Title: Step motor driver
Inventor: KUNO MITSUYASU
IPC: H02P8/30
Filed: 1990-08-22
Abstract: PURPOSE:To suppress noise at the time of generation of holding torque by providing means for performing constant current control at the time of rotary driving and for turning a switching element, arranged in a power supply circuit for a motor coil, ON/OFF with a predetermined period at the time of generation of holding torque. CONSTITUTION:When a step motor is stopped and a holding torque is generated, a phase exciting signal phi repeats Hi and Lo levels before a coil current for inverting a monostable multivibrator 6 to Lo level flows, and thereby a transistor 2 repeats ON/OFF with the period of the phase exciting signal phi with a constant current control means 7 being disabled. Since it means that the motor coil 1 of any phase is turned ON/OFF with an identical period, beating phenomenon does not takes place even if the coil constant of each motor coil is different between the phases. According to the constitution, noise causes no anxiety even under a condition where the motor is stopped and driving noise is not generated from the load.

Title: Hull mounting structure of outboard motor
Inventor: TAKAHASHI MASAAKI
IPC: B63H20/02
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To avoid interference with a hull at the time of tilting up and improve the weight balance with the hull by directing a cylinder head of an engine to the rear of the hull in the sailing condition, and positioning a crankshaft in the front of the hull from a pivot shaft. SOLUTION: An outboard motor 1 is so constructed that cylinder heads 18a, 8b are directed backward and rotatably pivoted on a pivot shaft 6. The pivot shaft 6 is provided substantially in the middle on a line connecting between a crankshaft 16 and a driving shaft 54 in a plan view. That is, the driving shaft 54 is disposed in such a manner as to be offset more back side of the hull than the pivot shaft 6 relative to the crankshaft 16. Accordingly, the turning radius (r) to the outer edge of an outboard motor 1 centering round the pivot shaft 6 is decreased, so that when the outboard motor 1 is turned only at the maximum steering angle θ, a cowling 11 is not brought into contact with the side 102b of a recessed part 102, and it is not necessary to enlarge the dimension in the lateral direction of the hull of the recessed part 102 and decrease the maximum steering angle θ.  Further, as the center of gravity of an engine 10 approaches the pivot shaft 6, the weight balance with the hull can be improved.

Abstract: PURPOSE:To improve stability of rotation in an idling operational condition by providing such constitution as suppressing elastic deformation of a spring for increasing starting fuel quantity of a fuel quantity adjusting tool by means of an elastic deformation suppressing means in a starting fuel quantity increasing range. CONSTITUTION:A variation rate of tensile force of a start spring 9 is small since both springs 11, 12 for starting increase quantity and idle rotation act in the state of serial connection, during the period that a fuel adjusting quantity tool 2 reaches from the starting fuel increase quantity position Qs to the vicinity of the full load position Qf. An elastic deformation suppressing means 14 caves in operation in the vicinity of the full load position Qf, and the spring 11 for increasing starting fuel quantity is not elastically deformed any more. The variation rate of tensile force of the start spring 9 is made large since only the spring 12 for the idle rotation is put in operation during the period from the full load position Qf to the no load position Qs. The start spring is not operated sensitively in response to slight variation of governer force GS, and the fuel adjusting quantity tool is controlled in its operation slowly.
