  • Publication number: 20200347789
    Abstract: In an aircraft gas turbine engine equipped with a bleed-off valve that bleeds intake air compressed by a compressor exterior and an electric actuator that drives the valve when current is supplied, a required valve opening ?r and a current value Ia corresponding thereto are calculated and Ia is supplied to the actuator to bring valve opening ? to the required opening ?r. Then Ia is compared with a current value Ib and if Ia exceeds 1b, the valve is estimated to have failed and another current value Ic is calculated and Ic is supplied to enlarge valve opening toward wide-opening ?w. Then a current value Id is calculated and supplied to decrease valve opening toward ?r. Next, Id is compared with Ib and the valve is determined normal when Id is equal to or smaller than 1b. If not, it is determined to be faulty.

  • Patent number: 10021269
    Abstract: A read sensor generates front side image information indicating an image on a front side of an object to be read, and front side measurement information indicating a line of an image in a main scanning direction on the front side of a correction chart. A read sensor generates back side image information indicating an image on a back side of the object to be read, and back side measurement information indicating a line of an image in the main scanning direction on the back side of the correction chart. The image correction device calculates an amount of misalignment of read positions based on the front side measurement information and the back side measurement information, and corrects misalignment of images on the front side and the back side of the object to be read, indicated by the front side image information and the back side image information.

  • Patent number: 9602068
    Abstract: A configuration is provided with: a tuned line 13 that is connected between a branch terminal 3 and a branch terminal of branch lines 2 and 4; and a tuned line 14 that is connected between a combining terminal 7 and a combining terminal 9 of combining lines 10 and 11. This enables reduction of a non-uniform voltage distribution occurring due to a difference in characteristics between two amplifier elements 6 and 8.

  • Patent number: 9531903
    Abstract: An image sensor (100) comprises a lens (4), a sensor (6) and a first casing (1). The lens (4) is configured to focus light irradiated toward an object to be read (30) from a direction tilted relative to the X-Z plane, and reflected by the object to be read (30). The sensor (6) is configured to receive the light focused by the lens (4). The first casing (1) is configured to contain or retain the lens (4) and the sensor (6) and to have, in a surface (1j) extending along a main scanning direction, a tilted portion having a length in a sub-scanning direction that decreases toward the object to be read (30).

  • Patent number: 9385150
    Abstract: An image sensor and image sensor device include: a lighting portion extending in a main scanning direction and emitting light to the object-to-be-read; a rod lens array for imaging light from the object-to-be-read; and a light receiving portion for converting the light imaged by the rod lens array to an electric signal. The lighting portion emits a normally directed light from the normal direction of the object-to-be-read to irradiate a first irradiation region of the object-to-be-read, and an inclined light inclined by a predetermined angle from the normal direction of the object-to-be-read to irradiate a second irradiation region being apart from the first irradiation region in a sub-scanning direction.
