Inventor: WAITE TIMOTHY P
IPC: G01B7/06
Filed: 1990-07-27
Abstract: A coin validator (2) has a thickness sensor formed by two coils (10, 12) positioned one on each side of the coin path. The coil outputs are processed separately using a look-up table (20) to derive values which are linearly related to coin position across the width of the passage, using the same constant of proportionality for both sensors. Accordingly, by combining the processed outputs there is derived a value which is independent of coin position and which can be peak-detected to indicate thickness.

Inventor: MINAMI YOICHIRO
IPC: H04L27/14
Filed: 1992-04-08
Abstract: An FSK (Frequency Shift Keying) receiver capable of reducing the deterioration of sensitivity suppression ascribable to interference waves despite the use of an orthogonal detection type reception system. Mixers for generating baseband signals are followed by high pass filters, low pass filters, and an orthogonal detection modulator. The baseband signals from the mixers are each applied to respective one of the high pass filters while the output signals of the high pass filters are fed to the associated low pass filters. The demodulator processes the output signal of the low pass filters to produce a demodulated signal. The high pass filters attenuate the demodulated signals of interference waves.

Title: Method and apparatus for detecting a contaminated alcohol-gasoline fuel mixture
Inventor: AMENT FRANK
IPC: B60R16/023
Filed: 1992-08-20
Abstract: An method and apparatus are described for detecting dissolved contaminants in an alcohol-gasoline mixture used for fueling an internal combustion engine and then indicating that the fuel mixture is of substandard quality when the degree of contamination reaches an unacceptable level.  The resistivity of the fuel mixture, which varies as a function of the degree of contamination, is measured using a sensor positioned in the engine fuel supply line.  When the measured resistivity of the fuel decreases below a threshold amount, an indication of substandard fuel quality is provided.  The threshold amount may be a fixed constant, or its value may vary depending upon the proportion of alcohol to gasoline in the fuel mixture. The composition of the fuel mixture is determined by using a capacitive sensor to measuring the fuel dielectric constant.  A separate resistive sensor may be used for sensing fuel resistivity, or the same sensor used for sensing the fuel dielectric constant can be switched between resistive and capacitive measuring circuitry.

Title: Method of estimating vehicle velocity and method of and system for controlling brakes
Inventor: SUZUKI OSAMU
IPC: B60T8/174
Filed: 1992-10-07
Abstract: A method of and an apparatus for estimating a vehicle velocity, which are suitable for use in a vehicle.  Velocities of drive wheels and follower wheels of the vehicle are determined and the fastest one of the so-determined velocities is selected.  The velocity of the vehicle is estimated based on the fastest wheel velocity thus selected.  The above respective processes are repeatedly executed at given time intervals.  Thus, when the estimated vehicle velocity is faster than each of the velocities of the follower wheels and lower than the fastest wheel velocity, the estimated vehicle velocity determined immediately before the above estimating process is set as a desired estimated vehicle velocity. Accordingly, a high-accuracy estimated vehicle velocity corresponding to an actual vehicle velocity can be obtained, thereby making it possible to control brakes and driving forces with high accuracy using the estimated vehicle velocity.

Title: X-ray exposure apparatus and semiconductor-device manufacturing method
Inventor: EBINUMA RYUICHI
IPC: H01L21/027
Filed: 1992-10-28
Abstract: X-rays enter an airtight chamber through a beam duct, pass through a transmission window, and expose a wafer and mask disposed outside the airtight chamber. The wafer and mask are held by a wafer chuck and a mask holder, respectively.          The mask holder includes a pressure sensor, which detects variations in the atmospheric pressure. An output from the pressure sensor is converted into a change in the intensity of the x-rays by an arithmetic unit, and is transmitted to a control unit, which controls a driving unit of a shutter. By thus controlling the moving speed of the shutter in accordance with variations in the atmospheric pressure, it is possible to prevent variations in the amount of x-ray exposure of the wafer.
