摘要:
A thermally conductive adhesive having: a thermosetting adhesive containing a curable component and a curing agent for the curable component, and a metal filler dispersed in the thermosetting adhesive uses a silver powder and a solder powder as the metal filler. The solder powder to be used has a melting temperature lower than the thermal curing temperature of the thermally conductive adhesive and produces a high-melting-point solder alloy having a melting point higher than the melting temperature of the solder powder when the solder powder is reacted with the silver powder under thermal curing conditions of the thermally conductive adhesive. A curing agent having flux activity to the metal filler is used as the curing agent.

The present invention utilizes self-heating of electronic components to improve a humidity sensing part with low environment resistance, such as a condensation problem and the like, and also to enhance the heat radiation efficiency of electronic components. The humidity sensing part is used in an intake tube of an automobile by integrating, for example, with a heating resister type mass air flow measurement device. A humidity sensing element is mounted on an electronic circuit board in a mass air flow measurement device with the temperature thereof starting to increase immediately after a sensor has been actuated. This urges the temperature of the humidity sensing element to start increasing (being heated) immediately after the sensor has been actuated. To urge the humidity sensing element to be further heated, a base plate is composed of two types of materials, resin and metal. A part of the base plate holding an area of the electronic circuit board generating a large quantity of heat is composed of the metal. A part of the base plate corresponding to the periphery of the humidity sensing part which is to be heated is composed of the resin.

The relative position of a test surface is sequentially changed from a reference position where a surface central axis is aligned with a measurement optical axis such that the measurement optical axis is sequentially moved to a plurality of annular regions obtained by dividing the test surface in a diametric direction. The test surface is rotated on a rotation axis whenever the relative position is changed. Measurement light composed of a plane wave is radiated to the rotating test surface, and a one-dimensional image sensor captures interference fringes at each of a plurality of rotational positions. The shape information of each annular region is calculated on the basis of the captured interference fringes at each rotational position, and the shape information is connected to calculate the shape information of the entire measurement region.

The light beam measurement apparatus comprises a beam splitter that divides a light beam emitted from a light source unit into two luminous fluxes, a semi-transmitting/reflecting surface that reflects part of one of the divided luminous fluxes back in the opposite direction to the direction of incidence as a sample luminous flux, and reflection-type reference light producing means that converts part of the luminous flux transmitted through the semi-transmitting/reflecting surface into a wavefront-shaped reference luminous flux and outputs this reference luminous flux; this light beam measurement apparatus can carry out both wavefront measurement and light beam spot characteristic measurement on a light beam simultaneously.

First, a first exposure process is performed using dipole illumination with only a grating-pattern forming region as a substantial object to be exposed. Next, a second exposure process is performed with only a standard-pattern forming region as a substantial object to be exposed. A development process is then performed to obtain a resist pattern. A mask for the first exposure process is such that a light blocking pattern is formed on the whole surface of a standard-pattern mask part corresponding to the standard-pattern forming region. A mask for the second exposure is such that a light blocking pattern is formed on the whole surface of a grating-pattern mask part corresponding to the grating-pattern forming region.

The apparatus of the present invention includes an inverted J-shaped pipe disposed under the sea and including shorter and longer open end portions, and a connecting portion joining them such that the shorter and longer portions extend downward from connecting portion to their respective open ends. An injector nut injecting the carbon dioxide-containing gas into a portion of said short pipe adjacent to said first open end into said shorter pipe. An accumulator is in fluid communication with the connecting portion for collecting gas, which remains undissolved in the seawater during the passage of the carbon dioxide-containing gas through said shorter pipe. According to the method of the invention, the injection of the carbon dioxide-containing gas forces the seawater to enter into first open end, to flow upward together with the carbon dioxide-containing gas through the shorter pipe portion, to flow downward through the longer pipe portion and to be discharged from the second open end, with the carbon dioxide being dissolved in the seawater during the passage of the carbon dioxide-containing gas through the shorter pipe portion, so that the seawater discharged from the second open end contains carbon dioxide dissolved therein.
