IPC: B65D75/58
Filed: 1994-02-22
Abstract: PURPOSE:To provide a pouring out port for a flexible packaging bag, which has a re-closing property, and of which the cost is kept low. CONSTITUTION:A cap part 3 is connected to the upper edge of a cylindrical part 5 by a thinner part 4 in such a manner that the cap part 3 may close the cylindrical part 5 of a main body part 2 which is equipped with an attaching part 6.

Abstract: PURPOSE:To obtain a heat sensitive recording medium having high thermal response, high sensitivity and less adherence of tailing by providing an intermediate layer containing specific inorganic powder, aqueous adhesive and a specific amount of carboxymethylcellulose as a main ingredient to the adhesive between a support and a recording layer. CONSTITUTION:This heat sensitive recording medium has a support, an intermediate layer and a heat sensitive recording layer containing electron donative colorless dye, electron acceptive compound and sensitizer as main ingredients. The intermediate layer contains inorganic powder of 50ml/100g of oil absorption amount, aqueous adhesive and 3-20wt.% of carboxymethylcellulose to the adhesive as main ingredients. If the quantity of the carboxymethylcellulose is excessive, its paint viscosity is raised, and its sensitivity is deteriorated. Its content is desirably 3-20wt.%. The dye, the compound and the sensitizer of the heat sensitive layer are pulverized together with aqueous soluble polymer compound for use. In order to enhance the sensitivity, the diameter of the pulverized particle is smaller, the better, but, it is excessively small, the adherence of tailing is deteriorated. In combination of the intermediate layer, the adherence of the tailing is reduced with 1.0mum or less of the diameter, thereby obtaining the medium having high sensitivity.

Abstract: PURPOSE:To analyze metallic ions in a wide range by a method wherein the metallic ions in a sample water are condensed by a cation exchange resin, the condensed metallic ions are eluted by an eluting solution, and a reducing agent is added to reduce a part of the metallic ions. CONSTITUTION:A dissolving agent 2 of hydrochloric acid is added by a feeding pump 3 to a sample water fed by a feeding pump 1. The sample water is then sent to a heating device 4, where the clad is dissolved. Thereafter, the sample water is sent to a condensation column 7 of a cation exchange resin by a feeding pump 5 through a switching valve 6. The metallic ions are condensed. When the valves 6, 10 are switched, the metallic ions in the sample water are condensed in a condensation column 11, and at the same time, an eluting solution 8 is fed to the column 7 by a feeding pump 9, so that the metallic ions are eluted. Further, the sample water is sent to a separating column 14 of a cation exchange resin. A reducing agent 12 of ascorbic acid is added by a feeding pump 13 in the column 14. Accordingly, Fe<3+> ions are reduced to Fe<2+> ions. A color producing reagent 15 is added at 16 to the sample water separated in the column 14. The absorbance of the produced complex is quantified by a spectrophotometer 17.

Filed: 1988-02-29
Abstract: PURPOSE:To make an air utilization factor at the time of mixing and stirring fuel and swirl improvable by forming a sectional form of a fuel nozzle hole into a forward expansible, oblong fusiform type. CONSTITUTION:At a tip part of a fuel injection nozzle body 9, a flow dividing chamber 10 is formed inside, and four fuel nozzle holes 12 are installed in a peripheral wall 11. These fuel nozzle holes 12 are formed at regular intervals in the circumferential direction, and each axial center is formed in this peripheral wall 11 so as to become titled downward. Here a sectional form of each fuel nozzle hole 12 is formed that a hole width size (a) in direction of being overlapped with an axial center S of the nozzle body 9 at side view is smaller oblong than a hole width size (b) in the circumferential direction, and a hole width size (a1) at the upstream side in the flowing direction of a swirl in the hole width size (a) in the axial direction is made up in a fusiform type which becomes larger than a hole width size (a2) at the downstream side. With this constitution, an oblong fusiform atomized fuel area, in which thickness at the swirl upstream side is thicker than that at the downstream side, is formed in a combustion chamber.

Title: Ring trip method
Inventor: KINOSHITA KAZUMI
IPC: H04M3/02
Filed: 1990-02-28
Abstract: PURPOSE:To prevent erroneous off-hook detection due to a rush current flowing to a capacitor C of a bell circuit at the transmission of a call signal by providing an effective/ineffective discrimination means which does not discriminate it as the off-hook detection when an off-hook detection signal is not consecutive for a prescribed time to a post-stage of a ring trip circuit. CONSTITUTION:When a rush current flows to a capacitor C of a bell circuit at the transmission of a call signal and a ring trip circuit 1 outputs a pseudo off-hook detection signal in which a part in excess of a threshold level is one level, the output is inputted to an effective ineffective discrimination circuit 2 thorugh a line concentration circuit 13. Even when one level for a shorter period than the period of a clock CLK 1 is inputted, an output of the effective/ ineffective discrimination circuit 2 goes to one level and it is the same as the case of not receiving an off-hook detection signal. Thus, an incoming control signal is not blocked by an AND circuit 24 and the transmission of a call signal is not stopped.

IPC: G06K7/12
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium reproducing device in which an inexpensive light emitting diode(LED) can be used as a light source. SOLUTION: This device is equipped with an LED1 outputting monochromatic light, a pinhole 2 provided with a hole of nearly the same size as a component dot of an image shown by information recorded on a CGH3, a slot 12 formed in a housing so that an optical card 10 may be inserted, and an inspection hole 11 for viewing a virtual image. When the optical card 10 provided with the transmission type CGH3 is inserted in the slot 12, the light outputted from the LED1 passes through the hole of the pinhole 2 and irradiates the CGH3. Since light diffracted by the CGH3 is outputted toward the inspection hole 11 formed on the housing, the virtual image is viewed at the position of the pinhole 2 when a user looks through the inspection hole 11.
