摘要： PURPOSE:To make it possible to make a super clean space where the diffusion of dusts and dirts is small by setting a small opening degree of floor plates close to an under-floor return port, and setting a large opening degree of floor plates farther from the return port. CONSTITUTION:The opening degree of floor plates 6 are made larger from the position of an air return port 8 successively in the order of a region (a), a region (b) and a region (c). As a result, in the air flow the concentration of an air current to parts close to the air return port 8 is reduced as shown by arrow 11, and the horizontal air flow is substantially eliminated. Thus, the air flow becomes substantially a vertical air flow, and a down flow is realized. As a result, diffusion of dusts and dirts can be prevented, and improvements in the yield of the product and reliability therefor are realized.
摘要翻译：目的：通过将地板板的小开度设置在靠近底板返回口的地方，可以使粉尘和污垢扩散的超洁净空间变小，并将较大的开口度设置在更低的地板上返回端口。构成：按照区域（a），区域（b）和区域（c）的顺序，从空气返回口8的位置开始使地板6的开度更大。结果，在空气流动中，如箭头11所示，气流对接近空气返回口8的部分的浓度降低，并且基本上消除了水平空气流。因此，空气流变成基本上垂直的空气流，实现向下流动。结果，可以防止粉尘和污垢的扩散，从而实现产品的产量提高和可靠性的提高。

摘要： PURPOSE:To prevent dust from diffusing from a region where dust is liable to be generated to a region where cleanness should be maintained by providing a difference in the air flow speeds depending on the character of the region so that the blow-off speed of the air flow in a passing region becomes greater than that in a working region. CONSTITUTION:When as a blow-off air flow from a filter 4, the blow-off speed in a working region 6a is made larger than a blow-off air flow speed in a passing region 6b, air on the low air flow side is induced to the high air flow side. Thus, dust is diffused by offsetting to the high air flow speed side, and air on the low speed side has a low dust concentration. Hence, diffusion of dust to the low air flow side cannot almost be observed. As a result, the yield of the product and reliability therefor can be improved.
摘要翻译：目的：为了防止灰尘从易于产生灰尘的区域扩散到通过根据该区域的特性提供空气流速的差异来保持清洁度的区域，使得吹扫速度通过区域中的空气流量变得大于工作区域中的空气流量。构成：作为来自过滤器4的吹出空气流，工作区域6a中的吹出速度大于通过区域6b中的吹出空气流速，低气流侧的空气为诱导到高气流侧。因此，灰尘通过偏移到高空气流速侧而扩散，低速侧的空气的灰尘浓度低。因此，几乎不能观察到灰尘向低空气流侧的扩散。结果，可以提高产品的产量和可靠性。

摘要： PURPOSE: To increase the sound consuming effect in a filter unit by inter posing the air path holding materials between the gaps of filter medium, holding these with a rectangular frame and providing the gaps of the filter medium slantingly for the air current direction.
CONSTITUTION: A filter unit 46 is constituted of a rectangular frame 48 and filter mediums 50,52 folded in 99 times are set together with the zigzag space holding materials 53 which are interposed between the gaps thereof in the inside of the fame and the gaps are slanted in 30 for the air current direction shown by an arrow A. The air current is flowed along the flow path in chevron between the filter mediums 50, 52 and the essential component of sound wave is passed through the same passage as air current and therefore the noise is consumed by the flex of the filter mediums.

摘要： PURPOSE:To make a three-dimensional quake-free and vibro-isolating effect securable, by disposing laminated rubber in space between the side of a frame and a longitudinal wall of a framework supporting this frame, thereby letting it support load in a horizontal direction. CONSTITUTION:A framework 32 is supported on a base plate 10 via laminated rubber devices 26 and 26. In addition, this laminated rubber 26 is disposed in space between the side of a frame 24 and a longitudinal wall 34 of the framework 32 in a state of being compressed with preload imposed in advance. Therefore, the load in a vertical direction is supported by the laminated rubber 26 to be disposed between the base plate 10 and the framework 32, while the load in a horizontal direction is supported by another laminated rubber 26 to be disposed between the frame 24 and the longitudinal wall 34, so that these rubber devices come to have a quake-free/vibro-isolating effect against vibrations in three-dimensional directions in consequence.

摘要： PURPOSE:To provide the air purifying agent which has the excellent performance to remove harmful gases, such as HF, HCL, SO2, NH3, and H2O2, and does not degrade the strength of active carbon at the time of depositing an alkali to the active carbon and the process for producing this agent. CONSTITUTION:The air purifying agent consists of a grid-shaped active carbon molding deposited with the carbonate of group 1 of element periodic table; for example, potassium carbonate, potassium hydrogencarbonate, etc. Such air purifying agent is produced by immersing the active carbon in a potassium carbonate soln., then drying the active carbon by heating to >=70 deg.C. The air purifying agent obviates the heat generation of the active carbon, decreases the generation frequencies of cracks at the time of drying and less degrades the strength of the active carbon as compared with the air purifying agent obtd. by impregnating the hydroxide of alkaline metals, such as NaOH and KOH, into the active carbon and drying the active carbon by heating.

摘要： PURPOSE:To facilitate a replacement of a gas adsorption filter for use in removing toxic gas generated within a clean room. CONSTITUTION:Since a gas adsorption filter is fixed to a grating 16, toxic gas can be effectively removed and a replacement of the gas adsorption filter can be easily carried out. This gas adsorption filter is comprised of grid-like structure active carbons 40 arranged and disposed within a frame 52. The active carbons 40 are formed with grid-like through-pass holes 42, so that a pressure loss of an air flow passing therethrough is low. In addition, shock absorbing materials 46 are disposed among the active carbons 40 and a dust removing filter 56 is disposed at a downstream side of it, so that the number of generated fine particles from the active carbons 40 is low.

摘要： PURPOSE:To facilitate a replacement of a gas adsorption filter for use in removing toxic gas generated within a clean room. CONSTITUTION:Since a gas adsorption filter is fixed on a filter device 14 of a ceiling room 15, an air supplying power is reduced and a fixing of the gas adsorption filter may easily be carried out. This gas adsorption filter is comprised of grid structure active carbons 40 arranged and disposed within a frame 52. The active carbons 40 are formed with grid-like through-pass holes 42, so that a pressure loss of air flow passing therethrough is low. In addition, some shock absorbing materials 46 are disposed among the active carbons 40 and a dust removing filter 56 is disposed at a downstream side of the active carbons 40, so that the number of generated fine particles from the active carbons 40 is low.

摘要： PURPOSE:To remove hazardous gas generated in a clean room. CONSTITUTION:The gas removing device 50b is composed of grid-like activated carbon 40 arranged in plural alignments inside a framed body 52. Since the activated carbon 40 is formed with grid-like through-holes 42, the pressure loss of a through air flow is small. Also, since a buffer material 46 is provided in the activated carbon 40 and a dust removing filter 56 is provided in a downstream, the number of particulates generated from the activated carbon 40 is small. Such a gas removing device 50b, whose air draft resistance is 3mm water column or less and preferably 1mm or less, is provided on a part of an air circulating passage 17b.
