Abstract: A connector assembly includes a first connector and a second connector. The second connector is engageable with the first connector along a downward direction in a state where the first connector is below the second connector. The second connector includes a second contact, a second holding member and an operating portion. The operating portion is held by the second holding member so that a positional relation therebetween is kept when a force is applied to the operating portion along an upward direction and when a force is applied to the operating portion along a first horizontal direction perpendicular to the upward direction or a second horizontal direction opposite to the first horizontal direction. The second connector is removable from the first connector when a force is applied to the operating portion either along the upward direction or along the first or second horizontal direction.

Abstract: On ad hoc networks in which connection relationships among communication terminals constantly change, the processing load increases when authentication is performed each time a connection relationship changes. According to this invention, when communication terminals possess the same common key, mutual authentication is conducted with that common key, and when communication terminals do not possess the same common key, mutual authentication is conducted with a public key. Communication terminals that conducted mutual authentication exchange and retain a common key that they selected and common keys received from other communication terminals. When neither communication terminal possesses a common key at authentication, one terminal creates a common key and distributes it to the other terminal, and when one terminal has a common key it creates that common key and distributes it to the other terminal.

Abstract: The present invention relates to a common key sharing method in an ad hoc network constituted by wireless communication terminals implemented with relay functions thereon, comprising a common key generating step in which a first wireless communication terminal responsible for relaying generates a common key, a common key distributing step in which the first wireless communication terminal responsible for relaying distributes the common key to a second wireless communication terminal within a wireless communication area, and a transferring step in which the second wireless communication terminal which received the common key holds the common key, and the second wireless communication terminal transfers the common key to a third wireless communication terminal within a wireless communication area, when the second wireless communication terminal is responsible for relaying. Accordingly, it is possible to share a common encryption key within the ad hoc network.

Abstract: An intake flow control apparatus for an internal combustion engine eases operation of an air flow regulator and permits use of a short intake passage, thus providing a high output. The intake flow control apparatus includes an air routing member having an intake passage formed therein, and an air flow regulator opposed to an upstream-side opening of the intake passage. The air flow regulator moves in an intake axis direction while being guided by a light-weight guide structure to control the amount of intake air supplied. The air flow regulator may include plural valve elements different in operation timing, in which a valve actuator successively actuates the plural valve elements in accordance with a throttle operation to control the amount of intake air. The apparatus also includes a vacuum moderating structure for reducing the effective strength of a vacuum applied to the air flow regulator.

The injector is supported on a head cover, and at least part of a compressed air supply passage for supplying compressed air to the injector is provided directly in the head cover. Further, an injector housing is formed integrally with a head cover which forms part of an engine body. With this configuration, the scale of the engine, the complication of the structure around the engine, and the number of part required can be kept to a minimum.

Abstract: An optical marking system is disclosed, in which a light beam of a preset wavelength is generated by a light source. An optical system receives the light beam generated by the light source and directs the received light beam in a present direction. A pattern generator includes a pattern forming section and a non-pattern forming section. Further, a control section controls the optical system to effect a first mode, in which the light beam is directed to the pattern forming section of the pattern generator, to form a predetermined pattern and a second mode, in which the light beam is directed to the non-pattern forming section of the pattern generator. The first and second modes are effected in a preset sequence.
