  • Publication number: 20260171052
    Abstract: A method for processing information, the method includes: identifying a position and an orientation of a musical instrument based on a first detection signal output from a first sensor configured to detect the position and the orientation of the musical instrument, the musical instrument being a real musical instrument used by a real user; identifying a playing operation of the real musical instrument made by the real user based on a second detection signal output from a second sensor that detects the playing operation of the real musical instrument; controlling, based on the identified position and the identified orientation of the real musical instrument, a position and an orientation of a virtual musical instrument used by a virtual user; and controlling, based on the identified playing operation of the real musical instrument made by the real user, a playing operation of the virtual musical instrument made by the virtual user.

  • Patent number: 6062923
    Abstract: A tilt-trim device (17) for a marine propulsion unit comprises a cylinder means 18 with a rod guide (29) is fixed to the end portion of an outer cylinder (22) a piston (23)fixed to one end portion of a piston rod (24)is freely slidably disposed within an inner cylinder (21) and a hydraulic fluid is filled within the cylinder; and the piston rod passes through the rod guide; a tank device (20) in which the hydraulic fluid can be stored; and a pump device (19) intended to supply into and discharge from the cylinder device the hydraulic fluid within the tank device, thereby causing the expansion and contraction operation of this cylinder device. In this tilt-trim device, each of the inner and outer cylinders is made of pipe material, and the end portion of the outer cylinder is bent inwardly, whereby the rod guide is fixed to the outer cylinder by bent portion(30).

  • Patent number: 5372528
    Abstract: Tilt and trim cylinders have blind-end chambers connected through a main valve to a first port of a reversible pump. The rod-end chamber of the tilt cylinder is connected through the main valve to a second port of the reversible pump. The rod-end chamber of the trim cylinder is connected to an oil tank. The second port of the pump is connected to the oil tank, and the first port may be connected to either only the main valve or the oil tank through a suction-prevention valve, an orifice, or a pressure relief valve. When the pump is actuated with the tilt cylinder locked to keep an outboard engine in an tilted-up position, the trim cylinder is automatically contracted to withdraw its piston rod. Cavitation in an oil passage from the blind-end chamber of the trim cylinder to the pump is prevented when working oil is introduced from the oil tank to the pump through the orifice or the pressure relief valve.
