  • Publication number: 20250065547
    Abstract: An injection molding machine system includes an injection molding machine, a mold, a heating heater device, and a pressing device. When the mold is closed or clamped, two or more primary molding cavities and one or more secondary molding cavities are formed. Primary molded articles are molded through injection molding when injected into the primary molding cavities. The pair of primary molded articles are placed in the secondary molding cavity, bonding end surfaces are melted by the heating heater device, and the mold is closed or clamped. When the pair of primary molded articles are pressed together by the pressing device, the primary molded articles are fused to each other to form a molded article.

  • Patent number: 12000611
    Abstract: In an air conditioner of the present embodiment capable of selecting either a fan rotation speed determined on the basis of a static pressure value and an air volume or a required fan rotation speed, motor control means determines, on the basis of the static pressure Pt, the fan rotation speed Rm of a fan motor that provides the air volume Av required by the user, and transmits the determined fan rotation speed Rm to an indoor unit control means. When the fan rotation speed Rm received from the motor control means is a prohibited rotation speed, the indoor unit control means transmits a correction fan rotation speed different from the prohibited rotation speed to the motor control means, and the motor control means drives the fan motor at the received correction fan rotation speed.

  • Patent number: 11828502
    Abstract: A valve structure that may control the flow rate of a fluid when the fluid starts to be released is provided. In a valve structure including a valve sheet having two outlets to release a fluid and a valve body arranged to be rotational against the valve sheet to regulate a degree of opening of the outlet, the valve body has a fluid control recess formed in the circumferential direction whose area overlapping the outlet is changed by rotation of the valve body, and the center of the outlet is forced to deviate from a rotation trajectory of a front end portion of the fluid control recess that starts to overlap the outlet by the rotation of the valve body.

  • Patent number: 11638695
    Abstract: The present invention provides a method for producing lipid particles that have a desired particle diameter, the method comprising: (A) a step for preparing, in a first mixing region, a primary dilution by mixing a first solution containing a lipid and an alcohol with a second solution containing water; (B) a step for feeding the primary dilution from the first mixing region to a second mixing region through a liquid feed pipe within a prescribed time; and (C) a step for preparing a secondary dilution by mixing the primary dilution with a third solution containing water in the second mixing region, wherein the steps (A)-(C) are continuously carried out, and the particle diameter of the lipid particles is controlled by adjusting at least one condition selected from the group consisting of the concentration of the alcohol and the concentration of the lipid in the primary dilution, the prescribed time, and the temperature during mixing.

  • Patent number: 11633699
    Abstract: A dialyzer (15) includes a hollow fiber dialysis column (20), a liquid tubing section (12a), and a flow rate changing section (16a). The hollow fiber dialysis column (20) includes a hollow fiber membrane, a first flow channel that allows a dialysis target to flow internally of the hollow fiber membrane, and a second flow channel that allows an external liquid to flow externally of the hollow fiber membrane. The liquid tubing section (12a) tubes the dialysis target to an inlet (20a) of the first flow channel. The flow rate changing section (16a) is capable of changing a flow rate of the dialysis target at the dialysis target flowing out of an outlet (20b) of the first flow channel.
