Title: Urease immobilizing urea electrode and its production
Inventor: TOKINAGA DAIZOU
IPC: G01N27/327
Filed: 1982-10-04
Abstract: PURPOSE:To reduce the time required for measuring with a urea electrode by introducing an amino group into the surface of the structural body for an urease immobilizing film. CONSTITUTION:When a small amt. (for example, 10mul) of a sample such as blood is run with a buffer soln. as a carrier into a capillary 16, the urea incorporated in the sample is hydrolyzed when it contacts with the urease immobilizing film 1 of an enzyme electrode 13, thus producing an ammonium ion. The ammonium ion changes the film potential of an ammonium ion sensitive film 2 and consequently a potential change depending on the concn. of urea in the sample arises between the electrode 13 and a reference electrode 14. The change in the potential is observed as a change of a crest shape in the base line obtd. in the case when only the buffer soln. is flowed with time. The time from the beginning of a change in the crest type until it returns to the base line is regarded as the time required for measuring one sample.

Title: Tracing circuit
Inventor: HAYASHI TAKAO
IPC: G06F11/28
Filed: 1983-09-20
Abstract: PURPOSE:To attain completely the tracing function of a program by using a write control circuit which compares a sample data to be stored with another sample data stored in a preceding step and can prevent the writing when the coincidence is obtained between both data. CONSTITUTION:A sample register 410 reads the storage data of a sample register 12 after receiving a trigger clock signal and delivers the data to a collating circuit after storage. When the same data are obtained continuously from a terminal 11, the circuit 420 detects the coincidence between both storage data of registers 12 and 410 and delivers it to AND circuits 432-434. An AND circuit 431 functions as a gate which transmits continuously the output pulse of a timing circuit 15 as a write command until a write inhibiting signal of a holding circuit 439 is delivered. For a series of actions of a write control circuit 430, a write command fed to a memory 14 is equal to the output pulse signal of the circuit 431. Then the circuit 439 works more than the prescribed number of times to prevent the output pulse signal. Thus no data is written.
