Title: Method for measuring flow speed of vapor in double layered atmosphere
Inventor: ARAI MASAKI
IPC: G01F1/74
Filed: 1982-03-08
Abstract: PURPOSE:To measure the flow speed of the vapor with a small amount of error, by dividing detected temperature data by a time which is longer than the drying time of a waterdrop, obtaining the maximum value of each sector, and averaging the maximum values of this time and the previous times. CONSTITUTION:The temperature data of the vapor from a temperature detector T is sent to an operating circuit 14, and divided into sectors which are longer than the evaporating time of the waterdrop attached to the detector T. The maximum value of each sector is obtained. The average of said maximum value and the maximum values in the several previous sectors is obtained, and an average vapor temperature TAVE in the sectors is obtained. This value gives a specific gravity of the vapor corresponding to a detected pressure signal (p) from a pressure detector 11. Based on this value and a detected value DELTAP from a flow speed detector 10, the flow speed of the vapor is computed in a vapor flow speed operating circuit 13. Since the effects, which are caused by the attachment of the waterdrops to the temperature detector T and the fluctuation of the temperature due to the evaporation, are decreased, the measurement errors are reduced.

Title: Acoustic signal transformation and encoding and decoding method
Inventor: IWAGAMI NAOKI
IPC: G10L19/038
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To enable accurate quantization with a relatively smaller number of code vectors when transformation is performed in frequency domain for vector-quantization. SOLUTION: Frequency domain coefficients of an input acoustic signal are divided into small vectors, and corresponding weight coefficients are also divided similarly, and by using these corresponding ones, optimal code vectors are searched from a code book 39. In this case, the presence or absence of a minute structure is judged in the spectrum of the input acoustic signal, and if the minute structure exists, approximately a third of the absolute values among the element are left in descending order to the code vectors taken out of the code book 39 and are deformed so that the amplitudes become large by defining the other elements as zero, while, if the minute structure does not exist, they are used without performing the deformation.
