摘要： PURPOSE:To perform a stable printing operation by enabling magnetic interference which is to be generated between leakage magnetic flux from a coil and magnetic flux of a permanent magnet to be prevented even though the printing operation is performed at a high speed. CONSTITUTION:An armature 11 is arranged opposed to a core 2 on which a coil 3 is wound around. A printing wire 5 is fitted to one end side of the armature 11 via a lever 4. Magnetic flux of a permanent magnet around the core 2 is offset by making a current flow to the coil, and the armature 11 is driven to print with the printing wire 5. The armature 11 is molded by metal powder injection molding. Further, an absorbing surface 11A of the armature 11 is molded in the almost same form as an absorbing surface 2A of the core 2.

摘要： PURPOSE:To reduce the printing noise of a wire dot printer while holding the operation of the printer, that is, user's convenience to a good state as before by applying a soundproof measure in close vicinity to a noise generating part, noticing the vicinity of a printing head being a printing noise generating source. CONSTITUTION:By bringing the cover 35 mounted on a printing head into contact with an object 7 to be printed, the vibration of the object 7 to be printed can be suppressed in the vicinity of an impact point and the noise generated by the vibration of the object 7 to be printed is reduced. Or, by bringing the object 7 to be printed into contact with the elastomer 37 inside the cover 35, the close contact of the object 7 to be printed with the printing head is enhanced and attenuation effect can be also provided. By this method, the vibration of the object 7 to be printed is suppressed elastically or by attenuation to reduce printing noise.

摘要： PURPOSE:To perform the quick input of data with labor saving by storing temporarily the preceding transaction data to read it out in the next transaction mode and displaying this data on a transaction screen as a new data. CONSTITUTION:The transaction data is supplied to the transaction screen of a display device 4 by means of the ten keys 6 and the input key 7 of a control panel 3. Then an input end key 9 is depressed and a CPU 1 decides the prescribed conditions and fetches the transaction data displayed on the transaction screen to a memory 2 if the decided conditions are satisfactory. Then the CPU 1 sends the editing data to a host station 5. In case the input data on the preceding transaction is used as it is when the data on the next transaction is supplied, the CPU 1 decides the desired conditions with the depression of an induction input key 8. If these conditions are satisfactory, the input data on the preceding transaction is displayed on the input field of the corresponding present transaction. Thus the input data can be easily reused. This improves greatly the input operation of data.

摘要： PURPOSE:To reduce the damage, vibration and noise of a gear by avoiding a resonance of the rotating pulsation of an induction motor driven by a frequency converter controlled by PAM system with the gear engagement of a reduction gear. CONSTITUTION:In a drive device of an elevator, the engaging basic frequency fgo of a gear is so set as to become a range of a formula in such a manner that the frequency 6if10 of a rotating pulsation generated in a motor 4 does not coincide with the frequency fgo of the gear, where f10 is the output basic frequency of a frequency converter and (i) is the number of orders 1, 2, 3,... at input shaft 11, intermediate shaft 13 and output shaft 16 of a reduction gear 5. Thus, the resonance of the rotating pulsation of a motor 4 with the engagement of the gear is avoided to reduce the damage, vibration and noise of the gear.

摘要： PURPOSE:To provide an apparatus for stopping the cage of an elevator immediately when it is at an abnormal high speed, the construction of the apparatus being simplified and the workability and reliability of it also being improved. CONSTITUTION:A governor rope 7 generally moves at the same speed as that of the cage. However, when the cage has descended at an abnormal high speed due to some reason, a governor (not shown) is actuated to terminate the movement of the governer rope 7. In this case as the cage tends to descend further due to its weight, a lever 20 one end of which is anchored to the rope 7 by a rope stopper 6 is forced to move to a position shown in phantom line, a lifting rod 21 is lifted, and a lifting rod 30 is also lifted through a shaft 18 and a lever 29. Then, bumpers 31, 32 below the respective rods serve to operate bumper portions 34, 35 provided on a vertical frame 33 of the cage, and by the action of a cage stopping apparatus of an emergency stop apparatus (not shown) the cage can be locked to the guide rail to be stopped immediately.

摘要： PURPOSE:To provide a stable and precise overspeed detection performance by fitting a damping element in one of the bosses of a governor pulley and a pendulum receiver and enabling adjustment of the elastic force of the element. CONSTITUTION:A damping element 25 is fitted in one of the bosses of a governor pulley 1 and a pendulum receiver 8, and the elastic push force is made ajustable. The pulley 1 and the pendulum receiver 8 rotatably supported on a shaft 7 are elastically engaged through a vibration shield spring 11, and a pendulum 16 is rotatably supported on the shaft 15 of the pendulum receiver 8. A flange-like damping plate 24 is fixed on a side face of the boss of the pulley 1; a damping element 25 is supported by a rod 27 to face the plate 24 and is pushed toward the plate 24 by the elasticity of a coil spring 31 adjustable by the rod 27. Thus the elasticity of the spring 31 is made larger and adjustable so as to facilitate the setting of frictional force and to provide stable overspeed detection performance.
