A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface. Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate. The distribution apparatus can be used in the reaction vessel without the swirl chamber and rough distribution system, e.g., at the top of a vessel.

A quench zone mixing apparatus is supported within a vessel of a reactor by a support structure that includes a concentric hub, which may be formed to act as a torsion tube, and at least a first set of radial beams extending radially outward from the hub and terminating at a support ring that is attached to the reactor vessel wall. In particular, the radial beams comprise a flange that supports the redistribution tray and a web of the beams preferably includes a plurality of openings to allow the passage of fluids across the vessel. In addition, the webs also carry the channels. The radial beams also support the mixing chamber and, in the area between the wall of the mixing chamber and the vessel wall, the radial beams may have a vertical height that slopes downward from the vessel wall to the mixing chamber wall.

The invention relates to a novel structural high-pressure balance valve, which comprises a valve body (1), a stuffing box assembly, a valve rod assembly, a support assembly, a hand wheel assembly, a four-element ring (10) and a split jacket (26), wherein a concave groove is arranged on the inner wall of a top hole of the valve body, the four-element ring (10) is arranged on the concave groove, aninner ring of the four-element ring (10) protrudes out of the concave groove, and the bottom of a projection part is in contact with the top surface of the stuffing box assembly; the valve rod assembly comprises a valve rod (9) inserted into the stuffing box assembly and a valve clack (2), the top of the valve rod (9) is connected with the support assembly through the split jacket (26), the valveclack (2) is a cylindrical cavity, a pressing plate is arranged in the valve clack (2), an inner wall of the valve clack (2) at the upper part of the pressing plate is a screw thread, the screw thread is connected with a thread spacer sleeve (31), the bottom of the valve rod (9) is inserted into the thread spacer sleeve (31), the bottom of the valve rod (9) protrudes, the bottom of the thread spacer sleeve (31) is concave, the valve rod (9) and the thread spacer sleeve (31) are matched, so that the valve rod (9) and the thread spacer sleeve (31) are in lapped joint; the stuffing box assembly comprises a stuffing box (7), a first O-shaped sealing part, a second O-shaped sealing part and a third O-shaped sealing part; an O-shaped ring is an F4 type all-coated fluororubber O-shaped sealing ring, and is an axially assembled structure; and fluid balance holes are arranged on the pressing plate in the valve clack (2) and the thread spacer sleeve (31). The novel structural high-pressure balance valve, provided by the invention, has the advantages of simple structure, convenience for use and small volume.

A band clip includes a body, a band integral with the body, and a clip that is attached to the body. The body has a vertical plate with a band insertion hole and a horizontal plate with a clip attachment hole. The band extends from the vertical plate. Locking holes penetrate the band at intervals. The clip includes a shaft that is fit into the clip attachment hole of the body, a wing on one end of the shaft, a band locking claw at another end of the shaft, and a body locking claw on an intermediate portion of the shaft. The band is wrapped around a group of wires and inserted into the band insertion hole. The band locking claw of the clip is inserted into and locked to a band locking hole, and the body locking claw contacts the surface of the body.

A stacked type semiconductor device has a reduced overall height and reliability of improving the mechanical strength of the stacked structure. The semiconductor device also has improved heat dissipation characteristics. The first interposer has a surface on which the first electrode pads are formed, and the first semiconductor element is mounted such that the circuit forming surface is opposed to the first interposer. The second semiconductor element has a circuit forming surface and a back surface opposite to the circuit forming surface. The second interposer has a surface on which second electrode pads are formed, and the second semiconductor element is mounted such that the circuit forming surface is opposed to the second interposer. External connection terminals are provided on the surface of the second interposer opposite to the surface on which the second semiconductor element is mounted. The first and second inserts are electrically connected to each other by the conductive member therebetween. The back surface of the first semiconductor element and the back surface of the second semiconductor element are fixed to each other by an adhesive.
