One inventive aspect relates to a method for fabricating a high-k dielectric layer. The method comprises depositing onto a substrate a layer of a high-k dielectric material having a first thickness. The high-k dielectric material has a bulk density value and the first thickness is so that the high-k dielectric layer has a density of at least the bulk density value of the high-k dielectric material minus about 10%. The method further comprises thinning the high-k dielectric layer to a second thickness. Another inventive aspect relates to a semiconductor device comprising a high-k dielectric layer as fabricated by the method.

A mobile unit moves on a reference plane. The mobile unit has an object detection apparatus for detecting an object on the reference plane. The object detection apparatus includes a camera, a mirror, and a computer. The mirror cuts an image received by the camera such that the camera receives an image that is divided into a reference plane image and an object image. The reference plane image contains the reference plane. The object image contains the object and does not contain the reference plane. Therefore, the distance measuring apparatus can easily separate the region including the object and the region including no object, and accurately detect the distance to the object.

The television tuner 15a has a reference frequency for each channel number of television radio wave, and can be tuned to a television radio wave of a channel number on the basis of a reference frequency of the channel number, when setting the channel number. The television tuner 15a includes a booster 31 for boosting the television radio wave to be fed to an RF amplifier, inhibiter 29 for inhibiting the operation of the booster 31 by an external operation, and a memory 30 for memorizing an operation state of the inhibiter 29 corresponding to the channel number when setting the tuning frequency as the frequency of the channel number. When the channel number is selected, the inhibiter 29 is placed in the operation state memorized by the memory 30 corresponding to the channel number.

In a conventional construction to obtain a reference signal for a tuner and a subcarrier for color difference signal demodulation by only one quartz oscillator, the reference signal is unstable due to a PLL operation for oscillation of the subcarrier, which causes tuning error or tuning shift. To realize stable tuning operation, in an oscillation signal processing apparatus having a construction to use one quartz oscillator to obtain a reference signal for a tuner and a subcarrier to demodulate a color difference signal, a PLL operation is performed with the quartz oscillator and a color burst signal when the tuning operation is not performed, while a phase comparison operation is stopped and oscillation is fixed to 3.58 MHz when the tuning operation is performed.

A multi-system power supply circuit for providing power supplies different in system, has signal generating circuits which correspond to the power supplies different in system, and generates repetitive frequency signals corresponding to the number of power supply systems, or indicating voltage generating circuits which correspond to the power supplies different in system, and generates voltages corresponding to the number of power supply systems. When any one of the power supplies becomes abnormal, the repetitive signal supplied to the detection indicating circuit from the repetitive frequency signal generating circuit corresponding to that power supply is turned on and off, or the indicating voltage generating circuit applies the indicating voltage to the detection indicating circuit, so that it can be detected with ease which of the power supply systems is abnormal. Also in the case where the supply circuit of a plurality of power supply systems become abnormal, the repetitive frequencies which are indicated with a predetermined time interval, or the magnitudes of the voltages which are indicated are utilized to detect which systems are abnormal. Hence, the power supply circuit can be repaired or inspected with high efficiency.

A CRT driving circuit includes a cathode control circuit for controlling a cathode voltage of a CRT on the basis of a video signal created by a video circuit, a power supply circuit for creating a power supply voltage for each of the cathode control circuit and the video circuit, a switch circuit provided between the power supply circuit and the cathode control circuit, and a monitor control circuit for on/off controlling the switch circuit and the power supply circuit on the basis of a power-on/off externally inputted signal. In response to the power-on/off signal, when the monitor control circuit switches the switch circuit and the power supply circuit into an off-state, it turns off the power supply circuit later than the switch circuit. Even after a power-switch is turned off, the video signal is supplied to the cathode control circuit so that the cathode control circuit continues its on-state. Thus, the charges left in the CRT while the power-switch is turned off are discharged through the cathode control circuit in the on-state.

A heater abnormality detecting circuit includes a heater winding. A fly back pulse extracted by the heater winding is supplied to a heater through a heater resistor, and voltage-divided and supplied to a micro-computer. The micro-computer determines a normality or abnormality on the heater by determining whether or not it is inputted with the voltage-divided fly back pulse in a predetermined time period.
