Title: Constant current source
Inventor: IWASAKI MANABU
IPC: G05F1/56
Filed: 1984-07-19
Abstract: PURPOSE:To obtain an inexpensive constant current circuit extracting an output current proportional to a set voltage by inserting a diode whose forward voltage drop is equal to a base-emitter voltage of a transistor (TR) between a base of the TR and an earth. CONSTITUTION:An output voltage Vout of an operational amplifier 4 is proportional to an input set voltage Vin and the input voltage Vout of a TR11 and an input current IE are not accurately proportional because the current amplification factor hBE characteristic gives the effect. Thus, two diodes 13 are connected in series with a base of the TR11 having the large hBE and the diodes are earthed and the base is given with a negative potential by a resitor 12 connected to a negative power supply -VCC, then it is the same as the case with neglecting a base-emitter voltage VBE apparently because of the forward voltage drop VD of a diode 13. Thus, the voltage Vin versus output current IC have a linearity and an output current proportional to the input setting voltage is obtained.

IPC: F16K31/122
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a structure of pilot Y-type globe valve that reduces pressure loss.
