  • Publication number: 20230311507
    Abstract: An object is to improve the structural reliability of a liquid ejection head. To achieve this, a liquid ejection head includes a first substrate having ejection ports, liquid chambers, and energy generation elements, and a second substrate joined to a second surface of the first substrate situated opposite to its first surface. The first substrate includes projecting areas projecting from end portions of the second substrate in a planar direction perpendicular to a first-axis direction (z-axis direction). Terminals to be electrically connected to the energy generation elements are provided at the second surfaces of the projecting areas. A support member 401 is joined to the first surface of the first substrate, has an opening at a position opposed to where the ejection ports are formed, and is fixed to the frame.

  • Patent number: 10377059
    Abstract: An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller performs active control in conjunction with the positioning, control by the servomotor. At the beginning of the active control, the positioning control is primarily performed by the servomotor, and then the active control is positively performed by the active controller using an electric actuator. Compared with when only the active control is performed for vibration suppression, a lighter and smaller electric actuator can be employed.

  • Patent number: 10377072
    Abstract: An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.

  • Publication number: 20090217991
    Abstract: A pipe capable of eliminating the adverse influence of a cavity flow on a branch pipe is provided. In a pipe 1 which is branched from a main pipe 3 through which a high-temperature fluid flows and which is configured to be closable, dividing part 5, 7, and 9 are provided in the pipe 1 for dividing a channel in the pipe 1 into a plurality of small channels.
