Abstract: <P>PROBLEM TO BE SOLVED: To reduce scintillation caused by light output from a light source device.  <P>SOLUTION: There is a difference of "d" in the length of an optical path between branch light 301 and branch light 303 obtained by dividing light by a half-mirror array. The optical path "d" is greater than the coherent length of emitted light. Therefore, the length of the optical path of the branch light 303 is made different from that of the branch light 301 by the length equal to or greater than the coherent length and is shifted in phase. The length of the optical path of branch light 312 is made different from that of branch light 311 by "d" and is shifted in phase. In addition, the length of the optical path of branch light 304 is made different from that of the branch light 301 by "2d" and is shifted in phase. The combined light of the branch light 301, 303, 304, 311 and 312 is combined light passed through the plurality of optical paths having differences greater than the coherent length. Accordingly, the combined light is low in coherence and can reduce scintillation.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Filed: 2007-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a protection relay system which can continuously play a role as a protection relay device even in the middle of the replacement of a component by restoring an abnormality region of a failure device.  <P>SOLUTION: When a first device fails, a contact point 12 is closed and a current flows to a coil 25, a contact point 7a is opened, and a contact point 7b is closed. In a second device at a sound side, a blocker can be tripped since AND conditions at contact points 21a, 21b can be established. In this state, when drawing out the first device from an accommodation box for the repair of failure, the contact point 12 disappears, and the contact points 7a, 7b are returned to opening/closing states in the sound time of the first device. A single protection operation becomes impossible in the second device. For this reason, the mechanical component 13 for maintaining a current passage even in a state where the first device is drawn out is arranged at the accommodation box side in order to maintain the passage of a drive current of the coil 25 formed by the closing operation of the contact point 12 even after the first device is drawn out.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2007-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid crystal display device which has high manufacturing efficiency and by which a defect caused by a swelling part of a working end is hardly generated.  <P>SOLUTION: A transparent conductive film is worked in a prescribed shape by irradiating the transparent conductive film on a substrate with laser light (step 201) and the swelling part generated at the end of the transparent conductive film by the working step 201 is removed in a removing step 202. Thereby determination of an irradiation condition is made easy, because the irradiation with laser light can be performed on a condition permitting the swelling part generated at the end of the transparent conductive film in the working step 201. An irradiation condition limiting one prescribed wavelength such as a fundamental wave of a YAG laser can be also determined. Thus a step required for determining the irradiation condition is simplified and since irradiation with laser light of large capacity can be performed, manufacturing efficiency can be improved.  <P>COPYRIGHT: (C)2009,JPO&INPIT
