摘要： A spacer arranged inside a water jacket which is formed to surround peripheries of cylinder bores in a cylinder block of an internal combustion engine includes support legs extending in an up-and-down direction from a spacer main body part which partitions the water jacket into an upper and lower cooling water passages. The support legs are disposed in opposite end portions in a cylinder row line direction, where the temperatures of the cylinder bores tend to be lower. Accordingly, even if the flow of cooling water is more or less inhibited by the support legs and the cooling effect deteriorates, it is possible to prevent the temperatures of the respective cylinder bores from becoming different by suppressing the influence to a minimum.

摘要： A spacer fitted inside a water jacket of a cylinder block in an internal combustion engine is set so that a space formed between an inner peripheral surface of the spacer and an inner wall surface of the water jacket is smaller than a space formed between an outer peripheral surface of the spacer and an outer wall surface of the water jacket. Accordingly, even if a position of the spacer is shifted in a radial direction, the inner peripheral surface of the spacer comes into abutment on the inner wall surface of the water jacket at first. Thereby, the abutment of the outer peripheral surface of the spacer on the outer wall surface of the water jacket is prevented completely. Therefore, hitting sounds of pistons can be blocked by the space between the outer peripheral surface of the spacer and the outer wall surface of the water jacket.

摘要： An intake manifold made of a synthetic resin includes a surge tank, and a plurality of intake pipes disposed in parallel to one another and each having a rising pipe portion which is connected to a lower portion of the surge tank and extends upwards. A space is defined between the surge tank and each of the rising pipe portions, as viewed sideways. In order to enable an increase in volume of the surge tank, while avoiding an increase in size of the intake manifold, the surge tank (20) includes a main tank portion (20a) extending in a direction (28) of arrangement of the intake pipes (21A to 21D) and opposed to the rising pipe portions (29A to 29D) of the intake pipes (21A to 21D), and a sideways-bulged portion (20b) which is bulged from an intermediate portion of the main tank portion (20a) as viewed in the arrangement direction (28) and is interposed between a pair of rising pipe portions (29B, 29C) disposed at the intermediate portion as viewed in the arrangement direction 28. Inner ends of a pair of the spaces (38) defined respectively between the rising pipe portions (29A to 29D) and the main tank portion (20a) on opposite sides of the sideways-bulged portion (20b) are closed by opposite sidewalls of the sideways-bulged portion (20b).

摘要： An appearance inspection apparatus for inspecting a surface of a printed circuit board requires high inspection accuracy and inspection time reduction. To this end, the apparatus has a scan head that scans an object under inspection and generates image data of the surface of the object. The scan head includes a vertical light source which projects light on the surface from right above the object and a side light source which projects light sidelong on the surface. A lenticular sheet is provided between the vertical light source and the object in order to adjust the vertical light and improve the inspection accuracy in a vertical light test. In a side light test, light sources other than the central part in the vertical light source is turned on and an auxiliary light is projected along with the side light, so that the dynamic range for the inspection can increase.

摘要： A first pipe is press-fitted into a second pipe having an inner peripheral surface, circular in section, about an axis of the second pipe. The first pipe, having an outer peripheral surface provided with recesses each located between arcuate portions, and which recesses have the same radius about an axis of the first pipe and are located at a plurality of circumferentially spaced-apart points, The recesses are each located radially inwardly of a phantom circumferential extension of the arcuate portions to extend axially over a predetermined length of the first pipe. Thus, it is possible to relatively enlarge the press-fit margin leading to an elongation limit and to set the dimensional accuracy of the pipe product at a relatively low value by the fact that when the first pipe is press-fitted into the second pipe, the second pipe flows so as to fill a gap produced between the first and second pipes due to the plurality of recesses provided on the outer peripheral surface of the first pipe, as well as by the fact that the first pipe is easy to deform under compression at the recesses.

The first structural member P1 is provided integrally with an inlet part 21 forming at least part of an inlet passage 11 and including the inlet flange 22. The outlet flange 40 is formed integrally with the inlet part 21 so as to extend across a direction in which the inlet passage 11 extends, two bolts 451 and 452 for fastening the outlet flange 40 to the cylinder head are disposed respectively on the opposite sides of the inlet passage 11. The rigidity of the inlet flange and fastening of the outlet flange to the cylinder head by fastening means improves a vibration reducing effect on a throttle device joined to the inlet flange.

摘要： The present invention is an appearance inspection apparatus and method utilizing multiple light sources in a lighting unit 30 to alternately irradiate, line by line, side light from a side light source and slit light from a slit light source onto board 1 to be inspected. A correction value memory unit stores digital correction values required for correcting shadings for the side light source and the slit light source and an analysis unit utilizes these digital correction values to correct shadings on the image data. A highly accurate image is thus obtained.

摘要： An appearance inspection apparatus and method using at least one telecentric lens, although at least two is preferred and at least a corresponding number of line sensors arranged in parallel with the image capture direction for inspecting a large circuit board. When two lenses are used two images are formed, which partially overlap each other. If image data for one line is captured in this state, a scanning head having two sets of telecentric optical systems move one line at a time in the driving direction. By repeating the same steps, data for two image segments which partially overlap throughout the entire line of board are obtained. The two image segments are synthesized after displacement of positions when colors in the overlapping portion of the two pieces of images are corrected. Inspection of board is then performed based on the combined image.
