Publication number: 20240017545Abstract: A liquid ejecting apparatus is configured to transition to a first mode in which less electric power is consumed per unit period than in the printing operation and a second mode in which less electric power is consumed per unit period than in the first mode. The second mode is started at the end of a predetermined period of time following completion of the printing operation. The first mode is started after the printing operation is completed and before the second mode is started. The period of time taken for the liquid ejecting apparatus to return to the printing operation from the first mode is shorter than the period of time taken for the liquid ejecting apparatus to return to the printing operation from the second mode.Type: ApplicationFiled: July 12, 2023Publication date: January 18, 2024Inventors: Yuji SHINGU, Jun SATO, Masaya HARAYAMA, Hiromitsu ORII

Patent number: 9923428Abstract: A motor device may include a motor comprising a motor shaft protruded from a motor main body; a worm gear connected with the motor shaft through a coupling; a worm wheel engaged with the worm gear; and a frame on which the motor, the worm gear and the worm wheel are mounted. The coupling may include a motor side coupling part; a transmission member; and a worm gear side coupling part. The motor side coupling part and the transmission member may be relatively movable in a first direction perpendicular to the axial line direction. The transmission member and the worm gear side coupling part may be relatively movable in a second direction perpendicular to the axial line direction and intersecting the first direction. A compression coil spring may be disposed between the transmission member and an end part of the worm gear.Type: GrantFiled: February 28, 2014Date of Patent: March 20, 2018Assignee: NIDEC SANKYO CORPORATIONInventors: Mamoru Yamaoka, Takafumi Kasuga, Yuji Shingu

Patent number: 9859771Abstract: A motor device may include a motor including a motor shaft protruded from a motor main body; a worm gear connected with the motor shaft through a transmission mechanism and is formed with a spiral groove; and a worm wheel engaged with the worm gear. The transmission mechanism may include a transmission member to transmit rotation of the motor shaft to the worm gear. One end face on the motor main body side of the worm gear and an end face on a worm gear side of the transmission member may be formed with two protruded parts protruded toward the other of the end faces, and a recessed part engaged with the protruded parts is formed in the other of the end faces. A compression coil spring may disposed between the worm gear and the transmission member between the two protruded parts.Type: GrantFiled: February 28, 2014Date of Patent: January 2, 2018Assignee: NIDEC SANKYO CORPORATIONInventors: Mamoru Yamaoka, Yoshinori Ogawa, Takafumi Kasuga, Yuji Shingu

Patent number: 4156825Abstract: The present invention provides a high voltage generating device utilizing a piezoelectric element. The device comprises an outer rotary member having a plurality of saw tooth-like cam lobes formed on its outer circumference equidistant from each other and an inner rotary member disposed in the outer rotary member. A cam follower for applying an impact to a piezoelectric element is biased toward the outer rotary member to cooperate with one of the cam lobes. The inner rotary member has a ball mounted therein and a spring for biasing the ball radially outwardly into operative engagement with an inner surface of the outer rotary member. The inner surface of the outer rotary member is so constructed and arranged as to permit free rotation of the inner rotary member unless the inner rotary member is depressed and turned in a predetermined direction.Type: GrantFiled: May 5, 1978Date of Patent: May 29, 1979Assignee: Matsushita Electric Industrial Company, LimitedInventors: Kaneichi Kondo, Kunitoshi Kawano, Yuji Shingu
