Title: Optical connector ferrule
Inventor: SUEMATSU KATSUTERU
IPC: G02B6/36
Filed: 2002-02-05
Abstract: PROBLEM TO BE SOLVED: To solve a conventional problem in which lack of constant inserting length at a coating part causes various troubles. SOLUTION: This optical connector ferrule is equipped with a fiber insertion hole composed of an introductory hole, an intermediate hole, and minute holes. The introductory hole has a sectional area, which allows insertion of the coated portions of optical fibers. The intermediate hole has a sectional area which does not allow insertion of the coated portions of the optical fibers but which allows insertion of bare fibers exposed in front of the coated portions. Each of the minute holes has a sectional area, which allows individual insertion of each of the forward end portions of the bare fibers inserted into the intermediate hole. Thus, the insertion length of the optical fibers in the fiber insertion hole is uniquely determined. In particular, the insertion length of the coated portions can be set to be a predetermined length easily and reliably.

Filed: 2002-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To suppress an increase in chromatic aberration by a semiconductor exposure device and to efficiently expose a semiconductor wafer.  <P>SOLUTION: When an etalon spectroscope 32 measures the spectrum wavelength of laser light, convolution processing is performed which uses a device function (λ) for the spectrum waveform g (λ) of the incident light. The etalon spectroscope 32, therefore, outputs a spectrum waveform f (λ) after the convolution processing. A data arithmetic part 40 finds an index value of the spectrum waveform g (λ) before the convolution processing according to the spectrum waveform f (λ) after the convolution processing. The spectrum waveform g (λ) of the laser light varies with the laser gas concentration in a chamber 10. When the index value of the spectrum waveform g (λ) before the convolution processing exceeds a threshold, a controller 50 performs gas control so that the index becomes less than the threshold.  <P>COPYRIGHT: (C)2003,JPO
