Filed: 1994-03-25
Abstract: PURPOSE:To ensure that the surface of a material to be cleaned such as silicon wafer is washed without inflicting a scratch by transmitting an oscillation from an oscillation transmission means to the tip of a tip cleaning member through a supporting shaft, and oscillating the tip cleaning member with a concurrent action to rotate it. CONSTITUTION:When a material to be cleaned 17 is deposited on a transport roller 16..., the material 17 is transported by the frictional force of the transport roller 16. Further, when the material 17 is transported to a position below a spray ejection pipe 45, a cleaning liquid is ejected toward the material 17. Next, when the material is transported to a position below a cleaning brush 23, the tip of a hairy member 23b of the cleaning brush 23 rotates to come into contact with the surface of the material 17, so that particles are removed from the surface of the material 17. In this case, an adequate cleaning power can be obtained, even if the contact resistance between the tip of the hairy member 23b and the surface of the material 17 is small, as the activation of an oscillation generator provided on the other end of a brush shaft 24 oscillates the tip of the hairy member of the cleaning brush 23.

Abstract: PROBLEM TO BE SOLVED: To provide a battery in which hydrogen gas is not generated, even if the air penetrates into its nonaqueous electrolyte by arranging an insulating liquid that does not have compatibility with the nonaqueous electrolyte and water on the upper part of the nonaqueous electrolyte. SOLUTION: A rupture disc 6 is, for instance, a stainless steel plate having a thickness of 0.2 mm and is an inside pressure releasing mechanism to be ruptured by a pressure above a specified pressure, when the inside pressure is abnormally increased by gas generation and temperature rise due to overcharging, large current discharge or the like.

Title: Manufacture of flat wire and side rail for oil ring
Inventor: MASUGATA YOSHIKI
IPC: F16J9/06
Filed: 1993-03-17
Abstract: PURPOSE:To provide a side rail for oil ring which does not generate a crack in an edge surface by forming the wire rod into a roughly rectangular shape by hot rolling for the formation of small sectional area, and finally forming the flat wire of prescribed dimensions. CONSTITUTION:A wire rod 1 whose sectional area with phi2mm-phi8mm straight line is substantially circular is heated by a high-frequency heating coil 2, and subjected to hot rolling into a rectangular cross section with a hot rolling roll 3 with a hole die. This is repeated twice continuously. After intermediate annealing process is carried out to restore the workability of a material, cold rolling is carried out once to obtain a flat wire whose thickness is 1mm or less. There are little wrinkle patterns in the flat wire and the sectional area is reduced from one flat wire to another flat wire, so load applied to the edge surface when rapidly rolling from a round wire to the flat wire is reduced, thus it is possible to prevent generation of wrinkle patterns which leads cracks in an edge surface. If all the processes are consolidated into the rolling, it is possible to prevent seizure from occurring which was a problem during conventional wire drawing, thus speeding up wire passing easily.
