Title: Apparatus for compression encoding video signals
Inventor: YAMADA TAKAAKI
IPC: H04N19/91
Filed: 1992-12-24
Granted: 2003-05-13
Abstract: Apparatus for compression encoding video signals, comprising block segmenting means for segmenting a vertical interval, such as a field or frame, of video picture elements into a plurality of blocks of picture elements. An orthogonal transformation, such as discrete cosine transformation, of respective blocks is obtained, resulting in a two-dimensional array of transform coefficients of different values, the array being partitioned into respective areas. Each area is quantized with a respective quantizing value that differs for different areas. Preferably, a transform coefficient is quantized by dividing the value of the transform coefficients in an area by a divisor 2n/2, where n is an integer that differs in different areas. The areas of the two-dimensional array of transform coefficients are formed by partitioning the array in a direction substantially perpendicular to the oblique frequency axis of that array.   -i-

Title: Procedure and apparatus for feeding a material into a pressurized space
Inventor: KILPELAINEN REIJO
IPC: C10J3/30
Filed: 1993-03-23
Granted: 1995-12-05
Abstract: The invention relates to  a procedure and an apparatus for feeding solid material into a pressurized space.  The apparatus includes a feed chamber communicating with the pressurized space via a gate.  A piston cylinder which adjoins the feed chamber has an aperture in its wall for the intake of solid material.  A piston assembly, which consists of an inner and an outer piston, moves within the piston cylinder and closes the feed chamber tightly when in its forward position.  The inner piston moves inside the outer piston, and in the feed chamber, to force the solid material into the pressurized space.  In operation, solid material is supplied into the feed chamber through the aperture in the wall of the piston cylinder while the piston assembly is in its rearward position.  The piston assembly is then thrust forward so that the feed chamber is tightly closed, and the gas pressure in the feed chamber is adjusted to correspond to that in the pressurized space. Finally,  the  gate  between  the  feed  chamber  and  the pressurized space is opened, and the inner piston thrust into its forward position to force the solid material into the pressurized space.

Title: Lockable handle
Inventor: HOFFMAN ERNEST G
IPC: H01H9/28
Filed: 1993-04-20
Granted: 2003-08-19
Abstract: A housing contains a device such as an electrical switch and a handle is mounted on a cover of the housing.      The handle is rotatable between first and second positions.      The handle is coupled to the device within the housing so that when the handle rotates, the device is changed from one state to another. An annular wall partially surrounds the handle, the wall having end faces which limit the rotational movement of the handle. The wall and the handle have holes which can be aligned in one position of the handle and held in that position by inserting the shackle of a lock. With this structure, a switch can be locked in an off or on position to inhibit unauthorized changing of the switch position.

Abstract: A satellite tracking antenna system comprises three or four plane antennas juxtaposed on a single plane.          A first and a second antenna are juxtaposed in an azimuth direction, and a phase difference between signals received by these antennas is detected in order to determine a declination of an antenna unit with respect to the satellite as viewed in the azimuth direction.  The first and a third antenna are juxtaposed in an elevation direction, and a phase difference between signals received by these antennas is detected to determine a declination of the antenna unit with respect to the satellite as viewed in the elevation direction.  The antenna unit is driven so as to reduce these declinations to zero.  Stated differently, values of a sine and a cosine function are extracted which have a phase difference between signals received by a pair of antennas as a parameter, and a tangent value representing the ratio therebetween is calculated and is then inversely converted to provide phase difference information.

Abstract: Methods for processing samples which may contain mycobacteria which are compatible with both conventional culturing techniques and nucleic acid analysis. It has been found that the harsh chemical treatment previously thought necessary to obtain efficient lysis can be eliminated without loss of lysis efficiency, thereby eliminating reagents which may inhibit subsequent nucleic acid-based reactions. Heat alone is sufficient to lyse mycobacteria, even in buffers which do not contain detergents, chelators, enzymes, etc.  Residual reagents introduced by conventional sample processing methods for culture can be successfully removed from the processed pellet without significant loss of microorganisms by at least two washings with saline, water, or buffers compatible with nucleic acid analysis and appropriate centrifugation.

Abstract: A system or structure allowing conversion of the front area seating of a van to a dinette for two and/or four persons and to a single and/or double bed.   The structures provided  enable the front passenger seat to rotate 360 degrees and slide over a position adjacent to the driver seat which also can be rotated 360 degrees. The single seat directly behind the driver seat can be extended sideways to form a double seat.   The table in between the front seats and seat directly behind these seats is cantilevered from a wall cabinet located below the window,  which is located in the exterior sidewall directly behind the driver seat.  This table is removable at will for storage in a coat closet or lowered to serve as a base for a single or double bed.  The two part hinged front leaf may be folded back over the main rear leaf to allow ample space for the driver seat to slide back and forth on tracks when in the forward driving position. When the table is lowered to the bed base position, the rear seat cushion(s) is moved forward thereby resting on the lowered table.  The back rest(s) is lowered into the location of the seat cushion.   The two front seats are rotated to face one another with the passenger seat slid over to a position directly adjacent the driver seat.  The arrangement makes for a double bed or a single bed if only the driver seat and the cushions (without the extensions) of the rear seating are used.

An adaptive code book is referred to based on the perceptual sensitivity weighted error signal sothat an adaptive code vector and a pitch period is selected.  Also, an excitation code book is referred to based on the perceptual sensitivity weighted error signal so that an excitation code vector is selected.  In a gain code vector section having a gain code book which stores gain code vectors, a gain code book is referred to based on the perceptual sensitivity weighted error signal, so that again code vector is selected.  Gains are determined from the selected gain code vector in units of time intervals shorter than the sub-frame, and a reproductionsignal is generated by weighting the adaptive code vector and excitation code vector with the determined gains within units of the time intervals.

Abstract: A method and apparatus for making reusable paint rollers comprised of a core formed of thermoplastic material. The core is formed by helically winding one or more strips of thermoplastic material about a stationary mandril. A layer of adhesive is then applied to the outer surface of the core whereupon a cover, applied as a strip of material or as blown on fibers, is bonded thereto. The core may also be formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril.  The paint roller may also be made by bonding, in a single step, the fabric cover to the wound strip wrapped about the mandril. The cover is then pressed onto the core to form a tight and secure bond therebetween. The mandril may also be cooled to speed the production process.
