摘要:
A system and apparatus for controlling the operation of a vibrating compressor using a predetermined frequency corresponding to the load thereof, comprising a first sensor for detecting a temperature of pressure corresponding to the saturated vapor pressure of a refrigerant sucked by a vibrating compressor, a second sensor for detecting a temperature or pressure corresponding to the saturated vapor pressure of the refrigerant compressed and discharged by the compressor, and a control section for generating a drive power of a predetermined frequency based on the temperatures and pressures detected by the first and second sensors, and characterized in that the compressor is driven by a drive power generated by the control section. In the present invention, the operation of the vibrating compressor can be controlled at the maximum efficiency by relating the frequency of an alternating current power fed to the vibrating compressor with the suction temperature or pressure and the discharge temperature of pressure of the refrigerant.

An ultrasonic inspection apparatus obtains information on the interface of a sample as digital waveform data for any “unit measurement range” and is provided with at least two data memories and controlled by a scan state monitoring signal showing the scan state of a unit measurement range belonging to a first group or a unit measurement range belonging to a second group. A comparator-register/memory-control-circuit outputs the scan state monitoring signal to the two data memories. The operating states of the two data memories being controlled by the scan state monitoring signal to alternate between writing of digital waveform data and readout of digital waveform data.

Known cell lines derived from silkworm exhibit low propagation efficiency of BmNPV. Accordingly, systems using known culture cell lines derived from silkworms take a long time to establish recombinant viruses, and are not suitable for preparation of virus solutions with high titers. The present invention provides a cell line Bme21 (FERM P-20852) that is derived from a silkworm embryo and is highly susceptible to BmNPV or its variant having the same biological characteristics. The present invention also provides a method of producing a recombinant virus, a method of producing a recombinant protein, a method of increasing efficiency of recombinant virus production, and a method of increasing efficiency of recombinant protein production, using the cell line Bme21 or its variant.
摘要:
A vibrating compressor having a housing with an inner tube and an outer tube formed concentrically. The inner tube is connected with the outer tube via an end plate. The end plate being disposed at one axial end of the inner tube and the outer tube to form a housing closed end and a housing open end. A permanent magnet is fitted to an inner circumferential surface of the outer tube. A driving coil is provided in a gap between the permanent magnet and the inner tube. A cylinder is fitted into an inside of the inner tube and a hollow piston equipped with a valve is inserted into the cylinder. The hollow piston is connected to the driving coil via a bobbin and is supported by support springs in such a manner as to perform reciprocating motion. A cylinder head connected to the housing forms a compression chamber at an end of the cylinder and compressed fluid is discharged from the compression chamber by the reciprocating motion of the piston. First and second cover plates are disposed at opposite ends of the housing to form a sealed container with the housing.
