Abstract: An optimization system includes an optimization server and a management server, and the management server controls an AGV. The AGV transports a cargo and notifies the management server of a traveling state during traveling. The management server stores the traveling state of the AGV in a database. The optimization server estimates the traveling parameter to be used for the subsequent experimental traveling and repeats an experiment based on an experiment design for experimental traveling and the number of times of back-and-forth sway and the right-and-left sway width of the AGV when the AGV travels by using the traveling parameter estimated from the default value of the traveling parameter and an experiment result of the experimental traveling of the AGV. After the experiment ends, the optimization server optimizes the traveling parameter for each traveling state of the AGV based on the experiment result.

Abstract: An automatic vehicle dispatching system is applied to a factory where manufacturing operation devices reside, and includes an optimization server, a management server, and AGVs. The management server controls transfer of the AGVs and transmits a current transport request received from one of the manufacturing operation devices to the optimization server. The optimization server predicts a future transport request to be issued by each of other manufacturing operation devices using predicted transport request interval patterns, and generates allocation models by allocating AGVs to each transport request in different patterns. The optimization server predicts required transfer times for the allocated AGVs and adds up the required transfer times for each allocation model.

Abstract: An automatic traveling system includes a management server and an AGV, and the management server controls the AGV. When there is a transport request, the management server determines an available AGV, determines a traveling route from a standby position to a loading position, determines a traveling parameter table corresponding to the traveling route, and transmits a traveling instruction including the traveling route and the traveling parameter table to the target AGV. The AGV travels along the traveling route by using a traveling parameter corresponding to the load of a cargo and the traveling velocity. The AGV also travels from the loading position to a transport destination and then from the transport destination to the standby position. For each traveling route, the traveling route and the corresponding traveling parameter table are transmitted to the target AGV.

Abstract: A coupling device that couples with a cart includes a coupling portion that couples with the cart, a base portion that guides the coupling portion, and a driving motor that drives the coupling portion. The driving motor drives and controls the coupling portion so as to be changeable among a first state in which the coupling portion is housed, a second state in which the coupling portion is capable of coupling with the cart, and a third state in which the coupling portion couples with the cart. With the coupling portion and a side frame of the cart facing each other, the coupling portion changes from the second state to the third state, thereby causing the coupling portion and the side frame to be coupled to each other.

Abstract: Follower pins 12 of a female housing 10 are fitted into cam grooves 35 of a lever 30 supported by axles on a male housing 20. These two housings 10 and 20 can be fitted together or separated by means of pivoting the lever 30 between a starting position, and an ending position. An upper supporting member 40 is formed at a right side of a hood 23, and a lower supporting member 44. When the lever 30 is pivoted to the starting position or the ending position, a tip thereof is supported by the supporting member 40 or 44, respectively, thereby protecting this tip from contact with other components, etc. The supporting members 40 and 44 protrude into dead space relative to the position of the housing 20. Consequently, no extra space is required when the housing 20 is placed in position, yet the lever 30 has increased length and angle of travel.

Abstract: A waterproof connector is provided with a moving support plate without requiring an increase in size of the connector. A moving plate (40) has a shape whereby a side wall (42) protrudes upwards from circumference edges of a base plate (41) having maintaining holes (44) adapted to receive tabs (24) of male terminal fittings. This moving plate (40) can be inserted in a movable manner within a hood (22) of male housing (20). A first sealing ring (51), for sealing the space between the moving plate (40) and an outer circumference face of the female housing (10), is formed on an attachment base of an inner circumference face of an anterior end (42A) of the side wall (42). A second sealing ring (52), for sealing the space between the moving plate (40) and in inner circumference face of the posterior end (42B) of the side wall (42). These sealing rings (51) and (52) are formed in a unified manner, by means of two-component molding, on the moving plate (40).

Abstract: Retainers 18 provided on an electrical connector housing 10 become approximately level with an outer wall of the connector housing 10 when terminal fittings 20 are inserted and, moreover, are maintained in a second stopping position whereby these retainers 18 are engaged with the terminal fittings 20. Outer faces of the terminal fittings 20 interfere with the retainers 18 as these terminal fittings are inserted, thereby causing the retainers 18 to bend resiliently and move to a position whereby they protrude form the outer wall of the connector housing 10. Then, after the terminal fittings 20 have reached a correct inserted position, the retainers 18 return resiliently to their second stopping position, engage with the terminal fittings 20, and prevent these terminal fittings 20 from being removed. At the point when the terminal fittings 20 are about to be inserted, the retainers 18 remain in a state whereby they do not protrude from the outer face of the connector housing 10.

Abstract: A waterproofed connector is provided with a moving support plate without requiring an increase in size of the connector. A moving plate 40 has a shape whereby a side wall 42 protrudes upwards from circumference edges of a base plate 41 having maintaining holes 44 adapted to receive tabs 24 of male terminal fittings. This moving plate 40 can be inserted in a movable manner within a hood 22 of a male housing 20. A first sealing ring 51, for sealing the space between the moving plate 40 and an outer circumference face of the female housing 10, is formed on an attachment base of an inner circumference face of an anterior end 42A of the side wall 42. A second sealing ring 52, for sealing the space between the moving plate 40 and an inner circumference face of the hood 22 of the male housing 20, is formed on an outer circumference face of the posterior end 42B of the side wall 42.

Abstract: A lever type connector is provided with a lever that has a rotatable or pivotable range wider than its rotatable or pivotable range during the connection of male and female housings without changing a moving stroke of a moving plate. The lever 20 is enabled to rotate from a connection start position to a connection end position located opposite from a standby position, and each cam groove 24 is formed with a play area 24C for preventing the lever 20 from being interfered with by cam pins 32 of a moving plate 30 when the lever 20 is rotated or pivoted toward the standby position. Since the cam grooves 24 of the lever 20 and the cam pins 32 of the moving plate 30 do not interfere with each other while the lever 20 is rotated or pivoted from the connection start position to the standby position, the moving plate 30 will not move together with the lever 20.

Abstract: A miniaturized lever is provided for an electrical lever type connector having a moving plate to support protruding terminals. Recesses are provided on cam pins of a moving plate and these fit together with cam pins of a female connector housing. As a result, the cam pins of the moving plate and female connector housing are unified, and in this unified state are then fitted in a cam groove of a lever. Consequently only a single cam groove is required, compared to the prior art where two cam grooves corresponding to the two cam pins are necessary.

Abstract: A lever-type electrical connector has a moving support plate 15 to prevent bending of protruding male terminals of a male connector housing 11. The support plate 15 has external flanges 20,42 to prevent inward movement of cam pins 18,41 due to the application of external force to the base of the support plate 15.The plate 15 may have a continuous upstanding wall 17 to further resist distortion due to external force.

Abstract: A connector is provided in order to enhance a tactile sensation by providing a restoring force to a lock piece and further to attain an original locking function at the fitting of both a male and female connector housing. A dome covering the upper edge of a lock piece is formed on a female housing, and an arm which protrudes rearwardly and which can be elastically deformed is affixed to the dome. A projecting contact part protrudes downwardly at the end of the arm and closely contacts the upper edge of the lock piece. When the male and female housings are interfitted, a gaff part on the lock piece engages a protrusion on the male housing and swings upwardly, and in accordance with it, elastically deforms the arm by pushing the projecting contact part. When the male and female housings are normally interfitted, the lock piece restores to its original position and is locked by engagement of the gaff part with the backside of the protrusion.
