Abstract: A turbocharger includes a compressor housing, a bearing housing and a back plate. A discharge scroll chamber has such a shape that a cross-sectional area thereof gradually increases toward a discharge port in a circumferential direction. The compressor housing includes a scroll piece assembled to a shroud piece. The scroll piece includes a suction port-forming portion, a suction-side concave surface and a scroll outer periphery. The shroud piece includes a shroud fit-in portion, an inner peripheral concave surface, a shroud surface and a diffuser surface. The back plate includes a facing surface, an outer peripheral annular fit-in portion and an outer peripheral concave surface. The outer peripheral concave surface has such a shape that a cross sectional shape thereof formed by a plane including a rotation axis of an impeller gradually changes in the circumferential direction.

Abstract: In a compressor (11) of a turbocharger (1), a compressor wheel (14) is provided in a housing (12) to be capable of rotating. When the wheel (14) rotates, air suctioned through an inlet of the housing (12) is compressed and then discharged through an outlet of the housing, (12). Further, an abradable seal layer (16) formed on an inner surface of the housing (12) is abraded by a vane (13) of the rotating wheel (14) such that a tip clearance between the vane (13) and a part of the inner surface of the housing (12) that opposes the vane (13) is adjusted. A corner portion (13a) of the vane (13) on the outlet side of the housing (12) is shaped to move gradually further away from a shroud curve (Lc) of the seal layer (16) toward an end portion of the vane (13) on the outlet side of the housing (12).

Abstract: A compressor housing is provided with a scroll piece that includes a cylindrical intake port forming section that forms an intake port, a scroll wall surface forming section that forms an air-intake side wall surface of a discharge scroll chamber, and a scroll outer circumferential section that covers an outer circumferential side of the discharge scroll chamber; a shroud piece that includes a cylindrical shroud press fitted section press fitted into the intake port forming section, and a shroud wall surface forming section that forms an inner circumferential side wall surface of the discharge scroll chamber and also forms a shroud surface that opposes an impeller and a diffuser surface; and an outer circumferential annular piece that includes an outer circumferential annular press fitted section that is press fitted inside the scroll outer circumferential section, and an outer circumferential annular wall surface forming section that forms an outer circumferential side wall surface of the discharge scroll ch

Abstract: The present disclosure relates to a method of inhibiting a fat accumulation for a fat cell in a subject, which includes administering a fat accumulation inhibitor for a fat cell which includes a milk-derived phospholipid as an active ingredient to the subject. The present disclosure also relates to a method of inhibiting a visceral fat accumulation in a subject, which includes administering the visceral fat accumulation inhibitor which includes a sphingosine-containing phospholipid as an active ingredient to the subject. The present disclosure also relates to a method of accelerating increase and/or inhibiting decrease of an adiponectin concentration in blood, which includes administering an agent which includes a sphingosine-containing phospholipid as an active ingredient to the blood. The present disclosure also relates to a method of inhibiting a fat accumulation for a fat cell in a subject, which includes administering a milk-derived phospholipid to a subject.

Abstract: A turbocharger includes: a turbine wheel that is driven by exhaust gas from an engine and supported rotatably by a predetermined rotary shaft; and a turbine housing that forms an exhaust gas passage that leads the exhaust gas to the turbine wheel, wherein the turbine housing includes a housing main body constituted by a plate-form member and a reinforcement member that forms the exhaust gas passage together with the housing main body and reinforces the housing main body, the reinforcement member includes a pair of annular portions having a substantially annular shape and provided about an axial center of the rotary shaft at an interval in an axial direction of the rotary shaft, and a connecting portion that connects the pair of annular portions, and the pair of annular portions and the connecting portion are molded integrally by implementing deformation processing on the plate-form member.

Abstract: Disclosed is a liver function-protecting agent which comprises a phospholipid as an active ingredient, and which can exhibit an excellent prophylactic and ameliorating effect on the deterioration in the liver function when ingested orally. Also disclosed is a liver function-protecting food, beverage or feed. The phospholipid is preferably one derived from milk or a milk material. Alternatively, the phospholipid may be used in the form of a phospholipid-containing composition prepared from milk or a milk material and containing the phospholipid in an amount of 10 wt % or more relative to the total solid content.

Abstract: To provide a fat accumulation inhibitor and a food or drink for inhibiting fat accumulation, a visceral fat accumulation inhibitor and a food or drink for inhibiting visceral fat accumulation, or an agent for accelerating increase and/or inhibiting decrease of an adiponectin concentration in blood and a food or drink for accelerating increase and/or inhibiting decrease of an adiponectin concentration in blood. A fat accumulation inhibitor for a fat cell, which comprises a milk-derived phospholipid as an active ingredient, and a food or drink for inhibiting fat accumulation in a fat cell, which comprises a milk-derived phospholipid. A visceral fat accumulation inhibitor comprising a sphingosine-containing phospholipid or a derivative thereof as an active ingredient, and a food or drink for inhibiting visceral fat accumulation.

Abstract: A turbocharger having a variable nozzle mechanism, which is accommodated in an accommodating chamber, is disclosed. The variable nozzle mechanism has a nozzle ring, a nozzle vane, a nozzle vane drive mechanism, and a support ring. The nozzle ring defines a gas passage through which exhaust gas is guided to a turbine wheel. The nozzle vane is supported by the nozzle ring and varies the flow area of the gas passage. The nozzle vane drive mechanism drives the nozzle vane. The support ring is connected to the nozzle ring. The nozzle vane drive mechanism is accommodated in the accommodating chamber as spaced from the nozzle ring through the support ring. The turbocharger has a drain passage that extends through a lower portion of the support ring and reaches the gas passage. The drain passage is located downward from the nozzle vane drive mechanism.
