Title: Optimizing method of ignition angle of in-line engine and in-line engine
Inventor: ERIKU KIBUISUTOGARUDO
IPC: F02P5/15
Filed: 1995-04-21
Abstract: PURPOSE: To optimize the ignition angle by bringing the first-grade and the second-grade inertial force into an independent state in the manner reducing oscillation parameter of an engine. CONSTITUTION: An in-line engine 1 involves a plurality of cylinders having pistons 7 respectively connected to crank throws linked on a shared crankshaft 12. The crank throw is positioned at a prescribed angle position corresponding to the ignition angle of a cylinder and adjusted to at least two different values within the angle difference (αj -αj-1 ) between the ignition angles of the cylinders ignited successively. At this time, the first-grade inertial force of the engine 1 is brought into a non-equilibrium state and, if the mass in reciprocating motion of a cylinder is equal, the second-grade inertial force is brought into an unequilibrium state. At least two cylinders are then adjusted so as to be different from the mass in reciprocating motion of other cylinders, therefore the first-grade inertial force is brought into an equilibrium state.  It is thus possible to reduce the selected oscillation parameter and bring the first- and second-grade inertial forces into an independent state for optimizing an ignition angle (α).

Abstract: PURPOSE:To prevent the occurrence of energy loss due to yielding of an eddy current, by a method wherein an amorphous film used for a magnetic shield is adhered to the outer periphery of an externally-rolling yoke. CONSTITUTION:An externally-rolling rotor 3, provided at the inner periphery of a externally-rolling yoke 1 with an outer magnet 2 with plural poles, in which an N-pole and an S-pole are aligned alternately, is extended from a drive source. An internally-rolling rotor 6, provided at the outer periphery of an internally- rolling yoke 4 with an inner magnet 5, corresponding to the outer magnet 2 in which N-poles and S-poles are alternately aligned on the outer periphery of an internally-rolling yoke 4 disposed in a hollow part at the axis of the externally- rolling yoke 1, is extended from a follower object. An amorphous film 8 with high permeability is firmly adhered to the outer periphery of the externally-rolling yoke 1. This causes magnetic flux, leaking through the externally-rolling yoke 1, to leak in the amorphous film 8, but since the amorphous film 8 is extremely high in permeability, the leak-in phous film 8 is extremely high in permeability, the leak-in magnetic flux is returned from the inside of the amorphous film 8 to the externally-rolling yoke 1 agains.

Title: Image recording device
Inventor: OTSUKA KAZUO
IPC: G03G15/00
Filed: 1988-04-19
Abstract: PURPOSE:To provide separability for a recording medium from an image bearer without disturbing a transcribed developer image, by setting the line speed of a feeder part, which delivers recording medium to the image bearer, to a level a little larger than the line speed of the image bearer. CONSTITUTION:The line speed of a feeder part roller 9 is set a little higher than that of a photo-sensitive drum 1. This produces a slack of a recording sheet 14 between the feeder part roller 9 and a transcript pole 5, and the photo- sensitive drum 1 and recording sheet 14 are put in close contact with each other in the transcript region where the transcript pole 5 with high pressure impressed in acting, and thereby the width of the substantially effective transcript region can be increased, and a toner image turned apparent can be transcribed on the recording sheet 14 without generating dust. The slack of recording sheet 14 absorbs variation in the line speed of the photo-sensitive drum 1 and feed roller 9 due to varying load and mechanical vibration, to prevent shift of the recording sheet 14 relative to the photo-sensitive drum 1, and the toner image apparent thereon can be transcribed without disturbance in the image.
