Title: Production of (meth)acrylic acid ester
Inventor: KUROKAWA MASAHIRO
IPC: C07C69/54
Filed: 1988-04-06
Abstract: PURPOSE:To easily obtain the subject compound in high purity and yield, by reacting methyl (meth)acrylate, etc., with an alcohol using a tetraalkyl titanate as a catalyst and a hindered phenol as a polymerization inhibitor. CONSTITUTION:The objective compound useful as a resin, coating, adhesive or industrial raw material can be produced by reacting 1.0-4.0mol of methyl or ethyl (meth)acrylate with 1mol of a 3-20C alcohol such as ally alcohol in the presence of 0.001-0.1mol (based on 1mol of said alcohol) of a tetraalkyl titanate catalyst such as tetraisopropyl titanate and 100-10,000ppm (based on said acrylate) of a hindered phenolic polymerization inhibitor such as 3,5-di-t- butyl-4-hydroxytoluene at 80-150 deg.C, preferably at the refluxing temperature and distilling the reaction product to collect a high-boiling fraction as the objective compound.

Title: Analysis method using x-ray diffraction
Inventor: SHINDO TAKUYA
IPC: G01N23/20
Filed: 1990-03-29
Abstract: PURPOSE:To analyze material by computing specified two kinds of indexes L1 and L2 based on the actually measured X-ray diffraction data of an unknown sample and the standard data of the X-ray diffractions of various kinds of materials, and retrieving the material having the large index value. CONSTITUTION:Specified indexes L1 and L2 are computed by using a diffraction-line number No in standard data, a diffraction-line number no that agrees with the actually measured diffraction lines of an unknown sample, an actually measured diffraction-line number N of the unknown sample and a line number (n) that agrees with the diffraction lines of the standard data. When the unknown sample is the single material, L1=L2=1o. Since there is a case wherein the diffraction lines of other materials are overlapped, however, the single component cannot be judged even if both L1 and L2 are closed to 1. However, when L1 is small and L2 is large, mixing of other component is found. When only L1 is specified as the index, the secondary component might be missed. Balance is obtained between the fact that L2 is the square of no/N and the fact that L1 is the product of two terms. L1 and L2 are made to have about equal value. Thus, the difference in numerical values in the case of agreement/ disagreement is expanded. The judging accuracy of the sample component is improved by using two kinds of indexes.

Title: Apparatus for inspecting inner surface of pipe
IPC: G01N21/954
Filed: 1992-04-06
Abstract: PURPOSE:To perform inspection highly accurately in a short time by efficiently capturing moving laser beam. CONSTITUTION:The scattered light of laser beam which is emitted from a rotating laser-pattern generating part 1 on the inner surface of a pipe, is captured by visual sensors 2a-2n. Inspection is performed by using a signal processing device 14. The field of view under inspection is divided into several parts. One of the visual sensors 2a-2n is made to correspond to respective divided parts. The rotating position is detected with a rotation sensor 9. The visual sensors 2a-2n, which are located at the applicable pieces, are selected and switched all the time with the signals from a visual-sensor synchronizing circuit 10 based on the rotating-position signals. The captured inspection image signals are sequentially inputted into the signal processing device 14 without missing and further inputted into an output device 15.

Title: Signaling converter
Inventor: TAKEKOSHI YOSHIO
IPC: H04M7/00
Filed: 1985-04-19
Abstract: PURPOSE:To obtain a signaling converter which is adaptive to an analog exchange with a manual holding function by providing a current detector which detects the backward current of a loop circuit. CONSTITUTION:When an actuation signal is sent from a calling subscriber side, a contact 5 is made to flow a backward loop current, so the current detector 6 sends out a 0 level to a microprocessor MPU and when the side of the analog exchange 1 answers, the current flows reversely, so the current is not detected and a 1 level is sent out. Further, the current is inverted again in direction on normal on-hook operation, so the current is detected and the 0 level is sent to the MPU. When on-hook operation is performed in manual holding mode, no loop current flows, so the current detector 6 still sends the 1 level to the MPU as well as during a talk and then the MPU checks signals from a blocking detector 4 and current detectors 3 and 6 to discriminate normal on-hook operation and on-hook operation in manual holding mode.

Abstract: PURPOSE:To realize low prime cost by forming a bottom-fitted center lead insertion hole, which is equal in its diameter to a center lead and has a prescribed depth, in the center of a circular board-shaped part which is fitted to a filament end part on a lower side of an upper end shield, and next by inserting a center lead end part into this hole so as to be junctioned with the upper end shield. CONSTITUTION:A bottom-fitted center lead insertion hole, which is equal in its diameter to a center lead 4 and has a prescribed depth, is formed in the center of a circular board-shaped part which is fitted to a filament end part on a lower side of an upper end shield 2, and a center lead 4 end part is inserted into this hole so that it is junctioned with the upper end shield 2 by welding or brazing or the like. Namely, since the center lead insertion hole of the upper end shield 2 is provided with a bottom, the center lead 4 enters the upper end shield 2 by a constant length even if the center lead 4 is inserted into this hole, and own weight of the upper end shield 2 is supported by the center lead. The center lead 4 does not enter the upper end shield 2 in excess of the prescribed length accordingly, and also the upper end shield 2 does not enter the filament end part in excess of the prescribed length. A high-melting-point and expensive material can be hence prevented from being wasted.
