In a driving unit for an electric motor driven bicycle, a motor (31) has an output shaft coaxial with a crank shaft (39) of a pedal. A planet roller reducer (40) has a sun roller shaft coincident with the output shaft. Through the planet roller reducer (40) and a two-stage reducing gear mechanism (50) for further reducing the output of the planet roller reducer (40), a torque of the motor (31) is transmitted to a driving chain sprocket (4). Provided that the torque of the motor (31) exceeds a predetermined pedaling torque level, the torque is transmitted to the driving chain sprocket (4).

Driving unit for an electric motor driven bicycle

An elevator hoisting device including a stator forming a primary side of a linear motor disposed on an wall of a hoistway adjacent to its ceiling, a tape-shaped amorphous metallic member for hanging down over a pulley to support at opposite ends thereof an elevator car and a counter weight so as to cause its pendent portion connected to the counter weight to be close to the stator through a non-magnetic member with a low coefficient of friction to form a secondary conductor of the linear motor. The non-magnetic member and therefore the adjacent surface of the stator is somewhat tilted to the vertical downward toward the wall of the hoistway.

Elevator hoisting device

A traction elevator apparatus characterized in that a deflector wheel is disposed in a manner to lie below a driving sheave, and that a rope wound on the driving sheave is extended over the deflector wheel in a manner to cause the cage side and balance weight side parts of the rope to cross each other on the lower side of the driving sheave.

Traction elevator apparatus

A wire rope for use in a traction type elevator system is coated with a soft-solid agent or a greasy agent having a drip temperature higher than 55.degree. C. and exhibiting physical properties such that it is evaporated in an amount less than 1 weight percent at 105.degree. C. for an interval of eight hours and elevates the coefficient of friction or traction between the wire rope and the drive sheave when coated on the wire rope.

Traction type elevator system

An apparatus for operating during earthquake which should be stopped to prevent an accident by detecting earthquake is provided. The apparatus detects an initial slight earthquake shock to perform a preliminary operation for earthquake by a first control device. When higher vibration is not detected within a specific time, the apparatus is reset. When high vibration is detected, an operation for earthquake including the stop of the apparatus is performed by a second control device.
