Title: Detection device for shaking separator
Inventor: TOKI HARUMITSU
IPC: B07B13/14
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a composite detection device using a single sensor for a shaking separator. SOLUTION: A light of a wavelength to be absorbed by moisture and a light of a reference wavelength not to be absorbed by moisture are emitted to rice grains under separation on a shaking separation plate from an unhulled rice/unpolished rice identifying sensor. Thus it is identified whether the rice grain is an unhulled rice or an unpolished rice by judging the difference between the detected voltage values of the light of a wavelength to be absorbed by moisture and the light of a reference wavelength, and thereby, the border positions of the unhulled rice and the unpolished rice. In addition, it is judged whether there is the fluctuation of the shaking separation plate based on whether there is the periodic change in the detected voltage value of the light of a reference wavelength.  Consequently, it is possible to detect the border positions of the unhulled rice and the unpolished rice and the presence of the shaking at the same time, with the help of the unhulled rice/unpolished rice identifying sensor, and simplify the construction of the detection device and further, reduce a manufacturing cost on the device.

Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent degradation of catalyst due to combustion of unburned fuel gas generated by miss fire caused by lowering of fuel pressure within catalyst and to secure minimum traveling in a range without adversely affecting catalyst. SOLUTION: Fuel pressure kpa and a set value Pa0 are compared (S2). At the time of kpa<Pa0, a fuel pressure lowering ratio Δkpa per unit time is calculated (S4). According to an increase in the fuel pressure lowering ratio Δkpa, the fuel cut cylinder number is increased (S5 to S11). Because the fuel cut cylinder number is changed according to the fuel pressure lowering ratio Δkpa without suddenly cutting whole cylinder fuel, even if lowering of fuel pressure is detected, minimum traveling in a range without adversely affecting catalyst is secured.
