Title: Circuit element forming substance of hybrid ic substrate
Inventor: ITO TAKATOSHI
IPC: H05K1/09
Filed: 1988-06-08
Abstract: PURPOSE:To improve a circuit element forming substance raw material in affinity for an organic solvent and increase a circuit forming solution in a solid content when the circuit forming solution is prepared so as to improve a dispersion in stability with time by a method wherein particle faces of the circuit element forming substance raw material are coated with polymer. CONSTITUTION:Microparticles formed of particles of circuit element forming substance raw material whose surfaces are coated with polymer are dispersed into an organic solvent of low vapor pressure to form a circuit forming solution. Therefore, not only the microparticles are improved in dispersion stability but also the circuit forming solution hardly causes clogging of a ink jet nozzle. And, the circuit forming solution can be optionally varied in a solid content and increased in a metal content, so that a circuit pattern of low sheet resistance can be formed, and moreover microparticles tens nm in diameter whose surfaces are coated with polymer can be manufactured. By this process, the stability of a dispersion with time can be improved.

Title: Manufacture of superconductive magnet
Inventor: OKURA KENGO
IPC: H01F6/06
Filed: 1985-06-28
Abstract: PURPOSE:To remove quenching below rated magnetic field, by vacuumizing a wound coil to remove air and impurities inside the coil and making the winding fit by heating performed during the vacuumizing process, and concurrently uniformalizing or eliminating residual stress inside the coil. CONSTITUTION:A coil, which is obtained by closely winding a NbTi wire with tension applied on a bobbin, is heated at temperatures of 40-200 deg.C and vacuumized for long hours in a vacuum container. Thereafter, the same kind of gas as coolant liquid for magnet is introduced into the vacuum container in order to replace the air, staying between gaps of the NbTi wire, by the above- mentioned gas. Hence, exothermic elements in the coil, that is, air and impurities are beforehand drawn out, and layer insulating materials, serving as materials composing the coil, and an insulating layer enameled on the wire surface are softened by heating to become fit to each other, and residual stress inside the coil, which is connected with the motion of wires during excitation, is also reduced, and therefore stable operation of the coil is obtained, with the quenching being prevented in the state below the rated magnetic field.

Abstract: PURPOSE: To increase the resistance to high temperature oxidization and resistance to abrasion of the piston ring, by providing a ring groove on the piston material and filling this groove by plasma-spraying an alloy powder of Cr-C-Fe.  
     CONSTITUTION: Piston ring material 1 is made of a spherical graphitic iron cast and has on its outer surface a ring groove 2 whose cross section is trapezoid. This is rotated and is plasma-sprayed with an alloy powder containing Cr, 55W70%, C, 3W9%, and Fe for the remaining part. Ring groove 2 is filled with this plasma- sprayed alloy. Then, its outer surface is ground by a cylindrical grinding machine, and thereby a piston ring of the desired shape and size is obtained. At this time, the angle θ to be formed by the two sloping lines of the cross section of ring groove 2 is set effectively more than 100°. By this, high adhesion can be secured between the plasma-sprayed material and the piston ring material, and it is possible to manufacture piston rings excellent in resistance to abrasion at low cost.

Title: Optical fiber bundle
Inventor: NAKAHARA SHINICHI
IPC: G02B6/44
Filed: 1984-07-11
Abstract: PURPOSE:To remove crosstalk light and transmit an image with high resolution by forming an optical fiber bundle of optical fiber element wires which have a light shield layer on the surface of a clad part partially or entirely. CONSTITUTION:The light shield layer 8 is formed on the clad part 7 of the optical fiber element wire 5 partially or entirely by vapor-depositing aluminum, etc., extremely thinly (to hundreds of Angstrom ). Element wires 5 having the light shield layer 8 are bundled into the optical fiber bundle. Therefore, there is no crosstalk light due to leak coupling accompanying light propagation and light projected from a projection side is accurately as much as light incident on an incidence side. Thus, crosstalk light is removed and an image with high resolution is transmitted.

Filed: 1986-06-19
Abstract: PURPOSE:To form a finely patterned masking layer and to form patterned semiconductor regions finely and at a high density, by etching a masking material layer in a delineative manner with ion beams to provide the patterned masking layer. CONSTITUTION:A layer of a masking material 5 subliming at a temperature higher than the surface of a semiconductor substrate 2 is formed on the semiconductor substrate 2. The masking material layer 5 is etched by application of ion beams 7 so that a patterned masking layer 15 is formed therefrom. Then, the semiconductor substrate 2 masked with the patterned masking layer 15 is sublimed so that patterned semiconductor regions 14 are formed on the surface of the substrate. Thus, since the patterned masking layer 15 is formed by etching the masking material layer in a delineative manner with ion beams 7, the patterned masking layer 15 can be patterned finely and, therefore, the patterned semiconductor regeions also can be formed finely.

Title: Developing device
Inventor: IWAMASA AKIMASA
IPC: G03G15/09
Filed: 1987-06-10
Abstract: PURPOSE:To prevent a photosensitive surface from being flawed, and to prevent crests of the developer from being pressed to the photosensitive surface at the time of developer replacement, by allowing the magnetic pole of a developing roll to face the photosensitive surface at the time of normal use and setting this magnetic pole to the position, where it does not face the photosensitive surface at the time of developer replacement. CONSTITUTION:When the developer is normally used, crests of the developer rise on the magnetic pole of a developing roll 7 and are pressed to the photosensitive surface of a photosensitive body 1 because the magnetic pole is arranged to face the photosensitive surface of the photosensitive body 1. As the result, toner is efficiently pressed and transferred to the photosensitive surface to obtain a good image quality. The life of carrier in the developer expires in a developing device 2 by the use. When carrier whose life expires is recovered, a moving handle 19 to move the position of the magnetic pole is operated to shift the magnetic pole of the developing roll 7 from the position where it faces the photosensitive surface, and another magnetic pole is allowed to face a blade 9. In this state, the photosensitive surface is not flawed because crests of the developer are not pressed to the photosensitive surface.
