    • The invention provides a low temperature probe having a high sensitivity by reducing a heat intrusion into a receive coil. A heat making an intrusion into a coil is suppressed by inserting a heat radiation shield in which a temperature is controlled at about 100 K to a portion between an outer container of a probe and a coil portion. A heat radiation shield bore sleeve is provided in a heat radiation bore, is connected to the heat radiation shield, and is cooled by a second heat exchanger. Further, the coil portion is cooled by a first heat exchanger. In preparation for a contraction at a time of being cooled, the outer container, the heat radiation shield and the coil portion are connected by using a fixing portion, and a heat relieving mechanism or a contraction relieving mechanism is provided in a root side (an opposite side to the fixing portion) of the heat radiation shield and the coil portion. The fixing portion is formed in a shape and made of a material having a small heat intrusion amount and having a small heat contraction.
    • 本发明通过减少对接收线圈的热侵入来提供具有高灵敏度的低温探针。 通过将温度控制在约100K的热辐射屏蔽物插入到探针的外部容器与线圈部分之间的部分来抑制进入线圈的热量。 热辐射屏蔽孔套筒设置在散热孔中,连接到散热屏蔽,并由第二热交换器冷却。 此外,线圈部分由第一热交换器冷却。 为了准备冷却时的收缩,通过使用固定部连接外容器,散热屏蔽体和线圈部,并且在根侧设置有放热机构或收缩解除机构 热辐射屏蔽体和线圈部分相对于固定部分的相对侧)。 固定部形成为由热侵入量小且热收缩小的材料构成。

    • In an ultrahigh sensitive NMR apparatus, a stability of a temperature of a very low temperature probe coil is improved. A low temperature probe of the high sensitive NMR apparatus is structured at a very low temperature by a cooling apparatus. A cooling medium at a room temperature (300 K) discharged from a compressor is cooled down to 70K by a countercurrent heat exchanger, and is next cooled down to 4K or less by a series of second stages. Further, the cooling medium enters into a low temperature probe via a transfer tube, cools a probe coil to 5 to 10K by a heat exchanging portion, further cools a radiation shield to 40 to 60K, and makes a circuit via the countercurrent heat exchanger. A high temperature stability can be applied to a receiving probe coil in the low temperature probe by a cooling apparatus having a high temperature stability.
    • 在超高灵敏度的NMR装置中,提高了极低温度的探针线圈的温度的稳定性。 高灵敏度NMR装置的低温探针通过冷却装置在非常低的温度下构成。 从压缩机排出的室温(300K)的冷却介质通过逆流式热交换器冷却至70K,接着通过一系列的第二级冷却至4K以下。 此外,冷却介质通过传输管进入低温探针,通过热交换部将探针线圈冷却至5〜10K,进一步将辐射屏蔽体冷却至40〜60K,并通过逆流热交换器进行回路。 可以通过具有高温度稳定性的冷却装置对低温探针中的接收探针线圈施加高温稳定性。

    • There is disclosed a method of fixedly mounting a graded-index rod lens to a holder easily with high reliability without requiring machining of one end face of the rod lens which is difficult to achieve if the lens has a small diameter. The present invention also offers an optical component having the graded-index rod lens inserted and fixed in a through hole formed in the holder. A part of the through hole on the side of one end face of the rod lens is formed as a tapering hole. A transparent member is molded so as to be tightly fitted with the holder such that the whole end face of the lens and at least a part of the inner surface of the tapering hole are covered with the transparent member. A part of the surface of the transparent member is shaped spherically or aspherically to form a molded lens.
    • 公开了一种将渐变折射率棒状透镜固定地安装到保持器上的方法,其可靠性高,而不需要加工棒状透镜的一个端面,如果透镜具有小直径则难以实现。 本发明还提供了一种光学部件,其具有插入并固定在形成在保持器中的通孔中的渐变折射杆透镜。 杆透镜的一个端面侧的通孔的一部分形成为锥形孔。 透明构件被模制以与保持件紧密配合,使得透镜的整个端面和锥形孔的内表面的至少一部分被透明构件覆盖。 透明构件的表面的一部分被球形或非球面成形以形成模制透镜。
