Abstract: PURPOSE:To make even a semiconductor memory containing defective bits useful, by collecting information that whether defective bits in the IC memory are admissible or not and information which minimize an address to be masked. CONSTITUTION:A fail bit map memory 8 performs accessings which are coincident with addresses of an IC memory to be tested 6, and stores defective bits information in a location assigned to defective bits in the memory 6. The bit information is transferred to a CPU1 after a series of tests is completed and displayed. Moreover, the total number of defective bits is counted by a fail bit counter 9 and the primary judgement on the conditions to be possessed by memories whose bits are partially defective, is performed. Then, computations which minimize the total sum of row lines and column lines containing defective bits are performed, and the secondary judgement whether the total sum of lines computated and selected is within an admissible range or not is made. When the memories whose bits are partially defective are within an admissible range, the result is available as mask to ascertain the quality of the memory 6, at the time of test to which the selected line follows as fail information.

Title: Color image forming device
Inventor: OCHIAI TOSHIHIKO
IPC: G03G15/01
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To efficiently perform a fixing process and to output a sharp image by fixing an image under the same conditions as those used for plain paper in the case a transfer material is a monochrome OHP sheet. SOLUTION: In a color OHP sheet, a PET film is coated with resin. For example, in a color data mode, when magenta toner and yellow toner are transferred and fixed to it, light from a projector is transmitted through the resin on the film and the melted and fixed toner, and projected as red on a screen. In this case, it is necessary to mix the magenta toner and yellow toner sufficiently, and a sufficient amount of heat is required to fix them. In the case of a monochrome image, on the other hand, it is not necessary for black toner to transmit light, and an amount of heat required to fix the image is smaller than that required to fix the color image. Therefore, when the color OHP sheet is detected by a transfer front end sensor and the data of an original document is monochrome, fixing is carried out under the same conditions as in the case of image formation on plain paper used as a transfer material.
