Title: Device for detecting depth of water in deep well
Inventor: ANDOU SUMIO
IPC: E21B47/04
Filed: 1979-03-16
Abstract: PURPOSE: To detect the depth of water from the saturation temperature of a sealed liquid continuously by using a vacuum container in which a liquid is sealed and a liquid heater and a thermometer are installed.  
     CONSTITUTION: When the outer cylinder 1 is attached to the pump in the bottom of the excavated well, the water pressure in the place acts on the pressure plate 11 through the hole 2 of the sensor chamber 3, and balances the pressure of saturated vapor in the vacuum container 5, the thermometer 7 inticates the saturation temperature. Next when the heated water in the container 5 is cooled, its temperature drops, the pressure plate 11 is raised by the water pressure, the operating rod activates the limit switch 9, the liquid heater 6 heats the water, the pressure of saturated vapor increases, the pressure plate 11 is pushed downwards and returned to the balancing location again. In this way, the water pressure can be calculated from the saturation  temperature of sealed heated water to know the depth of water by converting the calculated result.

Title: Concrete placing work for concrete mat
Inventor: YAMAOKA KAZUMI
IPC: E02D17/20
Filed: 1982-02-27
Abstract: PURPOSE:To construct a given thickness of concrete mat by packing a filling material into a bag through a concrete pressure-feeding pipe under gravity or by a pump while pulling up the pressure feeding pipe in order. CONSTITUTION:An upper open type cloth bag 2 is placed on a base, e.g., soft ground 1, etc., and a concrete pressure-feeding pipe 15 is inserted into the upper opening 5 of the bag 2 until its tip reaches near the bottom 17 of the bag 2. Then, a filling material, e.g., concrete, etc., is packed into the bag 2 under gravity or by a pump while pulling up the pressure feeding pipe 15 orderly. Thus, since motion energy is very small and resistance is less during the packing period, little and no effect exerts on the bottom of the bag during the packing  period, and therefore, a given thickness of concrete mat can be constructed without causing any degradation of shape.

Title: Screen printing machine
Inventor: ASAI KOUICHI
IPC: H05K3/12
Filed: 1992-01-21
Abstract: PURPOSE:To embody easy operation for bringing a squeegee into contact with a screen with an appropriate pressure by a method wherein a device for touching and separating the squeegee is composed of two air cylinders connected to two locations, distant from each other in the longitudinal direction of the squeegee, and control devices which control separately air pressures to be supplied to the air cylinders. CONSTITUTION:In the case where a first squeegee 112 is used in execution of printing, air is supplied to chambers in the upper parts of air cylinders 114 and 116 by operation of control by a control device while chambers in the lower parts are opened to the atmosphere, and thereby the first squeegee 112 is lowered and is brought into contact with a screen. As the weight of an ascending/descending part 117 of the first squeegee is offset by the force of a spring 170 in the course of lowering, the first squeegee member 154 comes into contact with the screen only by air pressure supplied to the cylinders 114 and 116. Since the structure is so constructed that the squeegee member 154 can be brought into contact with the screen with desired pressure regardless of the weight of the ascending/descending part 117, air pressure supplied to the cylinders 114 and 116 is controlled by the control device so that the squeegee member 154 can be brought into contact with the screen by the desired pressure.

The honeycomb coat is dipped in iridium chloride (2.88g IrCl4 .H2 O/200cc of H2 O) and impregnated for 1hr, the liq. depositing on the substrate wall is scraped off, and the coat is dried at 200 deg.C. The coat is then purged with a nitrogen atmosphere at 500 deg.C to obtain a honeycomb catalyst. The SO3 discharged from the boiler waste gas, etc., is removed in this way.

Title: Weighing meter
Inventor: SHIMOKAWARA EIJI
IPC: G01G23/01
Filed: 1979-03-20
Abstract: PURPOSE: To enable accurate weighing to be done even in places where there are many vibrations and oscillations by so connecting a pair of fluid pressure responding elements as to differentially fetch out their outputs, placing a material to be weighed and a reference weight on each of the elements and weighing the weight by the output difference from boty elements.  
     CONSTITUTION: As a material to be weighed W and a reference weight Ws are placed on respective weighing pans, pressure receiving bellows 1a, 1b form the fluid pressures corresponding to their weights. When there is a difference in the fluid pressures of the both fluid chambers 2a, 2b, a partition plate 2c is moved according to said difference so that the pointer 3 connected to the partition plate 2c is rotated. Hence, the scale indicated by the pointer 3 shows the weight difference of the material to be weighed W and the reference weight Ws. At this time, the influences by vibrations, inclination, acceleration, etc. occur similarly in the both weighing systems, and the influences appear in the indication of the pointer 3 as well but since these occur only with the portions for the weight differences between the material to be weighed W and reference weight Ws, errors are small. In this way, the weighing may be done accurately even in places where there are many vibrations and oscillations.
