A spectrometric analyzing device is capable of analyzing a thin film with high accuracy by using light having an arbitrary wavelength, such as not only infrared light but also visible light, ultraviolet light and X-ray, and using whatever refractive index of a supporting member of the thin film. A spectrometric analyzing device comprises a light source (1), a polarizing filter (2), a detection unit (3), a regression operation unit (4) and an absorbance spectrum calculation unit (5). The light source (1) emits light at n different angles of incidence (θn) to a measurement portion. The polarizing filter (2) shields an s-polarized component. The detection unit (3) detects transmitted spectra (S). The regression operation unit (4) uses the transmitted spectra (S) and a mixing ratio (R) to obtain an in-plane mode spectrum (sip) and an out-of-plane mode spectrum (sop) through a regression analysis. The absorbance spectrum calculation unit (5) calculates an in-plane mode absorbance spectrum (Aip) and an out-of-plane mode absorbance spectrum (Aop) of the thin film, based on the results from a state in which the thin film is on the supporting member and a state in which no thin film is on the supporting member.

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.

A management server receives from a server storing information a request that a data input job be executed and from a data input device a request to assign a data input job to itself. The management server makes a list of information to be digitized through data input, based on information held on itself and input-specific information obtained from the server storing information, and transmits the list to a data input device adequate to the data input job. The data input device selects information as data input preference. The data input device obtains the selected information from the server storing information. Through the data input device, its operator inputs the obtained information as computer-usable data. The input data is transmitted to the server storing information. The management server stores, updates, and manages diverse data about input jobs.

摘要:
A rehabilitating pipe having a flange at one end thereof is laid inside a first existing pipe so that the flange contacts an inner circumferential surface portion of a second existing pipe surrounding a portion where the first and second existing pipes intersect. A flange part of a flanged tubular member is adhesively fixed to the inner circumferential surface of the second existing pipe so that the flange part covers the flange of the rehabilitating pipe and the inner circumferential surface portion of the second existing pipe. A tubular part of the flanged tubular member is adhered to the rehabilitating pipe to thereby seal a gap between an inner circumference of the first existing pipe and an outer circumference of the rehabilitating pipe.

摘要:
A first chopper between a laser device and a semiconductor substrate chops an excitation light at a specific frequency, and a second chopper between the first chopper and the semiconductor substrate chops the excitation light at a variable frequency higher than the first chopper. A photoluminescence light emitted by the semiconductor substrate when the semiconductor substrate is intermittently irradiated with the excitation light is introduced into a monochromator. A controller obtains the decay time constant T of the photoluminescence light from variation of the average intensity of the photoluminescence light when gradually increasing the chopping frequency of the excitation light by controlling the second chopper, and computes the life time &tgr; of the semiconductor substrate from an expression “&tgr;=T/C”, where C is a constant. An object of the invention is to accurately evaluate impurities, defects and the like in a semiconductor substrate by obtaining quantitatively the life time of the semiconductor substrate having a long life time.

摘要:
An ink jet apparatus has installed therein a retractable recovery device. The ink jet apparatus has a housing with a space accommodating a carriage for scanning a recording area, an ink jet head removably mounted on the carriage for ejecting ink onto a recording medium as the carriage scans the recording area, and a removable cover member forming a part of the housing covering said space. The recovery device includes a pressing member mounted in the space at a location outside the scanning area for movement between an accommodating position and an operating position. The pressing member extends from the space when moved to the operating position after removal of the cover member, whereby a recovery operation using the pressing member can be performed on the ink jet head by removing the ink jet head from the carriage. The pressing member, when in the accommodating position, is disposed within the space for concealment by the cover member.
