Title: Braking force adjusting device for railroad operating vehicle
Inventor: MAAMUUTO KESHIYUBUARIIRASUTEI
IPC: G05D15/01
Filed: 1994-03-30
Abstract: PURPOSE: To use a brake force adjusting device for a rail traveling vehicle even for the rail traveling vehicle having no specific vehicle bus by allowing transmission of a brake signal to a brake control device by a pressure/electrical signal converter through a main air line rather than through a vehicle bus. CONSTITUTION: In this brake force adjusting device for a rail traveling vehicle, a measurement signal of a brake torque sensor 11 provided in a brake link mechanism 6 can be transmitted to a brake control device 13. Thereby, the measurement signal can be compared with a target value signal of a target potentiometer 18 obtained through a vehicle bus 15, and the target value difference signal can be transmitted to a brake cylinder 10 through a valve system so as to control the control torque of brake pads 4a, 4b. The brake signal capable of being pneumatically switched through a main air line 71 can be transmitted to the brake control device 13 by a pressure/electrical signal converter 72 connected to the main air line 71 rather than transmitting the brake signal through the vehicle bus 15.

Title: Electric power source device for direct current arc welding
Inventor: FUKUMOTO NOBORU
IPC: B23K9/06
Filed: 1979-07-03
Abstract: PURPOSE: To make ripple contents approximately uniformly small in a wide electric current regulating range by supplying the electric currents flowing in a phase controlling and rectifying circuit to the reactors which vary with each of polarities and are fixed in a predetermined magnetized state in the nonvoltage application period.  
     CONSTITUTION: Positive and negative electric currents flow to the thyristors 17, 18 of a phase controlling and rectifying circuit 14 depending upon their on and off, but a welding current of always one direction flows in arc welding load 15. On the other hand, the electric current restrained in the closed circuit of a reactor 25 and a thyristor 27 self-excites the reactor 25 to a fixed magnetized state. A reactor 26 is also self-excited in a similar manner. And it turns out that the electric current flowing to the load 15 since the time when the thyristors 17, 18 conduct rises from the current value led from the fixed magnetized state of the reactors 25, 26. Hence, if the flux fixing positions of the reactors 25, 26 are set high and if the fixed points and the maximum points of the magnetized state are selected in regions where magnetic flux does not saturate relatively, the DC welding current may be made to the one of less ripple contents.

For example, an ultrasonic vibrator 2 is attached to an edge 1 of a kitchen knife, and a pipe is covered on this vibrator, setting it down to a haft 3. In succession, the ultrasonic power is supplied with a high frequency generator 4, and the ultrasonic vibration is generated in the vibration system consisting of the edge 1 and the vibrator 2.
