A solar heat collector comprises an evacuated transparent pipe; a solar heat collection plate disposed in the transparent pipe; a heat pipe, disposed in the transparent pipe so as to contact with the solar heat collection plate, and containing an evaporable working liquid therein; a heat medium pipe containing a heat medium to be heated; a heat releasing member extending along the axis of the heat medium pipe and having thin fin portions extending from the axis to the inner surface of the heat medium pipe; and a cylindrical casing surrounding coaxially the heat medium pipe to provide an annular space which communicates with the heat pipe. The evaporable working liquid evaporates, receiving solar heat collected by the heat collection plate. The resultant vapor heats the heat medium through the heat medium pipe and the heat releasing member.

To extract part of a large volume of traffic and adjust the total volume of traffic dynamically. When a communication request is originated from a telecommunications apparatus, a communications control unit makes an inquiry to a service control unit. The service control unit screens originators based on originators' attribute information in its possession and service contract information. Then, based on the results of screening, it sends back to the communications control unit instructions to reroute subsequent calls. The communications control unit connects to the information processing unit based on the reply from the service control unit and transfers information. Thus, only the communication requests which satisfy predetermined criteria are connected. The information processing unit compiles statistics on the transferred information based on attribute information in its possession. The statistics are transferred to the information providing unit and to the information processing unit.

The invention provides a laser oscillator including (a) laser medium having a characteristic that distortion is caused in the laser medium by applying electric field thereto, (b) an optical pumping source for exciting the laser medium to thereby generate laser beam, (c) a pair of terminals through which a voltage is applied to the laser medium, and (d) an optical resonator including a total reflection coating attached to one of end surfaces of the laser medium and a partial reflection coating attached to the other of end surfaces of the laser medium. The laser oscillator provides advantages as follows: (a) laser outputs can be stabilized; (b) a laser oscillator can be small-sized; and (c) a laser apparatus can be also small-sized by incorporating the small-sized laser oscillator thereinto.

The present invention provides an electrode catalyst layer comprising catalyst particles, an ion exchange resin and a water repellent agent. The water repellent agent contains (A) a fluorine-containing copolymer having a structure unit derived from a polyfluoroalkyl-containing (meth)acrylate and/or (B) a fluorine-containing copolymer having a structural unit represented by derived from a fluorine-containing olefin monomer and a structure unit represented derived from a vinyl ether monomer. The electrode catalyst layer contains 0.1 to 20% by weight of the water repellant agent. The electrode catalyst layer exhibits excellent balance between water retention and drainage in an electrode, good power generation performance under any of low humidity and high humidity conditions, and also excellent durability in power generation.

A composition for recovery from or prevention of central nervous system fatigue (brain fatigue), comprising as active ingredients at least any amino acid selected from the group consisting of tyrosine, methionine, phenylalanine and glutamine, especially methionine and phenylalanine together with a branched chain amino acid of L-valine, L-leucine or L-isoleucine. This composition is provided as an injection agent or fluid infusion, or as, through addition of an appropriate vehicle such as starch or lactose, a solid dosable form (pharmaceutical application) such as tablets, granules or powder, or as any of various drinking water forms (food application) such as those known as health drink.

A case 6 is intermittently conveyed on a box transfer conveyor 8, and contains vessels 4 disposed in an array of four vessels in a longitudinal row and three vessels in a transverse row. A magazine introduction conveyor 18 is disposed to extend in a direction orthogonal to the conveyor 8, and a robot 24 is disposed adjacent to a crossing between the both conveyors. The robot has four grips 36 mounted thereon, each having suckers 66 and a retaining plate 68 which maintains a leaflet 12 declined downward. The leaflet includes a fixture 12b with an opening 12a therein and a display piece 12c which extends from the fixture. The grips hold attracted a leaflet around the opening in the fixture to remove it from a magazine 16. After the grips are driven into the case to bring the leaflet into abutment against a partition 10, the grips are moved to terminate the abutment, whereupon the lower portion of the leaflet drops into the space defined by the partition, and the grips are centered with respect to the vessel to fit the leaflet around the vessel. In this manner, a fitting of the leaflet around the vessel contained in the case is enabled by using the robot 24, and thus can be automated without requiring a manual intervention.
