Title: Floating point data expression format converting system
Inventor: NAKAMURA TOSHIHIKO
IPC: G06F7/76
Filed: 1989-11-08
Abstract: PURPOSE:To perform a conversion processing in a short time by using an adder for the conversion processing of a data expression format. CONSTITUTION:At the time of instructing the expression format conversion, an exponential part shifter 10 performs the processing based on a shift variable signal C2 from an operation preprocessing means 8 and outputs the output to an exponential part processing means 12 as an exponential part E2 during the operation. A maintissa part shifter 5 shifts the fixed-point part selected by a selector 3 based on a shift variable signal C1 sent from the operation preprocessing means 8 and outputs the result to an adding means 6. The adding means 6 adds the output of the selector and the output of a selector 4 (numerical value '0' is inputted at the time of instructing the expression format conversion) and generates and outputs an addition result C7 and information C6 accompanied with the result which is required for normalization after operation. Thus, the processing time is shortened since the conversion processing of the data expression format is easily realized with only one instruction.

Title: Image forming device
Inventor: OKANO KEIJI
IPC: G03G21/00
Filed: 1987-11-19
Abstract: PURPOSE:To obtain an image of good quality which has neither a decrease in image density nor an irregular image by holding a sleeve which is arranged in a developing device at an interval with the surface of an image carrier through spacer rolls and positioning the spacer rolls within a range of cleaning width. CONSTITUTION:The spacer rolls 41a and 42a arranged on both ends of the developing sleeve 4a arranged in the developing device 4 maintains the interval of the sleeve with the surface of the image carrier 1 and the spacer rolls 41a and 42a are positioned in a cleaning area. Consequently, even if a seal material at a blade end does not operate sufficiently to cause a leak of toner, the rolls 41a and 42a do not move onto the leaking toner to cake the toner, so the interval between the image carrier 1 and developing sleeve 4a is held constant and the relative traveling between the both never becomes irregular, so an image of good quality is obtained without generating any decrease in image density nor any irregular image.

Title: Non-water treatment for forming pattern on high temperature superconductor thin film
Inventor: JIEEMUSU EMU MAIROZUNIKU
IPC: H01L39/24
Filed: 1990-10-30
Abstract: PURPOSE: To enable depositing of various metals in a wide range to a thin film surface by forming a first photoresist layer, into which water does not penetrate, on the surface of a material deteriorated by water, forming a second photoresist layer for treating on the first layer using water as a base, and removing part of both the layers and treating uncovered portion of the surface. CONSTITUTION: On the surface of a thin film 10a consisting of a material deteriorated by water, a first layer 12 composed of a first photoresist material not penetrated by water is formed, a second layer 14 is formed on the first layer 12, and this second layer is constituted with an ordinary water base photoresist. Then, the layers 12 and 14 are treated, and a desired portion on the surface 10a is partially removed so as to make a desired portion in an uncovered state. In this case, the treatment of the photoresist layer 14 by a solution, based on water will not give adverse effects on a surface 10a because of a non-aqueous penetrating photoresist layer 12 being interposed. Next, the exposed portion of the surface 10a will have a pattern in the predetermined portion formed by using layers 12, 14 as treatment mask. Finally, the layers 12, 14 are removed by a non-aqueous solvent.  In this way, an effective treatment technique for sticking metals to the surface of a thin film can be obtained at a low cost.
