Title: Manufacturing process of magnet sheet
Inventor: KOETANI KOUJI
IPC: H01F7/02
Filed: 1977-12-09
Abstract: PURPOSE: To heighten the surface magnetic flux density, by making the magnetic orientation of a magnet sheet having magnetic anisotropy oblique to the surface of the sheet.  
     CONSTITUTION: A mixture containing scale-shaped ferrite grains treated to magnetic anisotropy and rubber or synthetic resin is rolled, thereby making the magnet sheet 4 which is magnetically anisotropic and shows ferromagnetism in the direction of the thickness. Such magnet sheets 4 are laminated with one another. The laminated piece 5 is obliquely cut off, thereby obtaining magnet sheets 6 of magnetic orientation oblique to the surfaces. Then, the equal surfaces of the sheets 6 are magnetized. The surface magnetic flux density varies depending on the angle of the magnetic orientation and takes its maximum value at an angle of 30 to 45°. A different method of making the magnetic orientation oblique is to apply an oblique field to the magnet sheet 4 or to use ferrite grains having ferromagnetism oblique to the longitudinal direction.

Title: Variable gain equalizer circuit
Inventor: FUJIWARA NOBUO
IPC: H03H11/24
Filed: 1980-10-23
Abstract: PURPOSE:To eliminate the distortion generated in a three-terminal variable resistance and to make the gain variable, by grounding the middle point of this resistance through a resistance and providing a circuit, which converts an input signal to a current, in one rest terminal and providing a mirror circuit, which generates the same current, in the other terminal. CONSTITUTION:The signal inputted to transistors TR1 and TR2 constituting a complementary emitter follower circuit is converted to a current i1 having a value proportional to the reciprocal of the sum between a resistance R3 connected to emitters and a resistance R4 in the side of one terminal of a tree-terminal variable resistance 7. The current i1 is outputted as a current i2, which has the same value as the current i1 and has the direction opposite to that of the current i1, from an output terminal B by inversion current mirror circuits 5 and 6. The current i2 is outputted as a voltage proportional to an impedance element Z2 and a resistance R5. The current flowed to the variable resistance 7 can be ignored because it corresponds to the difference between currents i1 and i2, and distortion is not generated for the output.

Title: Detecting method and device for direction
Inventor: OKADA TOKUJI
IPC: G01V7/04
Filed: 1980-10-23
Abstract: PURPOSE:To measure a direction at a high sensitivity in detection for robot operation, by a method wherein a photoconductive part, which changes direction in accordance with the direction of an operating force, such as gravity, magnetism, is irradiated with a light to form an image on a light-receiving surface, and the length and position of the image on the light-receiving surface are detected. CONSTITUTION:A disc 2 supported at 2 points (3b, 3b), which turns around an axis passing a center of a toroidal ring 1 and meeting the rotary shaft thereof at right angles, is mounted at the inside of the toroidal ring 1 freely turning by supporting at 2-points (3b, 3b), and a photoconductive part 4 is located at the center of the disc 2. The photoconductive part 4 is irradiated with a light from a point light source L to detect a length and a position of a projection image 5 of the photoconductive part 4 formed on a light-receiving surface S perpendicular to a line connecting the light source L and the disc center. On the basis of the data, a value of a parameter representing the direction of the photoconductive part 4 is determined by a given procedure. The attachment of a weight 6 at the point of the disc 3, where a turn radius attains a maximum, detects a gravity direction or an acceleration direction, and the attachment of a magnet 6 to one side of the disc 2 and of a weight having the same weight as that of the magnet 6 to the other side detects the direction of a magnetic pole.

Inventor: IZAWA NOBUYUKI
IPC: H01L21/322
Filed: 1988-06-15
Abstract: PURPOSE:To prevent mechanical strength from being lowered and performance of a device from being worsened when a dislocation row is formed in a semiconductor substrate by a method wherein, after ions of oxygen or nitrogen have been implanted into a part other than a device formation region of the semiconductor substrate, the device is formed. CONSTITUTION:Oxygen O is introduced down to a depth of several mum to several tens of mum with reference to a bottom face 3 of a semiconductor wafer 1, e.g., by utilizing channeling and at a high energy of 1 MeV or higher; the oxygen O is set to a concentration of e.g., 1.2 to 2.0X10<18>cm<-3>. Then, a resist film 5 is formed selectively in such a way that only peripheral regions 4 in a semiconductor device formation face 2 of the semiconductor wafer 1 are exposed; ions of oxygen O are implanted into the semiconductor device formation face 2 of the semiconductor wafer 1 ; after that, the resist film 5 is removed. By this setup, it is possible to restrain a dislocation row from being generated by a pinning effect; since oxygen or nitrogen is not implanted into a device formation region, the oxygen or the nitrogen whose ions have been implanted does not at all affect a characteristic of a semiconductor element.

Title: Polymer dispersion liquid crystal composite film, its production and polymer dispersion liquid crystal optical element using that
Inventor: TAMAYA AKIRA
IPC: G02F1/1333
Filed: 1994-06-30
Abstract: PURPOSE:To obtain good characteristics with small hysteresis and high contrast by forming a composite film comprising a polymer matrix and a liquid crystal which is carried on fine particles with an anisotropic shape and dispersed and held in the polymer matrix. CONSTITUTION:The liquid crystal dispersed in the polymer matrix is carried on fine particles having an anisotropic shape (such as nonspherical shape) and is formed into liquid crystal drops according to the shape of fine particles. Namely, when the polymer matrix precursor is polymerized to cause the phase separation between the liquid crystal and the polymer matrix, the liquid crystal grows with the fine particles as nuclei. Therefore, the shape of liquid crystal drops necessary to obtain the optimum electro-optical characteristics is controlled by changing the shape and kinds of fine particles. When the fine particles are in an anisotropic shape, the liquid crystal molecules are easily oriented in a specified longitudinal direction and the liquid crystal drops are easily made to have an anisotropic shape. Thereby, the optimum electro-optical characteristics with high contrast and small hysteresis are obtd.

Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To purely prevent an original at an original reading position from jamming, which occurs when the upper surface of an original platen is not completely closed with an original cover. SOLUTION: A photosensor 17 is attached to a guide plate 10, supported at the original reading position in an original moving move to which platen glass 22, is positioned in an upwardly swingable state, and a detection plate 18 detected by means of a photosensor 17 is fixed on the main body side of an original reader. Before starting the original moving mode in which images are read from an original while the original is transported on an original transport path, the turned-on/off state of the photosensor 17 is detected and whether the clearance between the guide plate 10 and the upper surface of the platen glass 22 is appropriate for making the guide plate 10 closely adhere the original to the upper surface of the platen glass 22 is discriminated.  When the clearance between the guide plate 10 and upper surface of the glass 22 is not appropriate, the execution of the original moving mode is inhibited.
