摘要： The present invention relates to a dispersion-shifted optical fiber comprising a structure for reducing optical loss and restraining nonlinear phenomena from occurring. In order to restrain the nonlinear phenomena from occurring, this dispersion-shifted optical fiber has an effective area of 70 &mgr;m2 or more with respect to light whose center wavelength falls within the range of 1500 to 1600 nm, and the peak position where optical power of the light in a fundamental mode is maximized is radially shifted from a center of a core region by a predetermined distance. Also, in this dispersion-shifted optical fiber, optical power at a position radially separated from the peak position by a distance which is five times the center wavelength of the light becomes {fraction (1/100)} or less of the optical power at the peak position. As a consequence of this structure, bending loss can effectively be reduced.

摘要： A device management system is provided which is used in a client/server architecture system, enabling safe sharing of a device without compromising user convenience. In a case where the device which is connected to a client is accessed from a server, in order that the device connected to the client can be used from the server by merely connecting the device to the client without performing another operation, a filter is provided on the client side, and a pseudo bus driver is provided on the server side. The filter in the client exclusively controls client operations to the device and server operations to the device. The pseudo bus driver virtually functions as a device driver between a communication unit for the client and the application in the server.

摘要： An oscillator and a radar apparatus that includes a resonator electro-magnetically connected to a micro strip line and a rotor connected to the resonator by capacitance. The bottom surface of the rotor has a changing height in the circumferential direction of the rotor. As the rotor is rotated, an actual oscillation frequency is recognized from the rotating angle of the rotor when an output of a detector has a peak. A modulation voltage supplied to a VCO is corrected in accordance with the result.

摘要： The present invention provides a line transition and a method for manufacturing the same. The line transition is constructed such that a planar circuit can be arranged in the direction parallel to the propagation direction of electromagnetic waves propagating through a solid waveguide, the coupling characteristics of the solid waveguide with the planar circuit formed on a dielectric substrate are not influenced by the assembly precision of the waveguide and the circuit, and the line transition characteristics are not affected by a variation in manufacturing the dielectric substrate. Notches are formed at the edges of the dielectric substrate in the vicinities of coupled-line pattern segments formed on a dielectric substrate. The notches are formed by punching through holes in a ceramic green sheet serving as a motherboard, firing the motherboard, and cutting the motherboard using dicing lines passing through the through holes.
