Abstract: PURPOSE:To do the next start surely by cutting, at an interval of 180 deg., the two places of the margin of the yoke consisting of a ferromagnetic substance in the vicinity of a rotor, to which four permanent magnets whose polarities are inverted are fixed, and driving the rotor with one driving coil. CONSTITUTION:Four fan-shaped permanent magnets 40 are arranged at intervals of 90 deg. on the circumference of a rotor 42, with their polarities inverted alternately, so as to form a rotor 4. Plural vanes 41 are planted radially on the other side of the rotor yoke 42 to constitute a fan. A stator yoke 6 is equipped with a cylindrical inner tube 6a adjacent to the inner margins of permanent magnets 40 and an outer tube 6b adjacent to the peripheries of the permanents magnets 40, and forms magnetic paths. Two cuts 7 with angles of about 80 deg. are made at symmetrical positions at intervals of 180 deg. in the outer tube 6b, and one side is provided with one driving coil 8, and the other side one hole element 9. Hereby, when the current application to the driving coil 8 is stopped, the rotor 4 stops at the specified position all times, and when a current is supplied to the coil 8, it is surely started in the specified direction.

Title: Image forming device
Inventor: MATSUURA MASAMI
IPC: G03G15/08
Filed: 1988-02-18
Abstract: PURPOSE:To obtain a sharp copy image which matches with the picture quality of a document and is different in image reproducibility by controlling the quantity of electrostatic charging of toner contained in a developer and varying the image reproducibility. CONSTITUTION:A toner electrostatic charging quantity varying means 30 varies optionally the quantity of electrostatic charging of toner which is conveyed cyclically by a developer circulation conveying means 24. Therefore, when a line drawing is emphasized, the quantity of electrostatic charging of the toner is increased and when a half-tone image is reproduced faithfully, the quantity of electrostatic charging of the toner is made larger than when the half-tone image is reproduced faithfully, by varying the image reproducibility. Consequently, the image reproducibility is varied over a wide range corresponding to the picture quality of an original image, and a sharp copy image is obtained.

Filed: 1983-03-04
Abstract: PURPOSE:To obtain an electric welded steel pipe having an excellent sour resistance characteristic without subjecting the pipe to a heat treatment by determining the width of a material in such a way that the elongation in the longitudinal direction of the pipe attains a specific value or below in the stage of forming the pipe. CONSTITUTION:The elongation epsilon3 in the longitudinal direction of a pipe is determined if a material width W0 is determined and therefore if the width W0 is so selected by a mathematical expression as to maintain <=1.5% the elongation epsilon3, the amt. of the hydrogen to be intruded into the steel is stabilized at a low level and the percentage length of a crack is decreased, by which an excellent sour resistance characteristic is obtd. The amt. of the hydrogen to be intruded into the steel depends largely on the tensile distortion during pipe forming but not much on the rate of the distortion at which the steel is bent as a pipe to a circular shape.

Title: Color balance adjustment method, program memory and digital camera
Inventor: FONTANI PAOLO
IPC: H04N9/73
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To improve color balance by sending a digital image including information about whether or not a strobo is used and a white balance coefficient as a header from the digital camera to a host and adjusting a color relative amount of each part of the image in the host so as to apply a prescribed color balance to the image thereby adjusting the compensation. SOLUTION: A host 121 reads a white balance coefficient from a header in an EXIF file format sent from a digital camera 100. Then presence of use of a strobo is discriminated and when the strobo is not in use, a coefficient is multiplied with a luminance of each image pixel and then the processing is finished. Image data are converted into an RGB format and each light source coefficient corresponding to each of three colors is calculated. When the strobo is in use, a strobo correction coefficient to compensate a data loss caused in the execution of automatic white balance is calculated in the camera 100 and the image where white balance is improved is formed based on each final data value in red, blue and green colors with respect to each pixel of the image.

Title: Soot blower device for rotary heat exchanger
Inventor: TAKAMA TOSHIHIDE
IPC: F23J3/00
Filed: 1984-02-24
Abstract: PURPOSE:To prevent damages to a heat accumulating mass as well as waste of superheated steam and air by arranging the angle between vanes which are attached to the periphery of a wheel with suitably uneven pitches and suitably modulating the length of respective vanes so that the pitch of movement of a blower may become constant. CONSTITUTION:When hoods 6a, 6b disposed at both free ends of a low-temperature side duct 1 which are opposed to a stator 3 are rotated in the direction of arrow (c), and a vane 18 of a wheel 16 comes in contact with a vane contact end 28 of an actuator 27 which is disposed in a high-temperature side duct 2, the wheel 16 is rotated by a large angle beta1 because the length of said vane 18 is the greatest. Therefore, even though a crank arm 25 and a connecting rod are away from each other to a maximum degree to be linearly aligned, the movement pitch P1 of the blower 9 becomes larger. When a vane 19 comes in contact with an end 23 thereafter, the wheel 16 rotates only by a small angle beta2 as the length of said vane 19 is the shortest. In this manner, the movement pitches P1, P2, P3 can be maintained constant.
