Title: Oscillation mechanism for link member
Inventor: UMEDA KAZUTOSHI
IPC: D05B3/02
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To rapidly suppress the generation of vibration through simple mechanism at a stop of oscillation of a link member, increase the oscillation speed of the link member, and miniaturize an actuator for oscillation and drive. SOLUTION: A vertically extending link member 14 is oscillated and driven by a drive motor 12, and the support part on the lower end side of the link member 14 supported by a support mechanism 20. In the support mechanism 20, a fork part 14a formed at the support part of the link member 14 is engaged in a fit-in state with the eccentric shaft part 22b of an eccentric shaft member 22, and the pivoted shaft part 22a of the eccentric shaft member 22b is pivotally supported on a base plate 11. Since the upper end part of a leaf spring 23 is fixed and the lower end part of the leaf spring 23 is nipped in a pressed state by a pair of fixed blocks 25 and 26, when during a stop of drive by the drive motor 12, the link member 12 is vibrated, the eccentric shaft part 22b is rotated through the fork part 14a. Simultaneously, the pivoted shaft part 22a is rotated and the leaf spring 23 is elastically deformed. Vibration of the link member 14 is rapidly and effectively suppressed by the elastic energization force of the leaf spring 23.

A label (+) is given to the output signal line (f) of another AND gate 12 in the same way and a label (-) is given to the output line (g) of a NOT circuit 13 by negating the output of the circuit 12. When '1' is assigned to a signal line (a) and 'D' is propagated through the signal line (e) while an inspection pattern preparing algorithm is forwarded, the input lines (d), (e), and (i) of an OR gate 15 for unique activation are checked and the 'D' is not propagated through the signal line (i) having the (-) label, but 'O' is given to the line (i). As a result, the signal values of signal lines (g), (h), and (f) are found through normal agreeable operation.

Abstract: PROBLEM TO BE SOLVED: To enhance a network efficiency by allowing a base station to capture a code such as a preamble transmitted from a plurality of terminals through a reverse common channel from all available preamble signatures so as to reduce undesired data transmission and an interference signal. SOLUTION: A base station 200 captures a code such as a preamble transmitted from a plurality of terminals 100 through a reverse common channel from all available preamble signatures.
