To provide a rain water, snow, frost, or hail attachment prevention method for inexpensively preventing rain water, snow, frost, or hail or the like from freezing by attachment to a light emission surface of a traffic light or a pilot lamp or attachment to an outer side or the like of a sensor window in various kinds of on-vehicle sensors or the like, or preventing dew condensation.SOLUTION: A chip resistor 16 is used as a heat generation source. The chip resistor 16 is a basic component to be frequently used in a circuit of every electric and electronic apparatus and also to be inexpensively obtained on the market as a general-purpose article. The chip resistor 16 provides a stable heat generation amount and can be used in AC and DC, so as to facilitate circuit design. Besides, the chip resistor 16 is compact. Such a compact chip resistor 16 that can be inexpensively installed in a small apparatus is exclusively used as a heat generation source to heat an attachment prevention object such as a traffic light 10, so as to inexpensively prevent freezing on the attachment prevention object 10.SELECTED DRAWING: Figure 2
【課題】低コストで雨水、雪又は霜若しくは霙等が信号機や表示灯の発光面や、各種車載センサ等のセンサ窓の外側等に付着して氷結し、又は結露が生ずるのを防止できる雨水、雪、霜又は霙の付着防止方法を提供すること。【解決手段】発熱源としてチップ抵抗器16を用いる。チップ抵抗器16はありとあらゆる電気・電子機器の回路に数多く使われる基本的な部品であり、汎用品として市場で安価に入手できる。また、チップ抵抗器16は安定した発熱量があり、交流でも直流でも使えるので回路設計が容易である。さらにまた、チップ抵抗器16は小型である。この安価で小さな機器に設置できる小型のチップ抵抗器16を信号機10等の付着防止対象物を加熱する発熱源として専ら用いることにより、低コストで付着防止対象物10の氷結を防止する。【選択図】図2
