In an antenna, a first type radiation electrode and a second type radiation electrode are provided on the surface of a dielectric base, which has a predetermined external shape, or embedded in the dielectric base. The first type radiation electrode is provided with an open terminal at one end thereof and a feeding terminal at the other end thereof so as to constitute a monopole type antenna. The second type radiation electrode is provided with a capacitive-coupling feeding electrode at one end thereof and a ground connection terminal at the other end thereof so as to constitute a capacitive feed antenna. The one end of the first type radiation electrode is located opposite to the feeding electrode of the second type radiation electrode when viewed in the direction of the length of the dielectric base.

The present invention relates to provide a projection exposure device having a small volume, thereby not occupying a large installation space. The projection exposure device is configured to transfer patterns formed on a mask to a surface of film-shaped tape on an upright exposure stage by projecting the patterns onto the surface using light. This projection exposure device includes a transfer mechanism for feeding the tape to the exposure stage vertically, and a projection optical mechanism for irradiating the surface of the tape with the light. The projection optical mechanism is composed of Dyson optics located opposite the transfer mechanism across the exposure stage, and has an optical axis that is substantially perpendicular to the exposure stage.

A radio communication apparatus includes housings that are connected via a hinge unit in an openable/closeable manner, and circuit boards in the housings. The circuit boards are connected via circuit connecting lines functioning as an inductor. One end of the hinge unit is connected to an end portion of the housing and the other end thereof is connected to a portion located farther inside than an end portion of the housing. When the housings are unfolded, a region extending from the portion to the end portion of the housing overlaps a region near the end portion of the housing in a projection domain. A high dielectric member is provided in this overlapped region, and a capacitor is constituted by the high dielectric member and ground areas.

The present invention relates to an exposure device for transferring circuit patterns of a mask to a roll-film-shaped object. The exposure device includes a supply reel rotation section that is constituted by a supply reel around which the object is wound and that feeds the object by rotating the supply reel, at least one guide roller for guiding the object fed from the supply reel rotation section, an exposure stage on which the circuit patterns are transferred to the object guided by the guide roller, and an alignment mark forming section which forms, on the object, alignment marks that are used to align the mask with the object and which is positioned between the guide roller and the exposure stage.

A data recorder for vehicle compares a difference between previously acquired data and presently acquired data with a data threshold value which is set to every abnormal occurrence for a time-series data recorded temporarily in RAM, and determines whether the data is recorded in a data recording device, when various types of data associated with the abnormal occurrence is recorded. Specifically, if it is necessary to record the data with a fine accuracy, a setting of the threshold value for the data is made small, and if it is necessary to record the data with a coarse accuracy, a setting thereof for the data is made large. Accordingly, the data recording accuracy is appropriately set in correspond with the abnormal occurrence, therefore, the cause of the abnormal occurrence is ascertained later without using a recording capacity wastefully.
摘要:
An antenna structure including a dielectric base member provided in a non-ground region of a circuit board and a feed radiation electrode provided on the dielectric base member. An outer side surface of the dielectric base member along an edge of one end of the circuit board defines a side surface. A feed electrode is provided in the non-ground region of the circuit board or outside the circuit board such that the feed electrode is disposed along side surfaces of the dielectric base member. One end of the feed radiation electrode defines a feed end connected to the feed electrode, and the other end of the feed radiation electrode defines an open end. The feed radiation electrode has a configuration in which a current path extending from the feed end to the open end has a loop shape so as to be provided on at least the side surface and an upper surface of the dielectric base member. A feed radiation electrode portion formed on the side surface of the dielectric base member 6 forms a capacitance between the feed radiation electrode portion and the feed electrode for improving antenna characteristics.

A picture display system having two display devices and a base device for supplying picture signals to one of the display devices and capable of having bidirectional communication with the other display device is disclosed. The picture display system (1) is made up by a mobile display device (100), a base device (200) and a large format display device (300). The base device (200) sends picture signals to the display device (100) and to the large format display device (300). On a display image surface of the mobile display device (100), there is provided a touch panel for detecting the contact position contacted by a user for displaying a remote-control panel RP accepting an operating input from the user on the display image surface. An operating signal conforming to a display item of the remote-control panel RP, displayed at a contact position, detected by the touch panel, is generated and transmitted by wireless communication to the base device (200). This base device (200) selects the picture signals, supplied from the external inputting devices (400), as a supply source of picture signals, responsive to an operating signal, to transmit the so selected picture signals to the large format display device (300).

In a magnetoresistance thin film magnetic head, a bias conductor and a magnetoresistive magnetic sensing section are electrically connected to each other in series. Further, the bias conductor (7) is formed in such a pattern as to have a width and distance from a magnetic recording medium facing surface which become larger as it is away from a portion transversing the magnetoresistive magnetic sensing section.
