摘要:
When FRET (Fluorescence Resonance Energy Transfer) detection of a large number of samples is performed in a short time for a sample consisting of a donor molecule and an acceptor molecule, the donor molecule is irradiated at first with first laser light used for exciting a donor molecule subjected to intensity modulation at a frequency of f+Δf, the accepter molecule is irradiated with second laser light used for exciting an acceptor molecule subjected to intensity modulation at a frequency of f, and fluorescence emitted from the accepter molecule is received. From a fluorescence signal thus received, a first signal component of fluorescence emitted from the accepter molecule through FRET, and a second signal component of fluorescence emitted from an accepter molecule excited through irradiation with the second laser light are extracted. Phase lags of the first and second signal components thus extracted are then calculated and the presence of generation of FRET is judged based on these phase lags.

A liquid sample flow containing living cells is irradiated with measurement laser light and the photo data of at least either scattering light or fluorescence that is generated by each of the living cells in the liquid sample flow due to the irradiation with the measurement laser light is acquired. Based on the photo data thus acquired, it is determined whether each of the cells assignable to the respective photo data is an unnecessary living cell or a target living cell. Based on the determination results, a pulse voltage is then applied exclusively to the living cells having been determined as unnecessary living cells so that the unnecessary living cells are damaged and killed.

A cable-stayed suspension bridge having characteristics of a cable stayed bridge and those of a suspension bridge at the same and time and using one-box and two-box girders in combination is disclosed. The bridge grinder of the cable-stayed suspension bridge includes one-box girders that each extend to both sides through the respective one tower and a two-box girder set in a central portion of the center span between towers in the length direction of the bridge girder. The cable-stayed suspension bridge includes cable-stayed structures in which a respective one of the one-box girders is supported by the tower with plural cables and a suspension structure in which the two-box girder is supported by the plural towers with two main cables and plural hanger ropes. The two-box girder has a central ventilation opening in the central portion as viewed in a transverse direction thereof. The hanger ropes in the suspension structure extend from the main cables almost perpendicularly, and their lower end portions are connected to the end portions in the transverse direction of the central ventilation opening or in the vicinity thereof.

A denitration process for removing nitrogen oxides contained in low-temperature exhaust gas at a high denitration rate; namely, a denitration process for reductively removing nitrogen oxides contained in an exhaust gas (x) containing nitrogen monoxide and sulfur dioxide. The process comprises a preliminary step 2 of partially oxidizing nitrogen monoxide in the exhaust gas to form nitrogen dioxide, a radical formation step 3 of adding a nitrogen compound and a hydrocarbon compound to a high-temperature zone 22 to form amine radicals (r), and a denitration step 4 of mixing the amine radicals (r) with the pretreated gas (p) containing nitrogen monoxide and nitrogen dioxide that was discharged from the preliminary step 2. As a result, nitrogen oxides in the exhaust gas (x) are reductively decomposed.

A hoisting device can be small-sized and energy can be saved. A hoisting device 10 according to the present invention has a hoist 30 and a control unit 32. The hoist 30 rotates a drum 12 having a wire 14 wound thereon by an oil pressure motor 42 rotatable in normal and reverse directions. To the oil pressure motor 42, operating oil is supplied from an oil pressure pump 44. The oil pressure pump 44 is a two-way discharge fixed capacity type, and rotated by a servomotor 46. An acceleration/displacement transducer 34 in the control unit 32 finds a moving direction and a moving speed of a wire hanging point in the vertical direction from an output signal of an acceleration sensor 24. The control unit 32 outputs a drive control signal of the servomotor 46 according to a paying-out speed or a rolling-up speed of the wire 14 offsetting the vertical motion of the wire hanging point caused by the heaving of a hull based on a speed instruction Vi of the paying-out or rolling-up speed of the wire, a detected signal of the acceleration sensor 24 and a detected signal of a wire speed sensor 26.

It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit 400 according to the present invention is provided with control units 420 (420a to 420d) respectively corresponding to a plurality of heating units 310 (310a to 310d). A phase detector 424d of the control unit 420d obtains a phase difference between an output current (heating coil current IL4) of an inverter 314d detected by a current transformer 160d and a reference signal outputted by a reference signal generating section 426, and inputs it to a drive control section 422d. The drive control section 422d adjusts an output timing (phase) of a gate pulse to be given to the inverter 314d so as to make a phase of the heating coil current IL4 of the inverter 314d coincide with a phase of the reference signal outputted by the reference signal generating section 426. A phase control section 334d controls a variable reactor 326d so as to make the phases of an output voltage and the output current (heating coil current IL4) of the inverter 314d coincide with each other, and improves a power factor of the inverter 314d. Each of the other control units 420a to 420c also performs the same control operation.
摘要:
The present invention has its object to obtain an SiC monitor wafer which can flatten the surface until particle detection is possible. SiC of a crystal system 3C is deposited on a substrate by a CVD (Chemical Vapor Deposition) method, and the SiC is detached from a substrate. After the SiC surface is flattened by using mechanical polishing alone or in combination with CMP (Chemo Mechanical Polishing), GCIB (Gas Cluster Ion Beam) is irradiated to the surface until the surface roughness becomes Ra=0.5 nm or less and the impurity density of the wafer surface becomes 1*1011 atoms/cm2 or less to produce the SiC monitor wafer.

The present invention has its object to make it possible to produce an α-SiC wafer with stability and good reproducibility at low cost without using a seed crystal substrate that is expensive and less available. In each of crucibles 11a, 11b, 11c, and so on, a β-SiC substrate 19 and an SiC raw material 17 are placed to face each other in close proximity. These crucibles are stacked in layers, and placed inside a radiation tube 40. The radiation tube 40 is heated by an induction heating coil 23, radiates radiation heat, and uniformly heats the crucibles 11a, 11b, 11c and so on. The SiC raw material in each of the crucibles is sublimated and recrystallized on a surface of the β-SiC substrate 19.
