  • METHOD OF MANUFACTURING A PHOTOMASK
    Publication number: 20120034552
    Abstract: A thin film composed of a material containing a metal and silicon is formed on a transparent substrate, and a thin film pattern is formed by patterning the thin film. Then, the main surface and the side walls of the thin film pattern are previously modified so as to prevent the transfer characteristics of the thin film pattern from changing more than predetermined even in the case where exposure light with a wavelength of 200 nm or less is cumulatively applied onto the thin film pattern which has been formed. The main surface and the side walls are modified by, for instance, performing heat treatment to the main surface and the side walls at 450-900° C. in the atmosphere containing oxygen.

  • PARTICULATE MATTER DETECTION SENSOR AND PARTICULATE MATTER DETECTION SENSOR UNIT
    Publication number: 20110283773
    Abstract: In a PM detection sensor with a sensor element having a pair of detection electrodes formed on a substrate, quantity of PM accumulated in the detection electrode is calculated on the basis of a resistance change between the detection electrodes. A series circuit composed of a temperature detection resistance and a capacitor connected in series is formed on a conductive path in the sensor element. A microcomputer in an ECU instructs a power source to supply a DC voltage to the resistance and the capacitor to make a first state in which no current flows in the resistance when a quantity of PM accumulated in the sensor element is detected. The microcomputer instructs the power source to supply an AC voltage to the resistance and the capacitor to make a second state in which a current flows in the resistance when a temperature of the sensor element is detected.

  • DETECTION DEVICE FOR DETECTING IMPEDANCE OF SENSOR ELEMENT IN GAS SENSOR AND SENSOR UNIT EQUIPPED WITH DETECTION DEVICE
    Publication number: 20110279129
    Abstract: In a sensor control circuit, an impedance signal output unit has a HPF, a P/H circuit, a LPF, etc., and detects an element impedance of a sensor element on the basis of an impedance response signal which is alternately changed in response to an alternating current signal supplied to the sensor element. The P/H circuit has an input comparator which inputs an impedance detection voltage Vz after the HPF, a rectifying element connected to the P/H circuit, and a hold capacitor which is charged by the output of the input comparator. The input comparator has a constant current circuit and a transistor. The constant current circuit limits an updating value of a hold voltage value Vph of the hold capacitor every alternating current period. The sensor control device detects the element impedance of the sensor element with high accuracy while preventing influence of noise.

  • Gas sensor control apparatus designed to ensure accuracy of measurement in gas sensor
    Patent number: 8052863
    Abstract: The gas sensor control apparatus develops a first voltage based on a first reference voltage at a negative terminal of a gas sensor device through a resistor and a second voltage based on a second reference voltage at a positive terminal of the gas sensor device. A controller samples through the resistor a sensor current, as created upon the development of the first and second voltage for measuring the concentration of gas. When the impedance of the gas sensor device is measured, the controller alternates the first voltage across the first reference voltage. The value (i.e., a zero-point) of the voltage applied to the gas sensor device when the sensor current is zero (i.e., 0 mA) depends upon the first and second reference voltages. The zero-point is corrected by regulating the second reference voltage to match an applying voltage characteristic to the gas sensor device correctly.

  • Gas concentration measuring apparatus designed to enhance measurement accuracy in desired range
    Patent number: 7981265
    Abstract: A gas concentration measuring apparatus for use in air-fuel ratio control of automotive engines is designed to determine the concentration of oxygen within a wide and a narrow range using a sensor current flowing through a sensor element. The apparatus includes an amplifier circuit equipped with an operational amplifier and a plurality of amplifying resistors and a switch. The switch is responsive to a request signal to switch a relation in electrical connection between an operational amplifier and the amplifying resistors to distribute the amplifying resistors into an input resistor and a feedback resistor for the operational amplifier to change an amplification factor of the amplifier circuit. This results in a change in resolution of measurement of the concentration of oxygen, thereby ensuring enhanced accuracy in determining the concentration of oxygen in a selected one of the narrow and wide ranges.

  • TV ACTING AS POTS PHONE SWITCH
    Publication number: 20110051716
    Abstract: A TV receives IP calls and POTS calls. When a POTS call is received the TV passively passes the call to a non-IP phone, and when an IP call is received the TV processes the IP packets as appropriate for the non-IP phone and passes the call to the phone. The non-IP phone can also signal using a special code a desired to place an IP call, with the signals from the phone being rendered into IP packets by the TV. In this way, a non-IP phone may be used to place and receive both POTS calls and IP-based calls.
