It is an object of the present invention to provide a coloration, which does not damage a contact lens and is not discolored, and to provide an improved technique of manufacturing a contact lens, wherein the contact lens can be marked at the same time as the polymerization of the contact lens in the mold, without troublesome processes. In the present invention, there is adopted, as a coloring composition, a medium which comprises: at least one of monomer components, which constitutes a monomer composition to provide a polymer to form the contact lens; and a predetermined dyestuff. A concave molding surface (28) is roughened by forming a multiplicity of minute recesses by sputtering, before attaching the coloring composition to the concave molding surface; and coloring composition attached to the concave surface (28) is prepolymerized, before the introduction of the monomer mixture to the concave molding surface.

A vacuum lamination apparatus for performing a vacuum lamination process on a lamination material includes a base plate having two opposing sides for placing the lamination material; and evacuation members having an approximately triangular cross-section and fixed hermetically to the base plate at the two opposing sides. Each of the evacuation members has an evacuation port with a constant distance relative to the base plate. The vacuum lamination apparatus also includes end plates fixed hermetically to ends of each of the evacuation member, and a cover sheet placed on the base plate for covering the lamination material and the evacuation members to form a lamination space for performing the vacuum lamination process.

A combination vessel is capable of carrying out temporary fastening while always bringing down a ring portion subsequently to breakage of a bridge part during an opening operation. A cap portion and a ring portion of a cap type sealing tool are coupled to each other through a bridge part. Through breakage of the bridge part during opening of the cap portion, the ring portion is pulled down while a sliding protrusion on an internal wall in a lower stage area of the ring portion always contacts by pressure an upward spread zone on an external wall of a neck zone of a bottle portion. In addition, vertical convexities to block an opening turn of the cap portion provided on an inner periphery of the ring portion, and vertical convexities to block the opening turn provided on an external wall of a neck zone of the bottle portion, do not prevent attachment of the cap type sealing tool, but do prevent accompanied rotation of the ring portion during the opening of the cap portion to thereby allow breaking of the bridge part. At least one higher vertical convexity is provided as one of the vertical convexities provided on the inner periphery of the ring portion. Consequently, it is possible to prevent the ring portion from an erratic opening. Furthermore, the bridge part is not broken during temporary mounting of the cap type sealing tool and a subsequent opening thereof.

An electronic transaction terminal, in which a memory for information for storing therein an identification number inputted from a ten-key and a power unit for memory for supplying power to this memory for information are connected to each other with a film for printed pattern wiring (FPC). The FPC is placed throughout the internal surface of a security case. If someone tries to make a hole on the security case, any point of the wiring pattern of the FPC is cut off. For this reason, power supply to the memory for information is shut down and data on the memory for information is deleted.

A solar cell module is disclosed that includes a solar cell power generating unit and a connecting member. The connecting member supplies the output of a solar cell to an external electronic component. The connecting member includes a covering member and an output connecting portion. The covering member covers at least the surface of a terminal portion among the surfaces of the terminal portion and a protective member. The output connecting portion has one end disposed in the covering member and the other end disposed outside the covering member. The one end of the output connecting portion is connected to the terminal portion of the solar cell power generating unit. The other end of the output connecting portion has a terminal for connection to an electronic component.

A muffler system can include an exhaust pipe configured to be connected to an exhaust port of an engine, and a muffler containing a catalyst. The muffler is configured to be connected to a downstream side of the exhaust pipe, and can include a first protector stay covering an upper surface of a high-temperature portion of the muffler. The first protector stay creates a front opening and a rear opening between an upper surface of the muffler and front and rear portions of the protector stay. A muffler protector is attached to the protector stay, the muffler protector being configured to cover an upper surface of the muffler.
