Patent number: 9533365Abstract: An electric discharge machining apparatus includes a power supply, an electrode gap formed from an electrode and a workpiece, a current limiting resistor connected between the power supply and the electrode gap, switching elements that turns on and off application of a voltage from the power supply to the electrode gap, an inductance element connected in series between the switching elements and the electrode gap, and a control unit that controls the switching elements. The control unit causes the switching elements to perform ON/OFF operations according to a switching pattern having an on-pulse time width (?Ton) in which a voltage of the electrode gap can reach a voltage value of the power supply in an on-pulse time and a pause time width (?Toff) equal to or longer than a time width (?tic) of a discharge current flowing during the capacitor discharge and shorter than a cycle (?Tso) of the self-excited oscillation.Type: GrantFiled: October 31, 2012Date of Patent: January 3, 2017Assignee: Mitsubishi Electric CorporationInventors: Ieyoung Kim, Takashi Hashimoto, Tomoaki Takada, Takayuki Nakagawa, Yuto Sasaki

Patent number: 9479673Abstract: An image forming apparatus switches between a first processing and a second processing when processing document data. In the first processing, the document data is transmitted to a server without making a determination using a hash value of received document data and a hash value of data transmitted to the server. In the second processing, a determination is made using the hash value of the document data and the hash value of the transmitted data, and, based on a determination result, the document data is transmitted to the server.Type: GrantFiled: June 4, 2015Date of Patent: October 25, 2016Assignee: Canon Kabushiki KaishaInventor: Yuto Sasaki

Patent number: 9442681Abstract: An image forming apparatus instructs job execution, and determines whether processing for performing the job execution is executable in the image forming apparatus. In a case where it is determined that the processing is not executable in the image forming apparatus, the image forming apparatus transmits to a server data for performing the job execution. The image forming apparatus determines whether a job exists in a job list, and transmits to the server a deletion request of the data transmitted to the server, using a result of the determination and a detection result of logout.Type: GrantFiled: October 23, 2015Date of Patent: September 13, 2016Assignee: Canon Kabushiki KaishaInventor: Yuto Sasaki
