    • In conventional self-lighting type push-button input devices there is adopted a construction wherein push-button portions and a base plate are formed using the same material. Since a light conducting function cannot be expected of the base plate, it is necessary to provide the same number of lamps as the number of push-button portions, with consequent increase of size and cost. In a self-lighting type push-button input device according to the present invention, a button base portion can be formed of a transparent material, holes can be formed in predetermined positions of the button base portion, and spring portions can be formed integrally with the holes by molding with use of transparent silicone rubber with a light diffusing agent incorporated therein. With this construction, the button base portion 2 serves as a light conducting portion able to effect the propagation of light without causing any loss, and the spring portions can uniformly diffuse the light distributed thereto by the light conducting portion, whereby lighting can be effected by a reduced number of light sources, that is, the reduction of size and cost can be attained to solve conventional problems.
    • 在传统的自发式按钮输入装置中,采用了使用相同材料形成按钮部分和基板的结构。 由于不能期待基板的导光功能,因此需要提供与按钮部分数量相同数量的灯,从而随之增加尺寸和成本。 在根据本发明的自发光型按钮输入装置中,按钮基部可以由透明材料形成,孔可以形成在按钮基部的预定位置,弹簧部可以与 通过使用其中结合有光漫射剂的透明硅橡胶成型而形成孔。 通过这种结构,按钮基部2用作能够实​​现光的传播而不造成损失的导光部,并且弹簧部能够均匀地漫射由导光部分分配到其上的光,由此可以通过 可以实现减少光源数量,即尺寸和成本的降低以解决常规问题。

    • In the reaction of catalytic gas phase oxidation by means of a shell-and-tube type reactor adapted to circulate a heating medium to the shell of the reactor through the medium of a circulation device connecting an annular conduit connected thereto, a method for the catalytic gas phase oxidation characterized by subjecting a part of the heating medium extracted from the shell of the reactor to heat exchange, introducing the heating medium resulting from the heat exchange into the proximity of a heating medium circulation inlet on the inlet side of the circulation device or the annular conduit on the outlet side of the reactor. The flow rate of the heating medium after the heat exchange is preferred to be in the range of 2-40 vol. % based on the flow rate of the heating medium within the shell of the reactor and the temperature difference of the heating medium at the inlet and the outlet to be in the range of 15-150° C. According to this invention, it is made possible to reduce evenly the hot spots in the reaction tubes, improve the yield of the product aimed at, and implement a reaction of catalytic gas phase oxidation of propylene or isobutylene.
