Title: Recursive noise-reducer
Inventor: KITAURA MASAHIRO
IPC: H03H17/04
Filed: 1989-03-13
Granted: 1991-10-29
Abstract: ABSTRACT OF THE DISCLOSURE      A recursive noise-reducer for a high-definition TV system.  The noise-reducer includes an interpolation device for performing two-frame interframe interpolation on the input digital signal.  A delay device delays the input digital signal by one frame period and two frame period.          An output signal from the delay device is separated into a one-frame-preceding signal component and a two-frame-preceding signal component.  A first subtracter derives a difference between the input digital signal and the one-frame-preceding signal component.  A filter filters an output signal from the first subtracter and passes a signal component having a recursion with a period corresponding to one frame.  A second subtracter derives a difference between the input digital signal and the two-frame-preceding signal component.  An adder adds the input digital signal, an output signal from the filter, and an output signal from the second subtracter.  The interpolation device operates to alternately select an output signal from the adder and the one-frame-preceding signal component and thereby to generate the interpolated signal from which noise components are effectively reduced.

Title: Distributed push-pull amplifier
Inventor: GRUCHALLA MICHAEL E
IPC: H03F3/68
Filed: 1989-03-13
Granted: 1991-04-30
Abstract: DISTRIBUTED PUSH-PULL AMPLIFIER                ABSTRACT OF THE INVENTION The present invention provides a modified distributed amplifier which is capable of providing push-pull operation without the loading losses of conventional push-pull combining. The modified distributed amplifier comprises a distributed amplifier configuration and with signal inverting means, such as a wide bandwidth transmission line transformer, interconnected into both the input and output lines. The signal inverting means are most effectively placed at the electrical centers of the lines, but may be placed at any positions in the individual lines to produce optimum performance to specific applications. The separate segments of the distributed amplifier separated by the signal inverting means operate in opposed phase but the signals output to the load add in phase thus providing push-pull operation. Since only one reverse terminating resistor is required, the power normally lost due to the loading by the companion amplifier of a conventional push-pull combined distributed amplifier system is instead delivered to the output load. The use of this type of amplifier preserves the advantages of the distributed amplifier configuration while providing the superior performance of the push-pull configuration but without the losses normally incurred with conventional push-pull combining.

Abstract: Large size packings of napkins, paper rolls, quilts etc. normally appear as tight plastic sheet packings of a block-like shape. As a carrier handle is used a strong strip of sheet material which extends across a side panel of the packing, what is disadvantageous for the visual impression of the packing. A carrier handle cannot be formed direct in the packing sheet, as the packing will then no longer be dust proof. According to the invention the handle is made in that manner anyway, but inside the handle area a barrier layer (12) is provided in order to make the packing dust proof. Preferably a carrier handle strip portion (6) is prepared between easily breakable weakening lines (4), whereby the handle panel of the packing may show a high quality stamp regardless of the handle.
