Abstract: An automatic toilet flushing system which detects when a user sits on the toilet for use and, instead of operating a flush handle for flushing, performs flushing in association with the user's action of standing up to leave the toilet. A forced flushing sensor is also provided so that water can be flowed for flushing through deliberate action of the user.

Abstract: A urine detection device is disposed to a urine receiving surface of a toilet stool in which urine, diluting water and reagent are mixed by vertically moving a piston in the cylinder of the detection device, the reaction between them is detected by an electrode and the ingredient in urine is detected. Liquid in the cylinder is stirred by a stirring device to blown air into the reagent reservoir, by which oxygen is dissolved in the reagent. Cleaning liquid is sprayed from the nozzle to the electrode for flushing. An opening is disposed to a supporting wall of the toilet stool, through which the cylinder is detached or attached. The electrode is disposed such that its rear end is directed to the opening and detached or attached through the opening.

Abstract: An apparatus for examining urine for certain constituents thereof includes a vertically disposed cylinder for receiving urine therein. The cylinder includes a diametrically enlarged upper portion having an inside diameter which is larger than that of its remaining portion. A piston is vertically movably disposed in the cylinder. If the piston is lowered, urine can be stored in the cylinder. If it is raised, the urine is discharged from the cylinder, except that only a small portion thereof remains in a clearance defined between the piston and the diametrically enlarged portion of the cylinder. If the piston is lowered again, a reagent and water are supplied into the cylinder and mixed with the urine remaining therein. An electrode is connected to the cylinder for determining the concentration of sugar, etc. in the urine which has been mixed with the reagent and water.

Abstract: A method and an apparatus for measuring the concentration values of constituents of urine collected in a toilet bowl. A conduit extends from the urine-collecting portion of the bowl to a concentration-measuring device. A gas injector is mounted beside the conduit to intermittently inject gas into the conduit, for dividing the urine contained in the conduit into aliquots. The concentration values of urinary constituents of each aliquot are measured.

Abstract: A method of driving an automatic on-off valve for a water passageway uses the automatic on-off valve including an electromagnetic valve for opening and closing the water passageway, a sensor unit for detecting an object such as a man or a human hand and a control unit for controlling supply/cut-off of driving electric power supplied from a power supply to the electromagnetic valve in response to a signal transmitted from the sensor unit. The method comprises the steps of: permitting the control unit to control an operation of the electromagnetic valve in a normal state; manually supplying the electromagnetic valve with the driving power given from a manual driving unit connected to the electromagnetic valve; and thus forcibly driving the electromagnetic valve.

Abstract: An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) a reaction product of a novolak-epoxy compound and an unsaturated monocarboxylic acid, (b) a reaction product of a diisocyanate and a poly(meth)acrylate having a hydroxyl group per moleucle and (c) at least one of an aromatic, aliphatic or alicyclic polybasic acid (or an anhydride thereof).

Abstract: A control apparatus for water temperature and water flow rate includes a mixing valve adapted to be supplied with hot water and cold water from a hot water source and a cold water source, respectively, and delivers mixed water. In addition, the control apparatus includes a flow rate controller disposed to a system for delivering the mixed water from the mixing valve to a place where it is required and a controller for operating the mixing valve and the flow rate controller.

Abstract: Water and hot water from a water storage tank and a hot water storage tank, respectively, are mixed in a mixing valve, are pressured up by a pump, and outflow from a shower head. The motor for the mixing valve and the pump are driven so that a signal is output from the controller to the regulator of the motor for altering the mixing ratio of hot water to water in the mixing valve and the regulator of the pump thereby to obtain objective water temperature and water pressure.

Abstract: A steam sauna has a passage for circulation of air existing in a sauna booth, and is provided with a heater for heating air flowing through the passage, and a steam generator with an ultrasonic oscillator for mixing steam generated with the air heated.

Abstract: An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) the reaction product of a novolac epoxy compound and an unsaturated monocarboxylic acid with (b) the reaction product of a diisocyanate and a poly(meth)acrylate having one hydroxyl group for each molecule.
