Abstract: A process for producing a benzhydrol compound (II) which comprises hydrogenating a benzophenone compound (I) in the presence of a hydrogenation catalyst consisting of a transition metal complex, a base and an optically active diamine compound:
     
      wherein R 1  to R 10  each represents H, OH, C 1-4  alkyl, C 1-4  alkoxy, C 1-4  alkanoyl, etc., R 2  and R 3 , and R 8  and R 9  may form -CH=CH-CH=CH-, or any two of R 1  to R 9  adjacent to each other may be bonded to thereby form -OCH 2 O- or -(CH 2 ) 3 -. By using this process, optically active benzhydrol compounds which have a high purity and are useful as, for example, intermediates in the synthesis of drugs can be produced by simple procedures.

Abstract: The recuperator has an inner tube, an outer tube and a heat-conducting intermediate tube (1). The wall of the intermediate tube bulges at various places over its length and round its circumference to produce outward (5) and inward (6) knobs. These knobs increase the heat transmission surface of the intermediate tube. A narrowing of the flow path adjacent to a widening of it is formed between adjacent knobs. This alternately expands and compresses the fluid, reducing the boundary layer build-up.

Abstract: The invention provides a method which achieves reduction of virtual channel connection delay time involved in signaling without using virtual channels as permanent virtual channels (PVC) and without performing wasteful allocation of a signal bandwidth and of a signaling system. In the signaling system, when transmission terminal 100 transmits a packet, packet transmission control section 110 delivers a request for transmission of a packet to signaling transmission section 101. Upon reception of the request, signaling transmission section 101 searches VC and signal bandwidth table 102 and sends out, when a virtual channel is registered and a necessary signal bandwidth is held, a packet using the virtual channel, but requests, when a virtual channel is registered but the signal bandwidth is short, a packet switching system only for a signal bandwidth and then sends out the packet by way of the virtual channel. On the other hand, when no virtual channel is registered; signaling transmission section 101 delivers signaling to request transmission of the next packet to the packet switching system. Table 102 includes, for each destination address, virtual channel timer 112 for release the virtual channel applied thereto after the virtual channel is held for a predetermined period of time after it becomes free, and bandwidth timer 111 for reducing the signal bandwidth after each predetermined interval of time after the virtual channel becomes free. Each end of a packet transmission, the two timers are reset to clock.

Abstract: A method and mechanism for aligning a fixed scroll member relative to a
main bearing member in a scroll compressor. A shoulder is machined on the outer
perimeter of a main bearing member and interfits with an arcuate lip on the fixed

the arcuate lip of the fixed scroll member and receives a projecting pin disposed on
the main bearing member when the fixed scroll is assembled to the main bearing
member. Relative rotation of the fixed scroll member and main bearing member
brings one edge of the projecting pin into engagement with an abutment surface
defining one end of the notch and thereby properly rotationally positioning the fixed
scroll member. The fixed scroll member is subsequently axially secured to the main
bearing member with a plurality of bolts.
