Title: Manufacture of tapered steel plate
Inventor: KAWABATA TOMOYA
IPC: B21B45/02
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of quality and acoustic anisotropy by cooling after executing heating and hot-rolling under specific temp. condition to a steel slab and further, water-cooling under plactically same temp. width together with thick edge side and thin edge side. SOLUTION: Preceding to the hot-rolling, the heating is first executed at Ac3 point or above because at this time, but in this case, if the heating temp. is <Ac3 point, the cast slab is not fully austenized, non-transformed part remains and the uniformization is not obtd. So, the temp. is increased to >=Ac3 . Then, the acoustic anisotropy can be reduced by executing the hot-rolling at >=750 deg.C finish temp. to promote recrystallization. Further, since the thin edge side is air-cooled quicker than the thick edge side in a tapered steel plate, the finish temp. at the thin edge side becoming the lowest temp. in the finish temp., is regulated. Therefore, the tapered steel plate having extremely little dispersion of the quality, is obtd. by eliminating the difference between both temps., in either case of the starting and the stopping temp. of the cooling.

Title: Ignition timing control device for internal combustion engine
Inventor: MIYASHITA KOTARO
IPC: F02P5/153
Filed: 1993-12-30
Abstract: PURPOSE:To prevent output loss by computing an upper limit value of octane estimation value on the basis of an operational state, determining a final estimation value according to an estimation value when the estimation value is smaller than an upper limit value and according to an upper limit value when it is larger and thus computing an ignition timing correction quantity and so determining a final ignition timing. CONSTITUTION:When knocking occurs an octane estimation value KRO is compared with an octane value estimation learning value KRREF. When thus an estimation value exceeds a learning value, a learning value is taken as an estimation value. Then, an estimation learning value and an upper limit value KRMBT by obtained MBT are compared. When a learning value is smaller than an upper limit value, an estimation value is compared with an estimation learning value. Then, when an estimation value is larger than a learning value, a learning value is taken as an estimation final value. When an estimation value is smaller than a learning value, an estimation value is taken as a final value. When a learning value is larger than an upper limit value, an estimation value is compared with an upper limit value. When it is thus larger, an upper limit value is taken as estimation final value. The treatment so far, becomes equivalent to the ignition timing exceeding MBT in angle advance direction, so that unnecessary engine output loss can be evaded.
