  • Patent number: 8727533
    Abstract: A fundus camera includes an optical path splitting unit arranged between a focusing unit and an imaging unit. The splitting unit has characteristics adapted to reflect light of a visible light region and to transmit near-infrared light. The splitting unit retreats from an optical path when a still fundus image is photographed. A quick-return mirror having such characteristics is used as the splitting unit. When near-infrared illumination light having a wavelength of about 850 nm is used, such light can be incident upon the imaging unit without loss of the amount of light. Visible light output from an internal fixation target is projected onto a subject's eye. A cornea diaphragm and a crystalline lens diaphragm are used for observing a fundus with invisible light. Each of the cornea diaphragm and crystalline lens diaphragm can be changed to another one having a different diameter.

  • Publication number: 20140079418
    Abstract: An image forming apparatus includes a power source to output a voltage having an alternating waveform to transfer a toner image from an image bearing member to a recording medium. A time-averaged value (Vave) of the voltage has a polarity in a transfer direction, in which the toner image is transferred from the image bearing member to the recording medium, and an absolute value of the time-averaged value is greater than a midpoint value (Voff) of the voltage intermediate between a maximum value and a minimum value of the voltage. As a roughness of the recording medium increases, a duty ratio (Duty) expressed by A/(A+B) is reduced, where A is an area of the waveform of the voltage in a return direction opposite the transfer direction relative to the midpoint value in one cycle and B is an area in the transfer direction relative to the midpoint value.

  • Patent number: 8651101
    Abstract: A nebulizer kit includes a case body, a flow channel formation member that covers an opening in an upper area of the case body, and a cylindrical aerosol discharge port that passes through a portion of the top surface of the flow channel formation member located toward the outer edge thereof. The case body and/or the flow channel formation member includes a rotation mechanism that, when the case body has overturned and the aerosol discharge port has become positioned on the lower side in the vertical direction of the top surface of the flow channel formation member, causes the case body to rotate in a circumferential direction to cause the aerosol discharge port to move away from a lower side in the vertical direction. Even if the nebulizer kit has overturned, a liquid within the nebulizer kit is prevented from spilling.
