摘要:
An ion complex which comprises a water-insoluble polyion (P) and a water-soluble polyion (A); and is insoluble in water and soluble in an aqueous organic solvent. Such an ion complex becomes a coating material which can preferably be used for coating of various ionic substances (e.g., substance having biological activity such as an anticoagulant property or an antibacterial property).

A charging generator for a vehicle including a field winding rotated by the rotation of an engine so as to generate a rotating magnetic field; an armature winding responsive to the rotating magnetic field to generate a current and charge a battery via a rectifier; a comparison circuit for comparing a voltage of the battery or a voltage of the rectifier with a predetermined value; a current control circuit for controlling a field current to be supplied to the field winding on the basis of output of the comparison circuit; a voltage change value detection circuit for detecting a change value in the battery voltage or the rectifier voltage; and a load response control circuit for suppressing a rise in the field current to be supplied to the field winding on the basis of an output of the voltage change value detection circuit.
摘要:
An electrophoretic matrix comprised of at least one water-insolubilized, temperature-responsive polymeric compound having an LCST is disclosed. The electro-phoretic matrix can change its hydrophilic/hydrophobic property by changing temperature. A method of using the electrophoretic matrix involves charging a sample onto the matrix and carrying out electrophoresis at a temperature above or below the LCST of the polymeric compound.

[Problems] To provide a system for producing safe and high nutrition vegetables at low cost.[Means to solve the problems] A plant cultivation system for cultivating a plant on a nonporous hydrophilic film, which comprises a nonporous hydrophilic film and a feeding means for supplying water or a nutrient fluid to the lower surface of the film in the absence of a hydroponic tank for accommodating water or a nutrient fluid and cultivating a plant therein. As the feeding means, use is made of a water absorbing material which is in contact with the film and which is disposed between the film and a water impermeable material. A system for producing safe and high nutrition vegetables at low cost can be obtained by disposing the water impermeable material directly on ground soil, whereupon the water absorbing material and an irrigation tube are disposed, followed by disposing the film thereon.

A connector is provided which comprises a metallic sleeve 1 to be attached to an access end 21a of a glass tube 21 in a discharge tube 20, and metallic sleeve 1 is formed into a gapped ring section with longitudinal opposite ends for defining a gap 17. Sleeve 1 can be radially expanded due to gap 17 to attach it to glass tube 21 and firmly be retained on glass tube 21 due to resilient force of sleeve 1 for shrinking the diameter. This arrangement ensures the prevention of misalignment or detachment of sleeve 1 on glass tube 21 even when some external force is applied to sleeve 1 when discharge tube 20 is mounted on a holder, while restricting stress conveyance to a lead 22 of discharge tube 20.
摘要:
A device having a shape capable of receiving the plant body to be cultivated. As at least a portion of the device, a film which can substantially be integrated with the root of the plant body is disposed. Such a structure can provide a plant-cultivating device, a plant-film integrate, and a plant-cultivating method which can preferably attain both of the supply of oxygen and the supply of water and a fertilizer component to the root of the plant body.
摘要:
In an Internet telephone connection method, a communication bandwidth is managed by using a bandwidth controller, gateway devices and voice relay routers to monitor communication quality under bandwidth reservation. A communication path under bandwidth reservation is preferentially selected by using gate keepers and the voice relay routers, and the connection of the Internet telephone is performed. A problematic device is prohibited from being selected as a connection-destination device at the time of a call setup and the problem restoration is monitored by using the gate keepers and the gateway devices. Further, a device having invalid attribute information is prohibited from being selected as a connection-destination device at the time of call-setup, and the restoration of the attribute information is notified to the overall network. Accordingly, the reservation of the communication bandwidth can be performed under the control of the overall network, fixed communication quality can be maintained and reliability can be enhanced.
