Abstract:
PROBLEM TO BE SOLVED: To provide a collision cooling device which is in contact with a microprocessor. SOLUTION: This invention includes a cooling device comprising parallel return paths and having a lot of collision injection ports closely arranged with spaces adjacent to a collision gap 42. This invention also includes a method for, by using branching hierarchy manifolds alternatively engaged, supplying a cooling agent flow to the collision injection ports with less pressure drop as much as possible. Further, a surface extension structure extending to the collision gap 42 forms a U-shaped micro channel between a single collision injection port and a single exit. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a probe and a data storage device, requiring less power consumption. SOLUTION: The data storage device includes a storage medium for storing data in a form of marks, and at least one probe for scanning this storage medium, and the storage medium can be included in the substrate. The probe contains a cantilever including a terminal, where this terminal functions as an electrical contact to mechanically be fixed on a probe retention structure, which can be a common frame of the data storage device during probe operation. The probe also contains a support structure, to which it mechanically connects the terminal directly or via a hinge. This support structure extends so as to separate from the terminal. The end section having a nano-scaled vertex is provided. A beam structure, which contains a heat resistor, is installed at the end section of the support structure. This beam structure is thinner than the area of the support structure, directly contacting the beam structure in at least the direction parallel to the shaft of the end section.

Abstract:
Apparatus for reducing sensitivity of an article to mechanical shock comprises a frame; first and second planar masses mounted in the frame for bi-directional movement relative to the frame along a first axis of displacement; a first lever pivotable about a first fulcrum secured to the frame; the lever having one end connected to the first mass and the other end connected to the second mass, and the fulcrum being disposed between the ends of the lever; whereby the torque exerted about the fulcrum by the first mass is countered by the torque exerted about the fulcrum by the second mass in response to a mechanical shock applied to the frame along the axis of displacement such that an article carried by the first mass in use has reduced sensitivity to the shock.
Abstract:
A microsystem switch (1, 20, 25, 30, 33) has a support (2) defining a recess (3), and a flexible bridge (6) is mounted on the support (2) bridging the recess (3). The bridge (6) is shaped so as to hold selectively a concave support stable state, in which the bridge bulges out of the recess (3). The switch includes an actuator (8, 9; 26, 27) for effecting flexing of the bridge (6) between the stable states, and a switching element (7, 31, 34) is mounted on the bridge (6) such that movement of the bridge between the stable states moves the switching element between an on position and an off position. According to another design, a microsystem switch (40, 55) has a support (41) defining a recess (42), and an elongate torsion member (44) is mounted on the support (41) bridging the recess (42). A flexible bridge (43, 56) is mounted on the support (41) bridging the recess (42) in a direction substantially perpendicular to the torsion member (44). The bridge (43, 56) is connected to the torsion member (44) at the cross-point thereof so that a first section of the bridge extends between the cross-point and one side of the recess (42) and a second section of the bridge extends between the cross-point and the opposite side of the recess (42). The bridge (43, 56) is shaped so as to hold selectively a first stable state, in which the first section of the bridge bulges into the recess and the second section of the bridge bulges out of the recess, and a second stable state in which this configuration is reversed. A switching element (45) is mounted at the cross-point of the bridge (43, 56) and torsion member (44), and an actuator (46a, 46b; 58a, 58b) is again provided for effecting flexing of the bridge (43, 56) between the stable states. Here, movement of the bridge (43, 56) between the stable states effects twisting of the torsion member (44) and rotation of the switching element (45) between an on position and an off position. Switching devices incorporating these switches, and switching apparatus comprising arrays of such switching devices, are also provided.

The integrated circuit stack (1) is cooled using a cooling fluid (10) pumped through the cooling layer (3). The invention further relates to a method for optimizing a configuration of such an integrated circuit stack (1).
Abstract:
A write head 108 comprises a yoke 110 having at least a first and a second gap 112, 114 and a coil 116 for producing a magnetic field at each gap. The coil comprises a plurality of windings 118, 120 which are arranged to produce the same magnetic field strength at each gap and/or along each gap by use of a proximity effect between the windings and a respective gap. Gaps may be arranged symmetrically about a first line 214 and the windings 209, 209, 213, 213 can be arranged in a pattern symmetrically about a second line 212 where the first and second lines are offset from each other. The distance between neighboring winding portions may vary and the windings may be non-parallel to each other. The write head can be used for writing servo patterns on magnetic tape.
Abstract:
A tape head 1 is adapted for reading and/or writing to a magnetic tape and has a tape-bearing surface comprising a transducer area 30 and a cavity 51, 52 adjacent to the transducer area. The transducer area comprises at least one transducer that is a read and/or write element. The cavity is open on the tape-bearing surface, and extends parallel to the transducer area, transversally to a longitudinal direction of circulation of the tape, such that an opening of the cavity faces the tape, in operation. The cavity is further dimensioned and arranged with respect to the transducer area to create sub-ambient pressure upon circulation of the tape. Air bleed slots may connect to the cavity and a lateral edge surface or another cavity. The transducer area may form a crenellated structure so that the transducers protrude. The tape head may have a bevelled 72b or rounded edge.
Abstract:
A write head is provided for writing a servo pattern to a magnetic tape storage medium. The write head comprises at least a first write gap A and a second write gap B, the gaps being separately energizable. The second write gap comprises at least a first section a and a second section b. Energization of the second write gap causes a magnetic flux across the first section insufficient for changing a magnetization of a track and the second section 10 is designed such that energization causes a magnetic flux across the second section sufficient for magnetizing a track of the magnetic tape storage medium TP. The gaps may be inclined or perpendicular to a motion direction of the tape. The head may have a third write gap separately energizable to the first and second gaps where the third gap also has first and second sections. A method of writing a servo band comprises moving a servo band across at least first and second write gaps.
