摘要： A user terminal for wireless communication with a remote access point can include a mapping module, a delay module, a transmit module, and a directional antenna. The mapping module can be used to map one or more input data bits to an uplink symbol. The delay module can be used to apply a delay to the uplink symbol. The transmit module can be used to modulate the delayed symbol into a frequency channel. The directional antenna can be oriented along a dominant path to the access point, and the antenna is used to transmit the modulated symbol to the access point. The delay is chosen such that the transmitted symbol arrives at the access point simultaneously with a another symbol that is modulated into the frequency channel and transmitted by another user terminal.

摘要： An OFDM wireless communication system with an access point and a plurality of remote user terminals estimates an uplink channel. The access point receives training symbols transmitted by the user terminals. Each training symbol includes pilot symbols associated with phase offset estimation OFDM sub-carriers. The phase offset estimation sub-carriers include subsets of sub-carriers associated with each respective user terminals. Each subset is used exclusively by the associated user terminal during channel estimation. The channel estimation sub-carriers are used by all user terminals. For each terminal the access point estimates symbol-specific phase offsets specific to the user terminal using the received pilot symbols associated with the user specific subset of the phase offset estimation sub-carriers. The access point also estimates the uplink channel using the user-terminal-symbol-specific phase offset estimates and the received symbols.

摘要： A force-feedback multidirectional input device includes a slider slidably supported by a support base and an operation knob joined to the slider. In a sliding operation, the slider operates in conjunction with actuating members included in a force-feedback unit. Therefore, a sense of force based on the sliding is fed back to the operation knob. Furthermore, the slider is elastically urged by coil springs toward an inner bottom surface of a housing space defined in the support base. In a depressing operation, the operation knob presses the support base downward against the urging force of coil springs. Therefore, a vertically movable member joined to the support base is moved downward along guide portions (convex rails and concave grooves). Thus, a push switch provided on a pedestal (circuit board) is pressed and activated by the vertically movable member.

摘要： A fuel injection valve can be provided, with which temperature at needle valve seating position can be decreased and carburization of fuel and deposition of the carbide near the needle valve seating position can be prevented resulting in stable normal fuel injection control, and which is applicable to small and middle and also to large engines, particularly gas engines. The fuel injection valve is composed such that distance (A) from a seating face of the nozzle in the nozzle supporting body to a seating position of the needle valve in the nozzle is determined to be smaller than distance (B) from the nozzle seating face in the nozzle supporting body to the lower end of clearance between a nozzle insertion hole of the nozzle supporting body and a fitting part of the nozzle inserted into the nozzle insertion hole, thereby suppressing heat flow to the needle valve seating position.

摘要： An electrophotographic photoreceptor which can respond to a reduction in diameter of photoreceptor and a process having high circumferential speed, due to the demand in the miniaturization and increase in the speed of copiers and printers. The photoreceptor has high sensitivity in long-wavelength region, and is free from deterioration of electric characteristics even after repeated use, and is highly stable. The electrophotographic photoreceptor has a conductive support member and a photosensitive layer laminated thereon, which includes at least a charge-generating agent, a charge-transfer agent, and a binder resin. The charge-generating agent is oxytitanium phthalocyanine, which has a Bragg angle (2θ±0.2°) providing a maximum peak at 27.2° in the X-ray diffraction spectra using CuKα as a radiation source.
