摘要:
A crystallization device is for protein crystallization with a small amount of a sample in the liquid to liquid diffusion method. It is easy to fill the device with protein solution and precipitant solution and easy to pick up grown crystals from the device. The device comprises a channel plate made of polydimethylsiloxane (PDMS) and the first and second cover sheets made of polyethylene terephthalate. The channel plate includes at least one elongated channel having one side which extends in the longitudinal direction of the channel, the one side being exposed at the bottom surface of the channel plate. The channel has both ends which communicate with a protein solution inlet and a precipitant solution inlet respectively. The channel also communicates midway with a gel inlet and a vent hole. When picking up grown crystals from the device, the second cover sheet is cut off with a cutter knife so that the channel is exposed.

A radiation detector includes two radiation conversion panels for detecting radiation image information representing a radiation image of a subject. A signal combination judging circuit judges a combination of two serial signals representing the detected radiation image information. Based on the judged combination, an amplitude/phase modulator modulates the serial signal into an amplitude-modulated signal and modulates the phase of the amplitude-modulated signal according to the other serial signal, generating an amplitude/phase-modulated signal. The amplitude/phase-modulated signal is transmitted through an optical fiber to a console.

A crucible has a structure where a layer containing a crystallization accelerating component such as aluminum or the like (a crystallization accelerating layer) is inserted inside a quartz glass layer of a crucible straight body part excepting a crucible bottom part. The crucible does not deform and fall inwardly at the straight body part since a part containing a crystallization accelerating component advances to crystallize so as to increase strength at a high temperature when the crucible is used in pulling up silicon single crystal. Therefore, a single crystallization rate can be increased. Further, since the crystallization accelerating layer is inserted inside the quartz glass layer, the crystallization accelerating component, such as aluminum or barium, does not contact with silicon melt or a carbon susceptor, contamination by eluting these metals does not occurs. Further, since the crystallization accelerating layer is not provided at the crucible bottom part, there is no danger to crack due to thermal distortion at a time of pulling up silicon single crystal and melt leakage does not occur.

The present invention provides a process for producing a dipeptide other than D-alanyl-D-alanine and D-alanyl-D-serine using, as an enzyme source, a culture of a microorganism having the ability to produce a protein having D-alanine-D-alanine ligase activity or a treated matter of the culture, and a process for producing a dipeptide comprising D-amino acid using, as enzyme sources, a culture of a microorganism having the ability to produce the D-amino acid or a treated matter of the culture and a culture of a microorganism having the ability to produce a protein having D-alanine-D-alanine ligase activity or a treated matter of the culture.
摘要:
A processing unit (processor) performs processing of programs. A monitoring unit measures the rate of operation of an instruction processor in the processing unit. Information which is a standard for judging modification of the performance is stored in a control information memory unit. A control unit judges on the basis of the operation rate of the processor collected by the monitoring unit and the control information stored in the control information memory unit whether it is necessary to modify the performance or not and controls to modify the performance of the processor on the basis of the judged result.
摘要:
Lengths of arms of pressing members held at a lower end of an arm section of a cover member are determined in correspondence to the retention of semiconductor devices having contour dimensions different from each other, and are shorter than a length of the arm section so that part of the pressing members is projected outside through a recess of the socket body.
摘要:
A virtual machine system is constructed between a plurality of real machines of a multiprocessor system. In order to move a virtual machine operating in a virtual machine system on a given real machine to a virtual machine system on another real machine, each virtual machine system is managed by attaching a common logic name to the real machine resources. The origin of the virtual machine (VM) is notified of the logic name of the real resource corresponding to the VM configuration information. The destination VM includes a device for generating an identical VM configuration according to the logic name received thereby to realize the movement of the VM configuration. Also, the origin VM holds a new asynchronous operation request for the VM to be moved, and suspends the operation of the VM. The VM resource information and the asynchronous operation hold information are transferred to the destination. The destination VM restarts the VM operation in accordance with the received information.
