Title: Reading head for magneto-optical disk
Inventor: FUKUSHIMA NOBUHIRO
IPC: G11B7/095
Filed: 1988-08-30
Abstract: PURPOSE:To enlarge the degree of margin to a setting error by arranging a Faraday rotator, whose rotational angle is enough large in comparison with the Kerr rotational angle of a recording medium, in an external resonator. CONSTITUTION:When the rotational angle of a Faraday rotator 6 is increased, relative beat frequency difference is enlarged. For example, when the rotational angle goes to 20 deg., such a condition is almost equal with a case that there is nor error in a setting angle. Namely, when the rotational angle of the Faraday rotator 6 is enough large, polarization on a magneto-optical disk 3 surface is close to circular polarization and there is no degradation in the change of a beat signal. Then, information to be recorded to the magneto-optical disk 3 can be enough detected. In such a manner, since the Faraday rotator 6, whose rotational angle is enough large in comparison with the Kerr rotational angle of the recording medium, is arranged in an external resonator 4, the polarization on the medium surface is close to the circular polarization. Thus, the degree of the margin can be enlarged to the setting error, etc.

Secondly, the crude solution is distilled to form an intermediate mixture 1-40wt.% in water content (pref. with a solidifying point of 65-70°C), which is, in turn, transported from the 1st production plant to 2nd production plant. Subsequently, the above mixture is fully distilled at the 2nd production plant to obtain an anhydrous toluylenediamine which is then phosgenated, thus obtaining the objective toluylene diisocyanate. It is recommended that the distillation of the crude solution is carried out at the atmospheric pressure and that of the intermediate mixture of the 2nd production plant by a vacuum distilling plant.

Filed: 1984-10-18
Abstract: PURPOSE:To keep off the overlean of an air-fuel ratio in the initial stage of acceleration as well as to improve accelerability ever so better, by discriminating that whether a ratio of each throttle valve opening this time and the last is more than the specified value or not and, when it is more than the specified value, performing a quantity of a asynchronous injection corresponding to the said ratio. CONSTITUTION:In time of running of an iternal-combustion engine, throttle valve opening data TA is taken into a control circuit 10 from a throttle sensor 6 at every specified time, and at this control circuit 10, ratios TA/TAO of the throttle valve opening data TA this time and throttle valve opening data TAO taken in the last are calculated. Next, whether this ratio is more than the specified value LVL or not discriminated, and when YES is discriminated, an asynchronous injection quantity (time) Ta is calculated by Ta alphaTA/TAO+beta (but alpha and beta are of constant), performing asynchronous injection from a fuel injection valve 11. On the other hand, when NO is discriminated, the asynchronous injections is not performed. According to this method, the overlean of an air-fuel ratio at the initial stage of acceleration is preventable and, what is more, drivability at the initial acceleration is improvable.
