Title: Injection molding device
Inventor: KAMIYAMA KUNIHIRO
IPC: B29C45/77
Filed: 1994-09-29
Abstract: PURPOSE: To obtain an injection molding device that never causes a difference in a final in-mold pressure even with the change of the viscosity, elasticity, or the like of a molding material, contributes to a product quality enhancement, can stabilize a cycle time, and can raise a productivity. CONSTITUTION: A hydraulic cylinder 12 is so controlled as to make the speed of an injection screw 10 constant. The hydraulic cylinder 12 is so controlled as to lower the speed of the injection screw 10 at a constant acceleration if an internal nozzle pressure increases to a predetermined threshold or more in a last stage of injection molding. At the same time, a pressure of a molding material in a mold 4 is predicted by calculating a pressure increase in the mold 4. When the predicted in-mold pressure reaches a predetermined pressure, an acceleration constant control is changed over to a dwell control.

Title: Speed change operation device for combine or the like
Inventor: IIIZUMI KIYOSHI
IPC: F16D11/04
Filed: 1988-09-19
Abstract: PURPOSE:To simplify construction of the aimed device and prevent operation error by providing a power take-off clutch for turning power take-off transmission from an input shaft to a power take off part to off while interlocking with transfer to neutral position of gear change key in a speed change shaft. CONSTITUTION:Transmission from an input shaft 1 to a power take-off part 6 is turned on or off through a power take-off clutch 7 on a speed change shaft 3 to transmit power always in a definite transmission ratio regardless of position of speed change transmission by a speed change key 5. Since the power take-off clutch 7 is operated to turn-off position by operating the speed change 5 key from speed change position to neutral position N, transmission from the power take-off part 6 to a working machine is not carried out when running transmission is in neutral position. Further, the construction of the aimed device is also simplified and the device is free from operation error, since the speed change key 5 operates the power take-off clutch 7 together with gear change.

IPC: H02G3/30
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a fastening jig for wire harnesses whereby even a person who is not strong can tighten the wire harness firmly. SOLUTION: In a fastening jig 1 for wire harnesses, whereto a wire-harness bundling band 4 having a plurality of fastening pieces 2 provided continuously on its surface, a fastener 12 for locking the band 4, and a clip 7 are attached integrally therewith, each fastening piece 2 provided on the surface of the band 4 traverses the band 4. Since each fastening piece 2 is provided on the band 4 for traversing it, the resistances generated by the fastening pieces 2 when pulling the band 4 are made small to enable even a person who is not strong to firmly bundle the wire harness by the band 4. Therefore, preventing the tightening position of the band 4 from shifting, and degradation of the attaching workability of the wire harness is eliminated.
