Title: Film quality controlling device and method
Inventor: WATABE MASAYUKI
IPC: H01L21/3205
Filed: 1992-04-20
Abstract: PURPOSE:To completely detect the deterioration in the film quality due to an abnormal atmosphere when a film is deposited on a substrate by a method wherein the partial potential of atmospheric components is measured to be held in previously set up timing and then compared with the measured value of the later partial potential to measure the difference therefrom for making a comparison with an upper limit difference value. CONSTITUTION:N2 partial potential output of the guadrupole mass analyzer 1 is held by a holding circuit 2 before producing plasma to be assumed as an initial value. Next, the plasma is produced to start the film deposition for measuring the difference between the N2 partial potential output of the quadrupole mass analyzer 1 and the previously held initial value by a difference circuit 3. At this time, the partial potential upper limit value adversely affecting the previously investigated film quality is set up in the upper limit setting up circuit 4. Next, the difference measured by the difference circuit 3 is compared with the N2 partial potential upper limit value by a comparison circuit 5 and if the difference exceeds the N2 partial potential upper limit value, an alarm exciting circuit 6 is initiated for exciting an alarm. Through these procedures, the deterioration in the film quality due to an abnormal atmosphere can be perfectly detected.

IPC: F02D45/00
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To accomplish quick start, while exhaust emission control performance is secured by providing a start control means for continuing cranking in a state of stopping fuel injection to an engine during a designated period after the cranking start of the engine, and then starting fuel injection to start the engine. SOLUTION: When a start switch 13 is turned on, a starter 12 is started by a control unit 14 to start cranking, but fuel injection and ignition are put in a stop state. Secondly, it is determined whether designated time is elapsed, and after the lapse of a prescribed time, it is determined whether the stroke of a cylinder is discriminated, according to the detection of a cylinder discriminating signal. When the stroke discrimination is performed, fuel injection from a fuel injection valve 8 is started from the first cylinder where performing fuel injection sequentially at the preset fuel injection time, and simultaneously ignition operation is started.  Thus, after the start of cranking, the intake air is adiabatically compressed to raise the temperature in a combustion chamber, and flow velocity of intake air is increased to improve starting performance after the start of fuel injection.

Title: Method for analyzing silica surface
Inventor: ARAMATA MIKIO
IPC: G01N24/08
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To specify the type of silane or siloxane, by mixing a surface treatment silica with siloxane that differs from a surface treatment seed, repeatedly integrating the measurement of SiDD/MASNMR and SiCP/MASNMR with a short period for a plurality of times, and performing spectrum analysis. SOLUTION: A proper amount of siloxane (a single substance such as (Me2 SiO)4 of a liquid that differs from a surface treatment seed) is added to silica before mixing, and SiDD/MASONMR is measured, thus judging the stiffness of Si in silica. In this case, a wait time may be equal to or less than 90 seconds. After repeating this sort of measurement for several tens of times, the spectrum intensity ratio of siloxane being added to silica is measured, and the surface activity of silica is estimated in comparison with a calibration curve. When the organization or the like of a surface-treating agent that exists on the surface of the surface treatment silica or near it is to be directly analyzed, measurement is made by the combination of SiDD/MASONMR and SiCP/ MASONMR.

Title: Radar equipment
Inventor: SEO TAKASHI
IPC: G01S13/44
Filed: 1983-06-03
Abstract: PURPOSE:To prevent tracking from being defective or disabled owing to a radio wave disturbance by radiating a transmit signal from a monopulse antenna after amplitude modulation similar to that in conical scanning. CONSTITUTION:The amplitude modulation similar to that in conical scanning is imposed to the output of a coherent oscillator 1 by an amplitude modulating circuit 25 which is driven by a modulating signal generating cirlcuit 16 before the pulse modulation of a pulse modulator 3. Consequently, the transmit pulses outputted by the monopulse pulses 8 appeared to be scanned conically. Therefore, it seems that tracking is carried out by a conical scanning type tracking radar to select a wrong disturbing radio wave on a tracking target side, and a defect of tracking, and a failure in tracking are prevented to continue the tracking by a monpulse radar.
