摘要:
An optical fiber sheet comprises optical fibers sandwiched between sheet members and fixed thereto. Distal ends of the optical fibers extend from outer peripheral edges of the sheet members with resin coatings applied to the distal ends to produce extensions. The distal ends of the extensions are inserted into fiber holes of connectors with the resin coatings applied to the distal ends to be connected with the connectors.

A data recording and reproducing apparatus has facilities for recording and reproducing, inputting and outputting, and editing data and can perform edits by itself. The data recording and reproducing apparatus records AV data inputted from an input port on HDDs by using a recorder and reproducer, and outputs data reproduced from HDDs by the recorder and reproducer through an output port. In an editor inputted is data inputted from outside and data reproduced by the recorder and reproducer. The editor performs edits on at least either of the data above by using a matrix switcher and an audio mixer provided therein. A special effector is utilized as necessary. The editor can output data obtained through editing processing to a switch.
摘要:
A multilayer wiring structure of a semiconductor device having a stacked structure is arranged to restrain reliability degradation due to stress applied to the region of wiring between opposite upper and lower plugs. The rate of overlap of contact surface between upper plug and wiring on contact surface between lower plug and wiring, is small to the extent that no void is generated. The multilayer wiring structure is produced such that no grain boundary is contained in the region of wiring between upper and lower plugs. The difference in thermal expansion coefficient between the material of wiring and the material of upper and lower plugs, is small to the extent that no void is generated.

A substrate processing apparatus includes a photosensor for detecting the presence/absence of a substrate in each place within a carrier cassette, a pair of processing tanks for performing the same process at the same time, and a supply mechanism for supplying a processing solution to the processing tanks independently. The number of substrates is detected in accordance with the result of the detection of the photosensor. If the number of substrates detected is not greater than an allowable number for one of the processing tanks, the processing solution is supplied to only the one processing tank to perform the process. This reduces the consumption of the processing solution in a batch process.

An optical transmission apparatus comprising a first detector for detecting the power of the supervisory signal light separated from received wavelength-division multiplexed signal lights; a second detector for detecting the power of the wavelength-division multiplexed signal lights after the separation of the supervisory signal light; a gain-controlled type optical amplifier for amplifying the wavelength-division multiplexed signal lights; an optical attenuator coupled to the amplifier; and a control unit for controlling the optical amplifier and the optical attenuator so as to keep the output level of the wavelength-division multiplexed signal lights to a predetermined target value, wherein the control unit restrains automatic output level control by the optical attenuator when the supervisory signal light power fluctuates within its permissible range and fluctuations in the signal light power have deviated from its permissible range.

In a process of varying pressure of a pressure container (24) accommodating a forearm (22) of a subject (20) in a pressure range including negative pressure, a diameter (cross-sectional shape value) (D) of an artery 44 in the forearm (22) accommodated in the pressure container (24) is measured non-invasively by a vascular diameter calculating unit (76). In addition, a display controller (display controlling means) (80) operates to display on a displaying device (16) a variation of an internal pressure (Pc) in the pressure container (24) and a variation of the diameter (D) of the artery (44) varying depending thereon. Based on the diameter (D) of the artery (44) obtained in the high pressure region, the variation of the internal pressure Pc in the pressure container 24 and the variation of the diameter (D) of the artery 44 varying depending thereon i.e. mechanical properties of the artery (44) are displayed on the displaying device (16). The artery (44) can be evaluated accurately based on the mechanical properties.
摘要:
In the WDM systems, the OSNR and the signal loss among the optical signals are substantially minimized at the receiving terminal to combat the SRS effects. An equal amount of the signal loss is expected for every span in the transmission path so that the optical amplifier gain tilt is not affected among a number of wavelength frequencies in the optical signal. This is accomplished by controlling the amplification process according to a feedback from the monitoring units for monitoring the optical signal.

摘要:
Umbilics of two surfaces are compared and it is determined from this comparison whether the suspect surface is a copy of the original surface based on the comparison. Comparing umbilics includes determining whether locations of the umbilics of the suspect surface match within a specified margin umbilics of the original surface, and determining whether pattern types of umbilics of the suspect surface match pattern types of corresponding umbilics of the original surface. A “weak” test may be performed, in which corresponding points on the two surfaces are compared, wherein the comparison of umbilics is performed if corresponding points of the two surfaces are located within a specified margin of each other. The points may be gridpoints on wireframes, which in turn may be based on lines of curvature of the surfaces. Comparing umbilics is performed if it is determined that each surface has at least one umbilic. Further still, an “intermediate” test may be performed which includes, for each surface, computing the principal directions of lines of curvature at each grid point. The computed directions of lines of curvature for corresponding gridpoints on the surfaces are compared. A determination is made as to whether the suspect surface is a copy of the original surface, based on the comparison.
