摘要： In a hybrid injection system of a die casting machine, the occurrence of a large electric power loss can be prevented by avoiding a large current at a pressure-holding step and the size of a motor is reduced.In an injection system comprising an injection cylinder (16) housing an injection piston (15) for injecting molten metal to a mold and an electric booster (8) of hydraulic cylinder type, a head chamber (8H) to the electric booster communicates fluidly with a head chamber (16H) of the injection cylinder, causing a booster piston rod (5) to be housed in the electric booster (8) to move linearly and thus pressing under pressure to move the injection piston to perform injection molding. Because a stop valve (25) is provided in a pipe that causes the head chamber (16H) of the injection cylinder to communicate with a rod chamber (8R) of the booster (8), it is possible for the pressure of the hydraulic oil to act on a head area of the electric booster at a pressure-increasing step for increasing pressure of the molten metal, and for pressure of the hydraulic oil to act on a rod area of the electric booster at a pressure-holding step for holding pressure of the molten metal.

摘要： In a pressure-casting method and apparatus, wherein a metal melt is fed in a mold cavity and then an oscillating squeeze pressure is applied to the melt by a squeezing plunger of a hydraulic cylinder moving with an oscillating stroke varying to compensate for shrinkage of the melt while being solidified, the hydraulic cylinder is feedback-controlled, using a control unit including a detector for detecting information on an actual squeeze pressure, so that a pressure converted from the actual oscillating squeeze pressure to have a mean value of zero copies a desired alternately positive and negative impulsive pressure pattern or locus representing a pressure oscillated to have a mean value of zero with a given amplitude and frequency versus an elapse of time.

摘要： A spool braking device for a dual bearing reel includes a spool brake unit, a spool control unit, and a tension detection unit that includes a rotational speed sensor. The spool control unit is arranged between a spool and a reel body, and it an electrically controllable unit that controls the spool. The tension detection unit detects the tension applied to fishing line that is released from the spool during casting. The spool control unit electrically controls the spool braking unit so that the spool braking unit brakes the spool with a first braking force of 50 to 100% of the maximum braking force during a first predetermined time period when the tension detected by the tension detection unit is at or below a first predetermined value.
