrates W and the portions W14 held by the in-vessel holder 14 are separate portions.  Such substrate portions where the contact with the fresh treating liquid is hindered are, therefore, eliminated over the entire part of a series of the process and the good treatment may be executed over the entire surface of the substrates surfaces.
