Abstract: PURPOSE:To enable molding with high accuracy to be achieved irrespective of nonuniformity in the temperature of a metallic mold or some variations in molding conditions, if only a mechanical working is conducted with high accuracy at room temperature, by constructing the mold by use of a specified low-expansivity metallic material. CONSTITUTION:A manifold 1 is formed of a metallic material having a coefficient of thermal expansion of not more than 5X10<-6>mm/ deg.C, in a passage for distributing a resin into a plurality of cavities 2a, 2b,... between a mold 4 and a mold 5. It is assumed that the distance from the center position of a manifold block to each of resin-ejecting port 6a, 6b,... is 400mm, and the manifold block is heated to 250 deg.C at the time of molding. Then, the positional deviation of each of the ports 6a, 6b,... between a room temperature of 20 deg.C and the molding temperature of 250 deg.C where the coefficient of thermal expansion of the metallic material is 5X10<-6>mm/ deg.C is 5X10<-6>X(250-20)X400=0.46mm, which is well contained in the range of a gate diameter, so that not any inconvenience is generated at the time of molding even under variations in the temperature of the manifold block or in the mold temperature.

Abstract: PURPOSE: To protect a metal surface from discoloration or color fading by controlling electrolytic current so as to reach current wave when electrolysis is initiated to a constant current value after said current wave draws a gently-sloping raised curve to improve an electrodeposition precipitation condition of Be or Al.  
     CONSTITUTION: In electrodepositing the hydroxide or the hydrate of Be or Al to a silver plating surface such as a character plate for a watch or the like, DC current from a rectifier 1 is branched by a condenser 3 sandwiched in parallel to an electrolyte 2 when the electrolysis is initiated. Thereby, the current passing through the electrolyte 2 is raised gently and, after a definite time, a cathodic current density is reached to the constant current value 4 to continue the cathodic electrolysis.

IPC: G11B7/2433
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To enable stable operation at the time of repetitive recording and erasing by specifying the medium reflectivity in a crystalline phase section of a recording layer prior to information recording to a specific ratio of the max. medium reflectivity value obtd. by changing the degree of crystallization or above and making the medium reflectivity value in the section higher than the medium reflectivity value in an amorphous phase section. SOLUTION: While the recording layer may be formed of material to allow a reversible structure change between an amorphous state and a crystalline state by irradiation with a laser beam, a film of a GeSbTe system is used to ensure the stable operation at the time of repetitive recording and erasing. Further, other elements may be added up to the material to max. 10 atm.% within the range of the reversible structure change and more particularly Ti, Zr, Hf, Ta and Re are added to the material in order to prevent the oxidation corrosion of the recording layer. The crystallization of the recording layer is insufficient with the medium of the crystalline phase which is obtd. under the various crystallization conditions of the recording layer and is below 90% of max. value in the medium reflectivity.  The erasure level after overwriting is fluctuated by the influence of the patterns of the previous recording and the jitter value of the regenerative signal after one time of overwriting exceeds the reference value 13% of the stable operation and, therefore, >=90% of the max. value may be obtd.
