A steam engine in which a liquid and a steam are jetted so that a rotor is turned by the reaction thereof, and the rotor having a well-balanced simple structure. In the steam engine, the rotor 5 having a plurality of bent flow paths 53A to 53D arranged at regular intervals therein is rotatably supported in a closed container 1 filled with the liquid being fitted onto a boss portion 11 of the closed container 1. The boss portion 11 is alternately forming slide-contact portions 11A having a steam feed port and recessed portions 11B. The steam fed into the bent flow path 53 from the steam feed port causes the liquid in the flow path to be jetted outward to rotate the rotor 5. The rotor 5 is of a point-symmetrical shape in cross section free of unbalanced weight, has no moving part, and is simple in structure. When the bent flow path 53 communicates with the recessed portion 11B, the steam remaining in the flow path is cooled and disappears, and the flow path is filled with the liquid.

An information processing system, information communication terminal and method, information processing apparatus and method, recording medium, and program capable of enabling safer electronic commercial transactions. A point-of-purchase server generates purchasing information using a card Identification number allotted to a non-contact IC-card of a mobile telephone. A point-of-receipt server acquires this purchasing information and confirms the card identification number allotted to the non-contact IC card of the mobile telephone and a purchasing card identification number. The authentication server calculates user trustworthiness and store trustworthiness based on temporary commercial transaction information stored in the non-contact IC card of the mobile telephone. The calculated user trustworthiness and store trustworthiness is then reference by the mobile telephone and point-of-purchase server in the next commercial transaction.

An insertion apparatus includes: a tubular member equipped with a propulsion power generating portion; a rotating portion for rotating the tubular member provided with the propulsion power generating portion around the longitudinal axis of the tubular member; and a distal portion which is provided on a more distal side than the tubular member rotated by the rotating portion, is slidably provided to the tubular member, and is disposed with an observation portion for observing a body to be examined.
摘要:
A steam engine of a simple constitution capable of efficiently obtaining mechanical energy not only from a heat source of a high temperature but also from various heat sources in a low-temperature state such as the exhaust heat of an internal combustion engine. The engine comprises a displacement engine 1 having a rotor 13 that rotates, a steam-generating portion 2 arranged thereunder and a condenser 3 arranged thereover. Water heated in the steam-generating portion 2 becomes the steam which is fed into the displacement engine 1, enters into an operation chamber that moves up, rotates the rotor 13 and is, thereafter, fed into the condenser 3 where it is condensed to turn into the condensate. The condensate falls on the rotor 13 on the lower side due to gravity, and is refluxed into the steam-generating portion 2 through the operation chamber that moves downward with rotation of the rotor 13. The steam engine efficiently operates even at low speeds, requires no pump for refluxing the condensate, and is constituted in a compact size.

The present invention provides an illumination device capable of improving an efficiency of acquiring light emitted by light emitting diodes, which are provided in a light source module and used as a light source, and capable of achieving a uniform luminance distribution, and provides a liquid crystal display device using the illumination device. The illumination device includes a circuit board, red, green and blue light emitting diodes, and a lens body. Each red, green and blue light emitting diode is mounted on the circuit board and connected with a wiring pattern formed on the circuit board. The lens covers the red, green and blue light emitting diodes, and includes first portions each having two first side surfaces and second portions each having two second side surfaces. The first and second portions are alternately arranged. A distance between the first side surfaces is larger than a distance between the second side surfaces. The three red, green and blue light emitting diodes are provided in each first portion of the lens.
