Title: Power transmission controller in harvester
Inventor: INADA TETSUYA
IPC: A01D69/00
Filed: 1988-06-29
Abstract: PURPOSE:To enable realization of prescribed stable control without causing hunting phenomena by setting a dead zone width at a larger value than a variation range of a car speed corresponding to the variation range of a reaping part speed on a speed change pattern. CONSTITUTION:The value of a larger dead zone width than a variation range of a car speed corresponding to a variation range of a reaping part speed on a speed change pattern is previously memorized and set in a central controller 25. If the variation range ( V) in changing from a car speed (V0) suitably sensed for each time to (V1) is larger than the dead zone width, a driving command, such as driving to the acceleration side or deceleration side of a stepping motor 22, is practiced. Contrary thereto, if the variation range ( V) in changing from the car speed (V0) to (V1) suitably sensed for each time is smaller than the dead zone width, a command without driving the stepping motor 22 is issued from the central controller 25 without practicing comparison and judgment on the speed change pattern. Thereby, hunting phenomena in control can be prevented even in the case of variation in load on the threshing part or running.

Abstract: PURPOSE:To enable utilizing heat with greater efficiency by providing a water-cooling jacket in the lower part of a primary combustion furnace, an air-feeding pipe in the water-cooling jacket, and a plurality of steam-producing pipes in a secondary combustion furnace. CONSTITUTION:A circulation channel (steam-producing pipes) 40 comprises a water- feeding pipe 41 into which warm water is sucked from a heat-accumulating tank 13 and fed, a conduit 43 which conveys warm water fed from the water-feeding pipe 41 to a secondary combustion furnace, and steam-producing pipes 44 provided in the secondary combustion furnace 12. The temperature inside the secondary combustion furnace 12 rises as high as about 1,800 deg.C and by this combustion the warm water drawn into the circulation channel 60 is turned into steam virtually instantly and flows back into the heat-accumulating tank 13. This is because the circulation channel 40, comprising ring pipes 45 and a plurality of steam-producing pipes 44, transmits the heat in the surroundings instantly to the warm water inside and raises its temperature rapidly. With flow of steam in a rapid jet, the temperature of the warm water reaches to about 80 deg.C in a relatively short time. This warm water is returned to the circulation channel 40 again so that the temperature of the heat-accumulating tank 13 will soon rise to 100 deg.C and be utilized for driving a steam turbine.

Title: Matched filter for analog input
Inventor: MATSUMOTO KATSUHEI
IPC: H03H17/02
Filed: 1978-12-27
Abstract: PURPOSE:To realize a matched filter which provides high-speed data transmission with S/N maximized at the time of sampling, by adding a resistance and switch to a noise filter and then by controlling the switch in address ready mode. CONSTITUTION:A noise filter consists of series-connected resistance 8 and switch 9, and resistance 1 connected together in parallel. Switch 9, on the other hand, is turned ON-OFF by address-ready signal C from parallel-series converter 6 to change time constant (tau) of matched filter 10 over between two stages. Nearly at the switching time of analog inputs i1-in when address-ready signal C is zero, switch 9 is turned ON to insert resistance 8, and consequently even if noise would be left more or less, the time constant is decreased to shorten the response time. Around the sampling time of A/D converter 5 when address-ready signal C is one, switch 9 is OFF to increase the time constant for the maximization of SN, so that noise will completely be removed. Therefore, even if data transmission is increased in speed, the rounding of waveform never occurs.
