Abstract: A wafer transfer method for forming a second work unit by transferring a wafer of a first work unit including a first ring frame, a first adhesive tape, and the wafer to a second adhesive tape includes sandwiching a claw body between the first ring frame and a second ring frame, affixing the second adhesive tape to a surface of the wafer which surface is not affixed to the first adhesive tape, holding the wafer by the second ring frame via the second adhesive tape, and peeling off the first adhesive tape from the wafer.

Abstract: Sustained release micropellets showing a stable controlled-release of a drug without being affected by the changes in pH value etc., characterized by being produced by coating core particles with a layer containing a water-soluble drug and further forming a film layer containing a water-insoluble polymer compound and a plasticizer on the thus obtained particles, locating a water-soluble filler layer between the water soluble drug-containing layer and the film layer, and having an average particle size of 300 ?m or less; medicinal compositions containing these micropellets; and a process for producing the same.

Abstract: A coating apparatus comprises a high speed camera for imaging a tablet layer in a rotating drum, personal computer for calculating a flow rate of a tablet in the tablet layer based on image data from the high speed camera, and a control apparatus for controlling a rotational speed of the rotating drum based on a calculation value of the flow rate of the tablet obtained by the personal computer.

Abstract: An inertia latch mechanism has a latch arm, which latches a head actuator in a retreated position, and an inertia arm, which is rockably supported around a second pivot and rotates the latch arm to a latch position by rotating around the second pivot when subjected to an external force. A voice coil motor has a lower yoke, a top yoke, a voice coil attached to the head actuator and situated between the yokes, and a permanent magnet provided on at least one of the yokes. The top yoke has an arm retaining portion which extends overlapping the second pivot and that part of the inertia arm which is situated near the second pivot and restrains the inertia arm from slipping off the second pivot. The arm retaining portion is stepped to be one level higher than the top yoke.
