  • Patent number: 7347553
    Abstract: A focusing unit (11) is constituted of a prism base (11a), deflection prisms (11b and 11c), and a slit chart (11e) having a slit opening (11d), and the deflection prisms (11b and 11c) are arranged so that deflecting directions may become reverse. The slit opening (11d) is made equally to spread across the deflection prisms (11b and 11c) approximately and is impermeable except the slit opening (11d), and light incident on the deflection prisms (11b and 11c) passes only this slit opening (11d). In addition, the light which is emitted by a focus index illumination light source illuminates the slit opening (11d) through the deflection prisms (11b and 11c). As to an image of the illuminated slit opening (11d), two slit images are formed on a fundus of eye by actions of the deflection prisms 11b and 11c. Focus adjustment is made by aligning these slit images (S1 and S2) in a straight line.

  • Publication number: 20070185688
    Abstract: A computer-readable recording medium storing a system analysis program capable of detecting changes in behavior occurring in a very short time without fail. An address data storing unit obtains an address being accessed by a CPU at prescribed sampling intervals, stores address data comprising the address and its acquisition time in an address record table in time series. Then an executed process detector detects the name of the process that was executed when the address data was obtained, and sets the process name for the address data in the address record table. When an analysis request specifying an analysis time period is made, an analyzer counts up each of the process names included in the address data being stored in the address record table for each specified analysis time period, and analyzes the breakdown of executed processes for each analysis time period. Then a display unit displays the analysis result of the analyzer.

    Abstract: A radiographic imaging method controls a radiographic imaging apparatus comprises a support member which supports the subject while defining a backward direction going from the center of the rotation to the back of the subject. The method sets two rotational positions at which the backward direction and an irradiation direction going from the radiation source to the center of the rotation intersect approximately at right angles, as an irradiation start position and an irradiation end position for the radiations. The method designates one of the two rotational positions which is located in a range in which the angle formed by the backward direction and the irradiation direction decreases with the rotation is designated, as the irradiation start position.
