    • This invention relates to a fiber optic polarization controller which controls the polarization direction of the light propagating through an optical fiber by curving a single-mode fiber within an imaginary plane S to generate birefringence on the fiber and by rotating the plane S defined with the thus curved portion. The invention aims to prevent twists of the optical fiber which are caused in rotating the plane S by rotating the fiber in one direction from the plane S simultaneously with the rotation of the plane S and correspondingly to the angle thereof. The optical fiber may be rotated either by utilizing the stability of fiber which is held loosely at a curved portion or by forcibly rotating the curved portion from outside.

    • The optical nonreciprocal device is used to optically couple together two opposed optical fibers. The light from one optical fiber is separated into ordinary ray and extraordinary ray by a first birefringent crystal member. The separated ordinary and extraordinary rays are subject to a total of 90.degree. polarization rotation by transmitting in a forward direction through a magneto-optical member having an angle of polarization rotation of 45.degree. and through a compensating plate. The separated ordinary and extraordinary rays are synthesized by transmitting through a second birefringent crystal member and then applied to the other optical fiber. A lens is interposed between one optical fiber and the first birefringent crystal member for causing the light to propagate through the light path while being converged or diverged. By suitably selecting the thicknesses of the first and second birefringent crystal members, the ordinary and extraordinary rays propagating from the second optical fiber to the first optical fiber in the reverse direction are prevented from being overlapped at the incident end of the first optical fiber thus providing an optical isolator.
    • 光学非可逆器件用于将两个相对的光纤光学耦合在一起。 来自一个光纤的光被第一双折射晶体部件分离成普通的光线和非常的光线。 分离的普通和非凡光线通过向前方向通过偏振旋转角为45°的磁光部件通过补偿板传播总共90°的偏振旋转。 分离的普通和非凡光线通过透射通过第二双折射晶体部件合成,然后施加到另一光纤。 在一个光纤和第一双折射晶体部件之间插入透镜,用于使光在会聚或发散的同时通过光路传播。 通过适当地选择第一和第二双折射晶体构件的厚度,防止从第二光纤向相反方向传播到第一光纤的普通和非常的光线在第一光纤的入射端处重叠,从而提供 光隔离器。

    • Below 50-nm-diameter extremely narrow electrically-conductive fiber is used instead of the electron beam biprism used in the conventional interference electron microscope method. A phenomenon is utilized where a focus-shifted shadow of this fiber is shifted from a straight line by a distance which is proportional to a differentiation of phase change amount of an electron beam due to a sample with respect to a direction perpendicular to the fiber. The phase change amount is quantified by calibrating this shift amount through its comparison with a shift amount caused by another sample in terms of which the corresponding phase change amount has been quantitatively evaluated in advance. The differentiation amount of the quantified phase change in the electron beam due to the sample is visualized, or eventually, is integrated thereby being transformed into absolute phase change amount to be visualized.

    • A four-way switching valve device which comprises a valve chamber provided with at least a liquid inflow port and a liquid flow-direction switching means comprising a plurality of liquid inflow and outflow ports and a first valve slidably mounted on the liquid flow-direction switching means to selectively communicate one of the liquid inflow and outflow ports to a liquid outflow port respectively. A second valve is fixedly mounted on at least one end of a connecting rod extending longitudinally inside the valve chamber from the first valve and sliding hermetically inside of the valve chamber, and a thermosensitive slow acting operation device is provided at at least one end of the valve chamber and opposite to the second valve, and further, a switching device for controlling at least the inflow of the high pressure liquid into a cavity formed between the second valve and the slow acting operation device in the valve chamber is provided, the switching device being actuated directly or indirectly by a working rod of the slow acting operation device to thereby cause the high pressure liquid to flow into the cavity to move the first valve, whereby one of the plurality of liquid inflow and outflow ports in the liquid flow-direction switching means is selected to switch the communication to the liquid outflow port. The four way switching valve device of this invention has not only a simple construction but also a small size, providing a greater handling ease and reduced production costs, and therefore, can be widely used in many industrial fields. Further, the operating environment can be improved because the noise of the impulse sound generated during operation is substantially eliminated.

    • A game of skill has a support housing on which there are located a plurality of independent object transfer mechanisms preferably no two which are identical. The transfer mechanisms are aligned in a sequence such that a pathway includes a plurality of discontinuities along its length which divides it into a plurality of segments. Each of the transfer mechanisms includes one segment of the pathway and some of the transfer mechanisms can also include more than one segment. This creates a discontinuity in the pathway between each of the transfer mechanisms as well as between each segment when more than one segment is found on one transfer mechanism. Each of the transfer mechanisms includes a movable portion which is moved by the operator of the game via a control mechanism attached thereto. By manipulating the control mechanisms a spherical object can be caused to travel across the pathway. The object traverses the discontinuity in the pathway by a realignment of the segments achieved by moving the movable portion of the object transfer mechanisms.
