An optical switch includes a mirror to reflect an input light; a controller to generate a control signal representing a target rotation angle of the mirror; a generator to generate a low-frequency signal; an adder to superimpose the low-frequency signal on the control signal; a driver to drive the mirror with a drive voltage corresponding to the control signal on which the low-frequency signal is superimposed; a detector to detect a frequency component or a harmonic component of the low-frequency signal included in an output light reflected by the mirror; and a correction unit to correct the control signal based on the detection result by the detector. The generator determines an amplitude of the low-frequency signal according to the target rotation angle.

A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.

In order to allow bit-interleaved-parity calculation to be easily performed while maintaining compatibility with an existing system during transmission of data having mixed bit rates, header information of a first bit rate is added to data of the first bit rate and data of a second bit rate, time-division multiplexing is performed on the header-information-added data signals to generate a data string and a frame header is added thereto to generate a frame signal, parities of the frame signal that is sequentially generated are determined, parity bits for parity checking for the data signals of the first bit rate and the data signals of the second bit rate are inserted into the frame signal, based on a result of the parity calculation.

A memory cell of the type employing a pair of cross-coupled CMOS inverters of a SRAM is disclosed in which the load MISFETs are stacked above the semiconductor substrate and over the drive MISFETs. Each load MISFET of a memory cell consists of a source, drain and channel region formed of a semiconductor strip, such as a polycrystalline silicon film strip, and a gate electrode consisting of a different layer conductive film than that of the drive MISFETs. In a memory cell having such a stacked arrangement, the source region and gate electrode of each load MISFET thereof are patterned to have a widely overlapping relationship with each other to form a capacitor element thereacross such that an increase in the overall capacitance associated with each of the memory cell storage nodes is effected thereby decreasing occurrence of soft error. The overlapping relationship for effecting the large capacitor element across the source and gate of the respective load MISFETs is provided by an ion implanting scheme of a p-type impurity into the semiconductor strip. A separate mask for ion-implantation for the formation of the source region of the load MISFET is added followed by the addition of the gate electrode thereof in a manner so as to have a widely overlapping relationship with that of the source region.

In a defibrillator with an electrocardiographic monitor which monitors electrocardiographic signals induced at electrodes by means of a preamplifier and supplying the signals to an electrocardiographic signal processing circuit through high-pass filters, the dynamic range of a preamplifier is made wider in accordance with the amplitude of a polarization voltage which is developed when a defibrillator is operated. A high-pass filter is formed of a first high-pass filter which operates in a normal state and a second high-pass filter whose blocking frequency is higher than that of the first high-pass filter so that the polarization voltage is attenuated without erasing the electrocardiographic signals. The second high-pass filter is operated in synchronization with the operation of the defibrillator during a time period corresponding to the time period in which the polarization voltage is generated.

A semiconductor memory device having STC cells wherein the major portions of active regions consisting of channel-forming portions are inclined at an angle of 45 degrees with respect to word lines and bit lines that meet at right angles with each other, thereby enabling the storage capacity portions to be arranged very densely and a sufficiently large capacity to be maintained with very small cell areas. Since the storage capacity portions are formed even on the bit lines, the bit lines are shielded, so that the capacity decreases between the bit lines and, hence, the memory array noise decreases. It is also possible to design the charge storage capacity portion so that a part of thereof has a form of a wall substantially vertical to the substrate in order to increase the capacity.

A power converter comprising a current-type inverter is disclosed, in which an output of a converter unit is applied as an input to the inverter unit through a DC reactor, and AC power is supplied to a load from the inverter unit. A ripple component of the DC input of the inverter unit is detected, and the switching elements of the inverter unit are controlled by modulation rate if they are to be subjected to PWM control, thus completing a sinusoidal waveform of the output of the inverter unit. Specifically, since the input to the inverter unit is allowed to contain a ripple, the DC reactor is reduced in size. The output of the inverter unit is a sinusoidal AC power containing no high harmonics and therefore the load is free of effects of high harmonics.
