Title: Cathode-ray tube
Inventor: OGAWA SHINJI
IPC: H01J29/88
Filed: 1990-04-26
Abstract: PURPOSE:To keep high vacuum condition in the inside of a tube well and extend its service life by forming a conductive coating containing activated carbon to which at least one of boric acid, borates, phosphoric acid, and phosphates is added on the surfaces of inner parts of a tube except a fluorescent plane. CONSTITUTION:A conductive coating containing activated carbon to which at least one of boric acid, borates, phosphoric acid, and phosphates is added is formed on the surfaces of inner parts of a cathode-ray tube. The activated carbon composing such conductive coating effectively adsorbs and removes unnecessary gases in the tube. Consequently, deterioration of a cathode of an electron gun is prevented and its service life is extended and since boron or phosphorus in a prescribed amount is contained in the activated carbon, the inner part material is not oxidized and burned even after frit-sealing process and thus production yield of cathode-ray tube is improved.

Patent JP-S601811-A (JP)
Title: Superconductive coil
Inventor: MITSUNE SUSUMU
IPC: H01F6/06
Filed: 1983-06-20
Abstract: PURPOSE:To prevent easy movement in the axial direction of a superconductive wire by taperng the inner diameters of mutual spools of a pair of layer winding circular superconducting coils receiving mutually attractive or repulsive electromagnetic force and facing tapers each other. CONSTITUTION:Winding shaft sections 3'<4>, 4'<4> are formed in tapered structure. Consequently, when superconducting wires are wound so that mutual coils attract by spools 3, the superconducting wires are brought close to flanges 3' and wound tightly. As a result, there is no space in which the superconductive wires can move toward the flanges 3' on conduction, and there is no normal conductive transfer of coils with the movement of the superconductive wires. When currents in the direction of currents in which the wound coils are repulsed are flowed, electromagnetic force works to the superconducting wires so as to be moved in the directions of the flanges 3''. Since winding shafts are thickened in the direction of the flanges 3'', however, the superconducting wires can not move. Accordingly, there is no normal conductive transfer of the coils with the movement of the superconducting wires even in this case. There are no movement in the axial direction of the superconducting wires and normal conductive transfer with the movement of the wires even on the attraction of mutual coils and on their repulsion in the same manner as the spools 3 in spools 4.

Title: Auto stroboscope device
Inventor: KANAI MASAHARU
IPC: G03B15/05
Filed: 1983-06-20
Abstract: PURPOSE:To prevent over-exposure at a short-distance side by varying the dimming level of an auto stroboscope according to the photographic distance. CONSTITUTION:A potentiometer 2 is coupled with a photographic lens which is operated manually, and a voltage is inputted as the dimming level to a comparator 4. Reflected light from a subject is inputted to the photodiode 6 of an operational amplifier 5. The output of a capacitor 8 is compared with the dimming level by the comparator 4, which outputs a light emission stop signal to a stroboscope circuit 10 when they coincide with each other to stop a discharge tube 12. The meter 2 generates a voltage corresponding to the photographic distance, and this is sent as the dimming level to the comparator, which compares the input with the terminal voltage of a capacitor 7 integrating the quantity of the reflected light. Therefore, the voltage of the potentiometer 2 is set so that the voltage is low at the short-distance side, thus the quantity of light emission is reduced at the short-distance side to prevent over-exposure.
