  • Patent number: 9612449
    Abstract: An axially symmetric polarization conversion element that converts incident light into an axially symmetric polarized beam includes a reflection section having a shape obtained by rotating the cross section of a Fresnel rhomb wave plate along the direction of an optical axis around an axis that is parallel to the optical axis. The axially symmetric polarization conversion element converts the incident light into an axially symmetric polarized beam by utilizing two Fresnel reflections by the reflection section.

  • Patent number: 8825257
    Abstract: An autonomous navigation method is a method of causing a mobile body (100) to autonomously navigate while comparing environmental magnetism data obtained in advance by measuring magnetism generated along a navigation path on which the mobile body (100) navigates and measured magnetism detected by actually measuring the magnetism generated along the navigation path when the mobile body (100) navigates along the navigation path. The method includes a step (a) of detecting first measured magnetism and second measured magnetism in different positions on the mobile body (100) and a step (b) of causing the mobile body (100) to autonomously navigate on the basis of the second measured magnetism detected by a magnetism sensor (103), which is not affected by unexpected magnetism (G) not included in the environmental magnetism data, and the environmental magnetism data.

  • Patent number: 6518706
    Abstract: A continuous or a long-pulsed microwave oscillated from a microwave oscillator 1 is propagated in a waveguided tube 2 in which a given gas is charged. Subsequently, by irradiating a laser having a given intensity from a laser source 4 to the points, A and B in the tube 2, the given gas is partially made plasma. Just then, the microwave can not travel beyond the plasma-part of the given gas and reflects thereat. Accordingly, the microwave is divided at the plasma-part and thereby, a short-pulsed microwave can be obtained.
