摘要:
The present invention provides a capacitive liquid state sensor configured to release a pressure in an intervening gap by providing slits to an outer tubular electrode while inhibiting decrease in strength caused by forming of the slits. The outer tubular electrode 20 disposed with a predetermined distance from an inner electrode 20 is formed with a plurality of slits 14, 15 and 16 along a generator (indicated by one-dot chain line A) extending from a front end portion 11 to a rear end portion 12. Between the slits 14, 15 and 16 are positioned intermediate no-slit formed areas 17 and 18. Circulation of liquid between the inside and the outside of the outer tubular electrode 10 and in the axial direction of the same electrode 10 is attained through the slits 14, 15 and 16, so that a pressure accompanied by volumetric expansion of liquid at the time of freezing and existing in the intervening space can be released to the outside. Further, by the provision of the intermediate no-slit formed areas 17 and 18, the outer tubular electrode 10 can maintain a good strength so that deformation of the outer tubular electrode 10 can be prevented effectively.

An end portion of a pin 2 rotatably supporting a rolling body 1 is fitted in a pin-receiving hole 4 formed in an annular side plate 3. The pin-receiving hole 4 has interference in a range from 5 to 40 μm between itself and the outer diameter of the pin 2. The end portion of the pin 2 pressed in the pin-receiving hole 4 with 5-40 μm interference is welded to the annular side plate 3.

This invention provides a stacked ceramic body that prevents reaction between components of dielectric layers and components of electrode layers of an unsintered stacked body during sintering and in which both components do not easily form a liquid phase, and a production method of such a stacked ceramic body. A print portion 13 is formed on a green sheet 1, 12 containing lead by use of an electrode paste consisting of copper oxide as its main component. A desired number of print sheets 10 are stacked to give an unsintered stacked body 15. Degreasing is conducted in an atmosphere to degrease organic components. The print portion 13 is subjected to reducing treatment in a reducing atmosphere containing hydrogen and is converted to a print portion 13 containing copper as its main component. The unsintered stacked body 15 is sintered in a reducing atmosphere. Dielectric layers containing lead and electrode layers for applying a voltage to the dielectric layers are alternately stacked, and an oxidation portion containing copper is formed in the proximity of a surface of the electrode layer. A thickness of the oxidation portion in a stacking direction is 0.5 to 2 μm and a copper content in the oxidation portion is 1 to 30 wt %.
