Abstract: A piping joint for preventing pipe members laid across the connection end faces of two adjacent structural elements from being damaged by changes in the relative positional relationship between the two adjacent structural elements due to the expansion and contraction caused by changes in the temperature or external stresses. The piping joint connects the end portions of the two pipe members laid in two structural elements whose connection end faces can displace relatively to each other, between the connection end faces to make the two pipe members communicate. It comprises a fixed unit (30) fixedly embedded into the connection end face of one of the structural elements and a movable unit (50) supported by the fixed unit so as to be movable along the connection end face. The pipe member in the structural element is connected to the fixed unit, and the pipe member in the other structural element is connected to the movable element. The two pipe members communicate in the fixed unit.

Abstract: In an lens holder, a lens 10 inserted in an insertion hole 2 is bonded and secured to a lens holder 1 by an adhesive agent poured in slots 4 formed in such a manner as to divide an outer wall portion 3. Since a sufficient amount of adhesive agent can be allowed to adhere to the lens, the lens can be fixed to the lens holder with sufficient strength. In addition, since the adhesive agent 20 poured in the slots 4 overflows also to the outer side of the slots of the lens holder 1, it is possible to reduce the amount of adhesive agent 20 flowing into the insertion hole 2 side, and it is possible to prevent the adhesive agent from adhering to the surface of the lens 20.

Abstract: A production method of a GaN-based compound semiconductor having excellent crystallinity and a GaN-based semiconductor device produced therefrom. A discrete SiN buffer body is formed on a substrate, and a GaN buffer layer is formed thereon at low temperatures and a GaN semiconductor layer is then formed at high temperatures. By forming the discrete SiN buffer body, the crystal growth, which is dependent on the substrate, of the low-temperature buffer layer is inhibited and monocrystallization is promoted to generate seed crystals used at the time of growing the GaN buffer layer. Further, by forming SiO2 discretely between the substrate and the SiN buffer body or by forming InGaN or a superlattice layer on the GaN semiconductor layer, distortion of the GaN semiconductor layer is reduced.

Abstract: A drill bit including a bit body and a plurality of blades formed in the bit body. The blades are formed, at least in part, from a base matrix material that on one embodiment is impregnated with abrasive particles. One side of the bit is formed, with respect to its axis of rotation, to a smaller radius than the opposite side of the bit. The asymmetry of the bit enables the bit to drill a larger diameter hole than a pass through diameter of the bit. The opposite side defines a contact angle between the bit and a formation. In one embodiment, the contact angle is at least 140 degrees. In one embodiment, a plurality of inserts may be located on the blades to provide gage protection. In another embodiment, the bit may also include a gage sleeve that helps keep the bit stabilized in the wellbore.

Abstract: A method for controlling a subsea well that includes shutting at least one blowout preventer, opening at least one isolation line, and circulating an influx out of a well while an inlet pressure of a subsea mudlift pump is adjusted to maintain a substantially constant drill pipe pressure at an initial circulating pressure. After the influx is circulated out of the well, drilling mud with a kill mud weight is pumped into the well. The drill pipe pressure is reduced according to a preselected drill pipe pressure decline schedule until the kill mud weight drilling mud reaches the bottom of the well. The drill pipe pressure is then maintained at a final circulating pressure by adjusting the inlet pressure of the subsea mudlift pump. The kill mud weight drilling mud is then circulated from the well bottom to the surface at the final circulating pressure.

Abstract: A bi-center drill bit includes pilot and reaming blades affixed to a body at azimuthally spaced locations. The blades have PDC cutters attached at selected positions. In one aspect, the pilot blades form a section having length along the bit axis less than about 80 percent of a diameter of the section. In another aspect, selected pilot blades and corresponding reaming blades are formed into single spiral structures. In another aspect, shapes and positions of the blades and inserts are selected so that lateral forces exerted by the reaming and the pilot sections are balanced as a single structure. Lateral forces are preferably balanced to within 10 percent of the total axial force on the bit. In another aspect, the center of mass of the bit is located less than about 2.5 percent of the diameter of the bit from the axis of rotation. In another aspect, jets are disposed in the reaming section oriented so that their axes are within about 30 degrees of normal to the axis of the bit.

Abstract: A raw gas containing a gas component A with low affinity with an adsorbent and a gas component C with high affinity with the adsorbent are sequentially supplied to at least three adsorption columns, while a desorption gas containing a gas component D which differs from the gas components A and C is supplied to each of the adsorption columns other than the one to which the raw gas is being supplied. When the raw gas is supplied to the adsorption columns, the gas component A having lower affinity with the adsorbent exits the adsorption columns earlier than the gas component C having higher affinity. The gas components A and C can thus be separated from each other. When a gas including an enriched gas component A is discharged from the outlet of each adsorption column, the full amount is extracted out of the system. When a gas including an enriched gas component C is discharged from the outlet of each adsorption column, the full amount is extracted out of the system.
