IPC: G01N27/447
Filed: 1990-04-27
Abstract: PURPOSE: To surely determine the absolute concentration of sample components by installing an apparatus which vacuum introduces a sample solution into a separation column. CONSTITUTION: Compliant pressure difference is so applied to a separation column 114 as to introduce a sample solution 104 into the separation column 114 during the time when an inlet end of the column 114 is in the sample solution 104. The characteristic of the pressure difference in reference to time is so selected as to introduce a desiring volume of the sample solution 114. That is, the pressure and the time to be taken for injection of the sample solution 104 are so controlled as to introduce the right volume of the sample solution 104 into the column head 144. The pressure and the time for that are controlled at sufficiently high precision as to give within 5%, preferably 1%, of the precision of measurement in the partial different conditions by the volume.  Moreover, the pressure difference is set to be sufficiently low and the time is set to be sufficiently long, so that proper allowable velocity for introduction of the sample solution 104 is provided.

Title: Method for high resolution processing for a/d converter
Inventor: TAJIMA MASAMI
IPC: H03M7/30
Filed: 1994-05-27
Abstract: PURPOSE:To attain high resolution processing for a A/D converter, and to attain miniaturization and low power consumption by applying A/D conversion to an input signal with a low resolution A/D converter, dividing the signal into a small range as an offset voltage, applying A/D conversion to a difference resulting from subtracting the offset voltage from the input signal with an accurate A/D converter and synthesizing them after A/D conversion. CONSTITUTION:All levels of an input signal IN are divided into a small ranges of 2<n>=2<3>=8 and rough A/D conversion is applied to the signal depending on its level by a low resolution A/D converter 22 and the result is outputted to a window selector 23. The selector 23 divides output data into small ranges (R0-R7), which are converted into an analog signal by a D/A converter 24. The analog signal is used for offset voltages (0V, Vc1-Vc7) and a difference DELTAA between an output Vi of a sample-and-hold circuit 27 sampling and holding the input signal IN and each of the analog offset voltages is obtained by a subtractor 25 and an accurate A/D converter 21 is used to apply A/D conversion to the difference. Its output data DELTAD are added to a range designation signal from the selector 23 at a data synthesizer 26 to obtain a digital output signal OUT. Thus, the A/D converter with high resolution is obtained.

Title: Vertical type reduced pressure vapor phase growth device
Inventor: HARASHIMA KEIICHI
IPC: H01L21/31
Filed: 1991-05-21
Abstract: PURPOSE:To improve the uniformity of the thickness and the quality of a film formed on a wafer by changing the flow direction of raw gas during a film forming process on the way. CONSTITUTION:Valves 9A and 11B are opened and valves 9B and 11A are closed directly after the start of film formation. Thus, raw gas flows through the second gas introducing pipe 12B at the bottom of an inner pipe from the bottom to the top of a boat 5. Then, at the point of that the accumulation of the half of the target film thickness is attained, the valves 9A and 11B are closed and the valves 9B and 11A are opened. The raw gas flows through the first gas introducing pipe 12A at the bottom of an outer tube and the flowing path is changed from the top to the bottom of the boat 5. As a result, the film growing speed on a wafer 4 positioned at the bottom of the boat 5 is high for the first half period of the film formation, and for the last half period of the film formation, the film growing speed of the wafer 4 positioned on the top of the boat 5 is high. Therefore, even when the gradient of temperature distribution in a reacting pipe is smaller compared with the conventional orientation, the thickness of the film on the wafer in a batch is made uniform.

Inventor: WATANABE HIDEYASU
IPC: G05D3/12
Filed: 1990-05-01
Abstract: PURPOSE:To hold a magazine rack at a stopping position purely electrically and to easily perform stoppage holding by permitting a weak holding current in an ascending driving direction to flow on a motor in a state where the positioning of the magazine rack is stopped. CONSTITUTION:A stoppage holding circuit 22 which permits the weak holding current in the ascending driving direction to flow on the motor 14 in the state where the positioning of the magazine rack 12 is stopped is provided at the driving circuit 20 of the motor 14. The stoppage holding circuit 22 permits the holding current less than a fraction of the ordinary elevation driving current to flow on the motor 14 when the positioning of the magazine rack is stopped. Thereby, the sopping position can be held by overcoming torque in a reverse direction due to the dead weight of the magazine rack by the torque by the holding current.
