    • A tamper resistant apparatus 101 is mounted inside of a PC 900 and stores confidential information A through C. The tamper resistant apparatus 101 receives data from an application 118 which operates on the PC 900, processes the data using the confidential information A through C, and returns processed data to the application 118. To the tamper resistant apparatus 101, plural external sensors 110 provided to the PC 900 are connected. The plural external sensors 110 detect opening/closing of a case of the PC 900 or movement of the body of the PC 900 and send a detection signal to the tamper resistant apparatus 101. On inputting the detection signal from the plural external sensors 110, the tamper resistant apparatus 101 selects and erases confidential information to be erased from the confidential information A through C according to the tamper resistant policy stored previously.

    • Secret key backup is safely implemented even if a role base access structure in which the access structure is specified using roles is used. An all combination generating unit 107 obtains a backup participating user list 201 which is a list of backup participating users and a list of validated roles validated by the users, and a role base access structure 202 which is a combination of specified roles by which a secret key 205 can be restored, and generates an all combination extracted result which is all combinations of restoration enabling users of the secret key by applying users described in the backup participating user list 201 to the specified role. A same user/role deleting unit 108, etc. deletes a combination showing the same user redundantly, etc. from the all combination extracted result, a general access structure secret distributing unit 114 generates fragments of secret key from the secret key, and distributes the fragments of secret key to the combinations of users from which the redundancy is removed.

    • An anti-rolling structure for a double headed piston of a disc cam type reciprocative compressor, comprising a cylinder block (1) through which a plurality of pairs of front and rear cylinder bores (4) are provided in parallel to a drive shaft (3) rotatably secured in the center of the cylinder block (1), and a double headed piston (8) slidably inserted in the respective pair of cylinder bores (4) for reciprocation in the longitudinal direction. A disc cam (13) having opposite sinuous surfaces (13') and rotatably accommodated within a cam chamber (5) is fixedly secured to the drive shaft (3), and a pair of front and rear cam rollers (14F, 14R) are arranged between the disc cam (13) and the piston (8) in a slidable and rotatable manner so as to nip the disc cam (13) between both cam rollers (14F, 14R) to transmit the rotation of the disc cam (13) to the piston (8) as a reciprocation in the longitudinal direction thereof. The front and rear cam rollers (14F, 14R) are positioned so that the axes of rotation thereof are not included in the center plane defined by longitudinal axes of the piston (8) and the disc cam (13) but disposed, respectively, in the opposite areas sectioned by the center plane with a substantially equal deviation from each other from the center plane. According to the above structure, the rolling motion of the piston (8) can be effectively restricted throughout the operation of the compressor.

    • A rotary compressor for compressing fluid. A housing having a cylindrical internal cavity is provided with vanes and delivery ports. A rotor is rotatably mounted in the housing. The rotor has a portion for making a sealing contact with the inner peripheral surface of the housing. The rotor has a suction chamber formed therein. The number of the vanes is greater by 1 (one) than the number of the sealing contacts between the rotor and the inner peripheral surface of the housing. At least one suction port is formed through the wall of the rotor, so that the fluid in the suction chamber may be sucked into the working chamber defined by the vanes, rotor and the housing. The suction port is so located that, when a working chamber has been expanded to its maximum volume, the suction port is positioned between the vane located at the leading side of the working chamber as viewed in the direction or rotation of the rotor and the sealing portion closer to the vane. The fluid compressed in the working chamber is delivered to the outside of the housing through the delivery ports.
    • 一种用于压缩流体的旋转式压缩机。 具有圆柱形内腔的外壳设有叶片和输送口。 转子可旋转地安装在壳体中。 转子具有用于与壳体的内周面进行密封接触的部分。 转子具有形成在其中的吸入室。 叶片的数量比转子和壳体的内周面之间的密封接触的数量大1(1)。 通过转子的壁形成至少一个吸入口,使得吸入室中的流体可以被吸入由叶片,转子和壳体限定的工作室中。 吸入口的位置使得当工作室已经膨胀到其最大容积时,吸入口位于在转子的方向或旋转方向上观察到的位于工作室的前侧的叶片和密封件 更靠近叶片的部分。 在工作室中压缩的流体通过输送口输送到壳体的外部。
