An automatic control system that protects downhole equipment and surface equipment from high temperatures resulting from the breakthrough of injection vapor. The system operates to derive an estimate of the temperature of production fluid at a location upstream from the downhole equipment. An alarm signal is generated in the event that this temperature exceeds a threshold temperature characteristi...

A mobile terminal is provided that includes a housing having an opening formed therein, a cover disposed in the opening of the housing, the cover including at least one light transmission opening, an input switch located beneath the opening of the housing and the at least one light transmission opening, a light emitter to illuminate the at least one light transmission opening, and a light constrai...

FIELD: electric engineering. ^ SUBSTANCE: according to invention as shunts of accumulator negative electrodes, open-cell foam metal is used with porosity of at least 90%, structure of which is replication of open-cell polyurethane foam structure; at that lead or lead alloys coating is applied on foam metal. Since foam metal has branched open-cell structure, maximum contact of shunts with active ma...

The essence of the invention includes a hydraulic vibrator approaching the next interlayer in an interval of a layer perforation, an active medium supply into it with surface pumping assemblies operated in a alternate mode,...

PROBLEM TO BE SOLVED: To provide a compact differential limiting device that can release a differential limiting function promptly even without initial torque applying means. Ž

SOLUTION: In this differential limiting device including friction clutch members 8 and 9 for generating differential limiting force between differential members 5 and 1, there are provided elastic members 10 and 11 for...

The invention aims at preventing a clutch as a frictional engagement element from being damaged and ensuring a driver of the operation feeling even if an accelerator pedal is depressed when an automatic transmission is shifted from its driven state to its non-driven state. If a neutral position has been selected and if an accelerator has been depressed, an ECT_ECU performs normal control before th...

A golf swing exerciser uses two lengths of resistance cords or tension elements connected to an exercising handle so that one of the cords extends to an upper resistance region on a back swing side of the exerciser and the other resistance cord extends between upper and lower resistance regions on a back swing side of the exerciser. The cord from the upper resistance region resists downward moveme...

A drive power from an engine 1 is transferred to front wheel drive systems and rear wheel drive systems via a central differential 4. A torque distribution ratio between front and rear wheels defined by the central differential is set to one for the front wheels being made too much thereof, with a motor generator being coupled to the rear wheel drive systems. In response to detection signals from ...

PROBLEM TO BE SOLVED: To accurately estimate a hydraulic braking delay and hydraulic braking force. SOLUTION: Regenerative braking force BM is set at required braking force Bref from a time point P1 where the required braking force Bref exceeds a designated threshold Bref0 until a time point P2 where a hydraulic braking delay time TD elapses, and after the time TD elapses, the regenerative braking...

PROBLEM TO BE SOLVED: To easily provide a jamming resisting function through a simple design. SOLUTION: A pair of differential gear mechanisms 5 and 6 having the same gear trains 5A and 6A (5B, 6B) are intercoupled through two systems of power transmission systems A and B. A rotation power inputted to a shaft 3 is divided once and thereafter, the division powers are united together and outputted t...

PROBLEM TO BE SOLVED: To enable a long running mileage when a generator motor breaks down. SOLUTION: A hybrid type vehicle includes an engine 11, a generator motor 16, a driving motor 25 joined with a driving wheel 81, a differential gear unit, a breakdown judgment means 82 for judging whether the generator motor 16 breaks down or not, a revolution detecting means for detecting the revolutions of ...

A brake control apparatus is configured to suppress fluctuations in the deceleration when transferring from cooperative braking to regenerative braking or hydraulic braking. The brake control apparatus calculates a braking torque command value feed forward component for reaching a target deceleration corresponding to the master cylinder pressure according to an ideal reference model. The brake con...
