Filed: 1984-04-26
Abstract: PURPOSE:To increase the speed of operation and to lower power consumption by applying bias voltage to an Si substrate and a well so that source junctions in each transistor TR are reversely biassed in a CMIS transistor device. CONSTITUTION:Sources 14S and 15S in a TRp and a TRn are each separated from an n type Si substrate 11 and a p well 12, the substrate 11 is connected to a +VBB power supply higher than driving voltage VCC for the source 14S for the TRp, and the well 12 is connected to a -VBB power supply lower than the grounding voltage of the source 15S in the TRn.

Title: Biocatalytic preparation process for peptide
Inventor: HANSUUDEIITAA YAKUPUKE
IPC: C07K1/02
Filed: 1994-04-22
Abstract: 2.1 The enzymatic synthesis of peptides takes place advantageously using proteases although the hydrolysis, associated with the formation of the peptide product, of the acyl-enzyme intermediate and further possible proteolytic cleavages represent a problem in many synthetic reactions. The yield of peptide product is limited thereby, and the removal of by-products is impeded. The new biocatalytic peptide preparation is intended to take place with exclusion as far as possible of unwanted proteolytic side reactions. 2.2 The biocatalytic preparation of a peptide takes place advantageously by using a zymogen in place of the protease customarily used. Since zymogens are protease precursors which are still without proteolytic activity, there is substantial suppression of proteolytic side reactions. Amino acid esters or peptide esters and amino acids or peptide fragments with C-terminal derivatisation are preferably coupled together. The reaction can also take place in a frozen aqueous medium. Particularly suitable zymogens are chymotrypsinogen, trypsinogen, pepsinogen, prorennin or procarboxypeptidase. 2.3 Enzymatic or biocatalysed peptide synthesis.

Title: Protection circuit for switched-mode power supply circuit
Inventor: UCHIDA TOMOAKI
IPC: H02H3/12
Filed: 1978-07-12
Abstract: PURPOSE: To prevent a switching element from being broken down by an overcurrent, by changing the duty factor of switching pulses.  
     CONSTITUTION: A resistor 14 is provided to detect a voltage corresponding to the current flowing through the switching element 13. A monostable multivibrator MM is shifted from a stable state to an unstable on when said current has exceeded a prescribed level. The duty factor of the switching pulses P5 to be supplied to the switching element 13 is changed on the basis of a voltage, which varies with time and which is produced by the time constant circuit CR of the monostable multivibrator when it is shifted to the unstable state. The switching element is thus protected from the overcurrent due to the short circuit of a load or the like.
