Patent JP-H01137282-A (JP)
Title: Electrophotographic device
Inventor: MIWA KIYOHITO
IPC: G03G21/00
Filed: 1987-11-25
Abstract: PURPOSE:To prevent a fact that the surface of a photosensitive body is flawed and a service life of the photosensitive body is shortened thereby or a cleaning failure is generated by providing a toner consisting of a superconductive material and a developing means for developing an electrostatic latent image to a toner image by the toner. CONSTITUTION:When an operation of an electrophotographic device is started, a photosensitive body 11 starts to rotate in the direction as indicated with an arrow 15, the surface of the photosensitive body 11 is electrified uniformly by an electrifier 12, and thereafter, an electrostatic latent image is formed by an exposing device 13. After the transfer, a superconductive toner which has remained behind on the surface of the photosensitive body 11 is separated from the photosensitive body 11, since what is called a Meissner effect occurs by a magnetic field generated from an electromagnet 20 for cleaning. When a current is supplied to the electromagnet 20, the influence of the magnetic field is exerted on each process of development and transfer, as well as there is the possibility that disorder of an image is generated, therefore, magnetic shielding is performed to the periphery of the electromagnet 20. After cleaning is executed, the surface of the photosensitive body 11 is destaticized by a destaticizing lamp 19. In such a way, the toner can be eliminated without applying mechanical force to the photosensitive body and without flawing the surface.

Title: Magneto-resistance effect type head
Inventor: SASAKI YUSHI
IPC: G11B5/39
Filed: 1988-11-24
Abstract: PURPOSE:To prevent the leakage of the sense current of a magnet-resistance element to a recording medium and deterioration of the characteristics of the element by providing an insulating film so that the magneto-resistance element cannot crop out on the surface of a magneto-resistive type magnetic head facing the recording medium. CONSTITUTION:An insulating film 17 is provided so that a magneto-resistance element 11 cannot crops out on the surface 16 of a magneto-resistance type magnetic head facing a recording medium. The width of the element is set to (w) in a wafer processing stage and a grinding process is performed on the magnetic head in the next slider processing stage so as to form the film 17 having a width (t) to the surface 16. Therefore, even when the magnetic head is brought into contact with the recording medium, the sense current of the element 11 does not leak to the recording medium and occurrence of such a case that the voltage across both ends of the element 11 instantaneously drops or data recorded on the recording medium are destroyed by a leakage current can be prevented.

Filed: 1990-10-31
Abstract: PURPOSE:To vertically lift a lift platform by detecting an angle at which a telescopic boom body is elevated relating to a car body, supplying a fixed amount of pressure oil to an extending means by each signal of a detection value of this elevation angle, and vertically holding a locus of a point end of the telescopic boom body. CONSTITUTION:When pressure oil is supplied to cylinders 9, 18, 86, an elevation angle is increased in a telescopic boom body 13 and also extending an intermediate boom 10 and a point boom 11 to lengthen the telescopic boom body 13. Now in order to vertically place a rising locus S of a pin 15, an extension N of the telescopic boom body 13 to reach 15-2 from 15-3 must be larger than an extension M when the telescopic boom body 13 reaches 15-2 from 15-1. Consequently, the elevation angle of the telescopic boom body 13 is detected by an angle detecting means 50, and a pulse signal is fed in accordance with a detection value of this elevation angle. By this signal, a fixed amount of pressure oil is supplied to the telescopic moving hydraulic cylinder 86 simultaneously supplying a fixed amount of the pressure oil to also the elevation cylinders 9, 18 to control the telescopic boom body 13 so that its extension properly follows up relating to the elevation angle of the telescopic boom body 13.

Title: Highly accurate resist patterning method on substrate having difference in level
Inventor: HIEDA KATSUHIKO
IPC: H01L21/027
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To improve reliability by eliminating a CD(critical dimension) control error. SOLUTION: As a highly accurate resist patterning method on a substrate having a difference in a level, the difference in the level of a base is flattened by forming flattening film 21 on the substrate 1 having the difference in the level, and reflection preventive film 22 is formed on it so as to be flat, and the highly accurate patterning of a resist 23 is executed on it. Thus, the appearance of a standing wave effect is stopped, and the CD control error caused by the standing wave effect is eliminated. In the case that the flattening film 21 consists of hydrogen silosesquioxane, it is similarly removed by alkali developer as the resist or the like. Thus, a selection ratio for SiO2 film, polycrystal silicon and SiN film is set to be large, and the CD control error of a base pattern caused by over-etching at the time of removing the flattening film is eliminated.
