Inventor: NAGAI JUN
IPC: G03B5/00
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To attain natural camera shake correction by providing each means of detection, correction signal generation, correction and setting to the device. SOLUTION: A correction signal generating means 2 uses a filter 6 to process a signal from a shake detection means 1 as an angular velocity signal whose noise is cut off and uses filters 7, 8 to process the resulting signal into a correction signal. The means 2 sets variably a compensation value of the filter 8 via a characteristic setting means 5 to set a phase compensation characteristic and a gain frequency characteristic of a correction signal generated by the filter 8. The correction signal is fed from the means 2 to a correction means 3, in which a correction signal is given to a control section 13 from the filter 8 to vary an apex angle of the prism 11 sensed by a sensor 12 to correct a camera shake.  A phase versus frequency characteristic of the filter 8 is converted into a frequency of an angular velocity signal to compensate a phase lag effectively independently of a shake frequency of the camera.

Abstract: PROBLEM TO BE SOLVED: To prevent at a discharge port and prevent measuring accuracy from lowering, and allow drop transportation and pneumatic transportation by setting a weight average particle diameter in a specific range, and specifying an angle of repose measured by an injection method. SOLUTION: Resin beads are manufactured by using methacryl resin through a suspension polymerization method. After washing, this is subjected to flow- drying by heat air. Next, additives such as resin beads and water, oxide metal powder, fatty acid metallic salt are placed in a vessel-fixed type stirring machine to thereby be controlled by performing stirring in the order of 1-30 mins. The additive quantity of water is made in the order of, e.g. 0.1-2 pts.wt. with respect to 99.9-98 pts.wt. resin beads. Thus, the resin beads are formed having a weight average particle diameter being in the range of 50-800 μm, and 20-40 deg. of an angle of repose measured by an injection method.  As such, flowability is improved extremely, resulting in the prevention of segregation, coagulation, and the like within a tank and hopper, and clogging and so forth at the discharge port during the period of drop transportation and pneumatic transportation.
