Title: Multiple optical axis photoelectric switch
Inventor: WAKE TORU
IPC: H01H35/00
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a multiple optical axis photoelectric switch, capable of easily adjusting an optical axis without causing a cost increase. SOLUTION: As for this multiple optical axis photoelectric switch, since all light intercepting elements are divided into four groups of light intercepting elements 41-44, and the display parts 31-34 corresponding to them are provided, the number of display parts for adjusting optical axes can be reduced in comparison with a conventional one equipped with a display lamp for adjusting the optical axis for every light intercepting element. Since a laser beam source used in the one with a laser pointer is not separately required, a manufacturing cost can be also suppressed.  In addition, the display parts can be brought close to their normal setting positions step by step by adjusting the optical axes so as to increase the number of lighted display parts among the first - fourth display parts 31-34, and the display modes (light-out, flickering, lighting) are changed in accordance with the added value of an intercepted light signal from the light intercepting element 21 in each group of the light intercepting elements. Thereby, the optical axis can be very easily adjusted in comparison with a conventional one wherein all optical axes must be adjusted at a time.

Title: Arc tube
Inventor: OSHIMA YOSHITAKA
IPC: H01J61/36
Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To aim at prolonging a lifetime by effectively suppressing generation of a leakage caused by peeling off of a molybdenum foil in an arc tube comprised that the both members are joined with a pinch seal in a state that the molybdenum foil is inserted into inside of an arc tube main body made of fused quartz. SOLUTION: This is constituted that a junction of an arc tube body 20 and a molybdenum foil 30 is made so that not less than 105 N/m2 of compressive stress remains along the joint surface o the arc tube body 20 at room temperature. By this, even if the stress is fluctuated on the joint surface due to repeated on-and-off lighting of the arc tube, the compressive stress is always made to be generated in the arc tube body 20 (or even if the compressive stress and tensile stress are alternately generated, the value of the tensile stress is made to be extremely small) so as to increase a junction force of the both members.  Further, plural cracks (grain boundary cracks) are made to be generated on the molybdenum foil 30 by a large pressure acting at a time of pinch sealing, and also by the fact that the fused quartz is made to be inserted into these cracks, the junction force of both members is increased.

IPC: G01J9/02
Filed: 2000-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce a computing error when a Fourier transform is executed to fringe image data to which a carrier frequency is introduced by a method wherein carrier fringes generated due to a relative inclination between a wave front from an object to be observed and a wave front from a reference face can set the inclination so as to become the prescribed multiple of a fundamental frequency decided by shape information on the object to be observed and by an observation means. SOLUTION: An interference fringe image on which the carrier fringes are superposed and which expresses the shape information on the object to be observed is obtained (S1). The Fourier transform is executed to the image (S2). The carrier frequency is extracted (S3). Whether the carrier frequency is at the integral multiple of the fundamental frequency expressing the shape of the object to the observed or not is judged (S4). When the carrier frequency is not at the integral multiple, the inclination of the reference face is found (S5). The drive amount of PZT is adjusted in such a way that the carrier frequency becomes the integral multiple of the fundamental frequency of a fringe pattern which expresses the shape of the object to be observed (S6, S7). This procedure is returned to S1.  When it is judged that the drive amount is at the integral multiple in S4, it is judged that the drive amount of the PZT is adjusted (S8). The shape regeneration processing operation on the surface of the object to be observed is executed (S9).
