    • A manufacturing method for a hologram which can control the formation of a ghost hologram due to a surface reflected light caused on an interface with the atmosphere is disclosed. In the first manufacturing method for a hologram by a two-beam method or a one-beam method, on an interface between a substrate having a hologram photosensitive layer and the atmosphere is disposed a quarter-wave plate, and an incident light is converted from a circularly polarized light to a P-polarized light (or an S-polarized light) through the quarter-wave plate. On the other hand, in the second manufacturing method for a hologram, a substrate, which has a hologram photosensitive layer, is fittingly held by prisms on both sides thereof. A reference light is a P-polarized light, and an angle of the reference light to a surface reflected light on an interface of the reference light is set to be approximate to a right angle. It is appropriate that a reproduced hologram is manufactured by the one-beam method by using a hologram manufactured by the above method as a master hologram.
    • 公开了一种全息图的制造方法,其可以控制由于在与大气的界面上产生的表面反射光而形成重影全息图。 在通过双光束法或单光束法的全息图的第一制造方法中,在具有全息感光层的基板与大气之间的界面上设置四分之一波长的板,并将入射光从 通过四分之一波片的圆偏振光到P偏振光(或S偏振光)。 另一方面,在全息图的第二制造方法中,具有全息图感光层的基板在其两侧由棱镜适当地保持。 参考光是P偏振光,参考光的参考光与参考光的界面上的反射光的角度被设定为接近于直角。 通过使用通过上述方法制造的全息图作为主全息图,通过单光束方法制造再现全息图是合适的。

    • An antenna switching circuit comprises a first amplifier including a first FET receiving a first receive signal from a first antenna at a gate of the first FET, and amplifying the first receive signal, and outputting the amplified signal via a drain of the first FET to an output terminal, and a second amplifier including a second FET receiving a second receive signal from a second antenna at a gate of the second FET, and amplifying the second receive signal and outputting the amplified signal via a drain of the second FET to the output terminal. The first and second FETs are coupled to receive, at their sources, first and second control signals complementary to each other so that one of the FETs is made active while the other is made inactive, depending on values of the first and second control signals. The consumption current is reduced, and in addition, an amplifier in a receiver provided to receive the output of the antenna switching circuit may be omitted.

    • A method of processing the surface of a metallic rod, wherein coating films (2, 22 and 32) are applied onto portions other than the shape where grooves are to be formed on the surface of the rod, the surfaces of the rods (1, 21 and 31) which are not coated are dissolved and processed by chemical polishing or etching, whereby patterns of very shallow grooves (6, 24 and 34) are formed on the surface of the rod, so that making of grooves on the surface of a very heavy rod, a long rod and a curved rod, which have been considered difficult by the conventional machining, can be easily and accurately carried out. Furthermore, after the making of the grooves, the surface of a rod (41) is plated in a state (42) of being coated by photoresist films and screens, whereby the grooves and the recessed portions (43) are plated (44), and thereafter, the coating films (42) are removed by buffing (45) and the like and the plated surface is finished, thus effectively plating the grooves and the recessed portions.
