IPC: H03H7/24
Filed: 1984-07-13
Abstract: PURPOSE:To decrease the deviation of attenuation depending on a frequency by forming an isosceles triangle by moving center conductors and arranging an attenuation near the apexes so as to decrease the difference of the length of signal path. CONSTITUTION:A 3-stage type step variable attenuator is formed by connecting attenuator units 5-7 in series. Then the attenuator unit 5 (similarly as the units 6, 7) is formed as follows: that is, an isosceles triangle where a movable center conductor 52 for bypass line selection is used as a base and movable center conductors 53a, 53b for selecting an attenuation element are used as isosceles sides is formed and an attenuation element 56 is provided near the apex. Through the forming above, the difference in the length of the signal path at switching is decreased. Thus, the deviation of attenuation depending on the frequency is decreased.

Abstract: PURPOSE: To realize highly accurate operation without increasing the load on a host CPU by providing an operating unit having such pipe line structure as the data can be collected at a sampling period equal to an operating frequency being given and then processed. CONSTITUTION: When a CPU 11 delivers a start command and a reagent is thrown in, output from an object 12 is digitized through an A/D converter 13 and a pipe line operating unit 15 acquires the operating frequency thereof. The data is held by a data holding means 21 over two periods and a subtractor 22 determines the difference between data at the times of (i) and (i-1) thus obtaining the inclination at the time (i) Subsequently, an adder 23 and a shifter 24 average the inclinations at the times (i) and (i-1) to determine the variation rate at the time (i). If the variation rate exceeds a set value, an interruption output is returned from a comparator 25 to the CPU 11 thus notifying the start of reaction.  Consequently, the data can be sampled at more accurate period than a programming method and the number of data to be collected can be increased without increasing the load on the CPU 11.
