Inventor: YOSHII MAKOTO
IPC: G05D5/02
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain enough rolling torque, and to avoid a deterioration in a rolling precision and the damage of a rolling equipment, caused by impact rolling torque while securing the responsiveness of the necessary control of the plate thickness by the hydraulic pressure, which corresponds to a rolling state. SOLUTION: When opening an opening/closing valve 12 and closing opening/ closing valve 13 and opening/closing valve 14, the hydraulic pressure from a servo valve 9B is directly supplied to a hydraulic pressure AGC cylinder 7, the responsiveness for controlling the hydraulic pressure AGC is improved, and the precision of the plate thickness is improved. On the other hand, when closing the opening/closing valve 12 and opening the opening/closing valves 13 and 14, since the hydraulic pressure from the servo valve 9B is applied via a hydraulic pressure buffer tank 15, an oil capacity is increased. In this way, the impact rolling torque at the time of rolling, which is controlled by a hydraulic pressure AGC cylinder 7, is relaxed. According to a control state, by changing over the opening/closing valves 12 to 14, optimum rolling is possible.

Title: Waveguide type ferrite phase shifter
Inventor: FURUKAWA MINORU
IPC: H01P1/195
Filed: 1979-06-21
Abstract: PURPOSE:To eliminate higher mode resosnance to improve performance, by providing a metallic plate in the space where a ferrimagnetic material is not provided in a square waveguide. CONSTITUTION:Thin metallic plate 7 is inserted in parallel with upper and lower walls of waveguide 1 and in the position of the approximately half height of the waveguide in the space where ferrimagnetic material 2 is not provided in square waveguide 1. By this constitution, higher mode resistance can be eliminated because metallic plate 7 reduces the height of the waveguide to the approximate half equivalently. In case that the effect is not sufficient due to the height of the waveguide, plural metallic plates 7 are inserted. Thus, higher mode resonance can be eliminated to improve performance without degradation of characteristics such as insertion loss, the phase shift extent, and used electric power.
