  • Patent number: 6719893
    Abstract: Phosphorus is removed from water to be treated by immersing electrodes into a tank filled with the water to be treated, applying a DC voltage between the electrodes to generate hydroxide ions through a cation migration in the water and/or an electrolysis, and precipitating phosphate ions in the water as a salt slightly soluble in water.
    Type: Grant
    Filed: January 23, 2002
    Date of Patent: April 13, 2004
    Assignee: Gunma University

  • Patent number: 6564227
    Abstract: A customer support system uses information concerning device located at customer and supports the customer. A customer support center collects customer information using a communication line, and stores or transferring the information. Customer information systems connected with the customer support center via a communication line, use the information of the customer support center, and support the customer. The customer support center comprises a collector for collecting and distributing usage information and quality information of the device, and a memory storing the usage information and quality information of the device as it is or after modifying it. The customer information systems use the usage information and quality information of the device collected by the customer support center, and support the customers.

  • Patent number: 5541365
    Abstract: To provide a beam welding terminal structure which holds a connection member to be connected, such as a wire, from opposite sides thereof, and firmly welds the connection member by irradiation of a beam such as a laser beam, a beam welding terminal structure includes holding walls at opposite sides, and a connection member to be connected is welded to the holding walls by irradiation of a beam. A projection extends from at least one of the holding walls and beyond the connection member in a direction of the height. A rectangular wave-shaped base wall has longitudinal side portions, extending in a direction intersecting the connection member, and transverse side portions extending parallel to the connection member.

  • Patent number: 5443706
    Abstract: An electrode consists of a cathode matrix material and a biocatalyst immobilized on the matrix material. A water under treatment is treated by disposing the electrode as a cathode and an anode opposed thereto in the water, and applying an electric current between the cathode and the anode.

  • Patent number: 4860170
    Abstract: A pointer illuminating structure in a measuring instrument. A pointer of the measuring instrument is of a generally elongated structure and transparent. At an intermediate portion thereof, a light inducing section is provided to extend substantially perpendicularly to the generally elongated structure to form a T shape. The pointer has a flat upper surface and lower surfaces extending from about both side of the light inducing section. A reflective material is applied to the lower surfaces. Beneath the upper surface and above levels of the lower surface, cavities laterally extend to open sideways. Said cavities are defined by reflective surfaces. In alternative form, said elongated pointer is formed with a truncated conical portion at the light inducing section. Said truncated conical portion has a truncated conical reflective surface. The reflective material is applied to the side surfaces instead of the lower surface thereof.

  • Patent number: 4625262
    Abstract: A pointer illuminating structure in a measuring instrument. A pointer of the measuring instrument is of a generally elongated structure and transparent. At an intermediate portion thereof, a light section is provided to extend substantially prependicularly to the generally elongated structure to form a T shape. The pointer has a flat upper surface and lower surfaces extending from about both side of the light inducing section. A reflective material is applied to the lower surfaces. Beneath the upper surface and above levels of the lower surface, cavities laterally extend to open sideways. Said cavities are defined by reflective surfaces.
