Title: Linear motor
Inventor: SAITO SHOICHI
IPC: H02N2/00
Filed: 1993-12-08
Abstract: PURPOSE:To obtain a noncontact structure for transmitting linear driving force by fixing an electromagnet to the free end of a telescopic member oppositely to a moving member through a gap and moving the moving member with a control current being inputted. CONSTITUTION:A telescopic member 81 fixed to a frame 80 is fixed, at the opposite free ends thereof, with electromagnets 82, 83. The electromagnets 82, 83 comprises coils 82b, 83b wound around cores 82a, 83a fixed to the free ends of the telescopic member 81. A moving member 84 is provided oppositely to the electromagnets 82, 83 through gaps. The telescopic member 81 is telescoped with a control current to move the electromagnets 82, 83 integrally. When the control current is fed to the coils 82b, 83b, the electromagnets 82, 83 attract the moving member 84 while keeping a gap between the cores 82a, 83a. The attracting force is combined with the action of the free end of the telescopic member 81 thus moving the moving member 84. This structure allows to transmit the driving force from the telescopic member 81 to the moving member 84 without requiring any mechanical contact structure.

Title: Digital-analog converting circuit
Inventor: KASUGA NOBUYUKI
IPC: H03M1/08
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the generation of glitch noise by tracking and holding the output of an analog signal generating part at the time of the change of the analog output of a heavily weighted signal source. CONSTITUTION:Different weights are given to signal sources G1 to Gn and an analog signal generating part 1 outputs an analog signal having a desired staircase form to deglitcher 3 in accordance with the combination of turning-on/off of switches S1 to Sn. A code change detecting part 4 is provided with a storage means like a resistor and monitors the change of a digital code D. The detecting part 4 tracks and holds the output of the analog signal generating part 1 by the deglitcher 3 when the code D by which heavily weighted outputs out of outputs of signal sources G1 to Gn are changed is given. Thus, the stepwise analog signal free from glitch noise is obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent unevenness and color shifts of an electrostatic image formed on the surface of an image carrier by designing a device so that the direction of a resultant force applied to the image carrier coincides with the direction of light to which the surface of the image carrier is exposed by an exposure means. SOLUTION: A photoconductor drum 8, to which a roller 41 is made to abut by an energizing means 42 so that the drum 8 is energized, is exerted with a resultant force which comprises an energizing force produced by an energizing means 42 with the rotation center of the photoconductor drum 8 serving as the center of the force, an energizing force which the photoconductor drum 8 receives as a transfer drum 15 is pressed into contact with the photoconductor drum 8, an energizing force which the photoconductor drum 18 receives as a cleaning device 16 is pressed into contact, and a gravitational force produced by the weight of the photoconductor drum 8.  In this case. the resultant force coincides with the direction of light to which the surface of the photoconductor drum 8 is exposed by a laser exposure optical system 11, and it works in an opposite direction to the direction from a mirror 11c to the photoconductor drum 8.

Filed: 1992-12-24
Abstract: PURPOSE:To allow the instinctive and easy use of a graphics preparation device by shifting the interest zone of a sector type trapezoid having a fixed center point, without any change in area and also without any substantial change in aspect ratio. CONSTITUTION:A graphic drawing section 25 draws circular arcs having radii (a) and (b) from center points X and Y at an angle of (alpha+ or -theta/2). Then, a line is drawn between the end points of respective circular arcs, thereby drawing a sector type trapezoid. In this case, assuming that the arc of the trapezoid has a length A, the area thereof is B, a radius difference (d) is equal to (b - a) and a mean radius L is equal to (a+b)/2, A=Ltheta and B=dLtheta result. Then, when the data of shifting positions (x) and (y) is entered via a mouse 26, the first arithmetic section 27 calculates an angle beta of the positions (x) and (y) with the center points X and Y. Also, the second arithmetic section 28 computes a distance L from the positions (x) and (y) to the center points X and Y. Thereafter, a setting section 29 establishes the angle beta at the center angle alpha. Then, the third arithmetic section 30 obtains the center angle thetaof the trapezoid from A/L, the radius (a) from (L -d)/2 using the difference (d) between the distance L and the radius, and the radius (b) from (L+d/2). The section 25 thereby prepares a shifted trapezoid.
