Patent number: 11967294Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.Type: GrantFiled: May 1, 2023Date of Patent: April 23, 2024Assignee: Sharp Display Technology CorporationInventors: Masaki Uehata, Yasuki Mori, Kohji Saitoh, Takayuki Mizunaga, Kazuya Kondoh, Takashi Nojima, Kazuhisa Yoshimoto, Kosuke Kawamoto, Hiroyuki Kito, Kazuki Nakamichi

Patent number: 11940007Abstract: A tube is used in fiber-reinforced plastic power transmission shaft. The tube comprises: a cylindrical body section; a connection portion that has a larger diameter than the body section; and an inclined portion that has an outer diameter that increases toward the second connection section from the main body part. The inclined section has formed thereon, a weak section that is damaged when a load input in the axial direction exceeds a prescribed value. With this configuration, the cost of the tube can be reduced, and when a prescribed load is input to the tube in the axial direction, the tube is reliably damaged.Type: GrantFiled: March 8, 2021Date of Patent: March 26, 2024Assignee: HITACHI ASTEMO, LTD.Inventors: Kenichi Mori, Takahiro Nakayama, Kazuki Ohta

Publication number: 20220266393Abstract: Irradiation conditions for a laser beam to respective ones of a plurality of regions included in the upper surface of an ingot are set according to the numbers of photons of fluorescence occurring when excitation light is irradiated to the respective regions. Here, it is to be understood that the number of the photons of the fluorescence occurring from a region of an ingot depends on the concentration of an impurity doped in the ingot. A separation layer can therefore be formed at a uniform depth from the upper surface of the ingot even if regions of different impurity concentrations are included in the ingot.Type: ApplicationFiled: February 3, 2022Publication date: August 25, 2022Inventors: Kazuki MORI, Kazuya HIRATA

Patent number: 11214247Abstract: The vehicle control device includes a target detection sensor and a control device that controls the operation of actuators. The target detection sensor can detect the relative speed of a target, positioned in a detectable area, with respect to the vehicle but cannot detect the relative speed when the target exists in a short distance area. The control device calculates the change amount of the relative speed per unit time. When the target enters the short-distance region, the control device calculates the estimated relative speed based on the elapsed time from the last acquisition time, which is the time when the relative speed of the target was last acquired from the target detection sensor, to the current time, the last acquired relative speed that is the relative speed of the target at the last acquisition time, and the time rate of change.Type: GrantFiled: April 7, 2020Date of Patent: January 4, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Mase, Shoichi Inaba, Kazuki Mori
