Abstract: A valve operating system in an internal combustion engine includes a switchover pin which is movable between an associatively operating position where adjacent ones of rocker arms are operated in association with each other, and an associative-operation releasing position where the associative-operation is released, the switchover pin receiving at axially opposite ends thereof a hydraulic pressure force acting toward the associatively operating position and a spring force acting toward the associative-operation releasing position, a cylindrical roller shaft which is fixed to one of the adjacent rocker arms, and into which the switchover pin is slidably fitted in response to the movement thereof toward the associatively operating position, and a roller rotatably carried on the roller shaft to come into rolling contact with a cam provided on a camshaft. In this valve operating system, at least one of axially opposite end surfaces of the roller shaft formed of a material harder than that of the one rocker arm, which receives the switchover pin, protrudes from a side surface of the one rocker arm. Thus, a wear powder can be prevented from entering into the roller shaft, thereby ensuring the smooth switching-over operation of the switchover pin.

Abstract: The present invention includes processes and resulting structures for producing a modified polymer (25) having interconnecting channels (45). The interconnecting channels (45) act as controlled transmission passages through the polymer. A hydrophilic agent (35) is blended into the polymer so that it is distributed within the polymer. In one embodiment, an absorbing material (30) is blended into the polymer so that the absorbing material is distributed within the product. The product is solidified so that the hydrophilic agent (35) forms passages (45) in the product through which a desired composition is communicable to the absorbing material (30) that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts (55) and liners (70) for closed containers, or it may be formed into a film, sheet (75), bead, or pellet.

Abstract: Conventionally, in order to downsize the enclosure, there was no other choice than downsizing the enclosure and decreasing the area of the lens plate, or increasing the area of the lens plate and increasing the enclosure as well. However, decreasing the area of the lens plate disadvantageously lowers brightness of illumination. In contrast to this, when the dimensions of the lens plate are increased, the proportion of the area of the lens plate with respect to the roof increases, which leads to a problem in terms of design. Accordingly, the present invention provides an interior light system for vehicles comprising a lamp accommodated in the enclosure, a push switch for turning on and off the lamp fixed in the enclosure, and a lens plate journaled at the ends of the opening of the enclosure for a swinging motion, in which the push switch is turned on and off by pressing the lens plate, thereby turning the lamp on and off.

Abstract: An on-machine-seamable papermaker's fabric, which may be produced by modified endless weaving, includes machine-direction (MD) and cross-machine-direction (CD) yarns. When so produced, the MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. Interwoven with at least one of the two sides, top and bottom, of the seaming loops at one or both widthwise edges are at least two additional CD yarns. The additional CD yarns interweave with the top and/or bottom of the seaming loops in a leno weave, which keeps the seaming loops in a common position vertically relative to the plane of the papermakers fabric, locks the seaming loops into a desired position and orientation with their planes perpendicular to that of the papermaker's fabric.

Abstract: A wireless network communication system consists of an access server for facilitating communication between a network resource interfacing with the access server over a land-based network and a wireless communications device interfacing with the access server over a wireless network. A message intended for transmission from the wireless communication device to the network resource is transmitted to the access server over a wireless network as a number of message datagrams. Upon receipt of the message datagrams over the wireless network, the access server generates and transmits to the wireless communication device an acknowledgment datagram indicating successful receipt of each message datagram, and transmits the successfully received message datagrams to the network resource over the land-based network. If a message datagram is not acknowledged, the wireless communication device continues to retransmit the unsuccessfully transmitted message datagram at a retransmission rate based on a running average of acknowledgment times for successfully transmitted ones of the message datagrams.
