Abstract: An underwater scooter includes a watertight vessel enclosing an engine disposed in the fore part of a cylindrically shaped main frame, a propeller disposed in the aft area, and a driveshaft passes through the interior of the main frame and transmits the output of the engine to the propeller. An operator rides upon air tanks disposed between the engine and the propeller on the main frame, so the burden on the operator can be reduced in comparison to that of conventional types that tow the operator. In addition, the propeller is disposed aft of the operator and also the exhaust gas from the engine is exhausted aft of the operator, so there is no risk of either the jet of water ejected by the propeller or the exhaust gas reducing the field of view or causing articles (goggles, etc.) worn by the operator to come off.

Abstract: An underwater scooter is provided with an engine enclosed in a watertight vessel and an electric motor enclosed in the watertight vessel and connected to the output shaft of the engine, and a propeller disposed upon a main frame and connected to the output shaft of the motor to be driven and turned by at least one of the engine and the motor so as to propel the scooter. In other words, the scooter is a hybrid type having the engine and electric motor as the drive power of the propeller. With this, the operator can easily re-start, once stopped on the surface of the water or underwater. Moreover, since the propeller can be driven even by the engine, a distance of travel is elongated with less increased weight, when compared to the case that the propeller is driven solely by the engine.

Abstract: An underwater scooter including a main frame on which are disposed two air tanks serving as a saddle area for the operator, a depth adjusting mechanism disposed to the fore of the air tanks, and a steering mechanism disposed to the aft of the air tanks. The depth adjusting mechanism can be swiveled freely around a vertical axis using a swivel mechanism, and moreover the angular displacement in this swiveling is transmitted by a swivel angle displacement transmission mechanism to the steering mechanism so that a rudder swivels around a vertical axis, and thus while the underwater scooter is traveling, the operator can ride upon the main frame and also adjust the depth of travel and direction of forward motion of the underwater scooter by manipulating the depth adjusting mechanism and steering mechanisms. Thus, the burden on the operator is reduced in comparison to that of the conventional types of scooters that tow the operator.

Abstract: In a method for analyzing a biomolecule by localizing the biomolecule on a solid phase and detecting the biomolecule as a visible two-dimensional signal, the signal is detected by capturing a two-dimensional image on the solid phase with use of a scanner comprising a light source for irradiating a light on the solid phase and an image sensor for receiving a reflected light from the solid phase and capturing the two-dimensional image on the solid phase by two-dimensionally scanning the solid phase, and analyzing obtained two-dimensional image data.

Abstract: This invention provides a color matching apparatus for automotive repair paints with which the color matching of a repair paint to an existing paint, whether containing or not containing a metallic or pearlescent pigment, can be performed with high precision in a reduced number of steps even by the novice. The apparatus of the invention comprises a computer, a color data file and a database reference system.

Abstract: A method of determining the formulating ratio of metallic or pearlescent pigments to colorants for matching the color of a metallic or pearlescent coating to an target color wherein, the spectral reflectances of a plurality of samples varied in the formulation of colorants and metallic or pearlescent pigments are measured with a goniospectrophotometer and stored in a computer memory beforehand and, in performing a CCM using the stored data, reproduction spectral reflectances are calculated by reflecting the changes in spectral reflectance due to changes in the amount of the metallic or pearlescent pigments.
