Title: Semiconductor memory device
Inventor: NAKAZATO HIROSHI
IPC: H01L21/8242
Filed: 1988-04-25
Abstract: PURPOSE:To shorten the information propagating time to a readout terminal by detecting the coincidence/noncoincidence between a write address and readout address and directly outputting write information to the readout terminal in accordance with the detected signal. CONSTITUTION:A coincidence/noncoincidence detection circuit 20 inputs write addresses WA1-WA4, readout addresses RA1-RA4, and a write controlling the inverse of WE, detects coincidence/noncoincidence between the write addresses and readout address, and outputs a coincidence signal 40. A switching circuit 30 switches the flow of signals so that the write addresses WA1-WA4 can be outputted directly to readout terminals R1-R4 in accordance with the signal 40. When such constitution is adopted, write information can be outputted to the terminals R1-R4 without consuming time except the time to be spent for passing through the switch of the circuit 30 because the information is not passed through a RAM cell group 10, when the write addresses WA1-WA4 coincide with the readout addresses RA1-RA4.

Title: Creatinine analysis method
Inventor: SAGUSA TOSHIYUKI
IPC: G01N33/70
Filed: 1978-08-23
Abstract: PURPOSE: To eliminate the influence dependent upon bilirubin which exists together, by adding a reducing agent, which does not disturb creation reaction of creatinine picrate but stops oxidation of bilirubin, to a serum sample.  
     CONSTITUTION: Creatinine included in a blood sample is reacted on a picric acid to obtain a creatinine concentration from the reaction speed. At this time, a reducing agent is added which does not disturb creation reaction of creatinine picrate but stops oxidation of bilirubin. An optimum reducing agent is an ascorbic acid. When the ascorbic acid is added, the picric acid is deoxidized to generate picramine. Though the spectrum of bilirubin is deformed slightly just after ascorbic acid addition, it is stabilized after.
