摘要： PROBLEM TO BE SOLVED: To provide a cutting method and apparatus by a high density energy beam, a method and apparatus preventing sticking, near a cutting part, of fused deposits which are hard to be removed by a simple removing means because of a relation between the flowing direction of assist gas and the cutting/advancing direction of the high density energy beam, in an apparatus designed to blow off dross and spatters from a cutting section by forming a flow of assist gas crossing a beam irradiation part. SOLUTION: The locus of the beam irradiation part in forming a slot is designed to successively go through a-b-c-d-e-a with a as the starting point. As a result, the assist gas J2 crossing the beam irradiation part no longer flows from the front obliquely with respect to the cutting/advancing direction of the high density energy beam, thereby effectively preventing sticking of the fused deposits which are far from simple removal.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive solenoid valve device and a method of manufacturing the same allowing easy processing of a locking member for locking a spring member and a valve housing for fixing a locking member. SOLUTION: In the solenoid valve device, the valve housing 31 reciprocatively movably houses and supports a spool 40. The spool 40 stops in the position wherein an energizing force of a coil spring 50 for energizing the spool 40 in a linear solenoid 10 direction, a driving force of a shaft 18 pushing the spool 40 when a plunger 17 is attracted into an attraction part 14 by a current supplied to a coil 20, and a force received by the spool 40 from oil pressure in a feedback chamber 37 are in balance. The locking member 51 is pressed into the cylindrical part 32 of the valve housing 31 and fixed in the inner peripheral wall of the cylindrical part 32. The locking member 51 locks the end part of the anti-spool side of the spring 50, therefore adjusting load of the coil spring 50 according to the pressed-in amount.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic driving device capable of increasing attracting force without becoming large-size, and a solenoid valve using it. SOLUTION: A fixed core 13 is integrally formed with a storage part 14 for accommodating and supporting a plunger 17 in a freely reciprocated manner, and an attracting part 16 generating the force of attracting the plunger 17. The storage part 14 supports the plunger 17 in the freely reciprocated manner. The plunger 17 has a movable care 18 formed of a magnetic substance, and a cup 20 fitted to the movable core 18. The cup 20 is integrally formed with a cylindrical part 21 covering the outer peripheral side face of the movable core 18, and a bottom part 22 covering the attracting side end face of the movable core 18. An air gap between the magnetic parts of the storage part 14 and movable core 18 can be reduced by minimizing the thickness of the cup 20. Attracting force for attracting the plunger 17 can thereby be increased without increasing the turns of the coil 20.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a high-pressure fuel pump equipped with a pump housing that reduces the number of parts and assembling man-hour and has high strength of a slide part and a high-pressure part and high reliability.
SOLUTION: The housing base material of the pump housing casted by lost-wax process is placed in argon atmosphere of 1200°C and 1000 atm for four hours so that the housing base material is subjected to HIP (High Isostatic Pressing) processing. After the HIP processing, a screw thread is cut and processed with a cutting tool or the like in a part of the housing base material where it is screw-joined with another part. The housing base material is then quenched by heat-treating (QT) the housing base material and the hardness of the housing base material is increased. The screw part of the housing base material to be screw-joined with the other part is then annealed to reduce the hardness of the screw part and a cylinder inner peripheral surface of the housing base material is ground with a grinding tool. The other part is assembled to the pump housing thus formed to manufacture the high-pressure pump.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of the solenoid 23 of an electromagnetic valve. SOLUTION: A stationary magnetic part which attracts a plunger 7 in the axial direction as magnetized by the magnetomotive force of an electromagnetic coil 3a is divided into a bottomed cylindrical case-like yoke 5 provided with a thick-walled part 51, along its inner circumference edge in the axial (cylinder) direction and a nearly cylindrical stator core 6 provided with a flange 62 along its other outer circumference edge in the axial (cylinder), by which a stator structure which does not require an expensive split-type die structure can be obtained. According to this setup, the manufacturing cost of the stator core 6 can be reduced, without having to increase that of the yoke 5. Only the fitting parts 56 and 57 of the yoke 5 and the fitting parts 63 and 64 of the stator core 6 are improved in dimensional accuracy, by which a magnetic gap between the inner diameter surface of the yoke 5 and the outer diameter surface of the stator core 6 can be stopped. With this setup, a solenoid 23 can be improved in product performance, especially in magnetic efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve miniaturizable without reducing the attracting force and preventing the leakage of a fluid to the outside of a nonmagnetic member. SOLUTION: The inside cylindrical part 11a of a yoke 11 covers the outside surface of a movable element 21. The inside cylindrical part 1a of the yoke 11 and the attraction part 12a of a fixed core 12 are opposed through a clearance 19 of a prescribed length formed in the reciprocating direction of a movable member 20. The nonmagnetic member 25 is arranged on the inside of the yoke 11 and the fixed core 12 to reciprocatingly support the movable element 21. The nonmagnetic member 25 covers one reciprocating-directional end of the movable element 21 and also covers the clearance 19 formed between the attraction part 12a of the fixed core 12 and the inside cylindrical part 11a of the yoke 11.

摘要： PROBLEM TO BE SOLVED: To provide a flow passage selector valve with a shorter axial length. SOLUTION: On the peripheral wall 32 of a housing 31, an input port 33; the first input/output port 34; and the second input/output port 35; are formed by penetrating the peripheral wall 32. On the outer peripheral wall of a spool valve member 40, an input passage 41 and an input/output passage 42 are formed. The width d2 of the peripheral wall 32 partitioning the first input/output port 34 and the second input/output port 35 is the same as the width d1 of the input port 33 or less than that, while the width of the input/output passage 42 is narrower than the width of the input passage 41. Furthermore, since a ball 52 is fitted to a groove recessed part 36 farmed to the housing 31, and the groove recessed part 46 formed to the spool valve member 40, the rotation of the spool valve member 40 is prohibited to the housing 31. As a result, the axial length of a flow passage change-over part 30 can be made shorter.
