Title: Fet amplifier
Inventor: ONO TOMOHIKO
IPC: H03F1/52
Filed: 1987-07-17
Abstract: PURPOSE:To protect an FET from an excessive input signal without complicating the constitution of an amplifier by adding a gate current detecting circuit to the FET bias circuit of an FET amplifier. CONSTITUTION:When the microwave input signal of an FET unit amplifier is excessive, the gate current of an FET 13 starts to flow, and by the gate current, a voltage drop is generated at a gate current detecting resistance 19. The voltage drop is amplified by a detecting amplifier 20 and converted to a suitable voltage, and thereafter, it is sent to a controller. The controller changes the gate bias potential of the FET 13 and narrows down a drain current. By the action, the amplification factor of the FET 13 is reduced.

Abstract: PURPOSE:To manufacture a roller excellent in durability inexpensively and easily. CONSTITUTION:An elastic roller 4 which is obtained by applying a primer to the surface and drying the same is inserted into a PFA resin tube 5 and a gas holding body 9 is wound round the outer circumference of the PFA resin tube 5 further. Air 10 which is in existence by being included within the gas holding body 9 is expanded by heating the same. Therefore, the PFA resin tube 5 is pressed against the elastic roller 4 from the outside by expansion of the air 10 along with expansion of the PFA resin tube 5 and elastic roller 4, they are stuck to each other and adhesion of a primer is accelerated. Therefore, the PFA resin tube 5 and elastic roller 4 are stuck firmly to each other and a roller superior in durability is obtained. A nonshrinkable PFA resin tube having bad adhesion to the elastic roller 4 may be good as the PFA resin tube 5. The film pressure of nonshrinkable PFA resin tube 5 is uniform and the resin tube per se is inexpensive.
