To provide laminated type semiconductor memory devices that can improve the yield of chips without complicating wirings and components. There are provided a plurality of laminated semiconductor chip layers, and chip selection pads provided on each of the chip layers, which are mutually connected across the chip layers, respectively, such that a chip selection signal for selecting each of the chip layers is commonly inputted in each of the chip layers. Each of the chip layers is equipped with program circuits each of which is capable of programming an output signal, and a chip selection judging circuit that judges a chip selection based on the chip selection signal and an output signal of the program circuit. As a result, address information can be set afterwards by the program circuit, such that one kind of chips may suffice in the chip manufacturing stage. Because the chip selection signal is inputted in the common chip selection pads, independent wirings for the respective chips are not required.

The invention discloses a control method of a chemical process intelligent pump, which belongs to a pump control technology, a technological process device for realizing energy conservation of a chemical process pump in the prior art is complicated, and the control method comprises the following steps: writing startup rotational speed N0, writing a flow rate-power performance chart of energy conservation and setting target flow rate Q0 through an initialization module; leading the pump to be started up according to the startup rotational speed N0 and measuring actual power P when the pump operates at a certain rotational speed N1 by a power measuring module; using a control module to compare the measured actual power P with the flow rate-power performance chart to obtain actual flow rate Q when the pump operates at the rotational speed N1, and calculate through a formula that Q0/Q equals N/N1 to obtain rotational speed N when the pump achieves the target flow rate Q0; and using an output module to output the rotational speed N when achieving the target flow rate Q0 to a motor for driving the pump.

According to a method for constructing a cover layer S on a planum M by using a paving screed B the elevation of the paving screed B above the planum M is measured using a reference RZ on the planum M by at least one elevation sensors H and/or the lateral inclination of the paving screed B with respect to the planum M is measured by at least one lateral inclination sensor N. Upon occurrence of a deviation from the target elevation pulling points P of pulling bars 6 of the paving screed B are displaced vertically at a road paver F by levelling cylinders Z. Each levelling cylinder Z is exclusively adjusted over an absolute stroke starting from a selected zero point NP. The absolute stroke is calculated from a measuring result of a reference measurement and by consideration of a construction ratio factor. A new adjustment position of the levelling cylinder Z resulting from the adjustment over the absolute stroke in a self-learning fashion automatically is selected as the new zero point NP for a subsequent regulation cycle.

The invention provides an induction heating cooking device. A strip heater (42) of a tabular heating body (22) emits heat owing to being electrified. The heating-cooking apparatus arranged at a roof (13), such as a pot (17) etc., can be heated directly by the tabular heating body (22). The major part of the heater (42) winded to the insulated substrate does not contact with the substrate (41) except a winding part of the heater (47). Therefore, the heat generated by the electricity does not make interaction between the substrate (41) of different thermal expansion coefficient and the heater (42) even if the heat takes the dimensional change in the heater (42). That is to say, the stress generated in the substrate (41) reduces even if the size of the heater (42) changes owing to the heat. As a result, the damage in the substrate (41), such as crack etc., does not generate owing to the heating of the heater (42) even if the difference of the coefficient between the substrate (41) and the heater (42) is big.
