Title: Method of density irregularity correction in image
Inventor: YUGAWA NORIAKI
IPC: G06T1/00
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for easily performing a detect processing without being influenced by overall density irregularity of a picture by setting in a variable density picture of a detected body a partial picture of arbitrary form and size all around of which a proximity picture element is arranged, obtaining a difference between central density data and density data of a picture element under consideration and eliminating a density irregularity existing in the variable density image. SOLUTION: Regarding a picture element under consideration 11, a peripheral picture element density sort circuit places density data of four peripheral picture elements 12, 13, 14 and 15 in descending order. Then, in a background density calculation circuit, density data (d) and (a) except the biggest density data (c) and the smallest density data (d) out of the density data arranged in descending order of density data are selected, the average value of them is obtained and is through to be a background density [back] as central density data. A correction density calculation circuit compares the picture element under consideration 11 with the background density and performs density correction. When the density correction with a partial image 10 is finished, a setting process of the partial image is started.

IPC: H04N5/335
Filed: 1990-11-06
Abstract: PURPOSE:To reduce the two-line out-of-focus of an object between two fields by eliminating a time difference between two electric charge storage periods. CONSTITUTION:In the waveforms of a vertical blanking signal V-BLK and a driving pulse phiV of a CCD for a vertical transfer, at a period t1, an unnecessary electric charge is read out from a picture element part to the vertical transfer CCD, and at a period t2, the unnecessary electric charge in the vertical transfer CCD is inversely transferred at high speed, then swept out to a drain part 6. Next, the electric charge stored in a Ts1 period is read out at a period t3 from the picture element part to the vertical transfer CCD, moreover, transferred at high speed at a period t4 from the vertical transfer CCD to a storage part. And the electric charge stored in a period Ts2 is read out at a period t5 from the picture element part to the vertical transfer CCD. That is, the time difference between the storage periods Ts2 and Ts2 is eliminated. Thus, the influence of the object which moves at the time between the two fields is minimized, ant the two-line out-of-focus is not generated on the reproduced picture.

Abstract: PURPOSE:To provide a method for coating the blade surface of a tool with a high wear resistance material to uniform thickness with high precision. CONSTITUTION:While a high wear resistance material electrode 3 is moved relatively along the surface of the tool 1 to be coated so that no arc discharge is caused, the tip of the high wear resistance material electrode 3 is put close to the tool surface, pulse discharge is caused by applying voltage pulses between the high wear resistance electrode and tool surface, and a fine dissolved part atop the high wear resistance material electrode is repeatedly deposited on the tool surface by dislocation to form a coating layer 3 of the high wear resistance material on the tool surface. At this time, the coating process is performed while discharge energy per unit area which is generated by the discharge on the tool surface is held constant per tool unit area by moving the high wear resistance material electrode 3 or tool 1 along an NC driving track according to the tool shape. The thickness of the coating layer becomes uniform and the tool with superior machining performance is manufactured.

Title: Center printer output device for on-line terminal slip
Inventor: YAMANE TOSHIAKI
IPC: G06F3/12
Filed: 1990-11-05
Abstract: PURPOSE:To eliminate the need for forming programs to be outputted from a center printer as much as the number of slips by converting the print image of a terminal slip with a general purpose program and outputting the converted image to the center printer. CONSTITUTION:A 1st input means 11 inputs a parameter specifying that a terminal printer is a serial printer (MPP) or a page printer (NIP). An input file determining means 12 determines that a print image file is for the MPP or the NIP and a 2nd input means 13 inputs an on-line terminal slip printing image file 10 for outputting a slip to the terminal printer determined by the means 12. A conversion means 14 converts the control code of the input file into a center printer control code based upon an MPP character pitch conversion code table, an NIP character size conversion table and a printing position code table. Consequently, it may be unnecessary to form programs to be outputted from the center printer as much as the number of terminal slips.

Abstract: PURPOSE:To detect the variations in the wavelength and intensity of a light by providing a multiple quantum well structure having an absorption end coincident with the wavelength of a light to be detected at the light incident side to a light absorption layer in a semiconductor laminated structure. CONSTITUTION:A crystalline layer 12, a light absorption layer 13, a crystalline layer 14 and 15 are piled on a semiconductor substrate 11. A multiple quantum well structure 16 is provided at the center of the layer 15, and a crystalline layer 17 is piled on the upper surface of the structure 16. In this photodiode, when a light having predetermined energy is radiated, an electromotive force is generated in the laminated structure. Accordingly, when a reverse bias voltage is applied through a P-type electrode 23 and an N-type electrode 24, a photocurrent flows reversely. In this case, when the applied voltage is varied, e.g., when a voltage is applied or not applied to the structure 16 through the electrodes 20, 23, the structure 16 may be used as a filter having a different function. Thus, variation in the wavelength can be detected, and the variation in the intensity of the light can be also detected.

Filed: 1988-11-29
Abstract: PURPOSE:To obtain a paper levitation preventing mechanism generating uniform paper pressing force corresponding to a thickness change of paper by directly mounting a paper press plate to a printing head and forming the paper press plate itself into a leaf spring shape. CONSTITUTION:A paper press plate 2 is fixed to a thermal head 1 and formed into a leaf spring shape as a whole and the leading end part can be bent in a direction 7. In a printing state, the paper press plate 2 is pressed to paper 3 along with a thermal head 1 and the upper part of the paper 3 is warped toward a platen 4. When the paper 3 is thick at this time, the paper press plate is bent in the direction 7 and, therefore, the paper pressing force corresponding to a paper thickness is generated. By forming the paper press plate itself as a leaf spring, stable paper pressing effect can be obtained even with respect to a thickness change of paper.
