  • Publication number: 20240133442
    Abstract: A spring member is provided between two pressed bodies facing each other in a first direction and includes base plates stacked in the first direction. Each base plate is provided with spring protrusions protruding toward either one pressed body of the two pressed bodies and pressing the two pressed bodies in directions such that the pressed bodies move away from each other in the first direction. Between two base plates adjacent to each other in the first direction, a base plate positioned closer to the one pressed body is provided with an insertion hole into which a spring protrusion of the other base plate is inserted in a state of penetrating therethrough in the first direction. Among portions in an along-plane direction along a plane orthogonal to the first direction provided with the spring protrusions, the spring constant of at least one portion is different from that of another portion.

  • Publication number: 20210018474
    Abstract: An asymmetric flow field flow fractionation apparatus 1 is provided with a separation cell having a semi-permeable membrane. Each flow path is connected to the separation cell. A mobile phase that has passed through the semi-permeable membrane of the separation cell flows through a crossflow discharge flow path. The crossflow discharge flow path is provided with a flow controller 14 for adjusting the flow rate. A voltage control unit 332 applies a voltage according to a set flow rate to the flow controller 14 when the set flow rate of the mobile phase of the crossflow discharge flow path is constant, and applies a voltage in which an offset is added to the voltage according to the set flow rate to the flow controller 14 to the flow controller 14 when the set flow rate of the crossflow discharge flow path mobile phase increases.

  • Patent number: 9729754
    Abstract: Embodiments may include a reception processor that receives image data corresponding to an image including a plurality of image objects. A controller may determine whether image objects are in contact with a boundary of a printing area of medium, and, based on a result of the determination, may perform expansion processing on one of the plurality of image objects that is in contact with the boundary of the printing area of the medium to expand image objects in contact with the boundary of the printing area and does not perform expansion processing on image objects not in contact with the boundary of the printing area of the medium such image objects not in contact with the boundary of the printing area are not expanded. Expansion image data including the expanded image objects and image objects on which expansion processing is not performed may be generated and output.

  • Patent number: 8059233
    Abstract: There is disclosed a transflective liquid crystal display having pixels each including a reflective region and a transmissive region. The aperture ratio of the pixels can be enhanced. End portions of two adjacent color filters are overlapped to form an optically shielding portion for each pixel. The optically shielding portion and the reflective region cooperate to form an optically shielding film acting as a black matrix for the transmissive region. The aperture ratio is enhanced by improving the positional relationship between the reflective regions and the color filters.

  • Patent number: 7087928
    Abstract: The present invention realizes an image display of high quality by eliminating a defective display which is attributed to a stepped portion of a light shielding film which is generated in a boundary region by exposure of two or more times using an exposure mask having a size smaller than a size of a display region. Assuming a width of a scanning line GL as WG, a width of a common line CL as WC, an interval between the scanning line GL and the common line CL as WP, and a width of a light shielding film BM1 as WBM, the relationship WBM<WG+WC+WP is established. Further, both end peripheries of the light shielding film BM1 are positioned between an end periphery of the scanning line GL at a side opposite to the common line CL and an end periphery of the common line CL at a side opposite to the scanning line GL.

  • Patent number: 5087853
    Abstract: A magnetron having an anode cylinder, cooling fins fixed thereto, permanent magnets vertically superposed on the anode cylinder and a yoke, serving as a magnetic path, for surrounding these components. The cooling fins extend on the windward direction to facilitate a discharge of the air in the orthogonal direction to the air blowing direction by an arrangement such that an outer width of the fins and a width of the yoke or the former is equalized to a diameter of the anode cylinder. Also included are a dielectric heater having a heating space for accommodating materials for heating and a space for accommodating the magnetron, an inverter power supply and a cooling air blower. The cooling air is discharged to the heating space and/or to the outside via a vent hole formed in a partition wall after impinging on the anode cylinder while cooling the fins.
