摘要:
A wavelength converter implements high speed, high efficiency, low noise wavelength conversion without performing high voltage poling of a crystal, and enables switching and modulation of converted light in response to an electric field. A KLTN crystal, includes a deposited-gold electrode within its incidence plane, and is connected to a DC power supply via a copper wire. The crystal material is composed of KTa1-xNbxO3 and/or K1-yLiyTa1-xNbxO3. A polarizer controls the polarization of the fundamental wave in the direction parallel to the electric field, and launches it into the electrode of the KLTN crystal. The KLTN crystal, rotating on an axis in the direction of the electric field, launches only part of the generated SHG light with the same polarization direction as that of the incident light into a photo multiplier tube through a polarizer.
摘要:
An optical waveguide capable of having various characteristics and a method of manufacture thereof as well as a method of manufacturing a crystal film are provided. An optical functional material KTaxNb1-xO3 is used as an optical waveguide. The input optical signal is transmitted to the KTaxNb1-xO3 film. The KTaxNb1-xO3 film undergoes changes in optical property when an external voltage signal is applied to the electrode. Therefore, as it passes through the KTaxNb1-xO3 film, the input optical signal is modulated by the characteristic change. The modulated optical signal is taken out as an output optical signal.

摘要:
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.
