Title: Star coupler
Inventor: SANO SHO
IPC: G02B6/28
Filed: 1988-01-21
Abstract: PURPOSE:To secure the communication of a whole network even when rays of light are continuously inputted to one of input terminals by providing liquid crystal plates whose light transmittance or reflectivity is variable between the input terminals and a light mixing section. CONSTITUTION:Optical fibers 41-4n respectively connecting input terminals 21-2n to a light mixing section 1 bare cut in the middle in the length directions and liquid crystal plates 61-6n are provided between the cut ends of the fibers 41-4n. Then by connecting respective paired terminals a1, b1-an, bn of the liquid crystal plates 61-6n to each other and applying drive voltages across the paired terminals, rays of light are passed among the optical fibers 41-4n or the rays of light are intercepted among the optical fibers. Therefore, one of the input terminals, to which optical signals which are harmful for carrying out optical communication are inputted, can be disconnected from the light mixing section. As a result, it can be prevented that a whole network goes to unable for carry ing out communication due to a fault occurring in one route in which rays of light continuously exist.

Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To adjust a control cycle when the time of control cycle of vehicle speed is shorter than an objective control cycle time by adding difference between the objective control cycle time and the control cycle time to a pressurization beginning delay time of this time, and delaying a pressurization beginning point of the next time by a pressurization beginning delay time of the next time. SOLUTION: At first a control cycle between the high peak of control speed of this time and the next high peak is measured (S1). Next, it is judged whether the present control is a pressurization mode or not (S2), and in case of the pressurization mode, it is judged whether it is the beginning point of the pressurization mode or not (S3). When it is judged to be the pressurization mode beginning point, the delay time of the pressurization beginning point of the next time is obtained (S4). Further it is judged whether the obtained pressurization delay time is passed or not (S5), and in case of passing, ordinary pressurization is begun (S7). Hereby, vibration of a vehicle body at anti-lock control can be restrained.
