Publication number: 20220200487Abstract: Provided is an injector in which adhesion between a stator and a rotor of an ultrasonic motor can be released efficiently. An injector (1) which injects a chemical liquid includes: an ultrasonic motor unit (3) including an ultrasonic motor (31); a drive mechanism (4) to be driven by the ultrasonic motor unit (3) so as to feed the chemical liquid when the ultrasonic motor (31) rotates forwardly; and a control device (5) which controls the ultrasonic motor (31) of the ultrasonic motor unit (3). The ultrasonic motor (31) includes a stator (32) and a rotor (33), and the control device (5) controls the ultrasonic motor (31) to alternately repeat forward rotation and reverse rotation so that adhesion between the stator (32) and the rotor (33) is released.Type: ApplicationFiled: March 10, 2022Publication date: June 23, 2022Applicant: NEMOTO KYORINDO CO., LTD.Inventors: Toshio KANETAKA, Makoto UDAGAWA, Toshiiku SASHIDA

Publication number: 20210327986Abstract: The present invention provides a TFT that has a channel length particularly longer than that of an existing one, specifically, several tens to several hundreds times longer than that of the existing one, and thereby allowing turning to an on-state at a gate voltage particularly higher than the existing one and driving, and allowing having a low channel conductance gd. According to the present invention, not only the simple dispersion of on-current but also the normalized dispersion thereof can be reduced, and other than the reduction of the dispersion between the individual TFTs, the dispersion of the OLEDs themselves and the dispersion due to the deterioration of the OLED can be reduced.Type: ApplicationFiled: June 30, 2021Publication date: October 21, 2021Inventors: Makoto Udagawa, Masahiko Hayakawa, Jun Koyama, Mitsuaki Osame, Aya Anzai

Publication number: 20210295773Abstract: A-light-emitting device which realizes a high aperture ratio and in which the quality of image is little affected by the variation in the characteristics of TFTs. The channel length of the driving TFTs is selected to be very larger than the channel width of the driving TFTs to improve current characteristics in the saturated region, and a high VGS is applied to the driving TFTs to obtain a desired drain current. Therefore, the drain currents of the driving TFTs are little affected by the variation in the threshold voltage. In laying out the pixels, further, wiring is arranged under the partitioning wall and the driving TFTs are arranged under the wiring in order to avoid a decrease in the aperture ratio despite of an increase in the size of the driving TFT.Type: ApplicationFiled: April 5, 2021Publication date: September 23, 2021Inventors: Mitsuaki OSAME, Aya ANZAI, Jun KOYAMA, Makoto UDAGAWA, Masahiko HAYAKAWA, Shunpei YAMAZAKI
