Patent number: 11970390Abstract: The present disclosure provides a method for producing a microchannel device, which can form a channel that has high hydrophobicity, high solvent resistance as well, and also resistance to heat and damage, on demand with high accuracy, and produces the microchannel device at a low cost, while having high productivity. The method for producing a microchannel device includes: forming a channel pattern from a hydrophobic resin on a porous substrate by an electrophotographic method; melting the channel pattern by heat to allow the channel pattern to permeate into the porous substrate, thereby forming a channel in the inside of the porous substrate.Type: GrantFiled: February 22, 2022Date of Patent: April 30, 2024Assignee: Canon Kabushiki KaishaInventors: Takeshi Yamamoto, Jun Miura, Keiji Miyazaki, Hiroki Tanaka, Makoto Fukatsu, Akihisa Matsukawa, Takayuki Kanazawa, Keigo Mizusawa, Masanori Seki, Masanori Tanaka

Publication number: 20240092337Abstract: A vehicle control apparatus includes front-wheel and rear-wheel driving systems, and a control system. The front-wheel driving system includes a first travel motor mechanically coupled to a front wheel of a vehicle and a first accumulator electrically coupled to the first travel motor. The rear-wheel driving system includes a second travel motor mechanically coupled to a rear wheel of the vehicle and a second accumulator electrically coupled to the second travel motor. The control system includes one or more processors and one or more memories communicably coupled to the one or more processors, and controls the first and second travel motors. When a difference between an SOC of the first accumulator and an SOC of the second accumulator is greater than a threshold value, the one or more processors change a torque distribution ratio between the first and second travel motors from a reference distribution ratio.Type: ApplicationFiled: September 13, 2023Publication date: March 21, 2024Inventors: Hiroshi KUSANO, Yoshinobu YAMAZAKI, Masami OGURI, Akihiro NABESHIMA, Yoshiyuki JIN, Takeshi YONEDA, Fumiya SATO, Keigo YAMADA, Takumi ARAKI, Shuntaro MIURA
