Title: Magnetic disk device
Inventor: SASAKI MASATERU
IPC: G11B21/08
Filed: 1978-12-22
Abstract: PURPOSE: To increase the positioning accuracy for the head by securing the simultaneous detection for the position signals which give the identification to both the odd- and even-order tracks along with increment of the servo head core width and then extracting the control signal featuring the high S/N ratio.  
     CONSTITUTION: The simultaneous reading is given to position signals P 1  and P 2  which give the identification to the odd-and even-order tracks 1-2, 1-3 and others via servo head 2 featuring core width CW equivalent to the double width TW of the disk track, and then the multiplication is carried out through analog multiplier 3. This multiplication signal PM is processed through operational amplifiers 4-1 and 4-2 to which the fixed reference voltage is applied and by making use of the full region of signal PM. Thus cylinder pulse CP of the high S/N is generated through OR circuit 7 to perform the high-accuracy tracking. On the other hand, signal switch circuit 8 is controlled via FF6 which is set and reset by the output of amplifiers 4-1 and 4-2, and thus the signals corresponding to the shift velocity of head 2 in the radius direction are detected. As a result, head 2 can be controlled at the searching time.

Abstract: PURPOSE:To enlarge the grade at the intermediate portion of a screen, whereby obtaining an easy-to-see screen, by forming such that the horizontal variation of the brightness in an unit light emitting region produced through incidence of an electron beam will vary in accordance with specific function. CONSTITUTION:The brightness in an unit light emitting region on the fluorescent face obtained through the incidence of an electron beam is made to vary in accordance with a function; which determines the horizontal variation from an original point or the center of a fluorescent face in accordance with a function of the distance from the original point or dB/dX=-K.X.B (where B: brightness, X: horizontal  distance, K: content). Consequently, the margin of the electron beam landing can be enlarged, by enlarging the grade at the intermediate portion in the screen without varying the grade at the center and the circumference of a fluorescent face, resulting in an easy-to-see screen.

Title: Sheet conveyer and image forming device provided with sheet conveyer
Inventor: SHIRAI MASASHIGE
IPC: B65H85/00
Filed: 1994-06-16
Abstract: PURPOSE:To prevent an improper refeed of a sheet material so as to reduce a loss time when refeed paper. CONSTITUTION:A sheet material after forming an image in a surface is conveyed along a conveying surface and released in a lateral direction along an extension surface by a paper discharge roller 31b. The released sheet material is moved by maintaining a plane-shaped attitude, to collide against a butt part and to stop moving in the lateral direction. Thereafter, the sheet material is freely dropped down and loaded on a loading surface 32a. Here by setting point end drop height h1 in the point end equal to rear end drop height h2 in the rear end, of the sheet material, the sheet material is left as maintaining the plane-shaped attitude, to make its point/rear end lead to the loading surface 32a almost simultaneously. Thus by improving a position and attitude of the sheet material when loaded, thereafter in the case of performing a refeed of paper by arm air paper feeder 50, a good refeed of paper cap be realized. Loading paper and refeeding paper can be performed in a short time.

Title: Method for desulfurizing molten iron
Inventor: KIKUCHI NAOKI
IPC: C21C7/04
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a desulfurizing agent and the productivity of the desulfurizing treatment and to achieve the reduction of slag producing quantity at the desulfurizing treatment by using mixed gas of inert gas and hydrocarbon base gas as the carrier gas and specify the ratio of the hydrocarbon gas to the desulfurizing agent. SOLUTION: This desulfurizing method for molten iron is executed with the ratio of hydrocarbon base gas to a desulfurizing agent of 2.0-50 Nl/kg. The injecting speed of the desulfurizing agent is <=1.0 kg/min/ton of molten iron, and the desulfurizing agent is desirable to be CaO base desulfurizing agent. In the case the injecting speed of the desulfurizing agent is <=1.0 kg/min/ton of molten iron, the ratio of propan gas as the hydrocarbon base gas to the desulfurizing agent (i.e., propan gas flow rate/desulfurizing agent) is made in the range of >=2.0 Nl/kg, to promote the desulfurizing reaction. The reason why the propan gas promotes the desulfurizing reaction, is because oxygen potential in the reaction interface between the molten iron and the desulfurizing agent is lowered.
