Title: Hexagonal system ferrite magnetic powder
Inventor: MIYABAYASHI MASAYUKI
IPC: H01F1/11
Filed: 1985-09-05
Abstract: PURPOSE:To make it possible to maintain a specified coercive force by a method wherein a part of Fe as a basic component is substituted by Co and Ti, and then, a part of Co is further substituted by Zn so as to miniaturize the diameter of particles. CONSTITUTION:The hexagonal system ferrite magnetic powder, whose composition is expressed in a general formula: MO n (Fez-zyCoy(1-x)ZnyxTiyO3) (However, M indicates at least one of Ba, Sr, Pb, and n=5.4-6.0, o<x<1, and 0<y<0.2), has composite ferrite consisting of Ba ferrite, Sr ferrite, pb ferrite or more than two kinds out of Ba, Sr or Pb as basic components. A part of Fe is substituted by Co or Ti, then a part of Co is substituted by Zn. The substitution with Co and Ti has an effect of controlling coercive force and increase the coercive force with increase in the amount of Zn when a part of Co is substituted by Zn and the diameter of particles is kept the same. Thus, it is made possible to control the coercive force and the diameter of particles independently and to maintain a specified coercive force with reduced diameter of particles.

Title: Picture processing unit
Inventor: ISHII HITOSHI
IPC: H04N1/419
Filed: 1989-07-31
Abstract: PURPOSE:To quicken the decoding time by designating each start point and each end point in horizontal and vertical directions of a segmented picture so as to start decoding and interpolating a level between change points when the period is not blank period between density change points. CONSTITUTION:Each start point and each end point in horizontal and vertical directions of a segmented picture are designated. A Huffman decoder 9 uses a count circuit 10 so as to add the distance of density change points of picture information read from a storage device 8 in terms of picture element counter. This processing is repeated till the processing is coincident with that in the vertical direction and when the start point is exceeded, the processing is traced back to one preceding density change point and a change point, decoding circuit 11 starts the decoding of the change point from the density change point when the size is coincident. When the density change point does not exists in the black period, a horizontal interpolation circuit 13 interpolates a change point period. The addition by the picture element counter is continued even during the decoding of the change point and the decoding is finished when the segmentation end point is exceeded. This processing is repeated till the vertical segmentation end point by a line counter and a vertical direction interpolation circuit 15 decodes the undecoded picture element.

Title: Female side terminal fitting
Inventor: SEKO TOMOMI
IPC: H01R13/11
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To raise contact pressure of an elastic contact piece against counterpart terminal fitting. SOLUTION: A pair of elastic contact pieces 12 standing opposite vertically to each other are formed so as to each have a U-shaped cross section and a base end part of each of the elastic contact pieces 12 is joined to a cylindrical part 11. Elastic reinforcement walls 13 are thereby formed along the flexural deformation direction of the elastic contact pieces 12 from a joint part to the cylindrical part 11 in the elastic contact pieces 12. When male side terminal fitting C is inserted between the elastic contact pieces 12, the elastic contact pieces 12 are opened upwardly/downwardly while deform the elastic reinforcement walls 13 in the direction parallel to their wall surfaces.  Accordingly, the same elastic force as that of an increased plate thickness acts on the joint part of the elastic contact pieces 12, and contact pressure against the male side terminal fitting C can be thereby raised.

Abstract: PURPOSE:To perform processing without causing important trouble, by providing a means of detecting whether a signal varies in amplitude within a prescribed period after the start of a backward run. CONSTITUTION:A backward read instruction and the output of a signal amplitude detecting circuit are used and when the backward read instruction is sent, a monostable multivibrator 10 and a pulse generating circuit 12 output a detection pulse to a line 120 within a constant time after the backward read instruction is generated. On the other hand, a monostable multivibrator 22 generates a pulse with constant time width similarly from the output of a signal-amplitude detecting circuit 20 and if signal amplitude is not detected until the generation of the detection pulse, an FF40 is set with the detection pulse through the operation of an inverter 20 and an AND circuit 30, judging that the device has fault. The output of the FF40 is inputted to an encoder circuit 50 together with a signal of a check on another device sent from a line 700, and its output is sent to a CPU70 through a channel 60.

Title: Magnetic recorder
Inventor: YUZUSU KEIICHIROU
IPC: G11B5/66
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium of extremely low noise by parting magnetic particles from this substrate by part of a nonmagnetic base material and forming substantially one layer parallel with the main surface of a substrate. SOLUTION: The magnetic particles 22 are parted from the substrate 1 by part of the nonmagnetic base material 21 and do not come into contact with the substrate 1. The magnetic particles 22 are preferably larger in the average grain size in a perpendicular direction than the average grain size of a horizontal direction. The magnetic particles 22 form one layer substantially parallel with the main surface of the substrate 1. This fact evidences that the displacement D (the difference in the heights between the centers of the magnetic particles 22) in the perpendicular direction of the magnetic particles 22 is below the average radius in the perpendicular direction of the magnetic particles 22.  The arrangement of the nonmagnetic base material 21 between the substrate 1 and the magnetic particles 22 is executed by sputtering only the nonmagnetic base material in an initial time, then executing two-dimensional simultaneous sputtering at the time of executing the two-dimensional simultaneous sputtering by using, for example, a metallic material target and a nonmagnetic base material target.

Filed: 1984-09-19
Abstract: PURPOSE:To reduce direct sound and reflective sound from a cooling fan and engine body as a sound source by providing an exhaust passage for exhausting upward the blow from a cooling fan. CONSTITUTION:An exhaust port 10 is provided in the rear on the upper face of an intermediate cover 5 between a radiator and small holes. When reduction of the noise from an engine and cooling fan is desired to be achieved, an exhaust passage H is formed in the rear of a radiator 2 by covering the small holes 6 with a flat plate 7 and closing a window 8 by means of a freely opening/ closing lid 9. Therefore, the blow from a cooling fan 3 is exhausted from the exhaust port 10 as upward flow through the exhaust passage H after passing through the radiator 2. Thereby, reduction of noise can be achieved by changing the direction of blow from the horizontal to the upward flow.
