摘要:
A coil-type electronic component has a coil inside or on the surface of its base material wherein the base material in the coil-type electronic component is constituted by a group of grains of a soft magnetic alloy containing iron, silicon and other element that oxidizes more easily than iron; the surface of each soft magnetic alloy grain has an oxide layer formed on its surface as a result of oxidization of the grain; this oxide layer contains the other element that oxidizes more easily than iron by a quantity larger than that in the soft magnetic alloy grain; and grains are bonded with one another via this oxide layer. The coil-type electronic component can be produced at low cost and combines high magnetic permeability with high saturation magnetic flux density.

摘要:
A screw compressor is equipped with a manually operated internal volume ratio adjusting slide valve and capacity adjusting slide valve. The compressor is simple in construction, can be produced with low cost, can accommodate decrease in suction pressure, for example, in an aged gas well, and can be operated without an electric power source for controlling the operation thereof. Also a combined screw compressor unit consisting of a plurality of screw compressors for producing high discharge pressure is provided which can accommodate high suction pressure in order not to overload the higher pressure compressor or compressors with the efficiency of the unit kept as high as possible by including at least a screw compressor according to the present invention in the unit.
摘要:
The present invention provides a pressure sensor module which is capable of restraining application of a pressure of increased magnitude to a connector, reducing the number of parts therefor and compacting a structure thereof. A connector body (3a) is provided on a base section thereof with a flange (3g). An annular support (4) which is made of a material hard to be deformed under a high pressure as compared with the connector body (3a) is provided with an annular engagement recess (4b). The annular support (4) is fitted on the connector body (3a) to engage the flange (3g) with the annular engagement recess (4b). The annular support (4) is contacted on one end surface (4a) thereof with a pressure non-sensing side insulating substrate (5a) of a pressure sensing element (5) outside the base section of the connector body (3a). A housing (7) includes a cylindrical engagement section (7g1), which is curled so as to surround an outer edge of an end surface (4c) of the annular support (4), to thereby accomplish engagement between the housing (7) and the annular support (4).
