Abstract: A rolling contact bearing assembly includes a cage including two or more arcuate members each having a plurality of pockets defined therein for accommodating a corresponding number of rollers arranged consecutively in a circumferential direction to form a ring shaped assembly. The arcuate members are connected together by a retention ring, having an elasticity, over a circumference of the cage. The arcuate members are displaced radially outwardly against an elastic compressive force of the retention ring such that circumferential gaps are formed at joints between the neighboring arcuate members. The arcuate members are held in a condition movable in the circumferential direction by a distance equal to the size of the circumferential gaps.

A retainer is constituted by an annular member made from a flat steel plate; has a main body area in its widthwise intermediate region. The main body area has its outer circumferential edge formed with an outer circumferential engagement edge which is lower than a surface of the main body area. A large number of pockets are equi-spaced in a circumferential direction of the main body area in the thickness direction. Each of the pockets has a guide surface formed with anti-dropping projections of a roller for preventing the roller from dropping.

Abstract: A communication system has a communication control unit, communication terminal units and communication units. The communication control unit and the communication terminal units communicate according to a first protocol. The communication units mutually communicate according to a second protocol. A specific communication unit of the communication units has a data analyzer and a data transmitter. The data analyzer judges whether or not second monitoring information represents a steady state. The data transmitter transmits the control information corresponding to the second monitoring information to at least one related second communication terminal unit through the communication control unit according to the first protocol if the second monitoring information represents an unsteady state. Thereby, the load connected to the second communication terminal unit is controlled.

Abstract: A communication device 1 has a first protocol analysis section 11 that analyzes a status of a transmission signal Vs received at a transmission signal receiver 10. A transmission controller 14 determines a communication available period and a communication unavailable period based upon the analysis result. When the communication available period is determined, the transmission controller 14 allows a second protocol signal transmitter 12 to transmit a packet in accordance with a second protocol to a signal line Ls. With this result, it is possible to transmit a relatively large amount of data while suppressing noise influence caused by a varying condition of a carrier, in contrast to a prior system in which the transmission signal is superimposed only by a simple determination of the carrier condition. Thus, it is possible to share the signal line Ls with the time-division multiplexing transmission system and improve reliability of data transmission.

Abstract: Two or more arcuate members (2A, 2B), each having a plurality of pockets (3) defined therein for accommodating corresponding rollers, are placed one above the other to form a ring shaped assembly and are subsequently connected non-separably together by means of a retention ring (4) to thereby complete the cage (1). The arcuate members (2A, 2B) are so connected together that its inner periphery may assume a position radially inwardly of the outer diameter of a shaft such that in a condition having been assembled onto the shaft, they can displace in a direction radially outwardly against an elastic compressive force of the retention ring (4) to invite a circumferential gap (S) at each joint between the arcuate members (2A, 2B).

Typically, a weight ratio of granules having a diameter of 0.1 mm or less is 2.0 wt % or less and a median diameter is 0.17 mm or more. The granular surfactants are easily manufactured and have high water solubility, reduced powder dust, and fluidities.

Abstract: A tool with a blade is provided at a molding die and set so as to protrude further inwardly than the molding surface of the molding die. When a parison is expanded within the molding dies, the parison is brought into close contact with the outer peripheral wall of the tool. A hollow body is formed in a state in which the inner wall surface of a through-hole is molded by the outer peripheral wall of the tool. Thereafter, the tool is advanced and a cut-out piece is excised. A washer tank is thereby formed. The inner wall surface of the through-hole is not a cut surface and the through-hole is formed in accordance with the outer peripheral wall of the tool.
