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： This invention is intended to reduce a line rate of a monitoring line necessary for transmission of a picture feature without complicating a system. A video signal xi (n0, n1) of each block is subjected to spread spectrum by multiplying the video signal xi(n0, n1) by a PN sequences SPN1 (n0, n1) (in a step S1). The resultant video signal is orthogonally transformed by DFT, DCT, WHT, or the like (in a step S2). An amplitude component Ai=|Xi(SE0, SE1)| of an arbitrary component (SE0, SE1) in a coefficient Xi(S0, S1) obtained by the steps S1 and S2 is extracted (in a step S3), and the extracted amplitude component is quantized with a step size M (in a step S4). The picture feature F[i] is given as a residue obtained under a modulus Nm of a quantized typical value obtained by the quantization (in the step S4) (in a step S5).

摘要： Feature quantities of a transmitted picture and a received picture are extracted from a first and second block-by-block feature quantity extraction parts which are provided on a transmitting and receiving sides, respectively. The extracted feature quantities are transmitted to a block degradation calculation part which compares the transmitted feature quantities and finds the degree of picture quality degradation for each block. Next, a median filter replaces the degree of picture quality degradation for the each block with a median of the degrees of picture quality degradation among the neighboring blocks of the each block. Then, a degraded block detection part compares the median with a predetermined threshold and detects a degraded block. Finally, a degraded region detection part removes an isolated degraded block and detects a degraded region. According to the invention, local picture quality degradation in a frame caused by transmission failure can be automatically detected with high accuracy.

摘要： In a wireless communication terminal, information from a wireless communication unit is decoded by a communication control unit and analysis information is acquired. A content reception judgment unit instructs the communication control unit to terminate a content receiving process if a mobile radio environment corresponding to transmission rate information of the contents, included in the analysis information, is below a content reception threshold stored in a content reception threshold storage unit. Thus, the wireless communication terminal can judge that the possibility of a failed reception is high before content reception, and needless power consumption can be prevented and power consumption reduced by not performing reception.

摘要： Measurements are obtained by a computing unit based on an output Vh from an indirectly-heated constant-temperature controlling flow rate measuring section (16) and an output Vout from a two-constant-point temperature difference detecting flow rate measuring sections (18a, 18b). In the flow rate measuring section (16), a heating element (163) is feedback-controlled based on a detected temperature by a heat sensing element (162) to obtain an output Vh based on the feedback-controlled condition. An output Vout is obtained from flow rate measuring sections (18a, 18b) based on the detected temperature difference between a heat sensing element (182) disposed on the liquid-flow-direction upstream side of the flow-rate measuring section (16) and a temperature sensing element disposed on the downstream side. A computing unit outputs as a measurement a flow rate obtained based on the output Vh in a flow rate region where a flow rate is larger than a predetermined boundary flow rate, and outputs as a measurement a flow rate obtained based on the output Vout in a flow rate region where it is less than a boundary flow rate. Accordingly, a flow rate is measured with good precision and sensitivity over a wide flow rate range from a trace-amount flow rate region to a comparatively large flow rate region.

摘要： It is sought to provide a coding apparatus which permits high efficiency coding of bi-level images with black-and-white pixels halftoned with error diffusion algorithm. An image input/pixel selection unit selects, from an input image as a bi-level image with black-and-white pixels halftoned with error diffusion algorithm, first selected pixels with respect to a pixel "?" to be coded and second selected pixels as peripheral pixels with respect to the first selected pixels. The first selected pixels are fed to a pixel pattern binary scale translator for translation into a binary number. The second selected pixels, on the other hand, is fed to a pixel value adder for counting of black pixels. The count is fed to a binary scale translator for translation into a binary number. The binary number outputs of the pixel pattern binary scale translator and the binary scale translator are combined to be input to an address input terminal of a ROM having a coding information table.
