摘要:
A communication device transmits a first packet to a first device via a network device, and receives a second packet from the first device. A transmission time between the communication device and the first device is calculated using time indicated by the communication device when the communication device transmitted the first packet, time indicated by the first device when the first device received the first packet, time indicated by the first device when the first device transmitted the second packet, time indicated by the communication device when the communication device received the second packet. A size of the first packet is set so that wait time of the first packet at the network device is within predetermined period. The wait time is calculated by assuming that a third packet transmitted from a second device is inputted to the network device before the first packet is inputted to the network device.

Disclosed is a means for improving the poor conversion efficiency in a conventional bioconversion system using a transformant which is given by introducing a gene originated from xerogenic organisms. A transformant is prepared by using a host which is defective in a gene encoding a multidrug efflux protein and introducing a gene originated from xerogenic organisms. Use of the transformant results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound. In case, an Escherichia coli is used as the host, the gene encoding a multidrug efflux protein to be defective may be tolC, acrA, acrB and the like.

In a method for manufacturing a spectral module 1, a photodetecting unit 10 constructed by bonding a photodetector 5 and a light transmitting plate 56 together is attached to a front face 2a of a substrate 2 by an optical resin agent 63. Here, a light transmitting hole 50 of the photodetector 5 is covered with a light transmitting plate 56, whereby the optical resin agent 63 is prevented from intruding into the light transmitting hole 50. When preparing the photodetecting unit 10, a semiconductor substrate 91 provided with a photodetecting section 5a and the light transmitting plate 56 are bonded together, and then the semiconductor substrate 91 is formed with the light transmitting hole 50, whereby matters which may cause refraction, scattering, and the like to occur can reliably be prevented from intruding into the light transmitting hole 50.

Disclosed is a means for improving the poor conversion efficiency in a bioconversion system using an Escherichia coli cell having a bacterium-originated cytochrome P-450 gene integrated therein. A recombinant Escherichia coli cell is produced by introducing aciB and aciC which encode a gene for the electron transport system originated from the Acinetobacter sp. OC4 strain into an Escherichia coli cell, and adding a polynucleotide encoding an N-terminal sequence composed of 48 amino acid residues of AciA and the like to the 5′-terminus of a bacterium-originated cytochrome P-450 gene, wherein AciA is an alkane-oxidative cytochrome P-450 originated from the Acinetobacter sp. OC4 strain. Use of the recombinant Escherichia coli cell results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound.

The present invention provides a nonwoven fabric for cylindrical bag filter, wherein a long-fiber nonwoven fabric made of a synthetic fiber is used and the long-fiber nonwoven fabric is a long-fiber nonwoven fabric which is made of a thermoplastic continuous filament and is partially thermocompression-bonded. It is preferable that the circular arc flexural rigidity per basis weight is 0.050 to 1.000 ((cN/2 cm)/(g/m2)) and the air permeation rate per basis weight is 0.010 to 0.500 ((cc/cm2/sec)/(g/m2)). Further, there is provided a method for producing a nonwoven fabric for cylindrical bag filter including the steps of: melt-extruding a thermoplastic polymer through a spinneret; sucking and drawing the extrudate with an air sucker to form a thermoplastic continuous filament; allowing the filament to be subjected to electrification opening and to be piled on a moving collection surface to form a fiber web; and allowing the fiber web to be subjected to pressure welding treatment with a flat roll and partially thermocompression-bonding the fiber web with hot embossing rolls to form a long-fiber nonwoven fabric.
