Title: Formation of terminal electrode for solder bump mounting
Inventor: SATO NOBUO
IPC: H01L21/60
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent solder from flowing into an interface between a wiring electrode pad and an insulating protective film and to reduce the number of fabricating steps to achieve low fabricating costs, by forming the insulating protective film and then making the insulating film act as a plating resist to form a bump adhesive layer. SOLUTION: A wiring electrode pad 2 is formed on an insulating substrate 1, and then subjected to an oxidation process to from an oxidized layer 8.

Title: Burster
Inventor: NAKAMURA SHINYA
IPC: B26F3/02
Filed: 1989-09-01
Abstract: PURPOSE:To bring a cutting off edge surely into contact with sewing machine stitches and cut off a continuous paper sheet easily and with small force, by providing a pair of paper sheet pressors which are retained so as to advance/retreat freely in a cutting off edge cutting-in direction at confronting positions with the cutting off edge of a plate shape placed between them and whose inclined surfaces that go into a recessed portion are formed on a cutting off edge surface side. CONSTITUTION:Transport rollers 4, 5 are stopped, and they together with paper sheet pressors 13, 14 give tensile force to a continuous paper sheet 1 while the slip of the paper sheet 1 is being allowed by means of paper sheet pressors 13, 14. At this time, the paper sheet 1 is bent into dogleg form at a sewing machine stitches part 1a. On this occasion, in the case of sewing machine stitches 1a being shifted to the upper stream side than a cutting off edge 11, there occurs more slip between the paper sheet 1 and the upper stream side transport rollers 4. As a result, under a condition in which the paper sheet 1 is press-welded to the recessed portion 8 of a guide plate 2 by means of paper sheet pressors 13, 14, sewing machine stitches 1a can be positioned at the center of the recessed portion 8. As a result, the paper sheet 1 can be easily cut off by bringing the cutting off edge 12 into contact sewing machine stitches 1a.

Title: Method of controlling cereal drier
Inventor: KANEKO AIJIRO
IPC: F26B23/02
Filed: 1987-09-10
Abstract: PURPOSE: To secure stable combustion while enabling the optimum drying temperature to be maintained in a grain dyer with a combustion device by controlling a combustion quantity based on a set degree of drying and the detected temperature of hot air during the drying to intermittently operate a combustion at the combustion quantity below the minimum combustion quantity. CONSTITUTION: Drying temperature is set by a setting part 1 and inputted into a comparison arithmetic section 5 together with the temperatures detected by an outside air temperature detecting section 2 and a hot air temperature detecting section 3. The comparison arithmetic section 5 takes in moisture information of grain from a moisture detecting section 4 to perform a comparison computation of the information based on the specified procedure and outputs the results to a combustion quantity increase/decrease control section 6, which 6 in turn, increases or decreases the combustion quantity to attain a preset temperature. If the set temperature is not gained even under the minimum combustion quantity, an intermittent combustion control part 7 is actuated to keep the temperature at a preset value by intermittent control of the combustion.  This can stabilize the combustion while allowing maintaining of the optimum drying temperature.

IPC: G11B20/10
Filed: 1986-09-26
Abstract: PURPOSE:To attain matrix arithmetic processing with simple constitution by applying data inverting processing among matrix arithmetic processings at a digital data area and applying data addition processing at an analog data area. CONSTITUTION:Digital data is fed as it is to a fixed contact point 23a of a switch circuit 23 and a signal of inverted digital data is fed to the other fixed contact point 23b of the switch circuit 23. When a switching signal L/R is at an L level, the switch circuit 23 is changed over to the position of the fixed contact point 23a, and when the switching signal L/R is at an H level, the switch circuit 23 is changed over to the position of the fixed contact 23b, then the digital data and its inverted data are obtained alternately at an output terminal 31. Thus, the output signal at the output terminal 31 is separated into the digital data and its inverted data to apply D/A conversion and both of obtained analog data are added through resistors to attain the arithmetic of (L-R).

Title: Electrophotographic developing agent
Inventor: AKAMATSU AKIRA
IPC: G03G9/097
Filed: 1988-09-09
Abstract: PURPOSE:To obtain an electrophotographic developing agent capable of stably providing charge characteristic against variation of temp. and humidity, etc., of external atmosphere by adding a single or plural kinds of hygroscopic material and kneading with other toner components, and mixing a single or plural kinds of efflorescent material as third component to the previously prepd. above-described mixture. CONSTITUTION:A single or plural kinds of hygroscopic material is(are) admixed with a toner, and a single or plural kinds of efflorescent material is(are) mixed with the mixture. Although the efflorescent material evaporates more quickly the lower the humidity is, the evaporated water is absorbed by the hygroscopic material if the hygroscopic material is contained together with the efflorescent material. Accordingly, a moisture content of a developing agent is held at a fixed value independently of the variation of temp. and humidity, etc., of atmospheric air, and the dependency of the amt. of charge on environmental condition is excluded and the stability of a picture quality is retained. At the same time, the charge is restored immediately to a state of an almost constant saturation charge even if an excess charge is generated because of a dissipation velocity of the charge increases. Thus, an electrophotographic developing agent capable of providing stable charge characteristic against the variation of humidity, temp., etc., of atmospheric air is obtd.

Title: Detoxifying treatment of organic chlorine compound by mixed fused salt
Inventor: ASAKURA SHUKUJI
IPC: A62D3/30
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To safely decompose org. chlorine compds. into harmless inorg. salts and water without discharging harmful substances or waste gas by bringing the org. chlorine compds. into contact with a mixture fused salt essentially consisting of alkali metal hydroxide and with water vapor in an inert atmosphere to react. SOLUTION: In this treatment, chlorofluorocarbons, chlorobenzenes or org. chlorine compds. containing sulfur are directly reacted with a mixture fused salt and decomposed in a sealed chamber 1. Since the compds. are directly reacted with the mixture fused salt, strong acid such as hydrogen fluoride and hydrogen chloride is not produced in the decomposition process, and more over, no other harmful decomposition product is produced. The chlorofluorocarbons introduced into the mixture fused salt are wholly reacted with the mixture fused salt and decomposed into harmless inorg. salts and water. Since the decomposition is performed in an inert atmosphere or reducing atmosphere, complete treatment without discharged gas and generation of dioxins or the like is possible.
