An oil filter for preliminarily confirming a correct assembling of a valve body to a holder and for preventing the valve body from being abnormally assembled. A valve seatis welded to a capcovering a filter element. A claw portion for a valve bodyis formed on the valve body, and an engagement portion for the valve bodyto be engaged with the claw portion for the valve bodyis formed on a holderassembled with the inner peripheral side of the filter element. In addition, a spring memberis fitted between the valve bodyand a spring receiving portionprovided for the holder. By the engagement of the claw portion for the valve bodywith the engagement portion for the valve body, the valve bodyis assembled with the holder

Oil filter and method of manufacturing the oil filter

Method and apparatus for measuring a surface temperature of an object body, by calculating a temperature at each picture element of an image of the object body, on the basis of a radiant intensity ratio at each pair of corresponding picture elements of a first and a second image which are obtained with respective radiations having respective first and second wavelengths which are selected from a light emitted from the surface of the body, by a first filter which permits transmission therethrough a radiation having the first wavelength which is selected according to a radiant intensity curve corresponding to a wavelength of a black body at a lower limit of a temperature measurement range, and which is within a high radiant intensity range in which the radiant intensity is higher than a radiant intensity at a normal room temperature, and a second filter which permits transmission therethrough a radiation having the second wavelength which is selected within the high radiant intensity range, such that the second wavelength is different from the first wavelength by a predetermined difference which is not larger than &frac13; of the first wavelength and which is not smaller than a sum of half widths of the first and second wavelengths.

An oil mist filter capable of removing oil mist and separating liquids of low viscosity. A filter section in the oil mist filter is of two-stage construction. The filter section includes a filter body disposed in the upper stage for arresting oil mist and a support body disposed in the lower stage to support the filter body and capable of separating gas fuel. A space is defined below the filter body. When passing through the filter body the oil mist in the gas fuel is arrested by the filter body. The liquid content in the gas fuel is collected below the filter body in the upper stage, and then moves under its own weight along the support body in the lower stage until it is collected in the space. The gas fuel having its liquid content removed is passed through the support body and fed to the engine.

A method of measuring a temperature of an object body in an electric furnace, based on an intensity of a radiant energy emitted from the object body, the electric furnace being provided with an electric heater operable by application of a drive voltage thereto to heat the object body, the method comprising: a radiant-energy detecting step of detecting an intensity of a radiant energy emitted from the object body; a stray-light noise eliminating step of determining as a noise an intensity of a radiant energy of a stray light which is emitted from an inner wall surface of the electric furnace toward the object body and reflected by a surface of the object body, according to a predetermined relationship between the intensity of the radiant energy of the stray light and the drive voltage applied to the electric heater and based on an actually applied value of the drive voltage, and subtracting the intensity of the radiant energy of the stray light determined as the noise, from the detected intensity of the radiant energy emitted from the object body; and a temperature calculating step of calculating a temperature of the object body, based on the intensity of the radiant energy emitted from the object body from which the noise has been removed in the stray-light noise eliminating step. Also disclosed is an apparatus for practicing the method, which may include a shielding device disposed between the furnace walls and the object body.

A spring is crimpingly fixed to an element holding plate of the fluid filter. Since the spring is crimpingly fixed to the element holding plate a material having a high elastic limit can be freely selected for the spring At the assembling time, the spring can be prevented from yielding to be elastically deformed, even when the size between the upper end of the element and the crest of the filter case fluctuates. As a result, it is possible to provide a fluid filter which requires no high sizing accuracy of the individual parts composing the fluid filter at the assembling time so that it can be easily assembled.

Fluid filter

To provide a separator for a battery with high safety and a method for producing the same in which the separator has a shutdown function and capability of preventing meltdown, complete melting and cracks when the battery performs unusually. This separator comprises a porous ceramic sheet having ceramic fibers bonded to each other at their intersection points and polyolefin and comprises micropores for impregnation of an electrolyte.
