Patent JP-S62101806-A (JP)
Title: Speed control switching device
Inventor: KAWAI TAKUMI
IPC: F01D19/00
Filed: 1985-10-30
Abstract: PURPOSE:To constantly minimize the fluctuation in the turbine output so as to enhance the operational stability at the time of switching of a speed control system by regulating the opening of each valve so that the steam flow rate of a plurality of governing valves varies at a constant ratio with respect to the difference in steam flow-rate between before and after the switchings. CONSTITUTION:When a governing system is switched from the throttle governing to the nozzle governing, switching ratio signal generators 9 and 10 gradually move to the nozzle governing side by means of a driving circuit 11 for the switching. As a result, a switching control signal 13 gradually varies from 0 to 1, while a switching control signal 14 from 1 to 0, respectively, both at the same ratio. At this time, if the output of the basic control function 1 is constant, the outputs from steam flow-rate switching functions 4alpha and 4beta are proportionally distributed by each signal 13 or 14, and a predetermined value is output at an adder 6. As a result, opening-inversely-conversing functions 7alpha and 7beta issue a governing valve opening command. Based on this opening command, valve position control circuits 8alpha and 8beta control the actual valve position.

Title: Liquid crystal shutter
Inventor: NAKATSUKA YOSHITOSHI
IPC: G02F1/13
Filed: 1990-09-11
Abstract: PURPOSE:To obtain a liquid crystal shutter which changes the light shield/ transmission state of a liquid crystal plate from one state to the other by fitting solar battery which serves as a photodetection sensor and a power source integrally with a liquid crystal plate. CONSTITUTION:The solar battery 4 which serves as the photodetection sensor and the power source for controlling the light shield/transmission state of the liquid crystal plate 3, and its controller are fitted in an integrally incorporated state at the center part on the same plane of a signal 1 with the liquid crystal plate 3 on the side of a lens 2. Then the liquid crystal plate 3 at the lens position where the lamp of the signal 1 illuminates changes from the light shield state to the light transmission state with an output voltage, generated with the light of the lamp of the signal 1 received by the solar battery 4, and a signal is passed through a liquid crystal shutter 7 and displayed by illumination. The liquid crystal plate 3 at the lens position where the lamp of the signal 1 does not illuminate, on the other hand, is still in the light shield state since the solar battery 4 generates no output voltage. Consequently, the liquid crystal plate 3 changes from the light shield state to the light transmission state or vice versa.
