Title: Image processor
Inventor: SEMASA TAKAYOSHI
IPC: H04N1/403
Filed: 1990-02-21
Abstract: PURPOSE:To improve contrast in a transient halftone image area by deciding whether a halftone image area is a true halftone image area or the transient halftone image area, and performing binarization on the area by a dither method after applying level emphasis to the picture element signal level of the transient halftone image area corresponding to the peripheral level of a picture element. CONSTITUTION:A halftone image decision circuit 4 decides whether a remarked picture element X in the halftone image area is the picture element in the true halftone image area or the transient halftone image area based on the maximum value Max and the minimum value Min. A picture element signal emphasis circuit 9 emphasizes the levels (a-d) of the picture elements neighboring in all directions and the level (x) of the remarked picture element X based on a prescribed emphasis coefficient (k). After the level (x) of the remarked picture element in the transient halftone image area is emphasized at L, the binarization by the dither method is applied. Therefore, each picture element of a white or black level can be concentrated in each area in the transient halftone image area, which heightens the contrast in the transient halftone image area as a result.

Title: Water level abnormality detector for steam generator
Inventor: MORIE KAZUHISA
IPC: F22D5/26
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To enable quick detection of abnormality in water level by detecting the temperature of heat sent from an electric heater to examine the abnormality in water level from changes in the detected temperature. SOLUTION: A temperature detector 3 detects temperature above an electric heater 2. The temperature detected does not rise above a fixed value while the detector detects only the temperature of water in a heating water tank 1. But when the electric heater 2 overheats as water vanishes surrounding the electric heater 2, the temperature of heat transmitted by radiation rises above the temperature of water. Therefore, when the temperature detected by the temperature detector 3 is higher (for example, 120 deg.C) than the temperature of the water, abnormality in water level is determined to occur and a controller 5 works to stop the electric energization of the electric heater 2.  As the temperature detector 3 is installed closer to the upper surface of a heat generator 4, the water level abnormality can be detected even if only the top part of the electric heater 2 is exposed from the surface of water. Thus, the detection of the water level abnormality is possible before the water level falls below the position of the electric heater 2.

Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To uniformly stabilize the electric resistance value over the whole surface of a roll and minimize the wrinkling by covering a core material having a necessary strength with a semiconductive seamless tube of a synthetic resin containing resin-coated carbon black. SOLUTION: As the base resin of the seamless tube, polypropylene or epoxy resin is used, and as the core material, a metallic bar or cylinder of a material having a strength necessary for retaining the form of a roll such as stainless steel, aluminum alloy or the like is used. In the covering, the resin solution is added to a water slurry of carbon black little by little with stirring, and the solvent and water are removed by vacuum drying after draining to provide a resin-coated carbon black. This is then mixed with a thermoplastic resin followed by kneading to pellet the mixture, which is then extrusion molded to form a seamless tube, and the tube is fitted onto the core material. Since the change of resistance value accompanied by the increase in mixing quantity of the resin-coated carbon black is moderate, the control is facilitated.  According to this, a roll stabilized in electric resistance in a semiconductor area of 1013-104 Ω.cm can be provided.
