Further, the ferritic stainless steel has a surface oxide layer in which Mn is concentrated to a proportion of two or more times as compared with the steel as basis material. It is preferable to control V content in this ferritic stainless steel to >=0.1%. When a steel plate or steel tube, having this composition, is heated to 900-1100 deg.C in an atmosphere of >=10vol.% oxygen concentration to undergo annealing, workability and oxidation resistance can be improved. The annealed steel plate or steel tube can be served as product without aftertreatment, such as acid pickling and polishing.  This steel is excellent in sulfuric acid resistance and high temp. oxidation characteristic as well as in intergranular corrosion resistance, high-frequency tube making property, and high temp. strength characteristic.

Title: Spatial modulating element
Inventor: AKIYAMA KOJI
IPC: G02F1/1368
Filed: 1989-07-19
Abstract: PURPOSE:To enable threshold processing for multi-input by providing a liquid crystal tank, a part which has photoconductivity, and field-effect transistors(TFT), irradiating the photoconductive part with light, and modulating the intensity of an electric field applied to the liquid crystal tank. CONSTITUTION:This element consists of the TFTs 1 and 2, liquid crystal tank(CLC), and photoconductive tank(CPC). Then when the TFT1 is applied with VG at its gate electrode and then turns on to charge the CPC, the VG is reduced to turn off the TFT1, the gate voltage of the TFT2 is nearly equal to VF, and the TFT2 conducts to apply an AC voltage V to the CLC. Then the CPC is irradiated with light and when the light intensity becomes large enough to reduce the resistivity sufficiently, charges accumulated in the CPC are neutralized and the gate voltage of the TFT2 drops. Consequently, the TFT2 turns off and the AC voltage V is not applied to the CLC and more. Consequently, the voltage applied to the CLC can be controlled by the light irradiation and the threshold processing for multi-input is enabled.

Since the DC ammeter 5 is earthed via a variable DC voltage generating device 4, a current flows corresponding to the difference in potential between the voltage generating device 4 and the electrode 7. Accordingly, a value obtained when the indication of the ammeter 5 turns zero with the voltage of the voltage generating device 4 raised in the potential of the electrode 7.
