Filed: 1981-10-05
Abstract: PURPOSE:To facilitate assembly forming bent supporting pieces at both sides of the rear part of a base each in one body, and inserting collar pins into the supporting pieces and flanks of a disket base in an unextractable state. CONSTITUTION:At both sides of the rear part of a base 1, supporting pieces 29 are bent and formed each in one body, and hinge holes 31 and 32 are perforated in those supporting pieces 29 and both side plates 30 of a disket base 4 to insert collar pins 34 into them.

Title: Error correcting and encoding method
Inventor: KOJIMA YUUICHI
IPC: G06F11/10
Filed: 1982-09-11
Abstract: PURPOSE:To perform a correction for each bit, by adding a check bit to each of information bits distributed in a matrix form for BCH encoding and at the same time generating a parity bit at least to the information and check bits which are arrayed in a single direction. CONSTITUTION:The BCH encoding is carried out by adding the check bits to plural information bits distributed into a matrix form as well as to the plural information bits arrayed in the horizontal and vertical directions. Then a parity of 1 bit (even or odd parity) is added to the information and check bits arrayed in the horizontal and vertical directions. It is possible to use a BCH code having the code length of 255 bit and the information bit length of 239 bit. A check bit is set at 16 bit. The 103 bit is not used among 239 bit of the information bit length, and the unused bit is applied for decision of errors. In such a way, the random and burst errors can be corrected for each bit. Furthermore the error corrections can be reduced.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing and carbonizing iron oxide to produce iron carbide, capable of expanding a bulk gas-selecting range and improving an industrial practicality by adjusting the partial pressure of hydrogen sulfide in a reducing gas and carrying out the reaction at a pressure above the atmospheric pressure. SOLUTION: This method for producing an iron capable comprises reacting the iron oxide such as an iron ore with a reducing gas containing hydrogen and carbon compounds, while sulfur components contained in the reducing gas and/or the iron ore are used. Therein, an active sulfur amount (as) is determined by equation I [PH2 S/PH2 is the ratio of H2 S partial pressure/H2 partial pressure in the reducing gas; (PH2 S/PH2 S)E is the ratio of H2 S partial pressure/H2 partial pressure in the reducing gas, when the reaction of equation II ((s) is a solid state; (g) is a gaseous state) is balanced], and the partial pressure of the hydrogen sulfide is adjusted so as to satisfy follows: as = 1.0 to 2.0, when the reaction temperature in 550-650 deg.C, as = 0.7 to 2.0, when the reaction temperature is 650 deg.C, and as = 0.05-1.0, when the reaction temperature is 650-950 deg.C.  The reducing and carbonizing reactions are simultaneously carried out at the atmospheric pressure to 50 atmospheric pressure or at <=20 atmospheric pressure. The reaction pressure is controlled in a stably ion carbide-producing region in response to the concentration of oxidizing gases in the reducing gas.

IPC: G03F1/84
Filed: 1989-06-23
Abstract: PURPOSE:To easily detect a flaw and to shorten the flaw detection time by allowing only the flaw part to appear as a pattern of a metallic thin film. CONSTITUTION:Two photomasks which have the same pattern to be inspected as to the flaw are used and transfer is carried out by using resist in positive- negative inversion relation. Formed resist patterns 13 and 15 are in complementary relation to each other, so when there is no flaw, the metallic thin film 12 is removed completely by etching. If there are flaws 14 and 16, those flaws 14 and 16 are not in common normally between the two photomasks, so the flaw parts 14 and 16 are patterned with the metallic thin film 12. The flaw parts 14 and 16 can be developed as both white flaws and black flaws by changing the positive and negative states of the resist used for exposure using the photomasks. Consequently, the detection speed of the flaw parts 14 and 16 is increased and the time of the flaw inspection is shortened.
