Abstract: A solar cell lead wire includes a conductive material, and a solder plated layer on a periphery of the conductive material. The solder plated layer is formed flat by rolling. A method of manufacturing a solar cell lead wire includes feeding an elongate conductive material from a feed reel, the elongate conductive material including a rectangular conductor or a round conductor, soaking the conductive material in a molten solder in a molten solder plating bath, cooling the conductive material to have a plated wire with a solder plated layer formed on the conductive material, and winding the plated wire on a winding reel. The plated wire is formed flat by rolling after the solder plated layer of the plated wire is solidified by the cooling.

Abstract: Provided is a magnetic recording medium substrate appropriate for a discrete medium and capable of fabricating a magnetic recording medium to/from which data can be written or read stably. Coaxial grooves (2) are formed on the surface of a resin substrate (1). The groove (2) has a width (T2) greater than a width (T1) of a track (3). Accordingly, when a magnetic layer is layered on the resin substrate (1), magnetic layers formed on the adjacent tracks (3) are not brought into contact and it is possible to prevent the problem that the magnetic layer is embedded in the groove (2). Thus, it is possible to physically separate the track (3) by the groove (2) and fabricate a magnetic recording medium to/from which data can written and read stably.

Abstract: A beverage container handle is disclosed, fabricated from sheet material, such as rubber with rubber or fabric with rubber includes any biodegradable material or any other recyclable material. The handle comprises a cylindrical portion for receiving a beverage container and a “C” shaped handle portion. Both of these portions are fabricated from the same single continuous sheet. A Method of manufacturing the container handle includes handle members that are continuous with the cylindrical portion that wraps around the outer walls of a container held therein. Thus the handle is uniquely rigid, providing the user with a sense of firmness. A person using the handle need not have direct contact with the beverage container held therein, thus increasing his or her comfort level. Disclosed herein is a method of manufacturing and compacting the handle for easy storage and access of-the invention.
