Title: Method of preventing galloping of multiconductor transmission line
IPC: H02G7/12
Filed: 1992-05-23
Abstract: PURPOSE:To prevent the galloping by attaching a snow adhesion restrainer to the conductor on the side of being caught by the loose catch of a loose spacer. CONSTITUTION:Generally, since spacers are attached at intervals of 30-50m, if loose spacers 2 are attached all at once in the longitudinal direction of a transmission line, the conductor 1A on the side of a fixing and catching part 3 does not need the attachment of a snow adhesion restrainer, but the conductor 1B on the side of a loose catch part 4 gets in the same condition as the condition that a single conductor is stretched across, so there is possibility of excessive snowing and icing occurring. Therefore, excessive snowing and icing is prevented by attaching a snow adhesion restrainer (for example, a snow ring) 5 to the conductor 1B on the side of being caught by the loose catch 4. If the snowing and icing is small without becoming excessive, it does not cause large damage even if it is subjected to wind. Hereby, galloping can be prevented.

Filed: 1987-06-23
Abstract: PURPOSE:To simply and suitably perform an outer lead bonding without forming the outer lead and the die pad of a lead frame by bonding it by a bonding jig while a carrier tape is being supported from its lower side. CONSTITUTION:When the outer leads of a semiconductor device are bonded by a TAB system, a protrusion 10 is protruded on a stage 1 as a support for supporting a carrier tape 3 from its lower side. When a bonding jig 5 is moved down in this state, an outer lead 8a is brought into pressure contact with the inner lead 4a of a lead frame 4 while the lead 3a is being bent by pressing, and both members are bonded by pressure heating.

Title: Magnetic head and its production
Inventor: RIYOUNO MASARU
IPC: G11B5/187
Filed: 1988-06-23
Abstract: PURPOSE:To eliminate a defect that causes the variance of the track width by exposing a 1st soft magnetic metal over a sloping surface part having an approximately trapezoidal section together with a 2nd soft magnetic metal formed on an upper surface part and the sloping surface respectively and using the 2nd soft magnetic metal to secure the magnetical connection between both 1st soft magnetic metals set opposite to each other. CONSTITUTION:The 1st soft magnetic metals 2 held between the head cores 1 set at one side are joined to a 2nd soft magnetic metal 9 set at a sloping surface 8b having an approximately trapezoidal section. This metal 9 is magnetically connected to another metal 2 set opposite to the first one at an upper surface part 8a having an approximately trapezoidal section. Thus a gap 11 is formed. Then the metal 9 is joined to the metal 2 at the part 8b and a desired magnetic circuit is formed. Therefore the track width of the gap 11 is decided by a part where both parts 8a are opposite to each other at the part having an approximately trapezoidal section. Thus it is possible to avoid such a defect that causes the track width variance due to a fact that both metals 2 are not opposite to each other.

Filed: 1995-06-23
Abstract: PURPOSE: To provide a semiconductor device which does not stop a system of an apparatus mounting the device, etc., by preventing a plurality of installed output leads from being fused. CONSTITUTION: Output pads 13a, 13b, 13c of power MOSFET 12a, 12b, 12c of an output part 11 are connected with an output terminal 15 by using bonding wires 16a, 16b, 16c. The values of currents flowing through the bonding wires 16a, 16b, 16c are limited smaller than or equal to the allowable current values, by excess current detection protective circuits 17a, 17b, 17c in an excess current limiting part. When disconnection, imperfect connection, etc., exist in the bonding wires 16a, 16b, 16c, the values of currents flowing through other normal wires increase. The increase of current values of normal wires is detected by the excess current limiting part, and current values are limited smaller than or equal to the allowable current values. Hence currents exceeding the allowable values do not flow through the wires, so that their fusing can be prevented.

Abstract: PURPOSE:To prevent lowering of flame temp. in a blast furnace and to improve the productivity and coke ratio under stable furnace condition by blowing only decomposed product after beforehand thermal-decomposing pulverized coal at the time of blowing the pulverized coal from a tuyere part in the blast furnace. CONSTITUTION:At the time of blowing the pulverized coal from the tuyere as partial alternative material to an expensive bulky coke in the blast furnace operation, the coal in low cost is pulverized with coal pulverizer 3 and the pulverized coal is thermal decomposed into coal gas, tar and char with a thermal decomposing device 4, and the coal gas and the tar are separately utilized, and only the char 7 is blown from the tuyere in the blast furnace 6 together with hot blast from a hot stove 2.
