Abstract: A hydrogen transfer reaction may be more efficiently promoted by using a metal complex represented by Formula (2): (wherein, R1 to R8 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group or the like; or wherein; R1 and R2, R2 and R3, R3 and R4, R4 and R5, and R5 and R6 are respectively bonded to each other to form a bivalent hydrocarbon group; R9 are the same or different, and each represents an alkyl group or cycloalkyl group; M is ruthenium (Ru) or the like; X is a ligand; and n is 0, 1 or 2). More specifically, the metal complex enables a hydrogenation reaction of various substrates having a stable carbonyl group or the like to be advanced with a high yield under mild conditions.

Abstract: A drive transmission mechanism for transmitting torque between two or more rotary shafts in synchronization with one another without need for lubrication thereby eliminating occurrence of oil contamination, and an oil-free fluid machine equipped with the mechanism, are provided. A magnetic drive disk and a synchronization gear are attached to a rotary shaft connected to a drive motor, a magnetic drive disk and a synchronization gear is attached to a rotary shaft, torque transmission from the rotary shaft to the rotary shaft is carried out in two ways, via the magnetic drive disks and via the synchronization gears and at least one of the synchronization gears is made of plastic material. With the construction, torque transmit load between the rotary shafts via the synchronization gears is decreased, and a plastic gear or gears can be adopted for synchronization gears without reducing life of the gears without need for lubrication oil.

Abstract: In a scroll fluid machine, a driving shaft extends axially to allow an orbiting scroll to revolve with respect to a fixed scroll thereby compressing a gas introduced from the outer circumference of the fixed scroll in a compressing chamber formed between the orbiting and fixed scrolls. From one end of the driving shaft, external air is introduced in a cooling hole extending axially of the driving shaft to cool the driving shaft. A cooling fan is rotatably secured at one end of the driving shaft to rotate by the driving shaft to cool the fixed scroll. The cooling fan comprises a base plate having a main fin on one side surface facing the side of the fixed scroll and a plurality of auxiliary fins on the other side surface to prevent cooling-finished air from invading into the cooling hole of the driving shaft.

Abstract: In a scroll fluid machine, a fixed scroll has a fixed wrap, and an orbiting scroll has an orbiting wrap which engages with the fixed wrap to form a compressing chamber between the orbiting and fixed wraps. The orbiting scroll is rotatably mounted around an eccentric axial portion of a driving shaft and revolved by the driving shaft. A gas introduced from the outer circumference of the fixed scroll is compressed in the compressing chamber as it flows towards the center. Parts near the center is heated by a compressed gas. On the other surface of the fixed scroll to the surface having the fixed wrap, a plurality of cooling fins are provided. Air is introduced between the cooling fins to cool the machine. Between the cooling fins, a heat-releasing projection is provided to improve cooling efficiency.

Abstract: In a scroll fluid machine, an orbiting scroll is eccentrically revolved with respect to a stationary scroll so that fluid in a sealed chamber between the stationary and orbiting scrolls may be compressed toward a center. A first magnet is mounted on the stationary scroll and a second magnet is mounted on the orbiting scroll so that the same poles of the first and second scrolls may be opposite to each other thereby preventing the orbiting scroll from pressing the stationary scroll excessively.
