Abstract: A sulfonic acid compound of a cyclic phenol sulfide represented by formula (1): (wherein X represents a hydrogen atom, a hydrocarbon group, or an acyl group; M represents a hydrogen atom, an alkyl group, a metal, ammonium, (lower-alkyl)ammonium, (lower-alkanol)ammonium, a nitrogen-containing heterocyclic group, or an amino acid residue; Z represents Sm, SO, or SO2; m is an integer of from 1 to 7; and n is an integer of from 4 to 12, with the proviso that the plural X's, M's and Z's are each the same or different, and at least one of the plural M's is neither a hydrogen atom nor an alkyl group), or a salt thereof; a composition for separating and recovering an organic halogen compound or a monocyclic aromatic compound, comprising a cyclic phenol sulfide or a salt thereof, and a carrier; and a pharmaceutical composition a cyclic phenol sulfide or a pharmaceutically acceptable salt, and a carrier.

Abstract: Improved transportation accuracy of a lead frame and reduced transportation time is attained. On the both sides of a heat block (1), rails (3a) equipped with a vertical drive mechanism are provided. By rotation of a screw shaft (7), a lead frame (4) is moved from front side to rear side of the heat block (1) along guide rails (3b) and the movable rails (3a) while holding the lead frame (4) by a clamp (5c) which has freedom of horizontal and vertical movements. During this transportation, a sensor (8) detects the position of the lead frame (4). A frame presser member (2) is mounted above the heat block (1) and equipped with a vertical drive mechanism for pressing the lead frame (4) against the heat block (1). The lead frame (4) is fed to a predetermined point by one motion of the clamp (5c) while firmly held by the clamp (5c) without frictionally contacting the heat block (1).

Abstract: A method for conveying a continuous semiconductor lead frame strip includes a guide rail for conveying a lead frame, the guide rail being divided into three portions having a vertically movable central guide rail portion opposite a heat block and fixed first and second guide rail portions on opposite sides of the central portion. The accuracy of conveyance of the strip is not decreased by the vertical movement of the central guide rail. Clamp claws grasping and conveying the strip at each fixed guide rail portion operate within the respective fixed guide rail portions and do not move vertically with the central guide rail.

Abstract: A lead frame conveying apparatus comprises a driving force converting unit for transmitting to a frame receiving arm a horizontal reciprocating linear motion of an elliptic motion of a timing belt place over two timing pulleys between the centers of the timing pulleys and converting semicircular motions at both ends of the horizontal reciprocating linear motion into vertical reciprocating linear motions by employing rolling contact for absorbing the horizontal component thereof and transmitting the vertical reciprocating linear motion to the frame receiving arm so as to put the frame receiving arm into a rectangular motion. The apparatus thus requires only one induction motor as a driving device.

Abstract: A device for forwarding semiconductor lead frames to a heater unit having a fixed heater surface. The lead frame is clamped and lifted by a predetermined height by a pair of clamp lifters and forwarded by linear motion guides on which the clamp lifters are mounted. Each clamp lifter includes upper and lower jaws, a cam mechanism including a vertically sliding horizontal rail, a lower jaw holder vertically slidably mounted on a linear motion guide, a support block vertically slidably mounted on the linear motion guide, and an upper jaw holder rotatably mounted to the support block. The cam mechanism varies the height of the sliding rail to three distinct levels, and thus effects the clamping and lifting operations of the clamp lifter.

Abstract: A semi-full cut semiconductor wafer is put on an adhesive sheet attached to a ring frame. Then, the semiconductor wafer is pushed upward from the back surface of the adhesive sheet by a rotatable breaking member in the shape of a disk the edge portion of which is triangular in section. In this state, the ring frame is moved so that the breaking member may not deviate from dicing lines, whereby the semiconductor wafer is divided into a large number of chips.
