20080199551 | INJECTION MOLDING MACHINE - An injection molding machine capable of accurately detecting a rotational force exerted on a screw by resin backflow to easily evaluate states of resin backflow and closure of a check valve. In a state where the screw is stopped axially and rotationally after metering is finished, a load exerted on the screw in the rotational direction is detected. This load is a rotational force exerted on the screw from resin remaining between flights of the screw (resistance torque component). During injection, a load T exerted on the screw in the direction of rotation is detected, and the resistance torque component is subtracted from the detected load T to obtain a backflow torque component generated by resin flowing back through the check valve. By simultaneously displaying waveforms of backflow torque components in a plurality of molding cycles to be overlapped, stability of closure of the check valve is readily evaluated. | 08-21-2008 |

The electrically conductive member has a first end exposed at an inside of the main body, and a second end grounded. | 06-24-2010 |
20100166904 | Alternate Polymer Extrusion system with accumulator - An extrusion system and method uses an accumulator to control and use excess plastic melt. The accumulator is situated between an extruder and a gear pump. The accumulator includes an accumulator housing to store excess plastic melt from the extruder and an accumulator spring connected to an accumulator piston to subsequently send the excess plastic melt to the gear pump. In another embodiment, the accumulator includes an accumulator housing to store excess plastic melt from the extruder and a hydraulics system to send the excess plastic melt to the gear pump. The accumulator can be a first in first out (FIFO) device having a melt passage through the accumulator piston. The system and method are used particularly advantageously in Alternate Polymer extrusion installation in which gear pumps regularly increase and decrease their speed but in which the melt-supplying extruder cannot accommodate such rapid speed changes. | 07-01-2010 |

20160089839 | THREE-DIMENSIONAL PRINTING APPARATUS - A 3-D printing apparatus includes a frame, a tank, an automatic-filling module and a control unit. The tank is disposed in the frame and contains a liquid-forming material. The automatic-filling module includes a sensing unit, a reservoir, a filling pipe and a pressuring unit. The sensing unit detects a liquid level of the tank. The reservoir stores the liquid-forming material. The filling pipe connects to the reservoir and includes an outlet. A maximum liquid level of the liquid-forming material in the reservoir is lower than or equal to a level of the outlet. A gap exists between the outlet and a top edge of the tank. The pressuring unit provides a positive pressure to the reservoir so that the liquid-forming material in the reservoir flows to the tank. The control unit determines whether the pressuring unit provides the positive pressure to the reservoir according to the liquid level. | 03-31-2016 |

20080274224 | Precompression Pin Shut Off with Suckback - An injection nozzle is provided having a nozzle body, defining an inlet channel, an outlet channel and a connecting channel therebetween for communicating a working fluid into and out of the nozzle body. A shut-off pin is slidably mounted within the nozzle body and having a spigot mounted thereto. The shut-off pin is movable between a closed position, where the working fluid is substantially blocked from moving from the inlet channel to the outlet channel, and an open position where the spigot is withdrawn, unblocking the working fluid from moving from the inlet channel to the outlet channel. An actuator is operably connected to the shut-off pin to move the shut-off pin from the open position to the closed position. Moving the shut-off pin from the open position to the closed position generates a region of low pressure in the working fluid in the portion of working fluid trailing the spigot. | 11-06-2008 |
20090311358 | INTEGRATED APPARATUS HAVING KNEADING PART AND INJECTING PART - In an apparatus which has a kneading part for performing kneading of a material and an injecting part for performing injection of the material for injection molding with the kneaded material and in which the kneading part and the injecting part are connected together, a weighing screw channel portion for weighing the material and a retention screw channel portion that is formed adjacently to the weighing screw channel portion with its channel shape made different and forms a material retention space for retaining the material fed continuously quantitatively from the kneading part are formed on the injection screw shaft. Thereby, the material fed continuously quantitatively from the kneading part can be securely retained in the injecting part where intermittent operation is a performed. | 12-17-2009 |
20130295211 | MACHINE FOR PRODUCTION OF SOLID DOSAGE FORMS - In one aspect, the present invention features a machine for the production of a solid dosage form wherein the machine is adapted to form a dosage form between a first forming tool and a second forming tool within a forming cavity and wherein the first RF electrode and the second RF electrode are arranged within the machine such that when RF energy is applied between the first RF electrode and the second RF electrode, the RF energy passes through the portion of the forming cavity adapted to form the dosage form. | 11-07-2013 |
