Abstract: There is provided a groove machining tool supported in a holder and caused to move together with the holder in relative fashion along a scheduled scribe line over an integrated thin-film solar cell substrate to form a groove. The groove machining tool includes a tool body supported in the holder, and a blade tip part formed in a distal part of the tool body. The blade tip part includes a blade extending along a direction intersecting a direction of movement of the tool, at a first end along the direction of movement of the tool. The blade is tilted backward from the direction of movement of the tool in relation to a direction orthogonal to the direction of movement of the groove tool, as viewed from a bottom face of the blade tip part.

Abstract: A glass substrate transport box which is easy to handle and transported and adapted to protect glass substrates is provided at drastically reduced production cost. At least the body of the box is a molded piece of resin foam with a foaming ratio of 3-30, e.g. polyolefin foam, which has grooves for supporting glass substrates on at least a pair of its opposed inside walls. Preferably the inside wall of the body has a relatively dense skin layer. The resin foam may contain an electrically conductive polymer or an antistatic agent.

Abstract: An information signal record medium of an electrostatic capacitance type in which a signal information is recorded as geometric variations is described. The medium is made of a conductive resin composition which comprises a vinyl chloride resin and 5 to 30 parts by weight of conductive particles based on 100 parts by weight of the vinyl chloride resin. The vinyl chloride resin is obtained by polymerizing at least one monomer for the vinyl chloride resin in which from 0.2 to 1 parts by weight of a lubricant per 100 parts by weight of the vinyl chloride resin is dissolved.

Abstract: A display cell comprises first and second substrates, an injection hole, an element for narrowing the distance between the injection hole and its confronting plate as compared to major parts of a compartment defined by the first and the second substrates. Since the separation in parts of the display cell adjacent the injection hole is small, a sealing member for sealing the injection hole has resistance to a mechanical shock applied to the display cell because of tight installation of the sealing member.

Abstract: High density information signal recording media of an electrostatic capacitance type, in which an information signal is recorded as geometric variations. The medium consists of a conductive resin composition which comprises a vinyl chloride resin, carbon black particles and a silicone oil lubricant. The carbon black particles are treated with a silicone oil to have the oil coated thereon.
