Abstract: PURPOSE:To obtain excellent aptitude for manufacture and characteristics proper to an in-plane magnetization type recording system in a magnetic recording medium having a magnetic layer on a non-magnetic substrate. CONSTITUTION:A metallic thin-film mainly comprising a magnetic alloy represented by (CO100-xPdx)100-yCry (where at.% is used as the units of (x) and (y), and (x) and (y) are kept within a range of 10<=x<=40 and 5<=y<=25) is employed as a magnetic layer, and a nucleation layer is formed between the magnetic layer and a non-magnetic supporter. The nucleation layer is composed of a composition shown in CrM (where M represents a metallic element having a lattice constant larger than that of Cr and forming a body-centered cubic lattice crystal), and the lattice constant c0 of the magnetic alloy and the lattice constant of the nucleation layer have a relationship in which one is approximately integral times of the other.

Title: Correction of d.c. field distortion in transformer
Inventor: KOUAN TOYOICHI
IPC: H01F27/38
Filed: 1982-07-13
Abstract: PURPOSE:To positively correct D.C. field distortion produced in a transformer, by a method wherein current of second harmonic component to the power source frequency contained in exciting current flowing in a primary winding is detected by a current transformer and a band-pass filter, and output in a variable D.C. source is adjusted to make the current zero. CONSTITUTION:If exciting currents iU, iV, iW are detected at current transformers 3U, 3V, 3W and passed through band-pass filters 4U, 4V, 4W, output signals corresponding to D.C. field distortion amount are obtained in output side of the band-pass filters 4U, 4V, 4W. Variable D.C. power sources 5U, 5V, 5W receive the output signals of the band-pass filters and adjust respective outputs for these signals to become zero and supply D.C. currents to auxiliary windings 6U, 6V, 6W. D.C. field distortion existing in a transformer winding 1 is corrected to zero by D.C. currents supplied to the auxiliary windings 6U, 6V, 6W.

Inventor: RAI YASUKI
IPC: H01L29/78
Filed: 1981-08-05
Abstract: PURPOSE:To execute self-alignment without forming visored projections to a gate oxide film and polycrystal silicon by selectively shaping the polycrystal silicon forming a gate onto a substrate oxide film functioning as a gate insulating film and simultaneously etching the oxide film and the substrate oxide film under a condition that the surface of the polycrystal silicon is oxidized. CONSTITUTION:The silicon oxide film 2 is coated with the polycrystal silicon film 3 forming the gate, and a resist film 4 is shaped at a section serving as a gate region. The exposed polycrystal film 3 not coated with said resist film 4 is removed through etching while using the resist film 4 as a mask. The resist film 4 employed as the mask in a pre-process is exfoliated, and the residual polycrystal film 3 is oxidized from the surface and changed into a surface oxide film 5. Lastly, the substrate oxide film 2 is removed through etching together with  the surface oxide film 5 which leaving only a section coated with the polycrystal  silicon film 3.

Title: Thermal paper
Inventor: OOTA TAKAHISA
IPC: B41M5/28
Filed: 1982-07-15
Abstract: PURPOSE:To provide thermal paper capable of performing multicolor printing through the imagewise heating due to thermal head without carrying out such an operation that paper is transferred at every one color and a color is developed each time under heating by the thermal head, obtained by coating paper with paints forming colors under heating partially at every each color.

Filed: 1994-06-06
Abstract: PURPOSE: To provide a flushable, disposable laminated toilet seat cover which is acted as a moisture shielding material, has a moisture shielding layer being water soluble, and is flushed away. CONSTITUTION: The flushable laminated toilet seat cover 10 is formed by laminating and holding a top layer 14 composed of absorptive cellulose fiber web, a water soluble polyvinyl alcohol film layer 18 having the thickness approximately 1/4-4 mil, and a bottom layer 16 composed of absorptive cellulose fiber web by heat adhesion, etc. The layers 14, 16 have the weight approximately 4-50 lb/rm. The cover 10 is elliptical and has a penetrated opening part 12 in the center. A user lays the cover 10 on the toilet seat with the layer 16 faced to the bottom and sits on the layer 14. When the layer 16 is met with the droplet on the toilet seat, it spreads the droplet into the wider region of the layer 16 by the absorbing action of the capillary action. The water soluble polyvinyl alcohol film layer 18 becomes a barrier for the passing of such droplet.

SOLUTION: At the time of casting the molten aluminum, the actual measured values of the primary crystallized temp., eutectic temp. over-cooling degree, etc., are obtd. with the thermal analysis. On the other hand, the calculated value of the primary crystallized temp., eutectic temp., over-cooling degree, etc., are obtd. with regression equation based on the control chemical component analyzed values with the chemical analysis of the molten metal. While comparing the actual values with the calculated values, these differences are obtd. The judgement of the shrinkage hole is executed whether these different values are in the permissible range or in the boundary having no problem to the preset shrinkage property, or not. Further, as necessity requires, the above actual measured values or the calculated values, and the values in the molten metal having no problem related to the shrinkage property, are compared, and then, further accurate prosumption of the shrinkage property can be obtd.

Title: Charging method for secondary cell
Inventor: KANO TOSHIHIKO
IPC: G01R31/36
Filed: 1990-05-15
Abstract: PURPOSE:To prevent a decrease in the life of a secondary cell due to overcharging by allowing quick charge only when predetermined power is consumed from the cell or the cell is replaced after the fully charged state of the cell is detected. CONSTITUTION:A charging type is switched by a DC/DC converter 3 in response to a command signal generated from a charge/discharge controller 8. the controller 8, if it detects a fully charged state of a secondary cell 1 during quick charging, stands a full charge flag, and outputs a command signal to the converter 3 to switch the type to a trickle change. The full charge flag inhibits quick charging to the cell while it is being stood, and the controller 8 is restricted by the flag. Accordingly, while this flag is being stood, a switching command signal for switching the trickle charge to the quick charge is inhibited by the controller 8 for the converter 3. The detection of the full charge state of the cell 11 is detected by so-called - V type.

Title: Picture processing system
Inventor: MASUDA YUKIO
IPC: H04N1/40
Filed: 1984-06-19
Abstract: PURPOSE:To distinguish accurately half-tone picture areas and character picture areas from each other to improve the picture quality by providing a simple-constitution erroneous discrimination preventing circuit when the binary picture block discriminating system is executed. CONSTITUTION:A picture quality discriminating circuit 15 reads out contents of a picture memory 12 successively with a block consisting of mXn-number of picture elements as a unit and counts the number of white or black picture elements. If the counted value is equal to ''0'' or mn or approximates ''0'' or mn, this block is judged as a half-tone picture area. At this time, an erroneous discrimination preventing circuit 20 reads out contents of a picture memory 14 successively with one block as a unit and compares them with contents of a fixed threshold pattern memory 21 and discriminates the block as a half-tone picture area if the degree of coincidence is high. If this discrimination signal indicates a half-tone picture area, a selecting circuit 16 discriminates the noticed block as a half-tone block, but otherwise, the circuit 16 discriminates it as a half-tone block or a character block in accordance with the discrimination signal from the circuit 15. Picture data is transferred from the memory 14 to an output picture memory 18 in case of the half-tone block, and picture data is transferred from a memory 12 to the memory 18 in case of the character block.
