Abstract: A shuttle vector is constructed by preparing a DNA region replicable in bacteria belonging to the genus Rhodococcus from a Rhodococcus-derived plasmid having the nucleotide sequence set forth as SEQ ID NO: 73 and a plasmid or its DNA fragment having the nucleotide sequence set forth as SEQ ID NO: 74, and a DNA region replicable in E. coli from an E. coli-derived plasmid or its DNA fragment. An aminoketone asymmetric reductase gene is inserted into the shuttle vector, transformants containing the vector are created, and the aminoketone asymmetric reductase and optically active aminoalcohols are produced.

Abstract: It is made possible to quantify MT1-MMP and to measure the enzymatic activity of MT1-MMP sensitively, accurately and quickly with simple operations and reagents. The MT1-MMP quantifications and the MT1-MMP enzymatic activity measurements can be carried out using quantitative immunoassays for MT1-MMP with anti-MT1-MMP Ab and reagents used therefor, further immunologically quantifying methods for a member selected from (i) MT1-MMP released and/or solubilized from cell membrane with a surfactant and/or a reducing agent and (ii) spontaneously solubilized MT1-MMP, reagents used therefor, solid-phased MT1-MMP, etc., thereby enabling the screening for a compound which promotes or inhibits the expression of MT1-MMP or a compound which promotes or inhibits the enzymatic activity of MT1-MMP, and facilitating the development and research for valuable pharmaceutical drugs. There are also provided a useful testing drug for cancer or cancer metastasis.

Abstract: A holographic resonant system includes a plurality of volume phase holograms superimposed on a single layer of photosensitive film. The volume phase holograms are oriented with respect to one another such that a first volume phase hologram selects an incoming light beam incident upon a surface of the holographic resonant system having a wavelength &lgr;playback and an angle of incidence &thgr;in and internally diffracts the incoming light beam to a second volume phase hologram. The second volume phase hologram then accepts the resulting diffracted light beam from the first volume phase hologram and diffracts the light beam to form an image reflected from the surface of the holographic resonant system at wavelength &lgr;playback and an angle &thgr;out. The result is a holographic resonant system that only permits light beams from a predetermined direction to illuminate the system, thereby reducing the effect of ambient light upon the system and thus increasing the contrast ratio of the image.

Abstract: A pre-amplifier circuit comprises an operation amplifier having a noninverting input terminal connected to a voice input terminal, a negative feedback circuit having a first resistor which is connected between an output terminal of the operation amplifier and an inverting input terminal of the operation amplifier, and a second resistor and a switching element which are connected in series between the inverting input terminal of the operation amplifier and a ground, an operating switch for switching a small signal input mode and a large signal input mode, and an on-off control circuit for bringing the switching element into an off state to operate the operation amplifier as a buffer circuit when the operating switch is switched to the large signal input mode, while bringing the switching element into an on state to operate the operation amplifier as an amplifier circuit when the operating switch is switched to the small signal input mode.

Abstract: A touch screen input device and method for use with a rear-mounted video output projection system incorporates a transparent sheet preferably having substantially parallel top and bottom surfaces as the touch screen panel. A rear-mounted light source projects light onto the rear surface of the touch screen panel, on which a diffusing surface is imposed, with the result that some of the light from the light source is totally internally reflected within the touch screen panel and is imaged by a rear-mounted video camera. When the front surface of the touch screen panel is touched by a finger or rubbery object, total internal reflection is interrupted and the video camera images the touch as a dark spot.

Abstract: A motor current flowing through an inverter-driven induction motor is detected when voltage is applied to the induction motor by the inverter operated under a certain condition on the basis of the vector control. The detected current is converted to two components of a current vector in a d-q coordinate system. Motor constants are calculated on the basis of a component in the d-coordinate axis of a voltage reference set for creating the certain condition and the two converted components of the motor current detected at that time, and control constants in a vector control apparatus for the inverter-driven induction motor are set or adjusted in accordance with the calculated motor constants. According to this invention, the control constants in the vector control apparatus can be easily set or adjusted.

Abstract: In induction motor driven by a voltage-type inverter, the torque current component is determined by detecting a primary current flowing to the induction motor. On the basis of the torque current component determined, the output voltage and frequency of the voltage-type inverter are controlled. Additionally, the rotational speed of the induction motor is estimated on the basis of the detected torque current component and the speed of the induction motor is controlled such that the estimated speed signal coincides with a speed command signal.

Abstract: When an induction motor is speed-controlled with a variable frequency power supply including thyristor inverters, operating loss due to harmonics components is increased in a rotor of the induction motor. In order to diverge additional operating loss into an appreciable depth of the rotor to thereby suppress the increase in the operating loss, the rotor comprises a cylindrical member having a circumferential resistivity which is larger than axial and radial resistivities and circumferential permeability which is smaller than axial and radial permeabilities, and a core disposed in the cylindrical member and having an axial permeability which is smaller than circumferential and radial permeabilities.
