There is provided a small printer capable of effecting printing in two colors by a simple structure. The small printer comprises a base formed in a cylindrical shape, a plurality of places of printing type belts mounted on the outer peripheral surface of the base, two sets of printing type groups of the same pattern formed on the printing type belts circumferentially thereof, hammer units corresponding to the printing type belts and contained in the base, and a pair of ink rollers capable of app...

A small motor has a substantially disc-shaped rotor body carried by a rotor shaft and provided with a plurality of coils, a substantially doughnut-shaped permanent magnet disposed in close proximity of one side face of the rotor body, and a commutator mounted on the part of the rotor shaft in the aperture of the permanent magnet. The part of each coil adjacent to the commutator is bent away from the stationary magnet to provide a recess through which the coil end can be led to increase the effec...

An improved fuel delivery and injection system for a small watercraft engine reduces the heat effects within an enclosed engine compartment upon various components of the engine and upon the fuel within the fuel system. The fuel system integrates a fuel pump within a fuel tank at a location which minimizes the effects of watercraft leaning. The inlet of the fuel pump desirably corresponds, in the lateral direction, with a position of an inlet to the jet pump unit. In this position, the pump is l...

Several embodiments of small vehicles having a relatively narrow body frame assembly supporting front and rear wheels at its ends through suspension systems. A single seat is carried by an upwardly extending rearward portion of the body frame assembly. The body frame assembly is narrow so that a person can stand beside the seat and lower himself into it without having to climb into the vehicle. Various battery arrangements are disclosed all of which have the batteries disposed so that they are i...

A small watercraft includes a four-cycle engine which is arranged within a hull of the watercraft to enhance ventilation of and air induction into the engine. The hull includes at least one air duct which opens into an engine compartment within the hull at a level below an upper rim of the flywheel. A case cover of the flywheel assembly acts as a guide to direct at least a portion of the air flow, which enters the engine compartment at this location, upward over the engine and toward the engine'...

A watercraft has a center part of the aft deck protruding upwardly to form a saddle, and the top of the deck in front of and on both sides of said saddle is formed into a continuous U-shaped stepping surface so that the operator sitting on the saddle can operate the craft with his/her legs stretched forward. Preferably, the lower part of the saddle is formed into an engine compartment so as to collectively arrange an engine, an oil tank, a muffler and other auxiliary parts inside the engine comp...

A small antenna comprises a first meander part formed in such a manner that a meander conductor travels to a first direction and having a first end and a second end, and a second meander part formed in such a manner that a meander conductor travels to a second direction different from the first direction and having a first end connected with the second end of the first meander part and a second end.

A small printer is disclosed which contains a character member, such as a character ring or a character belt. The character member comprises a plurality of character bodies which are connected by coupling portions and which comprise dot-like projections which form dot characters. The small printer also has a device to rotate the character member in order to place a desired dot character body which contains the dot character to be printed between a hammer and a piece of paper. Subsequently, the h...

A small antenna comprising a dielectric substrate, a radiation element provided on one major surface of the dielectric substrate, a ground element provided on the other major surface of the dielectric substrate. A feed point on the ground element is located at a position where a voltage of a standing voltage wave induced on the ground element becomes minimum. The antenna may be further provided with a short-circuit element for electrically connecting one ends of the radiation and ground elements...

A small antenna including a dielectric plate, upper and lower conductive plates provided on upper and lower faces of the dielectric plate, respectively, a plurality of conductive reactance posts for connecting, at first positions of the dielectric plate, the upper and lower conductive plates to each other, and a feed point provided at a second position of the dielectric plate such that first and second plane-parallel plate transmission lines separated from each other by the reactance posts are f...
