Title: Controlling method for scherbius equipment
Inventor: SASA CHIKAGE
IPC: H02P23/00
Filed: 1990-11-30
Abstract: PURPOSE:To cut out an accident current when cutting out the current of a short-circuit accident occurred at the primary side of a wound-rotor induction machine by turning on/off a switching element in response to the value of secondary current, superimposing a DC component to the secondary current and creating a zero cross point for the primary current. CONSTITUTION:When a U-phase secondary current becomes larger than zero, the output of an AND circuit 46 becomes '1' and GTO 15 is turned on. At this time, the secondary current flows from the secondary U-phase to GTO15  diode 10   returning to the secondary V-phase thereby acting in the direction for increasing the secondary current, so that U-phase current is shifted to the positive direction. Then, when the U-phase secondary current reaches the value of GTO controllable current, then U-phase GTO ON signal becomes '0' and GTO 15 is turned off. The U-phase secondary current and W-phase secondary current are shifted to the positive side, and the V-phase secondary current is shifted to the negative side. In this way, a zero cross point can be created in the primary current by superimposing a DC component to the secondary current of a wound-rotor induction machine 1.

Title: Compressor
Inventor: KAZAOKA KENICHI
IPC: F04C18/32
Filed: 1988-12-29
Abstract: PURPOSE:To decrease a slide speed of the forward end of a vane and reduce a friction resistance by changing a contact line of a rotor outer circumferential surface with a cylinder inner circumferential surface continuously along the circumference and changing the volume of a chamber connected with a discharge port. CONSTITUTION:If an eccentric shaft 22 rotates right about a point A, a chamber 38 expands, while a chamber 37 contacts inversely, and gas is sucked from a suction port 45 to a chamber 38, and a rotor 15 rolls along an inner circumferential surface of a cylinder 10 to move along a contact line in the direction of the circumference, so the chamber 37 gets into a compression process. During this move, a vane 18 moves gradually to a discharge port 42, and compression gas in the chamber 37 starts to be discharged from the discharge port 42, and the volume of the chamber 38 is further increased. During the time, there is only a little motion of the rotor 15, and the vane 18 moves in the radial direction of the cylinder 10 only a little as well. Next the contact line moves from a left position to the side of the discharge port 42 to repeat suction and compression, while the forward end of the vane 18 reciprocates only for a distance. Friction resistance is thus made small and the compressor can be compact.

Abstract: PURPOSE: To shorten the construction term and to reduce the processing cost, by superposing an inner net and an outer net at a specific interval, setting the mesh size of the outer net smaller than that of the inner net, and setting the rigidity of the inner net stronger than that of the outer net. CONSTITUTION: A molding box 10 made by installing an inner net 11 and an outer net 12 to the outer side of a reinforcement member 21 is provided, and the molding box 10 is held by the reinforcement member 21 by placing a little larger size of spacers 13 between the reinforcement member 21 and the molding box 10. Then, a ready-mixed concrete is placed in the molding box 10, and the concrete is supported by the rigddity of the reinforcement member 21 and the molding box 10. In this case, the placed concrete is made in a large particle lump layer making a rough aggregate as the center inside the inner net 11. Furthermore, the component of the concrete permeating through the large particle lump layer forms a small particle lump layer making a small aggregate as the center inside the outer nut 12. Consequently, a large amount of flowing out of the concrete is blocked effectively by the meshes of the nets 11 and 12, and also by the lump layers formed at the inner sides of the nets 11 and 12.
