Title: Electrifying device and image forming device
Inventor: KASHIWA TAKAAKI
IPC: G03G15/02
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent an image from being deteriorated caused by the sticking of magnetic grains constituting a contact electrifying member to a photoreceptor. SOLUTION: The contact electrifying member 100 is constituted of a multi- pole magnetic substance 102 and a magnetic brush layer 101 consisting of magnetic powder. By impressing a voltage on the electrifying member 100, the photoreceptor 104 is electrified through the layer 101. When the photoreceptor 104 is electrified, the electrifying member 100 and the photoreceptor 104 are rotated in a direction shown by an arrow. The magnetic powder is stuck to the photoreceptor 104 from the electrifying member 100 near both end parts of the electrifying member 100. Then, auxiliary electrodes 105 are arranged at both ends of the electrifying member 100 and the voltage is impressed on it. Thus, the magnetic powder is electrostatically prevented from being stuck to the photoreceptor 104.  Besides, the magnetic powder between both electrodes 105 and 105 is mechanically prevented from being moved to the outside.

Abstract: PURPOSE:To transport a steel sheet without slight meandering by forcively pressing the steel sheet in between with a driving roll via a spring together with supporting a press roll adjustably in a spacing with a driving roll via a spacing regulating stopper. CONSTITUTION:A bolt 23b is moved upward and downward with respect to a nut 23a and thereafter, a shaft 27 is lowered by rotationally operating a handle 29 to have a moving frame 22 supported by the bolt 23b of the spacing regulating stopper 23. At this time, the spacing between both rolls 31 and 32 is so adjusted by utilizing a spacing gage that the set size uniform on the right and the left is attained. The handle 29 is thereafter released and is retreated upward so as not to come into contact with a thrust bearing 30 and thereafter, a tubular member 26 is rotationally operated via its operating section 26a and is so adjusted that the force of a spring 28 to energize a moving frame 22 is made uniform on the right and the left. Consequently, the press roll 32 is lifted by overcoming the energizing force of the spring 28 even if the thickness of the steel sheet changes. The press roll is thus automatically adjusted and the meandering of the steel sheet is prevented.

Abstract: PURPOSE:To shorten a time necessary for the processing of checking recording which is performed just after recording by providing a means for fetching a read signal by a magnetic head and a means for performing the decision of checking recording based on the envelope signal of the fetched read signal. CONSTITUTION:After the signals which respectively pass gate circuits 24A and 24B out of the read signals by the magnetic heads 11A and 11B are amplified in an amplification circuit 23, they are given to an envelope detection circuit 25. The envelope detection circuit 25 detects the envelope of the read signals by the magnetic heads 11A and 11B and converts a voltage signal in accordance with the envelope into an eight bits of digital signal so as to input it in a controller 10. The controller 10 performs the decision processing of checking recording based on the inputted envelope detection signal. When the envelope detection signal exceeds a specified level, the controller 10 decides that recording is correct and completes checking recording with respect to two tracks in an extremely short time. Thus, the interval of consecutive photographing can be shortened by a time shortened in checking recording.

Title: Manufacture of semiconductor device
Inventor: TAKAO YUKIHIRO
IPC: H01L21/31
Filed: 1993-06-15
Abstract: PURPOSE:To reduce the amount of irregularities by reducing the amount of projection of a field oxide film by forming a groove in a semiconductor layer existing in a region wherein a field oxide film is formed and by forming a filed oxide film by selectively oxidizing the semiconductor layer thereafter. CONSTITUTION:A groove 17 is formed in an isolation region of a semiconductor layer 11 wherein an insulation film 12 and an oxide prevention film 13 are formed. When wet oxidation is performed for a surface of the groove 17 of the semiconductor layer 11 through arm opening 16, a field oxide film 18 is formed in the isolation region. In the process, the field oxide film 18 is also formed above the groove 17; however, since most of it is formed within the groove 17, the amount of the field oxide film projecting from a surface of the semiconductor layer 11 is extremely few. Therefore, even if photoresist is applied for patterning the field oxide film 18 and a film formed on the semiconductor layer 11, the thickness of the photoresist is approximately uniform. Accordingly, focus margin of a stepper during exposure increases and pattern accuracy also improves.

Abstract: PURPOSE:To separately measure a leakage component caused by a residual stress of an element-isolation oxide film by a method wherein a MOS transistor which has been formed between a diffusion layer constituting a p-n junction and an electrode-part diffusion layer is measured by opening and closing the transistor and its difference is found. CONSTITUTION:MOS transistors 6, 7 are formed between an n<+> diffusion layer 2 and an electrode part 2a as objects to be measured; leakage currents when they are opened and closed are measured; a difference between both is found. That is to say, when the transistors are opened, a connection part 5a and its peripheral part are connected electrically to the n<+> diffusion layer 2. As a result, it is possible to measure a sum of a p-n junction leakage component caused by a residual stress of an element-isolation oxide film 3 and the p-n junction leakage component caused by an influence at the connection part 5a and its peripheral part. When the transistors are closed, it is possible to measure only the p-n junction leakage component caused by the influence of the connection part 5a and its peripheral part. Thereby, it is possible to separately measure a leakage component caused by a stress of the element-isolation oxide film.
