A sliding bearing 4 is constructed by an upper split bearing half 8 and a lower split bearing half 9. The upper split bearing half 8 has a sliding surface 8a, in which an oil groove 10 which allows an lubricating oil to flow therein is formed over the entire circumferential extent of the sliding surface 8a. The oil groove extends through a crush relief 8c to be open to a junction area 8b, and the oil groove has a bottom 10a which is formed so that a portion disposed toward the junction area as considered in the circumferential direction of the crush relief is located closer to the center of the upper split bearing half in comparison to a central portion. An ingress in large quantities of foreign particles within the oil groove onto the sliding surface of the sliding bearing and into a connecting rod bearing after passing through a lubricating oil feed passage is suppressed, and an oil leakage through the crush relief is reduced, allowing a lubricating oil pressure to be secured and augmented.

A system is provided for supporting one or more objects above an operating surface. A central frame extends upwardly from a base and supports one or more attachment members for supporting a variety of objects. In one aspect the objects supported by the system are targets that receive striking forces from external sources. A force measuring device may be associated with the targets. The central frame may be adjustable so that the height of the objects supported by the system may be varied. The base may include stabilizer members that are movable between collapsed and extended positions. Weight of various types may be associated with the stabilizer members to promote stability of the system. Wheels may be associated with the base to enable transport of the system from one location to another.

Provided is an air blowing device capable of keeping an air outlet invisible to the extent possible without impairing a function as the air blowing device. An air blowing device (10) includes: a tubular body (21) defining an airflow passage (21a) and an air outlet (21b); a guide wall (31) for guiding an airflow having passed through the air outlet in an intended direction; and a flow velocity adjusting mechanism (valve body) (22) capable of adjusting a flow velocity of the airflow passing through the air outlet. The guide wall has a convex surface shape protruding in a direction intersecting with a forward direction of the air outlet, and is arranged so that a projection image, which is obtained by projecting the guide wall onto an imaginary plane including the air outlet, covers the entire air outlet. The flow velocity adjusting mechanism is configured to adjust the flow velocity in accordance with the intended direction.

A biochemical reaction cassette having a structure for uniformizing a liquid flow in a reaction chamber with a simple additional arrangement is provided. A fluid resistive section is arranged in a channel that is constructed to include an injection port, a reaction chamber, and a discharge port. The fluid resistive section decreases the cross-sectional area of the channel to decrease the fluid resistance at ends in the width direction of the fluid resistive section and at positions remote from the injection port and the discharge port, where the flow rate is decreased.

A rectifying module is arranged on an upstream side of a flow passage containing a flow velocity sensor. The rectifying module includes mesh members each having a plurality of circular small holes and ring-shaped spacers, wherein the mesh members and the spacers are alternately stacked in an axial direction and integrally joined to one another by means of thermal diffusion bonding. The mesh members have identical structures, in which the plurality of small holes are arranged concentrically at angles of separation of 60 degrees in the circumferential direction about the center of a reference small hole. The small holes are formed over the entire surface of the mesh member continuous with adjoining other small holes. The small holes of one mesh member and another mesh member adjacent thereto in the axial direction are arranged so as to have a phase angle difference of 90 degrees in the circumferential direction.

The invention relates to a bridge suspension and steel bar type stereo garage. The purpose of the invention is to overcome the shortcomings of a current garage by providing a new bridge suspension stereo garage that can be manufactured at a low cost and provide good performances. The stereo garbage can also be of less labor intensity and can be mounted and maintained very conveniently. The second-tier lifting mechanism is a structure made of steel ropes and rolling cylinders; the bottom layer is provided with a completely natural parking stall without a car loading plate or a lateral movement stall; the second tier is a lateral moving parking stall either lifted to the left or to the right; through the bridge suspension steel bar, a small car can be laterally moved to a path to enter or exit from. This means that the car can advance to not only park but also leave without having to be reversed to enter a parking stall. As a result, car parking becomes easier. More particularly, for an underground parking lot provided with a two-tier stereo garage, the space of parking stalls at the left group and the right group of the two tiers are in full use for cars to enter and exit, thus saving a great area of a path. And at the same time, other vehicles on the main path can pass without being impacted.

A constant flow regulator device for maintaining a constant flow of fluid when a variable fluid pressure is applied, comprising an inlet duct ( 506 ) for incoming fluid, a housing ( 500 ), and a movable partition ( 502 ) facing the inlet duct and being subjected to an elastic force. A fluid passage ( 510 ) of variable cross section area is formed between the inlet duct and the movable partition. The housing and movable partition form an inner compartment ( 504 ) in fluid communication with the inlet duct for establishing a fluid pressure inside the inner compartment approximately equal to the fluid pressure in the inlet duct. The size of the movable partition is significantly greater than the size of the inlet duct such that, in use, the partition is moved towards the inlet duct against the elastic force when the fluid pressure in the inlet duct increases to reduce said fluid passage cross section area, and vice versa, thereby maintaining constant fluid flow.

A turbine stator vane or turbine rotor vane has a body, a channel being adapted for leading a cooling fluid through the body, and a flow adaption feature protruding from the body to the channel in such a manner as to reduce a cross-sectional area of the channel.
