Title: High frequency branching device
Inventor: MIYAMOTO YOSHIO
IPC: H03H7/48
Filed: 1987-07-21
Abstract: PURPOSE:To adjust optionally the branched coupling quantity, and to prevent the change in a branch coupling quantity from giving effect on the insertion loss of a main transmission line even if the said change occurs by inserting an attenuator having a prescribed attenuation to the branch output side of a branching circuit provided to a high frequency branching device. CONSTITUTION:A high frequency electric signal inputted to the high frequency branching device 1 is inflicted by a prescribed quantity of the insertion loss by a branching circuit 2 and is sent in the main transmission direction and part of the signal is branched while receiving a prescribed coupling loss. The branched signal is inflicted by a prescribed quantity of loss by an attenuator ATT and sent to the terminal equipment. The level of the branching signal reaching the terminal equipment is the logarithmic sum of the coupling loss inflicted while being branched by the branch circuit 2 and the attenuation of the attenuator. Since the inserted position of the attenuator ATT is at the branch output side of the branching circuit, even when the attenuation of the attenuator is changed, the coupling loss is unchanged and the insertion loss along the main transmission direction is unchanged. Thus, the branched output level is almost adjusted freely while keeping the output level sent to the main transmission line constant.

Abstract: PURPOSE:To improve the measuring limit by using a double-refraction crystal as a directional coupler, providing a polarization separating function, and deforming a part of a fiber to the measured in a loop shape and the like. CONSTITUTION:A measuring light beam 8 is cast into a directional coupler 4 (calcite crystal).

Meanwhile, the light beam 8 which is transmitted through the mirror 5 is cast into the optical fiber 7 to be measured. In a bending part 7a, the number of loops and the diameter of the loop are determined so that the characteristics of a 1/4-wavelength plate are obtained. The same effect as a 1/2-wavelength plate is generated during the time when the light beam 8 is reciprocated in the path to a reflecting end 7c to be measured. Furthermore, the loop plane is rotated, and the polarizing direction of the light beam 8 and the main axis of the wavelength plate are adjusted. The returned light beam 9 reflected from the reflecting end 7c is cast into the couple 4 and then cast into a light output meter 12. Therefore, only the light beam 9 can be selectively measured.

Abstract: PURPOSE:To convert the time base of picture data at high speed through simple circuit configuration by controlling the update of the write-in address and the read-out address of a picture memory by a control pulse. CONSTITUTION:Input picture data DI is written in the picture memory 10 according to the write-in address AW, and besides, it is read out from the picture memory 10 as output picture data D according to the read-out address AR.

Besides, the input picture data DI is inputted continuously synchronously in a write-in clock CW. As for the picture data to be written in the picture memory 10, the input picture data DI at the point of time when the control pulse Y becomes logical '1' is selected and written in. Thus, by reading out continuously the picture data written in the picture memory 10 after being thinned according to the read-out address AR, the picture data whose time base is compressed can be obtained at high speed.
