An electromagnetic lens device includes an electromagnetic lens for transmission, an electromagnetic lens for reception, two primary radiators each located at a focal point of one of the electromagnetic lenses, an arm holding the primary radiators, and a table. The arm is rotatable about a first axis that extends through the centers of the electromagnetic lenses. The table is rotatable about a second axis that is perpendicular to the first axis. The primary radiators rotate about the first axis together with the arm, and rotate about the second axis together with the table.

A fraud detection device 10 is provided at a table 1, and it detects a fraud in a card game that is played on the table 1. The fraud detection device 10 obtains entering card information to identify an entering card that is a card entering each game. The entering card information is stored while a game is being played. The fraud detection device 10 also obtains leaving card information to identify a leaving card that is a card leaving a game. Whether an entering card and a leaving card are identical or not is judged by comparing the entering card information and the leaving card information. The judgment result is outputted using an indicator. A fraud in a card game can be detected on the spot.

A voltage between both terminals of each unit battery is amplified by a differential amplifier and is then converted by a converter into a predetermined physical quantity that corresponds to the voltage between both terminals of the unit battery. The converted physical quantity is then level-shifted by a detection circuit and is converted into a voltage on a reference potential of the lowest electric potential of the battery assembly. A control unit sequentially selects the converted voltages by a multiplexer, generates serial digital signals by an A / D conversion, and then transmits the serial digital signals to a control operation unit via an isolation buffer circuit. It is, therefore, possible to provide a battery voltage measurement circuit capable of measuring a voltage of each of unit batteries constituting a battery assembly with high accuracy by using a common measurement circuit in a relatively simple and inexpensive configuration.

A card reading device comprises a rail (18) for guiding a card; card sensors (46, 48, 50) for detecting a passing card which is slid by hand and guided by the rail (18), which are placed in a card sliding direction with a certain gap; and reading sensors (52, 54) for reading code attached to the card, which are placed between the two card sensors in the card sliding direction. The card have the cord which is printed in UV-luminous ink on the card, and the code comprises at least two code rows which are placed across the card sliding direction with a certain gap. The two reading sensors (52, 54) are placed in positions which correspond to the gap of the two code rows, and the card sensors (46, 48, 50) output signal for detecting a position of the passing card.

A horizontal axis wind turbine includes: a yaw sensor; a rotor rotating around a rotor axis extending in a substantially horizontal direction, the rotor axis rotating in a substantially horizontal plane depending on wind direction; a plate-like member disposed on a rotational central portion of the rotor and extending in a parallel direction to the rotor axis and in a vertical direction; two anemometers disposed at positions which are across the plate-like member; and a controller for yaw control based on a difference or a ratio between wind speeds measured by the two anemometers.

A power supply device includes a DC-DC converter configured to regulate an output voltage based on an externally input instruction, and a discharge circuit connected to an output capacitor of the DC-DC converter, wherein the discharge circuit includes a switch element configured to switch between a conductive state and a nonconductive state according to an instruction, and a capacitor-resistor (C-R) circuit configured to charge electric charge accumulated in the output capacitor of the DC-DC converter when the switch element is conductive and to discharge the electric charge to ground when the switch element is nonconductive.

A position detection apparatus comprises a sensor unit 80 and a moving holder 81 and a holder drive portion 82. The sensor unit has a plurality of pairs of sensors, each of which includes a light emitting portion held on the first holding surface 81a and a light receiving portion held on a second holding surface 81b as a pair and which are arranged along sheet width direction, and the sensor unit detects the edge position of the sheet S while the holder drive portion moves the moving holder in the sheet width direction and every other light emitting portions in the plurality of pairs of sensors is turned on.

At least two code rows are printed in UV-luminous ink on a surface of the card on which a mark of the card are printed. The codes 44 and 44 correspond to the mark. A space between the two code rows is provided in a direction which across a reading direction of a cord reader. For example, code 44 represents suits (spades, hearts, diamonds, and clubs), and code 46 represents ranks (numerals 1 to 10, J, Q, and K).

A radiation sensor of the type having a packaged radiation source and detector, which includes an isolator that blocks propagation within the package of radiation from the source to the detector, in order to improve signal to noise ratio of the sensor. The isolator is formed by appropriately formed surfaces of the package.

Provided is a sheet conveying apparatus which conveys a sheet, includes: a sheet conveying path which diverges into a first conveying path and a second conveying path at a diverging point; a guide member which is movable between a first position where the guide member guides the sheet to the first conveying path and a second position where the guide member guides the sheet to the second conveying path; a driving portion which is configured to move the guide member to the second position from the first position; and a holding portion which, in a case that the guide member is driven by the driving portion to move to the second position from the first position, provides a load to the driving by the driving portion and holds the guide member at a third position between the first position and the second position.
