Abstract: A method for producing polytetrafluoroethylene, which includes polymerizing tetrafluoroethylene in an aqueous medium in the presence of a nucleating agent and a hydrocarbon anionic surfactant to obtain polytetrafluoroethylene. A total amount of the nucleating agent and the hydrocarbon anionic surfactant at the initiation of polymerization is more than 50 ppm based on the aqueous medium.

Abstract: An object of the present invention is to provide a method for producing a saccharide polycondensate which is inexpensive and is applicable to a food or beverage product. Disclosed is a method for producing a saccharide polycondensate, which comprises carrying out a saccharide polycondensation reaction in the presence of activated carbon.

Abstract: A dynamometer device (1) is equipped at a tip end part of a dynamometer (3) with a cover (5) that covers the periphery of a torque meter (14). The cover (5) is formed on its side surface with an opening section (41) that is equipped with a door (42), and a rotation shaft is locked by inserting a locking plate (52) through this opening section (41). The locking plate (52) is slidably guided by a guide rail section. A part of an outer peripheral surface of the rotation shaft is provided with a surface to be locked that is along the tangential direction, and the rotation shaft is locked by engaging the locking surface (64) of the locking plate (52).

Abstract: A heat insulation plate (25) is interposed between a coupling (21) and an adapter flange (22) in a main shaft (6) of a dynamometer (3). A torque meter (24) is disposed between a coupling flange (23) that serves as a test-piece connection surface (56) and the adapter flange (22). To surround a periphery of these, a cover (7) is provided. An air conditioner utilizing a refrigeration cycle supplies a cold wind to an inside space of the cover (7). The heat insulation plate (25) suppresses heat transmission from an electric motor of the dynamometer (3) to the torque meter (24). Therefore, the torque meter (24) is effectively cooled by the cold wind.

Abstract: OFDM (orthogonal frequency division multiplex)-modulated wave output unit. An amplitude extraction section (108) extracts amplitude of an OFDM-modulated wave. A power-amplifier control section (114) sets the power supply of a power amplifier (113) to exceed the rated power when the extracted amplitude exceeds a specific amplitude, to expand the saturation point of the power amplifier. A compensation-value-selection control section (116) compensates the nonlinear characteristic of the power amplifier, when the power-amplifier control section expands the saturation point of the power amplifier.

Abstract: When an access-desired data base is set up in a private network, a public network, a contract provider for connecting the public network and the private network concerned, the private network in which the data base is set up, and a user terminal having an IP capsule encryption function for accessing the public network are used. The user terminal 10 connects to the contract provider 300 through the public network 200 at a visiting place, and achieves an IP address from the contract provider. The contract provider 300 accesses the private network 100 on the basis of the terminal request concerned, and the private network 100 authenticates an access of the terminal 10 concerned. The terminal 10 encrypts the communications, and carry out IP encapsulated communications through the public network 200 and the contract provider 300.

Abstract: An installation system for a cellular terminal separation type satellite communication portable terminal which includes a ground cellular terminal (11) capable of stand-alone communication, and a satellite communication portable terminal (12) that accommodates a ground cellular terminal, is electrically connected with the ground cellular terminal via a specified connector, and can communicate with a satellite under the control of the ground cellular terminal, includes a fixing-unit (25) that is fixed to a location least affected by radio wave transmission troubles and has a separated satellite communication portable terminal installed therein, and with connection units (14, 14b, 24a, 24b, 28) for permitting communications via a satellite by extending the span of the specified connector to electrically connect the separated satellite communication portable terminal with the separated ground cellular terminal.
