Patent JP-H1127057-A (JP)
Title: Semiconductor integrated circuit
Inventor: YAMAGUCHI HIROSHI
IPC: H03F1/30
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To always supply a constant current despite the variance of characteristic of a MOS transistor TR serving as a load by preparing a standard current source and a current mirror circuit having the value equal to the current value of the current source and making the current source use a saturation area of the MOS TR. SOLUTION: An nMOS TR 1 applies a constant current V1 to a control terminal 12 to flow an approximately constant current (in ) in a saturation area, applies the self-bias to the gate voltage of a pMOS TR 2 to flow the same current and is also biased by a pMOS TR 3 at the same voltage level. Therefore, the current value (ip ) is supplied when the TR 3 operates in the saturation area. In the same way, a pMOS TR 4 flows an approximately constant current (ip ) in the saturation area by applying the constant voltage V2 to a control terminal 13. Then the TR 4 applies the self-bias to the gate voltage of an nMOS TR 5 and is also biased by an nMOS TR 6 at the same voltage level.

Abstract: PURPOSE:To enable to efficiently inject an insulating agent even into a plurality of bodies to be impregnated having different volumes, in a vacuum dropping apparatus for  injecting the liquid insulating agent, by combining a rotary distributing vessel with a stationary branching vessel divided into several pieces. CONSTITUTION:The interior of a vacuum impregnating cell 10 is evacuated, and then a distributor 12 is rotated at a low speed by driving a driving source 23 while opening a valve 8a. Consequently, a liquid insulating agent 7, being uniformly distributed to each chamber of a branching vessel 14, starts dropping. When the insulating agent 7 is accomulated in the vessel 14, the insulating agent 7 is let flow out through each outflow opening 13 and injected into each body 15 to be impregnated. In this case, the flow rate of the insulating agent 7 passing through each opening 13 is not strictly equal  to the other, and the size of each body 15 to be impregnated is not the same as the other, so that the height of the liquid surface in the body 15 to be impregnated is not equal to the other. In this regard, when the height of the liquid surface in one of the bodies 15 to be impregnated reaches a predetermined value, the driving source 23 is stopped. The insulating agent 7 is collectively injected to some of the bodies 15 to be impregnated in which the height of the liquid surface is insufficient by the operation of a handle 24.
