Title: Trimming method for film resistor
Inventor: MIYAMOTO MASAKI
IPC: H01L27/01
Filed: 1991-11-12
Abstract: PURPOSE:To perform a trimming operation efficiently by a method wherein a film resistor for trimming use is formed to be trapezoidal or hook-shaped and a region where a current density is low is adjusted fine. CONSTITUTION:For example, when a trimming operation is performed by using a trapezoidal film resistor 12, the resistor is first adjusted coarsely by means of an L-shaped cut 13 for coarse adjustment use. Then, a cut 14 for fine adjustment use is executed from an oblique side in a region 12a where a current density is low. The resistor can be adjusted fine in a state that the change rate of a resistance value due to a trimming distance is low, and its fine adjustment is completed while an ordinary straight cut at a first working speed is used. Thereby, it is possible to efficiently perform the trimming operation whose working speed is fast and which can perform the high-accuracy fine adjustment.

Abstract: PURPOSE:To obtain a sufficient bonding strength without scrubbing by a method wherein a plate-shaped solder having a sufficiently smaller area than the area of the bonding surface of an optical semiconductor chip is provided. CONSTITUTION:A plate-shaped solder 2 having a sufficiently smaller area than the area of the bonding surface of a semiconductor chip 1 is placed between the semiconductor chip 1 and a bonding part. The semiconductor chip 1, the solder 2 and the bonding part are heated to a temperature higher than the melting point of the solder and a pressure is applied to the upper part of the semiconductor chip 1 to bond the semiconductor chip 1 to the bonding part with the solder 2. When the solder 2, for instance AuSn solder, is mashed by the optical semiconductor chip 1, as the area of the solder is small, the new solder which is not covered with an oxide film 3 bursts forth and the oxide film 3 is cut to pieces and the gap between the optical semiconductor chip 1 and the bonding part is filled with the new solder. With this constitution, a sufficient bonding strength can be obtained without scrubbing.

Title: Chip-like electronic component
Inventor: NERIMA HIROSHI
IPC: H01C1/14
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To secure mounting to a board and improve a heat dissipation effect, by bending electrode plates led out from lateral sides of a case toward an upper side and a lower side of the case, and thus exposing the electrode plates on the upper and lower sides of the case. SOLUTION: In a chip-like resistor 10, double electrode plates 31 and 33 led out from both left and right lateral sides of a case 20 are bent toward an upper side 21 and a lower side 23 of the case, thus exposing the electrode plates 31 and 33 on the upper and lower sides of the case 20. On the other hand, terminals 35 and 35 are projected from the surface of the front side of the case and bent downward. Thus, even when the chip-like resistor 10 is set upside down on a board, soldering between the board and the electrode plate 31 and 33 can be securely carried out since the electrode plates 31 and 33 are exposed on the upper and lower sides of the case 20. When the chip-like resistor 10 is soldered to the board in the normal attitude, the electrode plate 33 becomes a radiation board. In the reverse case, the electrode plate 31 performs heat dissipating action.

Abstract: PURPOSE:To enhance on-ice, on-snow running performance by arranging ribs having a specific width in the crown central region of tread, providing blocks or lug grooves in the shoulder parts on both sides, and thereby increasing the resistance against the contracting action in the tire circumferential direction. CONSTITUTION:In a tread pattern of tire, ribs 10 having a width W over 20% of the tread grounding width L are arranged zigzagged in the central region of the crown part, and blocks 4 are arranged in the shoulder parts on both sides.
