    • The iron core characteristics of an amorphous iron core transformer degrade significantly when machining from material into a transformer. This phenomenon is suppressed to improve the iron core characteristics of the finished transformer products. In the present invention, an insulating thin film is formed in at least one side of an amorphous ribbon, and is formed in at least one for each plurality of amorphous ribbons of iron core material. Moreover, in the surface of the amorphous ribbon that is the iron core material of the amorphous iron core transformer, silane or the like is vapor deposited to form an insulating thin film, the insulating thin film being formed in the thickness of approximately 1 μm. With such structure, an increase in eddy current loss occurring when machining from the material into a transformer is suppressed to reduce no-load loss of the transformer.
    • 当从材料加工成变压器时,非晶铁芯变压器的铁芯特性显着降低。 这种现象被抑制,以提高成品变压器产品的铁芯特性。 在本发明中,绝缘薄膜形成在无定形带的至少一侧,并且形成在铁心材料的多个非晶带中的至少一个中。 此外,在作为非晶铁芯变压器的铁芯材料的非晶质带的表面中,蒸镀硅烷等以形成绝缘薄膜,绝缘薄膜形成为约1μm的厚度。 通过这样的结构,抑制了从材料加工成变压器时发生的涡流损耗的增加,以减小变压器的空载损耗。

    • There are provided a directional communication apparatus whose low power consumption is realized, a communication system using this apparatus, a directional communication apparatus where time up to establishment of communication after restart of the communication is shortened, and a communication system using this apparatus.The directional communication apparatus has an antenna capable of controlling a directional characteristic, an information storage section which stores communication history for specifying communication conditions at the time of communication, and a control section which controls the antenna based on the communication history so that the antenna can communicate with a destination device recorded in the communication history. The directional communication apparatus calculates a movement vector based on the communication history, estimates a moved position of the destination device, and estimates communication conditions optimum for communication so as to restart the communication.
