1. An electronic apparatus comprising:
a housing formed as one piece with a first boss member; and
a second boss member formed as a separate piece from said first boss member, and mounted on said housing to form a boss portion.
2. An electronic apparatus comprising:
a housing having a projecting portion formed as one piece therewith; and
a boss member to be mounted on said projecting portion to form a boss portion.
3. An electronic apparatus according to claim 2,
wherein said second boss member is fixed to said projecting portion by screw engagement.
4. An electronic apparatus according to claim 2,
wherein a height of projection of said projecting portions from said housing is within a range of approximately 1.5-2.0 times an external diameter of the projecting portions.
5. An electronic apparatus according to claim 1, wherein said housing is formed of a magnesium alloy, and said boss members are formed of metal.
6. A method of manufacturing an electronic apparatus having a housing with a boss portion, comprising the steps of:
a housing forming step for forming the housing introducing molten metal into a mold device, the housing having a projecting portion at a location where said boss portion is to be formed, and the housing constituting portions other than the boss portion of said housing; and
a boss portion forming step for forming the boss portion by fixedly engaging a boss member, which is to constitute the boss portion, with said projecting portion.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A stabbing basket for a rig and for supporting a worker during running operations, comprising:
a frame member for mounting the stabbing basket to the rig;
a platform to support the worker;
a carriage to slidably mount the platform to the frame member;
vertical power means for moving the carriage vertically with respect to the frame member;
an articulating boom, interconnecting the platform with the carriage and to facilitate horizontal and vertical movement of the platform relative to the carriage and frame member, said articulating boom comprising a first segment and a second segment, the first segment and second segment each having a distal end and a proximate end, the proximate end of the first segment being pivotally connected to the carriage, the distal end of the first segment being pivotally connected to the proximate end of the second segment, and the distal end of the second segment being pivotally connected to the platform; and
at least one pivoting actuator and a second pivoting actuator positioned between the distal end of the first segment and the proximate end of the second segment, wherein said at least one pivoting actuator and said second pivoting actuator are connected in a substantially mutually perpendicular arrangement.
2. The stabbing basket of claim 1 wherein the at least one pivoting actuator is a rotary hydraulic actuator.
3. The stabbing basket of claim 1 wherein the at least one pivoting actuator and the second pivoting actuator are both rotary hydraulic actuators.
4. The stabbing basket of claim 1 further comprising:
a third pivoting actuator; and
a fourth pivoting actuator;
wherein said third and fourth pivoting actuators connect the articulating boom to the carriage and are arranged in a substantially mutually perpendicular manner.
5. The stabbing basket of claim 4 wherein the at least one pivoting actuator, the second pivoting actuator, the third pivoting actuator and the fourth pivoting actuator are all rotary hydraulic actuators.
6. The stabbing basket of claim 1 wherein the vertical power means comprises:
a leadscrew mounted within the frame member in a substantially vertical plane substantially parallel with said frame member;
a motor to drive the leadscrew; and
a nut member mounted on the carriage to receive the leadscrew.
7. A stabbing basket for a rig and for supporting a worker during running operations, comprising:
a platform to support the worker;
an articulating boom, interconnecting the platform with the rig and to facilitate horizontal and vertical movement of the platform relative to the rig, said articulating boom comprising a first segment and a second segment, the first segment and second segment each having a distal end and a proximate end, the proximate end of the first segment being pivotally connected to the rig, the distal end of the first segment being pivotally connected to the proximate end of the second segment, and the distal end of the second segment being pivotally connected to the platform; and
at least one pivoting actuator and a second pivoting actuator positioned between the distal end of the first segment and the proximate end of the second segment, wherein said at least one pivoting actuator and said second pivoting actuator are connected in a substantially mutually perpendicular arrangement.
8. The stabbing basket of claim 7 wherein the at least one pivoting actuator is a rotary hydraulic actuator.
9. The stabbing basket of claim 7 wherein the at least one pivoting actuator and the second pivoting actuator are both rotary hydraulic actuators.
10. The stabbing basket of claim 7 further comprising:
a third pivoting actuator; and
a fourth pivoting actuator;
wherein said third and fourth pivoting actuators connect the articulating boom to the carriage and are arranged in a substantially mutually perpendicular manner.
11. The stabbing basket of claim 10 wherein the at least one pivoting actuator, the second pivoting actuator, the third pivoting actuator and the fourth pivoting actuator are all rotary hydraulic actuators.
