Title: Temporary wet strength paper
Inventor: SMITH DAVID JAY
IPC: D21H17/29
Filed: 1997-07-22
Granted: 1999-12-11
Abstract: The present invention relates to paper products having temporary wet strength. The paper products contain cellulosic fibers that are treated with a polyaldehyde polymer having free aldehyde groups and a water soluble polyhydroxy polymer. The initial wet strength obtained with the combined use of these materials is significantly greater than that obtained by use of either the polyaldehyde or polyhydroxy polymer alone. At the same time, the wet strength decays at a rate that is rapid enough to enable the paper product to be flushed under conditions of normal use. Preferred polyaldehydes include cationic, aldehyde functionalized starches and cationic, aldehyde functionalized polyacrylamides. Preferred polyhydroxy polymers are polysaccharides having cis-hydroxyl groups in at least a portion of the main polymeric chain (i.e., polymer backbone). Preferred polysaccharides include those derived from one or more sugars selected from mannose, galactose, allose, altrose, gulose, talose, ribose, and lyxose. Economically preferred polysaccharides are guar gum, locust bean gum and ionic derivatives thereof. The polysaccharide is preferably a neutral polysaccharide or a charge balanced mixture of polysaccharides.

Title: Space saving laser programmable fuse layout
IPC: H01L23/525
Filed: 1997-09-20
Granted: 2000-07-01
Abstract: A compact laser programmable fuse structure has a central line and two sets of fuses extending from opposite sides of the central line. An opening through a passivation layer exposes the fuses and overlies the central line. In one embodiment, the opening also exposes the portions of the ecntral line. The central line is made of fuse material or another material for which the opening does not create reliability problems. In one embodiment of the invention, the central line and the fuses are parts of a single contiguous region of polysilicon. This fuse structure has a length that is about half the length of conventional fuse structure having the same number of fuses because two fuses, one on either side of the central line, fit within a length used for a single fuse in conventional fuse structures.

Title: Method for shifting a bicycle transmission
Inventor: MIRURA YOSHIKI
IPC: B62M9/132
Filed: 1997-10-08
Granted: 1999-02-11
Abstract: A method of shifting a bicycle transmission includes the step of calculating, by a computer, a past period of a wheel revolution. The computer may then calculate a current virtual period of the wheel revolution from the past period. The bicycle transmission is then shifted at a time calculated by the computer within the virtual period. In another embodiment of the present invention, a virtual velocity may be calculated from the past period, and the bicycle transmission may be shifted at the virtual velocity. If desired, the computer may calculate a past velocity from the past period, and the virtual velocity may be calculated from the past velocity. To alleviate stress on the transmission, the bicycle transmission may be shifted when the virtual velocity is less than the past velocity (i.e., during deceleration). Also, the virtual velocity may be set for a smooth transmission from one gear to another.

Filed: 1999-07-30
Granted: 2001-04-21
Abstract: A copyright protection system for protecting content wherein a receiver dependent ticket is calculated at a source device by combining a receiver dependent identifier with a ticket. The receiver dependent identifier is transmitted from the receiver to the source device prior to the source device transmitting watermarked content to the receiver. The receiver dependent identifier is also stored at the receiver. Thereafter, the source device transmits, to the receiver, watermarked content, the ticket, and the receiver dependent ticket. At the receiver, the stored receiver dependent identifier is combined with the ticket in the same way that the receiver dependent identifier is combined with the ticket at the source device. A result of the combination is compared to the receiver dependent ticket and if the result equals the receiver dependent ticket, then the watermark and ticket may be compared in the usual way to determine the copy protection status of the copy protected content.
