IPC: H04B1/26
Filed: 1989-12-12
Abstract: PURPOSE:To prevent image interference through simple configuration by providing a frequency converter to convert a frequency-modulated received signal into an intermediate frequency signal and a frequency divider to frequency-divide the intermediate frequency signal, and detecting its frequency-divided output. CONSTITUTION:A signal having passed through a first intermediate frequency filter 11 is frequency-divided by a prescaler 16. Then, the frequency-divided output is inputted to a detection circuit after its higher harmonic is removed by a second intermediate frequency filter 15. In the case the prescaler 16 is interposed, the amplitude of the output signal of the first intermediate frequency filter 11 is limited to be constant in conformity to the limiter characteristic of the prescaler 16. Accordingly, by detecting the output of the prescaler 16 after passing it through the second intermediate frequency filter 15, the frequency deviation of the received signal, that is, modulation information can be obtained. Accordingly, image frequency can be made out of a receiving band, and the removal of an image signal by a high frequency filter 2 becomes easy.

Title: Differential pressure/pressure transmitter
Inventor: KUWAYAMA HIDEKI
IPC: G01L13/00
Filed: 1994-12-26
Abstract: PURPOSE: To enable the preventing of the destruction of a sensor by providing a pressure receiving chamber with a deformation member for changing the volume of the inside of the pressure receiving chamber by a differential power or a pressure to suppress a rise in pressure within the pressure receiving chamber. CONSTITUTION: A spherical recess part 36 is formed at the central part of a recess part 35 communicating with a pressure introduction port 32 and a ball body 37 is housed therein functioning as deformation member that is made of a material at a large volumetric compression rate such as teflon or rubber and is deformable by a pressure exceeding a specified value. A measured pressure applied into a lead pipe is transmitted to the recess part 35 through the introduction port 32 and applied to a sensor 21 through a liquid sealed into a diaphragm 25. At this point, even when the ball body 37 is deformed, the supply of the pressure from the lead pipe prevents measuring errors. On the other hand, when a temperature rise occurs in a closed space with the closing of a valve in the course of the lead pipe, a fluid inside expands to raise the pressure.  But the volume of the ball body 37 reduces and suppresses a pressure rise within the pressure receiving chamber by absorbing the volume increased thereby allowing the preventing of an excessive pressure from being applied to the sensor 21.

IPC: B23Q17/20
Filed: 1993-12-21
Abstract: PURPOSE:To accurately extract a feature point of a work by calculating a calculation range by using point-row data indicated by a matrix and a characteristic matrix statistically processed. CONSTITUTION:When a cross sectional shape of a work 10 is measured by means of a cross sectional shape measuring sensor 11, a matrix-conversion operating section 15 converts the obtained point-row data of the cross section into matrix formation data. In a learning stage, a characteristic matrix-forming section 18 converts a calculation range inputted by each point-row data into matrix formation data to form a characteristic matrix. A statistics operating section 20 averages the characteristic matrices formed up to that time. The characteristic matrix is learned step by step in the experience as an intermediate item combining in the probability the point-row data with the calculation range. In an execution stage, a sample range calculating section 22 calculates a calculation sample rang based on the point-row data represented by the matrix and averaged characteristic matrix and a virtual point-calculating section 23 applies a prescribed calculation operation to the inputted calculation sample range, thereby obtaining the virtual point (feature point).
