The fail-safe mechanism of the system is composed such that a guard rail 31 having a flange 34 extending horizontally at the upper part of each of its vertical guide surfaces for guiding guard wheels 22, 23 provided to the vehicle is laid down on a guide track 3 (depression 10) along the center lone thereof, the vehicle is provided with automatic steering mechanisms 09 and actuators 06 for steering front and rear traveling wheels, and said guard wheels are provided to the vehicle rotatable in a lateral plane and received in the groove of the guard rail 31. A subsidiary guard wheel 33, which is smaller in diameter than that of the guard wheel 22(23), is provided thereon to be rotatable together with the guard wheel 22(23).

Abstract: The present invention provides the structure of a bogie for a vehicle in a track type transportation system in which the vehicle runs along a predetermined track, which can be simplified, and lightweight and which can be run at a high speed with the maintainability therefor being enhanced, comprising a guide rail 14 laid on the track 12, guide wheels 51 capable of traveling being made into contact with the guide rail 14, a guide arm 48 attached thereto with the guide wheels 51, and a guide wheel support bracket 52 for supporting the guide arm 48 arranged underneath an axle 22 of the vehicle so that the guide arm 48 is pivotable around a pivotal vertical support shat 56, left and right of the vehicle, and the guide arm 48, the guide wheels 51 and the guide wheel support bracket 52 constitute a unit structure which is attached to the axle 22 or a bogie frame 26 of the vehicle.

Abstract: The essential feature of the present invention is the provision of a track transportation system in which a vehicle runs on a predetermined track, being automatically steered, having a simplified and lightweight structure so as to surely ensure a safety, and to be capable of carrying out efficient and high-speed operation. The track transportation system according to the present invention incorporates a steering mechanism for automatic steering by means of an M actuator, a protection guide rail laid on the track, protection guide wheels which travel together with the vehicle along the protection guide rail without making contact with the latter, and a control means for controlling automatic steering in accordance with a result of determination by a track data determining means for determining a straight portion, a curved portion, a turnout portion or the like of the track in view of vehicle position data, and steering caused by the protection wheels making contact with the protection guide rail.

Abstract: Occurrence of overcharging and over discharging of batteries mounted on vehicles that travel on predetermined tracks in a wireless transit system is prevented by estimating SOC of the batteries with accuracy.

Abstract: Provided is a railway type feeder-lineless traffic system in which the weight of a vehicle is reduced while the structure of the vehicle is simplified, and it is possible to carry out a quick charge during a brief stopping time at a station or the like.

Abstract: A noncontact type power feeder system for feeding a power to a mobile object, in which a power feeding portion and a power receiving portion can be easily manufactured at low costs and which can transmit a high power.

Abstract: A tramway transit system for allowing a vehicle to travel along a track while automatically steered is proposed, in which the vehicle is provided with guard wheels and the track is provided with a protection track, and simplification in construction and weight saving of the automatic steering mechanism provided to the vehicle and space saving for the installation of the mechanism, can be attained. The vehicle (12) is provided with a steering mechanism (26) for steering the front and rear wheels (20, 22) by means of electrically driven oil hydraulic actuators 36, the protection track (14) is laid down on the road surface (15) of the track (01), the vehicle (12) is provided with guard wheels (40), and the interlocking mechanism (48) for connecting the guard wheels to the right or left wheels, the actuator (36) comprising the hydraulic cylinder (60), the two-way discharge pump (76), the variable speed, reversible rotation motor (78), and the closed circuit (82) provided with relief valves (86).

Abstract: An ultrasonic probe for performing a scanning of an ultrasonic wave by a reflection mirror is disclosed.

Abstract: An endoscope apparatus according to the present invention includes a warping velocity control device which receives an angle of warp detected by an angle detection device and a value of an electric current realized at this angle of warp and detected by an electric current detection device. The control device makes comparisons between the angle of warp and the value of the electric current and data about a normal state stored in a storage device. If the result is larger than data for the normal state by a predetermined value, the warping velocity is lowered while a discrimination is made that an abnormal state (the warp-enabled portion has come in contact with the body wall) takes place. Additionally, the apparatus could include a time detecting device for detecting a time in which an electric quantity supplied to a drive means is larger than a predetermined time. The warping velocity control device controls the warping velocity according to the comparison made by the time detecting device.
