Title: Oscillatory wave motor
Inventor: SEGAWA SATORU
IPC: H02N2/00
Filed: 1988-09-07
Abstract: PURPOSE:To improve the controllability of a motor reduced in its cost of manufacture by providing a pressure detecting part, which detects a pressure with a stator, in an annular rotor and detecting a phase difference between a signal, output from the pressure detecting part, and a signal supplied to the annular resonator and obtained from a motor driving circuit. CONSTITUTION:A pressure detector 1-120 built in a rotor is constituted of a piezoelectric element and a piezoelectric material of PVDF or the like, and a pressure detecting part 1-125 is provided in one part of the detector. A signal 1-a from this detector is converted by a waveform processing circuit 1-4 into a rectangular pulse signal 1-b synchronized with the signal 1-a. And the signal 1-b is fed to an incremental rotary angle signal generator circuit 1-3, together with a signal 1-c obtained from a motor driving circuit 1-2. In the incremental rotary angle signal generator circuit 1-3, a phase difference between two vibrative signals of the signal 1-c and the signal 1-b relates to a rotary angle of the rotor. When this phase difference exceeds a specified quantity, an incremental pulse is output.

Title: Driving method for active matrix type display device
Inventor: OKI KENICHI
IPC: G09G3/20
Filed: 1988-09-10
Abstract: PURPOSE:To lower a voltage value of negative polarity applied to a gate by applying an address voltage to a scan bus line, and thereafter, applying an intermediate voltage between the address voltage and a non-address voltage. CONSTITUTION:When an address voltage Vgon is applied to a scan bus line 2, a TFT 3 whose gate G is connected to its scan bus line 2 becomes an ON state. Subsequently, after its address voltage Vgon is applied, a voltage Vm which is selected to a relation of Vgon > Vm > Vgoff (non-address voltage) is applied. When this voltage Vm is applied, the address voltage Vgon is applied to the scan bus line 2 of a rear position in the scanning direction, therefore, a gate - drain voltage of the TFT 3 in which the voltage Vm is applied to the gate G becomes Vm - Vgon. In this case, since there is a relation of Vm > Vgoff, the gate - drain voltage becomes smaller than before. In such a way, a negative polarity voltage applied to the gate G of the TFT 3 is reduced, and a shift in the negative direction of a threshold voltage can be suppressed.

Title: Magnetic recording and reproducing device
Inventor: TAKASE OSAMU
IPC: H04N9/83
Filed: 1988-09-12
Abstract: PURPOSE:To eliminate a crosstalk component from an adjacent track by recording a chroma signal so as to make a phase relation of the chroma signal at each recording track to a prescribed value and using a frame correlation comb line filter or field correlation comb line filter for the processing at the reproduction side. CONSTITUTION:A circuit comprising an input terminal 20, a 1/2 frequency divider circuit 21, an AND gate 22 and a switch circuit 19 inverts a phase of a recorded chroma signal only at a prescribed field. Thus, one field among four fields of a recorded chroma signal is subjected to phase inversion. When a signal 1b is subtracted from a signal 1a, since the phases are opposite to each other, an output signal being nearly twice the signal 1a is obtained. In this case, the adjacent crosstalk components are subtracted simultaneously, since the signal 2a has a strong correlation to the signal 2b and the signal 3a has a strong correlation to the signal 3b respectively and the phases are in-phase to each other, the crosstalk components are almost cancelled with each other.

Title: Flicker reduction circuit
Inventor: HIRAYANAGI KOJI
IPC: G09G1/16
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a flicker reduction circuit where deterioration in resolution is little. SOLUTION: In this flicker reduction circuit, a YUV converter 2 converts the output image out from an image output device 1 into a YUV output image, and a vertical direction low-pass filter 22 eliminates a vertical direction high frequency component of luminance. Since a remarkable change in the luminance in vertical directions close to each other is suppressed, flicker on a television receiver adopting the interlaced scanning is reduced. Since the deterioration in resolution of the image is caused by cutting off a high frequency component, a filter parameter 21 controls an upper limit of a frequency eliminated by the vertical direction low-pass filter 22 to suppress deterioration in resolution.  Since the degree of the flicker is changed with the luminance, the upper limit of the frequency eliminated by the vertical direction low-pass filter 22 is set based on the luminance (Y signal) of the YUV output image and when the luminance is not so high, the deterioration in resolution is suppressed by increasing the cut-off frequency.

Title: Vehicle weight calculation system
Inventor: HORIGUCHI MASANOBU
IPC: G01G19/12
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To calculate the weight of vehicle without requiring any special sensor. SOLUTION: Driving force F of a vehicle is calculated (S1) followed by calculation of acceleration (a) (S2). An acceleration resistance Ra=a×WBASE, i.e., the product of acceleration (a) and the basic weight of vehicle WBASE, and the sum of air resistance Rr1 and rolling resistance determined by the vehicle speed VSP are then subtracted from the driving force F thus determining a running resistance Rs=F-Ra-Rr1 corresponding to the grade resistance (S3-S5). Subsequently, time variation of acceleration Δa=a-a' is calculated (S6) followed by calculation of time variation of running resistance corresponding to grade resistance ΔRS=Rs-Rs' (S7). The basic weight of vehicle WBASE is then added with an amount of time variation of running resistance ΔRs/time variation of acceleration Δa to calculate a vehicle weight WREAL=WBASE+(ΔRs/Δa)×K (S9) which is finally averaged (S10).
