Title: Erroneously corrected line retrieving device
Inventor: IIO MAKI
IPC: G06F12/00
Filed: 1994-06-24
Abstract: PURPOSE:To exactly find out an erroneously corrected line with the possibility of existence in a source program under alteration for function addition or the like in a short time. CONSTITUTION:When checking whether the source program under alteration at present is erroneously corrected or not, a programmer inputs an erroneously corrected line retrieving instruction from an input device 2. In response to this instruction, an input means 11 inputs the source program under alteration and a source program before alteration from a source file and stores them in a memory 12. Concerning the altered line in the source program under alteration, an identifier showing its kind is set by the programmer. Concerning the respective lines, to which the identifier is not set, in the source program under alteration, a comparing means 13 compares contents with the correspondent lines in the source program before alteration decided based on the kind of alteration shown by the identifier and outputs information showing the comparatively non-coincident lines.

Title: Method of growing crystal
Inventor: IZAWA NOBUYUKI
IPC: C30B15/20
Filed: 1985-07-27
Abstract: PURPOSE:To control oxygen concentration and to obtain crystal having desired purity in good reproducibility, by pulling up silicon crystal while impressing a magnetic field in the horizontal direction to silicon melt stored in a quartz container. CONSTITUTION:The quartz container 2 having the silicon melt 3 is heated by the electric heater 5 of the heating means 4, and a magnetic field having about 400 gauss is impressed to the melt in the horizontal direction of the melt by the DC magnetic field generating means 7. Then, the silicon crystal 8 is brought into contact with the melt 3, and the crystal 8 is pulled up at a given speed while rotating the container 2 or the crystal 8 relatively, to grow the silicon crystal 10.

Title: Aqueous ink for ball-point pen
Inventor: TAGA HIDEJI
IPC: C09D11/00
Filed: 1979-12-21
Abstract: PURPOSE: To reduce tip abrasion due to ball rotation, to supply ink smoothly and uniformly and thereby to improve writability, by adding a metal naphthenate to an aqueous ink for ball-point pens containing a dye, water, etc.  
     CONSTITUTION: The ink of the purpose is prepared by adding about 0.01W5wt% salt of a naphthene ring-containing saturated carboxylic acid with a metal such as Co, Mn, Zn, Al, Cu, Na, K or Li to an ink for ball-point pens containing a dye, water, etc. The reason why such a metal naphthenate can give excellent lubricity is considered to be as follows. The metals of a metal naphthenate adhere firmly to a ball and the metal part of a ball holder, and the naphthene rings and the aliphatic hydrocarbon chains form a film at the interface between the ball and the holder. This film prevents direct contact between metals or between metal and plastic.

Abstract: PURPOSE:To prevent the over-erasion of data despite the presence of an easy-to- erase cell by applying the high voltage to a storage in a data erasion mode via a high resistance connected to a source line of a block. CONSTITUTION:The drain potential, the control gate potential, and the source potential of an ETO type cell are applied through a bit line 15, a word line 12, and a block source line 14 respectively. When the data are written, the high voltage is applied to a selected line 15 together with the high voltage VPP applied to the line 12 and an internal power node SW set at an earth potential respectively. Meanwhile the data are erased with the earth potential VSS applied to all lines 12, with a transistor 16 turned off for selection of columns, and with the voltage VPP applied to the node SW respectively. A high resistance 19 is connected to each line 14 and the high voltage is applied to the line 14 of a selected block via the resistance 19.

Title: Fused siliceous roll for heat treatment furnace
Inventor: SUGIE MASUO
IPC: C21D1/00
Filed: 1981-10-20
Abstract: PURPOSE:To provide a titled fused siliceous roll on which the deposits from strips are hard to stick and from which the stuck deposits are removed before accumulating to cause build-ups by specifying the surface roughness of the fused siliceous roll which is bound by sintering. CONSTITUTION:After raw materials consisting essentially of fused silica are molded by casting and are bound by sintering, the surface thereof is machined and ground whereby a fused siliceous roll for heat treatment furnaces is manufactured. Here it is an essential requirement to specify the surface roughness of the outside surface of said roll at 20-140mum Rg(L=15ww). If the surface roughness is specified as mentioned above, a strip contacts only with the head parts in the projecting parts 1 of the ruggedness on the roll surface and deposits 2 stick thereon but not in the recesses 3. Since the deposits 2 have small affinity to the fused silica and have low sticking resistance, the deposits on accumulation to a certain extent are easily dislodged by friction with the succeeding strip and are thereby removed without growing to large build-ups.
