Title: Method for eliminating blocking phenomenon using sequential projection, and post-processor for the same
Inventor: CHANG JOON-HO
IPC: H04N19/625
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To eliminate blocking artifacts blocking phenomenon through the use of projections onto the overcomplete basis(POCB) by producing a video signal which is post-processed through POCB to non-orthogonal basis even though a post-processed video signal is generated which approximates a decoded video signal to an original video signal by using non-orthogonal basis. SOLUTION: An area dividing unit 210 of a post-processor 200 superimposes a decoding video signal that is applied from a decoder 100 on a small block and performs area division. A POCB processor 220 processes divided 16×16 blocks for POCB based on sequential projection algorithms of 1st to 3rd stages to produce projection coefficients. A bilinear superposing device 320 eliminates blocking phenomenon for POCB. That is, it receives a decoded video signal of a video signal which underwent block based coding and produces a post- processed video signal which is an approximation of the original video signal obtained by using non-orthogonal basis. However, it produces a video signal which is post-processed through POCB to the non-orthogonal basis.

IPC: C09B67/20
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain the subject pigment having high coloring force and exhibiting vivid hue without impairing productivity, economical efficiency, quality stability or the like by subjecting crude β type copper phthalocyanine to wet grinding by a specific method and then, subjecting the resultant powder to specific treatment.

Title: Cup shaped grinding stone
Inventor: KOBAYASHI MASAJI
IPC: B24D7/02
Filed: 1984-11-05
Abstract: PURPOSE:To prevent the central part of a workpiece from generation of minute projections for the purpose of flattening the whole surface of a work surface and also minimize the imbalance of rotation by providing the circular body of a grinding stone eccentrically to the rotary axis of the grinding stone. CONSTITUTION:The circular body 11 of a grinding stone polishes a workpiece 12 moving at a high speed in the peripheral direction and making a round movement between the right side 101' and the left side 101 centering the rotary axis 21 of the workpiece 12 being caused by the eccentricity of the circular body 11 of the grinding stone to the rotary axis 22 of the grinding stone. As a result, the workface of the workpiece 12 is flattened without generation of projection. In this grinding process, since the circular body 11 of the grinding stone is eccentrically attached to the base metal 18 having a concentricity with a non-eccentric rotary axis allowing only the circular body 11 of the grinding stone to perform eccentric rotation, the imbalance of rotation is extremely decreased and as a result, the balance can be readily obtained by balancing operation.

Filed: 1988-09-16
Abstract: PURPOSE:To improve the living comfortableness and thermal efficiency by passing a thermal medium at the space under the floor through pipes which are buried in a layer of concrete overlying a heat-insulating grounded layer. CONSTITUTION:A grounded heating unit 10, designed to heat the space 3 under the floor and also shut off the entry of moisture from the ground comprises a heat-insulating grounded layer 11, a layer of concrete 12, and thermal medium- conveying pipes 15. When a thermal medium, such as hot water, is passed through the thermal medium-conveying pipes 15 to effect heating from the ground, the heat-insulating grounded layer 11 stops the heat from escaping to the ground. The layer of concrete 12 functions as a heat storage material and also as a material for dispersing the heat from the thermal medium- conveying pipes 15; by burying the pipes 15 in the concrete 12, if it should happen that water stands and freezes in the pipes 15, it is prevented for the pipes 15 to burst. The thermal medium-conveying pipes 15 are pipes of copper, a plastic material, or the like; heating by the grounded heating unit can be effected by passing a thermal medium, such as an antifreezing liquid or gas, therethrough.

Title: Core material for bending plastic tube and bending method using same material
Inventor: YAMADA YONEKAZU
IPC: B29C53/08
Filed: 1991-09-12
Abstract: PURPOSE:To facilitate pressing in a mold when a plastic tube is molded, to prevent the flatness of the tube and to draw a core material easily from the tube by constituting a core material body by laminating flexible sheet metals in an approximately circular cross section while forming a cavity section an installing a tube, which is composed of an elastic body and into which a fluid can be injected, in the cavity section. CONSTITUTION:In the bending method of a plastic tube 2 using a core material 1, the pressure of a tube 15 mounted to the cavity section 111 of a core material body 11 pushes wide the sheet metals 1A-1L of the body 11 in the direction of laminating and works in the direction of adhesion to the internal surface of the tube 2 when the tube 15 is expanded and contact- bonded with the wall surface of the cavity section 111. Consequently, the tube 2 can be bent and molder under the state in which the body 11 and the tube 2 are fast stuck sufficiently. As a result, the cross section of the body 11 can be held in a true circle in an approximately original shape, and the generation of creases and white color on the surface of the tube 2 can also be prevented. Since the tube 15 is shrunk and the core material 1 is drawn out of the bent and molded tube 2, frictional resistance between the core material 1 and the tube 2 is lowered only by a section, in which the bending reaction of the body 11 is reduced, thus allowing drawing by force smaller than conventional devices.
