Title: Method and apparatus for measurement of pulley load
Inventor: KAJIWARA KAZUHISA
IPC: G01L5/04
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To measure the state of a load required for designing a pulley at a time when a belt is running. SOLUTION: In this method, the state of a load applied to a pulley 12 is measured by using both loads applied in the tension-side winding tangent-line direction and the slack-side winding tangent-line direction of a belt 14 with reference to the pulley 12 at a time when the load applied to the pulley 12 on which the belt 14 is wound is measured, Then, the load applied to the pulley 12 is measured by using an equation which indicates that the moment difference between respective angular moments applied to the pulley 12 by the tension-side tension and the slack-side tension of the belt 14 is balanced with the moment difference between respective angular moments in respective load points corresponding to both loads and by using an equation which indicates that both tensions are equal to both loads.

Title: Oil seal device
Inventor: KOBAYASHI TADASHI
IPC: F16J15/16
Filed: 1982-07-28
Abstract: PURPOSE:To reduce oil leakage by selecting a bearing and a slinger seal at near positions in the axial direction so that the distance between them is kept an optimum value. CONSTITUTION:The length of the cylinder section 4 of a slinger seal 14 is shortened, and the distance E between the side surface 2A of a rolling bearing 2 and the facing surface of the flat plate section 4A of the slinger seal 4 is extremely reduced so that the E is kept within a range of 0.5<=E<=1.0mm.. 6 is an oil return passage provided below the flat plate section 4A. 20-40% of lubricating oil jet-injected through a nozzle 3 and sprayed to the bearing 2 passes through the bearing 2, but the liquid and mist-like lubricating oil is blocked by the flat plate section 4A and radiated in the radial direction of the bearing 2, then is returned to an oil reservoir through the oil return passage 6. Therefore, the flow direction is efficiently changed from the axial direction to the radial direction, thus the oil leakage is remarkably reduced.

Title: Drawing of stepped tube
Inventor: KANAI AKIRA
IPC: B21C1/22
Filed: 1977-10-31
Abstract: PURPOSE: To obtain stepped tube having excellent straightness and concentricity by the procedure in which a mandrel with plug is inserted into a tube whose overall length is finished to the dimension of largesized final product and then mandrel is advanced at the same speed as the drawing speed of tube by turning the plug face to face with the die hole.  
     CONSTITUTION: The contraction 1' is formed at the tip of the tube 1 drawn precisely to the dimension of large sized final product with respect to the whole length, the die 2 of small diameter dimensions is inserted into the contrection. The mandrel 3 fitted with the hollow plug 4 with the aid of the split ring 5 is inserted into the tube 1, and the hollow plug 4 is set in the face of the intromittent portion of the die hole 2. The contraction 1' is drawn by means of the clipper wheel 6 of the drawer and the mandrel 3 is advanced with the tube. In this case, the plug 4 slides around the outer periphery of the mandrel but serves as floating plug by a frictional force due to a wedge-wise action while keeping a normal position against the die 2. Thus, the center of the plug always coincides with the drawing center, thus giving a stepped tube having excellent straightness and concentricity.

Abstract: PURPOSE:To obtain a medium liquid for electrophoretic sepn. having reproducibility and good stability by maintaining the temp. at the time of mixing two kinds of thick and thin monomer liquids of continuously varied flow rate ratios and a polymn. reaction initiator liquid to prepare said medium liquid at a prescribed temp. CONSTITUTION:The medium liquid 12 for electrophoresis prepd. by stirring and mixing the low-concn. monomer liquid 1, the high-concn. monomer liquid 2 and the polymn. reaction initiator liquid 3 by means of a static mixer is passed by changing the flow rates of the low-/high-concn. monomer liquids 1, 2 continuously as shown in the figure. The stirring and mixing are executed at this time by passing cooling water in a jacket 24 provided as a sleeve of a housing 22 sealed with the elements 21 of the static mixer 21 thereby maintaining the temp. in the mixer within the temp. higher than the temp. at which the components in the medium liquid precipitate and lower than the temp. at which a gel-like material is produced. For example, the temp. is kept at 10-15 deg.C in the case of an acrylamide gel. Namely, the precipitation of the components in the medium liquid arises at <=10 deg.C and the gel-like material is produced at >=15 deg.C and, therefore, the medium liquid 12 is sent to a coating head without generating foreign matter in the above-mentioned temp. range. The coating liquid is thus produced with the high reproducibility.
