Title: Method and device for flat surface of thin plate-like work
Inventor: KATO TADAHIRO
IPC: B24B37/30
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To enable flat surface grinding to be carried out without transferring almost no waving on the surface of work by performing polishing work through reduction of negative pressure to suctionwise fix the thin plate-like work at the terminal time of grinding. SOLUTION: A wafer 1 is suctionwise retained by a high vacuum pressure type negative pressure source 23 until fine grinding operation is performed, and at the transfer time to the spark-out changeover is made to a low vacuum negative pressure source 24 to perform low negative pressure suction is carried out. As a result, until the fine grinding work for performing grinding wheel cutting in is made, a work is retained with the firm suction force close to the vacuum contition, but after the transferred time of spark out at which the feeding pressure of grinding wheel is reduced or close to almost the nothing level, the suction force is reduced so that the retaining force is maintainable.  Flat surface grinding can be made under the condition where the elastic deformation force of wafer 1 is released substantially until the fine grinding work and waving which can not remove due to the elastic deformation is removed, thereby maintaining the wafer shape without waving or with a less waving after being subjected to surface grinding even if the suction is released.

Title: Surface hardening method
Inventor: OHATA KOKICHI
IPC: C23C14/32
Filed: 1990-03-30
Abstract: PURPOSE:To obtain a hardened surface layer without any clear boundary with a substrate and excellent in adhesion and wear resistance by irradiating the substrate surface with N ion while vapor-depositing a metal on the surface and reducing the concn. of the nitride formed from the surface toward the inside. CONSTITUTION:An ion source 5 for irradiating a water-cooled rotary substrate holder 3 with N ion 4 from an angle of 45 deg. and a source 7 for Ti vapor 6 are provided in a chamber 2 evacuated by a vacuum pump 1. The surface of a substrate 8 is irradiated with an N ion beam 4 while vapor-depositing Ti on the surface to form a Ti film on the substrate 8 surface. In this case, the TiN concn. is reduced from the substrate 8 surface toward the inside, and the ratio of the characteristic values by X-ray diffraction from the (200) and (111) faces of the TiN (I200/I111) is set to <=1.0. Consequently, the obtained surface layer has the above-mentioned characteristics, the hardness is drastically improved, and the method is more effectively applied to an Al alloy, etc., since the alloy is treated especially at low temp.

Title: Detection of blowing rate of boron compound in to melt reduction furnace for production of metal containing boron
Inventor: KATAYAMA EIJI
IPC: C22C33/04
Filed: 1982-05-15
Abstract: PURPOSE:To control the blowing rate of a B compd. exactly and to improve the yield of B-contg. metal by detecting the blowing rate of the B compd. into a melt reduction furnace from the quantity of light of the specific wavelength by the flame reaction that takes place in a high temp. atmosphere in the furnace at the tuyere end of the furnace. CONSTITUTION:A B compd. is blown together with high temp. air 5 through the tuyere 3 and/or 4 of a melt reduction furnace 6 in production of ferroboron. Iron ore and limestone are also blown through the tuyere 4. A raceway 8 is formed at each tuyere end by a carbonaceous solid reducig agent layer 7, and a formed gas 9 flows upward and is discharged. The blown B compd. is melt reduced and the B-contg. metal 10 absorbed in the descending Fe-C-Si metal and slag 11 accumulate. The B compd. blown here causes flame reaction by contact with the temp. atmosphere and generates the luminous flux having essentially 0.59-0.53mu wavelength. The quantity of said light is proportional to the amt. of B. Therefore, said quantity of the light is taken out as electric current with a photoelectric element 16, and is detected as the blowing rate of B in accordance with the predetermined correlation between the quantity of light and electric current.

Abstract: PURPOSE: To facilitate the adjustment of the tensile force of a track by enabling the forward and backward motion of a support shaft under the condition that it is fixed to each slide rail in the lateral direction thereof.  
     CONSTITUTION: When the nut 33 of a tensile force adjusting device 30 is rotated normally or reversely by a socket wrench L inserted through the opening 16a of a track 16, a bolt 32 makes forward and backward movement against a bracket 20 and a sliding member 31 also moves forwards and backwards within a guide space 20A of the bracket 20. By this, a support shaft 14, not being released from its fixation in the lateral direction, makes forward and backward motion along and inside a long slot 24, thereby the position of a guide wheel 15 supported axially by the support shaft 14 being adjusted and thus the tensile force of the track 16 touching the wheel being also adjusted. Moreover, since the bolt 32 is given the tensile force of the track 16 at the forward force through the intermediary of the wheel 15, the support shaft 14 and the sliding member 31, there is no need to apply fastening thereto.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an ATM(asynchronous transfer mode) communication system which minimally suppresses bad effects that are given to the path of a main signal when a shaping operation continues on the occurrence of burst traffic. SOLUTION: A shaping functioning part of this ATM communication system performs the state supervision and setting of a main signal path about main signal memory 3 and 4 and other signal paths, and is also provided with an F/W-INF 12 that serves as an interfacing part with an external host CPU which writes a minimum cell interval value in parameter memory 9. Because a main signal memory controlling part 2, an operation memory controlling part 8 and a parameter memory controlling part 7 change memory control and stop a shaping operation that is performed by a shaping processing part 6 when a failure occurs on hardwares except the main signal path about the memory 3 and 4, bit errors in a cell, cell losses and occurrences of wrong distribution are minimally suppressed except when the entire memory 3 and 4 fails and a shaping operation can be continued.

Filed: 1992-03-03
Abstract: PURPOSE:To enhance the safeness of operations by a method in which the releasing of steering brake is made preferentially to that of a brake for running and the steering action of the body is started smoothly. CONSTITUTION:A preferential switch valve 41 is provided on the way of a branched pipe 28 connecting a shuttle pipe 33 provided on the way of a brake pipe 25 for running with a steering brake pipe 27. The valve 41 is positioned usually on a closing position (a) by a spring 41B, and after a switch valve 34 is switched from a discharge position (a) to a supply position (b) by pressurized oil for releasing brake, the hydraulic oil is supplied to a hydraulic pilot part 41A to switch the valve 41 to the supply position (b). For this reason, when the control valve 20 for steering is switched from the neutral position (a) to switch positions (b) and (c), the pressurized oil for releasing brake can be preferentially supplied to the steering brake 10 rather to the brake 8 for running. The brake releasing of the steering brake 10 can thus be quickly made.

Title: Tunnel junction type solid-state electronic device
Inventor: SAI CHIYOUSHIN
IPC: H01L39/22
Filed: 1987-04-01
Abstract: PURPOSE:To improve frequency characteristics or integration density, by including a tunnel junction, which is formed by two planes of two metal films, so that said two planes are intersected at a specified angle, with a perpendicular to the plane of a tunnel barrier as an axis. CONSTITUTION:A first metal film 1 and a second metal film 2, each having a specified shape, are coupled at the side parts through a tunnel barrier. The films are electrically insulated at a part other than the tunnel barrier. Both metal films 1 and 2 include a tunnel junction 3. The junction 3 is formed by two planes, which are intersected at a specified angle, with a perpendicular to the plane of the tunnel barrier as an axis. Namely, the area of the tunnel junction is determined by t1t2/sin theta, where t1 is the thickness of the first metal film 1, t2 is the thickness of the second metal film 2 and theta is the crossing angle of the two planes. When theta=pi/2 for simplicity, the area is determined only by the thicknesses of the metal films. Therefore, very minute tunnel junction can be implemented with good reproducibility. Thus the frequency characteristics or the integration density of the tunnel junction type solid-state electronic device can be improved.
