摘要： PURPOSE:To improve the surface roughness with maintaining the characteristic of the fluid permeability by a void by forming a porous thermal spraying layer in the specified thickness on the surface including the void opening part so as to include at least the part where the void part of the skelton of a ceramics porous body is opened. CONSTITUTION:The ceramic porous body 22 arranged and fixed inside a cast cavity 20 is made hollow at its skelton itself forming the porous structure and formed with a continuous void inside the skelton. Under the state of arranging the ceramic porous body 22 of such a structure inside the cast cavity 20, a molten metal 26 having the chemical component controlled according to the physical property requested for the casting is poured. This pouring molten metal 26 is guided into the cast cavity 20 through a pouring sprue 30 and runner 16, fed to a riser 18 with filling up the gap between the skeltons 34 of the three-dimensional network structure of the ceramic porous body 22 and the pouring work is completed.

摘要： PURPOSE:To improve the fatigue strength of a soft-nitrided product, by subjecting an iron-base metal to shot peening after soft-nitriding so as to produce residual stress in a diffusion layer without embrittling a top compd. layer. CONSTITUTION:An iron-base metal is soft-nitrided to form a compd. layer on the top and a diffusion layer contg. nitrogen just under the compd. layer. The soft-nitrided metal is subjected to shot peening with glass beads of about 0.1-0.6phim/m particle size at 0.$-0.3m/m arc height to produce residual compressive stress in the nitrogen-affected layer including the diffusion layer without embrittling the top compd. layer. Thus, the fatigue strength of a soft-nitrided product is made higher than that of a conventional product by about 20%.

摘要： PURPOSE: To improve the recovery rate of halogenated hydrocarbon solvents from waste liquid by performing vacuum distillation with an ejector with said solvents as working fluid then switching this to vacuum distillation with an ejector using water as working fluid.
CONSTITUTION: Waste liquid of halogenated hydrocarbon solvents contg. fats or oils is put through a lead-in port 2 into an oven 1, where it is heated with a heater 5; at the same time, with the same solvents in a receiving tank 3 as working fluid, a pump 4 is operated to feed the solvents forcibly in an arrow 6 direction and to pass the same through an ejector 7, thereby evacuating the inside of the ejector and sucking the solvents evaporated in the oven 1. The solvents are fed into the tank 3, where they are cooled with a cooler 17a. Upon completion of this recovery operation, a pump 11 is operated to suck the solvents remaining in the vessel 1 with a water ejector 12, so that they are dropped together with water into a water tank 10. Since the inside of the tank 10 is partitioned with a metallic screen 9 and the moving speed of the water is made low, the water and the solvents separate and the solvents are removed through a take-out port 16.

摘要： PURPOSE: To prevent the enviromental pollution around a washing apparatus by diagnosing the airtightness in the space between double seal rings and issuing a command not executing washing work or passing a part of a washing process to complete washing when there is a problem in airtightness. CONSTITUTION: After a washing part 3 is housed in a washing chamber 1 so as to be placed on a stand 6, an airtight door 2 is hermetically closed by a clamp 9. By this constitution, an annular space 5 is demarcated by the opening flange part, airtight door 2 and two seal rings 10, 11 of the washing chamber 1. A three-way valve and a compressed air supply valve are opened to supply compressed air into the space 5 from a piping line 20 so that the pressure in the space 5 becomes a definite value. Thereafter, a supply main valve is closed and the lowering of the pressure in the space 5 is measured by a compressed air pressure detector PS. If there is no leak, a washing process is started and, when a leak amt. is a set value or more, a warning is issued to stop the transfer to a next process.

摘要： PURPOSE:To attain efficient partial nitriding of machine parts, etc., by coating parts to be nitrided with a nitriding agent and carrying out heating in a nonoxidizing atmosphere. CONSTITUTION:When machine parts, etc., made of iron-based stock are partially nitrided, parts to be nitrided are coated with a cyanic acid-based nitriding agent and heating is carried out in a nonoxidizing atmosphere or an atmosphere regulated to a prescribed nitrogen potential. When machine parts, etc., made of steel stock contg. >=5% Cr are partially nitrided, parts to be nitrided are coated with chemicals for destroying oxidized films on the surfaces of the parts and heating is carried out in an atmosphere regulated to a prescribed nitrogen potential. Nitriding is applied to an extended range and the performance of the machine parts, etc., can be enhanced.

