Abstract: PURPOSE:To shorten the cycle time of write on memory by comparing the row address of a write operation immediately preceding with that of the next write operation, and executing page mode write when coincidence is obtained between them. CONSTITUTION:An address comparator 14 compares a preceding address with a succeeding next address, and outputs a comparison signal when the coincidence is obtained between the row addresses of them. A timing control circuit 34 inputs the comparison signal, and performs control so as to switch the output of an address multiplexer 35 to the row address and a column address, and outputs it to a storage part 6. The start and stoppage of an operation are performed fitting in a timing signal to set the column address at the storage part 36, and the write of the output of data in a write data register 33 is performed with the same timing. In such a way, it is possible to shorten the cycle time of the write on the memory.

SOLUTION: A warm-air outlet port 5 is provided on the long side of a bathtub 10 and sent-out warm-air flows out horizontally downward so that the center line 21 of the warm-air is provided with an angle α and arrives at the wall 1 of a bathroom, then, is distributed into upper direction and lower direction while much of warm-air flows downward. The downwardly distributed warm-air is reflected at a washing place 18 and flows upward. Thus, the warm-air is mixed complicatedly in the washing place 18 and is ascended, then, is sucked through a suction port 13. Warm-air flows obliquely downward immediately above the level of hot-water 11. Accordingly, the warm-air entrains much amount of water vapor, rising up from the level of hot-water 11, while a warm-air temperature is raised suddenly by the enthalpy of the water vapor.  The hot-air temperature in the upper and lower parts of the washing place 18 is raised in a very short period of time and preliminary heating is finished in such a manner.

Filed: 1993-03-19
Abstract: PURPOSE:To decide a line segment in short calculation time without damaging linear detecting ability originally provided for Hough transformation by performing the Hough transformation to a straight line passing a certain point with that point as an origin. CONSTITUTION:The source straight line is detected from points 30-35 linearly distributed on an X-Y plane, and that is a straight line 36. In this case, when the foot of a perpendicular from an apex O to the straight line 36 is defined as H, the condition of OH=taur is established, an angle formed by the OH and an X axis is defined as thetaand the coordinate of H is defined as (x, y), the straight line 36 is expressed by a prescribed polar coordinate. When the rho and theta are parameters, the group of all the straight lines passing a certain point (x, y) is shown by a prescribed expression. Thus, since Hough transformation is performed with the line segment as the origin in the case of deciding that line segment, the number of times of transformation is reduced just for one time in comparison with the general Hough transformation of a point to be calculated and it is enough for the result of Hough transformation just to investigate only the maximum and minimum values of rho. Therefore, the process of calculation is simplified and arrangement to be used or the calculation time can be reduced.

At this time, when a liquid floating object such as an oil or the like exists on the surface of the water, the valve of the energy amount of the reflected infrared rays 15 differs by depending on whether the radiant infrared rays 14 are reflected by the surface of the water of by the liquid floating body. Then, the reflected infrared rays 15 are emitted on respective pixels which are arranged two-dimensionally on an infrared detector 10, and an analog pixel signal 16 is output. The analog pixel signal 16 is converted into a digital pixel signal 17 by an A/D converter 11 so as to be input to a comparator 12.  The comparator 12 compares the digital pixel signal 17 with a threshold value, a result is output to an alarm 15 as a binarized signal 18, and a warning is sounded when the binarized signal becomes a value meaning the detection of the floating object.
