Title: Release type dot printer head
Inventor: OCHIAI KUNIAKI
IPC: B41J2/26
Filed: 1982-12-20
Abstract: PURPOSE:To save the power consumption along with a higher speed by fixing a plurality of cores being arranged at an interval so that the joint area of a core fitting section with a core holding surface can be made larger than the sectional area of a core columnal protrusion. CONSTITUTION:A plunger 31 of an armature 23 is attracted to cores 25 with a permanent magnet 22 and the magnetic flux is cancelled with the excitation of an electromagnetic coil 27 so that the armature 23 turns with a spring 34 on the fulcrum 33 to perform a printing with a needle 32. Then, the cores 25 are arranged at a space S while the joint area of a fitting section 26 with a core holding surface 24 is made large and the length H thereof short. This can eliminate the leakage of magnetic flux between the cores 25 and prevent the leakage of magnetic flux with a shorter route from the permanent magnet 22 to the armature 23. It also checks increase in the power consumption due to magnetic interference achieving a higher printing speed.

Filed: 1988-09-07
Abstract: PURPOSE:To obtain same light transmissivity and to eliminate coloring by equipping a picture element with a color filter of one color among red, green, and blue and making the capacity ratio of liquid crystal and a nonlinear element different among the colors of filters. CONSTITUTION:The picture element 13 composed of the nonlinear element 11 coupled in series with the liquid crystal 10 is equipped with the color filter of one color among red, green, and blue, and picture element dot trios are arranged in a matrix.

Title: Carbon fiber/carbon composite material
Inventor: AIBA YASUHIRO
IPC: C04B35/83
Filed: 1989-08-30
Abstract: PURPOSE:To improve the tensile strength between layers while keeping the heat conductivity and thermal expansion coefficient identical to those of the conventional 1D material by forming the composite material from the bundled body obtained by winding carbon fiber on a bundle of carbon fiber and a carbon matrix. CONSTITUTION:A carbon matrix is formed by the resin impregnation and carbonization method, CVD, etc., on the bundled body obtained by winding carbon fiber 2 on a bundle 1 of carbon fiber. Since the carbon fibers are interlaced with each other in the bundled body, the strength between the layers (in two directions x1 and y1 at right angles to the bundle 1) is increased. As the fiber bundles are arranged in the thickness direction (vertical), the heat conductivity of the C/C composite material in the direction of the carbon fiber (z1 direction) is increased, and the thermal expansion coefficient at right angles to the carbon fiber (x1 and y1 directions) is also increased.

Filed: 1989-08-30
Abstract: PURPOSE:To enable highly-precise, easy and simple determination of the plane distribution of a refractive index in the width direction and in the depth in the vertical section of an optical waveguide by forming an inclined flat surface wherein the depths of waveguides are changed in a stepped manner in the direction of traversing them. CONSTITUTION:A resist patterns 5 is formed on an LiNbO3 substance 2 by photolithography. Next, Ti 3 is evaporated or sputtered on the pattern 5 from above the pattern. Then, the pattern 5 is removed by immersion in acetone and a pattern of the Ti 3 is formed on the substrate 2. Thereafter, heat treatment is applied in an O2 atmosphere and thereby the Ti 3 is diffused thermally into the substrate 2. In this way, optical waveguides 4 of which the refractive index of the thermally diffused parts is higher than that of other parts of the substrate 2 are formed in the substrate 2. The substrate 2 thus prepared is stuck and fixed on a jig 6 having a slanting surface 6a so that the slanting surface 6a is parallel to the waveguides 4. Lastly, the substrate 2 fitted on the jig 6 is ground specularly in a plane being parallel to the bottom surface 6b of the jig 6, so as to form a ground surface 7 which is a slanting surface having an angle of inclination of theta = 1 deg. to the substrate 2 and being parallel to the waveguides 4, and thus a sample for measurement is prepared.

Title: Nuclear fuel element
Inventor: MOTOMIYA TAKEO
IPC: G21C3/28
Filed: 1988-09-09
Abstract: PURPOSE:To prevent the rise of the central temp. of nuclear fuel pellets formed by boring a central hole to the center of pellet laminates by alternately laminating the nuclear fuel pellets and metallic disks bored with a through-hole of the same diameter as the diameter of the nuclear fuel pellets. CONSTITUTION:The hollow-shaped nuclear fuel pellets 3 and a metallic rod 6 inserted to the central axis of the metallic disks 5 are fitted into the central hole 4 of the metallic disks 5 having a through-hole adjacent to the nuclear fuel pellets 3. Heat transmittance is, therefore, effected from the central part of the pellets to the outer peripheral part and the rise of the central temp. of the pellets is suppressed. However, the hole 4 at the central axis of the metallic disks 5 of room temp. is previously given some gap (several microns) by taking the thermal expansion in the circumferential direction of the metallic rod into consideration. The thermal expansion in the axial direction is relieved by a spring 7. Since the metallic bar 6 is inserted into the nuclear fuel pellets 3, there is an effect of preventing the chipping of the fuel pellets 3 as well.

Abstract: PURPOSE:To obtain a fine rotary movement of high accuracy and high resolving power, by providing a contractive conversion mechanism causing the displacement larger in a nut side while smaller in a disc side by a tilting piece arranged between the nut and the disc. CONSTITUTION:A pulse motor 11, being rotated, transmits its turning effect to a threaded bar 13, and its rotation advances a nut 15 straight in one direction along the threaded bar 13. And the nut 15, if it moves to the position of a supposed line, tilts a lever engaging pin 26 to be moved through a feed lever 19 of the nut 15 while also a drive engaging pin 25 to be similarly moved in an equal direction. Here a horizontal piece 23 tilts moving about a small thickness part 24 serving at the supporting point. Accordingly, on the basis of so- called contractive conversion action, in which a tilt movement in a side of the drive engaging pin 25 is smaller than the tilt movement in a side of the lever engaging pin 26, a disc 20 performs a fine rotary movement about a center point 35 serving as the base point in the counter clockwise direction by the contractively converted displacement.
