摘要:
In a light source apparatus, the polarization mode of oscillation light from a semiconductor laser is switchable between two different polarization modes when a modulation current is injected into a portion of a light waveguide of the semiconductor laser. Light in one polarization mode and light in the other polarization mode are separately obtained from the oscillation light from the semiconductor laser. At least the light in one of the two different polarization modes is converted to an electric signal. Current injected into the semiconductor laser is controlled based on the electric signal such that a modulation state of light from the semiconductor laser is stabilized. The light in the other polarization mode, or light in one polarization mode emitted from the other emission side of the semiconductor laser may be used for optical transmission.

In case of forming films in plural positions with an ink jet head having plural nozzles, to provide a method of efficiently correcting an aberration in the liquid droplet applying position resulting for example from a distortion of a substrate, thereby producing an electron source with a high production yield. Positions of device electrodes 2, 3 on the electron source substrate 1 are detected by fetching in advance a surface image of the substrate 1, then a position of an electroconductive film 4 is calculated as a liquid droplet applying position, and an inclination angle θ of the ink jet head 11 is so regulated that a pitch of the nozzles 12 matches a pitch d of the obtained liquid droplet applying positions.

A first light waveguide is formed, and second and third light waveguides are respectively connected to the first light waveguide at first and second positions. A first coupler for effecting tight branching and/or combining is arranged near the first position, and a second coupler for effecting light branching and/or combining is arranged near the second position. An optical amplifier is arranged on the first light waveguide between the first and second positions for compensating for a light loss of a light wave caused by each of the first and second coupler.

An automatic sub-mold changer for use in an injection molding machine having a pair of molds in which sub-molds are detachably installed in an open state of the molds includes a sub-mold stock device for stocking plural sub-molds therein, the sub-mold stock device being spaced from the pair of molds on the injection molding machine. An arm device having an end portion which carries chucks to which the sub-molds are detachably affixed is movable between a first position juxtaposed to the sub-mold stock device and a second position juxtaposed to the pair of molds on the injection molding machine.
摘要:
A plurality of kinds of ink jet devices are used for different regions, respectively. For element electrode pairs arranged in the vicinity of the fixed position of a spacer for example, there is used an ink jet device having an excellent performance in drop placement accuracy, drop volume accuracy or the like. For the remaining element electrode pairs, there are used ink jet devices having an inferior performance. As a result, an electron source substrate of a high quality can be manufactured at a low cost and with a high throughput.
