摘要:
A lip seal device for a rotary shaft in which an annular metal casing has a cross section almost in a box shape except for a radially and axially inward gap. A seal member fills most of the box. A spacer and a radially outer portion of a lip seal, contacting the rotary shaft at its inner portion, are sandwiched in the gap between a radial wall of the casing on one side and the seal member and an end of the inner axial wall of the casing.

A liquid jet recording head is provided with a liquid discharging portion having an orifice for discharging liquid and forming flying liquid droplets, and a liquid flow path communicating with the orifice and having as a part of the construction thereof a heat-acting portion in which heat energy generated in a heat-generating portion for forming the liquid droplets acts on the liquid, and an electro-thermal converting element electrically connected to a heat-generating resistive material layer provided on a base plate, the electro-thermal converting element having at least a pair of opposed electrode wiring portions provided on the heat-generating resistance material layer, the heat-generating portion being formed between the electrode wiring portions. The width of the heat-generating resistive material layer in at least the part of the heat-generating resistive material layer in the area in which the electrode wiring portions are layered is greater than the width of the electrode wiring portions.
摘要:
The invention relates to a surface mount type electronic component to be mounted on a printed circuit board or a hybrid IC (HIC) and provides a low-cost electronic component which is reliable in terms of heat resistance and pressure resistance. An inductor as the electronic component has a general outline in the form of a rectangular parallelepiped, provided by forming a lead-out electrode having a multi-layer structure on a substrate and forming a protective layer for protecting the lead-out electrode using thin film forming techniques. The lead-out electrode includes a first electrode which is electrically connected to a coil conductor and which has an exposed part exposed on an outer surface and a second electrode which has an exposed part exposed on the outer surface to extend an electrode width different from an electrode width of the first electrode and which is formed directly above the first electrode and electrically connected to the first electrode.
