Title: Lathe turning tool and cooling method therefor
Inventor: TANABE IKUO
IPC: B23Q11/10
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To dispence with cutting oil by supplying a coolant to such a degree as to be evaporated by heat of a tool during machining of a part in the vicinity of the edge of a lathe turning tool, and utilizing heat of vaporization at the time of evaporation to cool the edge part. SOLUTION: Water in a water supply tank 5 is continuously supplied into a water reservoir 4 through a water supply pipe 6 with evaporation of water in the water reservoir 4 by a water level difference between the water reservoir 4 and the water supply tank 5 and a capillary phenomenon. The water reservoir 4 is filled with material excellent in water absorptivity such as shammy, whereby water in the water reservoir 4 is kept from being scattered to the outside by a little vibration at the time of cutting.  Thus, water in the water reservoir 4 is evaporated by heat of a throw-away tip 3 which becomes high temperature at the time of lathe turning at the lathe turning edge 3a of a lathe turning tool 3, and the heat of the throw-away tip 3 is rubbed by heat of vaporization so that the temperature in the water reservoir 4 of the throw-away tip 3 is kept below 100 deg.C to sufficiently lower the temperature of the edge 3a.

Title: Alkaline battery
Inventor: WATANABE SHUNJI
IPC: H01M2/04
Filed: 1994-05-09
Abstract: PURPOSE:To enhance performance and reduce production cost by using a copper- tin alloy in a negative pole can. CONSTITUTION:The outside 9 and inside 10 of a negative pole can of a silver battery are formed with an alloy comprising copper and tin in place of a nickel- stainless steel-copper three layer clad material to prevent the bulging of battery container caused by generation of hydrogen gas and deterioration in shelf life. A negative pole can core material formed of iron or brass and a copper-tin alloy layer is formed on the surface of the negative pole can to reduce production cost. After forming of the can, since the copper-tin alloy layer is formed by plating or vapor deposition, power of metal such as stainless steel and iron is not exposed on the surface of the inside 10. Since the copper-tin alloy layer is difficult to form on the inside 12 of turning up part of the negative pole can, when press forming is conducted after forming of the alloy layer, the core material is exposed at the negative pole can end 11. If the exposed metal is stainless steel or brass, corrosion is not produced, but if it is iron, care must be taken in environment for use, such as the inside of an appliance. By use of the copper-tin alloy, cost can be reduced.

Abstract: PURPOSE: To obtain a stable clamping force during the rotation of a drum by a method wherein a pressing force of the clamp member for clamping the rear end of the sheet is increased by means of a weight on which a centrifugal force is applied in the sheet clamping device to fixedly support the sheet around its drum.  
     CONSTITUTION: In a illustrated state that the front end of a the sheet S is held by a sheet end clamp pawl 4 on the drum 2 rotatable in the direction shown by an arrow, when a control lever 31 is swung downward, its end portion 31A is brought into abutment with a support shaft 22A so that a clamp roller 22 is prevented from rotating together with the drum 2. As the drum 2 is further rotated, the clamp roller 22 is pushed up from a recessed portion 21 to the surface of the drum against an urging force of a spring 26. Thus, the sheet S is adhered on the surfase of the drum under the pressing action of the clamp roller. Then, when the recessed portion 21 comes again just below the clamp roller 22, the control lever 31 is retreated and the clamp roller 22 is dropped down into the recessed portion 21 so that rear end of the sheet S is fixedly clamped. This clamping force is increased by means of a weight 23 on which a centrifugal force is applied.
