  • Patent number: 10340532
    Abstract: A separator for fuel cell includes a corrugated portion formed to have a corrugated cross section where a first groove that is concave to a first surface to form a flow path for a first fluid on the first surface and a second groove that is concave to a second surface opposite to the first surface to form a flow path for a second fluid on the second surface are arranged alternately and repeatedly. Each of the second grooves has at least one shallower groove section formed to have a less depth from the second surface than depth of a remaining groove section and provided to form a communication flow channel on the first surface side, which is arranged to communicate between two flow path spaces for the first fluid that are adjacent to each other across the shallower groove section.

  • Patent number: 9315453
    Abstract: [Problem] For example, 4-(3-benzyloxyphenylthio)-2-chloro-1-(3-nitropropyl)benzene (compound 1) is used as an intermediate for producing a 2-amino-2-[2-[4-(3-benzyloxyphenylthio)-2-chlorophenyl]ethyl]-1,3-propanediol hydrochloride which has excellent immunosuppressive activity. This compound 1 is traditionally obtained only as an oil and thus handling and refining were difficult. [Solution] A crystal of the compound 1 is obtained. A method of crystallizing the same is also established. Furthermore, a simple refining method is also found which comprises stirring in suspension the crystal in a solvent. Since the compound 1 can be obtained as a crystal, it is easier to handle and long term storage is possible.

  • Patent number: 7164932
    Abstract: A millimeter band transmitter transmits one or more indirect path signal waves from the main lobe of a transmit antenna, and a direct path signal wave is transmitted in a side lobe of the transmit antenna. A receiver simultaneously receives each of the indirect and direct path signal waves if the receive antenna is unobstructed. If the direct line of sight path between the transmitter and receiver is blocked, the receiver only receives one or more of the indirect path signal waves.

  • Publication number: 20050177854
    Abstract: In conventionally receiving satellite broadcasting (BS, CS) and terrestrial broadcasting (VHF, UHF) services, transmitting the services to a plurality of TV receivers in an individual house results in complicated wiring and a community house is also limited in the number of installed TV receivers due to previously setting a distributor and thus requires an additional distributor to be installed when a TV receiver is additionally installed. The milliwave receiving and transmitting system of the present invention allows a broadcast signal to be transmitted and received indoors via indoor, wireless milliwave transmission without using any indoor wiring.
