Title: Method for finishing tooth surface of gear
Inventor: HOSOYA NORIO
IPC: B23F19/05
Filed: 1986-06-04
Abstract: PURPOSE:To lap tooth surface uniformly smoothly and diminish projecting portions along tooth trace for reducing substantially noises in gearing by using for a tool a reference gear meshing a gear to be worked to swing them radially along the tooth form. CONSTITUTION:When working liquid is supplied between a gear W to be worked and a reference gear S meshing with each other while a drive shaft d is rotated forward, the gear S is pivoted in the direction Z1 while swing levers 9, 9 are swung about a pivot 8 in the directions r1, r2 by a rotatable lever 12 pivoted drivably in a through hole i by a prime mover N. Thus, since the gears 5, 6 always slidably contact each other along the directions r1, r2 from the beginning to end of the engagemenmt with each other, the tooth surfaces f1.f2 of gear W and simultaneously finished are lapped by the tooth surfaces of gear S having the hardness and accuracy as a tool while being prevented from unexpected wear, cracks, etc. of the tooth surfaces f1, f2 of gear W by the swing of gear S in the directions r1, f2. And after the drive shaft d is rotated forward by the proper number of times, when the drive shaft d is reversed by the same under of times, the tooth surfaces f1, f2 of gear W can be finished uniformly.

Title: Traveling speed control unit to farm tractor
Inventor: AZUMA TOMOAKI
IPC: F16H63/12
Filed: 1981-08-14
Abstract: PURPOSE: To positively insure the cultivation, insemination and fertilization works of a farm tractor by optionally selecting an automatic control valve of a speed control unit to either an off-functional or an auto-functional position.  
     CONSTITUTION: While an automatic control valve 43 is functioning, a workload increase is detected by a pressure regulator valve 49, that is a load detector, and the valve 43 is shifted toward a low speed position, so that it may control feed/discharge switching of hydraulic oil to plural hydraulic pressure clutches 32, 33 and 34 for  forward speed shifting, and the traveling speed is placed under control. Thus various farm works are insured under the constant condition. While the feed/discharge  of the hydraulic oil to the hydraulic pressure clutches 32W35 is switched manually,  the valve 43 is set to an off-functioning position and on/off switching of the  hydraulic pressure clutches 32W35 is controlled by a manually operated switching  valve 41. Therefore the traveling speed control of a tractor is manually practicable  and an operator can appropriately carry out various farm works such as insemination, fertilization, etc.

Title: Manufacture of semiconductor wafer
Inventor: IEIRI KENJI
IPC: C30B31/06
Filed: 1989-05-22
Abstract: PURPOSE:To improve the yield of wafers and reduce the manufacturing cost by grinding and eliminating a high concentration surface layer on the single side of a wafer before impurity diffusion. CONSTITUTION:A high concentration surface layer containing impurity element is thinly formed on both surfaces of a silicon wafer; the wafer is taken out from a diffusion furnace; its single surface of thickness a little thicker than the high concentration surface layer is ground by a diamond grinding machine or the like; thus the high concentration surface layer on one side is completely eliminated. The wafer after grinding is again heat-treated in the diffusion furnace, and a thin oxide film is formed on the whole surface. Further the wafer on which the oxide film is formed is heat-treated, and impurity atoms are diffused in the inside of the wafer as far as the desired depth from the left high concentration surface layer. Then a ground surface is polished, and a mirror surface is formed, thereby obtaining a product wafer. Thereby the elimination amount of silicon can be reduced, and the yield of material wafers can be improved.

IPC: F23N3/08
Filed: 1994-05-17
Abstract: PURPOSE:To keep a blast amount at a proper value even when exhaust gas resistance is increased and resistance of a drive mechanism is increased and to detect rotation abnormality of a blower by a method wherein when the number of revolutions of the blower under combustion is below the reference number of revolutions, a drive voltage is increased and when it exceeds the reference number of revolutions, drive is performed at a reference drive voltage. CONSTITUTION:When control of an air-fuel ratio is started, a demand fuel gas amount is decided and a fan motor 26 is driven and the current actual number (n) of revolutions is detected by a number of revolutions detecting part (29). A detecting actual number (n) of revolutions is compared with the reference number (N) of revolutions prestored at a memory part 27 by a comparing part 28. When the actual number (n) of revolutions is below the reference number (N) of revolutions, a drive voltage is increased so that the actual number (n) of revolutions is increased to a value equal to the reference number (N) of revolutions. When, even if a drive voltage is increased, it is below the allowable number of revolutions on the minimum side and a limit time elapses, a main salenoid valve is closed to stop combustion. Further, when the actual number (n) of revolutions exceeds the reference number (N) of revolutions, a reference drive voltage is kept and combustion is continued.

Title: Method for controlling plate crown and shape in continuous rolling mill
Inventor: ITO NOBUAKI
IPC: B21B37/38
Filed: 1994-06-10
Abstract: PURPOSE:To secure a shape between stands by optimizing the setting of a specific curve, and reducing an effect in the width direction with respect to the crown setting of each stand at the time of rolling. CONSTITUTION:An optimum local curve making an effect small in the width direction of a crown Ci+1 at a stand with a small control capacity, is set from a rolling condition. By this setting, for a control range in the plate width direction when fixing local curve and rolling line load, it is understood that the control range of Ci+1 is small like that at the time of the roll profile of a sine curve, however, the effect in the width direction is small, too. In this case, since both of Ci+1 and Ci are constant in the width direction, a setable crown is not subject to the limit of a plate width. That is, the same crown is achieved in the whole width. Consequently, an achievable product crown range can be enlarged.
