摘要: A rivet head forming tool has a base body having a recessed hole slanted outwardly from the center of the lower end thereof. A cylindrical body is fitted securely in the recessed hole, and a forming shaft having an annular groove at the upper portion thereof is rotatably mounted in the cylindrical body. A collar having a shoulder on the inner periphery thereof is mounted between the bottom of the recessed hole and the cylindrical body, the forming shaft being inserted in the collar and being retained by means of a spring rod inserted between the inner periphery of the collar and the annular groove of the forming shaft.

摘要: Vertical deflection and picture position adjusting circuits are provided for color television receivers. These circuits include a vertical output transformer having a primary winding to which is supplied a sawtooth wave from a vertical output element, and a secondary winding for supplying vertical deflection current to a vertical deflection coil. Feedback is provided from a circuit including the deflection coil and secondary winding to the vertical driver stage connected thereto for the purpose of compensating linearity. A vertical deflection and picture position adjustment arrangement provides that the primary winding and secondary winding are isolated from each other in a DC sense. Also current is supplied to the vertical output element from a first DC source. In a first type of circuit of the invention, a first loop circuit is formed by said secondary winding, the vertical deflection coil, a feedback resistor associated with the vertical driver stage, and a capacitor which passes the vertical deflection current. A second loop circuit is formed by said secondary winding, said vertical deflection coil, a choke coil for blocking vertical deflection current and a variable resistor. The brush of the variable resistor is connected to a second DC source, and load circuits are connected to the respective terminals of said variable resistor in a DC sense or alternatively a switchable load circuit is connected selectively to said variable resistor. A third DC source is provided for supplying DC current to said vertical driver stage via said feedback resistor. Current feedback is supplied to said driver stage through said feedback resistor when vertical deflection current flows through said first loop circuit. The value and direction of the DC current which will flow in the vertical deflection coil when DC current is supplied to said load circuit(s) from said second DC source by way of said second loop circuit are determined by said variable resistor whereby the picture position is adjusted. In a second type of circuit of the invention, a series circuit is formed by said secondary winding and vertical deflection coil and an AC loop circuit is formed by said series circuit and a feedback resistor associated with the vertical driver stage and capacitor. One terminal of said series circuit is connected to said third DC source via a DC current shunting circuit. The secondary winding is connected via a DC current shunting, variable resistor to said second DC source whose potential is higher than that of said third DC source. DC current is supplied to said vertical driver stage from said third DC source through said feedback resistor. Current feedback is effected to said driver stage by using said feedback resistor when vertical deflection current flows through said AC loop circuit. The value and direction of the DC current flowing in the vertical deflection coil are determined by said variable resistor. Unidirectional conductive elements are connected between said second and third DC sources and form a stabilizing circuit for keeping the voltage ratio between the two DC sources constant.

摘要: A shaft moving device for elevating and lowering an operating shaft in a riveting machine. The device has a cylinder, a cylindrical member slidable up and down in the cylinder and a coaxially and rotatably supporting the operating shaft. The cylindrical member has an annular ring which also serves as a piston. A pump supplies pressure oil to the cylinder. A directional control valve is provided for selectively switching the oil supplied to the cylinder. Upper and lower ports are provided in said cylinder and are connected with the pump through the valve. The cylindrical member together with the operating shaft can be lowered and elevated by the actuation of the valve.
