Title: Color picture processing unit
Inventor: INOUE YORIYUKI
IPC: G06T9/00
Filed: 1993-06-16
Abstract: PURPOSE:To provide the color picture processing unit by which color reproduction with fidelity to an original picture is attained at image forming and which is communicated with a black/white facsimile equipment represented by a G3 equipment in compliance with the CCITT recommendations most widely spread at present at picture communication. CONSTITUTION:A signal from a picture input section 8 is converted into L*a*b* or the like of a CIE color representation system by a standardizing signal section 9. In the case of a color picture output, a parameter for a full color hard copy is outputted to a color picture output device by a 1st density conversion correction section 10 comprising a UCR/black generating section 11, a color correction masking section 12 and an output gradation correction section 13 or the like. In the case of facsimile communication, only a lightness signal L* converted by the standardizing signal section 9 is inputted to a 2nd density conversion correction section 14, and its output is compressed by a binarization section 15.

Title: Rare earth-iron-nitrogen alloy powder and its production
Inventor: TOMIMOTO TAKAHIRO
IPC: H01F1/06
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To stably increase the coercive force of the alloy powder and to reduce the dispersion thereof by executing drying in such a manner that the powder is heated to a specifid range in an evacuated state. SOLUTION: As the raw material, rare eath oxides, iron and/or iron oxide is used, their mixture is reduced and diffused with Ca to form into an alloy block, and successively nitriding treatment is executed. Since the oxide of Ca, Ca nitride or the like used for the reaction is contained in the alloy block, these compounds are collapsed by the immersion into water, and removed by washing with water. The water-washed, alloy powder particle suspended matter is subjected to solid-liq. separation and drying. The drying is executed in such a manner that the material is heated at 100 to 240 deg.C in reduced pressure. In the case the drying is executed in the evacuated state, concretely at about 0.02 Torr vacuum, the residual water content reaches <=660 ppm. In this way, alloy powder having >=13.8 k Oe coercive force can be obtd after the drying.  Moreover, an average grain size of 1 to 5 μm is preferable for the powder, by which its coercive force can be increased.

Title: Electrophotographic sensitive body
Inventor: OOTAKE TSUTOMU
IPC: G03G5/04
Filed: 1983-08-09
Abstract: PURPOSE:To prevent deterioration of characteristics and damage by forming an amorphous silicon layer between silicon carbide layers each having different conduction type. CONSTITUTION:An SiC layer 202 contg. 5-50ppm B, an alpha-SiC layer 203 contg. 1-100ppm B, and an SiC layer 204 cong. 5-50ppm P are formed in this order on a metallic substrate 201. When the surface of the layer 204 is positively charged, positive holes produced by light pass through the layers 203 and 202 and arrive at the substrate 201. Since the layer 202 contains B and exhibits positive type conduction, the positive holes easily pass due to small probability of recombination. On the other hand, electrons produced by light also pass very easily through the layer 204 and reach the surface to erase the electrostatic charge applied before. Therefore, at the areas exposed to the light, current flows from the surface of the layer 204 toward the substrate 201 and the applied charge is erased.

Title: Washing machine with water-storing receptacle
Inventor: NUKAGA SUNAO
IPC: D06F33/02
Filed: 1989-06-08
Abstract: PURPOSE:To pertinently wash all the time by a method wherein washing-agent solution is reused only in the case where both the concentration of the washing-agent and transparency are respectively equal to each of reference values or above. CONSTITUTION:In a concentration-detecting device 41, the specific resistance of supply water is measured by electrodes 50, 51 of a bridge 49, and the specific resistance of washing-agent solution, by the others of electrodes 52, 53. A potential difference S between terminals A, B is inputted to a microcomputer 24. By the microcomputer 24, the S is converted from analog to digital, which is compared with a reference value ST stored in a ROM 27 and, when the S is equal to or above the ST it is decided that concentration is satisfactory. In a transparency-detecting device 42, a light-emitting element and a light-receiving element are located facing to each other. The more muddy the washing-agent solution is, the lower the receiving amount of the light-receiving element is, and voltage D becoming low in proportion to the receiving amount of the light is inputted to the microcomputer 24. By the microcomputer 24, the D is converted from analog to digital, which is compared with a reference value DT stored in the ROM 27 and, when the D is equal to or above the DT, it is decided that the washing-agent solution does not become muddy. After a cleaning stage is ended, when the S is equal to the ST or above and the D is equal to or above the DT, it means that the concentration is reasonable and the transparency is satisfactory. In this case, after the washing-agent solution is transferred, a washing stage and a centrifugally draining stage are, in order, carried out.

The sealing mask is provided with an outflow port 4 for removing bubbles and the excessive soln. mixture. The soln. mixture composed of a UV curing type oligomer, monomer and liquid crystal is then packed into the joining frame body. Another substrate coated uniformly with a spacer material is stuck thereto and the substrates are pressed down to a prescribed cell thickness. The substrates are heated on a hot plate at this time, by which unequal flow is removed. Finally, the sealing material is cured by a belt exposing machine and the UV curing type component in the soln. mixture is simultaneously cured and is phase separated from the liquid crystal to form the PDLC. Namely, the large-area liquid crystal display element is produced by the simple process without depending on the viscosity of the mixture composed of the matrix high-polymer forming material and the liquid crystal material.
