Title: Manufacture of integrated circuit
Inventor: JIYAAN JIMAANE
IPC: H01L21/8249
Filed: 1990-06-01
Abstract: PURPOSE: To simultaneously make optimum an N channel MOS transistor and a vertical PNP bipolar transistor by inserting much doped source and drain regions into the same conductive type cup extending slightly more laterally below a gate. CONSTITUTION: After a MOS transistor gate 40 is formed, regions 53 to 56 where a first conductive type is move doped are injected and annealed into a position of a bipolar transistor excepting a portion where an emitter of the bipolar transistor is formed. Then, regions 61 to 63 where a second conductive type is more doped are injected and annealed at a position where the emitter of the bipolar transistor is desirably formed. There is left behind a part of a layer where the injection and annealing into the regions where the first and second conductive types are more doped are obtained as a result from low level injection of the first conductivity type under each of the foregoing regions. Accordingly, a MOS transistor having a first conductive type channel and a vertical bipolar transistor having the second conductivity type emitter and collector can be optimized.

Title: Centrifugal loading apparatus
Inventor: KAWASAKI KOJI
IPC: G01N3/00
Filed: 1989-06-12
Abstract: PURPOSE:To eliminate the strain in a centrifugal field due to the difference in positions of a sample by imparting reciprocating motion in the circumferential direction to a case for containing soil which is the test sample under test. CONSTITUTION:The direction of the reciprocating motion of a sample case 5 is made to agree with the turning locus of an arm 1. For this purpose, e.g. the bottom side of the sample case 5 and the facing surface of a swing basket 5 are formed as an arc surface 31 which is conformal to a circle with a vertical rotating shaft 2 of the arm 1 as the center when the sample case 5 is horizontally positioned. The sample is contained in a sample case 5 having said constitution. The case is turned at a high speed by the turning of the arm 1. The changing state of the sample at this time is picked up with a high speed camera. The properties of the structure of soil are analyzed in the process of said changes. At this time, centrifugal force is imparted to the sample case 5 by the rotation of turning of the arm 1. At the same time, vibrating force is applied in the circumferential direction. Thus the strain in he centrifugal field due to the difference in positions with respect to the sample in the case 5 can be eliminated.
