    摘要： While an operating angle or a lift of an engine valve (211) is modified within a predetermined operating angle range or lift range, variation in an opening timing of the engine valve (211) is suppressed by displacing a rocker shaft (216b) relative to a drive shaft (213) such that an opening timing variation of the engine valve (211) accompanying angular variation in a straight line linking a center of the drive shaft (213) and a center of the rocker shaft (216b) and an opening timing variation of the engine valve (211) accompanying variation in a distance between the center of the drive shaft (213) and the center of the rocker shaft (216b) cancel each other out.

    摘要： A network system connects with processes P1 to P5 that can mutually send and receive a broadcast message specified with no destination and a message specified with a specific process portion and change their states to parent or child processes. For example, process P1 is a parent process and processes P2 to P4 are child processes. When processes P1 to P4 constitute a group, each of child processes P2 to P4 stores parent process P1. Parent process P1 stores each of child processes P2 to P4 that store itself (P1). When process P5 in another group is connected, parent process P1 exchanges a message with process P5 for negotiation to determine either to be a parent process and change the other to a child process.

    摘要： A variable valve operating system of an internal combustion engine includes a first variable mechanism capable of variably controlling a lift characteristic of an intake valve, and a second variable mechanism capable of variably controlling a valve-open and/or valve-close timing characteristic of the intake valve. A position detector detects current actual positions of the first and second variable mechanisms. A controller responds to a detected failure position of one of the first or second variable mechanisms by controlling movement of the other of the variable mechanisms within a predetermined range that avoids interference between the engine valve and a piston and between the intake and exhaust valves when the one variable mechanism fails.

    摘要： A variable valve actuation (VVA) apparatus is disclosed. The VVA apparatus can keep an engine cylinder valve closed. Rotating a camshaft in timed relation with a crankshaft of the engine causes an eccentric crank cam to move a link or crank arm, thereby causing one end of a rocker arm to reciprocate. This causes the other end of the rocker arm to reciprocate. The reciprocating motion of the other end of the rocker arm is transmitted via a link to a valve operating (VO) cam, thereby causing the VO cam to pivot to push a valve lifter for opening the associated cylinder valve. An eccentric circular cam, fixed to a control rod, supports the rocker arm for rotation relative thereto in such a manner that rotation of the control rod causes a pivot center of the rocker arm to move, thereby changing position of the VO cam relative to the valve lifter. The change in the position of the VO cam causes its valve lift diagram to change. The VO cam has a base circle portion that extends over a predetermined angle with respect to the center of pivot of the VO cam and the contiguous ramp portion. A predetermined valve clearance exists between the VO cam and the valve lifter when the base circle portion faces the valve lifter. When it is desired to keep the associated cylinder valve closed, the control rod is rotated to establish a state wherein the VO cam pivots to bring not only base circle but also the ramp portions into facing relation with the valve lifter. In this state, the maximum cam lift of a cam lift diagram is greater than zero and less than the valve clearance.

    摘要： A drive shaft is synchronously driven by an internal combustion engine. A cylindrical hollow cam shaft is rotatably disposed about the drive shaft. The cam shaft has thereon a cam which actuates a valve of the engine. A first flange is formed on one end of the cam shaft. A second flange is connected to the drive shaft to rotate therewith. The second flange faces the first flange. First and second radially extending grooves are formed in mutually facing surfaces of the first and second flanges respectively. The first and second grooves are arranged at opposite sides with respect to an axis of the drive shaft. An annular disc is disposed between the first and second flanges. The annular disc has first and second pins which are slidably engaged with the first and second grooves respectively. A control housing rotatably receives therein the annular disc. The control housing is pivotal in a direction perpendicular to an axis of the drive shaft and has therein a cam receiving circular opening. A control shaft has thereon a circular eccentric cam which is slidably received in the cam receiving circular opening of the control housing. A pair of annular flanges are provided on the control shaft to intimately put therebetween a thicker portion of the control housing thereby to suppress an undesired axial displacement of the control housing on and along the control shaft.

    摘要： A cylinder valve control stem for a vehicle drivetrain including a transmission and an engine having a variable valve control mechanism which can vary valve lift diagram in response to a control signal. A controller develops the control signal in response to varying operating condition of the engine. The controller derives, upon initiation of a shift in the transmission, engine speed to be established after completion of the shift and corrects the control signal such that the variable valve control mechanism provides one of various valve lift diagrams whose predetermined value in engine speed is not exceeded by the derived engine speed.

    摘要： A robot hand having an attachment portion that is held when incorporated into a robot includes CFRP laminated to each other and a vibration-damping elastic layer that is disposed between the CFRP layer and the CFRP layer. The vibration-damping elastic layer includes viscoelastic resin regions including a viscoelastic resin and a high-rigidity resin region including high-rigidity resin. The viscoelastic resin regions and the high-rigidity resin region are alternately arranged along the direction intersecting the longitudinal direction of the CFRP layer in the attachment portion. The viscoelastic resin regions improve vibration-damping properties on the robot hand. As the viscoelastic resin regions and the high-rigidity resin region having relatively higher rigidity are alternately arranged along the direction intersecting the longitudinal direction of the CFRP layers, flexural rigidity along the longitudinal direction of the CFRP layer is improved.
