Title: Button type alkaline battery
Inventor: WATANABE OSAMU
IPC: H01M50/195
Filed: 1982-05-07
Abstract: PURPOSE:To improve the leakageproofness of a button type alkaline battery by using an annular gasket whose degree of crystallization is improved by nylon 66 containing a specific amount of carbon black. CONSTITUTION:Nylon 66 containing catbon black by 0.05 to 1.0wt% is molded into an annular gasket with a preset form by an injection molding machine or the like. Since the degree of crystallization of nylon 66 in thus obtained gasket is low, it is raised to 30 to 50% by heating and processing nylon 66 in the environment of vacuum or an inert gas such as N2, Ar, and water vapor. Even if the degree of crystallization is raised as shown above, however, the deformation of the gasket is prevented by the presence of carbon black. As a result, the fitting of the gasket in a negative electrode terminal block is performed properly and a battery with good leakageproofness can stably be obtained.

An actual value SO in case of rolling by a previous process device 3 of the pipe, and an actual value LO after rolling are stored in the device 2. Accordingly, sectional area information of the device 3 is shown by unit weight of W/LO. When the pipe reaches in front of a device 4, a roll screw-down position S1 where unit weight of the tube at the delivery side of 1 pass becomes a target value is calculated by the stored information, target unit weight of the pipe at the delivery side of 1 pass, and a unit weight actual value of the pipe rolled by the plug used by its pipe. As for 2 passes, a roll screw-down position S2 is calculated by an actual value W/L1 at the delivery side of 1 pass, a target value W/L2 at the delivery side of 2 passes, and a unit weight actual value of the pipe rolled by the plug used by its pipe.

Title: Holder for tools
Inventor: KURAUSU TERUNAA
IPC: B23B31/11
Filed: 1984-04-19
Abstract: A receiver body (1) carries a holder shaft as needed and has on one end face an abutment face (4), extending at right angles to the axis of rotation, and a coaxial, conical receiving bore (5). A connection part (14), which is preferably embodied as a tool carrier, likewise has on one end face an abutment face (15, 15'), extending at right angles to the axis of rotation, as well as a coaxial, conical centering stub (16) fitting into the conical receiving bore. In order to assure a high degree of concentric accuracy, even in the event of strong forces exerted laterally upon the connection part, the inner cone (6) surface of the receiving bore (15) has a cone angle that is larger by a predetermined, small difference angle (27) than the outer cone surface (17) of the centering stub (16). This difference angle is such that upon the insertion of the centering stub into the receiving bore, the outer cone comes into engagement with the inner cone surface first in the vicinity of its smallest diameter. At least one of the two cones is elastically deformable so that the two cones engage one another over essentially their entire length and face and provide for matching engagement of the abutment faces (4, 15).
