  • Patent number: 10819203
    Abstract: A linear actuator is provided that has a configuration capable of inhibiting contact between an inner core and a plate spring that is connected to the inner core and an outer core, and which is realized by a configuration that is easy to assemble. A stator is arranged in an opening section of a through-hole in the inner core, and has a spacer through which a shaft passes. An outer frame section of the plate spring is connected to the outer core, and a fixed section of the plate spring is connected to the inner core through the spacer in a state in which the shaft passes therethrough. The spacer includes a penetration section having an insertion hole which the shaft is inserted through, and restriction sections and which restrict a displacement of a predetermined amount or more of the plate spring to the inner core side.

  • Patent number: 10131104
    Abstract: A vulcanization control method and a vulcanization control system are provided that are capable of preventing insufficient vulcanization while shortening a vulcanization time and obtaining an optimal vulcanization time instantly, even when a simple analysis model is used. Data (Xi) of predetermined types of vulcanization-affecting factors (X) are input into a computation device (2) by an input device (6) before vulcanizing a green tire (G). Using the input data (Xi), a change in temperature distribution of a tire cross section over time is calculated with a one-dimensional thermal conduction model for a tire cross-section that passes through a vulcanization rate-limiting section. On the basis of the calculation results, a vulcanization time Tc is instantly calculated. Upon calculating the vulcanization time Tc, a safety time Ts set on the basis of each vulcanization-effecting factor (X) is shortened on the basis of the input data (Xi) of the individual vulcanization-affecting factors (X).

  • Patent number: 9185281
    Abstract: A camera platform system 1 has a camera 11 that takes an image of an object to generate a shot image, camera platforms 12 and 13 that rotate the camera around a pan axis and a tilt axis, and image processors 4, 5, and 6 that generate a display image based on the shot image. When the camera passes a predetermined angle position to rotate around the tilt axis, the image processor generates a first display image corresponding to an image formed by rotating the shot image by an angle larger than 0 degree and smaller than 180 degrees around the pan axis at the predetermined angle position before generating a second display image corresponding to an image formed by rotating the shot image by 180 degrees around the pan axis.

  • Patent number: 7279067
    Abstract: In a port structure 16A in a semiconductor processing system 2, a door 20A is disposed in a port 12A defined by upright wall 52 and 54. A table 48 opposed to the port is disposed outside the system. Defined on the table is a mount region 76 for mounting an open type cassette 18A for a process subject substrate W. A hood 50 is disposed rotatable relative to the table. The hood defines in its closed position a closed space surrounding the mount region and port, the space having a size to receive the cassette. First ventholes 58 are formed in the upright walls and/or the door so as to introduce gas from within the system into the closed space in the hood. Second ventholes 72 are formed in the table so as to discharge the gas can be discharged out of the closed space.
