  • Patent number: 10462280
    Abstract: A telephone sends, in accordance with a user's instruction, a call connection request that includes a source telephone number and a destination telephone number to a connecting device or VoIP server device that corresponds to the source telephone number. Management server device, upon identifying a set of a source telephone number and a destination telephone number that is more appropriate than a set of those included in the call connection request, sends a notice to the telephone to prompt a user to change the telephone numbers. The connecting device or VoIP server device that establishes a call connection in accordance with the call connection request, notifies a destination telephone of a to-be-notified telephone number that is selected by the management server device based on the destination telephone number.

  • Patent number: 9901962
    Abstract: There are provided an ultrasonic cleaning apparatus and an ultrasonic cleaning method capable of suppressing occurrence of damage on a substrate to be cleaned and capable of performing cleaning at a high cleaning level for highly precise substrates and the like used in an electronics industry. Occurrence of damage on the substrate to be cleaned is suppressed by holding an object to be cleaned so as to be positioned out of a region where perpendiculars extend from an oscillating surface of an ultrasonic transducer to a liquid surface (an ultrasonic-irradiated region) under and in the vicinity of the liquid surface of a cleaning solution, exciting a capillary wave on a surface of the cleaning solution by an ultrasonic wave, and separating particulate contamination of the object to be cleaned by an acoustic pressure generated by the capillary wave without irradiating the object to be cleaned directly with the ultrasonic wave.
