Title: Method and apparatus for measuring fluidity
Inventor: ISHIZAKI KANJIRO
IPC: G01N11/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To measure the fluidity of a cement-based material having high fluidity easily and accurately by detecting the rotary driving force of a stirring blade before an imaginary plane formed by the upper end thereof, is covered completely by the liquid of cement-based material (solidification material). SOLUTION: A kneading tank 1 is filled up to a specified height with a solidification material, e.g. cement especially mortar, which is then stirred and kneaded by rotating a stirring blade 3, having the ratio of diameter with respect to the inside diameter of tank 1 in the range of 0.5-0.9, at a predetermined speed. The rotational speed is controlled so that the imaginary plane formed by the upper end of blade 3 is not covered at least partly with the surface layer plane of mortar material to be stirred and the driving force (motor current) required for rotating the blade 3 is detected. The driving force is expressed in terms of the fluidity data (P tunnel flow-down time) of mortar material according to a working curve stored in a CPU. Since the error is suppressed in the data thus obtained, highly accurate measurement can be realized.

Title: Driving system of electromagnetically driven shutter
Inventor: SUZUKI RIYOUICHI
IPC: G03B7/08
Filed: 1978-06-21
Abstract: PURPOSE: To enable large current to be supplied from a capacitor to the coil of a motor only when high speed second time is required by discriminating the subject luminance level and changing over the first and second power source device outputs.  
     CONSTITUTION: When a switch MSW is closed in an electromagnetically driven shutter device which is electromagnetically opened and close by an electromagnetic driving device, a constant voltage is generated from a constant voltage circuit 31 and the voltage corresponding to the subject luminance is generated in the output of an operational amplifier OP 1. When the subject luminance is high, a switching transistor TR 1 goes ON to supply power from a battery 30 to a DC boosting circuit 39, by which capacitors C 1 , C 2  are charged. When the shutter is released in the state where this charging is completed, the charge amounts from the capacitors C 1 , C 2  flow in the coil 9 of the electromagnetic driving device, whereby, the shutter opening and closing operations are accomplished. When the subject luminance is low, the operation level of the operational amplifier OP 1 does not rise and the boosting circuit 39 does not operate, thus the low voltage is supplied to the coil 9 from the constant voltage circuit 31.
