摘要:
A three-dimension adjustable hidden furniture door hinge is designed to include a travel member that can be fixed onto the door, an adjustable member that can be fixed onto the door frame and an arm segment connects these two members, the adjustable member includes three tiers of boards, a base board in the lower tier can be fixed onto a door frame, a middle board in the middle tier that can slide up and down on top of the base board, and an adjustable board in the upper tier on top of the middle board that can slide back and forth; there are matching grooves and directional tabs formed on the boards; three cam screws are used to provide up-down, back-forth, and left-right position adjustment, there is no need to loosen up other screws, the entire adjustment process is simple, quickly and energy saving.
摘要:
An on-chip circuit for protection against electrostatic discharge (ESD) is disclosed. Unlike conventional ESD protection circuit using high turn-on voltage diode string, the circuit uses a plural of enhancement-mode HEMT/MESFET triggered by a shorter diode string to shunt large ESD current for protected susceptive RF circuit. Further, by using dual-gate technology of enhancement-mode HEMT/MESFET, the on-chip ESD protection circuit has the less parasitic capacitance without expanding device size for vulnerable RF circuit.
