Title: Method for coloring cement product
Inventor: MINEMOTO TAKASHI
IPC: C04B41/63
Filed: 1990-10-29
Abstract: PURPOSE:To obtain a colored cement product, capable of stacking thereof just after coating and excellent in also water resistance and durability after hardening by feeding a powdery material containing a powder coating, composed of a thermoplastic resin and added to cement onto the surface of a cement product and curing the resultant product under specific conditions. CONSTITUTION:A powdery material containing 3-100 pts. powder coating, composed of a thermoplastic resin and added to 100 pts. cement is fed onto the surface of a cement product and water required to carry out hydrating reaction of cement is added. The resultant coated product is then cured in an autoclave under temperature conditions above the melting point of the powder coating to color the cement product. The reason why the powder coating is added in an amount of 3-100 pts. is as follows. If the amount thereof is smaller than 3 pts., required water resistance cannot be imparted to films and sufficient coloring cannot be performed. If the amount is larger than 100 pts., the amount of the blended cement is reduced in inverse proportion thereto and the film strength is deteriorated.

Abstract: PURPOSE:To enable high-frequency drive, and to increase capacity by controlling the degree of opening and closing of a solenoid valve on the basis of pressure on a compressor when a gaseous refrigerant is returned and moved and adjusting the speed of pressure fluctuation in a pulse tube. CONSTITUTION:The degree of opening and closing of a solenoid valve 24 is automatically adjusted on the basis of the pressure of a compressor 9, and a proper quantity of a gaseous refrigerant is bypassed through the solenoid valve 24 and returned directly to the compressor 9. Consequently, the speed of return is increased only by the direct return section of the gaseous refrigerant, and the high-frequency driving of a cryogenic refrigerator is enabled while the quantity of an adiabatic expansion refrigerant in a pulse tube 17 can also be ensured properly. As a result, the period and high-low pressure ratio of the cryogenic refrigerator are controlled under an optimum state by balancing the speed of the returned refrigerator and the quantity of adiabatic expansion, and a program is constituted so that refrigerating capacity is increased. That is, when the solenoid valve 24 is closed and the speed of pressure drop in the compressor is too fast, the insufficient speed of return of the refrigerant is decided, and a solenoid valve 25 is adjusted automatically in the direction of the increase of the degree of opening and closing.

Filed: 1988-11-21
Abstract: PURPOSE: To dispense with extra after machining for improving surface accuracy by setting the shank of a tool being rotated transversely to the feed direction and designing the end face of the tool to adapt to the surface inclinations of the tool having an inclination to the surface of a workpiece at right angles to the feed direction. CONSTITUTION: A workpiece having a concave section is subjected to end milling that acquires a linear contact portion 5, in which the end face 10 of a tool 1 is somewhat conically machined for obtaining such a linear contact portion 5 and the tool 1 has an inclination or cone angle α to the side of the workpiece. Though the cutter shank is held substantially perpendicularly to a feed direction 7 and the linear contact portion 5 is limited only in the range corresponding to half the cutter diameter D, such linear contact may be obtained over the cutter diameter D so that a workpiece is machined to have a concave of a radius of curvature of ρ.  The minimal possible radius of curvature of a concave-machined surface is obtained, for a cylindrical workpiece, from the axial projection drawing of the workpiece in the end face figuration and is defined by ρmin =D/(2.sin α). This machining offers improved surface accuracy of the workpiece.
