摘要： PURPOSE:To improve lamp starting and a maintainance rate of a flux of light by making an alumina coating quantity of an alumina film of a lamp glass tube to be a fixed quantity while making average resistance value of a conductive film in the central part of a glass tube to be the prescribed value. CONSTITUTION:An alumina protective film 3 is applied on a transparent conductive film 2 formed inside a lamp glass tube 1. As an alumina application liquid, alumina powder having the grain diameter not exceeding 50mum is suspended in a pure water for being well dispersed, while a proper quantity of surface activator is added and said liquid is poured into from the top of the glass tube 1 for being dried. Then, the alumina coating quantity is made to be 0.05-0.12mg/ cm . Further, the average resistance value of the conductive film in the central part except both end parts of the glass tube 1 is made to be 0.05-0.35kOMEGA/cm. Thereby, discharge starting voltage at a low temperature is lowered for improving starting while improving a maintainance rate of a flux of light.

摘要： PURPOSE:To solve a problem of interwinding of filaments each other, reduce the rate of fault and shorten a process of work by cutting a linear filament after tying it. CONSTITUTION:A linear filament 2 has a construction wherein a fine tungsten line 5 is loosely wound round a tungsten core 4. This is finished, being continuously wound in a spool form with no cutting while being cut after being tied to a stem. That is, firstly, as shown in Fig. (a), the linear filament 2 is tied to the stem 6. Next, as shown in Fig. (b), the filament 2 is cut in a fixed position in a short time by a laser beam radiation device 7. In this way, mounts 8 shown in Fig. (c) are manufactured in turn.
摘要翻译：目的：解决灯丝相互缠绕的问题，通过在捆扎后切割线状丝来降低断层率，缩短工作过程。构成：线状丝2具有细钨线5松散地缠绕在钨芯4周围的结构。这被完成，在被连接到杆上之后被切割而连续地卷绕成卷轴形式而不切割。也就是说，首先，如图1所示。（a）中，将线状丝2连接到杆6上。（b）所示，通过激光束照射装置7将灯丝2在短时间内固定在固定位置。（c）依次制造。

摘要： PURPOSE:To sinter the whole fluorescent body at a time and reduce its fabrication time by coating and drying a fluorescent body on the whole surface and an antireflection fluorescent body on part of this fluorescent body without sintering it when a reflection type fluorescent lamp is fabricated. CONSTITUTION:A conventional fluorescent body suspension is coated on a whole interior surface of a glass tube 1 of an antireflection fluorescent lamp and the first fluorescent body layer 4 is formed. Then, the first fluorescent body layer 4 is formed. Then, the first fluorescent body layer 4 is dried in a atmosphere at 20- 100 deg.C. The second fluorescent body layer 5 is coated on part of this unsintered fluorescent body layer 4 and the fluorescent body layer 5 is dried. Finally the fluorescent body layers 4 and 5 are sintered in a sintering furnace. Since the fluorescent body layer 5 functions as an antireflection layer, the illuminance immediately under the fluorescent lamp can considerably be increased.
