Abstract: PURPOSE:To prevent tungsten from coming off viaholes at an input/output pad, by forming a given horizontal space between end parts of upper and lower viaholes having larger inside diameters than the bonding part. CONSTITUTION:A first aluminum conductor 21 is coated with an interlayer insulating film 20, in which a lower viahole 3 of large diameter is provided together with a tungsten sidewall 24 at an end part thereof. A second aluminum conductor 22 and an upper viahole 4 having a smaller inside diameter than the lower viahole 3 are formed thereon. Then, a tungsten sidewall 25 is formed at an end part of the upper viahole 4, and a third aluminum conductor 23 is formed thereon. In this way, the tungsten sidewalls 24 and 25 are placed on a given horizontal space in between, and the upper tungsten sidewall 25 is formed in a flat region of the second aluminum conductor 22. Consequently, the tungsten can be prevented from coming off.

Title: Semiconductor device
Inventor: YANAGISAWA HIROTAKA
IPC: H05K3/34
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To keep a printed board coming into close contact with the leads of a semiconductor chip, even if the board is warped so as to enhance a semiconductor device in product yield by a method, wherein a laminate composed of, at least, two laminated different materials differing from each other in linear expansion coefficient with respect to a mounting surface is provided to the tip of each lead. SOLUTION: A semiconductor device 30 is equipped with a package 31, where a semiconductor chip is housed and leads 32 connected to the terminals of the semiconductor chip respectively. The lead 32 is of laminated structure (laminate part) composed of a copper layer 32 and iron-nickel alloy layer 34. Copper is larger in linear expansion coefficient than iron-nickel alloy. Therefore, when the copper layer 33 and the iron-nickel alloy layer 34 are laminated and heated, the copper layer 33 expands more than the iron-nickel alloy layer 34, so that the laminate composed of the copper layer 33 and the iron-nickel alloy layer 34 are warped.  On the other hand, the lead 32 of the semiconductor device 30 is warped, so that the terminals of a semiconductor chip are kept, coming into close contact with the leads 32, and a semiconductor device of this constitution is free from defective soldering and enhanced in product yield.

Title: Metal bellows type accumulator
Inventor: ISOBE HIROYUKI
IPC: F15B1/08
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the damage to a bellows by providing a stopper for preventing the shrinking of the bellows to a size smaller than a minimum stroke in the metal bellows. SOLUTION: A stopper 16 is formed to be cylindrical, both ends thereof being opened, and one end thereof is attached to the inner surface of the gas injection side end plate 6a of a shell 6. For its material, any may be used as long as it has a strength for supporting a bellows 8 when the high pressure of hydraulic oil 15 is applied after injected gas 7 is leaked from the bellows 8, a length L is set longer than a minimum stroke for compressing the bellows 8 and leading to damage and an outer diameter R is set a little smaller than the inner diameter of the bellows 8.  If the leakage of the injected gas 7 occurs because of the damage of a gas injection spigot 12 or a sealing 13, the bellows 8 is compressed by the pressure of the hydraulic oil 15, but since the bellows 8 is supported from the inside by the stopper 16 and the bellows 8 is never compressed to a size smaller than a minimum stroke, leakage in a radial direction is prevented and the damaging of the bellows 8 is prevented.

Title: Cueing system for error in number of used byte for magnetic disc device
Inventor: KAWAMOTO MASAKAZU
IPC: G11B20/12
Filed: 1981-05-29
Abstract: PURPOSE:To increase the efficiency of use of a magnetic device, by neglecting errors out of errors in number of used bytes possible for the continuity of processing through the adoption of a cueing circuit. CONSTITUTION:The number of used bytes is read with a used byte counter and check circuit 10, and in case of an error, an error signal is given to an FF17 to obtain ''1'' for the output and an AND circuit 18 keeps the signal until a format write signal comes. When the next record is read and the number of used bytes is correct, since the FF17 is reset with a clock of a count read signal and a correct signal is inputed to the FF17, the output of the FF17 is 0. Only when the number of used bytes is in error and the format write signal comes, an error signal is outputted from the AND circuit 18 and given to the disc controller 13. Thus, the processing of other tags can be processed in other cases.
