Abstract: A communication terminal includes an acceleration sensor, a position acquisition antenna, a communication interface, and a processor. The processor transmits acceleration information acquired using the acceleration sensor and present position information acquired using the position acquisition antenna in a normal operation mode via the communication interface. The processor changes to an abnormal state when detecting a vibration equal to or higher than a first predetermined value using the acceleration sensor, and increases a frequency of acquisition or transmission of the acceleration information or the present position information in the abnormal state.

Abstract: The present invention enhances instant readability by causing a driver to visually recognize, without a feeling of stranger an image obtained by photographing an area around a vehicle. A display section (11, 12, 13) is provided ahead of a driver, and the display section displays an image, obtained by photographing an area around an automobile (1), so that the image is recognized to be located on a deeper side away from the driver, an amount, by which a visible object is recognized to be located on a deeper side than a display screen, corresponding to a distance which causes the driver to recognize the visible object reflected by a mirror.

Abstract: An aspect of the present invention provides a display device that does not hinder driving. An electronic mirror includes: an image display device capable of switching between 2D display and 3D display, the 3D display being carried out by a parallax barrier method; and a distance measuring device for measuring a distance from eyes of a user to a display screen of the image display device. The electronic mirror switches display from the 3D display to the 2D display in a case where the distance measured by the distance measuring device falls outside a predetermined range during the 3D display.

Abstract: An aspect of the present invention provides a display device that does riot hinder driving. An electronic mirror in accordance with an embodiment of the present invention includes: a depth adjusting section for adjusting a depth of a visible object contained in an image, in a case where 2D display is switched to 3D display or in a case where 3D display is switched to 2D display; and an output image generating section for generating an image which reaches, in a predetermined time period, the depth having been adjusted by the depth adjusting section.

Abstract: On a surface of a film base material (22), an antireflection structure configured by nano-sized optical projections (23) to suppress reflection of light and protective pillars (24) to prevent the optical projections (23) from being flattened out are arranged. The protective pillar (24) has a truncated cone shape. When a diameter of the protective pillar (24) at a proximal end thereof, a height of the protective pillar (24), and an angle between a side surface of the protective pillar (24) and a central axis of the protective pillar (24) on a section passing through the central axis of the protective pillar (24) are given by D, H, and ?, respectively, these values satisfy a relationship: D>2H×tan(2?).

Abstract: An electromagnetic relay is provided with an iron core (50) which has a virtually J-letter shape on a plan view with one end serving as a support-receiving portion (51) and the other end serving as a magnetic pole portion (52), and a movable iron member (60) which is supported by a movable contact member (70) attached to a corner thereof, and has a virtually L-letter shape on a plan view with one end (61) being supported on the support-receiving portion (51) of the iron core (50) so as to freely pivot thereon and an adsorb portion (62) that is the other end being allowed to face the magnetic pole portion (52) of the iron core (50) so as to be adsorbed thereon. The objective of the present invention is to provide an inexpensive electromagnetic relay which is less susceptible to deviations in the adsorb portion of the movable iron member that comes into contact with and separates from the magnetic pole portion of the iron core, and has stable operation characteristics.

Abstract: A thin film of ferrite for use as a magnetic recording medium includes (a) Cu and Ti or (b) Cu, Ti and Co. The inclusion of Ti extends upwards the upper limit of the range of temperature for reducing .alpha.-Fe.sub.2 O.sub.3 to Fe.sub.3 O.sub.4, whereas the inclusion of Cu extends downwards the lower limit of this range. Further, the inclusion of both Ti and Cu enables the stable production of .gamma.-Fe.sub.2 O.sub.3 over a wide range of temperature for oxidizing Fe.sub.3 O.sub.4 to said .gamma.-Fe.sub.2 O.sub.3. The inclusion of Co improves the magnetic properties of the ferrite.

Abstract: A thin film of ferrite for use as a magnetic recording medium includes up to ten atomic percent of Nb based on the total number of metallic atoms in the ferrite film. This thin film of ferrite further includes up to fifteen atomic percent of Cu in addition to the Nb. The inclusion of Nb improves the squareness ratio and the coercive force of the recording medium, and also enlarges the temperature range of reduction from .alpha. -Fe.sub.2 O.sub.3 to one of the ferrites, i.e. Fe.sub.3 O.sub.4. The inclusion of Cu lowers the reduction temperature below 300.degree. C. According to the invention, a magnetic recording medium exhibiting excellent required properties, such as a high coercive force and a high squareness ratio, can be produced by a reliable process.

Abstract: A thin film of ferrite for use as a magnetic recording medium contain (a) Cu, (b) both Cu and Co, or (c) Cu, Co and Nb. The inclusion of Cu increases the temperature range for reduction from .alpha.-Fe.sub.2 O.sub.3 to one of the ferrites, i.e. Fe.sub.3 O.sub.4, and also lowers the above-mentioned reducting temperature. The addition of Co improves the magnetic properties of the ferrite. The simultaneous addition of Cu, Co and Nb provides .gamma.-Fe.sub.2 O.sub.3 with excellent magnetic properties, which are stable over wide temperature range for oxidizing the Fe.sub.3 O.sub.4 to the .gamma.-Fe.sub.2 O.sub.3.
