Title: Via hole inspecting device
Inventor: OKADA HIDEO
IPC: G01B11/24
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To form a satisfactory via hole and improve the yield and reliability by judging the quality of a via hole on the basis of the image information generated by binarizing an image signal according to the brightness of the observed reflected light. SOLUTION: A binarizing circuit 21 sets a prescribed threshold on the basis of the analog image signal (a) from a CCD camera 13, and generates a binarized image signal (b) binarized according to the detected brightness. Namely, a threshold th1 is set and binarized in order to discriminate a bright range showing the metal layer area covered with an insulating layer from a dark range showing the metal layer area exposed into a via hole. The binarized image signal (b) is stored by a memory circuit 22 and arranged as the image information C to be processed.  An exclusive logic circuit 31 performs the exclusive OR processing of the binarized image information C from a binarizing means 2 and the design data related to the form of the metal layer formed on the lower layer of the interlayer insulating layer to extract only the image component corresponding to the metal layer exposed into the via hole.

Title: Silencer
Inventor: NAKAMURA TADAO
IPC: F01N1/06
Filed: 1981-05-21
Abstract: PURPOSE:To deviate the phase of a sound wave generated from the outlet side of a main tubular body and improve the silencing effect with a simple construction by providing a multiplexed and spiral partition plate in a space between the inner cylinder and outer cylinder to divide the flowpath outside the inner cylinder. CONSTITUTION:An inner cylinder 4 is inserted into the inner side of an outer cylinder 3 both ends of which are connected to each of pipelines 1 and 2 at the inlet side and outlet side. A partition plate 5 partitioning the space in a double and spiral manner is provided in a space between the above both cylinders 3 and 4, and the flowpath between the cylinders 3 and 4 is divided into two spiral flowpaths 6 and 7. Further, one spiral flowpath 7 is partitioned in the midway by a partition plate 8. Accordingly, the sound wave propagated through the pipeline 1 is divided into a sound wave propagated through the flowpath 9 within the inner cylinder and a sound wave propagated through the spiral flowpath 6. Since the lengths of both flowpaths 6 and 9 differ from each other, the phases are generally different from each other at the outlet amalgamated point. Accordingly sound waves of the frequency component determined by the difference between the lengths of both flowpaths 6 and 9 are cancelled by the mutual interference and propagation to the pipeline 2 is prevented.

Title: Nuclear fuel rod
Inventor: OKUDA TAKESHI
IPC: G21C3/02
Filed: 1988-03-30
Abstract: PURPOSE:To prevent misloading even when there are various kinds of enrichment by changing combinations of the width, length, and height of a rib for misloading prevention according to the enrichment of the nuclear fuel rod. CONSTITUTION:The rib 2 for misloading prevention and a rib 3 for rotation prevention are formed on the outer peripheral surface of the rear end part of the nuclear fuel rod 1 for a high-temperature gas furnace which is sectioned nearly circularly. The height H, width W, and length L of the rib 2 are varied according to the enrichment of nuclear fuel. A groove 6 (not shown in figure) of size corresponding to the rib 2 is formed in the nuclear fuel rod insertion hole of a graphite block 5 (not shown in figure). When a different fuel rod 1 is inserted into the insertion hole 5, the rear end of the fuel rod 1 projects from the graphite block 5 or an abnormal gap is formed between the groove 6 and rib 2, so the misloading is decided visually clearly.

