Abstract: The present invention provides a magnetic steel sheet containing, on a weight basis,  0.2 to 6.5% of Si and 0.03 to 2.5% of Mn,  having a crystallographic texture wherein the density of aggregation of {100} planes parallel to the surface of the sheet is not less than 10 times that of non-oriented crystal grains. and having a demanganized layer in which the concentration of manganese decreases from the interior of the sheet toward the surface of the sheet, wherein the ratio between the concentration of manganese in the surface portion of the sheet and that in the mid depth portion of the sheet is not more than 0.90 and wherein the maximum ratio of reduction in the concentration of manganese within the demanganized layer is not more than 0.05 wt%/ µm.  Magnetic characteristics of the magnetic steel sheet are further improved by adopting the average grain diameter 0.25 to 10 times the thickness of the sheet and by applying to the sheet a tension smaller than the elastic limit of the sheet in a direction parallel to the surface of the sheet.  By employing an appropriate ratio of reduction in the Mn concentration, a relatively high magnetic flux density is obtained without a sharp increase in magnetic flux density. and core loss reduces, thereby providing a non-oriented or doubly oriented magnetic steel sheet having excellent magnetic characteristics and blanking performance.

Title: Apparatus and method for establishing acquisition of spreading code in cdma transmission system
Inventor: HIGUCHI KENICHI
IPC: H04B1/707
Filed: 1995-12-27
Granted: 2000-05-30
Abstract: A CDMA system capable of quickly establishing acquisition of a long code, a spreading code with a period considerably longer than a symbol length.      The received phase of the long code is estimated by inserting an a priori code into a spread signal which is spread by the long code at a fixed interval, and by detecting the start timing of receiving the a priori code, where the a priori code has a correlation value of nearly zero with the long code, and an autocorrelation value of a triangular profile. Its transmitter has an a priori code inserting circuit, and its receiver has a replica generating circuit of the a priori code. In addition, the system includes a plurality of correlators for obtaining correlation values between the received signal and the replica of the a priori code, and a circuit for obtaining the maximum correlation values and their start timings of reception among these correlation values. It estimates the start timing of the a priori code from the start timings of reception that provides the maximum correlation values, and estimates the point separated by a fixed time from the estimated start timing to be the received phase of the long code.

Title: A control system for a vertical vane covering for architectural openings
Inventor: ANDERSON RICHARD N
IPC: E06B9/36
Filed: 1997-09-30
Granted: 2006-11-14
Abstract: A control system for a vertical vane covering for an architectural opening includes a new and improved symmetric headrail having uniquely designed carriers for suspending individual vanes wherein the carriers are designed to minimize skewing relative to a tilt rod as they are moved along the headrail. A pantograph system is utilized to interconnect the carriers, and is connected to the carriers in alignment with the tilt rod so as to minimize skewing. The carriers have pockets formed therein through which the traverse cord extends so that the traverse cord, which moves the carriers along the tilt rod, is secured to a lead carrier closely adjacent to the tilt rod to, again, minimize skewing.      Light blocking rails are also attachable to the headrail to substantially bridge the gap between the headrail and the top of the suspended vanes to prevent light from passing therebetween. The tilt rod is keyed to gears in the carriers to facilitate assembly of the control system with all vanes properly aligned.

Abstract: Xylanase DNA is recovered from soil by PCR amplification using degenerate primers. Because of the complexity of the soil samples, it is likely that the recovered product will include more than one species of polynucleotide. These recovered copies may be cloned into a host organism to produce additional copies of each individual species prior to characterization by sequencing.  Recovered DNA which is found to vary from known xylanases can be used in several ways to facilitate production of novel xylanases for industrial application. First, the recovered DNA, or probes corresponding to portions thereof, can be used as a probe to screen DNA libraries and recover intact xylanase genes including the unique regions of the recovered DNA. Second, the recovered DNA or polynucleotides corresponding to portions thereof, can be inserted into a known xylanase gene to produce a recombinant xylanase gene with the sequence variations of the recovered DNA.

Granted: 2002-10-29
Abstract: A new Soffit Mounted Dryer Vent for offering a non-maintenance exhaust vent system for a clothes dryer vent that terminates in a soffit of a roof overhang. The inventive device includes a flange, a dryer hose adapter ring, an outlet fitting, and a vent flapper.     The flange has an air passage, an upper surface, and a lower surface.     The air passage allows exhaust air to pass through the flange from the dryer hose adapter ring to the outlet fitting. The dryer hose adapter ring is symmetrically mated to the upper surface of the flange. The dryer hose adapter ring has an outer wall diameter of substantially the same dimensions as the clothes dryer vent hose thereby allowing the clothes dry vent hose to matingly slip over the dryer hose adapter ring.     The outlet fitting, having an outlet opening, is adjoiningly mated to the lower surface of the flange. The vent flapper is pivotally attached to the outlet fitting at the outlet opening.      In use, the clothes dryer vent hose is slipped over the dryer hose adapter ring. The flange is attached to a soffit of a roof overhang by a fastener, such as a screw or a nail. Exhaust air from the clothes dryer vent hose flows through the dryer hose adapter ring, through the air passage of the flange, and through the outlet fitting.    The force of flowing exhaust air causes the vent flapper to pivot outward allowing exhaust air to exit through the outlet opening of the outlet fitting. When no exhaust air is flowing, a flapper stop prevents the vent flapper from pivotally rotating into the outlet fitting beyond a substantially vertical plane.
