Filed: 1986-04-14
Abstract: PURPOSE:To use a brush holder jointly by arranging the brush holder on the inner circumferential surface of a frame body, given a turn around a shaft so as to be rotated around the longitudinal direction of the brush holder. CONSTITUTION:The directions of mounting of brush holders 4 are disposed so as to be approximately equalized along approximately the directions of movement of brushes 9, and the brush holders 4 on the right side shown in the figure are given a turn, rotated around the longitudinal direction, and arranged on the side-surface inner circumferential surface 57 of a base frame 24, thus resulting in mutual surface symmetry regarding the diametral direction in the left and right brush holders 4. Accordingly, the title fixture differs from conventional devices in which the brush holders are fitted to the opening end surfaces of yokes in the direction rectangular to the direction of movement of brushes, and only single parts may be used for the brush holders 4, thus jointly employing parts.

Title: Ink ribbon winder
Inventor: ISHIDA MASAHIRO
IPC: B41J33/36
Filed: 1981-06-03
Abstract: PURPOSE:To wind up an ink ribbon at an exact winding pitch without causing any loosening by using a system in which the action of a solenoid is transmitted through a one-way bearing to a drive roller and a spool, and the winding amount of the spool is made larger than that of the drive roller. CONSTITUTION:When a signal is put in a solenoid 17 and a plunger is attracted, a lever 19 is turned around a shaft 20 in the direction of arrow 63, and thereby arms 24 and 25 are also turned through an operating lever 23. The rotation force of the arms 24 and 25 is transmitted through one-way clutch bearings 34 and 35 to driving gears 38 and 39, and as the driving gear 38 turns, the driving roller 5 is turned at a given angle in the direction of arrow 40 to send a ribbon 2 at a given pitch in the direction of arrow 10. On the other hand, the rotation of the gear 39 is transmitted through a clutch gear 50 to the spool 4, and thereby the spool 4 turns with a slightly larger winding amount than that of the driving roller 5 to wind up the ribbon 2. The difference in the winding amount between the spool 4 and the driving roller 5 is eliminated by the drag of the clutch gear 50.

Title: Numerical control method
Inventor: IRIGUCHI KENJI
IPC: G05B19/4097
Filed: 1992-03-10
Abstract: PURPOSE:To evade interference between a part except the tip part of a tool and a work by making an interference check on inclusion sphere and tool shape data regarding curved surfaces of a curved surface model. CONSTITUTION:An NC device inputs the curved surface model as the three- dimensional curved surface shape of a machined element and generates a sphere SO including the whole curved surface FO. Then the curved surface FO is divided into partial curved surfaces F1-F4 to generate inclusion spheres S1-S4, and further the division and the generation of inclusion spheres are repeated until an inclusion sphere radius reaches a certain value. The initial sequence of contact points between the tool and curved surfaces is calculated. When one contact point is extracted from the calculated contact point sequence and virtually positioned, an inclusion sphere interfering with the tool is extracted. Then the group of points on curved surfaces that the extracted inclusion sphere includes is generated. When a point in the tool shape is present in a finally obtained point group as the result of generation processing, the NC device judges that the curved surface interferes with the tool shape at the contact point and moves the contact point.

Title: Method and apparatus for measuring hardness
Inventor: ONO MASAMITSU
IPC: G01N3/40
Filed: 1986-04-16
Abstract: PURPOSE:To measure the hardness of the peripheral wall of a center hole having a small inner diameter with high reliability, by inclining a hardness meter with respect to a measuring surface. CONSTITUTION:A hardness meter fixing apparatus 1 is arranged to the center hole 3 of a turbine rotor 4 in a manner movable to the longitudinal direction thereof. The apparatus 1 has wheels 5 and can be held so that the horizontal surface 1a thereof is inclined and the angle theta of inclination of the horizontal surface 1a is detected. The angle theta is displayed on an angle display device 7a through a cable 6a and inputted to an operation apparatus 9 by a cable 8a. Further, a hardness meter 2 is provided to the horizontal surface 1a and a pressure element is pressed to the peripheral wall 3 of the center hole under the constant pressure of a spring to form a cavity. When the pressure element is not brought into contact with the peripheral wall, vibration frequency is constant but changes during the penetration of the pressure element under pressure. If the peripheral wall 3 is soft, the cavity is large and the change in the frequency becomes large. The hardness meter 2 accurately detects the change in the frequency to display the same on a hardness display device 7b through a cable 6b. The apparatus 9 corrects the hardness of the angle theta on the basis of preliminarily calculated function to display true hardness on a digital hardness display device 10.

IPC: B65H23/038
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To detect and correct displacement in the longitudinal and latitudinal directions of a sheet material by arranging a driving control part controlling independently the respective driving motors of a friction ring acting on one edge part of the sheet material and a friction ring acting on the other edge part thereof. SOLUTION: When a bias error in a width direction accompanied by movement in the longitudinal direction of a sheet material 12 is detected, a second sensor 58 outputs a signal to a driving control part and corrects the position of the sheet material 12 by correction action so that the covered area and exposed area of the second sensor 58 become the same. This correction action is performed according to a direction where a bias error in the width direction is generated. While, if the feeding direction of the sheet material 12 is reversed, control regarding the bias error is changed by the driving control part from the second sensor 58 to a first sensor 56 being a rear side in the new feed direction in relation to a friction ring 34 or the like. The bias error can be detected and corrected by the first sensor 56.

Abstract: PURPOSE:To make easy and efficient control of flow rate of powdered substance which runs through a powdered substance pneumatic transportation pipe by providing a swirl generating mechanism having a bulge part in the way of the pipe and by regulating the pressure of jet flow which is blasted into the mechanism. CONSTITUTION:A swirl generating mechanism 5 having a large diameter bulge 7 is disposed in the way of a transportation pipe 6 running as one of branches into which a main tranportation pipe is divided by a distributor. The upper part of the bulge has a jet blasting nozzle 10 which opens in the tangential direction in relation to the internal perimeter wall of the cylindrical part thereof, while the lower part is communicated with a transportation pipe 9.
