Abstract: Water softening system includes water softening tank, neutralization tank, electrolysis tank, and treatment tank. Water softening tank softens raw water containing a hardness component with weakly acidic cation exchange resin. Neutralization tank neutralizes a pH of soft water that has flowed through water softening tank with weakly basic anion exchange resin. Electrolysis tank generates acidic electrolyzed water for regenerating weakly acidic cation exchange resin of water softening tank and alkaline electrolyzed water for regenerating weakly basic anion exchange resin of neutralization tank. Treatment tank mixes the acidic electrolyzed water that has flowed through water softening tank and the alkaline electrolyzed water that has flowed through neutralization tank, and supplies the mixture of the acidic electrolyzed water and the alkaline electrolyzed water to electrolysis tank.

Abstract: A novel method for storing a photocatalytic member containing fluorine-containing anatase-type titanium oxide is provided, which is capable of suppressing the decrease in content of fluorine during storage in a photocatalytic member containing fluorine-containing anatase-type titanium oxide. The storage method of the present invention is a method for storing a photocatalytic member containing fluorine-containing anatase-type titanium oxide including storing the photocatalytic member in a surrounding environment with a relative humidity of 30% or less. According to the storage method of the present invention, for example, the elimination of fluorine from the surface of fluorine-containing titanium oxide can be suppressed, and the decrease in content of fluorine during storage in a photocatalytic member can be suppressed.

Abstract: The vehicle surroundings monitor detects the sizes and positions of obstacles, ditches and humans as well as the depths of the ditches to provide the driver with sufficient information to secure safety during driving. The pattern light projector receives an incoming laser beam and projects a light spot matrix in the form of a regular grating onto the monitored area. The camera photographs the light spot pattern on the monitored area and sends image signals to the data processor which processes the image signals to detect the presence of any obstacle, ditch or human. Based on the steering angle detected by the steering angle sensor, the path the car will take is predicted and a possible contact or collision of the car with the obstacle is detected beforehand. The buzzer, voice synthesizer and display device are used to alert the driver and indicate the presence of the obstacles, the possible contact with them and the location where the possible contact will occur.

Abstract: This invention relates to an instrument for a vehicle in which a front cover is attached to a front face of an instrument case for protecting inside of the instrument. An instrument for a vehicle according to the present invention comprising: a meter; a case for accommodating the meter; and a prism disposed at a front portion of the case for regulating amount of light which is emitted from the prism upward by bending light emitted from the meter downward, the prism also acting as a front cover of the case.

Abstract: A movable crushing apparatus has two skids with wheels. The main skid carrying a crusher and a feeder is adapted to lie on the ground when in use. When moving the apparatus to other place, the point where the two skids are coupled with each other is raised off the ground by a hydraulic jack.
