Title: Image-processing unit
Inventor: OOKUBO NATSUMI
IPC: H04N1/46
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide the image-processing unit in which an image is subject to emphasized contrast with a saturation adaptive to the image. SOLUTION: An image data division section 102 classifies image data, forming an input image into a plurality of groups, depending on the luminance of each picture element. A histogram measurement section 103 calculates a saturation histogram, representing the distribution of saturation of the image data for each group. A histogram modification condition setting section 104, a histogram modification section 107 and a level conversion condition setting section 108 generate a lookup table (LUT), to correct saturation of the image data, so that the saturation with high frequency and the saturation with low frequency in the saturation histogram, keep a current frequency, and the frequency of other saturation is close to flatness. A level conversion section 109 uses the LUT, to correct the saturation of the image data.

Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method; for reducing the occurrence of a casting fin in a coolant passage at the time of casting, and realizing the improvement of productivity; in the cylinder head of a liquid cooling internal combustion engine. SOLUTION: In this method, the load of a casting fin, for preventing or hindering the flow of a coolant via a cylinder head, is reduced. The head can be cast without an internal liquid coolant passage for connecting first and second cooling cavities 80 and 90 with each other. An opening 84 is machined via the outer surface of the head for demarcating the passage crossing between both the cooling cavities so as to communicate cooling liquid between both the cooling cavities. The opening, formed by machining via the outer surface of the head, is closed by a plug 89. The throat area of the passage is selected so as to control the coolant replacement between both the cooling cavities. Moreover, an additional passage is machined to the respective heads to replace an additional coolant, or discharge air from the cooling cavities.

IPC: C08J5/18
Filed: 1994-07-21
Abstract: PURPOSE:To prevent the generation of a stripe defect in a casting direction caused by the adhesion of the gelled substance of a dope to the leading end of a die by setting the temp. of hot air immediately after casting to a predetermined range and setting the moving speed of a metal support to a desired value. CONSTITUTION:A dope with soln. viscosity of 5-200 poise is cast on a metal support 6 from a die 4 composed of a lip 11 having a smooth edge 10 at its tip. It is desirable to set the temp. of hot air immediately after casting to 5-40 deg.C. When the temp. of hot air is set to 5 deg.C or lower, a waterdrop is bonded to the surface of a dope film and cloudiness is easy to generate on the surface of the dope film. When the temp. of hot air is set to 40 deg.C or higher, the evaporation speed of a solvent becomes high and the adhesion of the gelled matter of the dope film to the leading end of the die 4 becomes impossible to suppress. The moving speed of the metal support 6 is set to 0.5-10m/min.

Title: Organic electroluminescent material and electroluminescent element using same
Inventor: HASEGAWA NORIO
IPC: H05B33/14
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain an organic electroluminescent material capable of uniform and high-luminance electroluminescence, which material has a specified structure. SOLUTION: The electroluminescent material has a structure represented by the formula. This material is obtained by mixing a solution containing a material composed of bonding groups X and substituents Y with a solution containing a dissolved metal Me, agitating the combined solution under heating to progress a complexing reaction, and removing the solvent from the reaction mixture by distillation. In the material, molecules arranged around the metals Me are bonded through coordination, so that it becomes difficultly bondable to the surrounding luminescent materials, which results in its difficult crystallizability and its nearly flat shape. Therefore, when a luminescent element is formed from particles of the luminescent material, the particles are laminated without leaving any clearance, can be arranged densely, and realize high luminance.  Further, the element can uniformly fluoresce since it has no clearance. Furthermore, the luminescent material has many double bonds, so that it tends to emit light having a long wavelength and is capable of emitting nearly red light.

IPC: H05K1/02
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress the breaking of a substrate in a manufacturing process by disposing unit substrates so that the slits may be shifted with the ones adjacent in the longitudinal direction of the unit substrates. SOLUTION: An aggreagative substrate 1 is made by arranging a plurality of rectangular unit substrates 2 which will become chip type resistors. Each of the unit substrates 2 has a rectangular shape extended in the longitudinal direction. The aggragative substrate 1 is partitioned by BB(bar break) slits 3 formed in the vertical direction and CB(chip break) slits 4 formed in the horizontal direction. The CB slits 4 are so formed as to be shifted with the ones adjacent in the longitudinal direction by shifting the unit substrates 2 from the ones adjacent in the longitudinal direction. Due to this structure, the bending force of the aggregative substrate 1 in the vertical direction can be increased and therefore the cracking of the aggregative substrate 1 can be suppressed in a manufacturing process.
