  • Patent number: 11953820
    Abstract: An aperture unit includes a base plate, a cover, a plurality of aperture blades, a drive ring, and protrusions. The aperture blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of an opening. The drive ring is disposed between the base plate and the cover, and is rotationally driven when the aperture blades are opened and closed. The protrusions are provided to the drive ring and the cover, respectively, and support the aperture blades in the direction of suppressing upward warpage of the aperture blades in a state in which the aperture blades move in the direction of reducing the size of the opening.

  • Patent number: 8216818
    Abstract: An object of the present invention is to provide a novel ketose 3-epimerase, a process for producing the same, a DNA encoding the enzyme, a recombinant DNA and transformant comprising the DNA, and a process for producing a ketose by using the enzyme. The present invention solves the above objects by providing a ketose 3-epimerase which is obtainable from a microorganism of the genus Rhizobium, a process for producing the same, a DNA encoding the enzyme, a recombinant DNA and transformant comprising the DNA, and a process for converting D- or L-ketohexose into corresponding D- or L-ketohexose by epimerizing the hydroxyl group at the C-3 position of the D- or L-ketohexose; and D- or L-ketopentose into corresponding D- or L-ketopentose by epimerizing the hydroxyl group at the C-3 position of the D- or L-ketopentose; by using the enzyme.

  • Publication number: 20080033309
    Abstract: A blood pressure measurement device includes a fixed main body unit and a removable display unit. The main body unit includes a cuff mounted on a region for measurement of a living body, a control unit including a CPU for measuring a blood pressure with adjusting a pressure of the cuff, and a main body operation unit operated by a subject to externally provide instructions for a measurement operation of the control unit. The display unit includes a display memory storing data of the measurement with the control unit, a display portion displaying measurement data in the display memory, and a display operation unit operated by a subject to externally provide instructions for a display operation of the display portion. A measurement result stored in the display memory of the removable display unit can be displayed on the display portion by operating the display operation unit when the display unit is removed from the main body unit.

  • Publication number: 20060082947
    Abstract: In turn-on state, it is monitored whether a power switch 15 is pressed or not (ST1). When not pressed, it is continuously monitored whether pressed or not. When it is judged that the power switch 15 is pressed, it is monitored whether the power switch 15 is pressed continuously for no less than 2 seconds or not (ST2). When it is judged that the power switch 15 is not pressed continuously for no less than 2 seconds, back to ST1, it is continuously monitored whether the power switch 15 is pressed or not. When it is judged that the power switch 15 is pressed continuously for no less than 2 seconds, the process of turning off the power is started (ST3).

  • Publication number: 20050251052
    Abstract: A cuff for blood pressure monitor includes an air bag for pressing an upper arm, a curled elastic member wound annularly on the outside of the air bag and changeable in size in a radial direction, and a cover having a bag shape for including the air bag and the curled elastic member. The curled elastic member has an overlapping region in which one end and the other end thereof in a circumferential direction are overlapped with each other. The cuff has a sticker serving as an indicator for showing a spot to be held by hand in the fitting operation on a surface thereof at a position corresponding to a region opposing to the overlapping region of the curled elastic member or a region closer to the one end of the curled elastic member than the opposing region in the non-fitting state.
