摘要： PROBLEM TO BE SOLVED: To facilitate transportation, transfer and handling of a panel member and a spacer and to simplify assembly work of a flat panel display, while realizing sufficient thinning and light-weight of the flat panel display.
SOLUTION: Either one or both of the front side panel member 1 and a back side panel member 2 that form a vacuum gap part 5 between each of them are formed as a single component having a spacer 6 on inner face. As a means of installing the spacer 6, a printing process, a press molding process, an etching process, or a blast process are adopted. The spacer 6 is formed as a plurality of columnar bodies or as lattice like. The spacers are formed as separate and individual bodies and are constructed by a single member on all the region of the vacuum gap part.

摘要： PROBLEM TO BE SOLVED: To provide a glass funnel for a cathode ray tube having light weight and ensuring strength enough to endure breakage caused by vacuum stress when a cathode-ray tube is constituted.
SOLUTION: A thickness S of a seal edge face 3c1 of a funnel 3 is set to be almost equal to a thickness S' of a seal edge face 2b1 of a funnel 2. A body part 3e of the funnel 3 has a first region 3e1 having a given dimension in a direction parallel to a tube shaft Z from the seal edge face 3c1 and a second region 3e2 except the first region. The thickness of the second region 3e2 is relatively smaller than that of the first region 3e1, and a boundary part of both regions forms a step 3e3 on the outer surface of the body part 3e.

摘要： PROBLEM TO BE SOLVED: To provide a glass panel for a cathode-ray tube, securing a fixed pressure-resisting strength of a cathode-ray tube as manufactured, and not causing a fracture when inner surfaces of blend roundness parts are flawed or sealed with frit. SOLUTION: This glass panel 1 for a cathode-ray tube is made up of a substantially rectangular face part 2 equipped with an effective screen part 2a on which an image is projected and sidewall parts 3 substantially vertically extending from peripheral edges of the face part 2. A compression stress layer is formed on each other surface, at least, of the face part 2 and of the sidewall parts 3. The maximum compression stress value σCM of the compression stress layers measured in an area 2c of the peripheral edges of the face part 2 and a tensile stress value σTR produced in inner surfaces 4a of blend roundness parts 4 where end parts 2b of the effective screen part 2a in diagonal axis directions of the face part 2 are jointed to the sidewall parts 3, have a relation of σTR

摘要： PROBLEM TO BE SOLVED: To achieve a lighter weight and maintain strength against vacuum breakage. SOLUTION: A thickness S of a seal edge face 3c1 of a funnel 3 is set to be almost equal to a thickness S' of a seal edge face 2b1 of a panel 2. A body portion 3e of the funnel 3 has a first region 3e1 with its size h ranging from the seal edge face 3c1 to a direction parallel to a tube axis Z and a second region 3e2 except the first region 3e1, in a range excluding a corner portion 3a3. The thickness of the second region 3e2 is relatively smaller than the thickness of the first region 3e1. As a result, a boundary between both regions forms a stepped portion 3e3 on the outer face of the body portion 3e.

摘要： PURPOSE:To reduce cracks of glass containers without prolonging heat treatment time in producing glass containers by evacuating the interior while heating by controlling glass containers under specific pressure during rise and drop in temperature. CONSTITUTION:In producing a container consisting at least partially of glass such as telereceiver by evacuating the interior while heating, atmospheric pressure or higher than the atmospheric pressure is applied to the outside of the container during temperature rise in heating to suppress tension occurring in the inner face. Pressure applied to the outside of the container is reduced during temperature dropping in such a way that pressure difference between pressure at the outside of the container and pressure at the inner side is reduced so that stress resulting from pressure difference between the outside and inside is not produced to reduce tension occurring at the outside.
