Title: Thermal fuse
Inventor: SUNAOKA YOSHIKI
IPC: H01H37/76
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To correspond to automation in soldering and to ensure response to the ambient temperature by preventing fusing of a fusible alloy, and by forming a lead wire by plating the periphery of a nickel wire, a brass wire, a copper alloy wire, an oxygen free copper wire, a phosphorus bronze wire or a copper covering steel wire with copper, and with tin, nickel or the like. SOLUTION: The periphery of, for example, a nickel wire 4a used as a core is thinly plated with copper 4b for excellent conductivity, and the outer periphery of the nickel wire 4a is thinly plated with tin 4c to smoothly perform soldering so that a lead wire 4 is formed. As another example, the periphery of a brass wire, a copper alloy wire, an oxygen free copper wire, a copper covered steel wire or the like used as the core is plated with copper, the periphery of which is plated with tin, nickel or the like to form the lead wire 4. This decreases thermal conductivity, and can avoid that heat is transmitted to a fusible alloy 3 through the lead wire 4 so that the fusible alloy 3 is fused.

Abstract: PROBLEM TO BE SOLVED: To improve the cooling efficiency of an equipment in a panel by forming a wind tunnel that reaches from space in an enclosure to an exhaust port and arranging a heat sink for cooling the equipment in the panel close to the wall surface of each wind tunnel in the wind tunnel. SOLUTION: A fin 23 of a second heat sink 23 for cooling equipment in a panel with the largest calorific value is arranged in a first wind tunnel that is covered with a central mounting plate 21, a unit side plate 22, and a rear surface plate 28. Since the first wind tunnel is continuous with a fan 29 and an exhaust port 11A for generating an air flow, a channel where fresh air for cooling the equipment in the panel is unloaded must pass through the wind tunnel, thus generating a high-wind speed air flow inside a fin 23b and satisfactorily cooling a heat generation semiconductor element 24 that has the largest calorific value and hence needs to be cooled the most. The air flow exiting here is deflected in a plenum chamber 105 as a second wind tunnel, is sucked by a fan 29, reaches an exhaust chamber 106 as a third wind tunnel, and is unloaded.

Title: Semiconductor wafer cleaning device and manufacture of semiconductor wafer
Inventor: KAIDO YOSHIE
IPC: B08B1/04
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent particles from a use finished cleaning liquid from readhering on the surfaces of a wafer in cleaning of both surfaces of the wafer. SOLUTION: In a wafer cleaning device 1, a wafer W is pinched by cleaning rollers 2 and both surfaces of the wafer W are cleaned by rotating these rollers 2. By installing these rollers 2 obliquely to the horizontal plane, the abutting parts of the surfaces of the wafer W on these rollers are put in an oblique state. Thereby, as an unnecessary cleaning liquid flows down without stagnating in these abutting abutting parts, particles do never readhere on the surfaces of the wafer W from this unnecessary cleaning liquid. Accordingly, it becomes possible to provide the high-quality cleaned surfaces of the wafer as compared with the cleaned surfaces of the conventional wafer.

Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To provide an electrode for wire bonding for obtaining prescribed strength at a junction with a wire, and a method for manufacturing the electrode for wire bonding. SOLUTION: An electrode 1 for wire bonding is formed on an N-type AlGaAs epitaxial layer 11 and is constituted of an AuGe-Ni-Au alloy layer 17, Ti layer 15, and Au layer 16. After the Ti layer and the Au layer 16 are formed, since these are not subjected to heat treatment, sufficient wire bond strength can be obtained, while a base metal, that is, Ta, As, Ni, Ge or the like is not pile up on the surface of the Au layer. Also, since the Ti layer 15 functions as an etching stopper, etching of each Au layer and AuGe-Ni-Au alloy layer can be carried out independently. That is, an optimal etching liquid can be used for each layer, and side etching can be reduced to a minimum.

Title: Method and device for verifying rounding of waveform
Inventor: YAMAMOTO MIYUKI
IPC: G06F17/50
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To establish a technology for verifying the rightness/non-rightness of a relation between a time signal and the rounding of waveform, which delay relative to the rounding of waveform. SOLUTION: The rounding of waveform of the arrival point of a time signal transmitted between two places on a circuit is obtained by calculation. The minimum pulse width of an ideal time signal, which does not consider the rounding of waveform of the arriving point, is regulated by considering the delay of the signal and the sizes of waveform and minimum pulse width are compared. Correct data is recognized to be latched at the arbitrary place in the circuit regardless of delay. If not, the circuit at the place can be corrected so that the rounding of waveform can be permitted. It is desirable that jitter is considered in delay.
