Filed: 1993-09-08
Abstract: PURPOSE:To generate a micro-differential pressure by connecting a plurality of flow resistance elements having different pressure drops in series and passing a working fluid through the series connection, calculating micro-pressure drop across a low flow resistance element highly accurately, and then driving a pressure drop. CONSTITUTION:A flow regulating section 2 provided at the outlet of a fluid supply section 1 is coupled with a temperature stabilizing section 3 and further coupled in series with low and high flow resistance elements 4, 5. A fluid is then fed, at a set flow rate, from the fluid supply section 2 through the flow regulating section and the temperature stabilizing section 3 to the low flow resistance element 4 and the pressure drop thereat is measured by means of a differential manometer 9. In In order to subject the differential pressure produced at the element 4 to high order correction, as required, pressure and temperature are measured by means of a pressure gauge 8 and a thermometer 7. The fluid flows out from the low flow resistance element 4 to the high flow resistance element 5 and a part thereof is led out through a piping and fed, as a reference, to a machine 6 for which the differential pressure is fed.

Filed: 1993-08-18
Abstract: PURPOSE:To enable a heating operation to be carried out when an abnormal state in a hot water circulation circuit occurs by a method wherein a refrigerant circulation circuit is changed over to the heating operation when an instruction of a rapid heating operation is set. CONSTITUTION:When a heating operation is started, a hot water heating source machine 13 is turned on, both a controlling of a proportional control valve 18 and an operation of a circulation pump 15 are started, and hot water is supplied to a radiator 3. A hot water heat exchanger temperature sensor 25 detects a temperature of the radiator 3, i.e., a hot water heat exchanger temperature and it is judged whether there is an abnormal state in the hot water circulation circuit. Then, when an abnormal state occurs in the hot water circulation circuit, operation of the hot water circulation circuit is stopped and at the same time a heating operation of the refrigerant circulation circuit is started. With such an arrangement as above, it is possible to perform the heating operation even under a condition in which the heating operation with the hot water circulation circuit becomes impossible. When a rapid heating instruction is provided at the time of starting the heating operation, a four-way valve 10 is changed over to a heating operation side under a condition in which the operation of the hot water circulation circuit is continued, the compressor 7 is turned on and the heating operation of the refrigerant circulation circuit is started.

Title: Image display panel and image display device
Inventor: HOSOYA MORIO
IPC: G02F1/13
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To eliminate a visible light absorbing layer in a reflection type image display device, having functions for retaining a displayed state of image information, to prevent distortions of an image when the image is seen from an oblique direction and to enable easier production. SOLUTION: An image forming layer 31 of an image display panel 30 contains an infrared absorbing dyestuff and a liquid-crystalline material which causes phase transition accompanied by changes in the reflectance, when it is heated. The infrared absorbing dyestuff sufficiently absorbs visible light or a visible light absorbing dyestuff is added to the infrared absorbing dyestuff if the dyestuff does not sufficiently absorb visible light. When the image forming layer 31 is irradiated with infrared light, the infrared light absorbing dyestuff generates heat, the phase transition of the liquid-crystalline material is caused to change the reflectance and a visible image is formed in the image forming layer 31 and retained.

Title: Method for extruding molding ceramic and molding device
Inventor: NISHIO MOTOHIDE
IPC: B28B3/20
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To restrain the sideway deviation of the lower part of a ceramic molding and cut the molding to a specified length while preventing the molding from being bent or twisted, by leading straight the molding extruded downwards by means of a guide and at the same time, supporting the lower end face of the molding at a constant load. SOLUTION: A molding 2 extruded from a molding machine 1 is correctively positioned to stand upright by a guide 4 immediately after coming out of a die and then is elongated downward. Thus, the lower end of the molding 2 comes into contact with a jig 3 and, after that, the molding 2 is extruded while pushing back a cylinder 8. In this case, the rod movement of the cylinder 8, i.e., a delivery rate based on a cutting position as a reference is measured based on an output from a linear sensor incorporated in the cylinder 8. When the rod is moved to a specified value, for example, by half the stroke, a straight moving table 7 at an elevator 5 is lowered in accordance with the extrusion rate of the molding 2 measured by a sensor 10. Further, when it is interpreted that the molding 2 is extended to a specified length, it is cut using a cutter 6.
