Patent JP-H09307747-A (JP)
Title: Resolution converter
Inventor: HORIE HITOSHI
IPC: H04N1/393
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To attain a high speed reduction processing by approximating an area discriminated to be a very small area among areas in a way of including the very small area to its adjacent area to extend a setting range of a reduction rate up to a range in excess of the reduction rate depending on a given picture element number or a line memory number. SOLUTION: A high-order 8-bit as a result of product sum result being an output of a projection filter 9 (assuming 256 gradation herein) is obtained from an adder 14. In the binarization processing, when the filter output is higher than a threshold level, a comparator 15 provides an output of '1' as a black level picture element and when not, the comparator 15 provides an output of '0' as a white level picture element. Contents of reference shift registers 10-12 are shifted left by an X-shift bit and a content of a counter is decremented simultaneously and when the count of the counter reaches 0, image data are given to low-order bytes of the reference shift registers. The processing above is repeated for several number of times, then one byte of reduced image data is generated and written in an image memory 13.  Then 0-bits are filled to reduced image data less than one byte at the end of each line and the resulting byte data are written in the memory 13. Thus, one line of the reduced image is generated.

Title: Graphic plotting device
Inventor: KIKUCHI TOSHIO
IPC: G06T1/00
Filed: 1990-05-10
Abstract: PURPOSE:To shorten time required for the reference of an attribute and to execute plotting at high speed by referring to a graphic processing table which is previously defined through the use of an index which is obtained by means of making the state of the attribute concerning a graphic into a bit pattern. CONSTITUTION:Respective bits of a register 4 are made to correspond to the attributes, and the value of the register 4 becomes an index value. On the other hand, the graphic processing table 2 is one to which a processing code equivalent to the index value correspond, and the processing code can be retrieved with the index value as a key. Graphic plotting processing modules 1-1 to 1-m learn the index value by referring to the register 4, and the graphic processing table is retrieved with the index value as the key so as to obtain the processing code concerned. Thus, a plotting processing is executed based on the processing code. Thus, a troublesome processing such as to execute plotting while all the attributes are referred to at every time is unnecessary to be executed.

Filed: 1995-05-17
Abstract: PURPOSE: To form a high-quality color image excellent in color reproduction and gradation reproduction with a simple constitution and reduced space by providing an image development suspending process for suspending a device temporarily after formation of each color. CONSTITUTION: An electrostatic latent image of the first color is formed on a uniformly charged photoreceptor drum 10 by a laser exposure device 2 and developed by a yellow developing unit 3. An image forming process is temporarily suspended in a state where a yellow toner image is held on the photoreceptor drum 10. Then, the yellow developing unit 3 is taken out and replaced with a magenta developing unit 3, to execute the image forming process of the second color. In this state, the image forming process is temporarily suspended again. The developing unit 3 is replaced with cyan and black developing units 3 in order, to repeat each image forming process. Thus, a toner image after superimposing development on the photoreceptor drum 10 is transferred to a paper sheet 9 by a transfer corotron 5.

Title: Magnetic tape driving controller
Inventor: NINOMIYA ICHIROU
IPC: H04N5/78
Filed: 1978-09-27
Abstract: PURPOSE: To obtain an efficient controller of simple constitution by limiting the speed of a magnetic tape within a tape speed range corresponding to the tape speed and tape length after rapidly feeding the tape and then by turning reels at low and constant speeds before the fixed time of a desired tape position.  
     CONSTITUTION: Motor 6 is rotated at a high speed to feed magnetic tape 4 rapidly. Then, motor 6 is turned at the high speed and stopped by turns to limit relation T 2 x' between tape speed 1/T and conversion time x' (One minute of the time of tape length "x" expressed by time is converted into 2 6  seconds.) corresponding to the tape length within a tape speed range. When tape position (x 1 ) leads desired tape position (x 0 ) by two seconds, for example, motor 6 is turned at a low speed to run magnetic tape 4 slowly and at a position one frame before desired tape position (x 0 ), a driving current is cut off to stop magnetic tape 4 at the fixed position. In this way, an efficient controller of simple constitution can be obtained.

Title: Method and device for cutting coil winding of transformer
Inventor: SHIOKAWA SEIJI
IPC: B23D25/14
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To suppress temperature rise in cutting and to prevent the mesh of a side surface from dulling and fine chips from being generated by moving a shear blade along the side surface of a core, cutting coil winding that is wound around the core by force cutting, and separating the core from the coil winding. SOLUTION: In a method for cutting coil winding, when hydraulic loading is supplied to a pressurization cylinder so that a shear blade 22 advances toward a work, the shear blade 22 travels along the side surface of the core, and the tip of the shear blade 22 strikes through coil winding 12, thus cutting the coil winding in the force cutting system. In the force cutting, when the force applied to the shear blade 22 from the pressurization cylinder is F, the cut coil winding goes upward with a component force of F1, and the core tries to escape downward with a component force of F2. However, the core is received by a core lifter 26 since the edge of the shear blade 22 is in tapered shape. Then, the reverse side of the edge located along the side surface of the core forms an escape part 22-1, thus preventing contact where the blade locally strikes through the side surface of the core.
