Abstract: A cartridge includes upper and lower half segments butting against each other and containing a disk, a shutter provided on one side of the cartridge half segments for exposing or alternatively enclosing the disk, and a torsion spring attached to the shutter for biasing the shutter in a closing direction. An insertion opening is formed in a side portion of the cartridge for permitting insertion of the torsion spring therethrough from outside, and a protective wall is provided upright between the insertion opening and the disk to define a space by the wall and the upper half segment. The space is so sized as to permit the torsion spring to pass therethrough while leaving a small clearance, with legs thereof directed laterally.

Abstract: An apparatus for supporting an electric-component mounter including a substrate supporting device which supports a circuit substrate, an electric-component supplying device which supplies a plurality of electric components to be mounted on the circuit substrate, a mounting device which receives the electric components from the electric-component supplying device and mounts the electric components on the circuit substrate supported by the substrate supporting device, and a base member which supports the substrate supporting device, the electric-component supplying device, and the mounting device, the apparatus including at least one elastic member which is provided between the base member and a surface of a floor which supports the base member, and at least one damper which damps vibration of the base member and the floor surface relative to each other, the vibration resulting from elastic deformation of the elastic member.

Abstract: Ag and Cu are added to a base material of a Sn/Pb/Bi composition. Since Bi is contained in greater quantities in Sn/Pb, the alloy has a low melting point (120 to 150.degree. C.) and is surely melted at reflow temperatures from 170 to 200.degree. C. Preferably, the addition amount of Ag is from 0.1 to 5 wt % and the addition amount of Cu is from 0.05 to 1.0 wt %. A low-melting alloy having all the required performances and excellent with view points of cost and safety and a cream solder using a powder of the alloy can be obtained.

Abstract: A band seal is formed between a body and a cap of a capsule by fitting the cap on the body, and applying a gelatin-base sealant at least one time in the form of a band spanning the cap and the body. Band sealing is carried out by at least one of the following steps (A) to (E): the step (A) of applying the sealant at a temperature of 30-40.degree. C. at least when the sealant is first applied, the step (B) of applying the sealant at a viscosity of 50-200 centipoises at 50.degree. C. at least when the sealant is first applied, the step (C) of after the sealant is applied, blowing cold air at a temperature of up to 10.degree. C. to the band seal to cool the band seal below 10.degree. C., the step (D) of reducing the joint distance between the body and the cap shorter than the standard capsule length, and the step (E) of applying the sealant to only an edge adjacent portion of the cap surface when the sealant is first applied. The invention prevents bubbles from generating in the band seal.
