Title: Darius wind mill
Inventor: NAKANO HIROAKI
IPC: F03D3/06
Filed: 1981-01-09
Abstract: PURPOSE: To increase rotatory torque of wind mill and improve characteristics of power output by a method wherein a variable mechanism of the blade fixing attack angle of Darius wind mill's blade against direction of wind may be held at its optimum each time.  
     CONSTITUTION: An angle of attack obtained by Darius wind mill's blade 1 against a uniform air current V 0  is to be constituted so that reciprocal speed W during one rotation of vane wheel and a torque changeable with variation of angle of attack α are set at the optimum. Therefore, a blade ring 3 connected with a blade 1 is variable to the direction α 0  by a pitch ring 6 through the intermediary of pitch arm 5, and lift force and resisting force occurred on the blade 1 are conveyed to a rotary shaft 2 through a stay 4. Thus energy of the wind is converted to energy to rotate the rotary shaft 2 by the wind mill, and the blade fixing angle is made variable arbitrarily by up and down motion of the pitch ring 6. Efficiency of the wind mill can be improved as compared with the case that angle of attack of the blade is fixed because a torque of the wind mill is balanced with the angle of the blade 1 during its rotation.

Title: Axial force detector for screw link tightening means
Inventor: NOJIMA SHUICHI
IPC: G01L5/00
Filed: 1989-01-09
Abstract: PURPOSE:To enable improvement in detection sensitivity and accuracy of an axial force by detecting the axial force loaded on a shaft-shaped section with a tightening of a screw linking means with a strain gauge. CONSTITUTION:When flange sections 5 and 6 are tightened by turning a nut 4, a tension works on a shaft section 1 downward in the drawing and a axial force introducing section 2 receives an axial force. As a support part 8 is supported with the flange section 6, the axial force introducing section 2 alone is displaced downward eventually causing a strain gauge section 2 to deform. That is, in the deformation, strain gauges 10 and 13 on the side of a top surface 7a and strain gauges 15 and 16 on the side of an undersurface 7b extend while strain gauges 110 and 12 on the side of the top surface 7a and strain gauges 14 and 17 on the side of the underside 7b contract separately. Then, in the strain gauges 10-17, the contraction thereof means a decrease in a resistance value and the extension means an increase in the resistance value. Thus, an axial force can be detected by a deformation of the strain gauge section 7.

Title: Remelting hardening treatment and device therefor
Inventor: KUSUKI HIROAKI
IPC: F16H53/02
Filed: 1992-01-08
Abstract: PURPOSE:To provide the remelting hardening treatment method which can melt and harden the metallic structure of the outer peripheral surface of a cam to be subjected to the remelting hardening treatment uniformly over the entire region in the circumferential direction of the outer peripheral surface. CONSTITUTION:The moving width of the relative reciprocating movement in the parts (M3 to M4) to be subjected to the remelting hardening treatment later than the vertex of the cam 2 near this vertex of the outer peripheral surface 5 of the cam 3 is set narrower than the moving width in the other outer peripheral surface parts (M1 to M3, M4 to M2). The melting temp. rises higher in the above-mentioned outer peripheral surface parts (M3 to M4) than in the other outer peripheral surface parts (M1 to M3, M4 to M2) and the shear droop at the shoulder is liable to arise when the relative reciprocating movement of the cam 2 and the torch 40 is so set as to be executed over the entire region of the cam width, but the shear droop at the shoulder is prevented by setting the moving width of the relative reciprocating movement in the part where the shear droop at the shoulder is liable to arise narrower than the moving width in the other outer peripheral surface parts.

Title: Liquid crystal display element
Inventor: YAMAGUCHI MASAHIKO
IPC: G02F1/1368
Filed: 1995-01-09
Abstract: PURPOSE: To improve a display grade by suppressing the dependency on a visual field angle. CONSTITUTION: This liquid crystal display element has a first electrode 22 having plural pieces of parallel wire-shaped electrode parts 18 formed on one substrate 16, a second electrode 28 having plural pieces of parallel wire-shaped electrode parts arranged between the respective wire-shaped electrode parts and a switching element 30. The pretilt angle of oriented films is <=3 deg. and the orientation direction γ of the oriented films and the longitudinal direction of the wire-shaped electrode parts are parallel. An inter-electrode spacing G and the spacing D between both substrates satisfy the following equation: 0.5<=G/D<=3.0.  Then, this element is not of a type to erect or lay liquid crystals by a change in electric fields and, therefore, the degradation in transmittance by a difference in the refractive index between the major axis direction and minor axis direction of the liquid crystals hardly arises. The dependency on the visual field angle is thus suppressed and the display grade is improved.

Filed: 1979-01-16
Abstract: PURPOSE:To let relatively small molten metal influent speed be readily obtained by estabilishing the specified conditions between the inside diameter of a tundish nozzle and the inside diameters of the bottom and top end part of a pouring nozzle and forming the both nozzles into the hermetic construction to the atmosphere. CONSTITUTION:With the molten metal in a tundish 10 being maintained at the height h1 from the bottom end of a tundish nozzle 14, the molten metal 12 is flowed out through the nozzle 14 and pouring nozzle 16 into a mold 18. The molten metal 12 is subsequently cooled to become a slab 22 which is then pulled by pinch rolls 20. If here the inside diameter d1 of the nozzle 14, the inside diameter d2 of the bottom end of the pouring nozzle and the inside diameter dM of the top end of the pouring nozzle are so constituted as to satisfy the two relations of dM>d2>=d1>15mm, 5d1>=dM>1.2d1, then the effluence rate from the bottom end of the nozzle 16 may be made fairly smaller than the anticipated rate of flow under the height up to the molten level in the tundish 10 from the bottom end of the pouring nozzle 16. Because of this, the remelting of the solidified shell and the capturing of non-metallic inclusions into the solidified shell become difficult to occur.
