Patent number: 5731842Abstract: In a TV signal encoder device comprising, for encoding a digital TV signal into an encoder device output signal, both having a predetermined dynamic range, an amplitude limiter, a predictive encoder unit for predictive encoding with quantization an amplitude limited signal of a limited dynamic range into a quantized signal having together with quantization noise the predetermined dynamic range, and a code converter for code converting the quantized signal into the device output signal, a forward offset circuit adaptively gives a forward shift to the TV signal so as to avoid undesirable clipping of tip ends of synchronizing signals in the amplitude limited signal. The forward shift and a lower and a higher range reduction of the predetermined dynamic range into the limited dynamic range are preferably equal to a maximum quantization noise level. Instead of the offset circuit, use of an encoder dynamic range defining circuit is more preferred.Type: GrantFiled: November 20, 1995Date of Patent: March 24, 1998Assignee: NEC CorporationInventor: Norio Suzuki

Patent number: 5715796Abstract: There is provided an air-fuel ratio control system for an internal combustion engine installed on an automotive vehicle. The control system controls the air-fuel ratio of a mixture supplied to the engine to a value leaner than a stoichiometric air-fuel ratio immediately after the start of the engine. Operating conditions of the engine and/or operating conditions of the automotive vehicle are detected. Starting of the vehicle is predicted based on the detected operating conditions of the engine and/or the detected operating conditions of the automotive vehicle. The air-fuel ratio of the mixture supplied to the engine is changed to a richer value than the leaner value when the starting of the vehicle is predicted.Type: GrantFiled: February 20, 1996Date of Patent: February 10, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Norio Suzuki, Koichi Fujimori, Yusuke Hasegawa, Hiroki Munakata, Shusuke Akazaki, Masuhiro Yoshizaki

Patent number: 5694174Abstract: In a television signal transmission system including a transmitter and a receiver, a reference signal has a phase angle between 0.degree. and 360.degree. within a single cycle. The phase angle of the reference signal is successively produced by a phase angle generator and transmitted from the transmitter and is reproduced by the receiver to be compared with a received phase angle. The phase angle is modified by a compensation phase angle obtained from a phase difference in the transmitter and the receiver. The reference signal may be either a color subcarrier signal or a sequence of sampling clocks.Type: GrantFiled: October 23, 1995Date of Patent: December 2, 1997Assignee: NEC CorporationInventor: Norio Suzuki
