Title: Sheet feeder
Inventor: SHIGE DAISUKE
IPC: B65H3/06
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a sheet feeder capable of reliably separating and feeding recording sheets one by one. SOLUTION: The mounting angle of a driven gear 79 with respect to a rotary shaft 75 is changed so that the mounting angle of a semicircular roller 74 with respect to the rotary shaft 75 varies. More specifically, the orientation of a D-shaped cut 79e of the driven gear 79 for fixing the rotary shaft 75 is changed, and thereby the semicircular roller 74 is installed while being turned counterclockwise. This enables a drive gear 78 and the driven gear 79 to mesh with each other before the semicircular roller 74 abuts on the uppermost recording sheet 71 received in a recording sheet cassette 70. The semicircular roller 74 can therefore reliably separate and feed the recording sheets 71 one by one.

Filed: 2001-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of forming compound thin films through atomic layer deposition using high-k dielectric Group VB species. SOLUTION: A substrate is placed in a reaction chamber. A first reactant gas of a Group VB element is injected into the reaction chamber, where it is chemisorbed as an atomic layer on the substrate surface. A second reactant gas, when it is injected into the reaction chamber, flows over the atomic layer of the first reactant gas and forms an atomic layer on the atomic layer of the first reactant gas. This process can be repeated, alternately subjecting the surface to the first reactant gas and the second reactant gas, until the compound thin film reaches the desired thickness. A purge gas is injected into the reaction chamber between two successive reactant gas injections to purge the chamber of any excess, that is unreacted reactant gas.
