摘要： PURPOSE:To make it possible to mold a stable high quality molded product by achieving the stabilization of metering and a plasticized state, by supplying the material in a hopper into a heating cylinder while rotating the feed screw in the hopper in synchronous relation to the screw in the heating cylinder. CONSTITUTION:The metering of the material 7 thrown in a hopper main body 16 is started by a screw 13 rotated by driving an electromotor 14 by the metering start signal from an injection molding machine. At this time, the electromotor 27 of a material supply hopper 15 is similarly driven as the electromotor 14 by the metering start signal from the injection molding machine and a feed screw 18 is rotated through a speed reducer 35. The material transfer capacity of the feed screw 18 is set so as to be made larger than that of the screw 13 and the amount of the material can be regulated in a stepless state by changing the rotation number of the electric motor 27.

摘要： PURPOSE:To prevent generation of oil leakage caused by cracks of an armature, and to contrive reduction in manufacturing cost by a method wherein the armature is formed by conducting an upsetting work on a soft steel wire material in which the content of phosphors and sulfur and the ferrite particle size of metal texture are specifically prescribed. CONSTITUTION:A plunger 7 and a compression spring 8 are housed in a cylinder 6 which is formed by drawing brass, and silicon oil is filled up therein. The aperture part of the cylinder 6 is closed by the armature 9 consisting of the large-diameter part 9a, which is brought into contact with the flange 6a of the cylinder 6, and a small-diameter part 9b which is fitted to a body part 6b. The above-mentioned armature 9 is formed by conducting an upsetting work on the soft steel wire material having the content of phosphorus and sulfur of 0.1wt.% respectively, and also having the ferrite particle size of metal texture of 7 to 8. As a result, the oil leakage caused by the cracks of the armature can be eliminated, the working manhours of the armature can be reduced, and the reduction in cost of an oil dashpot can also be achieved.

摘要： PURPOSE:To combine a die cloth cutting machine and a welder organically by irradiating the superposed part of core sheets with laser light from laser machining heads disposed at a plurality of positions at a timing for pressing the laminate of core sheets thereby welding the core sheets. CONSTITUTION:A core material, i.e., a hoop material 2 of thin steel plate, is fed automatically to a die cloth cutting machine 1 through an automatic reel 3. It is then fed through slit punching, face punching, and outer diametral punching steps to produce core sheets 4 having predetermined profile which are pushed sequentially into a core guide 5 where they are held in laminated state by the side pressure. When the core guide 5 is filled with the laminate of core sheets 4, the core sheets 4 are irradiated, on the peripheral surface, with laser light emitted from laser machining heads 6 in synchronism with the operation of the die cloth cutting machine 1.

摘要： PURPOSE:To enhance the coercive force during the exciting process by smoothing contact surfaces for reducing cavities by a method wherein the contact surfaces of an electromagnetic iron core mechanically polished is further chemically ground using a mixed solution containing phosphoric acid. CONSTITUTION:When an electromagnetic iron core composed of a movable iron core 1 and a fixed iron core 2 is mechanically polished, numerous rugged parts as the ground traces are left on the contact surfaces forming large cavities 4. When such an electromagnetic iron core is immersed in a mixed solution containing phosphoric acid melted in methanol with ethylene chloride added thereto and then heated, the rugged parts on the contact surfaces are further chemically ground by the phosphoric acid. At this time, the recessed parts are hardly effused but the projected parts are selectively effused so that the contact surfaces may be smoothed to reduce the cavities 4 between the contact surfaces. Through these procedures, the contact surface of the electromagnetic iron core mechanically polished are further chemical-ground so that the cavities between the contact surfaces may be reduced to enhance the coercive force during the exciting process.

摘要： PURPOSE:To take out and carry a fine wire coil without deformation and damage by making a nozzle suck a coil part after one of the lead parts of the coil formed on a core metal is clamped by a chuck means and carried to the nozzle position, and move the coil to a desired position. CONSTITUTION:A cam 28b is driven ahead by an actuator 32, a drive mechanism 28 closes a claw part 14 mounted on a shaft 22 against the force of a spring mechanism 26 and then the lead part of a coil formed on a core metal is held. The coil is moved in the direction where it is pulled off from the core metal and is taken out by a mover. The coil is then moved by a slider 12 to the position where it is sucked by a suction nozzle. A holding part 24 is driven back and opened by an actuator 32 and releases the lead part, then the coil 2 is sucked by the nozzle 70. The holding part 24 is moved to the position where the slider 12 is not prevented from being driven, so that the coil sucked and held can be moved to a desired position by the mover.
