Abstract: A seat connection structure includes a reinforcing member and a rear seat. The reinforcing member reinforces a rear floor panel and left and right rear wheel houses. The rear seat is disposed in front of a vehicle body of the reinforcing member, and is connected to the reinforcing member via left and right fixing members. The left and right fixing members connect the seat back of the rear seat and the reinforcing member, and are connected to face a front surface portion of the reinforcing member formed on a front side of the vehicle body and facing a vehicle width direction.

Abstract: A network system with integrated security protection facilities. The system involves a transmission unit and a reception unit, which are coupled to each other via a network. In the transmission unit, a data management unit performs centralized management of source data that is stored in a plurality of storage units in a distributed manner. In response to a data transmission request from a terminal local to the transmission unit, a data collection unit collects requested data items from the data management unit. A security processor applies appropriate security protection processes to the collected data, depending on its data confidentiality level. An identification data attaching unit attaches identification data to the transmission data. This identification data informs the recipient of what sequence of security process primitives has been applied to the source data. A transmitter sends out the security-protected data over the network.

Abstract: A high-speed breaking switch of the seesaw type having an up-and-down contact plate balanced at the middle by the support of the switch body, a push member slidably attached to the up-and-down contact plate to push the up-and-down plate against the support all the time and at least one terminal formed on the switch body to permit one end of the up-and-down contact plate to abut thereon. The up-and-down contact plate has a raised fulcrum vertically at a level which is higher than the level at which the push member abuts on the up-and-down contact plate. The raised fulcrum is formed by a pair of raised fulcrum archs, one on each side of the contact plate. The up-and-down contact plate has a ramp-and-step plateau or inverted "V"-shaped projection formed thereon.

Abstract: An exhaust gas purification system for use in an internal combustion engine equipped with a dual exhaust system. The exhaust gas purification system includes a secondary air supplying port of a secondary air supplying passage opened into a selected exhaust pipe belonging to one of first and second exhaust pipe groups, while an exhaust gas deriving port of an exhaust gas recycling passage for recycling the exhaust gases to a downstream of the carburetor throttle valve is provided in another exhaust pipe belonging to the other of the first and second exhaust pipe groups for effective suppression of NO.sub.x through accurate control of the amount of exhaust gases to be recycled.
