The present invention provides a ferritic stainless steel casting and a sheet thereof excellent in deep drawability, punch stretchability and ridging resistance and a method for producing the casting and the sheet. In the present invention, a chemical composition is controlled so that the amounts of C, N, Si, Mn, P and Ti may be reduced to the utmost for securing high workability and, on the basis of the chemical composition, the roping and ridging of a steel sheet product is reduced by adding Mg, thus dispersing Mg containing oxides that accelerate the formation of nuclei for solidification and, resultantly, suppressing the development of coarse columnar crystals in a casting. The present invention is characterized in that the average composition of the Mg containing oxides dispersing in a casting satisfies the following expressions and , 17.4(Al2O3)+3.9(MgO)+0.3(MgAl2O4)+18.7(CaO)≦500 , (Al2O3)+(MgO)+(MgAl2O4)+(CaO)≧95 .

摘要:
Inspection is performed without applying an excessive pressure to an inspection object to thereby resolve inspection failure caused by excessive pressure application. An electrical connection device electrically connects a signal wiring formed on a wiring board to an electrode part of the inspection object. A contact is provided which electrically connects together the electrode part of the inspection object and the signal wiring of the wiring board. The contact includes: an electrode abutting part that abuts the electrode part located on a lower portion of the inspection object, a wiring abutting part that abuts the signal wiring, an elastic body support part that fits with the elastic body to elastically support the entire contact, and a release lever part that is pressed to thereby rotate the entire contact whereby the abutting between the electrode part of the inspection object and the electrode abutting part is released. The release lever part is pressed down and released by the cover that moves up and down.

摘要:
An image reading apparatus for converting an image on a document having a white/black text area into a display signal. An image reader scans pixels forming the image to produce a read signal having a level corresponding to the brightness density of each of the scanned pixels. The read image is compared with a dither matrix data signal and converted into a dither converted signal. The read image is also compared with a threshold value and converted into a binary signal having a first level representing a white pixel and a second level representing a black pixel. A discrimination circuit receives the binary signal for producing a detection signal when the white/black text area is scanned. Upon occurrence of the detection signal, the dither converted signal is mixed with the binary signal to form the display signal.
