A dental paste filling device for filling dental paste in a container without entraining air bubbles is disclosed. The dental paste filling device includes: a paste supply stage serving as a supply source of the dental paste; a paste filling stage where the dental paste is filled in the container; and a supply flow passage connecting the both stages. The paste supply stage comprises: a storage chamber for storing the dental paste; a storage chamber depressurizing and defoaming device for depressurizing the inside of the storage chamber to defoam the dental paste within the storage chamber; and a storage chamber extruding device for extruding the dental paste within the storage chamber towards the supply flow passage. The paste filling stage comprises: a filling chamber having an open/close mechanism; a holder for detachably holding the container inside the filling chamber; a filling chamber deaerating device for depressurizing the inside of the filling chamber to prevent entrainment of air bubbles into the dental paste; and a reception port for introducing the dental paste into the filling chamber. The supply flow passage comprises: an upstream tube connected to the storage chamber; a downstream tube connected to the reception port of the filling chamber, and a discharge control valve disposed between the upstream tube and the downstream tube.

Cap for bottle

A hinge cap formed by an injection-molding comprises an inner lid capable of being attached to a container body, a hinge, and an outer lid that is connected to the inner lid by the hinge to open and close the cap. The inner lid includes a claw portion. The outer lid includes a tubular outer wall portion and a plurality of convex portions as undercut portions and a plurality of concave portions. One convex portion and a concave portion adjacent to the one convex portion form an engaging portion capable of being engaged with the claw portion. An adjacent convex portion adjacent to the engaging portion and a concave portion adjacent to the adjacent convex portion form a mold pressing portion.

Stabilization of the engine speed is effected rapidly particularly during idle running because there is provided a generator control means capable of suppressing or stopping power generation of a generator driven by an engine in the event the engine speed decreases below a predetermined value. Additionally, according to the present invention it is also possible to provide means capable of adjusting the amount of intake air fed to the engine combustion chamber, whereby in the event of decrease of the engine speed, for example, during idle running it is made possible to stabilize the engine speed rapidly and surely through control of generated energy for a short time and control of the amount of intake air for a long time. Furthermore, the present invention is applicable also to an operating cylinder number control type engine capable of bringing part of cylinders into a non-operative state.

Engine speed regulating system

A control unit is disclosed for controlling the driving torque of a generator driven by an engine in accordance with the number of cylinders to be operated, thereby to achieve stabilized operation. A voltage regulator is provided for varying the field current through the field coil of the generator so as to regulate the output of the generator. A circuit component including a pair of NC contacts in parallel with a resistor is connected in series between the field coil of the generator and a power source. Depending on the number of cylinders to be operated, the NC contacts are either closed to provide a low resistance path for current to the field coil or are opened to provide a high resistance path through the resistor.
