Abstract:
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.
Abstract:
A communication device is disclosed which is comprised of: a transmitter for transmitting an ultra wide band wireless wave pulse; multiple receivers which are disposed equidistant from the transmitter and receive the ultra wide band wireless wave pulse; and distance-measuring equipment which detects a distance or a direction to an object by measuring time intervals between the first reception times when receivers receive the ultra wide band wireless wave pulse directly from the transmitter and the second reception times when the receivers receive a object-reflected wave of the ultra wide band wireless wave pulse.
Abstract:
In a coreless motor, a shaft of the coreless motor does not pass through a magnet but is arranged in series with a columnar magnet on the same axis. The magnet is inserted in a tubular frame made of magnetic material and a coil which is mounted on the shaft is inserted in the gap between the outer surface of the magnet and the inner surface of the frame.
Abstract:
A structure of the plasma treatment apparatus is employed in which an upper electrode has projected portions provided with first introduction holes and recessed portions provided with second introduction holes, the first introduction hole of the upper electrode is connected to a first cylinder filled with a gas which is not likely to be dissociated, the second introduction hole is connected to a second cylinder filled with a gas which is likely to be dissociated, the gas which is not likely to be dissociated is introduced into a reaction chamber from an introduction port of the first introduction hole provided on a surface of the projected portion of the upper electrode, and the gas which is likely to be dissociated is introduced into the reaction chamber from an introduction port of the second introduction hole provided on a surface of the recessed portion.
Abstract:
There is provided a pressure sensitive switch including: a cover; a slide portion that is stored in the cover and is slidable by being pressed in a horizontal direction; a pressing unit including a pressure portion that has an inner side face brought into contact with the slide portion and can be moved by being pressed by the slide potion; a sheet resistive body that has an upper face brought into contact with the pressing unit; and a conductive plate that is disposed on the lower side of the sheet resistive body with a predetermined gap arranged therebetween. The slide portion is slidable within a horizontal plane, and the pressing portion presses the sheet resistive body by sliding the slide portion, and a resistance value between the sheet resistive body and the conductive plate changes in accordance with a change in a slide operation force for sliding the slide portion.
Abstract:
An actuator including a motor, case, resin mold, connector terminal, and two power supplying terminals. The motor includes two power receiving terminals. The resin mold is arranged in the case at a location close to one end. Each power supplying terminals includes a first extension, which is formed in a distal portion and includes a bent portion, and a second extension, which extends upward or downward from the bent portion. Each second extension includes a contact portion that elastically contacts the corresponding power receiving terminal in a direction in which an axis extends. The contact portions are located at positions that differ between the two power supplying terminals in a vertical direction. In the two power supplying terminals, the bent portions are located at different positions in the vertical direction. Further, the first extensions have different lengths from the resin mold.
Abstract:
A magnetic detector includes a detecting section having a surface facing a magnetic body which moves and emits a magnetic flux. The detecting section includes plural magnetic sensors for detecting the magnetic flux. The magnetic sensors are arranged in a matrix form having three or more rows and three or more columns arranged along the surface of the detecting section. The magnetic detector provides an input device precisely detecting a moving direction and a moving amount of the magnetic body.
Abstract:
A rotary actuator includes a roller having a center shaft protruding along a center axis, a bearing for supporting the center shaft of the roller to allow the roller to rotate about the center axis, a ring magnet fixed to the center shaft of the roller, an elastic member having a ring shape provided between the center shaft of the roller and the bearing, and a fixed magnet facing the ring magnet. The ring magnet is alternately magnetized to an S-pole and an N-pole with predetermined angular intervals. This rotary actuator has a simple structure and operates with a preferable operation feeling.
Abstract:
An automatic adjustment system that includes: a transmission device that includes a constant voltage output unit that outputs a constant-voltage signal to a cable; and a reception device that includes a voltage detecting unit and a control unit. The voltage detecting unit receives the constant-voltage signal transmitted through the cable and detects the voltage of the signal, and the control unit determines signal attenuation based on the voltage detected by the voltage detecting unit and adjusts the gain of a receiving unit that receives the signal from the transmission device. This automatic adjustment system performs gain adjustment on the receiving unit when a cable insertion/pull-out sensing unit senses that the cable is connected to a connector.
Abstract:
A routing guide system includes route calculating means for calculating the route of a vehicle to a destination, image providing means for reading from storage means scenery images on the route calculated by the route calculating means, and display means for displaying the scenery images on the calculated route generated by the image providing means. The routing guide system also includes route confirming means for confirming as a set route the route calculated by the route calculating means, according to an operation, during or after display of the scenery images on the calculated route by means of the display means.
