Abstract: An information storage device has small compartments for storing information in a solid body and can be used as a memory medium. The solid body can have at least one pair of parallel planar portions on its surface. The information is divided into bits and stored in discrete minute areas that are distributed three-dimensionally inside the memory medium. The data can be converted into a digital format for storage to regulate the number of ‘1s’ recorded in a direction of the memory medium.

Abstract: Exemplary embodiments of the present disclosure relate to providing an optical apparatus that is capable of acquiring representative Raman spec trams with high reliability from hyper spectrum images of samples. An optical apparatus according to this disclosure: receives a specifying input that specifies a specific Raman spectrum bandwidth as a reference signal; and extracts a Raman spectrum for a measurement point where an intensity of the reference signal is at or above a reference intensity.

Abstract: A bogie for a railway vehicle 1 includes an elastic element 20 that is arranged between a vehicle body 7 and a bogie frame 3 of a railway vehicle and elastically supports both, and the elastic element 20 is configured in such a manner that a spring constant for displacement in the longitudinal direction in the traveling direction of the vehicle body 7 is smaller than that for displacement in the vertical direction or the left-and-right direction in the traveling direction.

Abstract: It is an object of the present invention to improve visibility for observation with naked eyes or for camera shooting without spoiling the appearance during marking inside a. transparent medium using a laser. By irradiating an inside of a transparent medium with a laser, the present invention forms a micro-denatured region in each of a first layer and a second layer inside the medium. The micro-denatured regions in the respective layers are arranged out of alignment with each other on a two-dimensional plane (refer to FIG. 1).
