摘要： A device for detecting leakage of liquid in a tank, in which, even if the liquid in the tank is a low viscosity liquid, degradation in flow rate measurement accuracy by an indirectly heated flow rate meter can be suppressed, so that a very fine amount of leakage can be accurately detected for a long period without degradation in detection accuracy. The liquid in the tank that is led in and out from a liquid lead-in/lead-out section (12) is lead in and out from the lower end of a measurement fine tube (13b, 13b′, 13″) positioned in the flow rate measurement section (13). A measurement tube (17) of a liquid storage section (14) is connected to the upper end of the measurement fine tube. The measurement tube (17) has a larger cross-sectional area than the measurement fine tube. The device has a flow rate sensor section that is attached to the measurement fine tube and measures the flow rate of the liquid. The flow rate sensor section includes a heater (135) and temperature sensors (133, 134). The distance L1 in the measurement fine tube measured from a position corresponding to the heater (135) to an upper end opening of the measurement fine tube is not less than 20 mm and not more than 45 mm.

摘要： A plurality of cameras is placed so that those optical axes become parallel to the Z-axis and are in relative position t on the XY plane. Multi-view video compression coding apparatus determines depth distance Z and unit normal vector (nx, ny, nz) of the arbitrary point in the surface of the object, moves the first block by disparity vector based on t and Z, transforming the first block by linear transformation matrix based on t, Z and n, then, matching the first block to block of the second picture. Then, while changing Z and n arbitrarily, the second block of the second picture which is most similar to the first block is searched for. And the apparatus derives a prediction error between the first block and the second block, codes the prediction error, and adds Z and n to coded data.

摘要： Picture having a band of 6 MHz is distributed to the set-top box (STB) 14 via the compression encoder 11, the distribution server 12, and the network 13. The low-pass filter 151 in the picture quality monitoring apparatus 15 removes high-frequency components of an inputted digital signal and inputs luminance signal, the band of which is limited to 4 MHz, into the PSNR calculator 153. The Y/C separator 152 separates a luminance signal from NTSC analog composite signal, which are sent out from the set-top box 14. The separated luminance signal has a band of 4 MHz. The PSNR calculator 153 calculates PSNR between the luminance signal from the low-pass filter 151 and the luminance signal from the Y/C separator 152.
