Title: Recording method
Inventor: TARUMI NORIYOSHI
IPC: G03G15/16
Filed: 1982-12-31
Abstract: PURPOSE:To prevent the reduction of resolution of a toner image and to transfer the toner image with a high transfer ratio by transferring the 2nd toner image after the 1st toner image transferred to an intermediate transfer body has been turned to the state having adhesiveness. CONSTITUTION:When three color images are formed on an intermediate transfer belt 11, a feed roller 18 is actuated and copying paper 20 is carried to a transfer fixing part 14. When the copying paper 20 approaches the transfer fixing part 14, a press contact roll 15 is energized from a virtual line position to a solid line position and both the intermediate transfer belt 11 and copying paper 20 are put between the press contact roll 15 and a fixing roll 13. Since heater lamps 16 are built in the respective rolls 13, 15, the intermediate transfer belt 11 and the copying paper 20 are heated up to the sufficiently high temperature by the radiant heat of the roll and the three color toner images on the belt 11 are simultaneously transferred on the copying paper 20 and simultaneously fixed. Since sufficient adhesion is provided to the 1st toner image by heating the toner image by a heater 24 after tranferring and then the succeeding toner image is transferred on the intermediate copying belt 11, the 2nd toner image is rigidly held by the adhesion of the 1st toner image and overlapped transfer property is remarkably improved.

Title: Production of magnetic recording medium
Inventor: YANO AKIRA
IPC: G11B5/84
Filed: 1987-09-18
Abstract: PURPOSE:To decrease the gaps to be formed to a protective film so that excellent corrosion resistance is obtd. by forming the protective layer while cooling a nonmagnetic substrate to the temp. lower than ordinary temp. and maintaining the surface of a magnetic recording layer at a low temp. at the time of forming the protective layer on the magnetic recording layer. CONSTITUTION:The critical diameter at which the island-shaped particles 3 formed on the magnetic recording layer 1 attain stability depends on the surface diffusion energy which each one piece of the particles possesses. The surface 1 of the magnetic recording layer is, thereupon, maintained at the low temp. by cooling the substrate, by which the surface diffusion energy of the particles is decreased and the island-shaped particles 3 are stabilized even at the small particle size, although small unclei 2 are formed. As a result, the many small island-shaped particles 3 are formed and a continuous film 4 is formed by growing of these particles and therefore, the gaps 5 between the island-shaped particles 3 are decreased and the film densely compacted with the small island- shaped particles 3 is formed. The protective film which fluctuates less in the film thickness or film density and exhibits the high corrosion resistance is thereby formed.

The reduction of the work roll gap by acting a rolling down device during rolling of the annular body is also possible and in such a case, the annular body is rolled successively for more than one round after the rolling down device is stopped. The sectional size of the rolled stock is thus uniformized.

Title: Method for reducing radiation noise
Inventor: KOBAYASHI SATOSHI
IPC: G01R31/28
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce a designing time or electronic components for countermeasure for noise by setting an oscillating frequency of an oscillator to a frequency without respect to integer magnification, thereby simply decreasing a radiation noise level. SOLUTION: When a semiconductor tester is operated, noise is radiated from a main frame 1 or connecting cable 3. At this time, when oscillating frequencies f1 to fn of respective units are set to a frequency irrespective of m times or 1/m times (m is integer), radiation noise is not duplicated in harmonic wave f0 of lower order of the respective oscillating frequencies f1 to fn . Generally, the larger the order of the harmonic wave f0 becomes, the more its radiation level is attenuated. Accordingly, even if the noise is superposed in harmonic wave f0 of higher order, it is radiated at a lower level. Therefore, the level of the radiating noise in the harmonic wave f0 is lowered, and a designing time or electronic components for countermeasure for the noise can be decreased.

In other words, the interruption signals of the asynchronous outputs are temporarily held by the means 10-1 - 10-n, and an interruption signals is newly produced. Thus both the held interruption signals and the new one area all given to the CPU 12 at one time. As a result, a multiple interruption state which causes a software bug of the CPU 12 is regenerated and the software can be tested satisfactorily and with high efficiency.
