摘要:
A torsional ultrasonic vibrator particularly adapted for treating teeth by exposing them to ultrasonic waves in the presence of a tooth-decay retarding agent which engages the teeth. A shaft which has a central axis has fixed thereto a blade which projects from the latter axis while having a size small enough to be situated in the mouth of an individual to be treated and large enough to extend along a plurality of teeth in the mouth. A vibrator is operatively connected with this shaft for angularly oscillating the same about the above axis at an ultrasonic frequency.

An appliance for treating teeth, such as human teeth, by providing them with a reinforcing acid-resistant layer of a tooth decay retarding agent. The appliance includes a vibrator for producing ultrasonic vibrations, this vibrator terminating in an elongated vibratory tip. A casing houses the vibrator and has a tubular open end region in which the tip is at least partly accommodated. This tubular open end region of the casing carries an elastic membrane wall which extends across the tubular open end region of the casing and through which the tip extends so that the tip has a free end situated outwardly beyond this elastic membrane wall. The elastic membrane wall fluid-tightly engages the vibratory tip while surrounding the latter, and the membrane wall maintains this fluid-tight engagement with the tip during vibration thereof. The tubular open end of the casing is adapted to be attached to a tray which has a hollow interior provided with a liquid vibration-transmitting medium, the tip piercing into the interior of the tray to engage the liquid medium therein when the tray is attached to the casing at the tubular open end region thereof.

A device for exposing teeth to radiation of ultrasonic waves while the teeth are contacted by a decay-retarding agent, for forming a reinforcing layer of the latter agent on the teeth. In addition to a generator for generating ultrasonic waves, the device includes a support structure which carries a plate capable of transmitting and reflecting the ultrasonic waves. The latter plate is situated between the generator and teeth toward which waves are generally directed from the generator, so that the latter waves are received by this plate which transmits part of the waves through the plate to the teeth at the side of the plate opposite from the generator while another part of the waves are reflected by this plate away from the teeth which receive the transmitted waves, so that in this way the reflected waves may be utilized to treat additional teeth.

For the purpose of forming a reinforcing layer of a decay-retarding agent on the surface of teeth, a device is provided for transmitting ultrasonic waves to the teeth while the latter are in contact with a decay-retarding agent. The device includes an enclosure which is adapted to contain a medium for transmitting ultrasonic waves, this enclosure including a sheet material which defines a hollow interior space in which an ultrasonic wave transmitting medium is adapted to be located. This sheet material of the enclosure has the property of being impermeable to the ultrasonic wave transmitting medium, so that the latter cannot pass through the sheet material. In addition, the sheet material has the property of transmitting ultrasonic waves therethrough. Thus, when a part of the sheet material is situated in the immediate vicinity of a tooth in contact with a decay-retarding agent which also engages the tooth, ultrasonic waves can be transmitted through the medium and through the sheet material so as to act on the decay-retarding agent and the teeth to form thereon a reinforcing layer of the decay-retarding agent.

A vehicle 10 according to an embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. In a state where the connector 21 of the electric power cable 20 is connected with the inlet of the vehicle 10, an electric power is discharged/supplied from the vehicle electric storage device 11 to an external electric load (e.g., external electric storage device 41). Further, the vehicle electric storage device 11 is capable of being charged by the external power supply 50 through the electric power cable 20. A control device 12 of the vehicle 10 obtains/detects a permissible current value of the electric power cable 20, based on a specific signal (control pilot signal) which is transmitted through a CPLT terminal of the connector 21 before it starts the discharge to the external electric load from the vehicle electric storage device 11.

摘要:
A vehicle 10 according to the embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. From the HEMS 40 to the vehicle 10, a request for charge to charge an electric storage device 11 and a request for discharge to allow an external electric load to use an electric power of the electric storage device 11 are transmitted. When a request is changed from the request for charge to the request for discharge, or vice versa, the vehicle 10 realizes a charge-discharge stop state in which neither a charging operation nor a discharging operation is performed without directly changing from the charging operation to the discharging operation, or vice versa.
