Title: Method for formation of optical timing pulse and optical timing circuit
Inventor: YONEYAMA KENICHI
IPC: H04B10/516
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To enable stable operation with high cost effectiveness and small-sized and simple constitution by branching an optical signal, adjusting the two branched light rays in such a manner that the optical path lengths thereof vary from each other, then multiplexing the branch light rays and forming optical timing pulses from the multiplexed light. SOLUTION: The optical data signal of a non-return two-zero(NRZ) type is inputted to an input port 15 of a Mach-Zehnder type optical circuit 1 where the optical data signal is branched to two rays by a first 3 dB optical coupler. The branched light rays pass optical paths A, B varying in the optical path lengths and a deviation occurs by the prescribed time between the two optical data signals. The two optical data signal are again coupled by the next 3 dB optical coupler and the coupled light is outputted at a prescribed waveform from optical output ports 17, 18. The clock frequency component equal to a bit rate exists in the optical data signal outputted from the optical output port 18.  When this optical data signal is made incident on a semiconductor mode synchronizing laser 3, this semiconductor mode synchronizing laser 3 forms the optical timing pulse of the repetitive frequency equal to a clock frequency.

Abstract: PURPOSE:To minimize the abrasion of a brush, and carry out commutation normally, by moving a brush support member in accordance with the rotational speed of a rotary machine toward the center of a commutator so as to vary the pressing force of the brush. CONSTITUTION:A brush 3 is inserted into a brush retaining hole 1a provided in a brush holder body 1, and urged by a coiled spring 6 toward a commutator 2a.

Thus, the position of the optical low- pass filter 20 is changed-over in accordance with the operation mode so that high frequency component of the prescribed frequency or above is cu by considering ink dot resolution and the cause of the moire and the nounifomity is eliminated.
