An input device includes a substrate and a movable object that moves on the substrate. One of the substrate and the movable object includes a magnetic field generator and the other of the substrate and the movable object includes electromagnetic conversion elements provided to detect magnetic fields generated outside of the magnetic field generator.

Input device

An actuator includes: a magnetic field generator that has different magnetic poles alternately arranged in a plane, with a predetermined position being the center of the magnetic poles; a coil holder that holds a plurality of coils that are radially arranged and face the magnetic field generator, relative motion being caused between the magnetic field generator and the coil holder; and an electromagnetic conversion unit that detects the relative motion and is mounted on either the magnetic field generator or the coil holder.

A tactile panel includes a vibration panel, a yoke provided to face the vibration panel, drive coils secured on a circumference of the vibration panel, and a set of permanent magnets arranged between the vibration panel and the yoke. The vibration panel is held by panel holding members, into which both sides of the vibration panel are inserted in a direction substantially perpendicular to a vibration direction of the vibration panel.

Tactile panel

A disclosed antenna device includes a ground plate, a feeding unit that extends from the ground plate at a predetermined angle for a predetermined length, the feeding unit being prepared perpendicular to the ground plate, and a non-conductive section formed in the ground plate. The shape of the non-conductive section is adjusted according to a desired frequency characteristic.

Antenna device

A disclosed antenna device includes a plate-like ground plate, and a feeding unit that extends from the ground plate for a predetermined length at a predetermined angle. The feeding unit is constituted by a half-body, which is a body, such as a circular cone, halved by a plane perpendicular to the ground plate, and the feeding unit is prepared perpendicular to the ground plate.

A switch operable under a predetermined condition includes a plurality of switch parts each including a pair of reed pieces and a connecting member of an electrically conductive non-magnetic material via which the plurality of switch parts are serially connected. The switch operates only under a condition where all of the plurality of switch parts are operated by external magnetic fields individually and simultaneously acting on the plurality of switch parts.

Switch operable under a predetermined condition, external magnetic field generating unit, combination of such a switch and an external magnetic field generating unit and electronic apparatus incorporating the same

A balanced-armature type polar relay ( ) capable of assuring, by its own structure, sufficient insulation distances, meeting the requirements of IEC60950, when mounted on an electric communication line connecting equipment, wherein a maximum distance between one movable contact and one fixed contact capable of being brought into contact with each other during the travel of an armature is set at 1 mm or more, and at least one of the abutting surfaces of the armature and the core polar surfaces of the electromagnet opposed to the abutting surfaces is formed as an inclined surface to reduce an angle of opposed surfaces at the time of mutual abutment to as little as possible, whereby the armature passes, during the travel thereof, a position where each of the pair of abutting surfaces faces the pair of corresponding core polar surfaces in parallel with each other.
