Title: Hybrid stepping motor, driving method for the same and coil winding method for the same
Inventor: MIYAZAWA SADAO
IPC: H02K37/18
Filed: 1993-07-30
Abstract: A ten-phase and twenty-main-pole hybrid stepping motor is driven by a five-phase driving pulse. The rotor has N and S pole toothed gears (2) at ends of a rotor shaft (8). The stator (4) has a cylindrical hollow body (4a). Nos. 1-20 main poles extend from an inner wall of the hollow body toward the rotor shaft in a plane perpendicular to the rotor shaft so that the twenty main poles surround the N and S pole teeth in the plane perpendicular to the rotor shaft. Each main pole has a free end at which two statorteeth are formed. The stator teeth face the teeth of N and S pole teeth gears. A coil is wound around each main pole for excitation of the main pole. Nos. 1-10 main poles and Nos. 11-20 main poles face each other in the radial direction of the rotor respectively. An arbitrary main pole and a fifth next main pole always have a 90-degree relation. Positions of the teeth on Nos. 1-10 and Nos. 11-20 main poles are respectively determined by:        Pt x k + m x  THETA where Pt is the rotor tooth pitch; r is the magnitude of the stepping pitch,  THETA  is an arbitrary integer (different for each pole) between 0 and 9, k is an arbitrary integer between 0 and K-1; and K is the number of N pole teeth. A method for winding the coils is also disclosed. <IMAGE>

Title: Periodontal dosage form
Inventor: TODDYWALA ROHINTON
IPC: A61K9/00
Filed: 1993-12-10
Abstract: A periodontal dosage form comprises a drug containing layer having top and bottom surfaces, and side edges around its periphery where the side edges are substantially free of applied coverings. Directly an the top and bottom surfaces of the drug containing layer are polymeric layers comprising a physiologically acceptable, bio-erodible polymer composition capable of diffusing a drug through it from the drug containing layer when the dosage form is positioned in a periodontal pocket. In use, the patient receives an initial dosage via the side edges of the drug containing layer. Prolonged administration is achieved through slow diffusion through the polymeric covering layers.

Title: Apparatus for separating liquids from solids
Inventor: HOARE DAVID ARTHUR
IPC: B01D29/11
Filed: 1993-12-31
Abstract: An apparatus for separating liquid and solid components of a sludge or slurry such as animal manure comprises a wall array of upright pillars (10) separated by straining gaps (17) through which the liquid content of the slurry is strained. The pillars (10) comprise PVC pipes filled with concrete (18) and capable of building up an electrostatic charge. The pipes 10 are mounted in an electrically conductive metal framework (11) so that the electrostatic charge is earthed through the framework (11). The electrostatic properties of the apparatus improves the colloidal separation of liquid and solid components of the slurry. The pillars may form an annular array defining a space into which liquid strains from a slurry pit. Alternatively a straight row of pillars forms one wall of a tank, otherwise made of concrete, which contains the slurry, and liquid strains out between the pillars. <IMAGE>

Title: Dynamic visual representation of simulated circuit information
Inventor: MALM RICHARD LAVERNE
IPC: G06F17/50
Filed: 1994-03-02
Abstract: An improved technique for processing large amounts of information and displaying that information graphically. The graphic display focuses attention to suspect areas employing colours and shading techniques to quickly focus the users attention to problem areas. The display shows selected net states across respective raster lines e.g. N21, N20 etc for a selected period of a VLSI circuit simulation. As the net states changes between logic 1, logic zero or an undefined state, the colour of the raster line changes. The large number of nets which can thus be displayed and the time sequence of changing states can enable rapid evaluation of the VLSI circuit performance and the existence of errors or faults in the design. <IMAGE>

IPC: B65H3/08
Filed: 1994-08-09
Abstract: A valve comprises first 1 and second 2 valve members located in a bore in a housing 3. Member 1 is prevented from rotation in the bore by a pin 5 locating in a slot 6. Member 2 is secured to member 1 by a bolt 4 but may rotate relative to member 1. An air cylinder 8 moves members 1 and 2 along the bore to expose blowing-air opening 18 to line (17, figure 2) and suction-air opening 13 to line (14). With cylinder 8 fully retracted the valve is set using adjuster 11 such that a small amount of blowing-air escapes through an opening 12. The member 2 has a gear 20 attached to its end so that it may be rotated relative to member 1 by a gear 21 driven by a motor 24, to control the amount of blowing air. The valve is for use with sheet feeders. Members 1 and 2 may be moved by an electromagnetic device rather than air cylinder 8. A potentiometer 25 may be provided between motor 24 and gear 21. <IMAGE>

Title: Vehicle body structure
Inventor: HONMA MASAYUKI
IPC: B62D25/20
Filed: 1995-08-30
Abstract: A side body structure of a motor vehicle includes first (6) and second (6') crash boxes at the connecting portion of a side sill (1) and a rear wheel arch (2). The first crash box (6) is provided outside of a side sill reinforcement (13) and the second crash box (6') is inside the side sill reinforcement. The second crash box (6') is connected with a cross member (9) extended in a transverse direction of the vehicle. In an event of a side impact, first the first crash box (6) collapses and then the second crash box (6') collapses. Finally, the impact energy is transferred to and absorbed by other body structures through the cross member (9). Thus, the side sill portion (1) and the rear wheel arch portion (2) can be prevented from intruding into a rear compartment so as to save passengers from serious injury. <IMAGE>
