Title: Method for preparing nucleic acid fragment
Inventor: NAKANO TAKAMORI
IPC: C12Q1/68
Filed: 1986-02-07
Abstract: PURPOSE:To form a nucleic acid fragment at high concn., by elongating the nucleic acid fragment in a reaction liquid containing no dideoxynucleotide and subsequently stopping the elongation of the nucleic acid fragment in the reaction liquid containing dideoxynucleotide. CONSTITUTION:In a first stage, all of nucleic acid fragments continue elongation because no dideoxynucleotide is contained and, in a second state, the elongation is stopped at the point of time when dideoxynucleotide was taken in the nucleic acid fragments having continued elongation. By enhancing the ratio of the quantity of dideoxynucleotide to deoxynucleotide in a reaction liquid in the second stage as compared with that of a conventional method, the elongation reaction of almost all of nucleic acid fragments can be stopped during the second stage. As a result, a short nucleic acid fragment or a long nucleic acid fragment no coming to an object to be detected is not contained or is contained at low concn. and a specimen containing a nucleic acid fragment having a length coming to an object to be detected is obtained.

Title: Semiconductor circuit device
Inventor: AKIYAMA NOBORU
IPC: H03K19/0944
Filed: 1989-02-03
Abstract: PURPOSE:To miniaturize a MOS transistor and to attain fast and low power consumption by setting the highest voltages to be applied on a BiCMOS logic circuit and between the source and drain of the MOS transistor comprising the CMOS logic circuit less than a source voltage, and also, setting all of them at the same level. CONSTITUTION:When an input voltage goes to a high level and a load charging bipolar transistor(BTR) 13 is turned off, the MOS TR 15 is turned on, and the voltage at the base terminal of the BTR 13 goes to (VBE). The drain terminal of the MOS TR 11 is connected to the base terminal of the TR 13, and the voltage at the drain terminal of the MOS TR 11 goes to VBE. Since the source voltage VCC is applied on the source terminal, the voltage less by VBE than the source voltage VCC is applied between the source and drain of the MOS TR 11. When the input voltage goes to a low level and the BTR 13 is turned on, the output voltage goes to a value VCC-VBE less by the base/emitter forward directional voltage V of the BTR 13 than the source voltage VCC.

The new center point position O'' of the wafer is present on the line OR'. The handler 4 is rotated together with the wafer 3 only by theta to bring the direction OR' in accordance with the reference direction OQ. The center point position moves to a point O''' on the line OQ. As the handler 4 has been slipped in reverse direction by theta, a rotary unit 12 rotates only the handler 4 reversely only by angle theta.
