Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To enhance cargo handling efficiency without using a magnet like a conventional way for loading work for loading cold pig iron in bulk from land on to a ship. SOLUTION: A load carrying platform 1 on which cold pig iron 45 in bulk is placed is lifted up by a crane via a spreader 11 on which a cargo handling gear 19 is mounted after the platform 1 is transported to a berth by a trailer. By temporarily placing the load carrying platform 1 within a hold, a rotating part of a chain sprocket 29 of the cargo handling gear 19 is away from a contact part and the chain sprocket 29 becomes freely rotatable. In this operation, the crane is slightly operated and a location of a device housing for a chain 21 is moved to an inclined location. Subsequently, if the load carrying platform 1 is lifted down by the crane, the load carrying platform 1 is inclined and thereby the bulk cargo 45 is lowered down into the hold.  After the load carrying platform 1 becomes empty, a temporary placing is performed again, the location of the device housing for the chain 21 is moved to a balanced location, the load carrying platform 1 is lifted up again and the load carrying platform 1 is returned to the trailer.

Title: Rotary door device for washroom
Inventor: KIMURA MOTOYASU
IPC: E05F1/00
Filed: 1994-10-04
Abstract: PURPOSE: To make effective use of space in a washroom by providing the entrance of the washroom with a turntable, providing a semicircular door plate on the turntable, and rotating the turntable at the time of use so as to protrude the door plate outside. CONSTITUTION: When a user who is about to enter a washroom 2 stands on a turntable 50 and operates a switch, a motor 80 is actuated to rotate the turntable 50 by a half circle. The entrance part of the washroom is thereby closed by a semicircular door plate 10, and the internal space of the washroom 2 is enlarged. After use, the turntable 50 is further rotated to enclose the door plate 10 in the washroom 2. In the case of the motor 80 failing during use (in the state of the door plate 10 protruding from the external wall 3), an auxiliary door 15 is opened for escape. Interlocked with the rotation of the turntable 50, a scraper in a bowl shape trap provided at the lower part of a drain hole 55 is rotated to remove dust, deposit, and the like, thus preventing the clogging of drain. Space can thereby be used effectively.
