Title: Gate bias circuit
Inventor: KANEKO YOSHIAKI
IPC: H03F3/21
Filed: 1986-03-03
Abstract: PURPOSE:To improve the change in output power against the change in input power and input frequency by adding a diode section comprising the series connection of specific numbers to the 2nd resistor section so as to apply a forward voltage when the input power to a FET is large. CONSTITUTION:A bias voltage is divided by resistors 1, 2 to apply the class B operation by applying a voltage at a point A to a gate G of the FET 7, the diode section 8 comprising the series connection of diodes equal to a minimum (n) to satisfy ¦VGSO¦<=n¦VD¦ is added to a resistor 2 so as to impress a forward voltage when the input power to the FET 7 is increased, (n is an integral number, VD is a diffused potentials of diodes and VGSO is a set gate bias voltage). Since no forward voltage is impressed to the diode section 8 when the input power to the FET is small, high impedance is obtained and it is the same as if the section 8 were not connected. When the forward voltage is impressed with the input power increased, the forward diode current flows and the terminal voltage of the diode section 8 reaches n¦VD¦, then the operation point is shifted from the point A (VGSO) into a point B (n¦VD¦) and is not shifted more toward the negative direction.

Abstract: PURPOSE: To prepare the titled compound useful as an antibacterial agent, by reacting an N-substituted-aziridine-2-carboxylic acid amide, etc. with an alcohol or a thioalcohol, and removing the protecting group.  
     CONSTITUTION: The objective compound of formula IV(R 1  is H or lower alkyl; R 2  is lower alkyl, aralkyl, etc.; R 3  is amino acid residue; X is O or S; n is O or 1) is prepared by reacting a compound of formulaI(CO-R 4  is ester or amide; Z is N-protecting group) with a compound of formula II, and removing the protecting group from the resultant compound of formula III. The reaction of the compound of formulaIand the compound of formula II is carried out usually in an organic solvent (e.g. CHCl 3 ) at room temperature or under heating. When the compound of formula II is an alcohol or a thioalcohol, the reaction is carried out in the presence of a Lewis acid (e.g. BF 3 ). The N-protecting group is a conventional amino acid-protecting group, and its removal can be achieved, e.g. in the case of BOC group, by hydrogenating in the presence of a catalytic reduction catalyst.
