Abstract: A tableting punch or a die includes a base material and a tableting surface layer on the base material. The tableting surface layer includes crystalline yttrium oxide containing nitrogen and a group 4A element.

Abstract: A method of determining a route includes searching for an initial route as a guidance route from a departure place to a destination, designating an avoidance route as an unfavorable route for a passage of a user, and in a case where the avoidance route is included in the initial route, outputting a changed route obtained by changing the avoidance route included in the initial route to another route.

Abstract: A translucent material according to this invention includes a base made of a glass-based material, and an oxide layer layered in an upper direction (or on an upper surface) of the base. Examples of the base may include tempered glass using soda lime glass or aluminosilicate glass, heat-resistant glass mostly using borosilicate glass, and quartz glass. The oxide layer includes yttrium oxide (Y2O3) as a base material thereof and further includes nitrogen and a Group 4A element. The translucent material having such a composition is qualified to constitute a low-adhesion material and a molding member. When quartz glass is selected and used as the base material, an intermediate layer may be interposed between the base and the oxide layer.

Abstract: A navigation device includes a display unit, an operation detection unit configured to detect a predetermined random display operation in the navigation device, and a display controller configured to make the display unit display one search theme-specific route among a plurality of search theme-specific routes searched by an internal or external route search unit. The display controller switches a route displayed on the display unit to another search theme-specific route among the search theme-specific routes each time the predetermined random display operation is detected by the operation detection unit.

Abstract: A navigation apparatus includes: a search area setting unit configured to set a search area the search area being an area surrounded by a boundary line input by a user on a map screen displayed on a display unit; a posting message acquisition unit configured to acquire a posting message relevant to a point within the search area from a social networking service; and a display controller configured to display the posting message on the map screen so as to be associated with the point relevant to the posting message within the search area.

Abstract: A linear vibration actuator for which the positional accuracy of coils in the casing can be easily increased. A linear vibration actuator (1) in which a magnet (13) and a weight (15) are fixed. The magnet (13) and the shaft (20) form a magnetic circuit within a casing (2) causing reciprocating motion of the weight (15) and magnet (13), via a coil (24) within a casing (2). The linear actuator (1) includes a shaft (20) provided within the casing (2) and made from a magnetic material. A coil (24) is supported by the shaft (20) includes first and second coil parts (22, 23) arranged parallel to an axial line L and wound in opposing directions. A ring-like magnet (13) surrounds the coil (24) and the shaft (20). A weight is fixed to the magnet. A plate spring (17) biases the magnet (13) and the weight (15) along the shaft (20).

Abstract: A physical activity assistance apparatus includes a blood oxygen concentration measurement section (biological information detection section and blood oxygen concentration calculation section) that measures a user's blood oxygen concentration and a breathing instruction section that instructs the user to practice a predetermined breathing method when the blood oxygen concentration is lower than or equal to a first threshold. The thus configured physical activity assistance apparatus can appropriately support the user's physical activity.

Abstract: According to the present invention, a substituted aromatic compound represented by the following general formula (I) is provided. In general formula (I), A1, A2, and A3 each independently represent an aryl group substituted by a hydrophilic group.
