IPC: G01C19/72
Filed: 1992-04-07
Abstract: PURPOSE:To fix a smaller phase modulation factor by modulating the amplitude of a phase modulation with the frequency lower than the phase modulation frequency. CONSTITUTION:An oscillator 12 (OMEGAa) slightly amplitude-modulating the amplitude of a phase modulation is provided in addition to an oscillator 11 generating the angular frequency OMEGA for the phase modulation, and a product operation 14 on both oscillators 11, 12 is performed. The piezoelectric element control voltage (b0+asinOMEGAa)sin OMEGAt is applied to a phase modulator 7 via the PZT operating point control 13. The amplitude (b) of the phase modulation is extended as b=b0+asinOMEGAat. The amplitude (a) of the amplitude modulation is much smaller than (b), and a <b0. The frequency OMEGAa of the amplitude modulation is much smaller than the frequency Q of the phase modulation, and OMEGAa<<OMEGA. The output of a light receiving element 8 is synchronously detected, and the DC constituent, fundamental wave constituent, and harmonic wave constituents are obtained. The DC constituent and the second harmonic constituent are synchronously detected 16 with the frequency OMEGA of the amplitude modulation, and the phase modulation quantity epsilon(b) is determined to make these values zero, i.e., the driving voltage of a piezoelectric element is controlled, and epsilon can be fixed to a value as epsilon<5.2.

IPC: B60S1/08
Filed: 1988-05-13
Abstract: PURPOSE:To aim at accurate operation by performing a level comparison of value after the alternating amplification when performing wiper drive upon arithmetically processing a frequency signal at a water drop detecting means by an optical sensor together with the detected frequency signal, and keeping off any misdetection due to a sudden change in outside light. CONSTITUTION:Light of the specified frequency out of a light emitting element 12 is made incident into a light transmittable member, and the change is detected by a light receiving element 13, performing waterdrop detection, and those of wave filtration, rectification, differentiation or the like are processed, thus wiper drive is automatically carried out. A part of a detecting frequency signal is fed to both first and second inhibiting output parts 4, 5, and a level comparison takes place after alternating amplification at the first inhibiting output part 4, then this level comparison takes place as it is at the second inhibiting output part 5. A drop in detection sensitivity of a level comparator 36 of a driving signal generating part 3 is performed by each output of these inhibiting output parts 4, 5. At the time of a sudden change in outside light, any misdetection attendant upon a luminosity change under direct sunlight is kept back, whereby the misdetection of an automatic driver such as a windshield wiper or the like is effectively prevented from occurring.

IPC: G11B15/68
Filed: 1992-05-08
Abstract: PURPOSE:To automatically exchange a disk-like recording medium by inhibiting the count of pulses from a position sensor until the specific number of pulses from a sensor for the amount of action is obtained after a pulse signal from the position sensor is detected. CONSTITUTION:A pulling-out/putting-in mechanism 3 pulls out a disired recording medium 1 (1-1 to 1-n) from a magazine 2. A pulse signal HP indicating a storing position corresponding to the relative position of the mechanism 3 and the magazine 2 is outputted from a sensor S7. A motor 25 moves the magazine 2 and the mechanism 2 relatively by the rotation of an output shaft. A pulse signal POT is outputted from a sensor for the amount of action S8 corresponding to the rotation of the output shaft, and the amount of relative movement between the mechanism 3 and the magazine 2 is given with higher resolution than the position sensor S7. A control means 26 produces a signal DE controlling a player 5 from the signals HP and POT outputted from the sensors S7 and S8. The control means 26 counts the number of the HP and detects the relative position of the mechanism 3 and the magazine 2, then inhibits the count of the HP until the specific number of the BOT is obtained after the detection of the UP. By such a constitution, the medium is automatically exchanged.

Abstract: PURPOSE: To prevent arrival of light by adding a substance for absorbing or reflecting the external light to a soft resin being provided on a semiconductor pressure sensor. CONSTITUTION: A semiconductor pressure sensor chip 1 is fixed onto a base 2a and the sensor is connected electrically with a stem 3 through a metal wire 4.

Filed: 1993-05-19
Abstract: PURPOSE: To provide a skin preliminaly treatment/monitor dual purpose electrode which is applied to a patient's kin before receiving a bioelectric potential. CONSTITUTION: This skin preliminaly treatment/monitor dual purpose electrode 12 reduces an artifact caused by movement of a skin to appear on a bioelectric potential by pricking a patient's skin before obtaining the bioelectric potential. By pricking the skin, a propensity of the skin which frequently generates the artifact caused by a skin impedance and its movement is reduced.
