Abstract: The present invention relates to finger authentication and improves a fingerprint authenticating function by excluding errors caused depending on detection forms. When a fingerprint is detected, form data representing the detection form are captured and, when inputted fingerprint data are compared with registered fingerprint data, authentication is executed referring to the form data. Thereby, the errors caused depending on the detection forms can be excluded and the fingerprint authenticating function is improved. A plurality of different detection form of fingerprint data are registered, a comparison target is selected from the fingerprint data, and the comparison target is compared with the inputted fingerprint data. Thereby, the fingerprint authenticating function is improved.

Abstract: Integrally formed plastic segments comprising an inner surface plate constituting an inner peripheral surface and lateral plates vertically arranged on an edge part of the inner surface plate extending in a circumferential direction are coupled in a circumferential direction to assemble pipe units 10, 10?. The pipe units are coupled sequentially in the longitudinal direction of a pipe, and a rehabilitating pipe is laid down in an existing pipeline. When an existing pipe 21 is bent, the pipe units are coupled at a bending part 21b in the longitudinal direction of the pipe via coupling members so that central axes X1, X2 of the pipes are angled toward each other to create a bend. A gap formed between the pipe units at the bent part is covered by a cladding. Such a configuration enables a rehabilitating pipe to be watertight and resistant to external forces.

Abstract: A rehabilitating pipe is assembled inside an existing pipe using segments to repair the existing pipe. A coupling member is inserted through a segment when it is coupled in the longitudinal direction to another segment coupled already, and the coupling member is joined to the coupling member of another segment already coupled. During joining the segment is clamped against another segment and both the segments are coupled in the longitudinal direction. Such steps are repeated to couple other segments to segments already coupled until the rehabilitating pipe is laid to a predetermined length.

Abstract: A segment (1) is an integrally formed plastic unit comprising an inner-surface plate constituting an inner circumferential surface and lateral plates and end plates that are vertically arranged on a rim of the inner-surface plate. The segments are linked in a circumferential direction and in a pipe length direction to construct the rehabilitating pipe. A pipe unit (10) is made from segments linked in the circumferential direction. A band (30) is attached for encircling the outer circumference of the pipe unit and restraining same. A fastening force is produced on the band by a metal fastener, and the pipe unit is restrained in a fastened state by the band. Therefore, the pipe unit does not readily deform due to external forces, and the strength of the rehabilitating pipe itself can be increased.

Abstract: A highly-sensitive, pyroelectric infrared sensing method and apparatus that can detect infrared temperature with high sensitivity throughout the entire electromagnetic wave range including millimeter waves and radioactive rays. The supersensitive infrared sensor is an infrared sensor of a type that emits electrons from a surface of a ferroelectric body having no emitter. Therefore, a gate electrode is not required to be provided in the vicinity of an emitter. Accordingly, since electrons are emitted directly from a PZT thin film, which serves as a ferroelectric body, in proportion to a temperature variation caused by irradiation of an infrared ray, only provision of an anode is required. Further, designation of machining conditions of the surface of the ferroelectric body is unnecessary.

The segment comprises an inner plate that defines the inner circumferential surface of the rehabilitating pipe and has an opening therein for performing the work of mutually coupling the segments in the circumferential direction of the rehabilitating pipe, and a cover that is fitted into the opening from the bottom surface side of the inner plate. To fix the cover to the inner plate, the cover is provided with a projection and with an engaging member that is movable between non-engaging and engaging positions. The cover is fitted into the opening with the projection into engagement with the inner plate on one side edge of the opening and the engaging member is then brought into engagement with the inner plate on the other side edge thereof, thereby fixing the cover to the inner plate to plug the opening thereof.
