Abstract: PURPOSE:To prevent generation of wrinkles on the mesh electrode surface or a disorder of the collimation lens, etc., by furnishing a step sunken a little more than the thickness of the mesh electrode fixing flange, at the end of the bulb wall where the plate of a glass bulb is to be airtight sealed. CONSTITUTION:The inside of the top surface of a glass bulb 1 is made lower by t2 than the thickness t1 of the flange of a mesh ring 8 (as t2=t1+0.01-0.02mm). And the size T2 in the radius direction of the glass bulb where the thickness is lower by t2 is arranged as T1/T2=1-0.77, where T1 is the thickness of the glass bulb, which is also determined in consideration of allowable installation accuracy gap to the outer diameter phiD of the mesh ring at the flange portion. In order to form a deflecting electrode 3 inside the glass bulb 1 with a step at its tip, a metal such as Ni or Cr is vacuum evaporated, when, the step 1a is vacuum evaporated at the same time, and then, they are separated into the deflecting electrode 3 and the vacuum evaporated electrode 3a around the mesh ring 8, by etching or laser processing.

Abstract: PURPOSE:To diagnose securely the operation of an error correcting circuit and to prevent error occurrence, by providing an error pattern register for indicating a prescribed error pattern in each byte, and reading it synchronously with normal data and performing a synthesizing operation. CONSTITUTION:In a storage device MM connected to a CPU, positions of error occurrence are stored, byte by byte, and by a clock from the CPU, normal data DT is applied to one input of an exclusive OR operation circuit EOR. At this time, an address from the device MM is applied to a multiplexer MPX through a presetting circuit PS to change address positions. Then when registers RG1 and RG2 detect an error, a prescribed bit position of the bit pattern of the register RG1 or RG2 is set to 1 to satisfy conditions of AND operation AND, whose output is applied to the multiplexer MPX. The output of this multiplexer MPX is applied to the other input of the circuit EOR to diagnose the operation of the error correcting circuit securely, preventing error occurrence.

Abstract: PROBLEM TO BE SOLVED: To suppress the coarsening of crystal grains in the heat-affected zone of a steel and to improve its toughness by uniformly dispersing fine oxide in which the particle size is specified into a steel at specified dispersion density. SOLUTION: Into a steel, the oxide having <=1 μm particle size is dispersed within the range of 1000 to 100000 pieces/mm<2> dispersion density. The dispersion density is prescribed to the range from 1000 pieces/mm<2> capable of allowing the oxide particles to exist in a state corresponding to the size of the particles of the steel structure, i.e., the state corresponding to about 30 μm to 10000 pieces/mm<2> corresponding to the limit in the case the possibility of aggregation is low in >=1 μm distance between the particles of the oxide. This oxide- dispersed steel is produced by arranging a molten steel in slag consisting of either or both of oxide such as SiO2 , Al2 O3 or Na2 O and fluoride such as CaF2 , supercooling them and crystallizing out the oxide from the molten steel being into a supercooled state.  The supercooled state denotes the state in which the molten soln, is held to the temp. less than the m.p., and as for the supercooling degree, the 1/5 of the m.p. of the material is taken as the maximum value.
