Title: Filthy water turbidity removing device using negative pressure
Inventor: TAMIYA ISHINOBU
IPC: B01D21/24
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To increase the treatment capability of a sedimentation tank due to three-dimensional adsorption removal by filling a chamber encircled with a punching metal and a steel net in a negative pressure generation tank with floating granular negative pressure generating bodies and making a filthy water flow upward from the lower part of the tank in the upper punching metal direction. SOLUTION: A treated water is introduced from a sedimentation tank through an untreated water inlet 1, and a filthy water passing through a reaction tank 3 and a steel net 5 creates a negative pressure zone between granular negative pressure bodies at a flow velocity through a negative pressure body group 6 to absorb suspended solids. The treated water is drained from a treated water outlet 8 through a punching metal 7. The water flow is stopped by closing the untreated water inlet 1 and the water level is lowered to a valve 9 for level adjustment by opening the valve 9. After that, the floating negative pressure bodies 6 brought into contact tightly with the metal 7 are cleaned by friction with the help of a pump impeller 12 passing through a negative pressure body unloading aperture 10 and a valve outlet 11 for solid/water adjustment.  Further the negative pressure bodies 6 are returned to a negative pressure tank through a solid/liquid mixing pipe 15 and are circulated and operated in the negative pressure tank, while sludge is drained through a drain outlet 14 from a ludge reservoir 4. Thus it is possible to prevent the carry-over of the sludge from the sedimentation tank from occurring and increase the treatment capacity of the tank.

Title: Superprecision lapping machine
Inventor: MUTO MASAYUKI
IPC: B24B37/12
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To regulate the amount of the grinding load of a dynamic pressure bearing to a work freely, by supporting the upper and the lower lapping plates on a dynamic pressure bearing soaked in a liquid, and making at least one side of the lapping plates rotatable normally and reversely. SOLUTION: When a ring form frame 10' is soaked in the liquid 13' of a ring form oil tub 11 having a horizontal bottom 12', and the ring form frame 10' is rotated by a driving source M4, the ring form frame 10' is floated up opposing to the load from the lower side, mainly by the resistance of the liquid 13' flowing in to the inside of a cam form recess 9'. When the rotating direction is reversed, the ring form frame 10' is operated to increase the vertical load of an upper lapping plate 2 naturally. Consequently, in the lapping operation, the upper lapping plate 2 and the lower lapping plate 3 are the grinding plates operating perfectly independently, and the relative operations are never generated.

Title: Method and device for producing multigradation character
Inventor: YAMAZAKI NAOMI
IPC: G09G5/28
Filed: 1990-11-22
Abstract: PURPOSE:To enable high speed conversion by making processings for obtaining blend ratio and determining gradation color independently, and storing the calculated blend ratio for re-use. CONSTITUTION:A blend ratio calculation means 13 calculates a ratio of dots in a character area to those for constituting a character as a blend ratio. Next, based on the calculated blend ratio, a blend means 15 determines gradation color by mixing a color specified as a character color and a background color. In this way, since blend ratio calculation and blending are made independently, the blend ratio determined once can be stored in a primary memory means 14 for re-use. Thus time required for calculation of blend ratio can be reduced to output the characters at high speed.

Abstract: PURPOSE:To reduce the adverse effect of an individual difference onto a human sensing characteristic by providing plural compressors eliminating a data component based on the human sensing characteristic and a selector selecting a desired compressor among the compressors to the code. CONSTITUTION:Digital music data are fed to a selector 1 that selects which compressor (1-n) is to be selected among plural compressors 2. As a result, the digital music data are fed to any selected compressor among the compressors 1-n. Each of the compressors 1-n in able to make compression by itself. Thus, in this coder, plural compression methods each is based on a different sensing characteristic are selected and the selector 1 selects one of the compression methods. The data are compressed according to the selected compression method, which generates compression data. Since the data component to be deleted is revised in the case of compression, the method copes with the change in the data component capable of being eliminated depending on each audible sense characteristic, difference from the preference and difference from the reproducing state or the like.

IPC: G02B6/04
Filed: 1990-11-22
Abstract: PURPOSE:To carry out accurate measurement by forming optical fibers aligned and a plate-like element of a shape suited to a ruler into one piece. CONSTITUTION:An illumination light originating from a light source 1 (fluorescent lamp, incandescent lamp) located above a fiber array ruler 7 is emitted to the fiber array ruler 7, and the light emitted to the incident surface of an optical fiber on the top surface of the ruler 7 from above is transmitted downward, then is projected to an area outside the ruler from a projection plane into a light flux 4. In turn, this light flux is directed to a specified point on an object to be measured or a plane to be ruled 3. Subsequently, no shaded part caused by an outside illumination is present and characters on the surface of the object to be measured or the plane to be ruled 3 appear as if they were embossed on the top surface of the fiber array ruler 7 by an optical fiber array 6. As a result, a size can be measured by a reference line (graduations) 5. Thus it is possible to carry out size measurement accurately.
