IPC: G01B11/06
Filed: 1990-07-09
Abstract: PURPOSE:To efficiently extract film thickness information from a reflection interference spectrum with a comparatively narrow wave number region by providing a data replenishing process. CONSTITUTION:First a film interference spectrum is measured by a common method, and if a low frequency component in the obtained spectrum is removed, a film interference spectrum as shown in the figure can be obtained. This spectrum is subjected to waveform data processing and addition of spectrum data. That is, reflection interference spectrum intensity data on the left end of the interference spectrum figure is added as interference spectrum intensity data from 0 to sigma1cm<-1> while spectrum intensity data on the right end is added as reflection interference spectrum intensity data from a wave number sigma2 to sigmamaxcm<-1>. Then the reflection interference spectrum data after waveform data processing is subjected to Fourier-transform, a spatial-gram as shown in the figure can be obtained. Peaks of the spatial-gram is searched and film thickness is calculated from distance intervals between the peaks.

IPC: H04N1/40
Filed: 1984-08-31
Abstract: PURPOSE:To prevent overflow of a reception buffer memory with simple constitution by providing a transmission control means guaranteeing a minimum coding main scanning line transmission time to the transmission side. CONSTITUTION:A memory address circuit 44 outputs a transmission buffer memory overflow generating alarm signal (k) to a device control section 30 when an non-use area of a memory reaches a prescribed value or over, and the section 30 outputs a scanning stop signal (q) to a picture reader 21. Since the picture reader 21 uses the scanning stop signal (q) to interrupt scanning of a picture, no picture signal (r) is outputted to a band compression section 22 and the compression code input to a transmission buffer memory 23 is intermitted. Since the compression code in the transmission buffer memory 23 is decreased at each transmission frame, the non-use area of the memory 42 is increased, and when the value reaches a prescribed amount or over, the alarm signal (k) is released and the scanning stop signal is released, then the picture reader 21 restarts the scanning.

Abstract: PURPOSE:To cast a pipe body having a uniform pipe thickness by blowing a gas to the flow of molten metal and controlling the flow rate of the molten metal in a charging route from a charging ladle to the inside surface of metallic flasks. CONSTITUTION:Gas blow nozzles 5a, 5b are disposed in proximity to the charging ports 3a, 3b of a ladle 3 diagonally above said parts, and the nozzles 5a, 5b are communicated with a gas force feeding source via solenoid valves 16 and a reducing valve 17.

Title: Member for fusion zone of burned ash portion of waste
Inventor: NANBA MASAO
IPC: C04B5/00
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To improve corrosion resistance to ash molten slag, by forming the member for a fusion zone out of a spinel type compound which is represented by a specific formula in the member for the fusion zone of the burned ash portion of waste. SOLUTION: In the member for a fusion zone of the burned ash portion of waste which constitutes the surface in a furnace that forms molten slag by heating the ash portion that is generated by burning the combustion matter originated from waste, this member for the fusion zone is formed of a spinel type compound that is represented by a formula I. In this formula I, it is expressed as: 0<=α<=1, 0.714<=β<=$1, 0<=γ, 0<=δ, 0<=γ+δ<0.5. According to this member for the fusion zone, when the ash portion is heated (about 1300 deg.C) to form the molten slag, the member which contacts with this is formed out of Cr-containing spinel type compound. Thereby, Cr2 O3 , enlarges its surface tension with the molten slag, and the infiltration of slag is suppressed.  Moreover, the mass transfer rate in the slag boundary layer which contacts to a refractory material is decreased.
