Title: Process for preparation of cadmium stannate films
Inventor: HAAKE G
Filed: 1979-01-17
Granted: 1982-07-28
Abstract: Cadmium stannate transparent conductive films are formed on glass surfaces by sputtering at high frequency or by continuous flow.  Also, the cadmium stannate is sputtered from a target made of an alloy of Cd and Sn in a mole ratio of 1.7-2.5 : 1 in an oxygen plasma.  The sputtering is first effected for long enough to bring the target to equilibrium prior to introducing the substrate to the spray chamber.  Large targets can be prepared without the expensive pressing and sintering techniques required in making cadmium stannate hot pressed targets, in much less time.

Title: Signal conditioning method and apparatus for fm code signal
Inventor: TABATA GEORGE K
IPC: G11B20/10
Filed: 1983-07-15
Granted: 1987-04-25
Abstract: The digital FM code signal is encoded as an FM signal of limited bandwidth by limiting the bandwidth of a generated FM code signal and altering the phase equalisation of the FM code signla. The bandwidth- limited and phase-equalisation-altered FM code signal is then recorded as an AM signal on a recording track, and the recorded FM code signal is recorded. The phase equalisation alteration is performed with that the phase distortion of the phase-equalisation- altered signal occurring during the recording an recoveing steps result is in a signal with no phase distortion relative to the generated FM code signal.

Abstract: The device is designed to clean needles attached to  the  tip of an injection tube which applies epoxy resin  adhesive  throught eh needles on the lead frame pad to bond chips  to  the  pad.  The detergent solution (12) is pumped from a tank (1') to flow through a pipe (13) and nozzles (3) attached to the cover (2)  of  another trank (1) and is fed via a pipe (4) held by an adapter (5) into an injection tube (6) to the tip (7) to  be  discharged  through  the needles to the tank (1), which communicates via a filter with  the tank (1'). The pressured discharge of the detergent dissoves epoxy resin remaining on the inner wall of the tip  and  needles  to  be charged for cleaning.
