  • Patent number: 10595960
    Abstract: Devices and methods for ultrasonic dental treatment are described, wherein the devices and methods can comprise a flexible array of cooperative ultrasound transducers. The array can contain individual ultrasonic transducers that can perform both functions of emitting and sensing. The transducers can have the ability to interchange their functions from emitting to sensing. The transducers can cooperate in providing an ultrasound treatment and each transducer can be independently controlled by an external source controller. An ultrasound system is provided comprising: an ultrasound transducer sensor array operable to emit or sense ultrasound, wherein the timing and intensity of emission may be controlled by an electronic controller based on a feedback signal from the sensors. In addition the ultrasound system can also have the ability to sense coupling to a treatment tissue. This ability to sense proper coupling can improve the efficacy of the treatment.

    Abstract: At least two sound pressure sensors in parallel with each other are inserted into a liquid to which waves are applied. The sound pressure sensors have a bar-like shape and the same sensitivity. In a first synchronized state waves detected by the sound pressure sensors are synchronized with each other. The sound pressure sensors are moved relative to each other in a longitudinal direction, to break the first synchronized state and then establish a second synchronized state in which the waves detected by the sound pressure sensors are again synchronized with each other. A wavelength of the detected waves is determined according to a quantity of the relative movement of the sound pressure sensors between the first and second synchronized states. The detection of a wavelength of waves applied to the liquid is usable to evaluate and control a total amount of dissolved gases in the liquid.

    Abstract: A cleaning device and method remove a lubricant from the rolls of a roll stand. To achieve economical and efficient cleaning of the rolls, the cleaning device includes at least one ultrasonic generator for generating ultrasonic waves, the ultrasonic waves being routed to the surface of the rolls by cleaning water; and a supply line for the cleaning water. The supply line is a branch of a cooling water circuit for the roll stand, enabling the water consumption for the roll stand to be kept constant during the cleaning phase. The water is merely redistributed in that a portion of the cooling water is supplied to the cleaning device. This creates the advantage of the roll temperature rising slightly, with the result that the cleaning performance is supported by the higher roll temperature at which the lubricant is better released from the surface of the roll.

  • Patent number: 8888925
    Abstract: A nozzle for discharging droplets of a processing liquid for processing a substrate has a main body including a supply port, a drain port, a processing liquid flow passageway connecting the supply port and the drain port, and a plurality of discharge ports from which the processing liquid is discharged. The processing liquid flow passageway includes a plurality of branch flow channels, which branch out between the supply port and the drain port and collect together between the supply port and the drain port. The plurality of discharge ports form a plurality of columns respectively corresponding to the plurality of branch flow channels; and are aligned along and connected to the corresponding branch flow channels. A piezo element applies vibration to the processing liquid flowing through the plurality of branch flow channels.

  • Patent number: 8858718
    Abstract: An automated method of cleaning the pipes of a plate washing system is provided. The plate washing system includes at least one manifold having a plurality of pipes configured to be provided within wells of a plate in order to wash the wells, an ultrasonic transducer mounted to a tank, and a control system. The plate washing system also includes sensors to sense the position of the pipes relative to plate and the tank, and the fluid level within the wells of the plate. The method includes dispensing fluid to the tank, submerging the tips of the pipes within the fluid, activating the ultrasonic transducer in order to vibrate the fluid, and aspirating the fluid from the tank. The control system may initiate a cleaning operation at the request of the user, at a scheduled interval, or when the level sensing system detects a decrease in instrument function.
