A preform for metal matrix composite material comprising: inorganic particles, small-diameter inorganic fibers, and large-diameter inorganic fibers. An average particle diameter of the inorganic particles is 1 to 50 &mgr;m. An average fiber diameter of the small-diameter inorganic fibers is 2 to 5 &mgr;m, and an average fiber length of the small-diameter inorganic fibers is 10 to 200 &mgr;m. An average fiber diameter of the large-diameter inorganic fibers is 4 to 20 &mgr;m, and an average fiber length of the large-diameter inorganic fibers is 10 to 200 &mgr;m. The small-diameter inorganic fibers catch and disperse the inorganic particles in a process of forming a formed body, and the large-diameter inorganic fibers create voids in cooperation with the small-diameter inorganic fibers in the process of forming the formed body.

There are provided a heat insulating tool kit for piping, which can easily be attached to and detached from a piping in a limited space repeatedly and fixed in a stable form, can be attached so that a heating surface is in close contact with the outer peripheral surface of piping so that heat is conducted efficiently, which results in no overheating of heated portion, can be subjected to temperature control stably, and can be used in a clean room etc. because dust particles scarcely occur, and a heat insulating construction using the heat insulating tool kit. The heat insulating tool kit includes a piping; a band-shaped heat insulating unit which includes at least a heat insulating material and preferably a heating element and is wrapped with a heat-resistant resin film; a support cover consisting of a tubular element of a C-shaped cross section having a slit-shaped opening over the total length in the axial direction of the tubular element; and preferably an external cover of almost the same shape as that of the support cover. The heat insulating construction is formed as described below. The heat insulating unit is housed so that the non-heating surface of the heat insulating unit comes into contact with the tubular element inside wall of the support cover 14, and in a state in which ear portions at both ends of a heat insulating portion are pulled out of the slit-shaped opening, the butting portion at both ends of the heat insulating portion, that is, the slit-shaped opening of support cover is pressed on the piping, by which the piping is covered with the heat insulating portion and the support cover. Next, the opening portion of external cover in a widened state is pressed on the slit-shaped opening side of the support cover, by which the heat insulating unit and the support cover are collectively covered with the external cover 15.

Provided is a two-actor user authentication system with a reduced risk of leakage of authentication information.The two-factor user authentication system is designed to use, as a password, a one-time-password derivation rule to be applied to certain pattern elements included in a presentation pattern at specific positions so as to create a one-time password, and further use, as a second authentication factor, information identifying a client to be used by a user. An authentication server is operable to generate a pattern seed value adapted to uniquely specify a presentation pattern in combination with a client ID, and transmit the pattern seed value to an authentication-requesting client. The authentication-requesting client is operable to create a presentation pattern based on a client ID acquired therefrom, and display the presentation pattern to allow a user to enter thereinto a one-time password based on the presentation pattern.

In a gas combustion type fastener driving machine, a fuel gas and air are stirred by a fan within a combustion chamber, a stirred air-fuel gas mixture is burned by an ignition spark, and a striking piston is actuated by a combustion pressure to drive a fastening member. The machine is provided with a fan motor (320) for rotating the fan, and a control circuit board (100) for controlling an action of the fan motor (320). The control circuit board (100) detects an actuation signal for an igniter (310) that generates the ignition spark and controls a rotation speed of the fan motor (320) based on the actuation signal.
