Filed: 1992-03-31
Abstract: PURPOSE:To prevent a body from being exposed outside when plastic is poured into molds, by setting a salient section in contact with the body in the internal section of the mold to hold the body through the hole of a snap. CONSTITUTION:Salient sections 22 for holding a body 18 in direct contact with upper and lower molds 15, 16 are arranged. The salient sections 22 have horizontally long shapes for displaying function for holding the body sufficiently. When the long channel 11 of a tape snap 10 molded by the salient sections 22 is too long, possibility for lowering the strength of flanges 13 may be found. Accordingly, recessed sections 24 are arranged on the centers of the salient sections 22 so that bridges 12 for reinforcing the strength of the flanges 13 on the centers of the long channels 11 may be formed. The bridges 12 to be molded in this case are to have function for holding the body at the time of molding, and so the bridges are made thinner than the flanges 13. The body 18 with a hole 17 bored through is placed between the upper mold 15 and the lower mold 16, and after that, when plastic is poured from the inflow port 20 of the lower mold 16, the movement of the tip 19 of the body can be suppressed on a level equal to or lower than the upper surface of the bridge 12.

Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To provide an elevator device which is of a type sufficiently thin to enter a hoistway and has a simple structure by using a motor of radial gap type, formed with the gap between a stator and a rotor in the radial direction, and winding all stator coils around one tooth respectively, without extending over two teeth. SOLUTION: A motor (number of poles: 30 to 50) is of radial gap type formed with a gap between a stator 6 and a rotor 17 in the radial direction and is provided with all stator coils 5 wound around one tooth 18 respectively without extending over two teeth 18, that is, wound concentratedly. Winding a coil concentratedly can reduce the number of slots. In the case of concentrated winding, a combination of the number of poles and slots used most commonly has a ratio of the number M of the teeth to the number P of poles, P:M=2:3 or 4:3, if the teeth 18 and magnets are arranged at equal intervals. It is thus possible to reduce the number of slots to 4/3 at the most for a motor with multiple poles.
