Abstract: Method and apparatus for sealing cover tape. A sealing mechanism is connected to an actuator that moves the mechanism toward an adhesively backed cover tape and a carrier tape. The sealing mechanism applies heat and/or pressure to the cover tape to activate and bond the cover tape to the carrier tape. A biasing member biases the mechanism away from the cover and carrier tapes. The actuator is actuable to overcome the biasing force of the biasing member and to initiate contact between the sealing mechanism and the cover tape. When the actuator is disengaged, the biasing member moves the sealing mechanism away from the cover tape.

Abstract: It is necessary for the stroke of squeeze pin to be controlled so as to reach a defined target stroke position or zone during each shot operation of a die-casting machine. To achieve such control of squeeze pin, controlled variables T, Q or P are set in a trial molding process. The setting operation of the controlled variable is executed in a short time automatically. In case of adopting flow rate Q supplied to the squeeze cylinder as a controlled variable, the initial setting value Q1 is defined as 50% with conversion of opening degree of a flow control valve. Then, if the stroke of the pin is out of target, flow rate Q2 is set, which is defined as 75% corresponding to a intermediate value between the maximum degree of opening 100% and 50% at Q1. In a similar way, flow rates Q3, Q4, Q5 are set, namely, each Q3, Q4, Q5 is defined as the intermediate value between controlled variables set in consecutive two shots ahead. In case of Q5 the detected stroke of the squeeze pin is within the target stroke zone.

Abstract: The invention concerns a tube (1) internally divided into two longitudinal channels (16) by a median spacer (9). In an end zone (4) penetrating a fluid box (19), the tube is deformed so as to be widened in its transverse section and shortened on either side of the spacer in the direction thereof. The space requirement of the fluid box in the longitudinal direction of the transverse sections of the tubes, and consequently the space requirement of the whole heat exchanger, can thereby be reduced relatively to the maximum space requirement of the array formed by the tubes and the separators (5) stacked therewith. The invention is applicable to cooling radiators of engines powering motor vehicles.

Abstract: The present invention generally relates to a method for recovering productivity of an existing well. First, an assembly is inserted into a wellbore, the assembly includes a tubular member for transporting drilling fluid downhole and an under-reamer disposed at the end of the tubular member. Upon insertion of the assembly, an annulus is created between the assembly and the wellbore. Next, the assembly is positioned near a zone of interest and drilling fluid is pumped down the tubular member. The drilling fluid is used to create an underbalanced condition where a hydrostatic pressure in the annulus is below a zone of interest pressure. The under-reamer is activated to enlarge the wellbore diameter and remove a layer of skin for a predetermined length. During the under-reaming operation, the hydrostatic pressure is maintained below the zone of interest pressure, thereby allowing wellbore fluid to migrate up the annulus and out of the wellbore.
