  • Publication number: 20160207563
    Abstract: A malfunction detection device for a resolver detects malfunction in a resolver with accuracy and stability even if a value of a square sum is varied between inside and outside of a normal range. When the resolver is in malfunction, a sine signal and a cosine signal are read. It is determined whether a malfunction determination of the resolver is prohibited, or not, from read values of the sine signal and the cosine signal, or square values thereof. When it is determined that the malfunction determination of the resolver is prohibited, the count value is accumulated and incremented every time the test value falls outside a normal range. When the count value arrives at a given value or higher, it is determined that the resolver is in malfunction.

  • Publication number: 20160133079
    Abstract: An image processing method corrects an image acquired from a medium exposed to ultraviolet light and makes parts printed with UV ink easily recognizable. A control device acquires a first image captured by an image sensor from a check exposed to visible light, and acquires a second image captured by the image sensor from the check when exposed to ultraviolet light. The control device generates a first edge image by applying an image processing filter that extracts edges in the first image, and generates a second edge image by applying an image processing filter that extracts edges in the second image. The control device then finds common edges where a first edge extracted in the first edge image and a second edge extracted in the second edge match each other, removes the common edges from the second edge image, and outputs a second image from which the common edges are removed.

  • Publication number: 20160132724
    Abstract: An image processing device combines an image of a medium exposed to visible light and an image of the medium exposed to ultraviolet light so that parts printed with UV ink can be easily identified. A control device (image processing device) has an image acquisition unit that drives an image sensor -and acquires a first image by imaging the face a check when exposed to a visible first light, and acquires a second image by imaging the face of the check when exposed to an ultraviolet second light; a reverse image generating unit that generates a reversed second image by reversing light and dark in the second image; and a second synthesizing unit that generates a second synthesized image by combining the first image and the reversed second image. Because the reversed second image that is the reverse of the second image becomes an image that is light overall, a drop in the luminance and a drop in the contrast of the first synthesized image can be suppressed, and parts printed with UV ink are easily discerned.

    Abstract: A membrane electrode assembly includes a rod-shaped or tubular anode, an anode terminal connected to the anode, a cathode disposed at a position apart from the anode so as to face the anode, and a membrane that separates the anode from the cathode. The cathode includes a line-shaped or strip-shaped cathode-supporting portion and a cathode claw that extends to the left, right, or both left and right from the cathode-supporting portion and that is curved along an outer periphery of the anode. The cathode-supporting portion and the cathode claw form an anode-holding portion of the cathode. The membrane includes a membrane strip, and the membrane strip is disposed on the cathode claw to be in contact with the cathode claw so that the anode is held by the anode-holding portion of the cathode with the membrane strip therebetween.

  • Patent number: 9260093
    Abstract: A brake apparatus includes: a displacement member which is displaced with respect to a disk rotor; a friction member which presses the disk rotor by being pressed by the displacement member thus displaced so as to generate braking force; a hydraulic braking apparatus which displaces the displacement member using hydraulic pressure; an electric-powered braking apparatus which displaces the displacement member using a force that differs from the hydraulic pressure; and a brake ECU which controls the hydraulic braking apparatus based on information acquired from a detection unit which detects information having a correlation with the hydraulic pressure applied to the displacement member. When the electric-powered braking apparatus operates in a state in which braking is being performed by the hydraulic braking apparatus, the brake ECU controls the hydraulic braking apparatus or otherwise the electric-powered braking apparatus so as to suppress hydraulic pressure fluctuation.

  • Patent number: 9238454
    Abstract: In a brake control system, a power supply portion supplies a voltage to a plurality of actuators. When a first actuator is supplied with a voltage equal to or higher than a first minimum operating voltage from the power supply portion, the first actuator operates to perform a first function. When a second actuator is supplied with a voltage equal to or higher than a second minimum operating voltage from the power supply portion, the second actuator performs a second function. The first minimum operating voltage and the second minimum operating voltage are set to be different from each other by a predetermined value so that the first actuator and the second actuator stop operating in a predetermined sequence with a decrease in the supplied voltage.

  • Publication number: 20160010580
    Abstract: An object is to provide a method and an apparatus which can be implemented with a simplified and inexpensive configuration without causing a misfire in a combustion state. In a fuel-Cetane-number estimation method of the present invention, a map which specifies a relationship between the Cetane number and a control parameter at which NOx concentration of exhaust gas reaches a predetermined value is prepared in advance. Then, the control parameter is controlled variably to detect transition of the NOx concentration of the exhaust gas of the internal combustion engine, and thereby the control parameter of the internal combustion engine at which the NOx concentration has reached the predetermined value is obtained, and the Cetane number which corresponds to the obtained control parameter is estimated on the basis of the map.

  • Patent number: 9195474
    Abstract: A print control device, a control method of a print control device, and a recording medium storing a program enable easily configuring a peripheral device connected to a printer. A POS terminal that configures peripheral devices connected to a receipt printer has a device configuration selection unit for selecting a configuration of peripheral devices; and a device configuration screen display unit that displays a configuration screen for the peripheral devices based on the selected device configuration. Because a configuration screen for a peripheral device that is not connected to the receipt printer (a configuration screen that is not needed) is not displayed, the risk of creating confusion regarding the configuration of a peripheral device for the user can be reduced.
