Title: Thermal recording apparatus
Inventor: SHIMAMURA YOSHIYUKI
IPC: B41J2/36
Filed: 1986-11-05
Abstract: PURPOSE:To rapidly check a recording image by eliminating necessity for adjusting a density volume each time, by constituting the title apparatus in the manner that the recording image is checked while density is automatically changed to effeet recording. CONSTITUTION:A CPU 21 inputs the order signal and data signal from a host 22 such as an office computer or a word processor, and motors and the heat generating elements of a recording head 4 are driven on the basis of said signals through a driver 23. When the checking of a recording image is started, density (n) is set to 1 at first and the heating time to the density (n) is subsequently determined from the density/heating time table stored in ROM to record one line. Next, the density (n) is raised by one step to record the next line. As mentioned above, since a check pattern is recorded when the recording image is checked while density is automatically changed by one line along a program, necessity for manually adjusting a density volume each time is eliminated.

Abstract: PURPOSE: To obtain a fully extended scope of irradiation of a particle beam by controlling the charged particle beam to be flat and moving it at a right angle to the flat surface to irradiate it to a prescribed target scope. CONSTITUTION: A particle beam arrives at the irradiation target 20 by way of converging 4-polar magnet 13, diverging 4-polar magnet 14, 8-polar magnet 21, deflecting magnet 11, 2-polar magnet 23, etc. The converging 4-polar magnet 13 makes the particle beam converge by changing grade resistance of the orbit of the beam with the force in proportion to the variation in the X direction when the variation in the X direction is large, and as for in the Y direction, it makes the beam diverge with the force in proportion to the variation in the Y direction. On the other hand, the diverging 4-polar magnet 14 gives the beam the acts contrary to those given by the converging 4-polar magnet 13. Therefore, the particle beam is diverging in the direction parallel with the deflection surface and is converging in the vertical direction as it comes nearer to the irradiation target.  The distribution of the particles in the defection surface is flattened at the irradiation target 20 as the particle beam goes through the 8-polar magnet 21.
