Title: Variable-length encoding method, variable-length decoding method and variable-length code recording medium
Inventor: SUGIYAMA KENJI
IPC: H04N19/51
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To encode a discrete signal having high occurrence frequency of prescribed value, especially such as zero by using a continuous number (run length) of the prescribed value in a variable-length encoding method according to highly efficient encoding that changes image information into a digital signal with less code quantity in order to transmit, store and display an image efficiently. SOLUTION: This encoding method collects discrete signals having high occurrence frequency of prescribed value in a prescribed partition to perform one-dimensional array and performs variable-length encoding that forms a code string with a variable-length code showing the continuous number of the prescribed value and a variable-length code showing a level that is not the prescribed value. In such a case, when an initial value of the prescribed partition is the prescribed value, encoding starts from variable-length codes (5 and 6) showing the continuous numbers of the prescribed value, on the other hand, when the initial value of the prescribed partition is not the prescribed value, encoding starts from a variable-length code (9) showing a level that is not the prescribed value.  An identification code (3) that identifies whether an initial code of the code string is a variable-length code showing the continuous number of the prescribed value or a variable-length code showing the level is added in every code string.

IPC: B23K26/18
Filed: 1981-04-23
Abstract: PURPOSE:To improve the accuracy and yield of working and to prevent chipping, cracking, etc. of a work by providing protecting bodies of a material which is difficult to be worked by laser in such a way as to abut on both side surfaces at the working start point and working end point of the work. CONSTITUTION:A work 13 is placed and fixed on a positioning table 12 which moves in arrow 11 directions, and the laser 14 from a laser oscillator 18 is condensed through a condenser lens 15 to the desired position of the work 13. Protecting bodies 21, 22 consisting of a material that is difficult to be worked by the laser 14 and or a material which is difficult to absorb the laser 14 are provided at the working start point 15 and working end point 17 of the work 13, and the positions 211, 221 of the bodies 21, 22 that contact the work 13 are inclined so as not to hamper the condensation of the laser 14. As a result, the laser 14 weakens at the point 16 and the working end point and therefore the heat capacity of the work 13 decreases and the accumulation of heat therein decreases; thus the chipping, crazing, cracking, etc. of the work 13 are obviated, and the accuracy and yield of working are improved.

Title: Manufacture of pipe
Inventor: SAKAGUCHI MASAYUKI
IPC: B29C65/34
Filed: 1990-03-12
Abstract: PURPOSE:To prevent unevenness of fusion welding by utilizing Curie temp. of magnetic alloy to heat a fusion welding part and holding the heating temp. constant. CONSTITUTION:Firstly a plate 10 made of thermoplastic resin is prepared in which magnetic alloy 12 having the prescribed Curie temp. is formed in at least one side end in the crosswise direction. The one side end of this plate 10 is overlapped on the other side end. When high-frequency current is imparted to this magnetic alloy 12, it is heated by skin effect and its temp. is raised. When the magnetic alloy reaches Curie temp., magnetic permeability of magnetic alloy 12 is suddenly made small and current does not hardly flow and the temp. of magnetic alloy is not raised higher than Curie temp. Furthermore when the temp. of magnetic alloy is lowered by heat dissipation, current starts to again flow in the magnetic alloy 12. Since such motion as this is repeated, the temp. of magnetic alloy 12 is substantially held at the prescribed Curie temp. Therefore the interval of the overlapped end parts is welded by fusion at the prescribed Curie temp. or the vicinity thereof.

Title: Ice-skating rink
Inventor: NOMURA KIYOUSUKE
IPC: A63C19/10
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the variety of ordinary ice-skating by sloping the surface of ice of an ice-skating rink. SOLUTION: The outside of the curved section of an oval ice-skating rink is covered with a fixed shuttering 1, and a temporary shuttering 2 is installed in the inside thereof. And then water is poured and is frozen. And then the temporary shuttering 2 is removed, and ice is removed while decreasing the amount of ice to be removed from the inside toward the outside as shown by a shaded section, a bank 4 whose inside is sloped downward is formed in the curved section. As a quick cooling of a large amount of water all at once may cause cracking, making the ice fragile, it is desirable to obtain a prescribed thickness by freezing the water bit by bit and adding to the thickness one after another. As the method of scraping ice off is wasteful, the inside is divided into multiple sections, each of which is sloped in a manner of making the slopes continuous.  The formation of slopes improves the variety of ice-skating and leads to an introduction of a new ice-skating method.

Title: Tape carrier package
IPC: G02F1/1345
Filed: 1992-03-18
Abstract: PURPOSE:To surely connect connection terminals to the terminals of a device to be connected and to improve the reliability of a connection terminal part by coating wide connection terminals formed on a base film with solder resist and forming through holes on a base film terminal part. CONSTITUTION:The connection terminals TTM 7 formed on the base film BFI are widely constituted and coated with solder resist SRS and the through holes THH connected to the terminals TTM 7 are formed on the base film terminal part TMP. Even when the connection terminal part of a tape carrier package TCP is thermally expanded by heating it in order to connect the terminals TTM 7 to the terminals of the device to be connected and a positional shear between the center line of the terminals TTM 7 and that of drain terminals DTM is generated, electric erosion is not generated even when space width between connection terminals is short because the real line width of the terminals TTM 7 is wide and the TTM part is coated with the resist SRS. Since the adjacent length between the holes THH is short, the generation of electric erosion can also be prevented in the holes THH.

Abstract: PURPOSE:To perform blast humidity controlling of a blast furnace easily and accurately by adding the maximum value moisture content of moisture content differences to the blast furnace moisture content when the blast moisture content of the blast furnace is lower than the atmospheric moisture content then removing the maximum value moisture content from the total blast. CONSTITUTION:The forecast value of the maximum of the difference between the atmospheric moisture content C and required blast moisture content is estimated from the past records and the furnace conditions of that time. If the estimated forecast value is, for example, 10g/Nm<3>, humidifying D is carried out successively with a humidifier 3 where the difference between both is <=10g/Nm<3>, whereby the difference between both is regulated constantly to 10g/Nm<3>.
