Problems solved by technology

[0005] However, even if cracks cannot be seen in the container 11, after the electrode member 9 is inserted into the end closure member 12 and sealed with the bonding material 14, cracks may sometimes be seen on the pipe body 6.
At this time, the product becomes a substandard product, and there is a problem that the effective utilization rate of manufacturing decreases.

[0039] refer to Figure 5 ~ Figure 9 Instructions for the steps to make figure 1 Container 8 is shown. Specifically, 750 ppm of magnesia, 2% by weight of polyvinyl alcohol, 0.5% by weight of polyethylene glycol, and 50 parts by weight of water were added to high-purity alumina powder with a purity of 99.9% or more, pulverized by a ball mill for 1 hour, and mixed. Use a spray dryer to dry and granulate the mixture at a temperature of about 200 ° C to obtain an average particle size of about 70 μm and a static bulk density of 0.7 g / cm 3 granulated powder.

[0040] The granulated powder is at 2000kg / cm 2 Compressed under the pressure to obtain Figure 8 The shaped bodies 4, 5 are shown. At this time, in order to make the ratio (RO / RI) of the outer diameter RO of the molded body 4 of the end sealing member 7 sintered separately to the inner diameter RI of the molded body 5 of the pipe body 6 sintered alone be 1.040, the ratio of the two was adjusted. size.

[0045] According to reference Figure 5 ~ Figure 9 In the order described, the produced image 3 Container 8A is shown. Specifically, 750 ppm of magnesia, 2% by weight of polyvinyl alcohol, 0.5% by weight of polyethylene glycol, and 50 parts by weight of water were added to high-purity alumina powder with a purity of 99.9% or more, pulverized by a ball mill for 1 hour, and mixed. Use a spray dryer to dry and granulate the mixture at a temperature of about 200 ° C to obtain an average particle size of about 70 μm and a static bulk density of 0.7 g / cm 3 granulated powder.

[0046] The granulated powder is at 2000kg / cm 2 Compressed under the pressure to obtain Figure 8 The shaped bodies 4, 5 are shown. However, no recess is provided on the outer end surface of the end closure member 7A, such as image 3 As shown, a concave portion 7g is formed on the inner end surface 7e side. Both dimensions were adjusted so that the ratio (RO / RI) of the outer diameter RO of the molded b...

Abstract

The invention discloses a light-emitting container for a high-pressure discharge lamp and an end sealing part used in the container. The present invention suppresses the occurrence of cracks in a container after an electrode member is inserted into an end closure member and closed with a bonding material. The container is a light-emitting container (8) for a high-pressure discharge lamp, and has a tube body (6) forming a discharge space (10) and an end closing member (7) for closing the end of the tube body (6). The container (8) is formed by sintering the assembled body of the sintered body of the pipe body (6) and the sintered body (7) of the end closure member. The end closing member (7) has an outer end surface (7f), an inner end surface (7e) facing the discharge space (10), and an electrode member insertion hole (7d) provided between the outer end surface (7f) and the inner end surface (7e). ). A concave portion (7c) is formed on at least one of the outer end surface (7f) and the inner end surface (7e).

Description

technical field [0001] The invention relates to a luminescent vessel for a high-pressure discharge lamp and an end closure for the vessel. Background technique [0002] In the light-emitting container for high-pressure discharge lamps described in Japanese Patent Document 1 (Japanese Unexamined Patent Publication No. 10-125230), the molded body of the tube body and the molded body of the ring-shaped end sealing member are produced separately, and the two molded bodies are Assembled into an assembly. Then, the assembled body is sintered to manufacture a container for enclosing the metal halide. At this time, the sintering shrinkage ratios of both are set so that the outer shape when the molded body of the end closure member is sintered alone is larger than the inner diameter when the molded body of the pipe body is sintered alone. In this way, during sintering, since the pressure-bonding force is applied from the pipe main body to the end sealing member, the joining of both...
