Patent number: 10022969Abstract: A print device includes a head, a recovery portion, a processor, and a memory. The head is configured to eject a first ink for base printing and a second ink for image printing. The first ink is ejected onto a print medium and the second ink is ejected on the base printing to print image printing. The recovery portion is configured to perform recovery processing. The recovery processing recovers an ejection performance of the first ink of the head. The memory stores computer-readable instructions. When the computer-readable instructions are executed by the processor, the processor acquires an integrated value of an ejection amount of the first ink. And the processor also determines, based on the acquired integrated value, whether to perform the recovery processing by the recovery portion.Type: GrantFiled: September 23, 2016Date of Patent: July 17, 2018Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Takao Hyakudome, Naoki Mizuno, Takamitsu Nakajima

Patent number: 9868280Abstract: A print device includes a head, a recovery portion, and a processor. The head ejects an ink onto a print medium. The recovery portion performs recovery processing to recover an ejection performance of the ink of the head. The processor acquires an integrated value of an ejection amount of the ink, and determines when the integrated value is equal to or more than a reference value, execution of the recovery processing including wiping of a nozzle surface. A nozzle hole is formed in the nozzle surface and ejects the ink. The processor acquires a temperature correlation value corresponding to an environmental temperature, and sets the reference value based on the acquired temperature correlation value such that the reference value when the environmental temperature is a first temperature is smaller than the reference value when the environmental temperature is a second temperature. The second temperature is higher than the first temperature.Type: GrantFiled: September 23, 2016Date of Patent: January 16, 2018Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Takao Hyakudome, Naoki Mizuno, Takamitsu Nakajima

Patent number: 8876544Abstract: A connector can prevent a short circuit between a conductive member positioned on a board and an actuation lever actuatable without an actuation tag. A distance between the board and an actuation portion is larger than another distance between the board and an engage portion under a locked state where the engage portion is engaged with an engaged portion. Under the locked state, the actuation portion is positioned away from the conductive member (a SMT terminal and the conductive pattern formed on the board) so that the actuation lever can be prevented from making the short circuit with the conductive member.Type: GrantFiled: March 22, 2013Date of Patent: November 4, 2014Assignee: Japan Aviation Electronics Industry, LimitedInventors: Takahiro Yamaji, Takamitsu Nakajima

Patent number: 8721366Abstract: A connector is mountable on a circuit board and matable with a mating connector having a mating portion and a mating shell. The connector comprises a housing and a shell. The housing is formed with a receiving portion. The receiving portion is receives the mating portion of the mating connector when the mating portion is inserted into the connector. The shell has a plurality of first connected portions and a plurality of second connected portions. The first connected portions are configured to be connected to the mating shell of the mating connector when the connector and the mating connector are mated with each other. The second connected portions are configured to be connected to the circuit board when the connector is mounted on the circuit board. The first connected portions and the second connected portions extend forward of the receiving portion.Type: GrantFiled: July 26, 2012Date of Patent: May 13, 2014Assignee: Japan Aviation Electronics Industry, LimitedInventors: Takahiro Yamaji, Takamitsu Nakajima

Publication number: 20130260601Abstract: The present invention provides a connector 100 which can prevent a short circuit between the actuation lever 160 and a conductive member positioned on a board 50, and has an actuation lever 160 actuatable without an actuation tag. A distance between the board 50 and an actuation portion 172 is larger than another distance between the board 50 and an engage portion 170 under a locked state where the engage portion 170 is engaged with an engaged portion 202. Under the locked state, the actuation portion 172 is positioned away from the conductive member (a SMT terminal 212 and the conductive pattern formed on the board 50) so that the actuation lever 160 can be prevented from making the short circuit with the conductive member.Type: ApplicationFiled: March 22, 2013Publication date: October 3, 2013Applicant: Japan Aviation Electronics Industry, LimitedInventors: Takahiro YAMAJI, Takamitsu NAKAJIMA

Patent number: 8075324Abstract: A connector assembly includes a receptacle connector and a plug connector matable with the receptacle connector along a mating direction. The plug connector includes a lock activation portion movable between a lock position and an unlock position along an activation direction under a mating state. The receptacle connector includes a detection switch and a deformable lock operation member pivotably mounted to the plug connector that ensures movement of the lock activation portion in a separation direction when the lock activation portion is located at the unlock position under the mating state. The lock operation member has lock member ends that are received by holes of a receptacle shell to retain the plug connector and receptacle connector in the locked position and to effect closure of the detection switch. The detection switch is pressed by the lock activation portion to detect the lock activation portion is located at the lock position.Type: GrantFiled: February 17, 2010Date of Patent: December 13, 2011Assignee: Japan Aviation Electronics Industry, LimitedInventors: Takahiro Yamaji, Masahide Watanabe, Takamitsu Nakajima, Hiroki Kamata, Akira Kimura

Patent number: 4104821Abstract: A battery powered toy telephone capable of playing in random order any one of several recorded messages, and also capable of intermittent ringing of a bell. Operation of the toy proceeds by turning on a switch, by pressing one or more buttons located below the dial of the toy telephone to cause the bell to ring intermittently, and then by removing the headset to play one of the recorded messages. The messages are recorded in separate grooves on a rotating sound disc that is disengaged from a stylus sliding in contact with a speaker cone by replacing the headset or pressing the strut, which must occur between consecutive messages. The bell rings intermittently only when the toy is turned on, the headset is in place or the strut is being pressed, and one of the buttons is being pressed, or has been pressed since replacing the headset or while depressing the strut.Type: GrantFiled: September 1, 1976Date of Patent: August 8, 1978Assignee: Tomy Kogyo Co., Inc.Inventor: Takamitsu Nakajima
