Title: Method of torque variation control in internal combustion engine
Inventor: MITSUYASU MASAKI
IPC: F02D41/34
Filed: 1982-08-12
Abstract: PURPOSE:To minimize shaking action of a car, by preventing excessive engine torque variation due to abrupt opening closing of a throttle valve at the time of acceleration or deceleration without worsening responsiveness for acceleration of an engine. CONSTITUTION:Required throttle control opening is obtained from difference between the present target throttle opening corresponding to accelerator opening outputted from an accelerator sensor 34 and the last throttle opening outputted from a throttle sensor 24. Torque variation is estimated based on the engine rotating speed obtained from the required throttle control opening, the last throttle opening, and the output of a crank angle sensor 38. When the estimated torque variation exceeds the limit value, a throttle control opening is obtained that is smaller than the limit throttle opening at which the torque variation is equal to the limit value. With this throttle control opening, a throttle valve 20 is controlled for a prescribed short period of time via an actuator 22 while fuel injection time is controlled by an electronic control circuit 44.

Title: Picture signal recorder and picture signal reproducing device
Inventor: OKU MASUO
IPC: H04N7/015
Filed: 1993-06-11
Abstract: PURPOSE:To record and reproduce efficiently a MUSE signal and an NTSC signal whose resolution differs from each other entirely. CONSTITUTION:When an NTSC signal is recorded, the NTSC signal is decoded by a decoder 2 and compressed by a picture compression circuit 3b and fed to an error correction coding circuit 5 and a modulation circuit 6. When a MUSE signal with high resolution is recorded, the MUS signal is subjected to interpolation and band limit processing by a MUSE signal decoder 1 and compressed by a picture compression circuit 3a and fed to the error correction coding circuit 5 and the modulation circuit 6 as a signal with nearly equal data rate to that of the NTSC signal. Since the MUSE signal and the NTSC signal whose resolution is entirely different from each other are made to be signals of nearly equal data rate, most of the recording processing circuit and the reproduction processing circuit is used in common for the MUSE signal and the NTSC signal and the recording band of the recording medium is effectively utilized.
