Abstract: An information providing system includes: a processor; and a memory storing instructions that, when executed by the processor, cause the information providing system to perform operations including: acquiring position information indicating a user position; acquiring at least one of pieces of data information, each including sound information representing a sound, range information associated with the sound information and representing a predetermined range on a map, and reproduction information associated with the sound information and indicating settings related to reproduction of the sound in the sound information; and reproducing a sound by referring to the at least one of pieces of data information based on the position information. In a case in which there are one or more pieces of range information representing ranges including the user position, the reproduction processing is executed for each of the one or more pieces of range information.

Abstract: A walking assist device has a frame, a pair of right and left arm portions, a pair of right and left grasp portions, wheels including a pair of right and left drive wheels, drive units, a battery, a drive control unit, acting force measurement units that measure acting forces on the grasp portions, and holding units that hold the grasp portions at a predetermined position in the front-rear direction of the arm portions set in advance. The walking assist device travels forward together with a user. The holding units generate a restoring force for returning the grasp portions to the predetermined position. The drive control unit controls the drive units on the basis of acting forces calculated on the basis of detection signals from the acting force measurement units.

Abstract: A rotor includes: a rotor core fixed to a rotating shaft so as to be rotatable together with the rotating shaft; and a plurality of permanent magnets embedded and fixed in the rotor core. Each permanent magnet is formed of a pair of magnet pieces having a pair of magnetic pole-facing portions radially extending and magnetized so that poles of the same polarity face each other in a circumferential direction. The pair of the magnetic pole-facing portions is formed so that the length of each magnetic pole-facing portion in a magnetization direction is greater in a radially outer portion than in a radially inner portion.

Abstract: An object is to provide an interior permanent magnet rotor unit that allows possible demagnetization to be suppressed regardless of a material for a portion of a permanent magnet, which is positioned on an outward side in a radial direction of a core. A core is a laminate of first thin-plate-like members and second thin-plate-like members. The first thin-plate-like members and the second thin-plate-like members have first insertion slots and second insertion slots each of which is filled with a permanent magnet. In the first thin-plate-like members, a separating portion is formed at an end of each of the first insertion slots or the second insertion slots, which end is located on an outward side of the insertion slot in a radial direction, to form a slit in the corresponding permanent magnet.

Abstract: An interior permanent magnet rotor restrains demagnetization of permanent magnets embedded in a core. Each permanent magnet is formed by joining a first portion and a second portion at a connection. The first and second portions extend from the outer side toward the inner side in the radial direction of the core. The outer end faces of the first and second portions in the radial direction of the core extend in an orientation direction as viewed in section perpendicular to the axial direction. The outside diameter of the core gradually increases from the boundaries between a single magnetic pole and magnetic poles adjoining the single magnetic pole toward the middle of the single magnetic pole in the circumferential direction of the core.

Abstract: A steering control apparatus includes a direct current power source, a three-phase alternating current motor, and a motor driving circuit. An emergency switching element is provided on at least two phases of a three-phase power supply line connected to the three-phase alternating current motor within the motor driving circuit, and the emergency switching element is turned off when an abnormality occurs such that the motor driving circuit is disconnected from the three-phase alternating current motor. The emergency switching element is a MOSFET, and the MOSFETs are provided in pairs in each of the two phases of the three-phase power supply line. Further, parasitic diodes of the pairs of MOSFETs are disposed in opposite orientations to each other.

Abstract: Information is provided by a voice taking users into account. An information providing system provides information using a voice. A position direction acquisition unit acquires position information indicating a position of a user, and sight direction information indicating a sight direction that is a direction that a face of the user faces. A storage unit stores, in advance, object position information indicating respective positions of a plurality of objects that may be viewed by the user, and explanation information for explaining each of the objects. An estimation unit estimates the object being viewed by the user based on the position information and the sight direction information of the user, and the object position information. An information output unit outputs the explanation information of the estimated object using the voice.
