Abstract: An improved knockdown chair having opposing substantially C shaped support arms, substantially L shaped tubular seating arrangement, sock type seating portion cover, front reinforcing member, and bottom reinforcing member, wherein each of the opposing substantially C shaped support arms are of laminate construction and have an upper arcuate arm support, front arcuate portion, and substantially straight bottom, the substantially L shaped tubular seating arrangement having a tubular seat back and tubular sitting portion telescopically interconnected one to the other, and wherein each of the opposing substantially C shaped support arms is opposingly removably fastened to the substantially L shaped tubular seating arrangement, the improvement comprising combination with each of the opposing substantially C shaped support arms of a substantially S shaped reinforcing member of laminate construction removably fastened to the upper arcuate arm support and the substantially straight bottom for reinforcing each of the

Abstract: A method of making an armrest that is mountable between adjacent left and right passenger seats includes: separately forming two receptacle parts by molding a prepreg in a first mold assembly, the receptacle parts being adapted to hold personal objects and each having a looped wall surrounding a slot; forming an armrest frame by molding a prepreg in a second mold assembly, the armrest frame including a lower frame portion having a plurality of downwardly extending legs, and an upper frame portion disposed on top of and bridging the legs; and positioning the receptacle parts within the second mold assembly and combining the receptacle parts with the upper frame portion during the forming of the armrest frame in the second mold assembly, thereby providing a one-piece unitary structure having the receptacle parts and the armrest frame.

Abstract: An RF MOS transistor having improved AC output conductance and AC output capacitance includes parallel interdigitated source and drain regions separated by channel regions and overlying gates. Grounded tap regions contacting an underlying well are placed contiguous to source regions and reduce distributed backgate resistance, lower backgate channel modulation, and lower output conductance.

Abstract: An armchair is disclosed. The armchair has a seatback, a pair of armrests securely mounted on both sides of the seatback, a spring-like base securely and respectively engaged with the pair of armrests and a seat a side of which engages with a bottom side of the seatback and provided between the armrests. A pneumatic cylinder is provided between the seat and a joint of the seatback and one of the armrests, such that the inclination difficulty of the seatback with respect to the seat is adjusted via the adjustment of the pneumatic cylinder.

Abstract: A chair is provided with a frame defining a curved arm support, a seat supported in the frame, and a back. An arm member is movably mounted on the arm support and operatively connected to the back so that movement of the back between upright and reclined positions is controlled by the arm member and arm support. A resilient spring is operatively connected to the back to bias the back towards an upright position. In one embodiment, the resilient spring encompasses the curved arm support and provides support for a seated user's arm. In another embodiment, an arm cap covers the resilient spring. Optionally, the arm cap slideably rides on roller bearings over the curved arm support. In another embodiment, the curved arm support and arm member are telescopingly arranged, and the resilient spring is operably placed therein. Another embodiment includes first and second springs, the second springs being disengageable to produce discrete selectable levels of bias force for biasing the back toward the upright position.

Abstract: A spring-action chair comprising a seat frame having left and right sides and left and right spring-action support means rigidly secured to the left and right sides of the seat frame for elevating the seat frame above the ground. Each support means comprises an elongated, continuous support member of composite configuration having sections which include a first section extending upwardly and rearwardly from a first ground engaging end along a first angle, the member then having a first reversed bend in an elevated horizontal intermediate section extending forwardly therefrom, adjacent the seat frame to a second reversed bend, with the member then having a second angular section extending downwardly and rearwardly at a second angle and terminating at a second ground engaging end.

Abstract: A chair particularly suited for institutional multipurpose rooms, and the like, includes a base and a shell with a back and a seat which are constructed for generally contemporaneous movement. A first support connects the base with a medial portion of the seat to support the same in a cantilevered fashion, and is resiliently flexible to permit the shell to rock in response to fore-to-aft movement of a seated user. A second support connects the base with the back, and is also resiliently flexible to permit and control the rocking motion of the shell in a manner that provides improved comfort, and reduces sitting fatigue. Preferably, the support also permits the shell to move in a controlled manner from side to side in response to lateral movement of a seated user.

Abstract: An occasional chair is provided with two Z-shaped sides, two cross-members, and a seat comprising a rim and a mesh. The mesh allows for ventilation and the Z-shaped sides make the chair flexible. A plurality of these chairs can be stacked for easy storage.
