IPC: H02K5/04
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain a motor with a high reliability by a method wherein a 1st board and a 2nd board are housed in a covering case to be isolated from an outside atmosphere. SOLUTION: A board for driving a motor is divided into a 1st board 15 and a 2nd board 20. The 1st board 15 detects the rotation position of a rotor and forms the position information to generate a current application switching timing signal which is supplied to a driving control circuit. The 2nd board 20 drives and controls a rotor and applies a driving control voltage to the rotor by receiving a power supply. The respective boards are housed in a covering case 17 which is attached to a frame. The board 15 is fixed to the covering case 17 by a fixing screw 16 with a very small distance between a driving magnet 14 and itself. The board 20 is fixed to the inside bottom of the covering case 17 by a bolt 18 and a fixing nut 19 and tightened with the covering case 17 through a tie-bar 21.

Title: Spike pin for spike tire
Inventor: YAMAGUCHI YOICHI
IPC: B60C11/16
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To improve the performance of a tire with its spike pin on ice by forming a hardened porous carbon material having the specific Vickers hardness in which chipped vegetable raw materials are impregnated in a thermosetting resin and heat treated at high temperature into carbonize to obtain the spike pins for a spike tire. SOLUTION: A hardened porous carbon material in which chipped vegetable raw materials such as rice bran and chipped wooden materials are impregnated in a thermosetting resin, and heat treated at high temperature into carbon, is formed to obtain a spike pin of 30-1500 in Vickers hardness. This spike pin is lower in hardness than an asphalt road surface of 1000-1500 in Vickers hardness, but higher in hardness than ice of 30 or under in Vickers hardness so that brake performance on an icy road surface can be improved. Though the braking performance on ice is equivalent to that of a conventional metal spike pin formed of steel or iron, the durability is equivalent to and larger than that of the metal spike pin due to the excellent wear resistance of the hardened porous carbon material.

In the formula, Lm is a rare earth element containing 70-100 wt.% La, M is one or more element of Co, Al, Fe, and Zr; 3.30<=x<=4.50, 0.01<=y<=0.30, 0.20<=z<=1.70, 4.90<=x+y+z<=5.50. Saturation magnetization by ferromagnetic component on the surface after dipping at 60 deg.C, for 48 hours in 8N potassium hydroxide aqueous solution is 3.0-9.0 emu/m2. Thus, a hydrogen storage amount increases to increase capacity per unit area of a negative electrode.

Title: Machine translation system
Inventor: NII MASAHARU
IPC: G06F17/28
Filed: 1994-03-15
Abstract: PURPOSE:To output a natural translation result by translating a character string (sentence) while taking positions of parts (phrases or the like) in the character string. CONSTITUTION:An input means 5 inputs a first language character string and a second language character string obtained by translating the first language character string to the second language. A parts link information generating means 4 generates parts link information indicating the correspondence between first language parts constituting the first language character string and second language parts constituting the second language character string. A register means 3 registers this parts link information in an original-translation data base 2 while making this information correspond to first and second language character strings. A translating means 1 retrieves the first language character string similar to an original character string as the translation object and discriminates whether an equivalent for first language parts in this first language character string exists in the original character string or not. The translating means 1 extracts second language parts which are an original-translation for first language parts and successively determines the original-translation for first language parts constituting the original character string, thus translating the original character string.

Abstract: PURPOSE:To certainly prevent the generation of red water containing ferric oxide by separating and removing impurities whose particle size exceeds a specific value contained in water by using a precise filter membrane and subsequently separating and removing oxygen and air contained in water by using a degassing membrane. CONSTITUTION:The raw water in a water tank 2 is sent to a precise filter device 7 using a porous membrane as a filter material by a water supply pump 6 and, after impurites whose particle size exceeds 0.01-10mum contained in the raw water are separated and removed in this device, the filtered raw water is sent to a degassing device 8 using, for example, hollow yarns of a gas separation membrane and air or oxygen dissolved in the filtered water is removed under reduced pressure due to a vacuum pump 9 in the degassing device 8. Oxygen is usually dissolved in tap water in an amt. of about 8ppm and an iron pipe is corroded by this oxygen to generate red water. Therefore, degassed water with dissolved oxygen content of 0.5ppm or less is obtained in the degassing device 8 and red rust is reduced to be changed to black rust by the degassed water to prevent the advance of the corrosion of the iron pipe.
