Title: Rolling restraining device for marine structure of ship
Inventor: ITABASHI MASAYASU
IPC: B63H9/08
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To restrain a rolling and pitching without the drop of a ship speed by moving a weight provided on a mast elevatingly upward/downward by a vertically moving device at the sailing time. SOLUTION: A mast is provided at a position passing nearly the gravity center of a ship 10 on the deck 13 of the ship 10 and a wing sail 15 is provided turnably on the mast. The wing sail 15 is connected to a servo mechanism 17 through a link mechanism 16 and can adjust the attack angle freely by the servo mechanism 17. The weight 21 in the mast is moved vertically in response to the rolling of the ship 10. When the ship 10 produces the rolling by the external disturbance such as a wave during the sailing, the weight 21 in the mast is moved vertically and by controlling an inertia moment, the swing of the ship 10 is restrained. At the same time, the rolling is restrained by the operation of the attack angle of the wing sail 15 and the action of the moment force for denying the rolling.

Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To make a dedicated machine and a general program which have mutually different communication methods exchangeably connectable, even if communication interface connection terminals are unified into one, by allowing a programmable controller to decide the kind of a programming device according to whether or not there is a recognition signal. SOLUTION: On the programmable controller side, a timer measures the time from the transmission of an answer signal to the next transmission of information from a programming device (rotor/general personal computer) at a connection destination. On a general personal computer side, on the other hand, since data transmission timing is set longer than a certain time irrelevantly to whether or not there is the answer signal, when a protocol 3 is not received within the certain time, it is determined that the connection destination is a general personal computer. The personal computer carries out a communication thereafter by a communication method corresponding to the decided kind of the programming device.

Title: Fall preventing mechanism for paper cassette
Inventor: MORIYA TOSHIBUMI
IPC: B65H1/26
Filed: 1986-06-09
Abstract: PURPOSE:To prevent a cassette from falling by restricting the vertical direction of a cassette with a rail and engaging the recessed and projecting stoppers provided on a body and said cassette respectively in a condition that the position of said cassette is restricted by said rail with its center of gravity being out of a machine. CONSTITUTION:When a cassette 1 is drawn out of a body 4, a stopper projection 5 is brought into contact with a stopper recess 6 at a contact point A, and a paper cassette 1 is temporarily stopped. At this time, since the center of gravity 8 of the cassette 1 is on the outside of a contact point B, the paper cassette 1 is rotated centering around the contact point B and the rotation is stopped with the cassette being brought into contact with a contact point C. Thereby, both hands of an operator can be freed enabling him to shift the hands to the part out of the body 4 of the cassette 1. Accordingly, the cassette 1 can be drawn out by lifting it up vertically and disengaging the projection 5 from the recess 6. By this structure, the cassette 1 can be prevented from falling.
