63results about How to "Reduce work speed" patented technology

A handheld work apparatus has a drive motor which drives a work tool rotationally via a belt drive. The belt drive has a first, driving pulley and a second, driven pulley. The second pulley is connected fixedly to the work tool so as to rotate therewith. The rotational speed of the second pulley is lower during operation than that of the first pulley. A brake unit acts on the belt drive. A first drive belt of a first stage and a second drive belt of a second stage act between the pulleys to transfer the drive torque. The belts each bring about a rotational speed reduction. The belt drive includes a redirection roll which bears against the belt, via which the highest drive torque is transmitted during operation. As a result, a braking operation of the work tool is enabled independently of the rotational speed of the tool.

A single event transient-resistant reinforced register suitable for an SRAM type FPGA for aerospace is disclosed. A register unit performs processing on a SET pulse by a novel delay unit to make the register have high SET capability. The reinforced register consists of four parts of an internal data and clock generation circuit, a master latch, a slave latch and an output buffer. The internal data and clock generation circuit uses an NAND gate and an NOR gate to form a delay chain for processing the SET pulse; and the master latch and the slave latch use a latch unit based on a DICE (Dual Interlocked storage CEll) structure. The reinforced register, by using inherent characteristics of a DICE unit, only uses one delay chain to shield the SET pulses in a clock terminal CLK and a data terminal D at the same time. Compared with a conventional SET reinforced register, the reinforced register provided by the present invention has fewer delay units, so that the overall area of the reinforced register is smaller than that of the conventional reinforced register.

The mode selection part (700e) is turned on when the mode selection instruction selects the economic mode, and outputs the engine speed correction value ΔN0 (ΔN1=ΔN0) calculated by the engine speed correction value calculation part (700d), and the subtraction part (700f) calculates the engine speed correction value ΔN0 from the rated value. Corrected engine speed ΔN1 is subtracted from target speed Nmax to obtain target engine speed NR2. A calculation unit (700d) calculates an engine rotation speed correction value ΔN0 corresponding to the pump discharge pressure average value Pm. In the memory table, the relationship between Pm and ΔN0 is set as follows: when Pm is below PA near the intermediate pressure, ΔN0 is 0, and when Pm is higher than PA, ΔN0 increases with the increase of Pm. Accordingly, through mode selection, the prime mover speed can be reduced to improve fuel consumption, and at the same time, in the necessary load area, the performance degradation caused by the reduction of pump discharge flow can be reduced, and the prime mover speed or pump discharge flow will not be discontinuous.
