A brake structure of a traction machine includes a brake drum which is made rotatable about a shaft disposed on a rotary axis of the traction machine, and an electromagnetic brake unit built in an inner space of the brake drum. The electromagnetic brake unit includes a plurality of movable iron cores, a plurality of brake shoes located on the outside of the individual movable iron cores and joined thereto by connecting members, the brake shoes having curved outer surfaces facing a curved inner surface of the brake drum, and a one-piece formed stationary iron core block. The one-piece formed stationary iron core block has a plurality of stationary iron core portions joined to the individual movable iron cores via compression springs for forcing the individual brake shoes against the curved inner surface of the brake drum via the movable iron cores and the connecting members.

An elevator control device for controllably driving multiple traction units includes position sensors and current supplies. Each of the current supplies includes a position controller for generating a speed command for the corresponding traction unit based on input difference between a common position command for the traction units and a feedback signal derived from an output of the pertinent position sensor, a speed controller for generating a current command for the corresponding traction unit based on an input difference between the speed command generated by the position controller and a feedback signal obtained by differentiating the output of the pertinent position sensor, and a current controller for supplying an electric current to the corresponding traction unit based on the current command generated by the speed controller.

A rotational machine includes a shaft, a rotary member rotatably mounted on the shaft with a bearing fitted between the shaft and the rotary member, an oil seal for sealing the bearing to prevent leakage of lubricant from inside the bearing through its axial end onto a surface of the rotary member, a brake which comes into sliding contact with a contact surface area formed on the surface of the rotary member for arresting rotation of the rotary member, a supporting member fixedly mounted on the shaft face to face with the rotary member forming a gap therebetween, the gap serving as a fluid path through which the lubricant which has leaked over the oil seal is allowed to flow, and an oil stop portion formed at a location in the gap between the oil seal and the contact surface area for impeding flow of the leaked lubricant.

An elevator hoist apparatus includes a stationary frame member, a main shaft, a stationary element disposed to said stationary frame member, a rotary frame member supported on said main shaft and extending in a radial direction in axial opposition to said stationary frame member, a rotary element disposed to said rotary frame member in opposition to said stationary member, a brake unit including a brake portion extending through an opening in said stationary frame member, and a rope sheave disposed to said rotary frame member for rotation therewith. The brake unit includes a brake portion disposed in a hollow portion of the stationary frame member of the stationary member and extending through the opening portion and disposed to the inner circumference of the stationary frame member or the rotary frame member. The magnetic path for the brake unit extends through one portion of the rotary frame member or the stationary frame member. Small-size and high performance are realized.

On the basis of state change information acquired by one of sensor nodes forming a sensor network, an instruction indicative of emitting a signal is issued to another node to acquire a photographed image from a camera. An image processing device identifies the ID and actual position of the node by issuing the signal issuance instruction to the node and detecting a signal obtained from the node from the photographed image. On the basis of personal information stored in a database, the image processing device detects a not-allowed action.

An elevator car panel connection structure for connecting car panels constructing elevator car is provided with a first channel-shaped bent portion disposed along a connection edge portion of a first car panel and having a channel-shaped cross-sectional configuration defining an opening and an inner space with a width larger than that of the opening, and a second channel-shaped bent portion disposed along a connection edge portion of a second car panel and having a channel-shaped cross-sectional configuration defining a base portion width that is larger than the width of the opening of the first car panel and that is smaller than the width of the inner space of the first car panel. The second channel-shaped bent portion is pressure fitted into the inner space of the first channel-shaped bent portion through the opening so that the first and the second channel-shaped bent portion are elastically connected and held together. The first channel-shaped bent portion includes a first side wall, a bottom wall and a second side wall and is disposed along the inner space and the connection edge portion. The second channel-shaped bent portion may have a configuration similar to the first channel-shaped bent portion or may have two side walls folded over one another.

In an elevator apparatus, a cover body is disposed on an opening portion of a top portion of a hoistway. A driving machine for raising and lowering a car and a counterweight is supported by the cover body. The driving machine has: a driving machine main body; and a drive sheave rotated by the driving machine main body. A main rope is wound around the drive sheave. The car and the counterweight are suspended inside the hoistway by the main rope.
