Title: Enzyme immunoassay for erythropoietin
Inventor: MATSUMOTO HIROJI
IPC: G01N33/53
Filed: 1985-02-28
Abstract: PURPOSE:To measure the enzyme immunity of erythropoietin by forming an antibody-erythropoietin-labeling material composite on an antibody-conjugated insoluble base then measuring the quantity of the labeling material conjugated onto the base. CONSTITUTION:The antibody-conjugated insoluble base formed by conjugating the antibody reacting specifically with erythropoietin (EPO) on the insoluble base and a specimen liquid contg. the EPO are brought into reaction to conjugate the EPO onto the antibody-conjugated insoluble base. The same is then brought into reaction with the labeling material labeling the antibody reacting specifically with the EPO with enzyme by which the antibody-EPO-labeling material composite is formed on the antibody-conjugated insoluble base. The quantity of the labeling material conjugated on the base is then measured or the quantity of the liberated labeling material which is not conjugated is measured. The quick enzyme immunomeasurement of the EPO in an ordinary inspection room at a low cost with high sensitivity is thus made possible.

Filed: 1990-02-22
Abstract: PURPOSE:To efficiently detect reflected light even for detection of a color toner by setting the directivity of a light receiving element narrower than the directivity of a light emitting element in the case of the specular reflection type optical sensor. CONSTITUTION:The light emitting element 3 and the light receiving element 4 are juxtaposed in proximity to each other and are disposed to face a photosensitive body 1.

The directivity of the light receiving element 4 is set narrower than the directivity of the light emitting element 3 in this case. As a result, the incidence ratio of randomly reflected light decreases and the ratio of detecting the specular reflected light is improved. The sensor characteristic sufficient as the density sensor for the color toner is obtd. in this way.

Filed: 1990-02-21
Abstract: PURPOSE:To obtain an air supply mechanism, light in weight, handy to carry and safe, for use with an air gun by detachably attaching to a high pressure air tank a primary pressure reducing valve which opens a check valve forcibly at the time of connection via a check valve capable of being opened or closed due to pressure difference. CONSTITUTION:In filling an air tank 1 with air, a fastening nut 19 is unfastened to disconnect a primary pressure reducing valve 7 from a check valve 2. Since a stopper piece 7 is released from pressing action thereon of the end of a joint pipe 18 and immediately pushed up by the air pressure inside the air tank 1, a taper part 5 is air sealed via an O-ring 11 and there is no possibility of a high pressure air being blown off to maintain the safety. When the high pressure air is supplied with the filling opening of a filling cylinder screwed into the check valve 2, the stopper piece 7 is pushed up due to the difference between the high pressure air and the inner air pressure of the air tank 1 to release taper parts 5 and 9. The high air pressure air flows from the clearances around a projection 10 of a reduced-diameter part 4 through the taper parts 5 and 9, the clearances 8 around the stopper piece 7 and a communication hole 13 of a stopper 12 into the air tank 1. The filling pressure can be raised to about 150kg/cm<2>-200kg/cm<2>.

Abstract: PURPOSE: To prevent jitter and make it possible to make a circuit into an IC, by selecting two-phase, namely, 0-phase and π-phase clocks to form a read clock and by synchronizing receiving data with the unit clock in phase.  
     CONSTITUTION: Receiving data 11 of an NRZ code and clock 12 transmitted together with data 11 have a fixed phase difference. Meanwhile, unit clock 13 is applied to clock generator 15 in clock phase switching circuit 14, and there, 0-phase clock 16 and π-phase clock 17 are formed. One of these two-phase clocks is selected by control signal 20 from control circuit 19 and becomes a read clock 21 and is applied to phase comparator 22 and buffer memory 23. Clocks 12 and 21 are monitored by comparator 22; and if phase relationship between data 11 and clock 21 is not proper, clock selection circuit 18 switches clocks to shift the phase by π and makes data read possible. Data read by memory 23 is reread by buffer memory 24, and consequently, output 25 of memory 24 becomes always the same phase as the unit.
