Abstract: An automatic steering control system comprises a behavior detector, a pattern matching section and a control parameter setter. The behavior detector sequentially determines a time duration of each of specific kinds of behaviors of a ship based on heading data detected by a heading sensor. The pattern matching section sequentially determines a behavior pattern which each of the behaviors of the ship matches from among multiple behavior patterns based on the heading data detected by the heading sensor during the time duration of each of the behaviors sequentially determined by the behavior detector. The control parameter setter sequentially reads out control parameters stored in a memory in correlation with the behavior pattern which each of the behaviors of the ship matches as determined by the pattern matching section and controls the ship based on the control parameters read out of the memory.

Abstract: A control system of the invention for regulating a quantity to be controlled based on a deviation of the controlled quantity from a target value thereof and control parameters includes a behavior feature value calculator, a basic state judgment data calculator and a control parameter setter. The behavior feature value calculator detects the period or frequency of behaviors of a specific kind performed by a subject to be controlled. The basic state judgment data calculator calculates the amount of variations in the aforementioned period or frequency. The control parameter setter updates the value of at least one of the control parameters based on the amount of the aforementioned variations.

Abstract: This invention concerns a heating pipe for panel heaters disclosed on walls, ceilings or floors to heat a room. The pipe is essentially constructed of a pipe itself, an electric heating wire running through it and aluminum granules stuffed between the two. Because of the simple structure, the production, the installment and the maintenance costs are cheap; as a matter of course, there is no additional need of a circulation pump for heating media and safety devices to watch the leak of heating media or the break of the pipe. Moreover, because spherical aluminum granules are closely packed, the heat conductivity is very good, which minimizes the heat loss and reduces the time to heat up a room. Also, the heat capacity is so small that frequency room temperature control by means of an automatic on-and-off mechanism has becomes possible.

Abstract: This invention concerns an elevator provided with an elastic member. The elastic member, by and large triangular in cross section, is attached to every exit of an elevator: an end of each floor inside a vertical path in which a cage ascends and descends or a floor end of a cage so as to stuff a gap at every exit. Therefore, even if passengers carelessly drop their small article, it is prevented from escaping from the gap. Other than that, women's high heels and children's shoes are prevented from getting into it; likewise, the wheels of loaded trucks do not get into it. The elastic member, designed to be a shock absorber, gives a cage no substantial shock even when the cage strikes against it a little.
