Title: Phase lock loop
Inventor: SUZUKI YUTAKA
IPC: H03L7/06
Filed: 1979-08-10
Abstract: PURPOSE:To attain digital phase locking by obtaining phase detection output by deciding the amplitude of a signal component, clock by clock. CONSTITUTION:An amplitude, phase modulated input signal is sent to tuning filter 14 to extract only a continuous carrier component, which is supplied to absolute-value circuit 15, polarity deciding circuit 16 and register 17. Its absolute value is compared to threshold value VTH by amplitude comparator 18, whose output is transferred, clock by clock, to registers 19 and 21 in sequence to obtain data a1 and a2 one and two clocks before aimed time, generating phase detection output PD, providing PD=a0 (1-a-1) a-2<xs>0<c>-1. Then when aimed sampled value c-1 is less than a certain value while amplitude values preceding and following it are greater than the certain value, phase detection is carried out. Phase detection output PD is operated by loop filter part 30 and frequency divider 43 outputs absolute value R of the amplitude of the reproduced carrier.

IPC: G01N30/46
Filed: 1985-05-15
Abstract: PURPOSE:To make it possible to analyze even a very small amount of bile acid in a small amount of a sample with high sensitivity, by separating each bile acid form a sample solution containing various bile acids, e.g. free type, amino acid conjugated type, etc., utilizing the liquid chromatographic method.

The resultant mixture solution is led to the same column packed with immobilized bile acid dehydrogenase, e.g. Pseudomonas testosteroni, and immobilized diaphorase or columns separately packed therewith. The reasurin is reduced in the presence of the diaphorase to form resorufin in the column and light absorption or fluoresence of the resultant resorufin contained in the elute from the above-mentoned column is measured. Thus, the very small amount of the bile acid can be analyzed with high sensitivity.

IPC: G02F1/15
Filed: 1991-03-25
Abstract: PURPOSE:To obtain the process for producing the electrochromic (EC) element which eliminates the treatment to remove the cured resin on substrate surfaces and to avoid damaging the substrate surfaces by constituting the element in such a manner that the sealing resin bleeding to the periphery of the substrates does not infiltrate to the substrate surfaces at the time of sealing. CONSTITUTION:The resin 10 is imposed on either of the EC element on the 1st substrate 1 and the 2nd substrate 9. This 1st substrate 1 and the 2nd substrate 9 are engaged with each other and the two substrates 1, 9 engaging with each other are rotated to discharge the excess resin 10 from the engaging end edge of the 1st substrate 1 and the 2nd substrate 9 and, therefore, the sealing resin 10 bleeding from between substrates is splashed to the periphery by the centrifugal force generated by the rotation of the substrates 1, 9. The adhesion of the resin 10 to the substrate surfaces is thereby obviated and the sticking of the resin 10 in the form of lumps to the substrate end faces is prevented.
