摘要:
An aspect of the invention is an information terminal device includes a widget management unit for managing execution of a widget being a monofunctional program for performing display on the display part of a display device. The widget management unit includes a policy determination unit for determining the operation policy, including operation restriction and priority, concerning a display state at the display device in the widget, and a reliability determining unit for determining the reliability representing the reliability of the widget in the widget. When the state of the movement calculated by a navigation unit becomes a preset state, the widget management unit regulates the display state of the widget according to the operation restriction and the reliability, and performs display, while preferentially displaying guidance state and positional information calculated by the navigation unit.

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.

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.

The present invention relates to a compact dispersion compensator and the like. The dispersion compensator comprises a housing and an optical fiber coil. The optical fiber coil has a coiled part constituted by a dispersion-compensating optical fiber wound like a coil while being in a bundle state with its winding distortion substantially eliminated. The housing is filled with a resin surrounding the coiled part of the optical fiber coil, whereas the coiled part is held by the resin. By this structure, the dispersion compensator can realize a further compactness.

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.

The optical fiber coil has a coiled part constituted by a dispersion-compensating optical fiber wound like a coil while being in a bundle state with its winding distortion substantially eliminated. The housing is filled with a resin surrounding the coiled part of the optical fiber coil, whereas the coiled part is held by the resin. The dispersion-compensating optical fiber constituting the optical fiber coil has a chromatic dispersion of −140 ps/nm/km or less at a wavelength of 1.55 μm, whereas the housing has a volume of 500 cm3 or less. This configuration allows the dispersion compensator to attain an accumulated chromatic dispersion of −1200 ps/nm/km or more but less than −600 ps/nm at a wavelength of 1.55 μm.

An optical fiber is formed for use in optical communications systems capable of transmitting and receiving a large volume of information. The optical fiber has a chromatic dispersion of at least 4 ps/nm/km and at most 15 ps/nm/km at a wavelength of 1,550 nm, a transmission loss of at most 0.190 dB/km at a wavelength of 1,530 to 1,570 nm, and an effective cutoff wavelength measured by the 2-meter method of 1610 nm or more. An optical transmission line and an optical communications system are structured by using the foregoing optical fiber.
摘要:
A random seed scramble for preventing the deterioration of a medium is applied to the next generation optical disk. A seed is stored to a BIS area. ID or an EDC is checked to hold interchangeability before and after scramble release. When no error is generated in data before the scramble release, it is recognized as an unscrambled disk. In contrast to this, when no error is generated in data after the scramble release, it is recognized as a scrambled disk. An information storing area showing an area to be rewritten by performing the scramble and an area to be rewritten without performing the scramble is arranged.
