Title: Inclined magnetic field coil
Inventor: FUJIO YASUO
IPC: A61B5/055
Filed: 1986-03-31
Abstract: PURPOSE:To contrive the reduction of a sound generated by Lorentz power by increasing an output efficiency by enlarging a linear space of an inclined magnetic field by specifying a way of winding wires on four coils composing an inclined magnetic field coil. CONSTITUTION:Each of four saddlebacked coils 1 is formed by winding one wire by n-turns so that its are parts of both center side (CA) and end side (EA) are composed of n-pieces wires 11-1n and wires 21-2n, respectively. Also, a straight part parallel to a z-axis is composed n-pieces. The expanding angles of said arc parts theta1-thetan are different from one another and the positions of the wires 11-1n of the center-side are parts are different mutually. Distances Z1, Z2,... Zn from a center original point are changed. The strength of an inclined magnetic field is determined mainly by the wires 11, 12 etc. on the center side and the correction of a magnetic field uniform space is effected by the wire 1n etc. remoter from the center. Consequently, it becomes possible to reduce the number of turns, an area of the coil, and an inductance of the coil while enhancing a uniformity of an inclined magnetic field and a linear space.

Title: Vane control device for movable vane fluid pump
Inventor: YAMADA MASAYUKI
IPC: F04D29/18
Filed: 1985-04-10
Abstract: PURPOSE:To reduce a load on a thrust bearing by using a material of small coefficient of friction for each slide surface of a bearing for the support of a movable vane axis and a link mechanism for connection between a vane control rod and the said vane axis, and locating the center of a movable vane stem at a specific position. CONSTITUTION:A material having a small coefficient of friction is used to from the slide surfaces of a bearing 50 to support the axis 6a of a movable vane 6, and a link mechanism 70 connecting a vane control rod 3 to the said axis 6a. Also, the center of a stem is positioned to the trailing side of a movable vane 6, relative to the center of water pressure P, so that the moment of rotation M (P.l) arising from a deviation between the centers of the water pressure and the stem will be made small. Then, the relations of F-X 0 and W1+W2>X+F become thereby available, when W1=water thrust, W2=motor rotor load, X=axial force corresponding to rotary vane force due to water pressure and F=axial force due to friction between the bearing 50 and the link mechanism 70. Consequently, the load of a thrust bearing 22 at the side of a motor 8 can be substantially reduced at the time of control for opening and closing the valve.

IPC: B41J2/51
Filed: 1980-06-04
Abstract: PURPOSE:To provide a recorder capable of providing various recorded print styles using one printing head and one letter signal generating circuit, by enabling the printing head to be rotatable in a plane parallel to a recording surface.

Title: Horizontal shaft pump
Inventor: MIZOBUCHI SHOTARO
IPC: F04D29/041
Filed: 1985-04-10
Abstract: PURPOSE:To support a thrust load in both normal and reverse rotations of a horizontal shaft pump by providing an intermediate disc having a spiral groove on its upper surface formed in a direction for causing a dynamic pressure effect in normal rotation and another such groove on the lower surface in a direction for causing the same effect in reverse rotation, between a rotary bearing disc and a fixed bearing disc. CONSTITUTION:Between a rotary bearing disc 36 and a stationary bearing disc 38 is inserted an intermediate disc 39 of ceramics, etc. comprising spiral grooves 47 and 47' formed in such a direction that a dynamic pressure effect is given in normal rotation by the groove on the upper surface and the same effect is given in reverse rotation by another groove on the lower surface. By this constitution, when the rotary shaft 11 is turned in arrow direction, a flow in an arrow A direction is caused on the surface of the intermediate disc 39. Then, this disc is made in close contact with the stationary disc 38 and a fluid film is formed between the surface of the intermediate disc 39 and the rotary bearing disc 36 to support a thrust load. In the reverse rotation, the intermediate disc 39 is attracted by the rotary bearing disc 36, and both discs rotate all together, thereby forming a dynamic pressure effect between the back of the intermediate disc 39 and the stationary bearing disc 38. In this instance, the intermediate disc 39 is not penetrated by a shaft, and it is possible to obtain a large dynamic pressure effect and make the pump compact.

Title: Wafer circumference aligner
Inventor: SUMIYA MASATO
IPC: H01L21/027
Filed: 1989-03-29
Abstract: PURPOSE:To make it possible to sharply remove a resist from the boundary between a pattern- formed part and the circumferential part of a wafer by a method wherein the angle of the segment linking the optical axis of the image-forming lens located at the edge part of the light-emission end face of a light guide fiber, the center point of a wafer and the incidence point of the optical axis is set at the prescribed acute angle. CONSTITUTION:Strands are tied up in a bundle in such a manner that the light-emission end face 3a of a light guide fiber 3 is formed in a square. The optical axis of an image- formation lens 5 is brought in coincidence with the straight line linking the outside end part of a wafer against its center line of the light-emission end face 3a of the light guide fiber 3, the pattern forming part of the wafer 1 and the boundary 1bt between the pattern forming part of the wafer 1. Besides, the angle Q of the segment, linking the optical axis of the image-forming lens 5, the center point of the wafer 1 and the incidence point of the optical axis, is constituted in such a manner that it becomes the prescribed acute angle. Accordingly, after a light has been reflected by the wafer 1, the light reflected again by the image-forming lens 5 is not projected on the pattern forming part, and as the optical axis of the image-forming lens is located on the boundary 1bt, the boundary of the pattern forming part of the wafer 1 and its circumferential part can be exposed sharply. As a result, the resist on the circumferential part of the wafer can be removed clearly.

Title: Production of artificial fine aggregate
Inventor: TAKEDA KAZUHISA
IPC: C04B18/10
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain an artificial fine aggregate having comparable effect with natural sand by making a tacky water-dispersible resin adhere to the surface of the coarse granular ash in coal ash and also by making the fine granular ash in the coal ash adhere to the water-dispersible resin. SOLUTION: Coarse granular ash is bottom ash, cinder ash or the like having been discarded and disposed of because of its low quality, among coal ash discharged from e.g. coal single firing boilers. A water-diluted resin is pref. a latex emulsion or polybutene emulsion which is prepared by diluting a resin with water so as to be 0.5-5 wt.% in resin content. Fine granular ash is charged, together with the coarse granular ash sprinkled with the water-diluted resin, at 50-500 l/m<3> per m<3> of the coarse granular ash, followed by agitation, thereby being sprinkled on the surface of the coarse granular ash to effect adhesion; thus obtaining the objective artificial aggregate having smooth surface and improved in physical properties.  Compared with crushed sand, this artificial aggregate requires no excessive unit amount of water for conferring fluidity on concrete, therefore no crack develops in hardened concrete compounded with this artificial aggregate, leading to obviating relevant industrial waste disposal sites.

Filed: 1993-03-09
Abstract: PURPOSE:To make it possible to charge a secondary battery which has a higher voltage than that of a solar battery with large current regardless of solar battery current by charging it using pulse discharging of a capacitor. CONSTITUTION:A primary circuit of a ringing choke converter is constituted of a series circuit of a solar battery S used as a power supply, a back-flow proof diode D1, a primary coil N1 of a transformer T1, and a main switching element Q1.

Namely, when a controller 15 calculates a value less than a minimum time required to rotate the toner supply motor 16, this value is stored in the controller 15 and when a signal longer than the minimum time is outputted to the toner supply motor 16, the stored value is added to the signal and the resulting signal is outputted to the toner supply motor 16. Consequently, toner corresponding to the toner consumption during development is supplied to a developing device.
