Abstract: Compatibilities between a double-sided optical disk and a single-sided optical disk are assured when each disk is subject to data recording and reproduction operations by means of either a one-head type optical data recording and reproduction apparatus or a two-head type optical data recording and reproduction apparatus while allowing vertically inverted cartridge insertion for data recording and reproduction. Provided is an optical disk having a data recording area (25) and a volume management area (26) which includes an access mode registration area (27) for recording therein access mode data such as apparatus data representing the number of optical heads of the optical data recording and reproduction apparatus, the number of volumes of an optical disk, and sector recording order and/or track and sector recording units. Data recording and reproduction operations are effected by detecting the optical head (4A, 4B) facing each recording surface by means of a sensor (28), rotating the optical disk (1) forwardly or reversely, reading out access mode data from the access mode registration area (27), and switching signal paths between a channel data recording and reproduction circuit (7) and a laser drive circuit (8) and a signal reproduction head amplifier circuit by means of a signal selection circuit (18).

Abstract: A pattern recognition technology includes a set of control signal vector and covariant matrix having respective states of a reference pattern of an objective word for recognition, which reference pattern is expressed by a plurality of states and transitions between the states, and transition probabilities between respective states. A prediction vector of t th feature vector is derived on the basis of the t-1 th feature vector and the control signal vector. A feature vector output probability for outputting the t th feature vector in n th state of the reference pattern of the objective word for recognition is derived from multi-dimensional gaussian distribution determined by the prediction vector and the covariant matrix with taking the prediction vector as an average vector. A word output probability for the reference pattern of the objective word, outputting the feature vector sequence of the input signal employing the feature vector output probability and transition probabilities contained in respective states of the reference pattern, is derived. One of the word output probabilities having the maximum probability as a result of recognition of the word among all of the word output probabilities derived with respect to the objective word is output.

Abstract: This invention provides a connector which can receive a terminal member easily and positively. In the connector, a retainer 10 is provided on each engaging portion 12 with a guide ramp face 20 which is opposed to a cavity 2 at a temporary locking position. A terminal member 30 is pushed into the cavity 2 when the retainer is at the temporary locking position. The member 30 does not enter into an opening 6 on account of the correcting action of the guide ramp face 20, even if the terminal member 30 is pushed toward the opening 6. After the distal end of the terminal member 30 passes over the guide ramp face 20, and outer periphery of the terminal member 30 is pushed down by a front end of the face 20. Consequently, the terminal member 30 is prevented from entering into the opening 6 and moves in the proper passage.

The oil pressure of the hydraulic servo is reduced, when the vehicle is in the stop state, to establish a neutral control state in which the clutch is released. Further comprised are: release state establishing means for establishing the released state of the clutch by reducing the oil pressure to be fed to the hydraulic servo when the stop state of the vehicle is detected; and complete apply state establishing the completely applied state of the clutch by boosting the oil pressure to be fed to the hydraulic servo when the shift of the vehicle from the stop state to the start state is detected. The release state establishing means includes: differential rotation calculation means for calculating the differential rotation between the input R.P.M. and the output R.P.M.; differential rotation change decision means for deciding whether or not the differential rotation has changed; pressure boosting means for boosting the oil pressure to be fed to the hydraulic servo if it is decided that the differential rotation has not changed; pressure reducing means for reducing the oil pressure to be fed to the hydraulic servo if it is decided that the differential rotation has changed; and base pressure storage means for storing a storage unit with the oil pressure before educed, as a base pressure, when the oil pressure to be fed to the hydraulic servo is boosted by the pressure boosting means and then reduced by the pressure reducing means. The complete apply state establishing means includes: first clutch pressure boosting means for boosting the oil pressure to be fed to the hydraulic servo, by adding a shelf pressure set to the base pressure, till the clutch comes into a partially applied state after the shift of the vehicle from the stop state to the start state is detected; and second clutch pressure boosting means for further boosting the oil pressure to be fed to the hydraulic servo, till the clutch comes into a completely applied state after the partially applied state.

Abstract: A load-sensing active hydraulic control device is disclosed in which a plurality of cylinders (19,20) are connected in parallel and fed with hydraulic fluid from a variable discharge pump (1), thereby to control the variable discharge pump depending on horsepower constant control characteristics and which is capable of preventing, when one cylinder (20) is increased in load pressure, actuation of the other cylinder (19) from being stopped due to a decrease in the amount of hydraulic fluid discharged from the pump. A pilot valve (25) is provided which is changed over by a pressure actuation of a passage (18) of the one cylinder (20). The pilot valve is open to communicate a pilot chamber (4b) of a change-over valve (4) with a tank (T) when a pressure in the passage approaches a set pressure of an overload relief valve (22) of the passage. This results in a degree of opening of a variable orifice (6) of the change-over valve being reduced to decrease the amount of hydraulic fluid fed to the cylinder (20), thereby to ensure feeding of hydraulic fluid to the cylinder (19) correspondingly.

Abstract: Methods and apparatus are disclosed for using current detection in a test instrument to ensure validity of component test output. In a component test instrument that employs digital synthesis of a test stimulus waveform, voltage scan data and current scan data are successively acquired, the scan data being synchronized relative to the test stimulus waveform. The voltage and current scan data are stored in respective temporary storage buffers. Before displaying the data, a check for an open lead is conducted in a manner similar to a current scan. A zero current value indicates an open lead and the acquired scan data is disqualified from being displayed. Similarly, at the beginning of a component test operation, an open lead test is performed and the first voltage scan is deferred until a validity check confirms that the test leads or probes are in place. The disclosed methods and apparatus ensure that only valid data is displayed to the user.

Abstract: Air is separated in a distillation column 30 into an oxygen-rich liquid bottom fraction and a nitrogen-rich head vapour fraction. A stream 50 of the oxygen-rich fraction is partially vaporised in a vaporiser 54 and subjected to phase separation in a phase separator 56. The resulting liquid phase 58 is reduced in pressure by passage through valve 60 and employed to cool head condenser 42 which condenses a part of the nitrogen rich head fraction to provide reflux for the column 30. A stream of vapour 62 flows from the phase separator 56 and is expanded by a turboexpander 64 with the performance of work. Nitrogen product is withdrawn from the top of the column 30 as stream 68. In an alternative embodiment (Figure 2) the stream 50 is divided, one part flowing to the valve 60 without being partially vaporised, and the other part being totally vaporised and sent to the turboexpander.

transmission frame was actually received is the same as that
indicated by the flag in the received transmission frame or not,

transmission frame was actually received is different from that
indicated by the flag above, the network controllers send the
transmission frame including an error report indicating the
loop direction to the network manager.
