IPC: H01F1/34
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain a high-permeability oxide magnetic material in which crystal particles are made uniformly large and by which a high-resistivity grain boundary layer is formed by a method wherein a main component is composed of Fe2 O3 , MnO and ZnO and P2 O5 as a subcomponent in a specific ratio is contained in the main component. SOLUTION: A main component is composed of 52 to 53mol% of Fe2 O3 , 24 to 28mol% of MnO and 19 to 24mol% of ZnO, and 0.3 to 1.5wt.% of P2 O5 as a subcomponent is contained in the main component. Thereby, the growth of particles is promoted, and a crystal particle size is made uniform. As a result, it is possible to obtain a material which can be fired at a temperature lower than a temperature to volatilize zinc, which obtains an excellent characteristic even in a (small) product having a large specific surface area, which eliminates an irregularity in a characteristic between products, which does not require a complicated process such as a burying process, which is low-cost and which is excellent.  In addition, the texture of a fired body reduces the number of pores inside a particle, the movement of a magnetic domain wall is made smooth, a high permeability and a low loss can be obtained, high-concentration P2 O5 is precipitated in a grain boundary layer, the resistivity of the grain boundary layer can be made high, and an eddy-current loss can be reduced.

Title: Wire dot-type printing head
IPC: B41J2/28
Filed: 1992-03-13
Abstract: PURPOSE:To ensure that an armature is opened optimally at a timing to realize such an opening and thereby improve printing quality by providing a rigidity correction mechanism which varies the rigidity of a mechanical vibration part consisting of an annular elastic member and a printing wire and an armature with positions in a circumferential direction. CONSTITUTION:An auxiliary spring 10 has plate-like protrusions corresponding to a leaf spring 4 in an annular manner. In addition, the position of the inner circle of the protrusions is larger in diameter than the position of the inner position of the leaf spring 4. Further, the diameter of the inner circule position is large near the center line C of a printing head, and is small in proportion to the vertical distance which becomes wider from the center line, thus changing the rigidity. The auxiliary spring 10 is arranged on the printing head so that the spring 10 comes in contact continuously with the surface where a ring yoke with the leaf spring 4 is provided. Therefore, if the armature 5 is attracted, the auxiliary spring 10 becomes flexible with the concurrent flexing action of the leaf spring 4, and thereby the armature 5 is open at an accelerated timing after the application of the electric current. The tongue piece 10a of the plate-like protrusion of the auxiliary spring 10 separates the leaf spring 4 from the auxiliary spring 10, if the tongue piece 10a hits a stopper 12 after the release of the armature 5.

Title: Blurring corrector
Inventor: OKI MITSUHARU
IPC: G06T7/20
Filed: 1991-03-19
Abstract: PURPOSE:To improve blurring correction accuracy without increasing the circuit scale of the blurring corrector. CONSTITUTION:While the moving image picture of a current field is inputted, a moving vector detection circuit 20 calculates first moving vector V1 of the current field picture for the preceding field picture with the first accuracy. During the period of the vertical interval after signal input, a second moving vector detection circuit 30 calculates the second moving vector V2 with the second accuracy higher than the first accuracy. A vector adder 34 adds the vectors V1 and V2 and synthesizes a final moving vector Vf. A second control circuit 71 outputs a reading address corresponding to the moving vector Vf to a field memory 41, and the field memory 41 outputs the blurring-corrected picture signal. Therefore, the increase of circuit scale can be suppressed and the blurring correction accuracy can be remarkably improved while housing the blurring correction circuit in one chip.

Title: Vinyl chloride resin of excellent extrudability
Inventor: YAMANE KAZUMASA
IPC: C08F14/06
Filed: 1984-03-21
Abstract: PURPOSE:A vinyl chloride resin of markedly improved extrudability, having a specified average particle diameter and a specified void volume. CONSTITUTION:A vinyl chloride resin having an average particle diameter >=150mum and a void volume at 31-1,011psi >=0.15cc/g. When said void volume is below 0.15cc/g, the vinyl chloride resin will have a worsened gel forming property and deteriorated physical properties undesirably. When said volume is 0.19cc/g or above and the bulk density is 0.54/cc or above, particularly desirable results can be obtained because an extrudability-improving effect from both the bulk density and the average particle diameter can be realized and there is also an effect that the molding can exhibit the same physical properties as those of the conventional. The reason why said resin can show markedly improved extrudability is as follows. When the average particle diameter is large, the powder flow is increased, which in turn increases the amount of a resin fed to an extruder per unit length of time.

Title: Fuel injection control device
Inventor: SAKAI YASUHIRO
IPC: F02M69/00
Filed: 1994-03-25
Abstract: PURPOSE:To dispense with a negative pressure introduction passage by obtaining a ratio of a fuel injection amount between the fuel whose pressure is highered than the intake pressure by the specified value and the pressure whose pressure is highered than the atmospheric pressure by the specified value for correcting the fuel injection amount. CONSTITUTION:During operation of an engine, an ECU 21 determines a proper fuel amount according to an engine condition and a vehicle condition, and computes an injection time of a fuel injection valve 7. In order to inject a target amount which is adjusted in pressure with reference to atmospheric pressure, the fuel injection time must be corrected. As for the fuel adjusted in pressure with reference to an intake pressure, the injection amount is proportional to an opening time of the fuel injection valve 7. A ratio of the injection amount is obtained in the case that the fuel adjusted in pressure with reference to the atmospheric pressure and the fuel adjusted in pressure with reference to the intake pressure are injected simultaneously. The target injection time is corrected with the obtained ratio. An accurate injection amount is thus obtained irrespective of fluctuation of the intake pressure.

Abstract: PURPOSE:To obtain a strong plastic magnet having magnetic poles n minute pitches, by application of a small-diameter heat source such as laser beams to a part of a plastic magnet original material to be magnetized, to obtain local fusing, and arranging the directions of magnetic characteristics in the permanent magnet powder for only the fused part. CONSTITUTION:Pointed-end parts 11 and 12 of a yoke 3 are positioned in a point symmetry of 180 deg. with an original material 1 of a plastic magnet supported, and small gaps 8 and 9 are provided between the pointed-end parts 11 and 12 of a yoke 3 and the original material 1. The slit 13 extends in the axial line direction of a right-sided pointed-end part 11, passing into the part 11, and laser beams 14 are made passable through the slit 13. Since a small- diameter heat source such as laser beams is applied in magnetization to locally fuse only the part, strong magnetic force can be applied. Using laser beams in particular enables the fused part to be limited within an extremely small range, and therefore many magnetic poles can be produced by very minute pitches.
