IPC: B63B35/73
Filed: 1985-05-20
Abstract: PURPOSE:To improve deceleration ability of a boat and exhibit improved operational performance upon steep turn, by providing a retractable resistance plate at a bottom of the boat which plate is projectable by a handle operation by an operator. CONSTITUTION:A retractable resistance plate 13 is provided at a bottom 12 in such that it is slidable on guides 15 provided on both sides of a body in a direction of an arrow A, and is upwardly biased by tension springs 16 provided between the plate and the body.

Abstract: PURPOSE:To realize the reproduction of an excellent animation picture not causing disturbance of picture when a frame of the animation picture is changed by providing an auxiliary track to a magnetic recording medium and an auxiliary recording and reproducing means to record and reproduce a signal on the track. CONSTITUTION:A reproduced output of main heads 2a, 2b is demodulated by selecting a contact (a) of a switch 5 at first and also tuning on a switch 9, this reproduced output is amplified by an amplifier 4 at the same time and recorded on an auxiliary track 1a by auxiliary heads 3a, 3b. When a counter 11 detects that a magnetic disc 1 is rotated twice, the switch 5 is changed over to a contact (b), the switch 9 is turned off to reproduce the still picture recorded just before from the auxiliary track 1a by using auxiliary heads 3c, 3d. While the reproduction utilizing the auxiliary track 1a is performed, the main head 2 is moved to a track where a still picture to be reproduced next is recorded. When the counter 11 detects the rotation of a prescribed number of times, the similar operation is repeated to the next track to prevent the disturbance of the reproduced picture of the main head 2 during movement.

Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To make the plane sizes of a car and a hoistway when a balance weight is provided equal to those when no balance weight is provided by providing the balance weight, and arranging a pulley to be hooked with a rope for suspending the balance weight inclinatorily against the axis of the hoistway plane. SOLUTION: If a moving pulley 14 is arranged in parallel with the axis Y of a hoistway plane without changing the hanging point C3 of a balance weight rope fitted to a beam 101, the hanging points of the moving pulley 14 and a fixed pulley 9A are drifted, the pulleys 14, 9A are twisted, and the balance weight rope is apt to be disconnected. A fixed pulley 9 to be hooked with the balance weight rope or the moving pulley 14 is arranged inclinatorily against the axis Y of the hoistway plane to prevent this problem, therefore the plane size of a car 1 and the plane size of a hoistway 100 can be made equal to those when no balance weight is provided without drifting the hanging point C3 of the balance weight rope.

Abstract: PROBLEM TO BE SOLVED: To simplify a design of a building core section by employing a car supported through a rotary mechanism with a drive member to be vertically circulated within a shaft, and a car rotating motor for rotating the rotary mechanism. SOLUTION: A pair of suspension members 16 and a car rotating motor 17 are secured to a rotary frame 15. A drive gear 17b attached to a drive shaft 17a of the car rotating motor 17 engages with a stationary gear 13a of a stationary frame 13. A car 5 having an entrance on one side only is suspended with the suspension members 16. When the car rotating motor 17 is actuated, rotary movement is transmitted through the drive gear 17b and the stationary gear 13a so that the drive gear 17b, while rotating itself, revolves around the stationary gear 13a. As a result, the rotary frame 15 is turned by 180 degrees so that the entrance of the car 5 faces the opposite side, This makes it possible to dispose the car in one shaft and to simplify a design of a building core section.
