Abstract: A plate material for a shadow mask, consisting essentially of iron or of iron and nickel and having a surface configuration which stabilizes the adhesion between the plate material and a photoresist and improves the adhesion between the plate material and a negative pattern in the process of producing a shadow mask, thereby enabling improvements in the quality and the productivity, and which causes no annealing adhesion in the shadow mask softening annealing step in the process of producing a color picture tube. The plate material has a surface roughness Ra and a surface roughness projection condition Rsk, which are defined as follows:Ra: from 0.3 to 0.8.mu.mRsk: +0.1 or morewhere Ra is the surface roughness specified in JIS B 0601, and Rsk is a value representative of the relativity of an amplitude distribution curve to a mean line, i.e.

Abstract: In an Fe-base alloy, Ni is contained by 28 to 34% by weight and Co by 2 to 7% by weight with an average grain size of 30 .mu.m or less. 60 to 95% of crystal grains are oriented in a range of .+-.5 to 45 degrees deviated from the ideal orientation of {100} [001]. Resultant low thermal expansion of the alloy assures high doming characteristics of a shadow mask made thereof.

Abstract: A set of input and output buffers are arranged in an outer peripheral portion of a semiconductor chip and a macro region and a set of internal gates are arranged in an inside portion of the semiconductor chip. The input and output buffers are connected to the internal gates through a boarder region between the macro and the set of the internal gates.

Abstract: The present invention relates to a metal-working lubricating oil having improved lubricity due to the addition of certain tri-esters of tri-mellitic acid to said oil. The oil thus formed is particularly well suited as roll oil lubricant in the cold rolling of stainless sheets and foil.

Abstract: The invention relates to a BiCMOS or bipolar/CMOS hybrid integrated circuit device which has both bipolar transistors and MOS transistors on the same semiconductor substrate. An output circuit of the device having a push-pull configuration is constructed of two bipolar transistors Darlington-connected with each other arranged at the upper push-side and a MOS transistor arranged at the lower pull-side. A Schottky diode is interposed between the power supply line and the Darlington-connected bipolar transistors, thereby preventing the flow of currents from an output node into the output circuit. The output circuit also includes a clamping circuit of a Schottky diode for preventing the output bipolar transistor from being saturated and, a discharging circuit of a Schottky diode and a resistor connected in series, for discharging the charges stored in the base of the same bipolar transistor.
