Abstract: A method of measuring the azimuth and resetting to zero azimuth automatically is disclosed. Multiple azimuths in longitudinal and latitudinal orientations are sampled by two orthogonal magnetic sensors installed in an azimuth meter, and then are output by corresponding first and second sine wave signals. These two sine wave signals are normalized by adjusting them to be of equal amplitude. The maximum and minimum values of the normalized sine wave signals are used to compute the average values of the respective normalized sine wave signals being of equal amplitude on the positive and negative sides. The resultant sine wave signals serve as the zero reference values for comparison with subsequently taken measuring signals to yield the actual azimuth. The numerical computation for the azimuth can be performed by a microprocessor with accuracy and high speed.

Abstract: The present invention provides a cylindrical slab type gas laser for generating an excellent laser beam having substantially Gaussian intensity distribution of the focussed output laser beam. For this end, a pair of cylindrical electrodes 11, 12 of different diameter are disposed vertically and concentrically. And laser medium is filled in the gap between the two cylindrical electrodes 11, 12 to define a cylindrical straight slab 1. Disposed at one end of the cylindrical top of the cylindrical straight slab 1 is a ring-shaped trick mirror M1 and also disposed at the center of the one end of the cylindrical straight slab 1 is an output mirror M2 to pass a part of the light and to reflect a part of the remaining light. On the other hand, disposed at the other end of the cylindrical straight slab 1 is a w-axicon mirror M3. The above construction eliminates the need for spacers between the two cylindrical electrodes 11, 12 which are required in a conventional gas laser.
Abstract: A multilayered volume hologram structure of the invention comprises a substrate 2 for a certificate or the like, and an adhesive layer 5, a volume hologram layer 5 and a surface protective film 7 laminated on the substrate in the described order. When a multilayer structure consisting of the volume hologram layer 5 and surface protective layer 5 is forcibly released from the substrate for the purpose of making a photograph replacement or falsifying a personal information area, the volume hologram image can break down certainly, thereby ensuring prevention of falsification. A multilayered volume hologram structure-making label is useful for making a multilayered volume hologram structure.

An indicating ring is provided between the exterior disk and the exterior seat. Those outside the door can conveniently know whether the door is locked by observing the indicating ring.
Abstract: An office tool assembly has a tool and a hanging cap. The tool is selectively inserted into and held in the hanging cap. A protrusion is moveably mounted on the tool to engage with a through hole defined in the cap to keep the tool from falling out of the hanging cap. A transverse hole is defined in the hanging cap through which a string extends, such that the tool assembly can be hung around a person's neck. Accordingly, a user can conveniently and safely carry the tool assembly to any desired place for use.

Abstract: The present invention relates to a defect inspection apparatus for a phase shift mask that is capable of detecting phase shifter defects that cannot be detected by conventional inspection techniques, by a simple method using an optical method and a comparison of electric signals. In a defect inspection apparatus for a phase shift mask having a phase shifter pattern provided on a mask transparent substrate 1, after the phase shifter pattern has been formed, a phase shifter defect inspection is performed from the mask transparent substrate 1 side of the phase shift mask 1. To perform the defect inspection, light 12 is applied to the phase shift mask 1 from the mask transparent substrate 1 side thereof, and reflection images of at least two different phase shifter pattern fabricated regions are captured by photoelectric conversion light-receiving elements 15a and 15b.
