Title: Formation of polarization inversion grating and optical waveguide
Inventor: MAKIO SATOSHI
IPC: G02B6/13
Filed: 1993-08-10
Abstract: PURPOSE:To generate SHG light with high efficiency by realizing the ideal polorization inversion grating of a rectangular shape. CONSTITUTION:A proton exchange region 16, the polarization inversion grating 12 extending outside this region and an optical waveguide 13 are simultaneously formed by a proton exchange treatment on an LiTaO3 substrate 11. A grating pattern mask is first formed on the front surface of this substrate and a metallic film over the entire rear surface thereof. The substrate is subjected to the proton exchange treatment at >=50 deg.C/min temp. gradient at the time of the treatment and >=50 deg.C/min temp. falling speed from the treatment temp. to form the proton exchange region 16 and the polarization inversion grating 12 extending outside this region. An aluminum nitride ceramic plate is used for a substrate holder of this time to electrically insulate the substrate 11. The refractive index of the proton exchange region 16 is thereafter increased by the heat treatment. The optical waveguide is thus easily realized by one time of photolithography and the SHG element having the high efficiency is realized.

IPC: E04B1/00
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To improve the safety by providing a guide means which is attached to a horizontal beam to vertically move the horizontal beam along a vertical pipe of a scaffold. SOLUTION: The position of arms 25 with respect to a horizontal beam 21 of a tool 20 is adjusted corresponding to the intervals of steel pipes of a scaffold formed outside a building frame and the distance between the building frame and the scaffold to fix the arms 25 to the beam 21 by means of bolts 26 and nuts. Next, a jig 23 of the tool 20 is fixed to an anchor nut opened at the upper end of a panel 1 and upper side wires 22 are connected to a hook of a crane using a chain block 1. The hook of the crane is brought close to the scaffold to engage pulleys 27 of the arms 25 with the steel pipes of the scaffold and the panel 1 is lowered along the steel pipes, while the pulleys 27 are caused to roll with respect to the steel pipes. Since the beam 21 is supported by the scaffold through the pulleys 27, even if the panel 1 is lowered, it does not vibrate and safety can be improved.

Title: Laser beam machine
Inventor: MOKUTA SATORU
IPC: B23K26/064
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in the energy density by measuring the thermal expansion of a laser beam rod, and moving the position of the optical system to correct the diameter of the laser beam due to the thermal expansion. SOLUTION: A displacement sensor 51 measures the diameter of a YAG rod and outputs the signal 51s. A displacement sensor 52 measures the whole length of the YAG rod and outputs the signal 52s. A power meter 53 takes a part of the laser beam by a reflection mirror, and measures the energy density of the laser beam to output the signal 53s. A control device 55 receives the signals 51s, 52s, 53s, judges the thermal expansion of the YAG rod, and detects the spread of the laser beam. Though control can be performed even by using either of the signals 51s-53s, the result will be corrector if all signals are used. The control device 55 outputs the drive signal to a stepping motor 38, and moves a lens by the prescribed quantity. The energy density of the laser beam can be prevented from being reduced. Inconvenience of blurred marking can be prevented.  The cooling condition of the YAG rod and the temperature change in the periphery thereof can be immediately cope with.
