Abstract: A signal quality monitoring method which can rapidly identify the location of a failure is disclosed. In a WDM network composed of a plurality of elements, each of the repeaters detects signal transmission quality for a corresponding transmission line based on a section quality check information included in a transmission signal received from the preceding element. After replacing the section quality check information with a new computed section quality check information, the repeater transmits a second transmission signal to a following element. When receiving a quality request from another element, the repeater transmits the signal transmission quality to the element originating the request.

Title: A level regulating and/or vibration dampening device for a snow-removing machine
Inventor: ITO TOMOKI
IPC: F16F9/02
Filed: 2000-07-06
Granted: 2005-01-04
Abstract: In a snow-removing machine, an expandable and contractible regulating mechanism is coupled between a steering handlebar of a machine body including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism is comprised of a cylinder connected to the machine body, a piston which divides the inside of the cylinder into a first chamber and a second chamber, a piston rod coupled to the piston and connected to the drive section, a communication passage permitting communication between the first and second chambers, and an on-off valve for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.

Abstract: Described is a novel family of cell surface serpentine transmembrane antigens.  Two of the proteins in this family are exclusively or predominantly expressed in the prostate, as well as in prostate cancer, and thus members of this family have been termed "STRAP" (Serpentine TRansmembrane Antigens of the Prostate). Four particular human STRAPs are described and characterized herein. The human STRAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STRAP family, STRAP-1, appears to be a type IIIa membrane protein expressed predominantly in prostate cells in normal human tissues. Structurally, STRAP-1 is a 339 amino acid protein characterized by a molecular topology of six transmembrane domains and intracellular N- and C-termini, suggesting that it folds in a "serpentine" manner into three extracellular and two intracellular loops. STRAP-1 protein expression is maintained at high levels across various stages of prostate cancer. Moreover, STRAP-1 is highly over-expressed in certain other human cancers.

Abstract: The inventive mounting device, which is located on a fire arm, has a longitudinal mounting channel (1) on which a mounting base (11) can be placed, said mounting base serving as a device support. The mounting base is only held in place by the pressure of a predetermined spring force instead of being clamped tight in such a way that it cannot be freed without releasing the clamping device, as is customary. Therefore, it is also possible to produce the longitudinal mounting channel (1) from a plastic that can only be subjected to a limited compressive load per unit area.
