Title: Manufacture of plastic molding from fluid reaction mixture and device therefor
Inventor: WIRTH JUERGEN
IPC: B29B7/76
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of cleaning time and a reaction mixture or entirely eliminate the loss by filling a mixing chamber and a discharge pipe with the reaction mixture having a reaction start time corresponding to waiting time between shots at the time of starting a new production cycle and cleaning the mixing chamber and the discharge pipe only at the time of each production cycle. SOLUTION: This device comprises a mold 9 to be filled with a reaction mixture in the downstream of a discharge pipe 8 of a mixing head 7 passing through storage tanks 1, 2 for a reaction component of isocyanate and polyol, supply lines 3, 4 and batching pumps 5, 6, the mold 9 being arranged on a circulating belt 11 of a filling station 10. The first mixing head 7 fills a cavity with a first reaction mixture and cures it and a second mixing head introduces a second reaction mixture into the cavity. A waiting time from the end of a first shot to the start of a following shot is shorter than a shortest time required for the start of a chemical reaction between the two mixtures and a molding is unloaded from the mold 9 by curing the second reaction mixture.  Thus the loss of time and a raw material is generated only during interrupting an operation and a cleaning process is substantially dispensed with.

Title: Fluid bearing device
Inventor: SAITO HIROAKI
IPC: F16C33/10
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that when a screw seal groove is formed, the groove is machined by a lathe at a process different from machining of a dynamic pressure generating groove on the radial side, there is a problem of productivity and machining precision and since the shape of a groove capable of being machined is limited, control of a seal force is difficult to make. SOLUTION: A screw seal groove 11 forms a groove continuing to a dynamic pressure generating groove 4c on the radial side and having the same angle and the same number of grooves as those of a dynamic pressure generating groove 4c on the radial side. Since this constitution enables the screw seal groove 11 to be continuously and simultaneously machined at the same process as that for the dynamic pressure generating groove 4c on the radial side by a rolling tool for groove machining, productivity and machining precision are improved and control of a seal force is facilitated.

Title: Control device for lock-up clutch
Inventor: OTA YUKI
IPC: F16H61/14
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a device by making the engaging pressure of a lock-up clutch appropriate. SOLUTION: In lock-up areas A, (steps 405, 415), a CPU gradually increases engaging pressure so as to equalize engine speed Ne and the input shaft rotating speed Ni of an automatic transmission (step 425) and holds the engaging pressure at the point of time when both are equal (step 430). The engaging pressure therefore has the value not maintaining the direct-coupled state of the lock-up clutch 26 against torque larger than torque applied to the lock-up clutch 26 during the generation of specified torque β smaller by the specified value than the maximum torque of an engine 10. Consequently, transient excessive torque is absorbed by the slip of the lock-up clutch, and a secondary characteristic spring of a damper mechanism can be omitted to reduce the cost of the device.
