    • Independent power supply systems are provided for a peripheral circuit other than a column decoder, an array-relevant circuit, and a column decoder respectively, so that a peripheral power supply voltage, an array power supply voltage, and a column decoder power supply voltage generated independently of each other are supplied to the peripheral circuit, the array-relevant circuit, and the column decoder as an operating power supply voltage, respectively. Preferably, the column decoder power supply voltage during normal operation is set as an intermediate voltage between the peripheral power supply voltage and the array power supply voltage. Thus, an array configuration suitable for driving a transistor with a low voltage in order to achieve lower power consumption can be obtained.

    • A servo-parameter adjusting apparatus includes an acquiring unit that acquires an adjustment result measured by a servo control apparatus concerning position adjustment for a control target performed according to the servo parameters set in the servo control apparatus; a display control unit that simultaneously displays, on a display screen, a waveform corresponding to the acquired adjustment result, waveform values that are attributes concerning a part of the waveform, and servo parameters corresponding to the waveform; and a waveform-value changing unit that changes the displayed waveform values. When a waveform value is changed, the display control unit displays the changed waveform value on the display screen and displays, on the display screen, a waveform corresponding to the changed waveform value and a servo parameter corresponding to the changed waveform value.

    • The present invention is directed to provide a semiconductor device having a dual-port memory circuit in which influence of placement of replica cells exerted on enlargement of chip area is reduced. A memory cell array of a dual-port memory circuit has: a first replica cell array used to respond to an instruction of reading operation from one of dual ports; and a second replica cell array used to respond to an instruction of reading operation from the other dual port. Each of the replica cell arrays has: replica bit lines obtained by mutually short-circuiting parallel lines having a length obtained by cutting, in half, an inversion bit line and a non-inversion bit line of complementary bit lines to which data input/output terminals of a memory cell are coupled; and replica cells coupled to the replica bit lines and having transistor placement equivalent to that of the memory cells.

    • A channel-switching valve into which a high-pressure liquid and a low-pressure liquid flow is provided. The channel-switching valve includes a stator and a rotor which has a surface in contact with one surface of the stator and rotates while sliding on the contact surface. The stator has a plurality of liquid flow ports open to the contact surface, and the rotor has a plurality of channel grooves for connecting the liquid flow ports. One of the channel grooves is a straight groove passing through the rotational center of the rotor, and the other channel grooves are line-symmetrically arranged with respect to the straight channel groove. Alternatively, among the channel grooves, the channel grooves into which the high-pressure liquid flows are configured to be located on both sides of the rotational center of the rotor. Thus, a local load acting on the rotor during a high-pressure liquid-feeding process is reduced.

As a result, a local load acting on the rotor during a high-pressure liquid-feeding process is reduced, so that the contact surface is prevented from being scraped off by the edge of the opening of a port during the rotation of the rotor.
