Abstract: PURPOSE:To automate a calibration operation for the purpose of compensation and to improve the accuracy of the compensation by using an impulsive gas to compensate the characteristic of a gas meter so that the gas meter of low- speed response is converted to the gas meter having the stabler and higher response. CONSTITUTION:A digital signal processor 10 generates a change in the concn. of the impulsive gas by momentarily opening and closing 3-way solenoid valves 5, 6 when the processor 10 is operated in the mode with which the characteristic of the gas meter is obtd. The valves 3, 4 are controlled as to supply the specified volume of the gas so that the gas concn. is not changed by a pressure change in gas pipes 1, 2 for calibration at this time. The volume of the gas to be supplied is the volume to eliminate the influence of the dead space in the valve 6. The valves 5, 6 are provided in order to change over the gas pipes 1, 2 and make the respectively reciprocal actions. The exertion of the pressure to the valves 3, 4 and the consequent change in the volume of the gas are thereby prevented.

Abstract: PROBLEM TO BE SOLVED: To simplify a circuit configuration and an arithmetic time or the like relating to detection of a motion vector. SOLUTION: A maximum value and a minimum value of a pixel value in a reference block relating to detection of a motion vector are detected (step S2), the pixel value in the reference block and within a retrieval range under a calculated threshold value on the basis of them is coded (1-bit ADRC) to obtain a code value (step S3). A matching arithmetic operation is made on the basis of the code value relating to the pixel value in the reference block and a candidate block and a 1st motion vector is calculated on the basis of the arithmetic result (steps S4-S7).  Then block matching on the basis of a difference between pixel values is conducted as to a new retrieval range obtained by shifting the candidate block relating to the 1st motion vector after conducting motion compensation (step S8) in response to the 1st motion vector in the unit of one pixel to calculate a 2nd motion vector (step S9). A final motion vector is calculated as a sum of the 1st motion vector and the 2nd motion vector.

Title: Multiaxial displacement gage for hemispherical hole bottom
Inventor: KOSUGI MASAYUKI
IPC: G01L5/00
Filed: 1988-03-30
Abstract: PURPOSE:To obtain multiaxial information regarding the rock pressure and deformation state in a base rock at the same time by incorporating a differential displacement gage which detects the quantity of displacement of each core rod when the bottom surface of a hemispherical hole is pressed by each metallic presser. CONSTITUTION:When operating pressure is applied to a cylinder 7 through a pressure line 14, the wall surface in a hole well is pressed by an arm 11 to fix a device main body. When an annular body 10 to which a disk body 12 is fitted moves forth, on the other hand, all core rods 4 are pushed out forward against a spring through the disk body 12 and a spring 13 and all metallic pressers 5 are therefore pressed against the spherical bottom surface of the hole well. Even if the respective metallic pressers 5 and core rods 4 are displaced differently according to the characteristics of the hole well internal wall surface, the core levers 4 are pushed out through the spring 13, so there is no problem. The differential displacement gage 6 measures the displacement, so its signal is led out through a signal line 15. Consequently, the multiaxial displacement of the bottom surface of the hemispherical hole of the well hole is measured at the same time and obtained information is multiplied.
