摘要:
The present invention has for its purpose to provide a technique capable of reducing planar dimension of the semiconductor device. An input/output circuit is formed over the semiconductor substrate, a grounding wiring and a power supply wiring pass over the input/output circuit, and a conductive layer for a bonding pad is formed thereover. The input/output circuit is formed of MISFET elements in the nMISFET forming region and the pMISFET forming region, resistance elements in the resistance element forming regions and diode elements in the diode element forming regions functioning as protective elements. A wiring connected to the protective elements and positioned under the grounding wiring and the power supply wiring is pulled out in a pulling-out region between the nMISFET forming region and the pMISFET forming region and between the grounding wiring and the power supply wiring to be connected to the conductive layer.

A method of preparing a thermoelectric material includes the following steps. A thermoelectric raw material can be filled into a cavity of a first mold so that the thermoelectric raw material filled in the cavity has first and second dimensions. The first dimension can be defined in a first direction. The second dimension can be defined in a second direction. The second direction can be perpendicular to the first direction. The first dimension can be equal to or greater than the second dimension. The thermoelectric raw material filled in the cavity can be cooled in a uniaxial direction that is parallel to the second direction at a cooling rate of at least 600° C./min.

A thermoelectric module comprises a plurality of thermoelectric elements which are arranged between a pair of substrates having electrode patterns and which are bonded with the electrode patterns via solder in which at least one dispersion phase is dispersed into a matrix phase, wherein the melting temperature of the dispersion phase is higher than that of the matrix phase (i.e., 240° C. or over), and the dispersion phase comprises fine particles whose average diameter is 5 μm or less. The solder is constituted by an alloy so as to realize a volume ratio of 40% or less, wherein it is composed of a Bi—Cu—X alloy or a Bi—Zn—X alloy (where ‘X’ represents at least one element selected in advance). Preferably, the solder is constituted by powder containing fine particles whose average diameter is 100 μm or less or thin plates whose average thickness is 500 μm or less.

It is an object of the invention to provide a sensor which is highly reliable, and a method or producing a sensor which is highly reliable, and which can be easily produced. A method of producing a sensor in which bending of a heater and the like hardly occur is provided.In the invention, an oxygen sensor (1) has: an oxygen sensor element (2); a metal shell (3); first and second sensor terminal metal parts (11), (12); a heater (15); heater terminal metal parts (16), (17); a metal outer tube (21); and a separator (31) which is housed inside the metal outer tube (21), in which the terminal metal part (11) and the like and the heater (15) are held, and which provides insulation between the terminal metal part (11) and the like. An outer-tube butting face (34a) is formed in a flange portion (34) of the separator (31). In the metal outer tube (21), a flange butting face (24b) which butts against the outer-tube butting face (34a) is formed. Both of the outer-tube butting face (34a) and the flange butting face (24b) form an inclined face which is more radially outward positioned as further advancing toward the tip end. The separator (31) is pressed toward the rear end. The pressing is conducted by deforming the metal outer tube (21), and deforming a pressing metal part (41) which is placed around a tip end side portion (33) of the separator (31).

The present invention provides a metal thin film type magnetic recording medium having improved tracking stability and friction stability, by improving the lubricating layer in consideration of the state of forming the lubricating layer in view of the distribution of the lubricant. The magnetic recording medium according to the present invention at least has, in turn, a metal magnetic layer, a protective layer and a lubricating layer on one surface of a nonmagnetic base. The covering ratio of a surface of the lubricating layer with the lubricant is 65-75%. The lubricating layer is produced by applying a mixture of solvents containing at least three solvents selected from three groups, that is from at least one from group (1): ketone solvents having a boiling point of 40-130° C., at least one from group (2): aliphatic hydrocarbon solvents having 4 carbons-10 carbons, and at least one from group (3) alcoholic solvents having equal or less than 6 carbons, the mixture ratio of these solvents of respective groups being preferably selected to be: (1) ketone solvents 5-20% wt.; (2) aliphatic hydrocarbon solvents 10-40% wt.; and (3) alcoholic solvents 40-80% wt.
