Abstract: The present invention provides a method for measuring nuclear magnetic resonance that employs a compound in which a plurality of nuclei is labeled with isotopes as a probe agent, highly selectively and highly sensitively obtains a nuclear magnetic resonance signal of the above described probe agent, and can attach a spatial positional information to the above described nuclear magnetic resonance signal, and an apparatus therefore.

Abstract: A polymer has a fluorescent dye sensitive to a hydrophobic environment. When a pH around the polymer decreases within a range of pH of equal to or greater than 5.5 and less than 7.4, and a secondary structure of the polymer changes from a random coil to a helix.

Abstract: There are provided a novel compound which captures a multisite phosphorylated peptide or protein specifically to a phosphorylation site and a method for detecting a multisite phosphorylated peptide or protein using the same. In particular, there are provided a compound which specifically detects an excessively phosphorylated tau protein observed in the brain affected by Alzheimer's disease and a method for diagnosing Alzheimer's disease in vitro or in vivo using the compound.

Abstract: The present invention relates to a method of introducing nucleic acids into cells by electroporation, comprising the step (A) of loading nucleic acids to the surface of an electrode; the step (B) of adhering cells on the obtained nucleic acid-loaded electrode surface; and the step (C) of applying electric pulses to the adhering cells. According to this method, not only efficient introduction of a gene into cells but also gene introduction at desirable timing and at desirable sites can be performed without damaging the adhering cells.

Abstract: An unmanned vehicle guide system has guide routes made of a magnetic material and an unmanned vehicle guided to travel on the guide route. The unmanned vehicle has an exciting coil for emitting a magnetic field, a pair of detection coils, arranged in a direction perpendicular to the travel direction of the unmanned vehicle, for detecting a magnetic field change, a comparator for measuring an output-difference between the detection coils, and a steering device for steering the unmanned vehicle such that the output-difference becomes a predetermined value. At an intersection where a plurality of guide routes intersect and in the vicinity thereof, at least one guide route lacks a magnetic material. Alternatively, an extra marker is added to each of the guide routes that intersect at the intersection.

Abstract: An unmanned vehicle guidance system has a guide lane pattern and sensors. The guide lane pattern is formed by placing or burying an object to be detected in a lattice manner on or in a floor surface. The sensors are loaded on an unmanned vehicle and detect the object to be detected.

Abstract: A vibration damping material having an improved mechanical strength and excellent vibration damping characteristic is disclosed.The material is made by usage of composition of 40 to 90 weight percent of iron oxide particles 0.1 to 100 .mu.m in size and 60 to 10 weight percent of resin.

Abstract: The noise level of an impact printer is reduced by at least 5 dB by providing a resonant absorption chamber between the printer frame and the cover which is designed so as to have a resonance frequency corresponding to the fundamental frequency of the printer noise.

Abstract: In an automatically swingable compact rear view mirror carried by a universal pivotal center support within a hood, a drive motor electrically connected to a given remote control equipment for the driver includes an output shaft which extends, on the side opposite to the end opening of said hood which said mirror faces, substantially parallel to the axial direction of a mechanism for moving a universal pivot coupled to the mirror for free swinging of the latter about the center support. Preferably a pair of universal pivots may be provided on the mirror defining a center angle of approximately 90.degree. with respect to the center support.