Title: Production of non-oriented silicon steel sheet excellent in iron loss
Inventor: TANAKA OSAMU
IPC: C21D8/12
Filed: 1981-05-23
Abstract: PURPOSE:To obtain a non-oriented silicon steel sheet having an extremely improved iron loss property, by applying a solution of phosphoric acid or a phosphoric radical to a steel slab, containing 4% or less of Si, which has been hot- rolled and then cold-rolled, and then finish-annealing the steel sheet. CONSTITUTION:A steel slab, which has been refined in a melting furnace and controlled such that the steel contains up to 0.010% C, optionally Si, Al, Mn, etc., and especially up to 4% Si, is hot-rolled. The hot-rolled steel slab is cold- rolled by one cycle or by two or more cycles accompanied with intermediate annealing into a sheet having final thickness. After the surface of the cold- rolled steel sheet is clarified by alkali-degreasing or the like, a mixed solution containing phosphoric acid and one or more of phosphates of Al, Mg, Zn, etc. is uniformly applied to the surface. The solution-applied steel sheet is then subjected to finish annealing. In this way, a non-oriented silicon steel sheet excellent in iron loss is obtained.

Title: Heat accumulating material for use in space heating
Inventor: KIHARA YASUNORI
IPC: F24D11/00
Filed: 1982-05-11
Abstract: PURPOSE:To increase the amount of latent heat of solidification and to prevent the overcooling of heat storage material by a method wherein a concentrated solution of sodium acetate trihydrate containing iron (III) dihydrogen tripolyphosphate monohydrate is used as the phase-changeable heat accumulating material for heating which is adopted to store low level heat energy such as the sunlight. CONSTITUTION:The heat accumulating material is produced by adding, as a nucleating agent, 0.2-5.0wt% iron (III) dihydrogen tripolyphosphate monohydrate or magnesium hexaborate heptahydrate to a concentrated solution of sodium acetate trihydrate dissolved in 2.0-12.0wt% water. With the above chemical structure, the tripolyphosphate or hexaborate acts effectively as the nucleating agent and the sodium acetate can retain a large amount of latent heat. For example, with the addition of the tripolyphosphate, the degree of overcooling of the heat accumulating material becomes 1.5-2.3 deg.C and the amount of latent heat of solidification becomes 44-58cal/g. Therefore, it is possible to prevent the overcooling of the heat accumulating material and to increase the amount of latent heat of solidification.

Abstract: PURPOSE:To count the total number of copy sheets correctly by disposing switches at a photosensitive paper insertion hole for manual insertion provided between a separating part and a developing part, detecting the insertion of the photosensitive paper and stepping the counter. CONSTITUTION:An original picture O and photosensitive paper S are contact-exposed by a printing drum 3, and are separated by a separating device 11. The original picture is sent to a paper discharge tray 39 and the photosensitive paper to a developing part 12. At this time, the original picture and the photosensitive paper turn switches S1 and S2 respectively on, by which a counter is stepped. When either  of these switches did not operate, it is judged to be the failure in separation, and the laminated sheets of the original picture and the photosensitive paper are discharged to the outside D of the machine by a passage changing plate 17. If only the photosensitive paper is inserted again into an insertion port 19 after this, the  switches S1, S2 go on, and step the counter; therefore, the number of all the copy sheets passing a developing part 12 is counted.

Abstract: PURPOSE: To produce a carboxylic acid while effectively utilizing a salt and ammonia which are components of a catalyst formed as by-products by hydrolyzing a nitrile or an amide compound. CONSTITUTION: A nitrile or an amide compound is hydrolyzed with an acidic catalyst such as an inorganic acid and an ammonium salt of the acidic catalyst formed as a by-product is electrodialyzed to produce an acid and ammonia. The resultant acid is then used as a catalyst in the step for hydrolyzing the nitrile or amide compound and the produced ammonia is used as a nitrogen source in a step for producing the nitrile or amide compound. When the compound is hydrolyzed with a basic catalyst such as an alkali metallic hydroxide, the salt of the carboxylic acid with the base formed as a by-product is electrodialyzed to produce the carboxylic acid and base. The resultant base is then reutilized as a catalyst in a step for hydrolyzing the nitrile compound.  The ammonia produced by the electrodialysis is reutilized as the nitrogen source in the step for producing the nitrile or amide compound. The electrodialysis can be carried out with an ion exchange membrane constituted of at least one membrane of a bipolar, a cation exchange and an anion exchange membranes.
