Title: Hot water boiler
Inventor: INOUE TADASHI
IPC: F24H1/44
Filed: 1983-02-22
Abstract: PURPOSE:To prevent the dewing of exhaust gasses, after-heating, the freezing of boiler water and a supply of high temperature hot water by a method wherein a coil-like tubular heat exchanger is provided on the upper part of the boiler and a mixing tank, the heat exchanger and the upper end of the boiler are made to communicate with one another. CONSTITUTION:A high temperature combustion gas generated by a burner 17 moves upward through a smoke duct 2 and is discharged outside from a rectifying cylinder 9. Water supplied from a water supply pipe 12 is preheated by the combustion gas while it moves up in the boiler and a part of the water enters the heat exchanger 5 from a communication pipe 6 and after being heated sufficiently, it is transferred to the mixing tank. The remaining hot water enters the mixing tank 7 via a bypass pipe 8 and the two parts of the hot water are mixed to be supplied from a hot water pipe 13. In this case, as the preheated water is supplied into the heat exchanger pipe 5, no dewing of the exhaust combustion gas takes place. Further, even when the boiler water in the heat exchanger 5 is heated to a high temperature due to after-heating, it is mixed with the remaing hot water in the mixing tank 7 so that the temperature of the hot water is lowered to be supplied at a suitable temperature.

Filed: 1990-02-08
Abstract: PURPOSE:To sufficiently meet the requirements of a driver by detecting the frequency of switching over to the other speed change patterns from one speed change pattern, and thereby providing a means changing a restoring condition which permits the other speed change patterns to be changed into the aforesaid one pattern in response to the aforesaid frequency. CONSTITUTION:The frequency detecting means 5f of a speed change control means 5 computes frequency based on signals from a speed change pattern switching means 5b, a generating condition for restoring signals generated by a restoring signal generating means 5c is changed when the aforesaid frequency exceeds a specified reference. The change of a condition, for example, permits the opening of a throttle valve for requiring a range B to be changed to a low opening side by a specified quantity, and also concurrently permits a delay in time which causes the restoration of a change pattern in this range, to be lengthened by a specified time. In addition, the 3.5/8 section of the opening of the throttle valve for determining a range (c) is changed to a low opening side by a specified quantity and the delay in time is lengthered by a specified time. Namely, when an operation in a power mode is carried out, frequency for restoring an economy mode from the power mode is thereby lessened.

IPC: G01P3/80
Filed: 1980-03-10
Abstract: PURPOSE:To perform highly accurate speed measurement which does not depend upon the optical properties of surfaces by measuring such time when the characteristics of the luminance distribution of the image of the surface on the upper stream side of a moving continuous object and the characteristics of the luminance distribution of the image of the surface on the lower stream side of fixed distance coincide. CONSTITUTION:The images 3 of the surfaces (a), (b) of a moving continuous object 1 are formed on plural pieces of photodetectors 4 by having a certain luminance distribution by optical systems 2. The outputs of the photodetectors are inputted in arbitrary pair into a differential signal generator 5, by which they are made into the signal showing local uneven luminances. These are sampled in a sample holding circuit 6 according to the sample pulse from a timing circuit 9 and are stored until the next pulse. The signal proportional to the absolute value of the difference between this signal and the continuous uneven luminance signal on the lower stream side is obtained by an absolute value circuit 7, and the sum total of this signal is obtained with a sum signal generator 8. If the time from the sample pulse from 9 till the minimum value of the sum total output, that is, the moving time from (a) to (b) is known by a minimum value detecting circuit 10, the speed is obtained.

Filed: 1986-02-13
Abstract: PURPOSE:To extract flow rate pulses with high resolution, to remove an error due to the reversing of a rotator, and to output accurate flow rate pulses by performing the addition, subtraction, and integration of output backward rotation pulses and forward rotation pulses which are outputted later. CONSTITUTION:Pluse generating circuit parts (U1-U2 and D1-D2) extract pulses which synchronize with the leading and trailing of A-phase pulses and have a pulse repetitive frequency twice as high as the A-phase pulses. Then, forward rotation pulses are outputted from a gate as flow rate pulses and when backward rotation pulses are outputted, the gate is closed to stop the output of the flow rate pulses, so as to remove an error. Namely, reverse current error removing circuits (FF circuits 12 and 15), etc., stop the output of the number of backward rotation pulses and the output of forward rotation pulses as many as the backward rotation pulses to eliminate repetitive metering due to the reflow of fluid which flows backward and measure only the actual flow rate, so the accurate flow rate is measured.
