Title: Regenerating method of filter medium
Inventor: OGINO MASAO
IPC: B01D29/62
Filed: 1983-12-29
Abstract: PURPOSE:To restore a titled filter medium to the original purified state with simple constitution by passing a pulse current between an anodic plate and a cathodic plate with a filter medium in between. CONSTITUTION:An anodic plate 7 is provided in an original water tank 1, and a cathodic plate 8 is provided in a filtrate tank 2. Both electrode plates 7 and 8 are connected to the circuit of a pulse power source. To restore a fatigued filter medium 3, the supply of water to the filter medium 3, the original water tank 1, and the filtrate tank 2 is temporarily stopped, and a pulse current is passed to both electrode plates 7 and 8. Consequently, the solid matter intruded into the filter medium 3 is attracted to the electrode plates 7 and 8, and dissolved into the acid or alkali released from the filter medium 3 or formed. Accordingly, the fatigue of the filter medium 3 is relieved, and the filtration efficiency is conversely increased to the original state. The current is passed for specified hours, and turned off. Then the original water and the filtrate are discharged, and the filtration is again repeated.

Title: Device and method for automatic signal discrimination and recording medium storedwith control program therefor
Inventor: IKEMOTO YOSHIHIKO
IPC: H04N5/46
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide an automatic signal discrimination device that a kind of input video signal is automatically discriminated and a display device by dot display is simply operated. SOLUTION: In a dot display device such as an LDC or a plasma display, it is necessary to display effective pixels of input video signals over the entire screen. Therefore, an effective pixel region and its location of input video signals are detected (Steps S1 and S2). Moreover, a moving image/a still image discrimination is required because the processing methods for processing an operating mode of the display device and expanding and reducing processes of video signals are different in both cases, one case that a moving image such as video signals is to be displayed and another case that a still image such as a personal computer(PC) image is to be displayed. Thus, it is necessary to discriminate whether input video signals are moving image signals or still image signals (Steps S3 to S5).  When it is discriminated that the image is a moving image, a kind of the moving image is discriminated (Steps S6 to S12). When it is discriminated that the image is a still image, a kind of the still image is discriminated (Steps S13 to S17).

Abstract: PURPOSE:To reduce the cost required for the movement of a lining material in a pipe, by preliminarily receiving a passing wire for pulling back an object in the housing part provided to the object and reducing the resistance due to the passing wire to a large extent. CONSTITUTION:Compressed gas is supplied in a branch pipe 2 by a compressor 8b, and an object 4 and a lining material 9 are moved through the branch pipe 2 by the pressing action of the lining material 9 due to the compressed gas. A passing wire 3 is drawn out from a housing part 4a with the movement of the object 4 in the pipe 2, and the object 4 and the lining material 9 are sent under pressure until the passing wire 3 is extended. After the supply of the compressed gas is stopped, the passing wire 3 is pulled from the outside of the branch pipe 2 by a holder 6 to pull back the object 4 and, at the same time, the lining material 9 is forcibly flowed by the object 4 to coat the inner surface of the branch pipe 2. By this method, lining treatment is applied to the branch pipe 2 over the total length thereof.

Title: Color detection for coordinates analyzing machine
Inventor: TOYAMA AKIO
IPC: G01J3/46
Filed: 1986-10-17
Abstract: PURPOSE:To detect color at a colored portion at a high accuracy, by a method wherein scattered lights from a colored portion of a drawing are admitted into a color sensor while regular reflected lights are blocked and color at the colored portion is detected with the color sensor. CONSTITUTION:A color sensor 34 is arranged at such a position that scattered lights enter when light is projected to a colored drawing 42 on a table 12 and reflected lights thereof are admitted into the color sensor 34 to detect the color of the drawing. When any regular reflected light enters the color sensor 34, a power spectrum of the light gives a higher level A1 of amplitude S of a color signal based on the degree of noise N (namely, regular reflected light). The power spectrum of the light reaching the color sensor is composed of scattered lights with no regular reflected light (noise) contained. This lowers the level A2 of the amplitude of the color signal thereby enabling positive color discrimination with a greater value S/A2.

IPC: G06T11/20
Filed: 1994-09-14
Abstract: PURPOSE: To prepare a high-quality bit map font with no drop out. CONSTITUTION: An edge data generating part 1 prepares horizontal edge data and simultaneously prepares vertical edge data as well. These edge data are stored in an edge data storage part 2. Next, a scan converting part 3 performs horizontal scan conversion and performs vertical scan conversion as well. Then, a run writing part 4 writes both horizontal and vertical runs in a storage area. In this case, when the drop out is generated in the horizontal run, the drop out is canceled by the vertical run. On the other hand, when the drop out is generated in the vertical run, the drop out is canceled by the horizontal run. As a result, the drop out is canceled by both the horizontal and vertical runs.

Abstract: PURPOSE:To provide a pressure sensor capable of outputting a stable detection signal having no temperature dependency even when the ambient temperature is changed. CONSTITUTION:A piezoelectric element 20 displacing a diaphragm 13 via a pressure receiving rod 15 and outputting a voltage signal in response to pressure is provided in a casing 11.
