Patent JP-H0641694-B2 (JP)
Inventor: KURISUTOFUAA OO MIDORUTON
IPC: E02F5/14
Filed: 1989-06-09
Abstract: A method and apparatus for automatically controlling the depth of earth grading for utilization with a grader or paver (30) is disclosed. The method includes determination of time taken for an acoustic pulse to travel from a transducer (10) to a reference surface and back, with this value being used to calibrate a microprocessor-controlled distance-measuring device (100). As the grader moves over a surface to be graded, the distance to the reference surface is constantly detected by a repeated emission and detection of such acoustic pulses. The timing of the echoed pulses is converted to addresses in a look-up table which contains control words symbolizing commands to be given to hydraulic rams carried by the grader. By implementing these commands, the depth of the blade (40) relative to the reference surface is constantly updated, compensating for variations with the height of the reference surface. A thermistor is provided to automatically compensate for temperature variations as the grading takes place. Displays are provided for the operator of the vehicle to show what type of adjustments are being made to the blade, and whether the height of the reference surface is outside the range of sensitivity of the follower. The follower is automatically calibrated for a given blade depth by repeated incrementation of a delay time variable until a zero adjustment command is generated for the blade control.

Abstract: A heating arrangement in a fixing station of a printing device has its operation monitored by an arrangement in which a measuring element is disposed in series with the heating element and a switch element. The measuring element is traversed by the heating current and emits a corresponding voltage which is supplied to an amplifier circuit which produces pulse-shaped clock signals as long as the heating current flows through the measuring element and the heating element. The clock signals are supplied to a reset input of a flip-flop whose dynamic input is connected to an oscillator operating at a frequency lower than that of the alternating current so that as long as clock pulses occur, the flip-flop is constantly reset. Therefore, the flip-flop can only be set over a longer interval when no heating current is flowing. If heating current flows although no heating current should flow, the same is identified by a counter whose counting input is connected to the amplifier circuit and whose reset input is connected to a heat sensor. Therefore, an undesired heating current through the heating element causes operation of the counter. A set flip-flop or a counting counter indicate malfunctions of the heating arrangement.

Abstract: PURPOSE:To improve the utilizing efficiency of frequency by selecting a radio zone to be the candidate of the selection of other zones by the peripheral zone supervision of a mobile station, and assigning a radio channel by a radio base station as considering all the radio zones of the candidates to be objects. CONSTITUTION:A control channel 28 informs the mobile station 22 of the frequency of the control channel 29, and the mobile station 22 switches the frequency cyclically to the informed frequency, and measures the received level of a base station being overlapped 24. Since the mobile station 22 is located in the overlapping area of the radio zone 25 and the radio zone 26, the received level of a supervisory channel becomes maximum, and it is decided that the base station 24 can be connected to it, and the base station 23 inquires the base station 24 about whether there is the usable radio channel or not through a data line 27. At such a time, when there are plural base stations of the connectable candidates, it continues inquiry in the order of the large received level until the usable radio channel is found out, and the radio channel of the maximum received level is selected.

Abstract: An arrangement for sealing the gap between two mutually concentric machine parts (52, 56), which move with respect to one another, comprises a sealing ring (53) which is inserted in the slot (51) of a first machine part (52) and consists of tough elastic plastic, and which rests with sealing edges (57, 58) arranged close to its ends on a second machine part (56), and a clamping ring (54) which is arranged between the sealing ring and the base of the slot, stresses the sealing ring radially and consists of an elastomer material whose axial expansion is less than that of the sealing ring. In this case, fixing the clamping ring (54) in the centre of the sealing ring (53) causes difficulties. 
<??>In the sealing arrangement according to the invention, the sealing ring (53) has an annular slot on its surface facing the slot base (63), which annular slot holds the clamping ring (54) and has an essentially trapezoidal cross-section, and the sealing ring (53) moreover has a least one radial hole (67) connecting the space (71) between the sealing edges (57, 58) and the base of the annular slot. In consequence, the clamping ring (54) is not only fixed correctly with respect to the sealing ring (53) but also ensures good stress relief of the sealing ring (53) while at the same time avoiding the sealing ring lifting as a result of excess pressure building up between its sealing edges (57, 58).

Abstract: An improved version of applicant's prior bulldozer mold board assemblies is disclosed. Such prior assemblies include a mold board (16), a reciprocating cutter blade (18) along the lower edge of the mold board, and a resonant beam mounted aft of the mold board. The vibration of the beam results in a reciprocating force at the node, which is undesirable in applicant's prior device. The present invention improves on applicant's former construction by pivotably supporting the mold board so that the mold board is pivotable about a transverse axis. The resonant beam is connected at its central node to the mold board. In this fashion, and reciprocating transverse forces on the node of the resonant beam are transmitted to the pivotably mounted mold board to agitate the material in contact therewith.

Abstract: In accordance with the invention, a speech recognizer is provided which uses a computationally-feasible method for constructing a set of Hidden Markov Models (HMMs) for speech recognition that utilize a partial and optimal degree of mixture tying. With partially-tied HMMs, improved recognition accuracy of a large vocabulary word corpus as compared to systems that use fully-tied HMMs is achieved with less computational overhead than with a fully untied system. The computationally-feasible technique comprises the steps of determining a cluster of HMM states that share Gaussian components which are close together, developing a subset codebook for those clusters, and recalculating the Gaussians in the codebook to best estimate the clustered states.

Abstract: The amount of N2O emission from a fluidized bed reactor is reduced by adding a hydrogen radical providing additive (e.g. a hydrogen containing fuel such as natural gas or alcohol) to the flue gases discharged from the fluidized bed. Sufficient oxygen is present in the flue gases-either by addition with the additive, or by addition of an excess to the combustion chamber-so that the additive reacts with the oxygen, typically raising the temperature of the flue gases (e.g. from about 700 DEG -900 DEG  C. to about 950 DEG -1100 DEG  C.) so that N2O production is reduced about 10-90%. The additive may be injected in or just prior to a cyclone for separating particles from the flue gases.
