Title: Quantitative determination of iron in water and reagent for quantitative determination to be used for there
Inventor: KANEDA TAKAYUKI
IPC: G01N31/00
Filed: 1984-12-26
Abstract: PURPOSE:To make the quantitative determination of the iron in water with a stable and simple operation possible by ionizing and dissolving the insoluble iron in the water by a solid ionizing agent then making quantitative determination by using an iron ion color former. CONSTITUTION:The insoluble iron in the test water is ionized by using a boric acid, etc. and the alkali or alkaline earth metal thereof, ammonium salt, alkanol- amine salt, etc. as the solid ionizing agent and the valency of the iron ion is averaged to tervalent, bivalent, etc. by an oxidizing agent or reducing agent. The iron ion is then colored by using a bivalent iron ion color forming agent, etc. such as O-phenanthroline. The iron ion concn. is determined when the color is visually observed in comparison with a standard color index. The need for a pretreatment such as boiling under addition of a mineral acid and spectrochemical analysis, etc. is therefore eliminated and the quantitative determination of the iron in the water is made possible with the stable and simple operation.

Title: Ceramic coated exhaust valve and its manufacturing method
Inventor: WATANABE MASAOKI
IPC: F02F7/00
Filed: 1984-12-26
Abstract: PURPOSE:To prevent the generation of a nonuniform crack on an exhaust valve by affixing a ceramic sheet, provided with a channel as the starting point of the crack generation, to the fire contact surface of the exhaust valve. CONSTITUTION:A ceramic sheet 13, provided with a channel 14 as the starting point of crack generation on at least one main surface, is affixed to the fire contact surface of the valve body of an exhaust valve 10. And, the present surface is coated as required, or the surface after the generation of a crack is coated. Thereby, the generation of a nonuniform crack due to the temperature changes can be prevented, and the generation of only a uniform crack, free from the problems, such as the peeling or breaking off an a part of the ceramic layer, is permitted so that a breakage due to the thermal stress under elevated temperatures can be prevented substantially.

Title: Rotary head type magnetic recording and reproducing device
Inventor: SASAKI YOSHIYUKI
IPC: G11B5/02
Filed: 1986-11-20
Abstract: PURPOSE:To obtain a normal reproducing signal even with a slip ring or a brush worn or damaged by making a switching element conductive only when a head does not scan a tape so as to charge up a power smoothing capacitor. CONSTITUTION:Since a power switching pulse being an LO level is fed to a base resistor 10 during a period when the head does not scan a tape, a transistor (TR) 9 is conductive and the power smoothing capacitor 4 is charged up to a Vcc [V] being a power voltage momentarily. While the head scans the tape, since the power switching pulse goes to an HI level, the TR 9 is opened, a head amplifier 2 is operated by a power current loop formed in a rotary drum only and using the charged electric charge of the power smoothing capacitor 4 as the power to make the slip ring and brush independently of the reproduction. Thus, even with the slip ring and brush having some flaw, no noise appears at an output of the head amplifier 2.

Title: Commodity storage and discharge device for vending machine
Inventor: OTSUKA YUJI
IPC: G07F11/42
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To improve the commodity storage efficiency of an vending machine by discharging commodities via a commodity path of a horizontal commodity rack to the oblique front lower side. SOLUTION: When a commodity S is ready to be sold, a pusher 14 and a flapper 16 are located at a standby position and a horizontal holding position respectively with an engagement pin 16c positioned at the rear end of a groove M2. Under such conditions, many commodities S are held between a pressurized member and a stopper 13. In a sales made, the commodity S is guided by the flapper 16 and discharged to the oblique front lower side via a tilting part 13c of the stopper 13 of a commodity rack placed right under the flapper 16. Thus, the commodity S is discharged to the oblique front lower side from the horizontal commodity rack and accordingly will not hit nor catch the commodity rack of the lower part.  As a result, many horizontal commodity racks can be arranged vertically in a vending machine without hindering the sales of the commodities S and then the spaces can be used effectively in the body of the vending machine.

Title: Parts delivery instructing device
Inventor: INUI HIROYUKI
IPC: G06F19/00
Filed: 1989-10-30
Abstract: PURPOSE:To evade such a case where the delivered parts are kept in custody for a long period at the assembly line side by changing automatically the ordering instruction from to a fixing instruction when the number of parts desired is decreased owing to the fluctuation of demand. CONSTITUTION:A sheet number calculation means 81 calculates the number of ordering instruction cards based on the number of parts required given from a production planning means 51. A 1st comparison means 82 compares the calculated number of ordering instruction cards with the number of ordering instruction cards set previously. At the same time, a 2nd comparison means 83 compares the parts delivery read time with the parts use read time. Then the ordering instruction form of parts is switched to a fixing instruction which designates the delivery time when the calculated number of cards is smaller than the set number of cards and the delivery read time is shorter than the use read time. Thus the delivery of parts is possible in accordance with the fluctuation of demand and to evade such an inconvenient case where the delivered parts are not used for a long period.

IPC: C11D7/54
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a cleansing agent capable of being simply used, giving sufficient cleansing effects, and used for concretes or pillar trees. SOLUTION: This cleansing agent comprises one or more kinds of oxygen bleaching agents selected from hydrogen peroxide, peroxoborate salts, peroxocarbonate salts and peroxosulfate salts and a coating film-forming material. The cleansing agent is dissolved in water and/or a lower aliphatic alcohol, and the dissolution mixture is coated on an application surface to form a coating film. Thus, it is utilized that the bleaching agent component in the coating film contacts with stained parts, and a sufficient cleansing effect is given. The cleaning agent does not drip down when coated, and the stains can be removed only by peeling the coating film after the cleansing. The use of the cleansing agent is therefore extremely simple.  The coating film-forming material is selected from polyvinyl alcohol, polyethylene glycol, a vinyl acetate polymer emulsion, polyvinylpyrrolidone, polyacrylic acid, alginic acid, cellulose, starch, pullulan, etc.
