Abstract: PURPOSE:To eliminate jitter on an image caused by the fluctuation of the intensity of a laser beam by providing a light quantity suppressing means for attenuating the intensity of the laser beam which reaches an image writing area. CONSTITUTION:Light from a semiconductor laser 1 is condensed 2, made incident on a rotary polygonal mirror 4 through a cylindrical lens 3, deflected by the mirror 4 which is rotated at a high speed, and formed into the image on the electrostatically charged surface of a photosensitive drum 8 by an ftheta lens 5 through a mirror 6 and an ND filter 7. As soon as the image formation spot of the laser beam is repetitively moved in a direction shown by an arrow X by the rotation of the mirror 4, the photosensitive drum 8 rotates in a direction shown by an arrow Y. The laser beam from a semiconductor laser 1 is made incident on a photodetector 9 to generate a synchronizing signal (d), and the intensity of the laser beam is attenuated by the ND filter 7 having an attenuation factor. Then, an electrostatic latent image is formed with the attenuated laser beam, so that the image having excellent gradation characteristic without the deviation of synchronization detection is formed.

Title: Method for supplying dampening agent to plate of offset press
Inventor: ANTON ROODEI
IPC: B41F33/00
Filed: 1993-12-28
Abstract: PURPOSE: To avoid an irregularly formed printed original and/or an emulsification in an inking unit by a producing process for a long time by alternately hanging a supplying amount of a dampening solution to above or below a preselected mean value, and adjusting both or one of the minimum and maximum of the mean value. CONSTITUTION: An amount of a dampening solution to be supplied is presented at a maximum value Max or a minimum value Min, and hence alternately changed from a mean value M as a center. Here, the change from the Max to the Min or vice versa is discontinuously executed. A period of supplying the solution changing in amplitude M to the Max, Min is regulated by a printing worker according to a step of the original with respect to the length and the width of a printing image. In this case, since the worker roughly regulates it, he selects the minimum value Mi substantially corresponding to the solution supply amount necessary to completely print the surface of the print image when continuous supply of the solution is used. The maximum value Max is selected corresponding to the supply amount necessary according to the original when the maximum value Max is continuously supplied.

Title: Variable displacement pump
Inventor: HAINRITSUHI NIKORAUSU
IPC: F04B49/08
Filed: 1989-12-26
Abstract: PURPOSE: To enhance the multiusability in a hydraulic system by arranging the control valve associated with respective load preceding consumers to a location where a signal is sent to a pump regulating means so as to meet the requirement in the delivery rate. CONSTITUTION: When the increase in the delivery rate of a variable displacement pump 1 preceding the load is required by, for instance, a consumer 3, a pressure compensation valve 15 is moved to the maximum open position, so that a control pressure signal 16 regulates the pressure in the chamber 28 of the pump control part via lines 20, 22 and a pump control valve 30, and a piston 26 is moved to the maximum delivery side by a spring 27. When the requirement in the delivery rate of the pump 1 is satisfied, the control port of the pressure compensation valve 15 is closed, and the opening of a restriction 24 for releasing the pressure to a reservoir T is decreased. Further, the pump control valve 30 is made controllable even by an electric signal. Thus, the multiusability of a hydraulic system can be substantially enhanced.

Title: Hydraulic control device of continuously variable transmission for vehicle
Inventor: SUGAYA MASAMI
IPC: F16H61/00
Filed: 1989-12-25
Abstract: PURPOSE:To obtain suitable speed change responsiveness by applying urging force of a gain change spring of a speed change control valve to act on a spool valve piece being based on a control oil pressure and setting a moving amount of the spool valve piece such that the higher is a car speed the smaller the moving amount of the spool valve piece is made. CONSTITUTION:In a speed change control valve 330, urging force of a gain change spring 360 acts on a spool valve piece 350 being based on a control oil pressure Psol1 by a gain change means comprising a return spring 358 and a piston 362, and the higher is increased a car speed the smaller a moving amount of the spool valve piece 350 is made. In this way, sensitivity of the spool valve piece 350 is decreased by the control oil pressure in a minimum value side region of speed change ratio where control responsiveness of speed change ratio is essentially made easily sensitive. Thus, suitable speed change responsiveness can be obtained over a total car speed change range.

Title: Nuclear magnetic resonance tomographing device
Inventor: GIYUNTAA RIISU
IPC: G01R33/20
Filed: 1990-11-30
Abstract: PURPOSE: To reduce the peripheral edge distortion of a tomographic image for a subject body to be inspected by equipping each inclining coil of flat form with correcting coil for removing the peripheral edge errors in the X and Y inclinations. CONSTITUTION: A coil device 11 is embedded in a recess formed at magnetic pole surfaces 7 and 8 and is equipped with inclining coils 12 of flat form for the x-, y-, and z-inclinations. Among them, the x- and y-inclining coils are fitted with correcting coils 30. The inclining coil 12 consists of two segments 14 and 15 connected in series, and the magnetic field error resulting from finite expand of the coils 14 and 15 is originated from the fact that the magnetic field is smaller than the ideally inclined magnetic field on the air gap center surface shown by the dash and dot line and is excessively large at the peripheries of the magnetic pole surfaces 7 and 8. This error is reduced by the correcting coils 30 to an harmless level.
