Abstract: PURPOSE:To maintain the green density of a porous body as prescribed and to obtain a bearing of good performance free from clogging in gas supply face by forming a relief part to the porous body prior to sintering of a green compact molding consisting of an insert member and powder for sintering. CONSTITUTION:Copper atomized powder is compaction-molded together with an insert member 2 consisting of mild copper or the like with a compaction molding machine (not shown), whereby a green compact molding 11 of desired density is obtained. The outside circumferential surface of the molding 11 molded in ont body with the member 2 is machined down to depth (d) by means of a tool 13, whereby a relief part 11a is formed during machining of the fitting surface 10 of the member 2 to a fixing member 3. Thence, the molding 11 is sintered at prescribed temp. to diffuse and join the member 2 to the molding 11, whereby a desired porous body is obtained. This is incorporated as a gaseous bearing for a revolving shaft 4 by a fixing member 3. Gas is supplied through a gas passage 5, a gas chamber 6 and a gas supply face 7 then through the molding 11 which is a porous body, to the bearing surface.

IPC: F27D17/00
Filed: 1981-01-14
Abstract: PURPOSE: To recover metals, chiefly Zn and Pb and to make massively solidified slag unslakable by adding electric furnace dust and a reducing agent to molten slag in an electric furnace.  
     CONSTITUTION: Electric furnace dust and a reducing agent are added to molten slag in an electric furnace while blowing a bubbling gas into the slag. During  this time, volatilized metallic oxides, chiefly Zn and Pb oxides are recovered  with a bag filter for direct suction from the furnace, and harmful matter in the  dust is made harmless. Thus, by adding the reducing agent, the volatilization  rates of Zn and Pb are enhanced.

Title: Cutting device of block
Inventor: SHIMIZU KAORU
IPC: B24B27/06
Filed: 1980-01-19
Abstract: PURPOSE:To reduce the deterioration of wire guide rollers in a cutting device of blocks which uses a wire lapping cut-off mechanism by blowing off lapping compounds and cutting chips sticking to the wire by air. CONSTITUTION:Air 10 is blown continuously against a wire 4 reciprocating in the directions of arrow marks from the holes 9 of pipes 8. In this state, blocks 1 are contacted to the wire 4, and then by supplying lapping compounds to the contacting part of the blocks 1 and the wire 4, blocks 1 are lap-cut. During this operation, lapping compounds or cutting chips sticking to the wire 4 are blown off by air 10 and the sticking of lapping compounds to wire guide rollers 5a, 5b and 5c decreases, and as a result, the deterioration of the wire guide rollers is reduced and the life of the rollers is lengthened. Further, the amount of cutting chips sticking into the rollers decreases and tension pitch shift of the wire is eliminated.

Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of calculating times of mutual transmission coefficients and the number of calculating times of the Fourier transformation of a mask by systematically changing each condition, such as the coherence factor, a mask condition, and an optical condition by deciding the changing order of each condition. SOLUTION: After an optical condition is set, the mutual transmission coefficients to the maximum degrees Lmax and Mmax which vary depending upon the maximum value of a coherence factor δ and the minimum value of the cycle frequency (f) of a mask pattern are calculated and tabulated. After a mask condition is set, the Fourier transformation of a mask to the maximum degrees Lmax and Mmax which vary depending upon the maximum value of the coherence factor δand the cycle frequency (f) of the mask pattern decided by the mask condition are calculated and tabulated.  Then the intensity distribution of light is repetitively calculated by changing the coherence factor δ by using the tables and the formula (where, t, t, t, and T respectively represent the complex amplitude transmission coefficient of the mask, the complex conjugate of t*, the Fourier transformation of t, and mutual transmission coefficient). In addition, the abovementioned calculation is repeated by changing the mask condition and optical condition.

Filed: 1982-01-18
Abstract: PURPOSE:To manufacture compound semiconductor crystal having controlled stoichiometric composition using LEC process, by supplying the molten liquid with volatile  elements from the outer wall of the crucible, thereby maintaining the concentration of  the volatile element in the molten liquid at a constant level. CONSTITUTION:A volatile element As 6' for compensation is put into the outer crucible,  and a porous crucible is inserted into the outer crucible. The raw materials composed  of Ga 18 and As 19 are charged into the porous crucible at a specific ratio, covered  with a B2O3 disc 7', and heated with the upper heater 10 to melt the B2O3 disc 7'. The  outer crucible is lifted with the susceptor under rotation, and Ga 18 is molten to synthesize molten GaAs 5. In the above process, the As for compensation is heated with  the lower heater 11 to a definite temperature. Although the raw material As 19 is dissipated through the molten B2O3 during the pulling growth of single crystal Cr through  the molten B2O3 using a seed crystal, the mixture in the porous crucible is maintained  to the stoichiometric composition by the diffusion of the compensation As 6' through the wall of the porous crucible into the molten GaAs 5.

Title: Electrophotographic copying device
Inventor: WATANABE TAKESHI
IPC: G03G15/20
Filed: 1990-01-17
Abstract: PURPOSE:To make it possible to use a device fro a long time and to perform excellent fixing without offset by setting a releasing agent applying member so that it may be allowed to abut on a roller with a specified press-contact force and may separate from the roller after a specified time and setting the specified press-contact force or the specified time at higher values as image ratio becomes higher. CONSTITUTION:In the case of performing a copying action, a solenoid 17 is driven so that the releasing agent applying member 7 may be allowed to abut on the fixing roller 1 with the specified press-contact force when a transfer material reaches the fixing roller and a pressure roller at latest and the member 7 may not abut on the roller 1 again after the specified time. Since the press- contact force is made strong or the contact time is set long when the image ratio is high, the offset is surely prevented even when the image ratio is high, and a releasing agent is prevented from being consumed wastefully because the press-contact force is made weak or the contact time is set short when the image ratio is low. Thus, the device can be used for a long time and the excellent fixing without offset is performed.
