Patent number: 10420267Abstract: An electronic component mounting apparatus includes: a mounting head including a holder for extracting an electronic component and mounting the electronic component onto a substrate, the mounting head being movable in a horizontal direction; an imaging camera disposed on the mounting head for imaging a component extraction position, when the holder is at the component extraction position; a recognition unit for recognizing, based on an image captured by the imaging camera, a positional deviation between the component extraction position and a position of a housing portion where a component is stored in a component feeding unit or a position of the component in the housing portion; and a controller for correcting the component extraction position to a position shifted by a positional deviation recognized by the recognition unit before the component feeding unit extracts a subsequent component, and causing the mounting head to move to the corrected position.Type: GrantFiled: April 8, 2015Date of Patent: September 17, 2019Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Osamu Kanai, Kunimune Komaike, Hideyuki Kamasuka

Patent number: 10027747Abstract: A terminal communication apparatus has a terminal communication control portion rendering an immediate communication control portion sequentially transmitting serial data to another terminal communication apparatus bitwise when receiving a packet as bitwise serial data and a normal communication control portion performing processing on the packet after accumulating the serial data until the serial data reaches a packet length when receiving the bitwise serial data switchable, performing processing with the immediate communication control portion in a case of receiving a time adjustment packet containing time adjustment data posting a timing of synchronization in the other terminal communication apparatus and performing processing with the normal communication control portion in a case of receiving a packet other than the time adjustment packet. Thus, synchronization of control object devices can be enabled without previously investigating communication delay times.Type: GrantFiled: January 14, 2015Date of Patent: July 17, 2018Assignee: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Takashi Saegusa, Ikuo Takemura, Hideyuki Kamasuka, Masahiro Koyama, Terunobu Funatsu
