Abstract: Providing a microscope capable of movably adjusting an observation field of a sample without moving the sample. The microscope includes a first objective lens, a second objective lens, a mirror, an angular adjustment mechanism, and a shift mechanism. The first objective lens is disposed to the sample side. The second objective lens forms an intermediate image of the sample together with the first objective lens. The mirror is disposed with a tilt on an optical path between the first objective lens and the second objective lens. The angular adjustment mechanism rotatably adjust the mirror in the tilt direction. The shift mechanism makes a shift adjustment of the second objective lens in an axial direction of a rotation axis of the mirror. With the configuration, the observation field can be moved two-dimensionally by the angular adjustment mechanism.

Abstract: An inverted microscope has a microscope base, a stage, an observation optical system, a stage support structure which is arranged on the microscope base and supports the stage, and a switching structure having a plurality of objective lenses and capable of inserting one of the objective lenses into an optical path of the observation optical system selectively. A support structure is fixed to a lower surface of the stage and supports the switching structure for movement in an optical axis direction of the objective lens inserted in the optical path of the observation optical system.

Abstract: An inverted microscope has a microscope base, a stage, an observation optical system having an objective lens, a stage support member which is arranged on the microscope base and supports the stage at two ends, and a change member which can change the level position of the stage with respect to the microscope base.

Abstract: Fermented milk with a controlled acidity increase during storage and transportation is disclosed. The fermented milk can be manufactured by inoculating raw milk with a nisin-producing lactic acid bacterium belonging to the genus Lactococcus lactis subsp. lactis together with other lactic acid bacteria to be used for the fermentation and fermenting the raw milk. Nisin produced and accumulated in the fermented milk suppresses the growth of bacteria which are involved in the formation of acids, thus controlling the acidity increase during storage and transportation.

Abstract: Disclosed herein are Streptococcus salivarius subsp. thermophilus and variants thereof capable of producing an antibacterial substance which is a peptide or protein or a conjugate thereof, the antibacterial substance produced by the bacteria, and processes for producing fermented milk by using any one of the bacteria as a starter. The lactic acid bacteria produce the antibacterial substance, so that use of any one of the lactic acid bacteria as a starter for fermented milk inhibits growth of another lactic-acid-forming lactic acid bacteria also used as a starter owing to the antibacterial substance produced during fermentation. It is therefore possible to suppress the formation of the acid during storage or transportation of fermented milk, thereby making it possible to prevent taste and flavor variations and quality deterioration of the product.

Abstract: Disclosed herein is a semiconductor device having a substrate, an insulating layer covering the substrate, a plurality of wiring layer formed on the insulating layer, each wiring layer having a top surface and a side surface, and a sidewall insulating film formed on and along the side surface of each of the wiring layers. The sidewall insulating film suppresses a hillock projecting from the side surface of each wiring layer.

Abstract: A microscope having an interchangable objective revolver holding a plurality of objectives and supported on a microscope body. The direction of the revolver can be changed by rotating a rotary member through 180.degree. so that a rotation plane surface of the revolver may be inclined downwardly toward the stand side or the operator side of the microscope selectively.

Abstract: A protective transistor against electric surge is fabricated on a silicon substrate together with a semiconductor integrated circuit implemented by a plurality of component field effect transistors, and the gate oxide film of the protective transistor is larger in thickness of those of the component field effect transistors of the semiconductor integrated circuit so that the protective transistor is hardly broken down even if the component field effect transistors are scaled down for increasing the integration density.

Abstract: A microscope placeable on a table comprises a bodytube for holding an optical system, a stage on which a specimen is placed, a stand for supporting the bodytube and the stage, a base supporting the stand and having a bottom surface which is placed upon the upper surface of the table, a focusing operation member rotatively operably provided on the stand for moving one of the bodytube and the stage along the optical axis, and a hand-placing portion protruded from a side of the base and provided near the focusing operation member and formed so that the lower end of the protruded portion may be spaced apart by at least a predetermined distance from a plane containing the bottom surface.
