Abstract: PURPOSE: To improve tracing accuracy by providing a position deviation detecting means for torch to the torch end.  
     CONSTITUTION: Sensors 11 are mounted near the arc 10 of the torch 3 inserted into groove 2, for example, on its both side faces. These detect the distance between the torch 3 and the inside wall surfaces 1a, 1b in the groove. Microswitches which actuate when contact the foregoing wall surfaces through movement, differential transformers or rangefinders of noncontact type are used for the sensors 11. Or fluid elements and the like which detect the back pressure of the time when shielding gas for MIG welding is spouted to the foregoing wall surfaces and detect the distance between the torch and the foregoing wall surfaces are used. The control method is such that in case the sensor 11 is, for example, one side alone, the detection signal for the distance between the sensor and inside wall surfaces of the groove from the sensor 11 is compared with the reference signal from a reference signal setter 12 coinciding with the groove center position, in a comparator 13. This is amplified to let a servomotor 8 run in either of forward or backward direction, whereby the torch is moved in the groove width direction.

Title: Diesel engine with swirl chamber
Inventor: KIZAKI YOSHIO
IPC: F02B3/06
Filed: 1981-05-06
Abstract: PURPOSE:To improve the combustion in a main combustion chamber and shorten the time of generation of white smoke at the starting in the cold state, by orienting the combustion gas from an auxiliary combustion chamber toward a cavity. CONSTITUTION:A cavity 12 is provided on the bottom of a cylinder head 2 or/and on the top of a piston 3 so that the cavity faces a main combustion chamber 4 and is located near an exhaust valve 10 and combustion gas ejected from an auxiliary combustion chamber 5 is oriented toward the cavity. Because of such structure, the area of the cavity 12 is small. For that reason, the depth of the cavity 12 can be made larger. Since the combustion gas from the auxiliary combustion chamber 5 is concentratedly injected into the cavity 12, the gas flow in the cavity is so rapid and intense that the gas instantaneously mixes with all the air in the cavity. Since the temperature of the cavity 12 rises quickly at the starting of the engine in its cold state, the generation of white smoke at the starting is reduced.
