The machine includes a frame, a mold unit, a grain supply unit, a grain transfer unit, a mold pressure arm, a drive unit, an open cam, a control unit and a cover unit. A precise charge of cereal grain is metered at the grain supply unit and in synchronism with the mold open cycle, distributed evenly over the mold cavity. Then with the mold unit clamped closed, the charge is heated and, at the end of the baking cycle, a preform is produced with gases at high pressure entrained therewithin. Upon release from the mold, the preform expands to a grain cake of the desired size. The machine controls the thermal energy input, the cycle frequency, the size of the grain charge, and the ejection trajectory. Several interrupts are used to ensure conformance to the control parameters and to enhance operator safety.

An electrostatic plate capacitor is embedded in the mold, serving as the deformation detector. The capacitor includes two opposite metal film electrodes formed by silicon micromachining technique on opposite surfaces of the mold and connected by a metal lead. During imprinting, the mold is acted upon by an external force and deformation occurs, which induces change of distance between the metal film electrodes and thus variation of the capacitance of the capacitor. The amount of deformation of the mold can then be assessed by comparing the capacitance with a reference. Thus, real-time detection and monitoring of the deformation of the nano-imprint mold is realized. Also disclosed is a method for carrying out the real-time monitoring of the deformation of the mold.

  • Patent number: 6902384
    Abstract: An apparatus for melt spinning and cooling a group of filaments comprising a spinning device with an annular spinneret and a cooling device arranged below the spinning device. The cooling device comprises a holder that is connected to a coolant dispersing head. The coolant dispersing head is centered relative to the spinneret with contact between the spinning device and the holder in an operating position. The coolant dispersing head can be guided into a standby position at a distance from the spinneret. A guide tube encloses the coolant dispersing head in the manner of a jacket with a clearance and which is open at its end facing toward the spinning device. The guide tube and coolant dispersing head are displaceable relative to one another in axial direction to produce an air stream at the blowing end of the guide tube during transition from the standby position to the operating position.

  • Patent number: 6833092
    Abstract: In a method for controlling a motor-driven injection molding machine which includes a drive motor provided at a drive section, a load level of the drive section for each molding cycle is obtained in order to determine whether the load level has entered an overload region. When the load level has entered the overload region, cycle-time prolongation processing is performed in order to obtain a cycle prolongation time corresponding to the load level and to prolong the molding cycle by the cycle prolongation time.

  • Patent number: 6776598
    Abstract: A semiconductor chip molding apparatus includes an upper platen including an upper mold, a lower platen including a lower mold having a molding block configured to receive a lead frame, a controller, and an electrical detector for forming an electrical circuit between the controller and the lead frame when the lead frame is oriented improperly on the lower mold. A low-level test voltage is imparted to at least the lower mold. As a result, an electrical signal will flow from the detecting block when the lead frame rests on the detecting block. When such a signal is detected, therefore, the lead frame is determined as having been improperly set on the molding block. The signal generated is detected by a controller and used thereby to interrupt the operation of the molding apparatus.

  • Patent number: 6669877
    Abstract: This invention provides a method which makes it possible to reliably detect malfunctions during the ejecting step without rendering the injection molding machine more complicated. An ejector pin is incorporated in the movable die. This ejector pin is connected, via an ejector plate, a connecting rod, a connecting plate and a feed screw, with a servo motor. The force for ejecting the ejector pin pushing a molded product is measured from the driving torque of a servo motor. In this invention, the relationship between driving torque and elapsed time from the initiation of ejection of the molded product is stored as a reference pattern. The tolerance limit and monitoring interval of driving torque are preset relative to the reference pattern. When the value of driving torque falls outside the tolerance limit during the ejecting step, it is judged as a malfunction, and an alarm is generated to stop the machine in a safe state.

  • Patent number: 6652785
    Abstract: An extrusion system controller monitors the movement of an extrudate using a motion detector. Upon detection that the extrudate is no longer moving along its path of movement at the appropriate speed, the controller causes power interruption to the extrusion system by a controlled power switching device. A dimensional anomaly detected by a gauge can cause the controller to effect power interruption as well, when the anomaly lies outside a range of correctable dimensions or when the anomaly does not respond to corrective action by the controller. In the event that a cutter is used on the extrusion line, a detector that may be a photodetector senses that the extrudate is being severed regularly. In the absence of regular severance of the extrudate, the controller effects a power interruption. By use of these techniques, the extrusion line can run entirely unattended.
