Patent EP-0095685-A2 (EP)
Inventor: JACOBS PAUL H
IPC: H04B1/68
Filed: 1983-05-20
Abstract: A compressed single side band communication system and method in which the audio signal is compressed prior to pre-emphasis and thereafter summed with a pilot tone for further compression prior to transmission. Initially, only the pilot tone is transmitted at full rated power to aid in acquisition of the signal by the receiver. Thereafter, the transmitter ALC is disabled and the pilot tone is attenuated. The receiver adjusts the frequency characteristics of the pilot tone filter and phase lock loop filter in the detector as a function of lock-on. The delay after loss of lock-on in reverting to wide band pilot tone and wideband loop filters is varied as a function of signal strength. The pilot tone may be modulated for tone coded squelch. The modulating source is located in the return end of the phase lock loop filter. A unique filter is provided to insure acquisition of the pilot tone. Automatic gain control of the audio signal is responsive to the tone signal without affecting the composite audio and tone signal.

Abstract: A technique is disclosed to prevent dielectric breakdown of a thin gate insulating film (14b) of a memory cell capacitor of a dynamic semiconductor memory device such as a dynamic random access memory. A diffusion layer (18) of an n-conductivity type is formed on a predetermined surface region of a semiconductor substrate (10) of a p-conductivity type so as to form a p-n junction. A polycrystalline semiconductor layer (16') which corresponds to a gate electrode and which is connected to the thin gate insulating film (14b) partially contacts the diffusion layer (18). Thus the polycrystalline semiconductor layer (16') is electrically connected to the substrate (10) through a diode region which is formed of the p-n junction. Abnormal charges stored in the thin gate insulation layer (16') is immediately discharged to the substrate (10).

Abstract: A two-step process is disclosed for preparing an essentially non-crossiinked random copolymer of acrylic acid or methacrylic acid with esters of the acids which esters are formed by reaction with an alkylene oxide. Raw materials are (meth)acrylic acid and alkylene oxide. in a first step, a predetermined amount of a particular esterification catalyst is used, and with close control of process conditions, the (meth)acrylic acid yields both mono- and polyalkoxylated esters. in the second step polymerization is effected without separating the esterification catalyst or purifying the esters formed. The resulting random copolymer formed consists essentially of a terpolymer of (i) acrylic acid or methacrylic acid (together "(meth)acrylic"), (ii) a hydroxymonoalkylated (meth)acryiate, and (iii) a hydroxypolyalkyleneoxylated (meth)acrylate the monomeric moieties being present in specified relative proportions. Despite the presence of the polyalkyleneoxylated ester moiety the terpolymer is soluble in water, and is surprisingly effective in the treatment of industrial process water used in recirculating water systems.

Abstract: @ There is disclosed a hand-held labeler having a print head with electrically selectable printing elements for printing and applying pressure sensitive labels. The labeler has a housing with a handle and structure for mounting a roll of pressure sensitive labels releasably carried on a carrier web. The labeler has a movable section which mounts a keyboard and a control circuit on a circuit board. The control circuit controls the printing elements. Labels are printed by the printing elements as the carrier web is advanced, and labels are delaminated at a delaminator and dispensed into label applying relation to an applicator. The print head is mounted on a support and is continuously spring-urged toward the platen. Movement of the print head toward the platen is limited to prevent damage. The support and the print head can be moved away from the platen from the outside of the labeler to facilitate threading of the web. The print head support can be skewed to provide uniform pressure contact of the printing elements with the labels. An electrical energy source, for example a battery, can be located in a hole in the label roll. Electrical energy from the battery terminals passes to the control circuit via contacts associated with the label roll mounting structure. In another embodiment, the handle can comprise a rechargeable battery. The drive includes an electrical stepping motor and in another embodiment, the drive is mechanically accomplished. 
     Printing is accomplished by a plurality of individually controllable printing elements, preferably arranged in a single line array disposed on the print head in a direction transverse to the direction of advancement of the web. The array may be only one character width or height long, or may extend across the entire width of the web, in order to permit any size characters of any font and any orientation to be printed. When a long array is used, a serial-to-parallel converter may be incorporated in the print head to reduce the number of connections that need be made to the head. By utilizing thermal printing elements, the characters can be made to appear as if they were formed of individual print elements, or as if they were continuously printed simply by controlling the length of time that the printing elements are engaged to thereby control the amount of smear and burn produced on the web.

Abstract: Stacks of generally dish-shaped, nested plastic articles are gripped and transferred from elevated, horizontally ad- jacentchutes comprising circumferentially disposed, axially extending supports, which are open at both ends to permit articles to be both fed thereto and removed axially therefrom, to a conveyor disposed at a lower level. A transfer arm, mounting stack gripping receivers, which pivot on the transfer arm, is swung in an arcuate path and the receivers are moved relative to the transfer arm, responsive to swinging movement of the transfer arm, such that the receivers travel from a first position, horizontally axially aligned with said chutes and axially intermeshed with the supports, in a path having a first axially linear increment, then a downward arc to rotate said stacks substantially 90°, and finally a vertically linear path to deposit the stacks on the conveyor. The receivers are radially contracted to peripherally grip stacks of articles in the chutes when the receivers are in the first position, and are radially expanded to peripherally release the stacks when the receivers have moved the stacks to the conveyor.
