    • PROBLEM TO BE SOLVED: To provide an apparatus for safely and rapidly melting a syringe needle, which solves the following problem that a dangerous situation occurs by the generation of an ultraviolet ray by sparks and arc when a syringe needle is melted with a current. SOLUTION: When the syringe needle is inserted from the conical hole of an upper electrode, the upper electrode and a lower electrode is short-circuited, so as to melt the needle by Joule heat. A syringe needle melter includes a circuit for allowing the current to intermittently flow when the current is enlarged by a battery and a protecting circuit between both the electrodes. Since the needle is inserted from the conical hole in the upper electrode, the electrodes have a structure to prevent the sparks and the UV ray from leaking outside. A spring is arranged in the lower part of the upper electrode, so that the upper electrode is vertically moved. Thus, melt is performed even to the base of the syringe needle.

    • 要解决的问题:提供一种用于安全和快速地熔化注射器针的装置,其解决了当注射针被熔化时由于通过火花和电弧产生紫外线而发生危险情况的以下问题 当前。 解决方案:当注射器针从上电极的锥形孔插入时,上电极和下电极短路,以便通过焦耳热来熔化针头。 注射器针胶机包括用于当电流被电池放大并且在两个电极之间的保护电路时允许电流间歇地流动的电路。 由于针从上部电极的锥形孔插入,电极具有防止火花和紫外线泄漏到外部的结构。 上部电极的下部设有弹簧,使上部电极垂直移动。 因此,甚至对注射器针头的基部进行熔融。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a signal of which the lighting can be clearly detected by preventing a reflection by a signal light, since the reflection and a pseudo lighting by the signal light of a traffic signal due to direct sunlight in mornings or evenings cause not only drivers but also pedestrians to falsely recognize and thus increase a possibility of a traffic accident. SOLUTION: To block the direct sunlight entering the signal light of the traffic signal and thus prevent a reflection, antireflection inclined planes to which nonreflective painting is applied and transmission inclined planes passing the light of the traffic signal are combined in a mountain shape to form an antireflection plate arranged in a row in elongated stripe-like forms parallel to one another. The antireflection plate is attached to the front surface of the signal light to prevent a pseudo lighting. Silver mirror painting is applied to the back surface of the antireflection inclined plane for effective irradiation of the light. The antireflection inclined plane is inclined at nearly an elevation angle of a person looking at the signal so that the non- transmission plane does not interfere with the person confirming the signal. Two kinds of the transmission inclined planes are selectively used according to applications: one is formed with thin oblong transparent semicolumnar surfaces arranged in stripe- like forms to diffuse and irradiate the light and the other is formed with oblong transparent inclined surfaces.
