Abstract: A measurement method of a surface shape and a surface shape measurement device uses an interferometer optical head that acquires an interference fringe image generated by a light path difference between the reference light and the measurement light, acquires N interference fringe images by scanning from a start point to an end point in the Z-axis direction, and measures the surface shape of the measurement target surface based on the interference fringe images. For a common position in the N interference fringe images, regarding an interference signal including values of N points that indicates a change in the interference light intensity along the Z-axis direction, a phase of an interference fringe produced by the light of a predetermined analysis wavelength is determined, and the relative position in the Z-axis direction of the measurement target surface within the range of the analysis wavelength is determined based on the phase.

Abstract: A measurement method of a surface shape includes combining N stacked images captured while scanning the measuring head. For a position in the N stacked images, from an integral curve including values of N points, which is obtained by integrating square values or absolute values of the interference signal including values at N points: a start-point-side noise part straight line that approximates a start-point-side noise part, which corresponds to a range where the slope is smaller than the slope in the vicinity of the measurement target surface at the start-point-side than the measurement target surface; an end-point-side noise part straight line that approximates an end-point-side noise part, which corresponds to a range where the slope is smaller than the slope in the vicinity of the measurement target surface at the end-point-side than the measurement target surface; and a surface proximity straight line that approximates surface proximity part.

Abstract: This invention proposes a mattress formed by covering a padding with a covering material, characterized in that the covering material has grip portions fixed to the longitudinal edges near the corners of the mattress, that the ends on one side of multiple fastening belts are fixed to both the longitudinal edges, that stowing portions for stowing the fastening belts are provided, and that fastening members are fixed at the ends on the other side of the fastening belts.

Abstract: An ordinary bed mattress used in an ordinary situation by a person unable to take refuge by himself/herself such as a patient unable to walk or bedridden patient can be used as a component of a stretcher in a disaster situation, if the mattress is contained in the mattress cover of this invention, and the person lying on it can be carried to a safe place for evacuation. This invention proposes a mattress cover for disaster time transportation, comprising a mattress inserting portion for inserting a mattress into the cover, grip portions attached to the cover at the portions corresponding to the corners of the mattress as contained within the cover, and the ends on one side of multiple fastening belts to be fastened across in the transverse direction of the mattress as contained within the cover, being fixed to the cover at the portions corresponding to the longitudinal edges of the mattress as contained within the cover.

Abstract: The object is to provide a mattress that can be used as a stretcher when a disaster occurs and can also be used as an ordinary mattress when it is not used as a stretcher. This invention proposes a mattress 1 formed by covering a padding with a covering material, characterized in that the covering material 3 has grip portions 4 fixed to the longitudinal edges near the corners of the mattress, that the ends on one side of multiple fastening belts 6 are fixed to both the longitudinal edges, that stowing portions 7 for stowing the fastening belts are provided, and that fastening members 9 are fixed at the ends on the other side of the fastening belts.

Abstract: An object of the present invention is to provide a metal oxide particle which exercises more excellent ultraviolet absorbency as a matter of course and combines therewith merits of, for example, either being shifted in ultraviolet absorption edge toward the longer wavelength side and being excellent also in the absorption efficiency of a long-wavelength range of ultraviolet rays, or having good transparency and, for example, even in cases where added into or coated onto substrates, not damaging the transparency or hue of the substrates.

Abstract: An electrophoretic display device uses a liquid-phase electrophoretic material not confined in a shell. An electrophoresis chamber with the electrophoretic material hermetically sealing therein is mounted in a substrate. Also, a display section, a data communication section, a driver section, and a power reception section are mounted on the substrate. The data communication section is communicable with an external device to receive data to be displayed in the display section. The driver section is provided for driving the display section. To supply power to various sections of the display device, the power reception section is provided for wirelessly being supplied with power from an external station. A panel is mated with the substrate to cover the data communication section, the driver section, and the power reception section while exposing a transparent cover plate of the display section.

Abstract: A network management system can detect a security hole on the network and take necessary measures against such a security hole. When the security hole is detected on the network, the security hole is displayed on a drawing of the network configuration. Further, the network management system displays the status of connection from the outside network, the contents of accesses to the computer and the network device, the status of access to the network environment maintenance file, and the status of login procedures executed with the privileged user.

Abstract: A system for operating and managing the network equipment is so adapted as to operate and manage a network in which plural computers and network devices are connected to each other. The system is provided with database storing data corresponding to the computers and the network devices and with means for preparing a network specification drawing which satisfies conditions required by the user from the data, for checking the physical data as to whether the network specification satisfies the physical data, for checking the logical data as to whether the network specification satisfies the logical data, and for displaying the network specification drawing in a two-dimensional or three-dimensional manner on the basis of the data stored in the database. The system for operating and managing the network equipment can reduce and simplify management business for network managers as well as management business for managing materials and products by managers managing the materials and products.
