Abstract: Stacks of paper sheets (3) are transported from a sheeter into a wrapper by the upper reach of an endless infeed conveyor. The front end faces of successive stacks catch up with and are decelerated by successive flights (8) on an endless second conveyor (7) which is driven at a speed less than the speed of the corresponding section of the infeed conveyor. This ensures that the dimensions of so-called tails, consisting of lowermost sheets of a stack which are shifted rearwardly with reference to the sheets above them, are reduced in size or that the tails are eliminated before the stacks enter the wrapping station. Misoriented stacks are reoriented ahead of the second conveyor by two endless lead-in conveyors having flexible belts trained over vertical pulleys and defining a channel the width of which decreases in the direction of advancement of the stacks. That portion of the path for the stacks where the stacks advance toward and thereupon move with the flights on the second conveyor is flanked by a pair of endless tapes, which are overlapped by the lateral portions of the stacks, and by two sidewalls. The sidewalls are movable toward and away from each other to thus alter the effective width of the path for the stacks. The tapes are movable toward and away from each other at a rate which is less than the rate of movement of the sidewalls.

Abstract: In a semiconductor device, charge carriers are locally depleted by a lateral surface superlattice grid structure (21, 22) formed on top of semiconductor material, leaving charge carriers in periodic potential wells with respect to the depleted areas. Said grid structure (21, 22) acts as the gate electrode of a field-effect transistor such as a HEMT and is formed selectively according to a desired pattern (20) (e.g. square, circular...) on portions of the top semiconductor surface. In order to have a device which exhibits negative differential conductivity at ambient temperature, the periodicity of the grid structure must be less than 800Å.

Abstract: Disclosed is a process for the preparation of a perfluorinated copolymer having a predetermined ratio of monomer units, which comprises copolymerizing 99.5 to 50 mole% of (I) tetrafluoroethylene with 0.5 to 50 mole% of (II) a monomer represented by the following general formula:
     CF 2  =CFOCH 2 C n F X m H (2n+1-ℓ-m)  (II)     
wherein X stands for -Ct or -Br, n is an integer of at least 0, t is an integer of from 0 to (2n + 1), m is 0 or 1, and the relation of t + m ≦ 2n + 1 is established,  
in the state where both the monomers are dissolved at a predetermined monomer ratio in an organic solvent, to thereby form a copolymer comprising units of the monomers at a ratio substantially equal to said predetermined monomer ratio, and fluorinating said copolymer with molecular fluorine.
     The heat resistance is highly improved in the copolymer obtained according to this process without degradation of other physical properties, and generation of hydrogen fluoride by heat is hardly caused. Since the molar ratio between the starting monomers can be substantially maintained in the formed copolymer, the composition of the copolymer can be easily controlled.

Abstract: An MSK signal detector uses a limiter to convert an input signal to a signal with only two levels. A transition interval decision and memorizing circuit decides whether intervals between transitions between these levels fall into windows centered at the half-period of the MSK space frequency and the half-period of the MSK mark frequency, or a window centered midway between these two. An MSK decision circuit tests the pattern of decision results to detect patterns corresponding to MSK input. Output from the MSK decision circuit is low-pass filtered and thresholded to produce an MSK detect signal indicating the presence of MSK input. A compact, low-power circuit structure is achievable. The circuit can be adapted for quick preamble detection by simple modifications to the MSK decision circuit and low-pass filter.

Abstract: A piezo-resistive pressure sensor element (20) is formed in the front face (26) of a silicon wafer (12). A thin diaphragm (16) is formed under the sensing element (20) by anisotropically etching a cavity (14) from the rear face (23) of the wafer (12). The rear face (23) (cavity-side) rupture pressure of the silicon diaphragm (16) is at least doubled by subjecting the anisotropically etched cavity (14) to a mild isotropic etch. This substantially improves the cavity-side over-pressure rating of the finished pressure sensor (10) without any significant change in the device sensitivity or allows higher sensitivity to be obtained for the same over-­pressure rating or intermediate combinations thereof.
