Title: Direct drive electro-mechanical press for encapsulating semiconductor devices
Inventor: LIAN TIANG SIONG
IPC: B29C45/66
Filed: 1992-12-04
Abstract: A direct drive electro-mechanical press for encapsulating semiconductor devices comprises a clamping axis 122 for closing the mould, and a transfer axis 124 for injecting molten resin. The clamping axis comprises a planetary roller screw 132 coupled to a tie bar platen assembly on which a top mold 144 is mounted. A two-speed gearbox 128 provides a high speed mode and a high torque mode along the clamping axis. The transfer axis is slidably located above the clamping axis; the transfer axis comprises another planetary roller screw 150 coupled to a bottom platen on which a bottom mold 158 is mounted. The transfer axis transfers the moulding resin from the pot to the cavities formed when molds are clamped together. The planetary roller screw drive arrangement (fig. 5) allows the application of closure forces proportional to the drive delivered by the servo motors. A closed-loop control is provided to the clamping and transfer drives. The closed-loop control provides direct feedback on the clamping tonnage on the tie bars and transfer pressure in the mold blocks. The mold is first closed under light pressure (soft close) and the proximity of the mold blocks checked. If closure has been prevented by a foreign body the run is terminated. Otherwise the servo motors apply the predetermined damping tonnage. <IMAGE>

Patent GB-2301054-A (GB)
Title: Torque-angle wrench
Inventor: BECKER THOMAS P
IPC: B25B23/142
Filed: 1995-11-29
Abstract: A torque-angle wrench (100) is provided with a handle (104) for applying torque, such as to a fastener or bolt, through a tightening angle, at a rotational angular velocity. A piezoelectric gyroscopic sensor device (102) including circuitry for vibrating an oscillating body is coupled to the wrench. As the wrench is rotated through the tightening angle, its rotational angular velocity causes the vibrating body to alter its direction of vibration. The new vibrating pattern is sensed and converted, by appropriate sensing circuitry, into an electrical signal proportional in intensity to the rotational angular velocity of the wrench. The electrical signal can be electronically processed by appropriate conversion and display circuitry to provide a visual indication of the tightening angle. Such conversion and display circuitry can be integral with the wrench or as part of an adaptably coupled meter non-integrally connected to the sensor device.
Patent GB-2306219-A (GB)
Title: 3-D seismic survey using multiple sources simultaneously
Inventor: ANSTEY NIGEL ALLISTER
IPC: G01V1/153
Filed: 1996-08-20
Abstract: In three-dimensional seismic surveys using the Vibroseis system, multiple sources are used simultaneously, into the same set of geophones. Each source radiates a distinctive source signal, so that reflections generated by each one may be separated from those generated by the others. These signals should have little or no correlation with each other, and each should be substantially immune from harmonic distortion present in any of the others. The invention employs long but identical swept-frequency signals, for which the time to sweep through one octave exceeds twice the maximum seismic travel time of interest. For one swept-frequency signal (11) a frequency-time space (16) is defined between the signal itself and a nominated harmonic (14) (for example, the second), and the other swept-frequency signals (18) are accommodated within partitions of this frequency-time space. The invention is particularly appropriate to inexpensive swinging-weight vibrators.
