    摘要： The present invention relates to a Personal Rapid Transit system for transporting passengers along a pre-set guideway, and more particularly relates to a future Personal Rapid Transit vehicle braking system. A conventional braking system can not provide the large braking force required for very short headway operation under the effect of weather and environmental conditions due to variations in the available coefficients of friction at the running surfaces. In particular, the Personal Rapid Transit which is a public transportation system can not adopt the conventional braking system since the vehicles are powered by linear motors and are independent of traction. The PRT brake system comprises brake reaction rails (120) mounted on each inside of the guideway and brakes (300) acting on these brake reaction rails (120) as calipers. The brakes are automatically actuated when electric power supply is cut off, and thus can serve as parking brakes and emergency brakes. Since the braking system of the present invention is supplied with power via the strain energy stored in steel spring members, no external power source for its operation is required. Furthermore, the system comprises a redundant failure monitored brake releasing unit (380) which is driven by duplicate redundant electric motors. Accordingly, the PRT braking system of the present invention represents a highly efficient fail-safe parking or emergency brake.

    摘要： A semiconductor device comprises a semiconductor substrate having a high voltage region and a low voltage region, at least a pair of adjacent high voltage MOS transistors disposed on the high voltage region of the semiconductor substrate, and low voltage MOS transistors disposed on the low voltage region of the semiconductor substrate. A first element isolator comprises a first shallow trench disposed on a surface of the low voltage, region of the semiconductor substrate, and a first dielectric embedded in the first shallow trench. A pair of second element isolators comprises two second shallow trenches spaced apart at an interval between a source region or a drain region of the pair of the adjacent high voltage MOS transistors and a source or a drain region of the other of the pair of the adjacent high voltage MOS transistors, and a second dielectric embedded in each of the second shallow trenches. The second shallow trenches are disposed on a surface of the high voltage region of the semiconductor substrate. A channel cut region having a high impurity concentration is disposed on the surface of the substrate between the second shallow trenches.

    摘要： A position recognition apparatus for personal rapid transit. The personal rapid transit system comprises a chassis (40) for moving at the inside of a guideway (10) and a chamber for passengers being mounted on the chassis (40) at the outside of the guideway (10). The chassis (40) is provided with guidance wheels (41 and 42), electric linear motors (44a and 44b), a switching device, brakes, a control apparatus (70) and electric power supply devices. Bar code scanners (60a and 60b) are installed at both sides of the chassis (40) in the inside of the guideway (10). Bar codes include figures and letters indicating sections and positions at a certain interval on the guideway (10), and are printed on bar code members (50a and 50b) having a predetermined width which is made of plastics. The plastic bar code members (50a and 50b) on which the same bar codes are printed are attached to both sides of the guideway (10). The scanners (60a and 60b) recognize positions and speed of the vehicles (80) from bar codes which are arranged opposite to the scanners (60a and 60b) fixed at the chassis (40) of the vehicles (80), and transmit the data to a computer which is installed adjacent to the scanners (60a and 60b) for controlling the vehicles (80). The computer controls the driving motors of the vehicles (80) to thereby provide effects of performing accurate interval maintenance and preventing in advance rear-end collision and collision between vehicles under the control of interval and speed.
