Abstract:
A bicycle hub assembly includes a hub axle, a hub shell, a bearing unit, a retaining member, a lock member and an intermediate member. The bearing unit has a first ring that is coupled to the hub axle, a second ring that is coupled to the hub shell, and a plurality of rollers that is disposed between the first and second rings. The retaining member is coupled to the first ring and retains an axial position of the first ring with respect to the hub axle. The retaining member includes a first attachment face. The lock member is fixedly coupled to the hub axle. The lock member includes a second attachment face that faces the first attachment face of the retaining member. The intermediate member is disposed between the first attachment face of the retaining member and the second attachment face of the lock member.
Abstract:
A bicycle hub kit includes a hub axle, a hub shell, a bearing unit, first and second end nuts, and a retaining member. The bearing unit has a first ring, a second ring, and a plurality of rollers. The first and second end nuts are interchangeably coupled to an axle end of the hub axle. The retaining member retains an axial position of the first ring of the bearing unit with respect to the hub axle. The retaining member is disposed between the first ring of the bearing unit and one of the first and second end nuts. The first and second end nuts have first and second through holes, respectively. The second through hole of the second end nut has an inner diameter that is smaller than an inner diameter of the first through hole of the first end nut.
Abstract:
A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, a pair of bead cores disposed one in each of the bead portions, and a carcass ply extending between the bead portions through the tread portion and sidewall portions, wherein the carcass ply is composed of windings of at least one carcass cord looped around the two bead cores in a helical manner and/or figure-of-eight manner.
Abstract:
A base-station apparatus measures a frequency variation and time variation based on a signal transmitted from a mobile machine. Then, based on the measured frequency variation and time variation, the base-station apparatus allocates either an adjacent sub-channel or a distributed sub-channel to the mobile machine. With this, the base-station apparatus allocates a sub-channel according to the wireless propagation environment where the mobile machine is located.
Abstract:
A radio communication apparatus including: a radio communication interface; and a processor; the processor being configured to detect a first radio communication apparatus and a second radio communication apparatus based on a piece of address information received by the radio communication interface; and to select one of a first layer and a second layer as a forwarding layer, in which a packet is forwarded to a next forwarding address according to the radio communication apparatus of the next forwarding address corresponding to a destination address of the packet.
Abstract:
The invention provides a transmission fluid composition which has a kinematic viscosity as determined at 100° C. of 2 to 10 mm2/s and a viscosity index of 150 or higher and which satisfies a relationship between kinematic viscosity and NOACK evaporation loss amount represented by formula (I): X/3+Y≦6.33 (I) (wherein X represents a kinematic viscosity (mm2/s) as determined at 100° C., and Y represents a NOACK evaporation loss amount (mass %) at 200° C. for one hour), and a transmission fluid composition containing, as a base oil, at least one species selected from among α-olefin oligomers produced through oligomerization of an α-olefin through a specific method and hydrogenation products of the oligomers. Such transmission fluid compositions exhibit a very small evaporation loss despite having low viscosity, and a long metal fatigue life (e.g., pitting resistance) and have high viscosity index, good low-temperature fluidity, good extreme pressure properties, and good oxidation stability, and are suitable for transmissions, particularly automatic transmissions.
Abstract:
A bicycle hub axle adapter basically includes a hub axle adapter main body and at least one retaining member. The hub axle adapter main body is configured to be inserted into a bicycle hub having a hollow hub axle. The at least one retaining member is disposed on an external surface of the hub axle adapter main body for contacting an internal surface of the hollow hub axle.
Abstract:
A bicycle wheel rim structure is provided with a rim, a cap and a tape. The rim includes a first annular side portion, a second annular side portion and an annular bridge portion extending between the first and second annular side portions. The bridge portion has at least one opening. The cap includes a base plate and a projection. The base plate overlies an outer rim surface of the annular bridge portion. The projection extends from the base plate into the at least one opening. The tape is attached to the outer rim surface of the annular bridge portion and overlying the base plate of the cap. The tape is dimensioned to cover an interface between a peripheral edge of the base plate of the cap and the outer rim surface of the annular bridge portion.
Abstract:
A sensor device includes a detector portion, plural metal terminals that transmit a detection signal from the detector portion, and a housing portion, which integrally supports the detector portion and metal terminals, formed from resin, leading end portions of the plural metal terminals configuring connector terminals, and the plural metal terminals being disposed with at least one portion thereof aligned when seen from the axial direction of the connector terminals, wherein protruding portions protruding in a direction differing from the axial direction of the connector terminals are provided on the metal terminals.
Abstract:
The objects of the invention are to provide a sheet chuck that enables a flexible sheet substrate to come in uniform contact with a stamp, and a microcontact printing process of using that sheet chuck to form a high-precision pattern. The sheet chuck of the invention comprises a base having a sheet substrate carrying surface defined by an upper surface thereof, a suck-in/suck-out port positioned on the carrying surface, and a holder positioned on the carrying surface in such a way as to surround the suck-in/suck-out port, and the suck-in/suck-out port is an area capable of sucking in or sucking out gas.
