Title: Identification signal detection circuit in secam system
Inventor: SUGIMOTO TAKASHI
IPC: H04N11/18
Filed: 1978-09-13
Abstract: PURPOSE: To form the identification signal detection circuit with the differential amplifier circuit which can decide whether a correct isolating action is given beteen the both R-Y and B-Y signals in the SECAM-system color TV and is suited for integration.  
     CONSTITUTION: For the chroma signals of the SECAM system, the R-Y signal is transmitted in a certain horizontal scanning period (SCA) and then the B-Y signal is transmitted via horizontal synchronous signal SY with application of the FM-modulated identification signals I 1  and I 2  at the head part of each of the both signals. Signals SW1(d) and SW2(e) are supplied to the bases of transistors 11 and 12 forming the differential amplifier circuit in order to give the isolation control to signals R-Y and B-Y. And the identification signal detected through FM detection circuit 13 is supplied to the common emitter. Thus the average current of the collector of transistor constituting the current Miller varies to zero (f), plus (g) and minus (j) according to the cases in that the identification signal does not exist and that SW1 and SW2 are accurate or inaccurate respectively.

Abstract: PURPOSE:To allow easy detection with a high sensitivity by forming the analysis piece consisting of a filter medium of a porous film which absorbs, holds or immobilizes a reagent for inspecting a specimen and a water4 absorptive film which is brought into tight contact with this filter medium. CONSTITUTION:The filter medium 1 of the porous film refers to a membrane filter of about 0.1 to 10 mum pore size, ultrafilter of about 10 to 1000Angstrom  pore size, etc., and is formed in a network structure by using nitrocellulose, nylon, etc., for its base material. The analysis piece is obtd. by superposing the filter medium 1 which previously absorbs, holds or immobilizes the reagent for inspecting the specimen and the water absorptive film 2 which absorbs the moisture in the specimen, heating the laminate to about 70 to 80 deg.C to tightly adhere and integrate the medium and the sheet, and cutting the laminate to a required size. The spotted specimen first reacts with the reagent for inspecting the specimen on the filter medium 1 and the product remains on the filter medium 1. The excess moisture is then expelled onto the lower sheet 2 and, therefore, the moisture is practically condensed. Consequently, high-sensitivity detection is relatively easily executed.

Title: Gelation reaction measuring instrument
Inventor: MURAMATSU HIROSHI
IPC: G01N21/83
Filed: 1988-05-10
Abstract: PURPOSE:To exactly measure a gelation reaction and gelation time with a slight amt. of sample by measuring a change in the oscillation frequency of a crystal resonator arising from the gelation of the sample. CONSTITUTION:The crystal resonator 1 is so fixed to a cell 2 that the crystal resonator 1 constitutes the base of the cell. The sample is put into an aq. soln. in the cell and the crystal resonator 1 is oscillated by an oscillation circuit 3. The oscillation of the resonator 1 is influenced by contact of a material with the surface thereof and said influence is reflected as a change in the oscillation frequency. This frequency is measured by a frequency counter 4. The oscillation frequency of the resonator changes largely at the point of the time when the sample is put into the aq. soln. The oscillation frequency changes even during the course of the gelation and since the specified oscillation frequency is attained at the point of the time when the gelation is completed, the gelation time is determined by automatically calculating the time lag from the point of the time when the sample is put into the aq. soln. before the completion of the gelation by a computer 5.
