Abstract: PURPOSE:To provide the titled fermentation apparatus capable of preventing the contamination of the apparatus with undesirable microorganisms and keeping the fermentation stably for a long time, by filling the upper space of a closed prefermentor, a main fermentor and a clarifier with alcohol vapor emitted from the clarifier. CONSTITUTION:Sterilized air is blasted through an aeration wheel 10 into a prefermentor 5, and diluted sugar syrup is introduced through the pipe 19 into the prefermentor, by energizing the motors 9 and 29. Yeast is proliferated in the sugar syrup. The fermented liquid is sent to the first main fermentor 2 through the holes 13 by its own weight, and then transferred successively to the second and the third main fermentors 3 and 4. The unrefined sake produced in the fermentor 4 is transferred to the clarifier 1, and the impurities deposited on the bottom plate of the clarifier 1 is discharged through the waste chamber 24 and the pipe 25. The clear alcohol fermentation liquid is obtained through the overflow pipe 23. The space upon the clarifier 1 and the fermentors 2 and 3 is covered with a sealing plate 6, and is filled with alcohol vapor evaporated from the alcoholic liquid in the clarifier 1 to prevent the space A from the contamination with undesirable microorganisms.

Abstract: This steering column having a cylindrical tubular body (1) of circular cross-section comprises a profiled part (8) forming a locking device. In this part (8) longitudinal grooves (10) having a width which corresponds to that of a locking sliding bolt have a depth at least equal to the thickness of the wall of the initial tube and are separated by solid ribs (12). On the inner face of the device (8) circular projections delimit V-grooves between them, whose peaks correspond substantially to the mid-part of the ribs. Each rib (12) thus has sufficient strength to counteract the torque exerted during an attempted theft. Each groove can receive the sliding bolt in one locking position. The column comprises at least two grooves (10). <IMAGE>

Abstract: An example of the apparatus is a portable video tape recorder. The transducer (28)-to-tape (130) velocity is controlled by a rotary member such as a capstan, turnable or headwheel (22). Motion of the recorder may cause accelerations or variations in velocity of the headwheel (22) which affect the regular spacing on the tape of sync or timing signals transduced thereto. Regular spacing of sync signals is desirable for good reproduction on playback. Timing or sync signals generated by a signal generating wheel (34) coupled to the headwheel (22) are used to control the application of the video timing signals to the transducer, thereby making the spacing regular. In the combined recorder and camera, the timing signals from the generating wheel (34) control the image scanning (76, 56) in the camera and also the chroma production (65, 58). In another example, video signals are written into a digital memory and read out of it at a rate determined by the timing signals from the generating wheel.

Abstract: PROBLEM TO BE SOLVED: To provide a visual examination apparatus of a tablet capable of detecting the peel flaw of the tablet like a sugar-coated tablet. SOLUTION: Multivalue data obtained by photographing a tablet to be inspected is binarized on the basis of a predetermined threshold value to obtain a binary image (S1). Thereafter, the tablet is demarcated into a center part and a peripheral edge part to specify a connection component considered to correspond to the peel part of the tablet specified by binarization (S5). When the specified connection component does not meet a predetermined judge value X1, the tablet is judged to be a superior one (S6, S7). In the case of the judge value X1 or more, the tablet not meeting a predetermined judge value X2 (>X1) at the center part thereof is removed to be judged to be a defective one (B8-S10). By this constitution, peel inspection can be stably performed with high accuracy.

Abstract: The values of incorrect samples of, for example, a digital audio signal are estimated by means of interpolation. For this purpose an appropriate sampling interval is determined from the number of incorrect samples, in which interval the incorrect samples are situated. Subsequently, a best-fitting recursion formula is determined from the values of the samples, a first estimate being taken for the values of the incorrect samples. By means of this recursion formula the value of a sample is expressed as a weighted sum of the values of a number of preceding samples and an error term. By means of the recursion formula thus found the values of the incorrect samples are subsequently estimated, in such a manner that they are best-fitting values for the recursion formula. The Application also discloses a device for carrying out the method.

Abstract: PURPOSE:To reduce non-actuation of a protecting means by providing a human body protecting means at the time of collision, a means to drive the protecting means in accordance with an impact level and a driving condition changing means to mitigate a driving condition of the driving means at the time to avoid collision. CONSTITUTION:An acceleration signal 21a from a G sensor 21 is integrated by an integrator 221 of an air bag unit 22, and it is input to an air bag motion judgement part 222. This judgement part 222 compares the integrated value with a specified threshold level and, at the point of time when the integrated value becomes larger than the threshold level, outputs an air bag actuation signal 222a to a changeover switch 223.

Abstract: Reception SIR calculation section 107 calculates a reception SIR using a value obtained by averaging interference signal power over several immediately preceding consecutive slots. Reference value decision section 109 decides whether the reception SIR is greater than a reference value or not. In the case where the count of desired signal power stored in power value storage section 108 satisfies a count necessary for averaging and at the same time the reception SIR is not greater than the reference value, TPC creation section 110 creates a TPC to instruct a decrease of transmit power and creates a TPC to instruct an increase of transmit power otherwise. This allows the base station to constantly receive signals of sufficient quality and perform efficient communications. <IMAGE>
