Abstract: A fuel injection pump for internal combustion engines of the type having a plunger adapted to be reciprocatingly moved within a barrel to pressurize and deliver a fuel before the establishment of communication between a fuel relief bore formed in the wall of said barrel and a fuel pressurizing chamber, said plunger being adapted to be rotated relatively to said barrel to change the timing of establishment of said communication thereby to adjust the amount of the fuel delivered per stroke of said plunger.Said fuel injection pump is provided with a plunger rotating member coupled to said plunger for rotation therewith.Whereby said plunger can be rotated by merely rotating said plunger rotating member.

Abstract: A self-regulating electric heater includes a casing made of ceramic and a heating unit housed in the casing. The heating unit includes a PTC body for generating heat when electric current is supplied, heat dissipating plates essentially made of brass and coupled to the PTC body in such a manner as to sandwich the PTC body between the heat dissipating plates and terminals connected to each of the heat dissipating plates for the external electrical connection. The self-regulating electric heater further includes lid member and sealing member for sealing the casing hermetically.

Abstract: An automatic sewing machine includes means for advancing a work piece having a plurality of contiguous edges connected together in angular relationship to each other to sew such edges in succession, a table supporting the workpiece and having an arcuate side face along which the workpiece is guided, and a feed mechanism provided below the table along the arcuate side face for frictional engagement with a portion of the workpiece which hangs from the table. The feed mechanism is driven to turn the workpiece in such a manner that when a first edge of the workpiece has been sewn, a second edge of the workpiece contiguous to said first edge is aligned with the advancing or feed direction of the workpiece.

Abstract: A fuel injection pump for Diesel engines comprises a plunger unit in the pump body, a delivery valve, and an injection-quantity control mechanism in the pump body between the plunger unit and delivery valve. The control mechanism has a piston slidable in the pump body and communicated with the plunger unit and delivery valve and also has an injection-quantity control member coaxial with the piston and axially adjustable in position to press the piston against the pump body with the aid of a spring on the other end of the piston. The lift limit distance of the piston to be adjusted by the injection-quantity control member is preset to a range not less than that obtained by dividing the quantity of fuel to be injected at the engine start by the cross sectional area of the piston.
