Title: Production of mineralized water from pure water
Inventor: MORITA SHINJI
IPC: G01N31/00
Filed: 1986-10-02
Abstract: PURPOSE:To produce mineral water having an optimum content of Ca<2+> by introducing the water injected with gaseous CO2 into a Ca carbonate-packed tower, measuring the Ca<2+> in the water, and controlling the amt. of gaseous CO2 to be injected so that the measured value becomes the desired value. CONSTITUTION:Gaseous CO2 is injected into pure water, and the obtained water contg. gaseous CO2 is sent into a Ca dissolving tower 2 having a packed bed consisting essentially of Ca carbonate granules to sufficiently elute Ca<2+>. After the treatment in the tower 2 is finished, the Ca<2+> in the treated water is measured, for example, by an ion electrode method using a Ca<2+> liq. membrane ion electrode, and the amt. of gaseous CO2 to be injected is controlled so that the measured value becomes the desired value. In this case, when Lm<3>/hr or water contg. bkg/m<3> of CO2 is used for 1m<3> of granules having a m<2> surface area per m<3> packed bed and consisting essentially of CaCO3, the value bL/a is controlled to <=20g/m<2>hr. As a result, mineral water having an optimum content of Ca<2+> can be produced.

Filed: 1990-09-05
Abstract: PURPOSE:To easily detect an open arc phenomenon with high accuracy by constituting the open arc monitoring device by combination of a photoelectric sensor, binary circuits, a monostable circuit, an integration circuit and simple circuit constitution. CONSTITUTION:Arc light is detected by the photoelectric sensor 1. A signal level from the photoelectric sensor 1 is compared with a preset binary level and converted into a signal of ON. OFF by an original signal binary circuit 4. The monostable circuit 5 catches the edge of rising of the output of the binary circuit 4 and outputs a pulse having the preset length. An integrator 6 integrates the output of the monostable circuit 5. An integration output binary circuit 7 compares an output signal level of the integrator 6 with the preset binary level and converts it into the signal of ON. OFF. The open arc monitoring device is thus constituted by combination of the photoelectric sensor, the respective circuits and the simple circuit constitution. Consequently, it can be obviated to bring about large-sized constitution and complication of operation.

Title: Heat exchanger
Inventor: YAMAMOTO YOSHIAKI
IPC: F28D9/00
Filed: 1984-11-09
Abstract: PURPOSE:To restrict dry-out of evaporative fluid and improve the heat transfer performance of the heat exchanger by flowing the evaporative fluid and another fluid into the same direction. CONSTITUTION:The fluid A flows through fin members 2 in parallel to the flow of another fluid B. The fluid A flows into the heat exchanger through a header, formed by a hole 3 located at the upstream side of the other fluid B and a long hole 1, and is branched into respective fin members 2, thereafter, is collected in the header located at the down-stream of the other fluid B and flows out of the heat exchanger. In the fin members 2, drying degree is low at the upstream side and the fluid A evaporates isothermally substantially by receiving heat from the other fluid B while the drying degree becomes higher at the downstream side. On the other hand, the other fluid B provided the fluid A with the heat thereof and the temperature thereof is reduced. Accordingly, a temperature difference between the fluid A and the fluid B becomes small in the downstream side and generation of dry out may be restricted whereby the high heat transfer coefficient may be obtained.

Abstract: PURPOSE: To obtain a sanitary napkin which can rapidly absorb and retain a volume of body fluid, which is soft and feels comfortable, and which can be prevented from being bundled and twisting by making the napkin integrally of separate layers which are selected by density and capacity to hold, disperse and release body fluid. CONSTITUTION: The density of a cover layer 10 of this napkin is very low if the layer 10 includes fabric; the density is preferably about 0.10g/cm<3> or lower. A transferring layer 20 is 100% made of pulp, or made of pulp and rayon at the ratio of about 97:3 to 80:20. The density of the transferring layer is higher than that of the cover layer. An accumulating layer 30 is an high density absorbing layer with pores. This napkin has also a fluid transferring layer 20 directly in contact with and connected to the thick and highly elastic cover layer 10. In addition, there is also the fluid accumulating layer 30 directly in contact with and connected to the transferring layer 20.  Since the accumulating layer 30 is not in contact with the front/rear edges 40 of the cover layer 10 and the front/rear edges 45 of the transferring layer 20, defects in these edge parts can be actually prevented.

Abstract: PURPOSE:To accurately and rapidly control the coating amount of an adhesive, to stabilize the quality of a product and to simplify work by outputting an alarm when it is judged that the coating amount of the adhesive deviates from a control limit value. CONSTITUTION:In an adhesive coating amount control apparatus, the wt. of an adhesive is measured by a wt. meter 1 and the coating amount (t) of the adhesive is calculated on the basis of the winding meter signal (l) of a laminated film from a laminator 8, the wt. measuring signal (w) from the wt. meter 1 and the width (a) of the laminated film by a computer 3. It is judged whether the calculated adhesive coating amount (t) deviates from a predetermined control limit value A and, as a result, when it is judged that the adhesive coating amount (t) deviates from the predetermined control limit value A, an alarm 4 is outputted. Therefore, the control of the adhesive coating amount at the time of the lamination of the laminated film in a lamination process performed manually heretofore can be automatically performed by the processing of a computer 3 without using a special sensor. By this method, the control of the adhesive coating amount is performed accurately and rapidly and the quality of a product is stabilized and work is simplified.

IPC: B65D65/40
Filed: 1990-09-07
Abstract: PURPOSE:To obtain a colorless transparent film for a retort packing material excellent in gas barrier properties and enhanced in heat resistance, strength and flexibility by laminating the first film wherein an SiOx layer and an SiO2 film are successively laminated to the single surface of a base material composed of a flexible plastic film and the second film composed of a flexible plastic film through an adhesive layer. CONSTITUTION:As a raw material for forming a membrane layer, one having high vapor pressure is pref. and SiO is suitable. Next, in order to form the SiOx layer 2 mixed with the structure of a base material, energy of several ten-several hundred eV is applied to film forming particles in an oxygen free atmosphere. Further, when an SiO2 film 1 is formed on the SiO2 layer 2 by vacuum vapor deposition using SiO as a raw material, O2 gas is usually introduced into the atmosphere in order to enhance the degree of oxidation. As the adhesive for laminating the first and second films, an aliphatic urethane adhesive hard to change in its hue and enhancing weatherability is proper. An adhesive layer 4 is formed by applying this adhesive to the first or second film and superposing two films one upon another to cure the adhesive under heating.
