Title: Electric automobile
Inventor: TAGURI KENTO
IPC: H02M7/48
Filed: 2016-08-30
Abstract: PROBLEM TO BE SOLVED: To detect the lowering of the static capacitance of a smoothing capacitor, in an electric automobile.SOLUTION: A hybrid vehicle 10 comprises a motor 230, a current sensor 215, first and second power converters 220, 270, a smoothing capacitor 225 and a controller 300. The first power converter 220 converts the output power of a battery 210 to the drive power of the motor 230. In the first power converter 220, an output is changed according to an accelerator operation of a driver. The second power converter 270 is connected to the smoothing capacitor 225 in parallel therewith, and can be operated by a constant output without depending on the accelerator operation of the driver. When a ripple current which is not lower than a set threshold out of ripple currents measured by the current sensor 215 is detected more than the set number of times in a state that the first power converter 220 is stopped and the second power converter 270 is operated by the constant output, the controller 300 determines that the static capacitance of the smoothing capacitor 225 is lowered.SELECTED DRAWING: Figure 1

Title: Control device, image processing method and image processing program
Inventor: HIRANO SACHIKO
IPC: B41J2/525
Filed: 2016-09-07
Abstract: PROBLEM TO BE SOLVED: To improve color reproducibility even in a case where an input image has high saturation or high lightness.SOLUTION: When performing printing in which a white ground is imparted to a color input image, multi-value pixels of the input image and the white ground are generated and it is discriminated whether a color of the multi-level pixel of the input image is a predetermined color. Both a pixel value of each of color material colors of the input image and a pixel value of a white color of the ground are subtracted in such a manner that a total value of both the pixel values becomes equal to or less than a predetermined value. After a color material amount during the printing is limited, the pixels are transformed into a binary pixel array for each color material color using the area gradation method. Based on the binary pixel array that is obtained by transforming the multi-value pixels of the predetermined color, a pixel position at which any one of C, M and Y color components is present and a pixel position at which no color component is present are identified. At least one white pixel disposed at any one pixel position is rearranged at the other pixel position where a white pixel is not disposed, with respect to the white binary pixel array, and a result of the rearrangement is outputted.SELECTED DRAWING: Figure 6

Title: Shift range control device
Inventor: KAMIO SHIGERU
IPC: H02P23/18
Filed: 2016-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a shift range control device which can stably control the drive of a motor related to the changeover of a shift range.SOLUTION: A feedback control part 60 of a shift range control device 40 performs feedback control based on a motor actual angle Cen and a motor speed Msp. A feedback value setting part 63 sets a feedback value so that a phase of the motor speed Msp is progressed on the basis of the motor speed Msp. When a required shift range is switched, a changeover control part 65 performs the feedback control. When a different value e between a target angle Cenand the actual angle Cen reaches an angle determination threshold e_th or less, the feedback control is switched to a fixed-phase energization control, and a motor 10 is stopped. By this constitution, a speed signal having a detection delay is fore-read by a signal which has performed the phase progress. Since the speed signal is fore-read and fed back, hunting is prevented, and the drive of the motor can be properly controlled.SELECTED DRAWING: Figure 4
