摘要： An optical sending apparatus of this invention includes a plurality of optical signal generating sections, a dispersion compensating section and a wavelength multiplexing section. The dispersion compensating section performs compensation with a predetermined chromatic dispersion value to at least one of polarized light generated by the optical signal generating sections while a predetermined state of polarized light is maintained. The wavelength multiplexing section combines output light outputted from the optical signal generating section with output light passing through the dispersion compensating section so that the polarized light of adjacent wavelengths crosses orthogonal to each other. The optical sending apparatus having such a construction can generate high-density WDM optical signals, the dispersion of which is compensated in advance, by a polarization crossing method.

摘要： A transfer rack 15 loaded with a seriate number of component supply cassettes 14 to be handled collectively is carried and retained on a truck 61 so that it can be taken in and out of the truck 61. The transfer rack 15 is passed between the truck 61 and a component supply section 8. Thus, the withdrawal of the transfer rack 15 from the component supply section 8 to the truck 61 and the delivery of the transfer rack 15 to the component supply section 8 are executed in a timely manner so as to change the component supply cassettes 14 at the component supply section 8. The transfer rack 15 delivered to the component supply section 8 is positioned by operating an automatic positioning means at the component supply section 8 in a direction in which it is loaded and unloaded and in a direction perpendicular to the direction in which it is loaded and unloaded.

摘要： There are provided a wavelength dispersion compensating method of reducing distortion of a transmitted waveform due to cross phase modulation in an optical transmission path, and an optical transmission system utilizing the method. To this end, the wavelength dispersion compensating method of the present invention sets the wavelength dispersion characteristic of the optical transmission path such that the time delay amount to occur between light signals of adjacent two wavelengths due to wavelength dispersion such as in one repeating section in the transmission path, to become ½ times of a bit interval, for the optical transmission path having transmission loss. In this way, one of the light pulses of adjacent two wavelengths is delayed from the other by 1 bit after the transmission of two transmission sections, so that the red chirping to occur in a first repeating section and the blue chirping to occur in a second repeating section offset to each other, resulting in reduction of waveform distortion caused by cross phase modulation.

摘要： A clutch control apparatus includes a clutch disk, which is engaged with a flywheel, by means of a diaphragm spring; a release mechanism (including a rod and an electric motor) for pressing a central portion of the diaphragm spring; and a clutch control circuit. The clutch control circuit calculates an ideal clutch load and an output torque of the electric motor for a detected stroke of the rod. On the basis of these values, the clutch control circuit obtains the acceleration of the rod. The clutch control circuit estimates a stroke of the rod from the obtained acceleration and causes an adjust wedge member to rotate such that a detected actual stroke and the estimated stroke become equal, thereby modifying the attitude of the diaphragm spring accordingly.

摘要： A screen printing method and apparatus for printing a circuit pattern corresponding to that of a stencil (4), onto a print-object article (1) placed on an ascendable/descendable positioning stage (2), through moving a squeegee (5a,5b) horizontally while the squeegee is pushed in on the stencil so that print paste (9) is printed to the article via the stencil. The squeegee is lifted to an extent of a push-in stroke, to which the squeegee has been pushed in on the stencil, and thereafter the article is separated away from the stencil by moving the stage downward. The board is classified into first and second areas (121,120) where values of opening sizes of the stencil along a squeegee moving direction are smaller than and not smaller than a threshold, and a speed of the squeegee at the first area is made slower than that at the second area. Upon an occurrence of print standby time during a printing operation, the print standby time is measured, and at a resumption of printing with the print standby canceled, the paste placed on the stencil during the standby time is screen-printed, by moving the squeegee at an adjusted print speed lower than the reference print speed based on a relationship between the print standby time and a print time due to the adjusted print speed after the resumption of printing.
