摘要： PROBLEM TO BE SOLVED: To measure viscosity with high accuracy by detecting the rotary load of a viscous liquid received by the spindle suspended from the lower end of an output shaft on the basis of the piano wire twist quantity of a torsion bar. SOLUTION: A spindle 54 is immersed in a viscous liquid and a motor 33 is driven to rotate an output shaft 35 to rotate a screw shaft 39 and a gradations plate 43. The indicator support cylinder 44 and spindle 54 suspended through a piano wire 40 are ready to rotate so as to follow the rotation of the output shaft 35 but, since the impeller of the spindle 54 is immersed in the viscous liquid, the support cylinder 44 is rotated later than the shaft 39 by the twist action of the piano wire 40 so as to follow the rotation of the output shaft 40. This delay quantity is shown by the relative positional relation between the gradations plate 43 and an indicator 47. Herein, when a push member 56 is pushed down, the scale plate 43 is drawn up by a lever 57 to be integrally connected to the indicator 47. At this time, if the driving of the motor 33 is stopped, the viscosity of the viscous liquid is read from the positional relation of the scale plate 43 and the indicator 47. By this constitution, the mechanical friction resistance on the side of the spindle 54 is not generated and viscosity can be measured with high accuracy.

摘要： PROBLEM TO BE SOLVED: To improve the replacement workability of a spindle and fit or remove the spindle without applying bending force to an output shaft by screwing a one-operation coupler capable of fitting or removing the spindle via the fitting/ removing action in the direction parallel with the axial direction of the output shaft to a screw at the tip of the output shaft of a viscometer. SOLUTION: A base member 26 of a one operation coupler 24 is screwed to a left make screw 23 provided at the tip of the output shaft 22 of a viscometer 21, and the coupler 24 is connected to the output shaft 22. The outer circular sleeve 33 of the coupler 24 is moved toward the base member 26 against the elastic force of a spring 31, and the pressing of a steel ball 30 by the sleeve 33 is released. One of multiple spindles is selected, and the selected spindle 34 is inserted into a sleeve 28. When the insertion is completed, the sleeve 33 is recovered by the elastic force of the spring 31, the steel ball 30 is intruded into a steel ball intrusion recess 35 of the spindle 34, and the coupler 24 and the spindle 34 are connected together.

摘要： PURPOSE:To prevent the concurrent turn of a bolt with a nut by providing the end of the bolt with a reaction receiving section extending along a bolt axial line and having an outer diameter less than a bolt thread diameter. CONSTITUTION:A hexagonal bolt head 15 is formed on one end of a bolt 14, and a reaction receiving section 16 having an outer diameter phiA smaller than the thread diameter phiB of the bolt 14 is extended from a bolt end at the opposite side along the same line as the axial line thereof. The external surface of the section 16 is formed, for example, into a double hexagonal type, a hexagonal type or spline type, thereby preventing the occurrence of a slip relative to a spanner or the like catching the section 16. Then, the bolt 14 is inserted in the bolt holes 13 of tightened members 11 and 12, and a nut 17 is tightened. In this case, a tool such as a spanner is made to gear with the section 16 for preventing the concurrent turn of the bolt 14. As a result, a tightening work can be undertaken unidirectionally with the bolt and nut, thereby enhancing workability for screw tightening and ensuring a stable screw tightening work.

摘要： PURPOSE:To surely carry out imprinting independently of the dimension of the projection length of a screw from a nut which completes tightening, by installing a lever device which can press down a leaf spring for the urging of the rise of a printing rod, by the action of a toggle link in a pipe. CONSTITUTION:When the tightening torque due to a wrench 1 reaches a certain value, a toggle link 9 in a tilt state is turned in the axis line direction of a pipe 7 by the toggle action of the toggle link 9, and the projection formed on a lever 1b is pressed upward. Owing to the displacement of the toggle link 9, also the lever 1b is shifted, and a lever 14 is turned in the clockwise direction through a bolt 15, and a leaf spring 8 is pressed down. Accordingly, a printing rod is lowered sharply, and performs printing at the end part of the bolt. Accordingly, when tightening completes, the end part of the bolt can be imprinted and colored automatically.

摘要： PURPOSE:To reduce weight and improve shock resistance and abrasion resistance by fitting and fixing a pipe made of fiber-reinforced resin on the inside of a metal pipe whose surface is hardening and strengthening-treated. CONSTITUTION:A lightweight pipe 1 is constituted of a surface treated metal pipe 2 and a fiber-reinforced resin pipe 3, and the surface hardness of the metal pipe 2 consisting of a low carbon steel pipe is increased to Hv 150-180 in the Vickers hardness difference from the center part of the thickness of the pipe by heat, gas, etc. The resin pipe 3 is hardening-formed to a pipe shape by treating carbon fiber, glass fiber, etc., by the thermosetting type resin such as epoxy resin and phenol resin, or the thermoplastic resin such as nylon resin and polyethylene resin. The resin pipe 3 is fitted on the inner peripheral surface of the metal pipe 2, and attached by an attached sheet made of the thermoplastic resin, thermosetting resin, or epoxy resin contained in the pipe 3 itself, and the pipes 2 and 3 are joined by pressurizing and heating the inside of the resin pipe 3. Accordingly, the static strength of the pipe surface, fatigue strength, shock resistance and abrasion resistance can be improved.

摘要： PURPOSE:To make highly accurate screw fastening possible by providing a control circuit to make an electric motor function through a detecting signal corresponding to change in a load state. CONSTITUTION:Only a high speed electric motor 1 is first driven to rotate a driver bit 4 at high speed, and a screw is thereby quickly fastened up to its seated point. Next, when the current of the motor 1 increases or its number of revolutions decreases at the same time as the screw has attained its seated point, a detecting conversion circuit 12 issues an electric signal to actuate an electronic control circuit 13, and a low speed electric motor 2 is thereby started. At this time, both the motors 1, 2 function interlockingly to make regular screw fastening by large torque. When the fastening torque attains set torque, a toggle mechanism 6 functions to turn on a microswitch 8, and this turning on signal causes the quick brake stopping function of the electronic control circuit 13 to come into play for stopping both the moters 1, 2. Thus the screw fastening has been completed.
