Abstract: A lignocellulose material is cooked by means of an alkaline cooking liquor containing polysulfides in the presence of a quinone-hydroquinone compound, of which the oxidation-reduction potential in the form present during the cooking, which potential is a value calculated as a standard oxidation-reduction potential (Ea) with a hydrogen ion activity of 1, is within a range of from 0.12 to 0.25V to the standard hydrogen electrode potential. It is thereby possible to cook the lignocellulose material with a low Kappa number and in good yield and at the same time, to reduce the amount of the chemical solution used and to reduce the load on a recovery boiler.

An outer mouthpiece 16 disposed at the lip side is connected via a connecting shaft 28 to a shaft 26, which is a force measuring portion of the force measuring device 11 while an inner mouthpiece 14 disposed at the side of a tooth row is connected to a main body 34 of the force measuring device 11 via a connecting shaft 22 and a mouthpiece-mounting bracket 38. When the mouthpieces 12 are disposed between the lower lip, teeth and gum and the lips are closed, the outer mouthpiece 16 is pulled by the lip. The force pulling the outer mouthpiece 16 is the lip pressure, and the lip pressure at a rest position and the maximum lip pressure (the pressure of a tongue when the mouthpieces 12 are disposed at the side of a body of tongue) of an examinee are displayed on a display 36 of the force measuring device 11.

Abstract: In a method for controlling a tire vulcanization of a vulcanizing apparatus, an initial green tire temperature is measured before vulcanization and a tire temperature during vulcanization is estimated on the basis of the thus measured initial tire temperature. In addition, a sum of products of vulcanizing rates derived from the thus estimated tire temperature is calculated so as to stop the tire vulcanization when the sum of products of vulcanizing rates becomes equal to a predetermined value. Therefore, the vulcanizing rate controlling can be performed in an easy and accurate manner without measuring the tire temperature during vulcanization, and thus a trace of a thermometer insertion is not remained on the vulcanized tire surface.
