Publication number: 20180326723Abstract: The present invention provides a liquid ejecting head in which a chip crack is unlikely to occur. To achieve this, a liquid ejecting head includes an element substrate having energy generating elements arranged on the front face of the element substrate in its longitudinal direction and a channel member having ejection ports formed to correspond to the energy generating elements, respectively. In the element substrate, a supply port for supplying liquid is formed so as to pierce through from a back face to a front face of the element substrate, and inside the supply port, a beam is formed at a position closer to an end of the supply port rather than a center thereof in its longitudinal direction to connect facing inner walls of the supply port in its lateral direction.Type: ApplicationFiled: May 1, 2018Publication date: November 15, 2018Inventors: Takanobu Manabe, Kenji Fujii, Hirohisa Fujita, Keisuke Kishimoto, Yoshinori Tagawa, Hideo Saikawa, Yasushi Iijima, Kenji Yabe, Kyosuke Toda, Yosuke Takagi, Hiroyuki Murayama

Patent number: 9315026Abstract: A method for manufacturing a liquid discharge head. The method includes a first step of forming a telecentric measurement pattern A by exposure, the telecentric measurement pattern A being part of a measurement pattern that allows determination of inclination of a principal ray caused by an off-axis telecentric degree occurring in a projection exposing device, and a second step of forming a telecentric measurement pattern B by exposure under an exposure condition defocused from an exposure condition in the first step, the telecentric measurement pattern B being another part of the measurement pattern, which allows the determination of the inclination of the principal ray caused by the off-axis telecentric degree occurring in the projection exposing device. The off-axis telecentric degree is determined from an amount of misalignment between relative forming positions of the telecentric measurement patterns A and B and an amount of defocusing.Type: GrantFiled: August 12, 2015Date of Patent: April 19, 2016Assignee: Canon Kabushiki KaishaInventors: Takanobu Manabe, Yoshinori Tagawa, Hiroyuki Murayama, Shuhei Oya
