A semiconductor device in which the lifetime of mounted components can be prolonged. A cooling system for controlling the temperature of a refrigerant through a heating section and a radiator is provided. The semiconductor device is connected to the cooling system and is cooled. A variation width (ΔT1) of temperature controlled by the cooling system through the heating section and the radiator is smaller than a temperature variation (ΔT2) of the refrigerant caused by variations in operating conditions of the semiconductor device (ΔT1≦ΔT2).

To provide a low cost mounting structure of an electronic component and to increase the reliability of the conductive connection between a bump electrode and a terminal formed on a substrate, in the mounting structure of the electronic component, the bump electrode includes a core composed of an inner resin and a conductive film covering the surface of the core. The bump electrode is brought into conductive contact with the terminal directly and is elastically deformed to make contact with the face of the substrate in a planar manner. A sealing resin is filled in around the conductive contact portion between the bump electrode and the terminal to hold the bump electrode and the terminal.
摘要:
A machining feed rate for machining a workpiece portion to be machined by a machining tool based upon a machining program is set by reading a data of the workpiece portion, by sectionalizing the workpiece portion in an area corresponding to a workpiece shape of the workpiece portion, and by determining a shape change point based upon a workpiece shape of the workpiece portion. The machining feed rate is set for each area and for each shape change point with reference to a predetermined parameter corresponding to an attribute of the each sectionalized area and corresponding to an attribute of the each determined shape change point.

In a data recovery processing, the conventional overhead, primarily, latency due to a rotational recording media is removed. Secondary, in a signal processing or in a recording and reproducing apparatus, reliability of data reproduction is improved by repeatedly processing data. These processing are achieved that input signal, i.e., raw analog signal read from the recording media is digitized to be stored in a secondary storage such as a memory or a FIFO memory. The apparatus includes a signal processing circuit to repeatedly process the stored digital signal in the secondary storage. When detecting data, operation of the circuit is efficiently controlled by a change over detector parameters, in which characteristics for the detecting performance. Resultantly, data recovery processing speed is increased and reliability of data reproduced is improved.
