摘要： PURPOSE:To prevent any possible damage to an apparatus such as an electromagnet or the like due to such that this magnet is forcibly pressed to the work as well as to keep off the shortening of working time for taking out the work at a time when each work different in weight is lifted up. CONSTITUTION:Compressive force and tensile force to be added to two electromagnets 6 are detected each by two load cells 7 and thereby when the compressive force being added to these two electromagnets 6 is increased more than the setting value, the down control of these electromagnets 6 by a vertical mobile mechanism 3 is stopped and these electromagnets 6 is prevented from being pressed to a work more than this extent. In addition, when the tensile force to be added to these two electromagnets 6 is increased as far as more than the setting value, current-energization to these two electromagnets 6 is stopped, whereby such a possibility that more than two pieces of the work 5 might be attracted to these two electromagnets 6 is prevented from occurring. In this constitution, this lifting gear is able to quickly correspond to the work 5 different in weight by way of altering the setting value of the tensile force by a tensile value setting switch 29.

摘要： PURPOSE:To simplify the processing of a lead wire of a voice coil by fitting a ring shaped relay band whose terminal pin is fitted with a colored wire to a bobbin. CONSTITUTION:A curing layer 1a is formed to the surface of a bobbin 1, the bobbin 1 is fitted to a jig 3, a 1st layer of a lead wire in the coil 2 is wound from the lower end of the bobbin 1 by a prescribed number of turns, a 2nd layer is wound on the 1st layer and a part of the end is wound on the bobbin 1 to form a winding part and the winding part is fixed with adhesives. Then a ring shaped relay band whose terminal pin projecting in a proper position of the outer circumference is fitted with the colored wire 8 is fitted to the bobbin 1 and the lead wire of the winding is welded to the terminal pin 6. Thus, the connection processing of the leadout wire of the voice coil is facilitated and the operability is improved.

摘要： PURPOSE:To automatically execute leveling in a short time by providing a light emitting means formed in a pendulum and a sensing device provided with a horizontal coordinate provided with a light receiving means on every block on a pedestal part side. CONSTITUTION:In a pedestal part 5 of a survey instrument supported through three pieces of height adjusting screws 3a - 3c on a supporting board 1 of the upper end of a tripod, a light emitting means formed in a pendulum 16 and a sensing device 11 in which a horizontal coordinate 17 provided with a light receiving means on every block is provided right under the light emitting means are provided on the pedestal part side, at least two pieces among three pieces height adjusting screws 3a - 3c can be turned by a motor, and driving of the motor is controlled by an output of the sensing device 11. At the time of using by extending the tripod and adjusting the length of the tripod, the supporting board 1 is set to desired height. In the sensing device 11, a laser light emitted from a semiconductor 18 is condensed by a collimating lens 19 and reaches the horizontal coordinate 17, and detected by a photodiode 22. In such a way, leveling can be executed automatically in a short time.

摘要： PURPOSE:To facilitate the assembly of the titled cooler for cooling oils and enhance the cooling effect and function of the cooler by a method wherein oil-passing holes and cut-and-erected pieces are provided on a fin plate 26 of a cooling pipe of the cooler, and the oil being passed is deflected by the pieces to flow along the fin surface. CONSTITUTION:The fin plate 26 provided for the cooling pipe 25 is provided with slot-shaped oil-passing holes 28 and with the cut-and-erected pieces 29 which project on one side of the plate 26. Further, an opening 30 directed along the surface of the plate 26 is provided between each of the pieces 29 and the plate 26. Accordingly, the oil introduced into the cooler passes the holes 28, impinges upon the pieces 29, whereby deflected to flow along the surface of the plate 26, and flows through the openings 30 toward the oil-passing holes 28 of the next plate 26. Accordingly, the contact between the oil and the cooling-pipe wall surfaces is improved, so that the cooling effect and function of the cooler can be enhanced.

摘要： PURPOSE:To endurably located a port, by a method wherein a film of a polyethylene bag and a film-strip for a port, made of a similar material to that of the bag, are welded together by heating at an approximately central section thereof, and both sides of the film strip, which are risen upward after a hole is made at a center of the adhered portion, are welded together by heating at both edges thereof facing and positioned opposite to each other. CONSTITUTION:A film strip 2 for a port made of the same material as that of a bag film 1 is superposed on the bag film 1 made of a polyethylene material, the films 1 and 2 being welded together by heating at an approximately central portion of the film strip 2 for the port to form a welded portion. A hole 4 is made in the center of the welded portion 3 such that the fringe of the welded portion is left as it is. Both sides 2a and 2a', in the direction of a long side, of the film strip 2 for the port are risen upward for being superposed together, and simultaneously, both side edges thereof, facing and being positioned opposite to each other, are welded together by heating to form the port of the polyethylene bag.

摘要： PURPOSE:To generate a stable dust-collecting electric field, by laminating a surface- roughened anticorrosive plastic layer on a fiberglass-reinforced plastic layer. CONSTITUTION:An anticorrosive layer 2 is laminated on an FRP layer containing glass fiberglass 4 and is integrally shaped with the latter layer. Before the curing of the shaped layers is finished, a pressurizing member 3 whose surface is previously roughened into recesses and projections smaller than the thickness of the anticorrosive layer 2 is thrusted on the layer 2 to press it to roughen its surface. An atmosphere insulating film is preferable as the pressurizing member 3 if the FRP layer is shaped by a hand-lay-up method. The surface of one side of the atmosphere insulating film is roughened and then set in contact with the surface of the anticorrosive layer 2. The film and the layer 2 are thrusted on each other between a surface plate 5 and a press 6.
