Abstract: A linear compressor according to the invention is for generating compressed gas and includes two pairs of pistons 608a, 608b and cylinders 607a and 607b coaxially provided and facing opposite to each other, a shaft 603 having pistons 608a and 608b at its ends, coil springs 605a and 605b coupled to shaft 603 for returning a piston departed from a neutral point to the neutral point, and a linear motor 613 for causing shaft 603 to axially move back and forth, thereby generating compressed gas alternately in two compression chambers 611a and 611b. Thus, the non-linear force of the compressed gas acting upon the pistons may be divided into two/reversed in phase. As a result, as compared to a conventional structure having only a single piston, the motor thrust may be reduced and linearized for the purpose of improving the efficiency. Furthermore, the size of the device may be reduced as well as the vibration/noises caused thereby may be reduced.

Pad support members are slidably mounted on the slide shafts. Suction pads for holding the package portions with suction are mounted on respective pad support members. The sliding of the slide members is limited by a slide limiting device on the frame conveyor plate. The slide limit of the pad support members is removed by a pad moving mechanism and the pad support members are moved along the slide shafts. Information regarding the lead frames is input into a controlling section so that the pad moving mechanism can be controlled and the positions of all the pad support members automatically adjusted.

Abstract: In a laser marking apparatus, a rotatable index table is provided in an index unit. The index table is provided with first and second support sections for supporting lead frames. Positions of the first and second sections are alternately switched between a stand-by position and a processing position by the rotation of the index table. Laser marking is subjected to IC package surfaces of the lead frame supported at the support potions located at the processing position. The lead frames after the laser marking process are transported from the stand-by position to a discharging section by a transporting device. The lead frames before the laser marking process are transported from a supplying section to the stand-by position by the transporting device.

Abstract: In a linear compressor driving apparatus, a position instructing portion (31) outputs a position instruction value Pref of a piston in accordance with an equation A*sin .omega.t. A position control portion (33) calculates a speed instruction value Vref by multiplying difference between position instruction value Pref and position present value Pnow by a constant Gv. A speed control portion (35) calculates a current instruction value Iref by multiplying a difference between speed instruction value Vref and speed present value Vnow by a constant Gi. A current control portion (37) controls a power source (3) so that current present value Inow becomes equal to the current instruction value Iref. Phase control portion (38) adjusts .omega. and Gi so as to eliminate phase difference between speed present value Vnow and current instruction value Iref. Since thrust of linear motor can be directly and appropriately controlled in accordance with the load condition, high efficiency is obtained.
