Title: Acceleration increment correction factor learning device for internal combustion engine
Inventor: MIWA HIROMICHI
IPC: F02D41/14
Filed: 1989-12-26
Abstract: PURPOSE:To enhance operability and exhaust characteristic by setting the initial value factor of an acceleration increment correction factor to the optimum value by learning, and also by carrying out the learning of a reduction rate factor for further enhancing the convergence of learning. CONSTITUTION:Excess and deficiency is recognized by fuel excess/deficiency trend recognizing means (k) on the basis of the difference between a target fuel quantity and an estimated fuel quantity, and respective mean values in a prescribed period of time are obtained by a calculating means (l). When the sum total of both the total of the fuel excess in a prescribed period of time and the total of the fuel deficiency is greater than a prescribed value, a renewing means (m) learns the initial value factor of an acceleration increment correction factor in a storing means (e) so that the grand sum of the above sum total and the total of differences between the acceleration increment fuel quantity and the target fuel quantity becomes equal to the total of the differences between the acceleration increment fuel quantity and the target fuel quantity. When the total of the differences is less than a prescribed value, the initial value factor is corrected in accordance with the means excess and the means deficiency, and further by using this, the reduction rate of the acceleration increment correction factor is also learned. Thus, operability and exhaust characteristic can be enhanced.

Title: Method for preventing decomposition of bottom mud accumulated on water bottom and preventive for decomposition of bottom mud
Inventor: OKABAYASHI IKUO
IPC: C02F11/00
Filed: 1992-11-20
Abstract: PURPOSE:To provide a method for extremely easily controlling anaerobic fermentation of bottom mud accumulated on the water bottom at a low cost and preventing generation of decomposition odor. CONSTITUTION:The crushed dry material of dead leaves containing tannin is added into bottom mud accumulated on the water bottom. Tannin contained in the crushed dry material of dead leaves obstructs the growth of anaerobic fermentation bacteria. Since anaerobic fermentation is controlled, generation of decomposition odor from bottom mud is effectively prevented. There is a fear that water is colored by the crushed dry material of dead leaves containing tannin. However bottom mud adsorbs colored substance and therefore coloring is prevented. The crushed dry material of dead leaves containing tannin may be buried intactly or as moldings into bottom mud accumulated on the water bottom. Further the mixture of the crushed dry material of dead leaves containing tannin, inorganic powder and water may be buried as the moldings into bottom mud accumulated on the water bottom.

Title: Method for registering word accent
Inventor: SUZUKI TAKAHIRO
IPC: G10L13/02
Filed: 1987-12-28
Abstract: PURPOSE:To surely and easily execute a word registering operation by generating the composite tone output of a word by switching successively plural accent type information corresponding to a word and setting the accent type information which is brought to key designation to a registered accent type. CONSTITUTION:At the time of registering a word accent, the composite voice output of an accent type is generated together with the composite voice output of a word which has switched successively the accent type. Subsequently, the accent type is designated from the voice output of the accent type corresponding to a composite voice which becomes a correct accent. Accordingly, it is suffice that an operator only designates its listening contents themselves by a key input without knowing thoroughly the classification of the accent type, and also, it becomes unnecessary to execute separately the key input of various kinds of accent types. In such a way, the accent can be registered surely and easily.

Title: Method of removing basic material
Inventor: HAABUEI JIEI GURATSUBUSU
IPC: C07D401/04
Filed: 1987-12-28
Abstract: A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco without materially affecting the content of the other components of the tobacco. Tobacco is traversed with a solvent in the supercritical state or in the liquid state wherein nicotine and the other components dissolve in the solvent. The solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine. The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine. In addition, the tobacco may be pretreated with a chemical base which does not substantially react withe the tobacco components under ambient conditions but rather is activated under the conditions of the extraction process. Pretreatment of the tobacco with a chemical base neutralizes nicotine salts and permits the extraction process to be carried out under milder conditions.
