摘要:
An engine intake system includes a primary port for introducing intake gas throughout an entire engine operating condition. A secondary port is provided with a gate valve which is opened in a high engine load condition for introducing the intake gas. A ratio of a tumble flow to a swirl flow is gradually increased as the gate valve is operated from an entirely closed condition to a fully open condition. According to this invention, ignition and combustion characteristics can be improved.

A combustion chamber for an engine is provided between a cylinder bore formed in a cylinder block, a generally conically-shaped wall formed in an under wall of a cylinder head, and a piston in the cylinder bore. The combustion chamber has a structure into which an intake port opens so as to introduce an intake air flow closer to a marginal portion than a central portion of the combustion chamber, thereby generating a swirl flow of intake air in the combustion chamber. The combustion chamber also includes a curved air flow guide wall formed in the generally conically-shaped wall which extends from near the intake port so as to approach the cylinder bore surface gradually, thereby generating what is termed a squish flow of intake air.

A monitoring system for preventing crime in a home, includes a plurality of terminals for monitoring whether predetermined monitoring points are in a stationary or nonstationary state. Further, the monitoring system includes a central processing device for controlling the setting/canceling of alarm operations of the terminals. The central processing device has a communication unit that receives stationary/nonstationary information from the terminals and transmits predetermined information including commands to the terminals. Each terminal has a communication unit that transmits stationary/nonstationary information to the central processing device and receives the predetermined information from the central processing device. Thus bidirectional communication can be achieved between the central processing device and the terminals. The terminals may include a terminal with an emergency call unit which, in an emergency, calls or notifies another, and a terminal having a notification unit which indicates that a nonstationary state has been accepted by a predetermined point of contact.

A movement pattern recognizing apparatus has a movement signal detection device including a sensor for detecting a mobile body in a detection region and for providing a movement signal indicating the position of the mobile body. The signal changes as time elapses. The apparatus further has a movement pattern storage device for storing data about previous movement patterns which were realized when a mobile body moved in the detection region, and a movement pattern selection device for selecting data about the movement pattern from the movement pattern storage device based upon the movement signal detected by the movement signal detection device.
