Title: Long optical axis, self-centering rodlike optical element
Inventor: YATABE YOSHIO
IPC: G02B3/06
Filed: 1983-02-23
Abstract: PURPOSE:To obtain an optical element having complicated and diverse function in which focal line of luminous flux is constituted in the element and different in optical function depending on the structure of rear part by forming a front refraction cylindrical face in the direction of incidence of light. CONSTITUTION:Faces of an optical element 1001-1009-1002-1005-1010-1006 constitute a circular-arcuate face making OO' a center axis. P1R1, S1Q1 and P2R2, S2Q2, are aperture of lenses, and F, F' is focal line of front refraction cylindrical face. The same direction with the front refraction cylindrical face, i.e. direction of incidence of light can be made a convex cylindrical face of a rear refraction cylindrical face. Or, it can be made concave in reverse direction, i.e. in the direction of incidence. Further, only central part can be made a refraction circle. When it is made a convex lens in which peripheral parts 1004-N1, 1003-N2 which are indifferent to transmission of light are perpendicular to the optic axis and only contral openings N1, N2 are projected backward, if the radius of curvature is made stronger, the position of the second focal line F2 formed by converged divergent light is put out to the space. By placing another optical element here, a more complicated optical product can be obtained.

Title: Drum type washing machine
Inventor: YAMAZAKI FUMIYOSHI
IPC: D06F33/48
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To lessen unbalance of clothing which causes vibration and to realize reduction of vibration by providing plural steps of rotating a drum at a rotating speed lower than the rotating speed for dewatering before the drum reaches a designated rotating speed for dewatering, and controlling in such a manner that in one step among the above, the rotating speed becomes lower than that in the preceding step. SOLUTION: As shown in a timechart of the figure, before reaching a designated rotating speed N0 for dewatering, a spinning tub repeats normal rotation at 50rpm, stopping, reversion and stopping several times, and then rotates at such a rotating speed N1 that washing sticks to the inner peripheral surface thereof. Next, the rotating speed is reduced to such a rotating speed N2 that the centrifugal force is balanced with the center of gravity in inner peripheral radius position of washing put in the ideal state of uniformly sticking to the inner peripheral surface. Thus, washing in the unbalanced part has a smaller radius of rotation, so that only the washing of the unbalanced part drops repeatedly, thereby untangling the washing. Finally the radius of rotation balancing with the center of gravity can be attained to uniform the washing.  After the rotation at the rotating speed N2 for designated time, it transits to designated rotating speed N0 for dewatering.

Title: Geothermal heat collecting system
Inventor: ORII TSUNEKAZU
IPC: F24J3/08
Filed: 1983-02-22
Abstract: PURPOSE:To prevent the lowering of temperature in the space under the floor of a building or in a hot house by a method wherein geothrmal heat is collected by making use of the natural circulation of air. CONSTITUTION:A pipe A which is used to collect geothermal heat is made of a good heat conductive material and the upper part AU of the pipe is formed of a heat insulating material. The reason for this is that the geothermal heat near the surface of the ground is subject to the influence of the open air temperature and when the open air temperature is low, it has a temperature much lower than that in the deep part of the ground. A pipe B is required to be thermally insulated to a sufficent degree lest the temperature in the space within the pipe should by influenced by the geothermal heat. Such pipes A and B are made to communicate with each other through a connecting pipe C and the upper ends of these pipes A and B are made to open in the under-floor space or in the hot house on the ground. As a result, the chill in the underfloor space or in the hot house is heated by the geothermal heat to thereby prevent the lowering of the temperature in the underfloor space or in the hot house.
