  • Publication number: 20200300630
    Abstract: The present invention reduces measurement time. A gyroscope of the present invention includes a planar ion trap part, a microwave irradiation part, a laser irradiation part and a measurement part. The planar ion trap part includes two rf electrodes and two DC electrode rows, and forms ion traps that trap one ion on a substrate, a normal direction of the surface of the planar ion trap part corresponds to a z direction. The rf electrodes are disposed in the x direction on the substrate at a predetermined interval. The DC electrode rows are disposed in the x direction on the substrate so as to sandwich the two rf electrodes. The DC electrode rows each include at least five DC electrodes in the x direction. The trapped ions are spaced so as not to interfere with each other. The microwave irradiation part irradiates the ions with ?/2 microwave pulses.

  • Publication number: 20200256677
    Abstract: A gyroscope includes an atomic beam source to generate an atomic beam in which individual atoms are in the same state, a moving standing light wave generator to generate M moving standing light waves, an interference device to obtain an atomic beam resulting from the interaction between the atomic beam and the M moving standing light waves, a monitor to detect angular velocity by monitoring the atomic beam from the interference device and an accelerometer. The accelerometer acquires information on acceleration applied to the gyroscope and the moving standing light wave generator adjusts the drift velocity of at least M?1 moving standing light waves among the M moving standing light waves in response to the acceleration information.

  • Patent number: 6796559
    Abstract: In an automatic document feeder for use in an image forming device such as copy machine and facsimile machine: a document shunting path for temporarily shunting a document is provided at an upstream side of a document reading portion; in a different-size mixed mode where different sizes of documents are placed in a mixed manner, the leading edge and rear edge of the document are detected by a sensor during conveyance of the document in the direction toward the document reading portion, so that the length of the document is detected; thereafter the document is conveyed in the reverse direction so that the rear edge of the document is shunted into the document shunting path; and thereafter the document is again conveyed in the forward direction to conduct reading. Thus, it becomes unnecessary to provide a longer conveyance path for detecting the length of the documents, so that the size of the feeder itself can be reduced.
