摘要:
Chitin-containing material is heat-treated in organic solvent or in the solvent with water, and then .beta.-1, 4 glycoside decomposing enzyme is added for decomposing the chitin-containing material by enzyme reaction. Or, chitin-containing material is ultrasonicated in organic solvent or in the solvent with water, and then chitin-containing material is decomposed by enzyme reaction of .beta.-1, 4 glycoside decomposing enzyme. Further, chitin-containing material is exposed in the solution containing urea and/or surfactant, and then chitin-containing material is let co-exist with .beta.-1, 4 glycoside decomposing enzyme under the presence or non-presence of urea and/or surfactant for decomposing chitin-containing material. Or, at the time of exposing chitin-containing material in the solution containing urea and/or surfactant, the solution is heated and the .beta.-1, 4 glycoside decomposing enzyme is added for decomposing chitin-containing material.
摘要:
A timing clock extraction circuit for extracting from a multilevel code signal, transmitted at a predetermined baud rate, in which cross timings with a reference level are generated at frequency timings several times the baud rate, a clock pulse train at the baud rate and obtaining discriminative data from the multilevel code signal in accordance with the extracted clock pulse train. The timing clock extraction circuit includes a detector for detecting cross timings between the multilevel code signal and a predetermined threshold value; a synchronization control circuit for outputting a clock pulse train having a frequency several times said baud rate in synchronism with the cross timings; a clock generator for dividing the several-time clock pulses to generate a plurality of trains of baud rate clock pulses in different phase from each other; and a decision unit for distinguishing a baud rate clock pulse train from the plurality of trains of baud rate clock pulses which are synchronized with discriminative points of the multilevel code signal by using the cross timings and the clock pulse train having a frequency several times the baud rate.

A duplex data processing system includes two processors each provided with a bus connecting unit which disconnects the associated CPU bus from the cross connection bus in a separate mode or connects the CPU bus to the cross connection bus in a duplex mode. The system operates with a logically unified CPU bus through the connection of the internal CPU buses by the two bus connecting units in both processors.

A time division exchange provided with a plurality of compression circuits for carrying out signal compression in accordance with a plurality of compression laws and a plurality of expansion circuits for carrying out signal expansion in accordance with a plurality of expansion laws is operated in the following manner. In a case where the exchange is used as an originating exchange, a compression circuit provided in the originating exchange for carrying out signal compression according to a desired compression law is selectively used at each time slot, and information on the desired compression law is sent out from the originating exchange. Further, in a case where the exchange is used as a destination exchange, an expansion law to be used on the receiving side is selected on the basis of the above information, and an expansion circuit provided in the destination exchange for carrying out signal expansion according to the selected expansion law is selectively used at each time slot.

Side guides for rolling steel rods comprise front and rear rolling guide frames consisting of partitions abuttingly connected to each other in a gap between a pair of rolls having cylindrical surface barrels to form defined rolling zones which are side by side along the roll barrels and divided by the partitions and capable of retaining steel rods being rolled, thereby effectively carrying out rolling of steel rods with grooveless rolls without using calibers without twisting and deforming the steel rods into incorrect cross-sections.
摘要:
A process for determining a bacterial endotoxin, which comprises contacting an assay sample with (A) a material selected from the group consisting of an amoebocyte lysate of horseshoe crab an a pro-clotting enzyme separated from the lysate, and (B) a peptide-type substrate of the formula (R.sub.1 --Gly--Arg--R.sub.2), wherein R.sub.1 represents a member selected from the group consisting of an L-amino acid moiety whose N-terminal is protected by a protective group, a peptide moiety consisting of an L-amino acid and protected by a protective group at its N-terminal, a D-amino acid substituted L-amino acid moiety, and a D-amino acid substituted peptide moiety consisting of an L-amino acid, and is bonded to the amino group of the glycine moiety expressed by Gly through a peptide bond; and R.sub.2 represents a moiety which is bonded to the C-terminal of an L-arginine moiety expressed by Arg through an acid amide bond and/or ester bond and can be enzymatically hydrolyzed in the presence of the material (A) and the endotoxin to liberate R.sub.2 H, and/or its mineral acid salt, and detecting the resulting R.sub.2 H in which R.sub.2 is as defined above; and the above reagent used therefor.
摘要:
A developer case has a main body, a cylindrical portion, and a rotating unit. The main body has a bottom wall. The cylindrical portion has a discharge port. The rotating unit is located so as to extend across the main body and the cylindrical portion, transports developer in the main body, and has a rotating shaft, a first transport member, a second transport member, and dispersing members. The rotating shaft has a first portion located in the main body and a second portion located in the cylindrical portion. The first transport member transports developer in a first transport direction from the cylindrical portion to the main body. The second transport member transports developer in a second transport direction from the main body to the cylindrical portion. The dispersing members move developer in the radial direction.

A mobile communication system according to the present invention includes the steps of: causing an UE to switch a radio access network in a connection destination from E-UTRAN to UTRAN/GERAN; causing an MME to receive “Delete Bearer Request” to a voice communication packet bearer from an S-GW; and causing the MME to transmit to the S-GW a “Delete Bearer Response” to the “Delete Bearer Request”, without giving an instruction to the UE#1 or the E-UTRAN to release the voice communication packet bearer, if a core bearer disconnection flag is set in the received “Delete Bearer Request”.
摘要:
A component measurement device, namely a blood-glucose measurement device, that has a measurement unit that focuses measurement light on a test paper through an illumination lens and receives reflected light from the test paper. The blood-glucose measurement device measures blood components on the basis of results from detecting the reflected light. The illumination lens is provided in the measurement unit such that the focal point of the measurement light is beyond the test paper.
