Title: Image processing unit
Inventor: SHINOHARA KOICHIRO
IPC: G06T1/20
Filed: 1995-03-15
Abstract: PURPOSE: To prevent discontinuous gradation from being caused while keeping a gradation characteristic with fidelity by superimposing prescribed noise to input image data in a density area decided to be an area having a high gamma. CONSTITUTION: A density detection means 5 measures a gradation characteristic path or the like generated by the output of a reference pattern signal generating section 13. The gradation characteristics of an image output device 17 is calculated based on a measured reference pattern density and a calculation means 15 calculates a conversion table for gradation correction and stored in an LUT in a high gamma area decision means 12. The high gamma area decision means 12 obtains a gradient of the gradation characteristic as a function of an input image signal. The density area of the input signal whose density gradient is higher than a set gradient from an input image signal source 14 is decided to be a high gamma area. When the image signal in the high gamma area is received, a noise superimposing means 11 superimposes prescribed noise to input image data, and the generation of discontinuity in a gradation change is suppressed even when density is changed continuously on a print image.

Title: Printer control circuit
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J3/00
Filed: 1988-03-10
Abstract: PURPOSE:To substantially eliminate variation in a distance between centroids of printed-out pixels and to obtain a printed image by splitting one pixel unit at least to a sheet feeding direction, and altering the data of a gradation counter and pixel data between former half and latter half of split pixel unit. CONSTITUTION:Assume that the gradation of pixel data has 10, 31-10=21 is obtained a plurality of 1 or 5 bits... decimal notation in the former half, and compared with data 3a of a gradation counter 3. A comparator 5 discharge a print signal until the data 3a increases larger than 21 of the pixel data. It does not output a signal from 21 to 31. Since this is reverse, when it is inverted through an EXNR 15, the former half of 31-21=10 is printed out. Since the latter half becomes MSG=1 of the counter 3, the EXNR 13 discharges pixel data of true number. The comparator 5 outputs a print signal up to 10 while the data 3a is large. Thus, a printed pixel space is divided to 64, and solidly coated proportionally to the original pixel. Further, the centroid of the printed pixel substantially coincides with the center of the pixel space.

Title: Transmitter for color television signal multiplexed with additional signal
Inventor: KAWAI KIYOYUKI
IPC: H04N11/20
Filed: 1988-03-10
Abstract: PURPOSE:To transmit additional signals regardless of moving or still pictures by deleting the high band component of the luminance signal of a NTSC signal for addition of a color TV signal for additional information and limiting the band of a spectrum increasing component in a moving picture state. CONSTITUTION:The oblique high band component of the luminance signal of an existing NTSC signal is deleted and orthogonal amplitude modulation and then the multiplexing of frequency are applied to a color TV signal for additional information having its compressed band by means of said area where the oblique high-band component is deleted. Then the band limitation is applied to the component of said luminance signal with which the spectrum is expanded to the area where the oblique high band component produced in a moving picture state is deleted. Thus it is known that the band where the oblique high-band component of the luminance signal exists is not effectively utilized in terms of visual sense. Therefore, the color TV signal for additional information, even though superposed on said area, is not easily recognized in terms of the visual sense. Thus the existing NTSC signal is not disturbed. Furthermore, the additional signals can be transmitted even in a moving picture state because band limitation is applied to the component with which the spectrum is expanded to a deleted area in the moving picture state.

Abstract: PURPOSE:To transfer information to be transferred to the central processing device rapidly, by causing the terminal to oscillate the unit pulse of its own number to communicate with the central processing device when the terminal has informtion to be transfered to the central processing device. CONSTITUTION:The central processing unit transmits repeatedly unit pulses, whose number is equal to the number of terminal units, consisting of different pulse groups synchronously with the pulse train arranged in a prescribed order. In case that each terminal unit has information to be transmitted, the signal which can be discriminated from the unit pulse is output when the terminal unit itself transmits the unit pulse corresponding to the terminal unit, and th central processing unit transmits this signal and displays it on display circuit 8 and stops transmission of the pulse train together with the terminal unit during a prescribed time required for information receiving. Consequently, one cycle when respective termial units are called repeatedly is shortened considerably.

Abstract: PURPOSE:To insert a plurality of new pipes while the old pipes are collected completely, with damages to the peripheries avoided during new pipe insertion works, by filling the old pipes with a solidifying material from the group of pipes situated at lower stage sequentially to the group situated uppermore, and inserting new pipes during taking-out of the old ones solidified or to the space where the old ones have occupied after removing works. CONSTITUTION:When a solidifying material 12 is to be put fully in old pipes 4 which have been embedded underground 3 in stages group by group and which have decayed, the filling works shall be executed first with the group of old pipes 4G3 situated at the lowermost stage, then the group 4G2 at the middle stage, and finally the group 4G1 at the uppermost stage. If the solidifying material 12 put fully in all old pipes 4 by such a procedure has solidified after a certain period of curing, the pipes 4 are consolidated with the material 12 fast, and brittleness due to decay is improved. When these old pipes reinforced 4 are pushed out one after another in the laid position, splinters 4d likely to be produced from the old pipes 4 are free from risk of scattering underground 3 or in the space left because the old pipes 4 are consolidated with the solidifying material 12 fast. Therefore, new pipes 5 to be inserted as replacement during taking-out of the old ones 4 or to the space thus produced after taking-out are free from risk of having their peripheries damaged, and embedding works can be executed certainly and effectively.

Abstract: PURPOSE:To produce a boron vibration diaphragm, by forming a thin layer of a boride on a sintered zinc oxide substrate and forming a boron layer on the zinc oxide substrate by the chemical vapor-deposition method and removing by dissolving the zinc oxide. CONSTITUTION:Zinc oxide powder is formed into a disc of 20mm. diameter and 1.5mm. thickness under a pressure of 300kg/cm<2> by compression, and several discs produced in this manner are piled up and are put in an alumina board and are sintered in air at 1,100-1,400 deg.C for one hour. A sputtering device is used to stick films consisting of a titanium boride on the sintered zinc oxide substrate varying the film thickness to 0.01mum, 1mum, 2mum, and 4mum while heating it to 300-450 deg.C. These samples with film stuck are held at a temperature of 1,100 deg.C in a CVD reaction vessel with an infrared condensing lamp. Under this condition, a mixed  gas of one volium part boron trichloride and three volium parts hydrogen is controlled by a rotary pump and the operation of valves so that the pressure in the reaction vessel is 10 Torr. Thus, an amorphous boron layer with a thickness of about 80mum is formed. This substrate is cut by a laser, then zinc oxide is removed, thus obtaining a boron substrate.
