Abstract: PURPOSE:To feed a motor with braking force even when the specified direction of a rotational-direction command signal is changed by nullifying the rotational- direction command signal when an inversion command signal is applied. CONSTITUTION:A flip-flop 22 detects the direction of rotation of a motor 14 on the basis of outputs from magnetic sensors 16, 18 detecting a permanent magnet for a rotor for the motor 14. A forward/counter torque control circuit 26 transmits a revolution command signal X and a voltage command signal Y over a forward/reverse control circuit 30 and a bias control circuit 32 on the basis of a rotational-direction command signal F/R, a brake command signal B, a rotational-direction detecting signal D and a control signal from a revolution control circuit 28. When the brake command signal B is transmitted, on the other hand, the rotational-direction command signal F/R is nullified temporarily. Accordingly, effective control is enabled.

Abstract: PURPOSE:To make a device lighter in weight and compact in form and contrive a higher heat-exchanging efficiency, by a construction wherein a working engine is contained in a casing provided at an upper part of a liquid tank for a heat- transmitting medium, and an engine heat radiating part is provided on the lower side of a pipe provided in a liquid surrounding the casing. CONSTITUTION:In operation of the engine 10, a heat-transmitting medium fed through a pipe 21 is compressed by a compressor 20, is fed through a pipe 22 into a condenser 23, where it is condensed, and the condensed medium is fed to an air conditioner through a pipe 25. The heat of condensation generated at the time of condensation heats water W surrounding the condenser 23, and the water W is heated also in the surroundings of an exhaust-gas heat exchanger 12 and a cooling-water heat exchanger 13 by an exhaust gas and high-temperature cooling water. The water W thus heated moves upward by convection, collects in a gap 9, and heats feed water for hot water supply contained in a pipe P. Since the volume of the gap 9 is small due to the presence of the casing 2 and the amount of water W in the gap 9 is small, the temperature of the water W is raised, and the water in the pipe 9 is heated with a high thermal efficiency.

Abstract: PURPOSE:To promote the improvement of flaw detecting accuracy, by actuating the first and second removers, which comprise a detector, lift device and a removal head equipped with plural slits removing a protrusive flaw, respectively, to both side end surfaces just before ultrasonic wave detection. CONSTITUTION:A steel plate 1 to be inspected is fed to an automatic ultrasonic detector, and if the first detector 7 detects one side end part surface, the first removal head 9, having plural slits 13, lowers by the first lift device 11 being adapted to a grinding range 20. Simultaneously, the second remover 6 moves along a rail 15 by a moving device 14 by an on-signal of the first detector 7, and if the second detector 8 detects the other side end part surface, the second removal head similarly lowers being adapted to the other grinding range 20. In this way, a protrusive flaw, generated in both the grinding ranges 20, is removed by the respective slit 13. In this way, the improvement of detecting accuracy can be promoted by preventing ultrasonic probe 16, 17 from colliding against the protrusive flaw.

IPC: G09G5/393
Filed: 1988-04-18
Abstract: PURPOSE:To obtain a compact graphic processor by setting a data converting means between a data processing means and a memory. CONSTITUTION:A time-division access is given to a memory and a converting means set between a processing means and the memory performs a converting job to turn the data into parallel ones. In other words, the data which are successively read out in time division are temporarily stored in a latch and then given to a processor as the parallel data when the data are read out. In a data writing state, the parallel data given from the processor are written successively and in time division into the memory via a multiplexer. In such a way, the transfer of data is possible via a data bus of the small bit width and therefore the number of working memory elements can be decreased. Thus a compact graphic processor is obtained.

Abstract: PURPOSE:To surely prevent a cargo from dropping off, by pivotally coupling buckets rotatably about transverse axes between a pair of endless chains so that the adjacent buckets are overlapped with each other by a drive screw near a loading position. CONSTITUTION:In a bucket conveyor 11, a large number of buckets 15 are pivotally coupled at prescribed intervals in the longitudinal direction of a pair of parallel endless chains 12 between them. An engaging member 31 projecting from a side of the bucket 15 moved to the vicinity of a loading port for a conveyed cargo during the drive of the bucket conveyor 11 is engaged with a drive screw 74 so that the bucket 15 is pushed and displaced in its moving direction A against the force of a spring 72 because the drive screw 74 is rotated in motive conjunction with the endless chain 12 through gears 80-83. As a result, the succeeding bucket 15a approaches the preceding bucket 15, and the front flange 75a of the bucket 15a is overlapped with the rear flange 75 of the bucket 15. For that reason, the cargo is loaded without dropping off through between both the buckets 15, 15a.
