摘要： This invention relates to a method for the formation of a thin MgF2 film characterized by applying solution containing a Mg salt and a BF3 complex salt onto a substrate and then heating to form a thin MgF2 film. The method of the invention can afford a transparent thin MgF2 film having high durability and low refractive index on a substrate such as a glass sheet and an optical component, and on the surface of a substrate such as CRT and a liquid crystal display panel, and is useful for forming a low-reflection film.

摘要： This invention relates to a method for producing a polyether comprising conducting ring-opening addition reaction between a hydroxyl-containing initiator and a number of monoepoxide molecules each having at least three carbon atoms, particularly alkylene oxide molecules, in the presence of a composite metal cyanide complex as a catalyst, treating the formed polyether containing the catalyst with a treatment comprising an alkali metal alcoholate to thereby deactivate the catalyst, and removing the deactivated catalyst and the remaining treatment from the polyether. The invention also relates to a method for producing a polyether comprising deactivating the catalyst with the treatment, reacting the formed polyether with ethylene oxide, and removing the deactivated catalyst and the remaining treatment from the polyether. The use of the treatment comprising an alkali metal alcoholate facilitates the removal of the composite metal cyanide complex from the polyether and the production of oxyethylene-terminated polyether.

摘要： This invention relates to a numerically controlled chamfering apparatus used to chamfer and grind the peripheral portions of a glass plate, such as a window glass for an automobile. An object of this invention is to chamfer a glass plate at a predetermined rate at all times in accordance with the variations in the grinding capacity of a chamfering wheel used for chamfering a corner portion of a glass plate. This invention is directed to a numerically controlled chamfering apparatus for glass plates, consisting of a mechanism for transferring a chamfering head (58) with chains (42), (62) on a horizontal plane in the direction of X-axis and the direction of Y-axis which crosses the direction of X-axis at right angles thereto, a swing mechanism composed of a rotary disc provided in the chamfering head, a pressure applying mechanism slidingly supporting the chamfering wheel in the direction of a normal to a periphery of the glass plate with respect to the disc, and adapted to move the chamfering wheel forward and backward, and a control unit for regulating the quantity of the forward and backward movements of the chamfering wheel. This apparatus is capable of chamfering a glass plate at a predetermined rate even when the shape of the glass plate and the diameter of the chamfering wheel vary.
摘要翻译：本发明涉及一种数控倒角装置，用于倒角和研磨诸如汽车用窗玻璃的玻璃板的周边部分。本发明的目的是根据用于倒角玻璃板的角部的倒角轮的研磨能力的变化，始终以预定的速率倒角玻璃板。本发明涉及一种用于玻璃板的数控倒角装置，包括用于在水平面上沿X轴方向传送具有链条（42），（62）的倒角头（58）和/ Y轴，其与X轴的方向成直角地交叉，由设置在倒角头中的旋转盘构成的摆动机构，将倒角轮沿着垂直方向垂直方向玻璃板相对于盘，并且适于使倒角轮向前和向后移动;以及控制单元，用于调节倒角轮的向前和向后运动的量。即使当玻璃板的形状和倒角轮的直径变化时，该装置能够以预定的速率倒角玻璃板。
