With low pressure vapor there is no trouble of a secondary disaster even if a person is wet, and provided a person gets wet, the vapor is easily found because its being white and also a repairment is eased. In addition, provision of a treated water supply piping 4 permits the use of a water supply line of another system other than public water supplies to hereby improve safety upon any disaster.  Further, also for district heating safety and security are ensured because hot water supply is achieved only by mixing vapor with treated water.

Abstract: PURPOSE:To make highly accurate measurement of speed possible by making an optical system irradiate an object to be measured in the waste area in which laser beam is in the state of convergence and considering influences of not only variation of optical coefficients but also variation of light receiving level. CONSTITUTION:Output power of a semiconductor laser 12 is controlled by an automatic power control circuit 11 to become constant at all times.

Scattered light from the object 10 including a speckle pattern is received through a screen having a finite opening and converted to electric signals. The output electric signals are sent to a signal processing circuit 6. Accordingly, influences given by variation of object distance to coefficients of an optical system and influences given to the level of the light receiving signal offset each other, and therefore, speed can be measured at high accuracy.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide an electronic control type mechanical clock that can report time delay to a user and enables the user to use the clock while time has been delayed. SOLUTION: An electronic control type mechanical clock is provided with a rotation control means 50 for controlling the rotation cycle of a generator 20 for converting a mechanical energy from a spring 1a to an electrical energy. The rotation control means 50 performs brake control for regulating speed when the value of an up/down counter 54, where a rotation detection signal FG1 corresponding to the rotation cycle of the generator 20 and a reference signal fs are inputted, reaches a first setting value since the rotation cycle of the generator 20 becomes faster. Also, when the value of the counter 54 reaches a second setting value since the rotation cycle of the generator 20 becomes slower while the generator 20 is not braked, brake control for stopping the handling of a needle is made.  When the rotary speed of the generator 20 slows down and the handling of the needle is delayed, the handling of the needle can be stopped or extremely slowed, thus enabling a user to recognize the abnormality of the handling of the needle.
