Abstract: To alleviate or eliminate a problem of unburned fuel discharged to the outside of a cylinder in a case in which an air fuel mixture is insufficiently combusted in a combustion chamber. During the expansion stroke in which a high voltage is applied to an ignition plug via an ignition coil, and a spark discharge is caused to occur at the ignition plug, thereby the air fuel mixture in the combustion chamber is ignited and combusted, in a case in which deterioration of combustion state is detected, a microwave electric field is created in the combustion chamber prior to an opening timing of an exhaust valve at an end stage of the expansion stroke, thereby plasma is generated and enlarged in the combustion chamber.

Abstract: Measuring equipment is equipped with: a measurement container having formed therein a chamber to be measured, into which a gas to be measured enters, and an inlet passage, through which the gas to be measured is introduced into the chamber to be measured; and a connection structure which, when a plug is not mounted to a plughole that opens into a combustion chamber in an internal combustion engine, connects the inlet passage to the plughole. The measurement container may be provided with a plasma generation device, which generates plasma in the chamber to be measured, or a mounting structure for mounting a heating device, which heats the gas to be measured in the chamber to be measured.

Abstract: The invention provides high sensitivity bioassay sensor systems in which non-specific adsorption of impurities such as, for example, proteins, in biological samples is inhibited. Polyethylene glycolated particles enclosing metal or semi-conductor which is in common with the sensor material are used for amplification.

Abstract: While modules to be tested in one constant temperature oven are tested by providing a plurality of constant temperature ovens, accommodating a plurality of modules to be tested in each constant temperature oven and connecting the modules to be tested accommodated in a plurality of constant temperature ovens to the measuring instruments via the switches, preparation for testing such as temperature change of the other constant temperature oven is conducted and the modules to be tested in one constant temperature oven are tested using measuring instruments. Thereafter, the switches are changed over and the modules to be tested accommodated in the other constant temperature oven are tested. Thereby, expensive measuring instruments can be used effectively.

Abstract: According to the invention, a novel laminated fabric sheet of excellent air permeability and a method for producing the same are provided. The laminated sheet comprises a first base fabric including spun yarn and having previously been treated with a water and oil repellent, a rubber composition layer formed on the first base fabric and having a multitude of fine air passages therein and a second sheet of base fabric laminated on the rubber composition layer. The base fabric which has been treated with the water and oil repellent prevents the coated rubber composition from reaching roots of whisker fibers of the spun yarn in the base fabric and fine cells are thereby formed around the lower portion of the whisker fibers. Subsequent heating of the laminated sheet of fabrics for curing the rubber composition causes these fine cells to be inflated to form air passages through the cured rubber composition layer.

Abstract: A rubber coated fabric comprises a base fabric and a coating material laminated on at least one side of the base fabric. The coating material comprises, as its main ingredient, a product of reaction between liquid rubber and polyisocyanate. According to the invention, there are also provided methods for producing the rubber coated fabric comprising steps of mixing and stirring liquid rubber and polyisocyanate together in a mixing-dispensing machine and coating the mixed liquid rubber and polyisocyanate on a base fabric either directly or by means of a release paper or film. According to the invention, curing of the coating material is performed in a low temperature of 120.degree. C. or below resulting in various advantages including saving of energy consumption, prevention of curling of the product and of volatilization of low-boiling point ingredients.

Abstract: A process for producing a dyed finely divided hardened resin of uniform particle size excelling in dispersibility which comprises, in combination, the steps of reacting benzoguanamine with formaldehyde in a ratio of 1.0 mole of the former to 1.2 - 3.5 moles of the latter in an aqueous medium at a pH ranging between 5 and 10 to prepare an aqueous liquid of a soluble and fusible resin having a degree of modified water tolerance of 0-150%, preparing an aqueous emulsion of a dyed soluble and fusible resin by using said aqueous liquid, a dye and a protective colloid, adding to the thus prepared aqueous emulsion in a ratio of 1 - 15 parts by weight per 100 parts by weight of the soluble and fusible resin of ultramicroscopic silica of a specific surface area as measured by the Brunauer, Emmett and Teller Method in the range of about 50 m.sup.2 /g to about 400 m.sup.2 /g and a particle size in the range of about 0.005 to about 0.
