Title: Thermal treatment apparatus and method
Inventor: SASAKI TAMOTSU
IPC: B01J4/00
Filed: 1984-09-26
Abstract: In a method of subjecting semi conductor wafers to a thermal treatment in a furnace tube (102) a horizontally extending carrier (141) having a portion (141a) adapted to a plurality of wafer jigs thereon is moved to a predetermined position (Fig. 10B) in the furnace and the wafer jigs are located at this position. The carrier is then withdrawn to another position close to the opening of the furnace tube (Fig. 10C) and the opening of the furnace tube is closed by inner and outer caps (143, 144). The wafers on the jigs are subjected to thermal treatment while the carrier (141) is advanced and withdrawn periodically to and from the said predetermined position to lift of wafer jigs to prevent fusion of the jigs to the tube. The apparatus includes means for automatic control of the movement of the semi conductor wafers in accordance with thermal treatment conditions. <IMAGE>

Title: Optical signal processing
Inventor: EPWORTH RICHARD EDWARD
IPC: G02F1/01
Filed: 1985-05-04
Abstract: The phase of modulation of an optical signal (Pin), in particular intensity modulation, is controlled to a predetermined value by applying the signal in a predetermined power split ratio to an unbalanced fibre Mach Zehnder interferometer (10) which is sure that the signals applied to its output coupler (13) are in-phase and quadrature (I, Q), the phase of the output signal Pout 1 being determined by the power split ratio. The predetermined power split ratio is achieved by causing an appropriate optical phase difference between the optical signals in the arms (3, 4) of fibre Mach Zehnder interferometer (1). If required the amplitude of the phase controlled Pout 1 signal can be controlled by a third fibre Mach Zehnder interferometer (17). <IMAGE>

Title: Compressed air powered suction unit
Inventor: COLEMAN JAMES DAVID
IPC: A47L5/18
Filed: 1985-08-06
Abstract: A unit uses compressed air to produce a suction force. This force can be applied in a portable manner either directly from the unit, or with the unit as part of a larger system, to remove materials and transport them to a preferred location. A Coanda surface 3 and divergent section 4 are used to enhance entrainment into a primary flow of compressed air from the peripheral nozzle 10. The flow of compressed air is controlled by a manually- operated valve 7. The overall flow results in suction at the unit inlet 2. The suction is applied to materials which are transported through the unit body and via the pipe 11 to a preferred location. The unit can easily be adapted for use as a portable blow gun which produces a high mass flow, low pressure jet. <IMAGE>

Title: Arithmetic assembly
Inventor: WOOD DAVID CHARLES
IPC: G06E1/04
Filed: 1987-02-19
Abstract: An arithmetic assembly comprises a number of summing devices (9, 10 Figs. 3, 5) arranged in series. Each summing device has two input ports (A, B) and two output ports (5, 6A) and is adapted to generate signals at its output ports representing respective bits of the sum of two single bit values represented by optical signals supplied to its input ports. The output ports (5, 6A) of the leading p devices (Fig. 5) are each connected to respective input ports (A, B) of the adjacent downstream device and the input ports of the leading device each receive, in use, respective optical signals representing in series the bits of two p bit values to be summed. A delay (11 Figs. 3, 5) is built into the path of the most significant bit between adjacent devices so that the least significant bit supplied to the input port (A) of each device is summed with the most significant bit of the previous sum generated by the corresponding leading device. With combination of signals at the B port of the second device (Fig. 5), two p-bit values may be added using two summing devices. In order to reduce the intensity of the signal relating to the most significant bit when two binary one values are summed, a Y-coupler (7) is positioned upstream of the output port (6A) to reduce the intensity by 50%. <IMAGE>
