摘要： PURPOSE:To provide a coolant bypass free from such problems as loosening or separation of parts by locating a water pump and a thermostat in a place which as a wall surface approx. perpendicular to a cylinder block in its position close to the corner. CONSTITUTION:A water pump 7 is furnished at the wall surface on one cylinder bore 21 side of a cylinder block 2 in such a location as close to the corner formed with another wall surface approx. perpendicular which is the upper part of the cylinder block 2. A thermostat 8 is installed in the upper part of the wall surface of the cylinder block 2 approx. perpendicular to the mounting surface for water pump 7, and the mounting surface for the thermostat 8 is located close to this mounting surface for water pump 7. Thereby the cylinder block 2 and the coolant bypass shortcircuiting from cylinder head side to water pump 7 side can be formed within the cylinder block 2 and cylinder head. This enables elimination of using such parts as rubber tube or clamp for the bypass.

摘要： PURPOSE:To facilitate the ignition timing control with a simple mechanism by oscillating an oscillation member magnetically in response to the revolution of a disk which is turned synchronously with an engine and moving an ignition trigger coil. CONSTITUTION:When an engine is driven to turn a crankshaft, a disk 10 is immediately turned counterclockwise. An electro-magnetic force moving each of a plurality of magnets 13 and 14 toward the disk 10 is generated between both the vortex current generated at the disk 10 and the magnetic field of each of the magnets 13 and 14. An oscillation board 12 is oscillated clockwise through the center of a support pin 11 against the load of a spring 16. The oscillation of the oscillation board 12 causes another oscillation board 20 to be oscillated counterclockwise through the center of a support pin 21 via a link 24. As a result, a magnet and a pulser coil which are attached to the end of the oscillation board 20 and not illustrated in the drawing are moved in the direction of having the spark advance with respect to the turn of the disk 10.

摘要： PURPOSE:To spread the set degree of freedom in control and improve precision by constituting a governor from a disc consisting of a nonmagnetic body which revolves in synchronization with the revolution of an engine and a magnet which generates an electromagnetic force for swinging a swing member according to the revolution of the disc. CONSTITUTION:When a disc 3 consisting of a nonmagnetic body which revolves in synchronization with the revolution of an engine revolves, an electromagnetic force nearly proportional to the engine revolution speed is generated between an electric eddy current generated on the disc 3 by a magnet 6 and the magnetic field generated by the magnet 6. When the engine revolution speed is equal to a set value, the electromagnetic force acting onto a swing arm 5 and the pulling force of a spring 7 are made equal, and the swing arm stops at a constant position. When the engine revolution speed increases over a set revolution speed, the electromagnetic force acting onto the swing arm 5 increases, and the swing arm 5 is swung in the revolution direction of the disc 3, and a throttle valve is turned in the closing direction.

摘要： PURPOSE:To adjust the engine with the linear governor control characteristic accurately and responsively by relatively positioning a rotor and an oscillating member such that the rotation axis of the rotor and the oscillating shaft of the oscillating member are on the coaxial line. CONSTITUTION:When a disc 2 is rotated to the direction A simultaneously with the rotation of an engine, eddy current is generated at the disc 2 by the magnetic field formed by a permanent magnet 5, and the electromagnetic force for oscillating an oscillating member 4 in the rotating direction of the disc 2 between the eddy current and the magnetic field of the permanent magnet 5 is generated. The extent of the generated electromagnetic force is approximately proportioned to the speed of the disc 2, that is, the engine speed, and the oscillating member is oscillated opposing to a governor spring 6 so as to adjust the engine. In this case, as the disc 2 and the oscillating member 4 are relatively positioned such that the rotation axis 1 of the disc 2 and the oscillating shaft 3 of the oscillating member 4 are on the coaxial line, the rotating direction of the disc 2 coincides with that of the oscillating member 4 so as to obtain the rotating force of the oscillating shaft 3 proportioned to the engine speed.

CONSTITUTION:There is provided a multi-pole type (for example, eight pole type) rotor including a plurality of magnets 4 is attached to a flywheel 2 on a crankshaft 1. Further, there is provided a projecting pole type stator having cores 5 confronting the magnets 4 with a predetermined gap therebetween and each wound thereon with a plurality of windings 6. A flywheel magnet type generator is composed of the rotor and the stator. An arm 10 is attached to a holding member 7 for attaching the stator to a stationary side boss 9. Further, an arm 13 is supported to the boss 9 through the intermediary of a bearing 12, having its front end attached with a self-trigger type ignition unit 14, and the arms 13, 10 are associated with each other through the intermediary of a link mechanism 16.

摘要： PURPOSE:To offset an inertia couple generated by means of a reciprocating mass as the weight of an engine is decreased, by a method wherein a balance weight mounted on the base end side of the arm part of a crank shaft is eliminated, and the balance weight is mounted to each rotary member. CONSTITUTION:A fan-shaped balanced weight 55 is mounted in the spot of a drive gear 41 located far side in a 90 deg. arc from the top dead center of a second cylinder 13-2, and a lunate balance weight 53 in the spot of a fly wheel cylinder part 33A located this side in a 90 deg. arc from the top dead center. Thus, an inertia force produced by means of a reciprocating mass can be balanced by displacing a top dead center between cylinders 13 in a 120 deg. arc. Further, an inertia couple by means of a reciprocating mass can be offset by means of the balance weights 53 and 55. The balance weights 53 and 55 are mounted to a fly wheel 33, having radius larger than that of a crank shaft 23, and a drive gear 41 and situated in a spot away from a cylinder center 19, resulting in reduction of a mass. This constitution enables off setting of the inertia couple as the weight of an engine is decreased.

摘要： PROBLEM TO BE SOLVED: To provide a connector of simple structure, reduced in the number of part items, operated easily, and of which the contact is separable from an insulator. SOLUTION: A condition where a plug connector 1 is engaged with a receptacle connector 11 is indicated, a protrusion 4C of each lance 4 provided in the plug connector is locked to a recess 3A of each contact 3 in the plug connector, and the tip of each contact 13 of the receptacle connector is inserted into a hole 3B of the tip of the each contact 3. When a current flows in each heater wire 5, a shape memory alloy 4A in the each lance 4 is heated to be deformed into a predetermined shape. The protrusion 4C in each locking part 4B is thereby separated from the recess 3A in each contact 3. Resultingly, the each contact 3 is extracted from the insulator 2 of the plug connector.

摘要： PROBLEM TO BE SOLVED: To solve the problem that an insert fitment 4 is difficult to be removed at a recycling time because the fitment 4 prevents a creep deformation of a resin 5 by a clamping axial force of a bolt 2 and a recess and a protrusion provided on a periphery of the fitment 4 are provided to be engaged with the resin 5. SOLUTION: A tapered surface for radially enlarging from one toward the other is formed on a resin connecting surface 4b of the insert fitment 4. When an impact force is given to a small diameter side 4c at the recycling time, the fitment 4 is easily released to a large diameter side 4d, then removed to provide excellent recyclability. At a clamping time, an object 3 to be clamped is contacted with both the fitment 4 and the resin 5, and the fitment 4 does not have a fault of being released from the object 3 side. A washer 6 is contacted with both the fitment 4 and the resin 5, and the fitment 4 does not have the fault of being released from the washer 6 side.
