摘要： A helium-cadmium ion laser is disclosed which has a tubular housing hermetically closed at both ends by Brewster windows and having a hollow cathode mounted therein. Disposed outside the hollow cathode and open to its interior are a row of primary anodes and a row of metal chambers containing a metal material to be vaporized. A pair of secondary anodes are further disposed adjacent the opposite ends of the hollow cathode for protecting the Brewster windows from contamination by the metal vapor by sending it back into the hollow cathode. In order to prevent the metal vapor from depositing on the ends of the hollow cathode on being thus sent back, a pair of tubular insulators are coaxially mounted next to the opposite ends of the hollow cathode for the passage of the metal vapor therethrough. Each tubular insulator has a bore including a smaller diameter portion away from the hollow cathode, and a larger diameter portion closer to the hollow cathode. Further, for impeding the flow of the metal vapor from the hollow cathode toward the Brewster windows, the laser housing has a pair of constrictions adjacent the Brewster windows.
摘要翻译：公开了一种氦 - 镉离子激光器，其具有通过布鲁斯特窗口在两端密封并具有安装在其中的中空阴极的管状外壳。设置在空心阴极外面并向其内部开放的是一排主阳极和一排含有要蒸发的金属材料的金属室。一对次级阳极进一步设置在中空阴极的相对端附近，用于通过将布鲁斯特窗口送回中空阴极来保护布鲁斯特窗口免受金属蒸气的污染。为了防止金属蒸气沉积在中空阴极的端部上，因此这样一个管状的绝缘体被同轴地安装在中空阴极的相对端上，以使金属蒸汽通过。每个管状绝缘体具有包括远离空心阴极的较小直径部分的孔和更接近空心阴极的较大直径部分。此外，为了阻止金属蒸气从中空阴极朝向布鲁斯特窗口流动，激光器壳体具有与布鲁斯特窗口相邻的一对收缩部。

摘要： A He-Cd ion laser of the type having a series of anodes open to the interior of a hollow cathode, a series of metal chambers containing a supply of Cd to be vaporized, and a heater for heating the metal chambers for vaporizing the Cd supply. For holding constant the Cd vapor pressure within the hollow cathode and, in consequence, the intensity of the output beam, an electric control system is provided which comprises a constant current regulator connected to each anode for supplying a constant current thereto, and a heater control circuit for controlling the magnitude of a current fed to the metal chamber heater so as to hold the output voltage of each constant current regulator equal to a reference voltage.

摘要： A rectangular opening/closing bar is formed, which is inserted in the curl ring of the ring binder to bind papers. The tip end of the opening/closing bar 28A is provided with an instruction portion 28a to raise and open ring pieces in turn while inserting the opening/closing bar 28A. Further, the opening/closing bar may have swollen portions on both ends of the opening/closing bar 28A to enable the bar slide smoothly in the curl ring. And it may be provided with a guide plate 28D perpendicular to the side wall 28b of the opening/closing bar 28A of the swollen portions side. In order to enhance the workability of the opening/closing bar, it may be preferable to use an auxiliary device for positioning the ring binder.
