摘要:
Provided, in parallel to an electromagnetic pump in a power supply system, is an electromagnetic pump compensation power supply mechanism (10) that will perform a power-factor improving function as a synchronous machine during normal operation of a plant. The electromagnetic pump compensation power supply mechanism (10) is provided with an exciter stator permanent magnetic apparatus (45) that can switch an exciter between a non-excited state and an excited state. The exciter stator permanent magnet apparatus (45) comprises exciter stator permanent magnets (15a), springs (16) that apply force to the exciter stator permanent magnets (15a) towards positions facing an exciter rotor winding (15b), and electromagnetic solenoids (20) that make the exciter stator permanent magnets (15a) move to positions not facing the exciter rotor winding (15b) in resistance to the force applied by the springs (16).

A method for producing a range data includes: irradiating a pulse light toward an object during a first time period; receiving a reflected pulse light during the first time period and a second time period; calculating a ratio between a first or second received light amount and a total received light amount, wherein the first received light amount is a light amount received during the first time period, wherein the second received light amount is a light amount received during the second time period, and wherein the total received light amount is a sum of the first and second received light amounts; and producing the range data based on the ratio.
摘要:
First image data including a first pixel value according to the intensity of background light is obtained by means of only exposure. Second image data including a second pixel value according to the intensity of the light reflected or scattered by an object is obtained by so controlling light emission and exposure as to receive part of the reflected or scattered light over the whole exposure period. The part of the reflected or scattered light corresponds to the flat period of emitted pulsed light. Third image data including a third pixel value according to the distance to the object is obtained by so controlling light emission and exposure as to receive the part of the reflected or scattered light for a time according to the distance. The first pixel value is subtracted from each of the second and third pixel values so that the influence of the background light can be excluded. The ratio between the subtraction results is calculated so that the influences of factors that vary the intensity of the reflected or scattered light can be cancelled.

An electrode group is provided in a portable terminal carried by a human body for transmitting a transmission signal to the human body functioning as a transmission medium. The electrode group contains three electrodes arranged respectively at three vertices of an equilateral triangle. Three types of driving electrode pairs are defined as respectively having different combination of optional two electrodes. While changing the driving electrode pairs for use in order one pair by one pair, the transmission signal based on the same transmission data is repeatedly transmitted as many times as the number of driving electrode pairs.

An operation control system includes a transmitter circuit, a transmitter interface, an engine start button switch, a receiver unit and an engine ECU. The transmitter circuit generates a transmission signal and the transmitter interface inputs a communication signal to an operator by converting the transmission signal. The receiver unit receives the communication signal through the operator, when the operator touches the engine start button switch. The engine start button switch detects in-blood alcohol concentration of the operator. The receiver unit generates and applies an engine start control signal in response to output signals of the receiver unit indicative of the operator's engine start operation and alcohol detection result.

A lighting fixture apparatus for a vehicle is disclosed wherein both left and right side lighting fixtures or lamps may not be extinguished simultaneously and maintain a necessary function even if a light source extinguishes due to malfunction of the light source or its control circuit. Two optical transmission devices are provided each of which has a light source, two optical cables connected to both sides of the light source, and flat and hot zone luminous intensity distribution lenses connected to both ends of the two optical cables. The flat and hot zone luminous intensity distribution lenses are distributed to both the head lamps. An illuminating range obtained by combining illuminating ranges wherein both the lenses mounted on one of the optical transmission devices illuminate is similar to an illuminating range obtained by combining illuminating ranges wherein both the lenses mounted on the other optical transmission device illuminate. Thus, even if one of the light sources extinguishes the illuminating range and simultaneous lighting of both the lighting fixtures may be maintained.
