Title: Variant-type staphylococcus aureus v8 protease
Inventor: YABUTA MASAYUKI
IPC: C07K14/58
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain the subject new protease having an enzymatic activity even under an environmental condition bringing the denaturation of a protein, requiring only the small amount of enzyme since it can perform the scission of the protein even in the presence of a high concentration of urea, reducing the reaction time and giving a hitherto unavailable peptide fragment. SOLUTION: This variant-type staphylococcus aureus V8 protease maintains the enzymatic activity even under an environmental condition bringing the denaturation of the protein. There are several merits such that, even in the presence of a high concentration of urea, the inactivation of the enzymatic activity is suppressed, the required amount of the enzyme added to the reaction system in the presence of urea is small, the reaction time is reduced and further the hitherto not obtained peptide fragment is obtained since the scission of the protein can be performed in the presence of a high concentration of urea.  This enzyme is obtained by separating a chromosomal DNA from the staphylococcus aureus by a usual method, preparing a wild type gene deficient in the part of C-terminal of the natural type V8 protease, obtaining a variant-type gene by designing a primer and performing a PCR, and then expressing the gene.

Title: Power supply control device of terminal equipment
Inventor: SUZUKA KAZUO
IPC: G06F1/00
Filed: 1979-12-13
Abstract: PURPOSE: To reduce greatly the amount of consumption of a power source for a terminal equipment, by making the power supply of the terminal device only when  the signal is produced between the MODEM and the terminal equipment.  
     CONSTITUTION: The input and output are applied to the signal detector 9 provided at the MODEM1 against the terminal equipment 2 of the modulator/demodulator  part 8, and the detection output is produced by the carrier wave detection signal  supplied from the part 8. This state is kept while the transmission request signal is  transmitted from the equipment 2. This detection output drives the relay 15 and  then turns on the relay contact 13. As a result, the power supply is made for the  equipment 2 regardless of the off state of the switch 10 as long as the switch 12 of  the equipment 2 is kept on. Thus the equipment 2 is kept active while the data  signal is transmitted and received. The detection output of the detector 9 is extinguished with the end of transmission/reception, and then the relay 15 is released  to cut off the power supply of the equipment 2.
