摘要： PROBLEM TO BE SOLVED: To enable manufacturing of plural vacuum air tight container simultaneously in mass production by forming plural exhaust holes for a first multiple substrate, and surface-sticking a second multiple substrates thereto and cutting it. SOLUTION: Plural exhaust holes 6 are formed for plural field emission cathodes formed on a first multiple substrate 2'. A column is formed on either the first multiple substrate 2' or a second multiple substrate 3', a sealing member 8 is applied, and the first multiple substrate 2' and the second multiple substrate 3' are surface-sticked each other. A getter box provided with an exhaust tube 5 is placed at an exhaust hole 6 formed on the first multiple substrate 2'. A sealing member 8 is heated and fused, and the first multiple substrate 2' and the second multiple substrate 3' are sealed each other. Next, plural vacuum air tight containers 1 are separated by cutting. Air is exhausted from an exhaust tube 5 provided with each vacuum air tight container 1 whose inside is evacuated, and an exhaust tube 5 is sealed.

摘要： PROBLEM TO BE SOLVED: To provide a support tool holding a getter in a vacuum container and having a simple structure. SOLUTION: This getter support tool 30 is provided with a hold section 32 pinching a getter 1 from above and below, the first support leg 34 protruded toward the lower face of the getter 1 integrally with the hold section 32, and the second support leg 35 having a spring property and faced to the upper face of the getter 1 integrally with the hold section 32. The hold section 32 of the getter support tool 30 holds the getter 1 from the outside. The getter 1 fitted to the getter support tool 30 is stored in the getter chamber 20 of a display tube 10. The upper face of the getter 1 emitting a getter material 3 is faced to the outer face of the second substrate 13, and a getter film is formed on the outer face of the second substrate 13. The getter support tool 30 is pressed by the elasticity of the second support leg 35 and fixed. The warp of the second support leg 35 is changed in response to the contact state with the second substrate 13 of an envelope 11. The distance between the upper face of the getter 1 and the second substrate 13 of the envelope 11 is made constant, and the interval between the getter 1 and the second substrate 13 is kept at the desired value.

摘要： PURPOSE: To provide a sheet glass cutter capable of cracking sheet glass having a width small relative to a thickness without any trouble and dealing with a fluctuation in the thickness. CONSTITUTION: A glass substrate 10 is placed on a pair of horizontal holding tables 4, 4 installed apart a spacing and is held on the holding surfaces 4a of these holding tables by attraction means. A cutter 3 forms a groove 10a of a straight line on the rear surface of the glass substrate 10. A pair of the holding tables 4, 4 supported by link mechanisms 5a, 5b are moved to a high position on the outer side from a horizontal state by driving cylinders. The respective holding tables 4, 4 rotate upward around the groove 10a within the plane orthogonal with the longitudinal direction of the groove 10a. The glass substrate 10 is kept held by the respective holding table 4, 4 and is, therefore, cracked along the groove 10a.
