A faucet generator includes; a rotor vane which is disposed in a water supply channel; an annular magnet which is rotatable integrally with the rotor vane; and a stator having: a coil which is disposed to be opposed to an end face of the magnet that is substantially perpendicular to a radial direction; a plurality of inductors which are placed separately from one another along a circumferential direction between the end face of the magnet and the coil; and a yoke which is disposed to be continuously contacted with the inductor and surround the coil. The axial direction of the rotor vane is substantially parallel to the water supply channel. In the annular magnet, the end faces which are substantially perpendicular to a radial direction are alternately magnetized with N and S poles along the circumferential direction of the magnet. In the yoke, cutaway portions which are formed by cutting away portions that are opposed to the circumferential face portion of the coil, and that are in the vicinity of the tip ends of the inductors, in one end that is on the side where said inductors are disposed, whereby portions of the yoke which are in the vicinity of the tip ends of the inductors are formed so as to relatively recede from the magnetic inducible area of the magnet.

A water supply apparatus includes an apparatus body disposed in a flow passage for sucking water to an indoor facility and a power generation unit installed in the apparatus body. Further, the power generation unit further comprises a rotating shaft extended in a direction perpendicular to the water channel direction of the flow passage, and impeller installed on the rotating shaft and rotated by a water flow, a magnet rotated interlockingly with the impeller, and a coil arranged oppositely to the magnet, wherein the impeller forms blades in the radial outer direction and forms clearances allowing water to pass to the inside of the blades. Since the clearances are formed between the blades and the rotating shaft such a trouble that water flowing into the base ends of the blades obstructs the rotation of the impeller can be eliminated to increase a power generation amount by the power generation unit. In addition, since there is no need to expand the flow passage on the outside of the impeller to reduce the rotational resistance of the impeller, the size of the water supply apparatus can be reduced.

A novel water jetting device achieves a water jet of a wide range and an economization of water without using an electric drive device. A water jetting body 10 is so vortex chamber 4 with its water jetting spout 11 confronting the outside of the force receiving member 12 that a force receiving member 12 can oscillate in a position inclined in the vortex chamber 4. A vortex flow thus established in the vortex chamber 4 is caused to make a flow velocity difference around the force receiving member 12, and a force generated on the basis of the flow velocity difference is exerted upon the force receiving member 12 to oscillate the water jetting body 10 in the inclined position in the vortex chamber 4 thereby to jet the cleaning water in the vortex chamber 4 from the water jetting spout 11.

In a policy-change input unit (10), a policy recalculation unit (133) compares, upon occurring of a change request of a privacy policy from a user, an existing policy against an updating policy, recalculates a transmission policy to be transmitted to other providers based on the result of comparison, and transmits the recalculated policy to the other policy. The policy recalculation unit (133) transmits a deletion request of personal information to another provider by using a deletion-request creation unit, upon judging that the another provider cannot use the personal information due to the change of privacy policy.

摘要:
The present invention is intended to allow distribution of personal information to be managed on the basis of not only a personal information management policy defined by a personal information producer but also management policies of all apparatuses which handle personal information when the distribution of personal information is managed between apparatuses. In its configuration, personal information generation apparatus 1 encapsulates personal information together with a transmission policy to generate a personal information capsule which is transmitted to personal information utilization apparatus 2. Personal information utilization apparatus 2 receives and holds the personal information capsule for utilization. In this event, personal information generation apparatus 1 transmits a transmission policy defined by the personal information producer. Personal information utilization apparatus 2 in turn transmits a reception policy defined by a personal information user. Then, personal information generation apparatus 1 and personal information utilization apparatus 2 determine a contractual coverage in regard to personal information to be distributed, and generate contract information. Eventually, the personal information is distributed from personal information generation apparatus 1 to personal information utilization apparatus 2 based on the generated contract information.
