Title: Gas discharge display panel
Inventor: YOSHIKAWA KAZUO
IPC: H01J11/12
Filed: 1978-12-15
Abstract: PURPOSE: To eliminate deformation by cutting off external pressure with cover glass and preventing it from being applied to a substrate.  
     CONSTITUTION: Two-phase meander type X electrode groups are formed on the surface of the first substrate 11. The cover glass 13 adheres to the first substrate 11 by the seal material 14 and the exhaust pipe 15 is provided on a part of the substrate. Discharge gas fills the space between the cover glass 13 and the first substrate 11. Since external pressure is cut off by the cover glass 13 and is not quite applied to the second substrate 17, no deformation occurs. As a result, by the peripheral section of the second substrate 17, i.e. a few spacers 19 outside the display screen, the gap length between both substrates can be always maintained in fixed dimensions.

Filed: 1985-07-17
Abstract: PURPOSE:To obtain a steel bar having the high strength and high toughness uniform over the entire length by controlling the pearlite transformation temp. of the steel bar subjected to hot rolling by blast and mist spraying in a specific temp. region. CONSTITUTION:The blast is blown to the steel bar subjected to hot rolling uniformly in the circumferential direction over the entire length thereof in the temp. region of 950-500 deg.C. Mists are sprayed thereto uniformly in the circumferential direction by using a mist spray. The cooling of the steel bar is controlled by combining the above-mentioned operations. The pearlite transformation can be started in the temp. range of TC-TC+40 deg.C by such uniform speed cooling when the critical temp. tangential to the pearlite transformation initiation line of the CCT curve of the steel bar is designated as Tc. The max. temp. during transformation can be suppressed to TC+80 deg.C. The mechanical characteristics uniform over the entire length of the steel bar are thus rendered to the steel bar.
