Abstract: A optimal temp. of food in the food container  is  maintained without energy supply for a long time by using the thermal storage material, e.g. laulic acid, palmitic acid,  paraffin  wax,  candle wax,  etc.. A  food  quantity  and   thermal   storage   material requirement in the food  container  for  maintaining  the  optimal temp. of  food is  calculated  by  the  following  equation.  The equation is M = M'(C/P)(Tg-Tr) [(exp(KDt)-1/exp(KDt) + 1   = αM'. In the equation, M is thermal storage material requirement (g), M' is food quantity (gr) , C is specific heat of food (cal/gr. deg.C).

Abstract: The device for detection of rotation comprises m proximity detectors (L0, L1) intended to detect the passing of a mark which is integral with the turning element. The change in the signals delivered by each of the detectors of a selected series of m-1 detectors is analysed (12a). As soon as the mark has been detected at one of the detectors situated at the end of the series, the index of the number of turns (12b) is incremented, a new series of m-1 detectors excluding the one which has just detected the passing of the mark is selected, and the criteria representing the change are re-initialised for the signals to come from the new series selected. There is thus obtained an adaptive system applicable to the detection of rotation of a turbine of a water meter.

Abstract: The method of manufacturing DRAM comprises the steps of : isolation by forming a rectangular trench(T) and a field oxide(42); removing the electrode layers(43,45) and a dielectric layer(44) on top and bottom of the trench(T) by etching after forming a capacitor by forming a plate electrode(43), the dielectric layer(44) and a storage electrode(45) on the surface of the trench(T); removing the electrode layers(43,45) and the dielectric layer(44) formed on the edge of the trench(T); forming an insulating film(46) and exposing the top of the storage electrode(45); filling the trench(T) with an epitaxial layer(141), and forming an insulating film(142) and a CVD oxide film; forming a gate oxide(144); photolithography processing after forming a transistor, a second interfacial insulating film(147), a contact part and a plate electrode(148); and photolithography processing after forming a third interfacial insulating film(150), a bit line contact part and a bit line electrode(151).

Title: Elevator door control apparatus
Inventor: LEE JONG-CHOL
IPC: B66B13/14
Filed: 1992-05-30
Granted: 1994-04-09
Abstract: The elevator door controller comprises a motor, first and second rectifying circuits, a door open/close controller for controlling the open/close of an elevator door, a timer for setting a delay time to reduce noise and impacts, an elevator door position detecting circuit for receiving the delay time of the timer and outputting a speed increasing/decreasing input signal, an operational amplifier for modulating and amplifying the pulse amplitude of the speed increasing/decreasing signal, a motor driving circuit for outputting a driving signal for the motor, and a safety monitor for turning off a safety monitor relay and displaying an alarm signal, thereby making the elevator door open/close smoothly.
