Abstract: An inlet (37a) of a capillary tube channel that feeds a liquid from a mixing cavity (39) to measurement spots is formed near one (4) of the wall surfaces of the upper and lower surfaces of the mixing cavity (39) situated in a direction of oscillation for mixing. On the other wall surface (3), a level difference (39a) is formed such that an inner gap is larger than an outer gap in the mixing cavity (39), so that a solution is reliably fed from the mixing cavity to the measurement cells.

The controller transmits first data, addressed to the second communication apparatus, to the second network, transmits second data, addressed to the first communication apparatus, to the first network, causes the speaker to convert into corresponding voice a second voice signal addressed to the mobile communication terminal, and transmits a first voice signal.

Abstract: A measurement cell (40a) is formed so as to extend in a direction along which a centrifugal force is applied, and a capillary area (47a) to which a sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell (40a), the side walls being arranged in a rotational direction. The capillary area (47a) extends from the outer periphery position to the inner periphery of the measurement cell (40a), thereby reducing the size of an analyzing device. Further, the sample liquid in the measurement cell (40a) is sucked to the capillary area (47a) by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area (47a) to the measurement cell (40a). It is therefore possible to achieve a sufficient agitating effect and conduct measurement with a small quantity of sample liquid.

Abstract: An image capture device comprises a camera body held by a user for capturing an image, a display for displaying an image while captured, and a virtual image optical system for producing a virtual image of the image displayed on the display. The display is openably/closably supported by the camera body and positioned in opened/closed positions to expose or unexpose an image display surface. The optical system is contained in the camera body to produce a virtual image of the image on the display to allow the user to observe the virtual image through a viewing opening of the camera body. The user, even if presbyopic, can clearly observe an image, while captured, through the viewing opening. This device has reduced cost and improved design, and allows a user, even if presbyopic, to clearly observe an image while captured, and can prevent degradation in the quality of the observed image.

Abstract: An IP telephone terminal outputs a call request for communication with a prescribed terminal and, if it is determined that connection failed, records the input voice. Thereafter, the IP telephone terminal determines that the prescribed telephone terminal has reached a state connectable through IP network, outputs a call request for communication with the prescribed terminal and if connection is determined to be established, transmits the recorded voice to the prescribed terminal.

Abstract: In an afterglow fluorescent lamp having a structure wherein at least a phosphorescent phosphor layer is set on the internal surface of a glass container, pinholes are prevented from appearing in the layer. The layer is formed, using a phosphorescent phosphor powder, wherein a metal oxide powder whose primary particles have a particle-size distribution with an upper limit particle size smaller than a lower limit particle size of a particle-size distribution that primary particles of a matrix material of the phosphorescent phosphor powder have is mixed, in a ratio by weight that is not less than 10 wt % but not greater than 40 wt %, with the matrix material of the phosphorescent phosphor powder. Therein, the particles of the metal oxide fill the gaps among the particles of the phosphorescent phosphor, and thereby the adhesive strength between the particles of the phosphorescent phosphor is heightened.

Abstract: An image display apparatus has a display section for displaying an image, an eyepiece optical system, and a transparent plate-shaped member for holding the eyepiece optical system. The image display apparatus is used with the eyepiece optical system placed in front of a viewer's eyes and with the plate-shaped member facing the eyes. The image display apparatus directs light from the display section through the eyepiece optical system to the eyes so that the viewer is presented with a virtual image of the image displayed on the display section and simultaneously permits light from the outside world to be transmitted through the plate-shaped member so as to be directed to the eyes so that the viewer is presented with an image of the outside world. The boundary surface between the eyepiece optical system and the plate-shaped member is so arranged as not to reflect light from the outside world incident thereon at angles of incidence greater than the Brewster angle toward the eyes.
