Title: Method and device for pre-compensating refractive characteristic of human eye by adaptive optical feedback control
Inventor: BILLE JOSEF
IPC: A61B3/107
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for measuring the refractive characteristic of a human eye and precompensating it using adaptive optical elements. SOLUTION: A system 10 for precompensating the refractive characteristic of an eye includes optical components 16, 26, 28 for directing optical beams to the eye 12 in order to obtain reflection from the retina of the eye 12. reflected beams including refractive aberration caused by the eye 12 are separated into a plurality of individual beams by a small lens array 50.

Title: Drum type washing machine
Inventor: MURAKAMI KAZUSHIGE
IPC: D06F33/02
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To surely prevent abnormal vibration of a drum and an outer tube during spin-drying and reduce load imposed on a bearing. SOLUTION: The drum 5 is arranged in an inclined position such that an opening 5a in the drum 5 for casting clothes faces up. During spin-drying, when balance is adjusted by rotating the drum 5 at a rotational speed such that a centrifugal force acting on laundry contained in the drum 5 is smaller than gravity, the laundry in the drum 5 is entirely moved toward a rear end face and biased. Therefore, even if eccentric load is produced by the localization of the laundry about an axis, the probability of its position being located at the rear of the drum 5 as seen along the axis is very high. Thus, because the distance between the eccentric load and the bearing 10 is short, oscillation can be made relatively small even in the presence of the eccentric load, and the load imposed on the bearing 10 can also be made small.
