Title: Apparatus and Method for channel connection utilizing WDM in LAN
Inventor: YANG GEUN SU
IPC: H04B10/2581
Filed: 2000-08-30
Abstract: PURPOSE: A network generator using wavelength division multiplexing in a local area network and a channel connection method thereof are provided to reduce the possibility of collision by providing a plurality of channels to hosts of the network, and guarantee equity between hosts by preventing connection delay of the network and channel capture. CONSTITUTION: A host selects wavelength for frame transmission before transmitting frames and tunes lasers of a transmitter with the selected wavelength(ST21). A tunable transmitting part senses a carrier on the selected channel and starts frame transmission if the channel is idle(ST22¯ST23). In the case of transmitting a plurality of frames, the host transmits the first frame, and transmits the next frame after standing by during delay time between frames(ST25). If collisions are generated in frame transmission since other host tries transmission with the same wavelength, each host stops frame transmission promptly and transmits jamming signals(ST24, ST26). If the frequency of the collisions is lower than the designated maximum, the host tries transmission on the current channel after standing by during delay time obtained by a BEB algorithm(ST27¯ST28). If the frequency of the collisions is more than the designated maximum, the host jumps to the other arbitrary channel for trying transmission(ST29).

Title: Rotary clamping cylinder actuator
Inventor: ISHITANI YUICHI
IPC: B23Q3/06
Filed: 2000-10-13
Abstract: PURPOSE: To reduce the influence of inertial force produced by the pivoting of a clamp arm at an unclamping angle position. CONSTITUTION: A piston rod 40 being clamped advances leftwards. The clamp arm is moved axially from a workpiece clamping condition by engagement of a linear guide groove part 51 with a steel ball 54, and a piston 43 further advances so that the clamp arm is pivoted as it is axially moved from a clamping angle position to the unclamping angle position. At its pivoting end, the piston rod 40 tends to pivot in its pivoting direction because of the inertial force produced by the pivoting of the clamp arm, so the steel ball 54 is guided on an arc by an arcuate movement guiding surface 70a and smoothly shifts to the linear guide groove part 53 at the unclamping angle position. After moving axially, the steel ball stops at the unclamping angle position. Since the steel ball does not stop within a pivoting guiding groove part 52, the influence of the inertial force produced by the pivotal movement of the clamp arm can be reduced.
