Title: Cold-rolled steel sheet having excellent glazable characteristic and formability
Inventor: SATOU HIROTAKE
IPC: C23D5/00
Filed: 1982-08-19
Abstract: PURPOSE:To provide a titled inexpensive cold-rolled steel sheet which permits production by continuous casting, contg. a trace amt. of C and a required amt. of O, contg. also Nb except its oxide form at a content of prescribed magnification to the content of C, and the balance consisting substantially of Fe. CONSTITUTION:A titled cold-rolled steel sheet for enamel contains, by wt%, <=0.003% C, and >=0.020% O, contains >=2 times -0.04% Nb (except the Nb existing as an oxide) based on the content of C and consists of the balance Fe and unavoidable impurities. The above-described content of C improves simultaneously the elongation characteristic value of steel and the material quality such as gamma value, and prevents the generation of gaseous CO in the stage of continuous casting. The content of O increases the hydrogen occluding power in the above-described content of C and suppresses the generation of fishscale. Nb is added in order to improve the defect of increasing anisotropy when a billet decreased in C to an ultralow content in the stage of production is cold- rolled to a steel sheet. This cold-rolled steel sheet is characterized by the capability of permitting treatment in a continuous annealing furnace by using particularly a continuous casting slab without subjecting the same to oven annealing.

Abstract: PURPOSE: To effectively carry out a prescribed surface treatment with plasma after removing organic matters effectively, by decomposing the organic matters stuck to the plasma-treating object by oxygen plasma and removing decomposed gas.  
     CONSTITUTION: Oxygen plasma is generated by a well known process using such as electrodeless discharge by microwave, direct current discharge, alternating current discharge or high frequency discharge. On this occasion, the electrodeless discharge by microwave is preferable in view of mass productivity. A plasma-treating object having organic matter stuck thereto is placed in the above-mentioned oxygen plasma and is left as it is for a prescribed time in the range of a prescribed temperature. By this treatment, the organic matters are decomposed and discharged by a pump in gas state. Thus, plasma surface treatment is given to the treating object deprived of the organic matters by the plasma e.g. nitrogen plasma or plasma of gaseous mixture of hydrogen and nitrogen.

Abstract: PURPOSE:To improve the jetting efficiency of ink particles by a method wherein an escape of pressure wave to outside in case of driving of an electrostrictive elements is reduced by increasing the rigidity of an outer wall of conducting passage. CONSTITUTION:For example, a reinforcing plate 21 made of a ceramic is bonded by an adhesive with all over the outer wall surface of conducting passage 4 together with a ceramic heater 20.
