Abstract: PURPOSE:To obtain a rare earth doped glass enabling uniform dope of rare earth element and capable of simplifying production process by heating an aggregate of glass fine grains in a rare earth element compound gas atmosphere formed in a specific manner. CONSTITUTION:An atomized article of a rare earth element compound solution S is jetted from a nebulizer 13 and sprayed onto the surface of soot 11 rotating and simultaneously reciprocating in the vertical direction. Then the atomized article of the rare earth element compound is uniformly attached onto the surface of soot 11 by several reciprocations of the soot 11. The soot is dried in dried nitrogen stream, etc., to remove water content of soot. Then the soot 11 to which the rare earth element compound is attached is housed in a heating furnace 14 in which temperature gradient distribution in a closed state is formed, and then the heated rare earth element compound is sublimed.

IPC: H01Q21/06
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To reduce a grating lobe of a waveguide array antenna system. SOLUTION: Placing many slot antenna elements in a waveguide forms a transmission or reception waveguide array antenna system. Radio wave reflectors 103 two of which have each antenna element 102 inbetween in an arrangement direction of the antenna elements 102 are placed on a side face 104 of the waveguide 101.

Title: Method for recording image
Inventor: SAWANO MITSURU
IPC: B41J2/36
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent color shift even when a dither pattern is used. SOLUTION: There is disclosed a method for recording an image wherein a unit lattice Dp is formed by a plurality of dots arranged in a main scanning direction which is an arrangement direction of the recording elements and arranged in a sub-scanning direction perpendicular to the main scanning direction. A sum of recorded areas is varied by presence or absence of the recording of dot or variation of the size of the dot so that gradation of the unit lattice Dp is represented. A multi-color image is recorded by combining the unit lattice Dp of each of colors, i.e., yellow, magenta, cyan and black. A ratio of the combination of the sizes of the unit lattices Dp in the subscanning direction among colors is made to be a non-integer number.  It is preferable to make the combination of the ratios of the sizes of the unit lattices Dp in the subscanning direction to be '10:12:15:20' in no particular order.

Filed: 1987-06-12
Abstract: PURPOSE:To increase a read speed of a business form by reading only a part whose read is necessary, of the business form by limiting a range of character field width of the business form. CONSTITUTION:In a business form format memory 5, a data in which a character field position to be read, of a business form has been designated, based on a prescribed side edge of the business form as a reference is stored. A read control part 4 reads out an image data from an image memory 3, and segments a character field, based on the business form format memory 5. In that case,a side edge of the image data which has been read in the image memory 3 is different from a reference edge of the business form, therefore, the read control part 4 uses the side edge of the image data as the reference edge with respect to a character field position and corrects a position dimension of a business form format. Subsequently, based on its data, the character field is segmented from a business form image data of the image memory 3. In such a way, the character reader does not read a part which is not required for segmenting the character field.
