Title: Apparatus and method for depositing thin film
Inventor: SEKINE MAKOTO
IPC: H01L21/76
Filed: 1987-03-18
Abstract: PURPOSE:To make it possible to perform ideal, perfect embedding selectively in a groove, by generating plasma in a reaction container, which contains a substrate to be treated, growing depositing seeds in the container, setting the temperature of the substrate at the boiling point of the depositing seeds or less, and forming a thin film layer, which performs stable adsorption, on the surface of the substrate. CONSTITUTION:As reacting gas, O2 and tetramethylsilance Si(CH3)4(TMS) are introduced into a reacting container 1. Then a silicon oxide film is formed on the surface of an Si substrate of a substrate 6 to be treated. At this time, oxygen radicals and hexamethyldisiloxane (Si(CH3)2)2O trimethylsilanol Si(CH3)3OH, which are the reactant of the TMS, are liquified. A liquid layer is formed on the surface of the substrate. SiO2 particles, whose reaction is further progressed in a vapor phase, are inputted in the liquid layer. Oxidation advances, with the oxygen radicals being intruded and with oxygen ions being implanted. Meanwhile, since the liquid layer is well conformable with the surface of the substrate, the liquid layer can present most stably even at the corner part of the bottom of a trench groove, where a broad contact area can be obtained with the surface of the substrate. Since the film is formed in this deposition in a pile-up mode from the bottom of the trench groove, embedding in the groove having a high aspect ratio and super flattening can be performed.

Filed: 1992-03-18
Abstract: PURPOSE:To eliminate the noise of input picture and to accurately trace the only reflection board by adding a program eliminating the input picture exceeding an allowable value as noise and comparing the input picture from an one- dimensional camera with the allowable value. CONSTITUTION:A trailer 10 loading a load coil 12 is irradiated with a light from a projector 13 of a camera truck 16 at the top, and the light reflected by a reflector board 11 is received by a camera 14. A camera controller 15 synthesizes signals of two cameras 14 to one signal, which is sent as a synthesized video signal to a picture processor 17 for picture processing. In this case, the only presence or absence of the reflector board 11 has been discriminated, so that the oil spread around the reflector board has been apt to be recognized as the reflector board. To solve this problem, the allowable value is set to the position where the reflector board 11 is likely to be located, and the processing regarding the only ones within the range as the reflector board 11 is provided to reject others as noise. Thus oil or the like is eliminated as noise, resulting in outputting the normal recognition result.

Title: Method and circuit for measuring opening time difference of breaker
Inventor: SENDA YUTAKA
IPC: G01R31/333
Filed: 1980-05-13
Abstract: PURPOSE:To measure a difference in opening time efficiently by coupling an AC power source electromagnetically with the closed circuit consisting of a main contactor, making resistor and auxiliary contactor. CONSTITUTION:With the series circuit of a resistor 2A and contactor 3A of the closed circuit 4A including a main contactor 1A, making resistor 2A and the auxiliary contactor 3A, two current transformers 11A and 12A are coupled electromagnetically. One transformer 11A has an AC power source 13A, and the other transformer 12A a current detector 15A. In breaking operation, the auxiliary contactor 3A opens first to cease the current of the detector 15A. Next, when the main contactor 1A opens, the current of the detector 7A disappears. An opening time difference is therefore measured by the difference in detection time between two detectors. Thus, the measurement is taken with the assembly completed, so that the measuring operation will be performed efficiently.
