Title: Acceleration slip controller
Inventor: IGATA HIROSHI
IPC: F02D41/04
Filed: 1990-11-20
Abstract: PURPOSE:To reliably obtain a drive torque control with no influence thereupon of, for example, external disturbances while enabling the control corresponding to a change in the road-surface conditions, by deciding the degree of reliability on the calculated road-surface friction coefficient to determine whether or not this coefficient can be used for drive torque control. CONSTITUTION:A TRC unit 50 calculates a road-surface friction coefficient from a detected vehicle-body acceleration to thereby control the drive torques of drive wheels 3a, 3b in accordance with amounts of slip and road-surface friction coefficients of these drive wheels 3a, 3b. When the calculated friction coefficient value has changed from a friction coefficient value used for the present drive torque control, the changed friction-coefficient values are compared with the amounts of slip of the drive wheels 3a, 3b to decide whether or not the calculated friction coefficient value can be used for drive torque control. This enables a reliable control of the drive torque without being influenced by external disturbances for example while enabling the control corresponding to a change in the road-surface conditions.

IPC: H04N7/18
Filed: 1991-11-28
Abstract: PURPOSE:To significantly improve reliability by detecting hazardous state for a car using the image data of a specified area taken by a color camera. CONSTITUTION:When a system is turned on, a color camera 1 is activated and then a specified area on a memory 7 is initialized. Then, a system microcomputer 3 reads current car speed out of a car speed sensor 5. If the speed is zero, a speed is re-read and the system is blocked from getting into full operation until the car starts to move. In this system, only the image data of a specified area directly related with car safety among image signals obtained with the color camara 1 is taken into the system microcomputer 3 for detecting hazard on and after that. However, the length in the travelling direction of a specified area must be a proper distance between cars, proportional to car speed. Thus, hazard is reported to a driver with high reliability without affected by proceeding car's state and external conditions.

Title: Voice encoding system
Inventor: ASAKAWA YOSHIAKI
IPC: G10L19/08
Filed: 1987-12-14
Abstract: PURPOSE: To prevent deterioration in sound quality due to disorder of periodicity of each frame as to a pulse train by providing a sound source pulse generating means which generates sound source pulses in the case of a voiceless sound frame. CONSTITUTION: At the time of encoding, a digitized voice signal is stored in a buffer memory 1 by one frame and converted by a linear predicting circuit 3 into a parameter 4 representing a spectrum envelope. A voiced/voiceless sound decision circuit 9 outputs a decision result 10a showing whether the frame is a voiced sound frame or a voiceless sound frame and a signal 10b indicating switching from the voiceless sound frame to the voiced sound frame. A sound source generation part 11 generates sound source pulses according to the voiced/ voiceless sound decision result 10a and switching signal 10b and outputs its information 12. Consequently, the sound source pulse train is generated without disordering the periodicity that the original voice has, so the sound quality is prevented from deteriorating owing to the disorder of periodicity and the quality of an encoded voice is improved.

Title: Color display
Inventor: POORU II GUURITSUKU
IPC: G02F1/1347
Filed: 1990-11-22
Abstract: PURPOSE: To produce a brighter display device by operating plural birefringence cells in combination with color polarizers to realize one color display system and compensating and correcting the birefringence color in this case. CONSTITUTION: Light made incident on a first panel 12 is polarized by a first polarizer 20. The magenta polarizer 20 allows white light parallel with its axis to pass through and allows blue and red light orthogonal to the axis to pass through. Since light passes a display partial assembly 10 with these blue and red light added, it contributes to brightness of the whole of display. When a polarizer 28 adjacent to a panel 18 is colored in cyan, blue and green light which are normally absorbed there are leaked and emitted from the display partial assembly 10, and therefore, brightness is improved. Thus, two color polarizers are used to considerably improve the brightness of display though normal achromatic polarizers are used as polarizers 22, 24, and 26 placed in the middle of a liquid crystal panel.
