1. A radiator structure, comprising:
a radiator frame, mounted on a main board corresponding to an electronic element, having a plurality of coupling members and an opening corresponding to the electronic element which has a surface exceeding the peripheral edges of the opening;
a radiator, mounted on the radiator frame, being in contact with the surface of the electronic element and having a plurality of latch sections corresponding to the coupling sections; and
a plurality of elastic latch members coupling on the latch sections and being bent to form a force applying section, a latch arm and a swinging arm, the swinging arm being pivotally engaged with the latch section and turnable after the force applying section having received a force to allow the latch arm to be latched on the coupling section to anchor the radiator on the radiator frame.
2. The radiator structure of claim 1, wherein the radiator frame further includes an another coupling member, the elastic latch member including an another force applying section and an another latch arm such that the another latch arm is engageable with the another coupling member after the swinging arm was turned.
3. The radiator structure of claim 1, wherein the radiator frame further includes a retaining member to confine the radiator in the radiator frame from moving.
4. The radiator structure of claim 1, wherein the radiator frame further has a screw hole for fastening the radiator frame to the main board.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. An apparatus comprising:
a plunger;
a stator that forms a magnetic circuit in combination with the plunger, the stator further defining:
an accommodating portion for supporting the plunger with the accommodating portion so that the plunger is capable of reciprocation; and
an attracting portion, wherein a magnetic attractive force attracts the plunger in a reciprocating direction of the plunger and acts between the attracting portion and the plunger; and
a coil that generates the magnetic attractive force when energized,
wherein either one or both of at least an outer peripheral wall of the plunger and at least an inner peripheral wall of the accommodating portion form(s) a magnetic portion made of nickel phosphide, and
the phosphorus content of the magnetic portion is set within a range of 5% to 15% in mass percentage.
2. The apparatus according to claim 1, wherein the magnetic portion is heat treated.
3. An apparatus comprising:
a cylindrical housing defining a plurality of fluid paths through a peripheral wall thereof;
a plunger;
a stator located adjacent to the cylindrical housing, the stator forming a magnetic circuit in combination with the plunger, the stator further defining:
an accommodating portion for supporting the plunger with the accommodating portion so that the plunger is capable of reciprocation; and
an attracting portion, wherein a magnetic attractive force attracts the plunger in a reciprocating direction of the plunger and acts between the attracting portion and the plunger;
a coil that generates the magnetic attractive force when energized,
wherein either one or both of at least an outer peripheral wall of the plunger and at least an inner peripheral wall of the accommodating portion form(s) a magnetic portion made of nickel phosphide, and
the phosphorus content of the magnetic portion is set within a range of 5% to 15% in mass percentage;
a moving member for reciprocating together with the plunger to control a flow rate of fluid flowing through the fluid paths; and
a biasing means for biasing the moving member in a direction opposite to a direction in which the plunger is attracted by the attracting portion.
