Title: Permanent magnet and its manufacture
Inventor: AKIOKA KOJI
IPC: C22C38/00
Filed: 1988-06-20
Abstract: PURPOSE:To produce an R-TM-B system permanent magnet of thin thickness, high performance and low cost by making the specific quantity of a rare earth rich phase which is a non-magnetic phase and specifying its true coercive force on the permanent magnet which makes material main constituents of a rare earth element, a transition metal element and a group IIIb element. CONSTITUTION:R-M-X of R (R is a kind of rare earth containing Y), TM (TM is a kind of elements of the transition metals including group IIb) and X (X is a kind of a IIIb group) is made a material base constituent. The constituents are melted to cast and hot working of a casting ingot is performed at 500 deg.C or higher. When the liquid phase of an R-rich phase which is non-magnetic substance is eliminated to enrich a magnetic phase and mechanical orientation and magnetic anisotropy are given, practical coercive force of 5KOe or more can be obtained although non-magnetic phase and the R-rich phase are 8% or less of the whole even if average thickness of the R-rich of grain boundaries is 2mum or less, excluding the part of the multiplex points.

Title: Manufacture of polycarbonate sheet
Inventor: MIYAUCHI MASAYOSHI
IPC: B29C48/305
Filed: 1992-06-11
Abstract: PURPOSE:To make it possible to stably produce roughened sheet excellent in slip characteristics at a low cost by a method wherein sheet, the thickness at both the ends of which are thicker than that at the remaining part, is extruded and pinched with cooling rolls so as to roughen one side of the sheet excluding both ends thereof. CONSTITUTION:The sheet is manufactured by taking off powder-containing polycarbonate sheet 2, which is melted and extruded from a T-die lip 2, under the condition being pinched by cooling rolls 3-5 with take-off rolls 6. In this case, the thickness at both the ends 2' of the sheet is made thicker than that at the part 2'' excluding both the ends of the sheet. When the sheet is pinched by the cooling rolls 3 and 4, both the ends 2' only pinched and one side of the sheet part 2'' comes into contact with the cooling roll 4, while the other side does not come into contact with the cooling roll 3. In addition, the thickness at both the ends 2' is made thicker by 0.1mm or more than that at the sheet part 2''. Thus, uniform and roughened sheet can be produced.

Title: Co2 gas laser device
Inventor: TAKAHASHI HIDEOMI
IPC: H01S3/038
Filed: 1988-06-22
Abstract: PURPOSE:To improve uniformity of glow discharge for ignition and to enhance laser output, by forming divided electrodes of a cathode into SIGMA shape while providing a fine projection at the center thereof. CONSTITUTION:Glow discharge caused by applying a high voltage to a cathode 5 gives energy by which CO2 molecules are excited and laser light 12 is outputted from an optical resonator 8a. If a high voltage is applied to the cathode 5 under a reduced gas pressure, glow discharge is caused initially at the tip end of each fine projection 13 and as the gas pressure as well as the voltage is increased the glow discharge is extended quickly from the fine projection 13 to a whole SIGMA-shaped cathode pins. Then, when current of the glow discharge 11 is decreased, negative glow is translated from a part 5a to the fine projection 13 through a part 5b, Thus, discharge is always held at the fine projection 13. In this manner, uniformity of discharge is improved and enhanced laser output can be obtained.

Abstract: PROBLEM TO BE SOLVED: To exactly match the optical axis of a photographic lens with an object intended by a photographer, even in the case of proximity photographing by arranging the photographing lens so that it optical axis almost coincides with the central axis of a liquid crystal screen. SOLUTION: A photographic lens 3 is arranged on the front face of a camera body 2 and at its central part, a liquid crystal monitor 4 is arranged on the back of the camera body 2, and an optical axis of the photographic lens 3 becomes a normal which passes through the center of the liquid crystal monitor 4. That is, the optical axis 5 is coincident with the central axis of the liquid crystal monitor 4. In case of photographing, an image fetched from the photographic lens 3 is converted into an electric signal by a CCD and the image is projected on the liquid crystal monitor 4 in real time. Namely, the liquid crystal monitor 4 plays the role of a liquid crystal view finder. Therefore, a photographer determines the size or range of the image, while watching the liquid crystal monitor 4 and performs photographing by pressing a release button 1.  In this case, an object comes on the extension line of the sight of the photographer.

Title: Controller for image forming device
Inventor: IDE FUMITO
IPC: G03G15/00
Filed: 1987-06-19
Abstract: PURPOSE:To eliminate malfunction by resetting an output mode periodically while data is outputted through a port which is set in the output mode. CONSTITUTION:Input/output ports 35 and 42 are used as input or output ports according to the setting of port mode data to a port usage setting register by a microcomputer 31. A ROM 43 is stored with a subroutine which redefines the usage of a port when data is inputted through the port set as an input port in addition to a main program and an initial setting program for copying operation, and the contents of the usage setting register of the port 35 are reset to the input mode right before the input data is read in the computer 31 through the port 35. Even if the contents of the usage setting register are destroyed before the input port input subroutine is executed, the input data from the port 35 is invariably set for the input port and then inputted. Thus, wrong data is prevented from being inputted to the computer 31.

Since the carrier generating material is incorporated into said layer in the form of grains, the memory phenomenon is lessened nd the residual potential is stabilized. Since the amine is specified to the molar number of <=1 times the molar number of the carrier generating material, the substantial dissolution of the carrier generating material by the amine in the stage of coating and forming the carrier generating layer is obviated and said material can be held dispersd into the coating liquid. As a result, the coating in the dispersed state is made possible, by which the crystallinity of the coating layer is improved, the change of absorption spectra is obviated and the photosensitivity is improved.
