摘要： A light dispersion equalizer for compensating for variation in propagation rate among employed wavelengths. On a substrate having a groove for mounting an optical fiber provided thereon, heaters are formed side by side in parallel with the optical fiber mounting groove, and the optical fiber is accommodated in the groove. Because distance between the optical fiber and the heaters can be fixed, positioning of the optical fiber with the heaters can be performed with high accuracy.

摘要： An electron tube cathode comprises a base (1) formed mainly of nickel, an alloy layer (4) disposed on the base (1) and including nickel and tungsten having a grain size smaller than that of the base, and an electron emissive material layer (5) deposited on the alloy layer, and including an oxide (6) of an alkaline-earth metal containing at least barium, and a rare earth metal oxide (7) of 0.01 to 25 weight percent and containing at least one of scandium oxide and yttrium oxide. The cathode has a life characteristics improved compared with the prior art, even if operated with a current density of 3 A/cm 2 or more.
摘要翻译：电子管阴极包括主要由镍形成的基体（1），设置在基体（1）上的合金层（4），并且包括具有小于基体的晶粒尺寸的镍和钨以及电子发射材料层（5），并且包含至少含有钡的碱土金属的氧化物（6）和0.01至25重量％的稀土金属氧化物（7），并且包含至少一种氧化钪和氧化钇。即使以3A / cm 2以上的电流密度进行操作，与现有技术相比，阴极的寿命特性得到改善。
