摘要:
A biodevice is in an elongated form and has a conductive layer and an insulating layer stacked on a side surface of a shaft member at the center. A cylindrical hollow section is formed through the device, being connected to the exterior at a front end and extending from this front end axially. An electrode section is formed on an inner surface. A sensing substance such as enzyme may be placed at the electrode section to detect a current value corresponding to the concentration or quantity of an object under test placed between a counter electrode and the biodevice.

Included in the digital filtering equipment for extracting a feature quantity from a speech signal in order to execute a speech recognition based on an inputted speech signal are: a) an waveform determining section for obtaining an inputted speech signal and quantizing the speech signal waveform; b) a division value operating section for summing a quantized signal data in a prescribed adjoining region to divide the summation value by the number of summed data, with respect to a data quantized at each point by the waveform determining section, whereby a division value is obtained with the data being centered; c) a comparison section for comparing a division value calculated by the division value operating section and the quantized data calculated in the division value operating section to output logical truth of a comparison result, with respect to each data; and d) a conversion section for converting the quantized data into the selected data points based on an output from the comparison section. Thus, the feature quantity can be extracted only by applying an integer summation and comparison operation, so that performance of arithmetic operation is extremely simplified to be fast and inexpensive.

A blood-vessel-shape measuring apparatus that can accurately measures a shape of a section of a blood vessel is provided. A blood-vessel-shape calculating means 62 calculates, based on respective echo signals detected by first and second arrays 26, 28 that are placed on a skin 20 of a brachial portion 14 as a portion of a living being such that each of the first and second arrays 26, 28 is across a brachial artery 18 located under the skin 20, respective positions of respective portions of the arterial wall that are located right below the first and second arrays 26, 28 and correspond to supersonic-wave elements 26 n of the first array 26 and supersonic-wave elements 28 n of the second array 28, and calculates, based on the respective positions of the respective portions of the arterial wall that correspond to the supersonic-wave elements 26 n , 28 n , a shape of the brachial artery 18 on an orthogonal section thereof. Thus, even if the brachial artery 18 may run, under the skin 20, in a direction that is not orthogonal to the first or second array 26, 28 or is not parallel to the skin 20, an accurate sectional shape of the brachial artery 18 can be obtained.
摘要:
A transmission unit (20) emits an electromagnetic wave having the same frequency f as an output signal from a sending unit (12) in a direction of a measurement axis (x-axis). A detecting unit (30) performs synchronous detection on a reflected wave (R) detected by a directional coupler (32) by an in-phase signal and a quadrature signal of the transmission signal, and by extracting DC component from the detection signal, detects the in-phase component (I(f)) and quadrature component (Q(f))of the reflected wave (R). An analysis signal generating unit (42) mixes the in-phase component (I(f)) and quadrature component (Q(f)) of the reflected wave (R) and signals (I 0 (f), Q 0 (f)), having periodicity corresponding to a prescribed distance (do), and using only one of the resulting side bands, generates an analysis signal (p(f)). Fourier transform unit (44) finds distance to the object of measurement from a profile (P(x)) obtained by Fourier transform of the analysis signal (p(f)).
摘要:
A mucosal vaccine producing an antigen-specific mucosal IgA and a blood IgG in the levels capable of exerting an effective immune induction and an infection-preventing effect, which comprises: (a) an AD vehicle consisting of a synthetic peptide and a lipid(s), wherein the synthetic peptide consisting of the amino acid sequence KnLm (wherein n is 4 to 8 and m is 11 to 20); (b) a carboxyvinyl polymer; and, (c) an antigenic protein, in an amount incapable of producing a sufficient mucosal IgA and blood IgG for exerting an effective immune induction and an infection-preventing effect when used by itself. The mucosal vaccine of the invention has an antibody producing ability which is more potent than those of mucosal vaccines of the prior art, and as a result it can exert an excellent effect even with an extremely small amount of an antigen.
