Title: Multiple blade centrifugal fan
Inventor: KAWAGUCHI HIDEKI
IPC: F04D29/30
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce interference noise of a casing tongue part by inclining a blade in relation to the rotary shaft of an impeller. SOLUTION: Air sucked into a casing 6 flows in an inter-blade flow passage 5 passing the center opening part of an impeller 4. Air injected from the outer rim of the inter-blade flow passage 5 toward an outer diameter collides with the tongue part 6c of the casing 6 so as to generate interference noise. A blade 3 is inclined in relation to the rotary shaft X of the impeller 4, and the inter-blade flow passage 5 is inclined in relation to the rotary shaft X of the impeller 4. Air one ejected from one end part 5a of the height direction of the inter-blade flow passage 5 and the other ejected end part 5b of the height direction of the inter-blade flow passage 5 are different in time, and they collide with the tongue part 6c of the casing 6.  As a result, a phase difference is generated between interference noise generated by making air ejected from the end part 5a of the inter-blade flow passage 5 collide with the tongue part 6c of the casing 6, and interference noise generated by making air ejected from the end part 5b of the inter-blade flow passage 5 collide with the tongue part 6c of the casing 6. Interference noises whose phase differences are different from each other are interfered each other so as to reduce interference noise of the tongue part 6c of the casing 6.

Title: Automatic document feeder
Inventor: FUJII TAKASHI
IPC: B65H5/06
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain an automatic document feeder which securely prevents the occurrence of an unfed document by providing particular numbers of rollers and pressing members, and giving the document carrying face of each roller a shape like a circular arc. SOLUTION: A sheet feed means is equipped with the rollers 21 disposed in the direction of document width, and the pressing members 23a, disposed on the same line in the direction of the disposal of the rollers 21, which press parts of each document, which are outside both edges of each roller 21, toward the roller. Because the document carrying face of each roller 21 is in the shape of a circular arc, the area of the contact between the roller 21 and the document P can be increased. Therefore, a document carrying force can be increased without increasing the pressing force of a partition plate 23, and the document can be prevented from being damaged, soiled, or unfed in carrying.  Also, in the case where the number of documents to be carried is small and they bend due to stiffness, etc., a decrease in carrying force is prevented and the occurrence of an unfed document is prevented, because the document comes into contact with the arc-shaped face of each roller 21.
