Title: Image forming device
Inventor: ISHIWATARI KAZUHIKO
IPC: G03G15/00
Filed: 1994-08-01
Abstract: PURPOSE:To prevent toner powder dropping from a carrying device for carrying a sheet material on which a toner image has been transferred in a transfer part to a fixing part from infiltrating into a resupply path. CONSTITUTION:Plural cover members 40 respectively individually covering the aperture parts 38 and 39 of an upper guiding plate 29A forming the resupply path 29 are set on the guiding plate 29A. The cover member 40 is turnably attached in an up-and-down direction centering around a supporting shaft 41 at its one end with respect to the guiding plate 29A. Since a leg part 42 at the other end of the member 40 abuts on the upper surface of a lower guiding plate 29B outside a paper passing area, the member 40 is ordinarily positioned above a specified height from the upper surface of the guiding plate 29A.

Title: Production of grain-oriented silicon steel sheet having superior blankability
Inventor: NISHIIKE UJIHIRO
IPC: H01F1/16
Filed: 1989-08-03
Abstract: PURPOSE:To produce a grain-oriented silicon steel sheet excellent in magnetic properties and blanking workability by subjecting a silicon steel sheet formed into the final sheet thickness by means of cold rolling to primary recrystallization annealing which doubles as decarburization, finish-annealing the sheet after application of a separation agent at annealing composed principally of MgO, performing pickling, and then grinding the surface. CONSTITUTION:A slab of a high silicon steel containing 2-4.5wt.% Si is hot-rolled, and the resulting plate stock is cold-rolled once or cold-rolled twice or more while being process- annealed between the cold rolling stages so as to be formed into a silicon steel sheet of 0.15-0.35mm final sheet thickness. Subsequently, after the steel sheet is subjected to primary recrystallization annealing which doubles as decarburization in a high temp. and wet oxygen atmosphere, a separation agent at annealing composed principally of MgO is applied to the surface to carry out finish annealing and the surface is subjected to pickling treatment for a short time by means of an aqueous solution of hydrochloric acid, sulfuric acid, etc., and further, grinding is applied to the surface by means of a grinding roll composed of elastic material or a grinding brush, by which a forsterite coating can be completely removed without applying strain to the matrix of the silicon steel sheet. By this method, the grain- oriented silicon steel sheet excellent in blankability can be produced.

Abstract: PURPOSE:To manufacture a molding too, whose accuracy is favorable, in a suort period of time and inexpensively, by transferring and sticking rubber or synttetic resin to a mold surface by pressing a split mold forming a rubber or synthetic resin layer by applying a mold release agent to the outside of the master of a molded article. CONSTITUTION:A master 1 is put on a rest 6 and a parting plate 7 is arranged on the circumference of a master. After a mold release agent has been applied to the surface of the master 1 and parting plate 7, epoxy resin 8 is applied to the surface of them thick and one side split mold 2 is pressed against the master before the surface does not cure. At a stage wherein the resin 8 has cured, the rest 6 and parting plate 7 are inverted, the rest 6 and parting plate 7 are removed, to both of which the mold release agent is applied, the epoxy resin 8 is applied thick and the other side split mold 3 is pressed against the master before the surface does not cure. As the resin 8 is stuck to a split mold side when the same is cured, a molding tool 9 for a model is completed when both split molds 2, 3 ar removed.

Abstract: PURPOSE:To load plural types of standard cassette tapes by using a cassette holding mechanism which discriminates the form of cassette put into a cassette box and can control the distance between the supply and take-up reels in response to the result of said discrimination of the cassette form. CONSTITUTION:When a small cassette 25, for example, is put into a cassette box of a cassette holding mechanism set on the main body of a recording/ reproducing device 1, the form of the cassette 25 is detected and tape guides 16a-16c are moved up to the positions shown by the broken lines by a controller (not shown here) before the cassette 25 is set at a fixed position. Then the cassette tape is loaded. The opening part 28 of the cassette 25 is smaller than a regular size and therefore the tape guides 17a, 17b, 18b and 18c and a lead-out guide 21 are put into the opening 28 when the cassette 25 is loaded to the device 1.

Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration in a CNR characteristic and to form a large capacity magneto-optical recording medium by making the total of a phase difference (α) of diffraction light due to a substrate and the phase difference (β) due to layer constitution on a transparent substrate to be an opposite code to the phase difference (γ) due to interference between the diffraction lights from a groove part and an inter- groove part. SOLUTION: When a spot size (s) is smaller than a groove part width Wc, since the diffraction light from the inter-groove part isn't generated, the phase difference doesn't occur, and tracking hardly be performed, and the spot size (s) is made larger than the groove part Wc. When recording is performed on the groove part, the phase difference (γ) becomes a negative value, and when the recording is performed on the inter-groove part, the phase difference becomes a positive value. Then, in recording on the groove, the code of α+β is made positive, and in recording on the inter-groove, it is made negative.  In a four layer structure of a magneto-optical medium, when film thicknesses of a protection layer, a recording layer and an interference layer are defined respectively d1, d2 and d3, and a wavelength in air of reproducing light is (λ), the relation among them is selected preferably within the range of λ/6>=d1>=λ/12, λ/18>=d2>=λ/27 and λ/12>=d3>=60.

Title: Photosensitive body, electrophotographic device provided with the same and process cartridge attachable to/ detachable from the device
Inventor: YOSHIHARA YOSHIYUKI
IPC: G03G21/16
Filed: 1992-07-28
Abstract: PURPOSE:To obtain a process cartridge which suppresses the vibration of a photosensitive body to reduce charging sounds and prevents the uneveness of the cycle by setting the weight per unit volume of the photosensitive body to a specific value or above. CONSTITUTION:With respect to the voltage applied to a core bar 4a of an electrifying roll 4 by a power source 25, the oscillating voltage where an AC voltage is superposed on a DC voltage is preferable. The charging sound generating mechanism generated between an electrifying member and an electrophotographic sensitive body by applying the oscillating voltage is considered as the elastic oscillation of the photosensitive body due to the electrifying member. Consequently, it is thought that the oscillation absorbing effect is produced by adding the weight to the photosensitive body. In consideration of this phenomenon and the actual hearing effect, the weight to the overall volume (including a driving transmission part and a bearing part) of the photosensitive body is >=0.65g/cm<3> preferably. Further, it is >=0.80g/cm<3> preferably for the purpose of more stably obtaining the muting effect.

Abstract: PURPOSE:To generate the same effect as the case where the diameter of an aperture section is increased substantially and reduce lens focussing and then improve focussing characteristics by properly selecting the regression distance of an opposed electrode plate and the shape of an aperture formed on the said opposed electrode plate. CONSTITUTION:An aperture 114 through which the central beam passes and aperture 113 and 113' through which an outside beam passes or an aperture 124 through which the central beam passes and apertures 123 and 123' through which the outside beam passes are provided on a pole plate 112 or 122 in a line, respectively.

When the outside apertures 113, 113', and 123' and the central apertures 114 and 124 are set to the same shapes and dimensions, the lens focussing of a principal lens formed outside in the horizontal direction is increased. As a result, the horizontal diameter of the outside aperture is larger than that of the central aperture and the strength of focussing in both the horizontal and vertical directions can be equalized.
