Title: Signal transmission fuse and method of making the same
Inventor: GLADDEN ERNEST L
IPC: C06C5/04
Filed: 1998-08-25
Abstract: A signal transmission fuse is made of a tube (36) which encases a support tape (14) having a reactive coating (18') which is adhered to one side of the tape by a binder. A method of making the signal transmission fuse includes depositing on the support tape (14) a reactive paint (18) including a binder, which paint dries to form a reactive coating (18'). The coated support tape (14') is then folded, i.e., formed into a channel configuration, to provide an inner concave side of the tape on which the reactive coating (18') has been disposed. The coated support tape is then enclosed, e.g., within an extruded plastic tube (36). One side of the support tape may be made of a first material (14a) to which the reactive coating adheres, and a second side may be made of a second material (14b) which bonds or adheres to the inner surface (36a) of the plastic tube (36) enclosing the coated support tape (14'). The binder causes even high loadings of the reactive coating (18') to adhere to the coated support tape (14') to prevent reactive material migration. The support tape also shields the reactive material from the hot, freshly extruded surrounding plastic tube (36) during manufacture.

Title: Radio communication apparatus and transmission antenna changing method
Inventor: HIRAMATSU KATSUHIKO
IPC: H04B7/06
Filed: 1999-11-16
Abstract: A decision circuit (213) of a mobile station measures the number of passes of a down line; and, if the number of passes is smaller than a threshold value, it decides that an antenna switching operation must be performed, and otherwise decides that an antenna switching operation need not be performed. A  multiplexing-circuit (214) multiplexes a control signal carrying the decision result of the circuit (213) with transmission data for transmitting. A base station separates a control signal from a reception signal and determines whether or not an antenna switching operation should be performed according to the descriptions of the control signal, thereby making it possible to perform a transmission antenna switching operation only when a transmission antenna switching can improve a reception quality and to minimize a transmission antenna switching requirement.

Inventor: NOVOSEL DAMIR
IPC: H02H7/26
Filed: 1999-01-25
Abstract: An adaptive distance relaying system (1) provides improved performance for parallel circuit distance protection. The system utilizes the parallel circuit's current, when available, in conjunction with measurements of voltage and current on the protected line to compensate for the zero sequence current mutual coupling effect. The sequence current ratio (zero or negative sequence) is used to avoid incorrect compensation for relays on the healthy circuit. If the parallel circuit current is not available and the line operating status is, the best zero sequence current compensation factors are selected accordingly as a next level adaptation. If both the parallel circuit current and line operating status are unavailable, a fallback scheme that offers better results than classical distance protection schemes is employed.
