Title: Method for forging double row ball bearing outer ring stock
Inventor: YOSHIOKA MORIHISA
IPC: B21K1/04
Filed: 1989-08-28
Abstract: PURPOSE:To improve the yield of material and to reduce the turning manhour by lengthening a ringed stock through non-restraint forward and backward extension in the axial direction, then, upsetting the central part of the inner diameter surface inward to form an annular projection and obtaining a stock having a shape near the outer ring. CONSTITUTION:After the ringed stock 10 is loaded, an upper punch 23 is lowered. The tip part of a lower punch 21 and a forming shaft part 25 of the upper punch 23 invade the inside of this stock 10. The upper and lower tip parts of the stock 10 are lengthened by the tapered surfaces 26 of the punches 21, 23 in the axial direction and in the radial direction and the inner and outer diametral surfaces are formed successively from both ends. When the upper punch 23 is lowered further, the stock 10 is pressed by an ejector 22 and a step 24 in the axial direction and, consequently, the central part of the inner diametral surface of the stock 10 is swollen toward the inner part. When the upper punch 23 is lowered down to the lower limit position, the upsetting is completed and an annular projection 12 is formed in the central part of the inner diametral surface of the stock 10. After forming is completed, the upper punch 23 and the ejector 22 are elevated and a formed part is taken out by the ejector 22 on the upper part of the forming die 20.

IPC: G01N11/12
Filed: 1985-10-07
Abstract: PURPOSE:To measure viscosity with high precision over a wide rane by finding the viscosity from specific calculation expressions when a falling time (t) is smaller than a specific value tM, and when tm<5<tM respectively. CONSTITUTION:Various liquid sampled from a pipe 1 is returned to the pipe 1 through a switching valve 4, a sample intake 7, a circular pipe 6, an outflow 8, and a sample return port 9 when a sample is replaced or through the valve 4 and return port 9 when the viscosity is measured. Then, the viscosity of the liquid is calculated from the speed (v) at which a falling ball 10 falls while rolling along the internal wall surface of the circular pipe 6. Namely, the falling time (t) of the ball is found by a subtracting circuit 14 on the basis of the outputs of ball falling detectors 11a and 11b. A comparator 15 compares the output (t) of the circuit 14 with the specific values tm and tM. The output of the circuit 14 is sent to a viscosity coefficient calculating circuit 16 when t<tm, to a viscosity coefficient calculating circuit 17 when tm<t<tM, and to a viscosity coefficient calculating circuit 18 when tM<t, so that the viscosity mu is calculated from the specific calculation expressions c1 (rho, t), c (rho, t), and c2 (rho, t) respectively.

Abstract: PROBLEM TO BE SOLVED: To provide a method for improving a ground, capable of maintaining the hardness strength of soil within a predetermined range with a solidifying material such as a cement and capable of surely performing the insolubilization of pollutants contained in soil. SOLUTION: This method for improving a ground comprises mixing a polluted soil containing a pollutant such as lead or its compound with a pH-adjusting material together with a solidifying material such as a cement. Namely, a solidifying material such as a cement is mixed with a pH-adjusting material such as lime powder, and the obtained mixture is mixed as a soil-solidifying material with a polluted soil. Thus, the elusion of the lead and its compound can be prevented, and the hardness strength of the soil is limited within a constant range due to the solidifying material. The amount of the cement is limited to a necessity minimum, and the solidifying material necessary for improving the ground is supplied with a mixing material such as the pH-adjusting material. In a powder jet machine mixing method, a pH-adjusting material to be mixed is used in the form of powder.  In a slurry deep level mixing treatment method, a cement is preliminarily mixed with a pH-adjusting material by the use of an agitator, and the obtained mixed materials are slurried with water and then used.
