Abstract: Two layers in each of which a plurality of rod-like permanent magnets each having a width Wm, a thickness Tm and a predetermined length are aligned on a plane in such a way that they have opposite magnetic pole orientations alternately and are aligned at a fixed pole pitch ?p are arranged to be opposed to each other with the magnetic pole orientation of each magnet in one of the layers being identical to that of the opposing magnet in the other layer, and with the opposing surfaces of the magnets being spaced a distance 2×lg apart from each other, and a vibrating membrane on which coils each having a conductive pattern are arranged is placed in a gap between any two adjacent rod-like permanent magnets in each of the above-mentioned two layers. The arrangement of the rod-like permanent magnets is optimized by using Wm, Tm, ?p, and lg.

Abstract: A therapeutic exercise apparatus enables a user to depress a pedal by his or her heel without his or her foot coming off the pedal. The apparatus includes a main body, a link having one end mounted through a rotation shaft on the main body so as to be rotatable around its one end by a predetermined angle, a pedal mounted on the other end of the link so as to be rotatable by a predetermined angle and adapted to be depressed by a user's foot thereby to rotate the link; and a foot restraining member provided on the pedal for restraining the foot. The foot restraining member has a base provided with a heel support portion for supporting a heel of the foot, and the heel support portion is disposed on the pedal such that the direction of a depression force of the foot passes through the rotation shaft.

Abstract: During data reading, a sense enable signal is activated to start charging of a data line prior to formation of a current path including the data line and a selected memory cell in accordance with row and column selecting operations. Charging of the data line is completed early so that it is possible to reduce a time required from start of the data reading to such a state that a passing current difference between the data lines reaches a level corresponding to storage data of the selected memory cell, and the data reading can be performed fast.

Abstract: Normal memory cells and dummy cells are arranged continuously in a memory array. In a data read operation, first and second data lines are connected to the selected memory cell and the dummy cell, respectively, and are supplied with operation currents of a differential amplifier. An offset corresponding to a voltage difference between first and second offset control voltages applied from voltage generating circuits are provided between passing currents of the first and second data lines, and a reference current passing through the dummy cell is set to a level intermediate between two kinds of levels corresponding to storage data of a data read current passing through the selected memory cell.

Abstract: An intra-area connection order determining unit determines at random orders of connection of scan path circuits in each area divided by an placement area dividing unit. An inter-area connection order determining unit determines orders of connection of the scan path circuits between the areas such that length of interconnection between the areas divided by the placement area dividing unit becomes short. Accordingly, length of interconnection between the scan paths can be locally made short, reducing congestion of interconnections and generation of hold time errors.

Abstract: A main control circuit generates a plurality of main control signals of different phases to local control circuits. The local control circuits produce row-related control signals greater in number than the main control signals in accordance with these main control signals. A semiconductor memory device can be easily adapted to change in bank structure, and can perform a fast and stable operation with a low current consumption.

Abstract: An internal potential generation circuit of an SDRAM includes a standby VDDS generation circuit which has a relatively low current driving force and which generates an internal power supply potential, and an active VDDS generation circuit which has a relatively high current driving force, which is activated during a period after an external power supply potential is applied until a negative potential reaches a threshold potential, and in an activation period, and which generates the internal power supply potential. Therefore, it is possible to raise the internal power supply potential stably without increasing standby current when the power supply is turned on.