摘要： PURPOSE:To efficiently remove a salt mist from mist-contg. steam and to recover the salt in a molten salt bath by heating the cleaning water, supplying the heated water to the bath, bringing the heated water into contact with the free surface of the bath and passing the generated mist-contg. steam through a curtain of molten salt. CONSTITUTION:Salts are recovered from the salt-contg. cleaning water which has been used to clean a solid brought into contact with the molten salt in the molten salt bath. In this case, a box 3 having the open bottom dipping under the free surface of the molten salt bath 2 and a steam discharge pipe 4 at the top is provided, and the mist blocking device 1, on which molten salt curtains 12 and 13 are formed, is prepared in the box 3. The salt-contg. cleaning water as or the heated water is supplied to the bath 2 from a pipe 10 and brought into contact with the free surface of the bath 2, the generated mist- contg. steam is passed through the curtains 12 and 13, hence the salt mist is removed from the steam, and the salt is recovered in the bath 2. As a result, the salt mist is efficiently collected, and the contamination of the peripheral devices is prevented.

摘要： PURPOSE:To improve durability, to reduce the generation of distorsion and to improve the reliability of quality by forming a cam portion and a journal portion by solid casting using soft nitriding steel material having a specified composition, machining same and applying soft nitriding treatment to same. CONSTITUTION:A cam shaft 8 has a cam portion 9 and a journal portion 10 which are formed by solid casting. In this case, the cam portion 9 and the journal portion 10 are formed by solid casting using soft nitriding steel material set in such a manner that C: 0.1-0.6%, Cr: 0.05-2. 5%, Al : 0.2%max, V: 0.03-0.25%, Mo: 0.25% or less). Thus both a cam surface and a rotary shaft are excellent in wear-resistance, seizure-resistance and pitching resistance, and the generation of distorsion after soft nitriding treatment can be reduced so as to obtain stable quality.

摘要： PURPOSE: To enhance the recovery efficiency of a solvent for washing parts, by a method wherein the solvent adsorbing amount of activated carbon is restricted in a difinite range of a saturation amount or less while excessive air is mixed in desorbed gas.
CONSTITUTION: When adsorption and desorption is repeated while adjusting the solvent max. content of activated carbon to 20W30%, the solvent content of desorbed air comes to max. 2W4mg/l. This test is performed by a method wherein exhuast gas sent into an activated carbon adsorbing tank 4 from a washing tank 2 by a vacuum pump 3 is adsorbed and, thereafter, air is mixed into an exhaust gas pipe D from a blower 6 to be discharged while diluting the solvent content to a restricted value or less. In this method, the solvent slightly remaining in the washing tank 2 is exhausted at every washing. Because the washing tank 2 is a hermetically closed system, the loss of the solvent is not almost generated if washing is stopped. The activated carbon adsorbing tank of this mthod intermittently repeats adsorption and desorption by using one tank with a volume of about 100l relative to the washing tank (about 1m
3 ) of 500W 600kg/one time and, therefore, equipment cost is low and maintenance is easy.

摘要翻译：目的：为了提高洗涤部件的溶剂的回收效率，通过在脱附气体中混合过量空气的同时将活性炭的溶剂吸附量限制在饱和量以下的二极性范围内的方法。构成：当调整溶剂时重复吸附和解吸最大值。活性炭含量为20-30％，解吸空气的溶剂含量达到最大。 2-4mg / L。该试验是通过吸附由洗涤槽2输送到活性炭吸附槽4中的废气被吸附的方法进行的，其后，从鼓风机6将空气混入排气管D中以排出同时将溶剂含量稀释到限制值以下。在该方法中，在洗涤槽2中稍微残留的溶剂在每次洗涤时都被排出。由于洗涤槽2是气密封闭的系统，所以如果洗涤停止，则几乎不产生溶剂的损失。使用这种马氏体的活性炭吸附槽通过使用相对于洗涤槽（约1m 3）的一个容积为约100l的一个罐为500-600kg /一次，间歇地重复吸附和解吸，因此设备成本低维护方便。
