Inventor: EGUCHI IWAO
IPC: H04L27/227
Filed: 1978-10-11
Abstract: PURPOSE:To obtain a delay detection-system phase demodulator circuit which is stable against temperatures. CONSTITUTION:The input from terminal 101 is branched by 1, and one is branched furthermore by 2, and the other is delayed 4 by 1 bit and is branched 3 through voltage control phase shifter circuit 10. One is subjected to phase detection 6, and the other is subjected to phase detection 7 after 90 deg. phase shift 5 to output signals corresponding to phase difference, and these signals are discriminated 8, 9 to demodulate a prescribed digital signal string. Now, if phase phi exists between inputs of branching circuits 2 and 3, signals A and B based on this phase and signals C and D from discrimination circuits 8 and 9 are inputted to detection circuit 11 to generate a positive or negative voltage according to the polarity of phase slippage, and circuit 10 is controlled by this voltage to correct phase shift fluctuation of delay circuit 4. Thus, it is unnecessary that a considerably severe stability against temperatures is required for the delay circuit.

Title: Analysis of specific combination and device thereof
Inventor: YAMAUCHI CHUICHI
IPC: G01N33/74
Filed: 1991-05-29
Abstract: PURPOSE:To obtain the same detection result as when a sample is diluted, and to set desired measurement sensitivity without incurring the largest intensity change in signals in the case of measuring qualitatively or quantitatively an object to be analyzed by enabling a specific material to exist in a measurement system, and decreasing a labelled material quantity of the object to be analyzed. CONSTITUTION:Quantities of a labelled specific combination material (e) and an insolubilized specific combination material (b) or an insolubilized specific combination material (g) are set constant with each other. In this case, as the quantity of the insolubilized specific combination material (b) is increased, the quantity of the combination material (e) to be excluded outside of a measurement system increases. Furthermore, signal intensity derived from a labeling material (d) being read after reaction decreases. Further, by diluting a sample, the signal intensity can be set on the same level as that in the case when a quantity of an object to be analyzed (a) is used while decreasing. Thereby, the same effect in the case when the sample is used while being diluted can be obtained, so that measurement having desired measurement sensitivity becomes possible in the proper signal intensity.

When the least significant bit 'B' of the input is equal to '1', the product Y is equal to '0' together with the bits B01 and B00 equal to '0' and '1' respectively. In case only A of the input is equal to '1', the product Y is equal to '0' with the bits B01 and B00 equal to '1' and '0' respectively. In such a way, a multiplication circuit formed with combination of logical elements can calculate the results of multiplication with the multiplicand inputs X1-X4 with no input of multiplication, i.e., a fixed number. Then it is not required to produce the partial products and to add these products together.
