Title: Method and device for producing optical branching device
Inventor: TSUGITA HIROSHI
IPC: G02B6/28
Filed: 1989-03-01
Abstract: PURPOSE:To easily obtain a desired branch ratio and to produce an optical branching device with a good reproducibility by providing each branch optical fiber in a bundle part with a core and a clad and approximately equalizing a sectional area ratio of respective branch fibers to the branch ratio. CONSTITUTION:One trunk optical fiber 17 and a bundle part 18 of plural branch optical fibers 11 and 12 are connected with equal sections areas. Consequently, the loss is reduced when an optical signal is transmitted not only from the trunk optical fiber 17 to branch optical fibers 11 and 12 but also from branch optical fibers 11 and 12 to the trunk optical fiber 17. Since branch optical fibers 11 and 12 have clads respectively in the bundle part 18, light is not transmitted between adjacent optical fibers, and the branch ratio is given by an area ratio of cores on end faces of branch optical fibers 11 and 12, and this ratio is approximately equalized to the sectional area ratio of branch optical fibers 11 and 12. Thus, a desired branch ratio is easily obtained, and this optical branching device is used for bidirectional communication also, and the device is produced with a good reproducibility with respect to branch ratio.

Title: Fault point locator
Inventor: WACHI ISAO
IPC: G01R31/08
Filed: 1988-03-03
Abstract: PURPOSE:To enable accurate measurement of the distance to a fault point, by detecting a fault phase in which a ground fault of a transmission line occurs in a transmission system including a branch power source. CONSTITUTION:A fault phase in which a ground fault of a transmission line occurs is detected in a transmission system containing a branch power source 8 by a fault phase detecting means. Then, a reactive power is calculated by a first digital computing means with a zero- phase current flowing to a fault point F of the fault phase as the reference from voltage and current values at a point P0 where a detecting means is set. To the calculated reactive power, a reactive power generated by an outflowing current from the branch power source 8 is added, and the results are defined as the reactive power value. Then, a second digital computing means calculates a reactive power with a zero-phase current per unit length of the transmission line as the reference from a current value at the set point P0 and a line constant of a transmission line 1. To this reactive power, the reactive power portion generated from the outflow current from the branch power source 8 is added, and the results are outputted as the reactive power value per unit length of the transmission line. Moreover, the reactive power value from the first computing means is divided by the reactive power value per unit length of the transmission line from the second computing means by a third digital computing means to calculate the distance to the fault point F from the set point P0.

Abstract: PURPOSE:To improve the responding property of a fuselage as well as the performance of a guided missile by a method wherein fore wings and main wings are moved forwardly by one set of control device after igniting a rocket motor and two kinds of steering surfaces are steered simultaneously. CONSTITUTION:When a control device 5 receives a signal that the ignition of a rocket motor 10 is finished, the control device 5 operates the forward moving mechanism 9a of fore wings and the forward moving mechanism 9b of main wings to move the fore wings and the main wings from the positions, shown by broken lines in a diagram, to the forward positions, shown by full lines in the same. According to this method, the point Xcp1 of action of aerodynamic force of a fuselage moves to a point Xcp2 and a distance between the point of action of aerodynamic force and the position of the center of gravity Xm2 is shortened from DELTAX2 to DELTAX3 whereby the responding property of the fuselage may be improved. Upon turning, the control device 5 operates the actuator 6a of the fore wings 2 so as to elevate the leading edges of the fore wings 2 and operates the actuator 6b of rear wings 4 so as to descend the leading edges of the same. According to this method, the responding property of the fuselage may be improved and a high trim angle may be obtained since the steering angle of the fore wings 2 in a positive direction may be smaller whereby larger maximum acceleration may be obtained.
