Title: Production of sulfide having chevrel phase
Inventor: TANAKA TAKAO
IPC: C01G1/12
Filed: 1989-09-21
Abstract: PURPOSE:To safely obtain a sulfide having a chevrel phase and useful as a superconducting material, an electrode material for a secondary battery, etc., in a high yield by mixing a specified metal (sulfide) with metallic molybdenum and sulfurizing the mixture by heating in a flow of a sulfurizing gas. CONSTITUTION:At least one kind of metal selected among Li, Na, Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Pd, Ag, Cd, In, Sn, Ba, Ln, Pb, Ce, Nd, Sm, Gd, Dy, Yb and Lu or the sulfide of the metal is mixed with metallic molybdenum and this mixture is sulfurized by heating in a flow of a sulfurizing gas to obtain a sulfide having a chevrel phase. Gaseous hydrogen sulfide diluted with gaseous nitrogen is suitable for use as the sulfurizing gas. Since unlike the conventional method this method does not require a sealed quartz tube and dangerous ethyl ether, the sulfide is safely produced in large quantities.

Title: Air cleaning device
Inventor: MURAOKA ATSUSHI
IPC: B03C3/74
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To efficiently and simply clean an ionizing line by providing a control part which once returns a cleaning member to a home position to perform an automatic cleaning operation again, when an abnormality occurs during driving an automatic cleaning device for the ionizing line. SOLUTION: When a large foreign substance sticks to an ionizing line 48 and a cleaning member 67 cannot ride over the foreign substance during the movement of a slider 66 in a cleaning operation, the cleaning member 67 sometimes stops halfway through its passage. In this case that the foreign substance occurs, a threaded shaft is reversed to once return the cleaning member 67 to a home position(HP). Next, an automatic cleaning operation is resumed and then it is interpreted whether an abnormality is again generated. When the abnormality does not occur, the cleaning operation for the ionizing line 48 is continued to complete it without the return procedure. When the abnormality occurs, it is interpreted how many times such an abnormality has occurred upto its present detection. Then when the total frequency of the abnormality is not yet upto a set frequency level, the cleaning member 67 is returned to the home position by reversing the threaded shaft and the automatic cleaning operation is again performed.

Filed: 1985-10-29
Abstract: PURPOSE:To shorten a time required for focusing by discriminating the existence of detecting reliability for objective lens focus detecting state based on a high- order space frequency component and switching a focus detecting area to adjust the focus of a photographing lens. CONSTITUTION:Optical images respectively obtained from two divided exit pupils of a photographing lens 29 are detected by a pair of photoelectric conversion arrays arranged in a photoelectric conversion circuit 30.

Title: Chip mounted substrate checker
Inventor: HIRAISHI SATORU
IPC: G06T7/00
Filed: 1987-09-30
Abstract: PURPOSE:To decrease the number of times of erroneous detection by designating the terminal part of chip parts and the pad part of a printed circuit board as a check objective area with a compound mask pattern, comparing and collating obtained picture data with an error pattern decided beforehand, and recognizing a defect. CONSTITUTION:A figure shows a condition in which chip parts 3 are mounted at a pad part 5 on the printed circuit board, and the oblique line part of the figure is a check objective area 1. These oblique line parts are set by a program with the use of the compound mask pattern. In the figure, when the chip parts exceed a misregistration tolerance limit 2, they are regarded as the defects by the compound mask pattern. At the time of the lack of an article, since the picture data of a terminal part 4 of the chip parts image-picked-up by a television camera are omitted, they are recognized as the defects by the compound mask pattern in the same way. Thus, by limiting the check objective area 1 to the terminal part 4 of the chip parts 3 and to the pad part 5 of the printed circuit board, the number of times of erroneous detection can be decreased.

Abstract: PURPOSE:To obtain a magnetic recording medium having improved dispersibility of magnetic powder in a coating type magnetic layer by incorporating a sulfosuccinic acid compd. of the specific weight by the weight of a specific polyoxyalkylene glycol compd. in the magnetic layer. CONSTITUTION:A magnetic recording medium contains a substd. or non-substd. polyoxyalkylene glycol compd. and the compd. expressed by the formula I at 0.1-100wt% by the weight of said compd. The polyoxyalkylene glycol compd. and the compd. expressed by the formula I are incorporated in the magnetic layer in the above-mentioned way. The packability and orientability of the magnetic powder are thus improved by the excellent dispersion effect of the sulfosuccinic acid compd. expressed by the formula I in the magnetic layer. The function to provide an excellent magnetic characteristic or electromagnetic conversion to the magnetic medium is best utilized; moreover, the decrease in the binding force between the magnetic powder and the binder, the adverse influence on the heat resistant preservability occurring in oozing of the compd. on the magnetic layer surface and the consequent adhesion between the layers and the decreased wear resistant occurring in dislodging of the magnetic powder are obviated. Tape squeaking is decreased and the dispersibility of the magnetic powder is improved.

Abstract: PURPOSE:To easily obtain a two-terminal element type large-screen high- definition liquid crystal display device which has high picture quality by dividing the shape of a sintered body varistor element and installing the element mounting on adjacent picture element electrodes. CONSTITUTION:The shape of the sintered varistor element 13 is divided and the sintered body varistor element 13 is installed between a row electrode 11 and a picture element electrode 12 while straddling two adjacent picture element electrodes.
