Title: Method for estimating ash content of coke by fluorescent x-ray spectroscopy
Inventor: MIYAWAKI MOTOKAZU
IPC: G01N33/22
Filed: 1994-09-26
Abstract: PURPOSE: To enable estimating the ash content of coke with high accuracy by mixing a binding agent in the coke crushed, pressure molding the coke into a briquette shape, then calculating the content of each of specific four elements from a preset calibration curve and in accordance with the X-ray intensities of the specific four elements which are measured with a fluorescent X-ray emission spectrometer, and using a specific equation. CONSTITUTION: Coke is crushed with the addition of a binding agent and is pressure molded into a briquette-shaped sample. The X-ray intensities of Si, Al, Ca and Fe in the molding are measured with an X-ray fluorescent emission spectrometer. In accordance with the intensities, the contents of SiO2 , Al2 O3 , Cab, and Fe2 O3 are calculated from a preset calibration curve on which, when the elements are zero, the fluorescent X-ray intensities are zero. The ash content AΔh of the coke is calculated on the basis of the equation (A1 =1.039, B1 =1.240, C1 =1.865, D1 =1.188, K1 =0.311). Thus the time required to measure the ash content can be reduced and the labor required of analysis persons reduced.

Title: High-sensitive light wave reflection measuring device and light-wave echo tomographic device using same
Inventor: TANNO NAOHIRO
IPC: G01N21/17
Filed: 1994-09-14
Abstract: PURPOSE: To enable detecting at high sensitivity and high S/N the distribution of the positions of boundary planes within an object to be measured which differ in refractive index by detecting an output position which is produced corresponding to a reflecting position by the combination of a multi-mode laser beam reflected from within the object to be measured and a reference beam which is varied in delay time. CONSTITUTION: A laser beam from a multi-mode laser oscillator 1 is split into two beams by a beam splitter 3, one of the beams reflected by a scanning reflector 6a and Doppler-shifted in frequency to become a reference beam having a delay in position that corresponds to the distance over which the reflector 6a moves; the other beam propagates through an object 4 to be measured which is made of multiple layers of materials with different refractive indexes, and reflections occur at each of the boundaries among the layers so that the phase of the reflected light wave in each of the multiple of modes is delayed in accordance with the boundary positions, and that the beam is combined 3 with the reference beam.  In-depth reflecting positions with different refractive indexes can be detected through the detection 7 of the combined beams and the processing of a pulse beam that is produced at a delayed time corresponding to a reflection point produced by the coherent components of the combined components.

Abstract: PURPOSE:To prevent output compliance caused by the fluctuation of an output voltage to evaluate and select a D/A converter with high accuracy, by evaluating the D/A converter to be evaluated by adjusting the sum of the outputs of the D/A converter to be evaluated and another D/A converter which is used as a reference to become constant.

Abstract: PURPOSE:To reduce lateral diffusion of a drain region and a source region and to decrease parasitic electrostatic capacitances between a substrate and the drain region and the source region, by providing an MOS type semiconductor element, in which insulating regions are provided between the facing side surfaces of the drain region and the source region. CONSTITUTION:In an MOS type semiconductor element, insulator regions 4 are provided between the facing side surfaces of a drain region 2 and a source region 3 on a semiconductor substrate 1. It is desirable that said insulator regions 4 are provided between the facing side surfaces between the source region 4 and the drain region 2 other than a region 6, which is to become a channel. It is advantageous to form said insulator regions 4 with silicon oxide or silicon nitride in a semiconductor device using a silicon substrate. Thus, the depth of the junction of the drain region 2 ad the source region 3 is not affected by the channel length owing to the presence of the insulator regions 4. The channel region 6 is formed after the drain region 2 and the source region 3 are approximately completed. Therefore the effect of the lateral expansion of the source region 3 and the drain region 2 on the channel length is made small to the extent of the depth of the channel region.

Abstract: PURPOSE:To reduce bad effects of irradiated laser beam to the periphery and energy loss by converging the laser beam in an elliptical shape through a lens to irradiate a material to be worked with the laser beam and agreeing the long axis of this ellipse to the extension direction of a working part. CONSTITUTION:The case 25 of an emitting unit 8 where the laser beam is converged and emitted is made up by connecting an upper case body 11 and a lower case body 21 with an extension ring 23. A plano-convex lens 17 is set to the upper case body 11. On the other hand, a plano-convex 1st lower lens 28 and the 2nd lower lens 31 of a semi-circular cylindrical lens are attached vertically to the lower case body 21. By passing the laser beam from a laser oscillator (not shown) to this emitting unit 8 through an optical fiber 7, these laser beam is converged so that an optical mottle of the laser beam on a plane vertical to an optical axis H is elliptic. The material to be worked where the long axis of the ellipse and the extension part of the working part are agreed is irradiated with the converted laser beam and machined by the converged laser beam. Thus, the periphery of the working part irrelevant to working is prevented from being irradiated with the laser beam as possible.

Title: Flat thermal fuse
Inventor: KAKIZAKI TOSHIKI
IPC: H01H37/76
Filed: 1993-09-21
Abstract: PURPOSE:To easily prevent the peeling of a plastic film by the fusion expansion of a flux at general use by providing a flux layer having a prescribed application width between plastic films in contact with a low melting point fusible metal wire. CONSTITUTION:A flux 3 is applied in contact with a low melting point fusible metal wire 2 in a width (b) 10-20 times the width (a) of the wire 2. Upper and lower plastic films 11, 12 are adhered on a contact critical surface 4 by an adhesive or by means of fusion. Thus, even when the flux 3 is fused and expanded by the ambient heat of a combustion chamber at general use, the space between the upper and lower films 11, 12 in the part of the flux applying width is expanded. Since the expanded portion of the flux 3 is absorbed by the volume increase between the films 11, 12 by the expansion, the generation of an internal pressure is sufficiently suppressed. Thus, the peeling between the films 11, 12 and the outflow of the expanded flux 3 can be prevented.
