An apparatus for reading out a differential capacity with a first and second partial capacity includes a first oscillator having a first frequency-determining element connectable to the first partial capacity and a second oscillator having a second frequency-determining element connectable to the second partial capacity; a switching means to switch the first frequency-determining element into a first state or to switch it into a second state, and to switch the second frequency-determining element into a third state or to switch it into a fourth state; read apparatus having a first detection means connected to the first oscillator; and an evaluation means which carries out a quotient formation to obtain a value indicating a quotient of the first and the second partial capacity.

There is provided a semiconductor storage device which is capable of further reducing a size of a memory cell, and increasing a storage capacity. Plural memory cells each including a transistor formed on a semiconductor substrate, and a variable resistive device having a resistance value changed by voltage supply and connected between source and drain terminals of the transistor are arranged longitudinally and in an array to configure a three-dimensional memory cell array. A memory cell structure has a double channel structure in which an inside of a switching transistor is filled with a variable resistance element, particularly, a phase change material. The switching transistor is turned off by application of a voltage to increase a channel resistance so that a current flows in the internal phase change material to operate the memory.

A refrigerator having a room (3) the temperature in which can be switched, by cooling by a cooling device (17) and by heating by a heater (15), between the low temperature side where an object is stored cooled and the high temperature side where the temperature is maintained in the range of 50 DEG C - 80 DEG C in which food to be heated is kept warm.

A series resonant converter circuit that reduces power loss is provided that includes an inverter circuit having at least a pair of first and second switching elements that is connected between DC input terminals, a transformer connected to this inverter circuit, a resonant inductance means that are connected in series to a primary winding wire or a secondary winding wire of the transformer, a primary-side resonant capacitor that is connected in series to the resonant inductance means through the first or second switching element, first and second secondary-side resonant capacitors that are connected to each other in series between the DC input terminals, first and second unidirectional elements that are connected to each other in series between the DC output terminals, and a resonant inductance means that cooperates with resonant capacitance from the primary-side resonant capacitor and the first and second secondary-side resonant capacitors to resonate in series.

A lower movable electrode 35, having line sections 35a, 35a on both ends and a capacitor section 35b in the center, and an upper movable electrode 37, having line sections 37a, 37a on both ends and a capacitor section 37b in the center, are placed so that the capacitor sections 35b, 37b face each other, and drive electrodes of lower-movable-electrode actuators 27a, 27b, 27c, 27d driving the lower movable electrode 35 and upper-movable-electrode actuators 29a, 29b, 29c, 29d driving the upper movable electrode 37 are electrically separated from the lower movable electrode 35 and upper movable electrode 37. These actuators 27a to 27d and / or 29a to 29d move the lower movable electrode 35 and / or upper movable electrode 37 to adjust the distance between both capacitor sections 35b, 37b, and control the electrostatic capacity.

An optimal pump flow for both dual tilt operations and single tilt operations is obtained at low cost without increasing the complexity of the device constitution. Where there is a wish to implement a dual tilt operation, a switch is selectively operated and, in accordance with this selection result, the differential pressure set value decreases and a comparatively small flow is supplied from the hydraulic pump to the left and right tilt cylinders. Accordingly, the extension / retraction speed of the left and right tilt cylinders decreases. Where there is a wish to implement a single tilt operation, a switch is selectively operated and, in accordance with this selection result, the differential pressure set value increases and a comparatively large flow is supplied from the hydraulic pump to the left cylinder. Accordingly, the extension / retraction speed of the left tilt cylinder increases. In this way, the tilt operating speed of the blade in dual tilt operations is made to be the same as the tilt operating speed of the blade in single tilt operations. By virtue of this, when a changeover is implemented from a dual tilt operation to a single tilt operation (or when the reverse changeover thereto is implemented), the operating speed of the blade 3 is unaltered and the discomfort associated with the alteration of the operating speed when this changeover is implemented can be alleviated. Accordingly, the operability throughout the working of the bulldozer is markedly improved.
