A spoke wheel includes a light alloy rim, a hub, and a plurality of wire spokes connecting the rim with the hub. The rim includes mounting flanges provided at asymmetrical positions with respect to a widthwise center of the rim and is connected with the hub by assembling the spokes to the mounting flanges. The spokes are disposed by being offset to the widthwise center of the rim.

Spoke wheel

A work vehicle () includes an engine (), a cooling device (), first and second hoses (), first and second flanges (), and a third flange (). The third flange () is arranged to overlap with the first and second flanges () by extending in a region R sandwiched between the first flange () and the second flange (). Accordingly, there can be obtained a work vehicle () that can have rain water intruding inside prevented from entering the engine side along the hose.

Work vehicle

Large impacts act on a spoke wheel and spokes fastened by nipples tend to be loosened when a racing off-road motorcycle and the like repeatedly jumps and lands. A hub is connected with a rim by using deformed spokes each having a deformed portion. The deformed spoke is fastened while being elastically deformed so that the deformed portion extends by the nipple. As compared to a straight spoke, the deformed spoke has low longitudinal elastic modulus and substantially the same stiffness with a spoke having an equal diameter.

Spoke wheel and spoke using therefor

Provided is a high-frequency circuit apparatus and a communication apparatus whose consumption current is small and the inserting loss is small. One embodiment provides a high-frequency circuit apparatus constructed by an antenna duplexer of a frequency variable type; a first change-over switch which is electrically connected to an antenna terminal in the antenna duplexer; a second change-over switch which is electrically connected to a receiving terminal in the antenna duplexer; and a filter for reception which is electrically connected across the first and second change-over switches. As for the first and second change-over switches, a GaAs switch and a PIN diode switch, etc. are used. As for the filter for reception, a surface acoustic wave filter or monolithic ceramic LC filter, etc. is used.

High-frequency circuit apparatus and communication apparatus

The present invention provides a nonreciprocal circuit device which allows the relationship between the input and the output to be reversed using the identical terminal layout on a mounting substrate, only by preparing for a single type of nonreciprocal circuit device, and also provides a communication apparatus using this nonreciprocal circuit device. In this reciprocal circuit device, a plurality of centeral conductors are disposed on a ferrite on which DC magnetic field is to be applied, in a state of intersecting one another, matching capacitors are each connected between the ports of the centeral conductors and grounds, and a terminating resistor is connected between a predetermined port and a ground. In a resin case , input/output terminals which are conductively connected to the respective ports are disposed at substantially rotation-symmetrical positions with respect to the center of the bottom surface of the resin case.
