Abstract: PURPOSE:To facilitate management of temperature of hot-water in a hot-water reserving tank by indicating under converting into the volume of hot-water diluted by water so as to obtain a temperature in accordance with a using purpose. CONSTITUTION:A total heat amount (a) with respect to an average temperature t( deg.C) in the hot- water reserving tank 1 is detected from the terminal of a sensor A as the output voltage V1 thereof. The total heat amount (b) in case the tank 1 is fully filled with supplemented water having a normal temperature T0( deg.C) is detected as the voltage V2, which is (n) times of the output voltage thereof when it is taken out of the terminal B of an element A1 near a water receiving port in case the element A1 is consisting of (n) pieces of temperature detecting elements having the same characteristic. Further, when a reference hot-water temperature upon bathing is 45 deg.C and the output voltage with respect to the total heat amount (c) in case the tank 1 is filled fully with the water having the reference temperature is V3, the following formula with respect to the relation of temperature-amount of hot-water can be replaced to the relation of heat amount-output voltage. Therefore, a formula; (a-b)/(c-b)=(V1-V2)/(V3-V2) is obtained and the volume X of the remaining hot-water converted into the reference temperature may be determined by multiplying it by the total capacity (d).

Title: Method and device for controlling double atrial triple chamber cardiac pacemaker having fall back mode
Inventor: MARUSERU RIMUJIN
IPC: A61N1/368
Filed: 1995-04-05
Abstract: PURPOSE: To obtain a triple chamber cardiac pacemaker like the one which can energize a fallback mode by keeping a risk of malfunction to a minimum. CONSTITUTION: A cardiac pacemaker is equipped with a right atrial electrode 4 and left atrial electrode 4 connected to the same atrial detection/stimulus circuit and a ventricular electrode 3 connected to a ventricular detection/stimulus circuit. A fallback mode non-synchronizes a ventricular stimulus from the detected atrial rhythm when the atrial rhythm is too fast. Further, the time of period for adjustment in the fallback mode is included in that a ventricular stimulus is successively re-synchronized with the atrial rhythm when the atrial rhythm is lowered to a slower rhythm. Thus, in the atrial circuit successive signals are detected and a shut-off time of transmission between atria to be regulated during which the signals are not detected by the atrial circuit in response to each detection.  The time interval to separate the detection signals is measured and the time interval is compared with a specified comparison value. When the measured time interval becomes greater than the comparison value, a fallback mode for re-synchronization is successively initiated.

IPC: B65G5/00
Filed: 1982-05-13
Abstract: PURPOSE:To enable to store a high pour point oil in the cave in bed rock, by a method wherein when storing a hydrocarbon oil (which is solidified at normal temperature) or the like in the cave in an underground bed rock, a water bed is provided at the bottom part of the cave, the oil or the like is stored by floating it on the water bed, and is fed out by fluidizing the oil or the like by heating the bottom of the water. CONSTITUTION:The water bed 3 is formed by placing water in the cave formed by a bed rock storing tank 1 under ground base (which is formed by excavating the bed-rock 5) and a bottom plate 4. When a high pour point oil 2 fluidized by heating to a temperature of not lower than its pour point is placed into the cave, a solidified oil film is instantaneously formed at the interface between the oil 2 and the water bed 3, and then the oil film is gradually enlarged in thickness. In this case, the lowering rate of temperature of a central part is low, and the oil 2 can be stored stably for a long period of time. When feeding out the oil 2, the temperature of the water bed 3 is raised to heat the oil 2 from the oil-water interface, whereby the entire body is fluidized and is liquefied through generation of convection, and the oil is fed out. Accordingly, the high pour point oil can be stably stored in the cave in a bed-rock and fed out.

Title: Fuel injection controlling method
Inventor: SUGIMOTO NAOTO
IPC: F02D41/04
Filed: 1985-04-16
Abstract: PURPOSE:To make an air-fuel ratio controllable to the desired one even in any state such as acceleration and/or constant speed or the like, by compensating a maximum fuel injection timing interval at each injection according to an engine running state. CONSTITUTION:A fundamental fuel injection quantity (or a fundamental injection timing range Tp of a fuel injection valve 7) is calculated from an engine speed N and a suction air quantity Q and stored in a random access memory. Likewise, a fuel compensation factor is calculated from cooling water and suction air temperature and stored in this RAM. At the time of normal running, since an air flow meter is normally works, the fundamental injecting timing range Tp is used. However, at the time of high load running, the timing range Tp grows larger than a value of a maximum fuel injection timing range TpMAX corresponding to a desired air-fuel ratio whereby it becomes overrich. Accordingly, the timing range TmMAX set at each engine speed is set down to the fundamental fuel injection timing range Tp in place of this timing range Tp and thereby the air-fuel ratio is controlled. With this constitution, a proper fuel injection is controllable at the whole range of engine operation.
