The communication performance of a radio communication system is improved while keeping short time necessary for attaining synchronization. A low noise amplifier is selectively provided with one of an input signal supplied from the outside of the system and an oscillation output signal of a local oscillator. A mixer integrates the oscillation output signal of the local oscillator and an output signal of the low noise amplifier. An intensity discriminating unit discriminates the signal intensity of an output of the mixer. In a first state, the low noise amplifier amplifies the oscillation output signal of the local oscillator, and a control unit learns a frequency band of the low noise amplifier for maximizing the signal intensity on the basis of the discrimination result of the intensity discriminating unit. In a second state, the low noise amplifier is set to the frequency band learned in the first state and amplifies the input signal.

The magnetoresistance is measured for a magnetoresistive layered-structure, such as a spin valve film, prior to formation of an upper shield layer as well as patterning of a lower shield layer. The magnetic influence of the upper and lower shield layers can completely be eliminated during the measurement of the magnetoresistance. The magnetoresistive layered-structure is allowed to reliably receive the magnetic field over a wider range including a lower magnetic field range. It is accordingly possible to measure the magnetoresistance properly reflecting the magnetic characteristic of the magnetoresistive layered-structure. It is possible to find deficiency of a magnetoresistive read element at an earlier stage of the method.

A flat-panel display device includes a matrix array of display pixels which respectively have memory elements, a vertical decoder which selectively designates row blocks of the display pixels, a horizontal decoder which selectively designates column blocks of the display pixels, a video RAM which stores image data respectively assigned to the memory elements, and a controller which controls the vertical and horizontal decoders to write the contents of the video RAM in units of blocks specified by row and column block addresses. The device further includes an interface which determines a rewriting range corresponding to at least one block of the display pixels including display pixels for part of the image data when the part is updated in the video RAM, and supplies to the controller the image data assigned to each block included in the rewriting range.

A signal light passes through an isolator, and is coupled by a coupler with a pump light from a pump light source. Then, the signal light passes through an ASE reflection filter, is amplified by an EDF, and is transmitted from an isolator. At this time, an ASE light having a predetermined wavelength among ASE lights that occur within the EDF and proceed to the ASE reflection filter is reflected and again input to the EDF. By setting the predetermined wavelength to a wavelength on the short wavelength side of an amplification band of the EDF, gain deviation occurring on the long wavelength side of the amplification band can be cancelled.

An intelligent power module (IPM) is formed of an inverter having power elements, a predriver for driving the inverter, and a protect circuit, and all these components are integrated into the same package. A shunt resistor is provided at an output of the inverter so that an end-to-end voltage of the shunt resistor can be output to an external device. This configuration enables an output current from an inverter apparatus incorporating the IPM to be detected without using a current transformer that requires a large installation space. In addition, the module terminals of the IPM and the terminal blocks of the inverter apparatus are integrated together to eliminate the need for wire rods and set screws for connections which are used to connect the module terminals and the terminal blocks together.

A method for transforming strain PF1022, which produces a cyclic depsipeptide (substance PF1022) and belongs to the order Agonomycetales of the class Hyphomycetes has been established by using a plasmid constructed with a promoter, a terminator, a marker gene and a target gene. When the strain PF1022 was transformed by this method, a gene encoding an enzyme, which is the target gene, was transduced into the host. As a result, the utilization of nutrients by the strain PF1022 was improved and, further, its cyclic depsipeptide productivity was also improved.

A control system for a vehicular drive unit having an engine, a motor-generator for acting as a motor and a generator; a power transmission including a planetary gear composed of at least three rotary elements and a mechanism for selectively connecting/releasing the rotary elements; a battery for storing electric power generated by the motor-generator and for supplying a driving electric power; a residue detector for detecting the state of charge of the battery; and a controller for controlling the engine, the motor-generator and the connecting/releasing mechanism in accordance with an output signal from the residue detector. The first rotary element of the planetary gear is connected to the output shaft of the engine; the second rotary element, as acting a reaction against the first rotary element, is connected to the motor-generator; and the third rotary element is connected to an output member for transmitting the drive power to wheels. The controller includes mode switching capability for switching the mode when the battery is in an ordinary state or in a low charge state, to a power split mode, in which the motor-generator outputs a reaction torque against the output torque of the engine so that the connecting/releasing mechanism can rotate the first, second and third rotary elements individually and, when the battery is in a full charge state, to a parallel hybrid mode, in which the motor-generator adds a torque to the output torque of the engine so that the connecting/releasing mechanism can rotate the first and second rotary elements together.
