Title: Surface treatment method for electrode parts of cathode-ray tube
Inventor: WATANABE TETSUYA
IPC: H01J9/00
Filed: 1987-05-27
Abstract: PURPOSE:To obtain oxidated films having desired radiation factors for both cases of Fe material and Ni-Fe material subjected to surface treatment by means of the same treatment furnace by setting the grade of replacing the oxidating environment in the case of Fe material smaller than that in the case of Ni-Fe material. CONSTITUTION:A flat mask formed with Fe material and another flat mask formed with Ni-Fe material are annealed at about 900 deg.C and about 1000 deg.C respectively and press-molded after being subjected to straightening and then, a blackening process for forming black rust is applied to the surfaces of those formed shadow masks 6. For instance, if steam is fed in a furnace 1 at about 0.14m<3>/min flow rate and maintained at about 560 deg.C for 30 minutes after the inner pressure of the furnace 1 is set to about 200mmAq, black rust with 0.75 radiation factor can be obtained in the case of Fe material. If the inner pressure inside a container 2 is set lower than that in the case of Fe material, so as to set a higher grade of replacement of the oxidating environment inside the container 2, in the case of Ni-Fe material, an oxidated film with the desired radiation factor 0.33 or more can be obtained. Thus, oxidated films having desired radiation factors can be obtained when oxidated films are formed on both Fe material and Ni-Fe material by means of the same treatment furnace.

Filed: 1990-05-24
Abstract: PURPOSE:To obtain superior printing performance and to stick the label on a base at extremely low heat seal temperature by forming a heat adhesive resin layer by incorporating a constant amount of plasticizer in ethylene-based resin whose ethylene content is specified. CONSTITUTION:The label is formed basically of at least >=2-layered structure of a base material layer where a print is made and the heat-sensitive adhesive layer. Then the ethylene-based resin which contains >=50 wt.% ethylene is used for the low-fusion-point heat-sensitive adhesive resin layer stuck on the base material layer and a 0.5 - 8 wt.% plasticizer is incorporated in the ethylene- based resin. Consequently, while excellent printing performance such as paper feeding performance and ink adhesive strength are maintained, low-temperature heat sealing with high adhesive strength is possible and high-speed heat sealing and integral molding (in-mold formation) are enabled.

Title: Outboard engine
Inventor: YAMAMOTO YOJI
IPC: F01P3/20
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To effectively suppress oil temperature rise by providing an engine mount member with a water down passage positioned on the outside of an oil pan connection face so as to make cooling water after passing a thermostat valve, flow down, and a cooling water lead-out means positioned below the water down passage so as to lead out the cooling water to the periphery of an oil pan. SOLUTION: Cooling water fed to an engine E is led to a water down passage 45 from a cooling water passage 39 after cooling an engine body and further fed to a cooling water reservoir 55 formed between an engine mount member 6 and a gasket. Lubricating oil of relatively high temperature returned to an oil pan 21 from the engine E is thereby cooled by the engine mount member 6 on the way. Excessive temperature rise of the engine mount member 6 caused by exhaust gas flowing in an exhaust passage 47 is avoided by a water up passage 44, and cooling water in the cooling water reservoir 55 falls over a large range around the oil pan 21 from a plurality of holes 56 provided in the gasket 27. The oil pan 21 itself is thereby cooled.
