Title: Segment
Inventor: SHISEKI AKIO
IPC: E21D9/06
Filed: 1993-03-12
Abstract: PURPOSE:To provide a steel sheet pile between shield tunnels to facilitate work by providing a slide groove for sliding a steel sheet pile in an axial direction of a tunnel on a steel sheet pile mount member and inserting the steel sheet pile into the groove. CONSTITUTION:Segments 1, wherein a slide groove for sliding a steel sheet pile is formed on a steel sheet pile mount member, are applied continuously only onto the opposed surfaces of a tunnel in a long side direction thereof, while ordinary segments are applied onto the remainder of the surface of the tunnel. Next, after shield tunnels are constructed, a steel sheet pile is inserted into a slide groove 2c of a corner steel sheet pile mount member 2 from the side of a shaft. At that time, the steel sheet pile is slid, while a cover 3 is being broken by pushing forces of the steel sheet pipe, so that the pile is disposed between the shield tunnels, following which the ground is excavated from the side of one of the vertical shaft toward the other shaft and the soil of the ground is improved, if necessary, to seal water, thereby ensuring safety of construction. And the steel sheet piles are connected by means of steel plate hinges and both ends are inserted into the slide groove 2c of the member 2 to form a three- hinge construction. As a result, the shield tunnels are offset vertically and horizontally, so that they can be easily adjusted even during the construction.

Title: Fuel tank and method of limiting leakage of fuel
Inventor: BURAIAN FUIRITSUPU CHIN
IPC: B60K15/00
Filed: 1983-03-28
Abstract: A liquid fuel tank for a vehicle is provided with a fuel outlet duct in a circuit about the base of the tank and fuel outlet duct vents connected to the outlet duct and extending above the highest part of the tank. During normal operation of the tank, a non-return air vent allows the flow of fuel from the outlet duct. In the event of an accident, or some other occurrence which results in the tank being tilted, further fuel flow from the outlet duct is cut off by air drawn into the fuel outlet duct from the outlet duct vents. The angle through which the tank must be tilted to allow air from the outlet duct vents to be drawn into the outlet duct may be predetermined by the extent of the circuit about the base of the tank of the outlet duct. Such a non-spill fuel tank, which is self contained in operation, is suitable for use in on-road and off-road wheeled and tracked vehicles, hovercraft, and aircraft which are in danger of being blown over when on the ground.

Title: Gate firing control system of thyristor converter
Inventor: HORIKIRI JIYUNICHI
IPC: H02M1/084
Filed: 1984-03-19
Abstract: PURPOSE:To perform a rapid response to a current by leading the control delay angle this time by the prescribed angle when the difference of the control delay angles between this time and previous time is larger than the prescribed angle, and then leading the remaining angle without calculation. CONSTITUTION:Firing signals to thyristors 1-6 are output from gate firing output circuit 8, the voltage and current of controlled amount are input through an A/D converter 7 to a microprocessor 9, the control delay angle is calculated by the signal and a current command from a current command generator 10 to decide the gate firing timing this time. In this case, if the control delay angle this time is led more than the angle (60 deg.-theta0) or larger than the delay angle of this time, the control delay angle this time is led by the certain decided angle, and the remaining leading angle is led after next time without calculating the control delay angle.

Title: Snow tire consisting of inner and outer tires
Inventor: KATAJIMA HISAKATSU
IPC: B60C17/01
Filed: 1985-03-16
Abstract: PURPOSE:To enable the contact area with ground to be increased preventing a tire effectively from slipping by combining two tires in such a way that the tire pressure in an inner tire is kept ordinary, but the tire pressure in an outer tire is set to be lower than that of the inner tire. CONSTITUTION:This tire is composed of an inner tire and an outer tire. And the tire pressure in the outer tire is set to be lower that of the inner tire so that the inner surface 2B of the outer tire B comes in contact with the outer surface 1A of the inner tire A at the section where the tire is in touch with ground. Thus, the configuration where the inner surface 2B of the outer tire touches the outer surface 1A of the inner tire, enable contact area of the tire to be increased allowing frictional coefficient at the contact surface to be increased. This prevents the tire from slipping on a road which is compressedly covered with snow enabling the braking effect to be augmented when a car stops.
