Abstract: PURPOSE:To prevent degradation in linearity due to a resistance error by extracting an output of a resistance circuit network DA converter with an output of a PWM conversion circuit through switching and smoothing and outputting the result. CONSTITUTION:A bit detection circuit 1 detecting a prescribed number of bits from the position of the LSB of an input data, a shift circuit 2 shifting an input data in response to an output of the bit detection circuit 1, a resistance circuit network DA converter 4 converting an output of the shift circuit 2 into an analog value and a PWN conversion circuit converting an output of the bit detection circuit l into a pulse width are provided and an output of a resistance circuit network D/A converter 4 is switched and extracted by an output of the PWM conversion circuit 3 and smoothed and outputted. In this case, the bits of input data are shifted every time each bit is 0 from the position of the LSB of the input data by a prescribed number of bits and the result is inputted to the resistance circuit network D/A converter 4, then the resistor corresponding to the high-order bits of the resistance circuit network B/A converter 4 is used repetitively every time data reaches a half. Thus, the degradation in the linearity due to resistance error is prevented.

Title: Measuring method for length of buried metal rod fixed by mortar
Inventor: MIURA SATORU
IPC: G01B7/02
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a non-destructive measuring method for the length of a metal rod which is fixed inside a base by mortar. SOLUTION: A pulse voltage is applied to an end of the base surface side of a buried metal rod 3 which is fixed by mortar 2 in a base 1 at a ground potential. The time (t) (μS) which elapses until reflected waves of the pulse voltage at the other end of the metal rod 3 reach the end from its application is measured by an oscilloscope or the like. Traveling speed (v) of the pulse voltage is computed by v=330/(μs εs )<1/2> (m/μS) on the basis of the relative permeability μs and the relative permittivity εs of mortar, and the length L of the metal rod 3 is found by L=(vt)/2(m). The traveling speed (v) of the pulse voltage may be found by v=2L0 /t by using the measured value of the time (t) which elapses until the reflected waves reach the end from the application of the pulse voltage.

Abstract: PURPOSE:To smooth the connection of the supercharger pressure control and prevent the fluctuation of the supercharge pressure at the time of switching by operating respective actuators of an exhaust leaking means and a waist gate valve with the same operating characteristic in outline to the installation operating pressure. CONSTITUTION:When an engine 101 reaches the high flow quantity area, a control unit 146 flows a part of the exhaust gas with an exhaust leaking valve 130 to give the prerotation before opening an exhaust cut valve 123 to operate the second turbosupercharger of the high flow quantity side, and opens the exhaust cut valve 123 at the time that the rotation is raised.

Abstract: PURPOSE:To correct the measurement error of a three-dimensional measuring instrument with high accuracy by storing measurement errors and the inclined angle of a measuring plane out of the measured data of a reference spherical surface and correcting the error of the measured value of an arbitrary plane. CONSTITUTION:In order to prepare correction data, a circular arc in the (x) direction passing through an origin which is set at the front end of a reference spherical surface 1 is measured by x-z measurement and relations between the inclination of a plane at measurement points and errors produced in the calculating equation of the reference spherical surface are stored in a computer by eliminating a fluctuating component from an (x, z) point string which are measurement data. The y-z measurement is also made similarly. At the time of performing actual measurement, a probe error is corrected by eliminating the fluctuating component from the measuring point string which is measured data, calculating the inclination of the plane at each measuring point, and subtracting the error amount corresponding to the inclination found by the measurement of the reference spherical surface.

Abstract: PURPOSE: To provide a drawing editing device and graphic editing method which can easily and securely specify an object to be edited when editing is performed in the order not in number order like sequential editing for every group. CONSTITUTION: The following is the explanation with an example of alteration of a character shape. When 'hen' (left-hand radical of Chinese character) is selected in an edited object specifying method selection menu, a list of 'hen' kinds is displayed (S1-S4). When, for example, 'sanzui' (one of left-hand radicals) is selected here (S5), its character list is displayed (S6). At this time, characters which are already edited are reversed and displayed and a starting character which is not edited is encircled with a thick frame indicating temporary specification (S7). To specify the temporarily specified character, 'OK' is instructed with a pointing device and the specification of the edited object ends (S8 and S9). When another character is specified, the thick frame moves to the character, so that is confirmed and 'OK' is instructed.
