Title: Knocking controller of internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: G01L23/22
Filed: 1986-07-14
Abstract: PURPOSE:To enable complete knocking detection by mounting both knocking sensors possessing different characteristics among them and a plurality of knocking detecting system containing a frequency filter, a reference voltage generating means. CONSTITUTION:The knocking detecting pulses generated from both a comparator 56 in a primary knocking detecting system 100 and a comparator 66 in a secondary knock detecting system 200 are converted into the OR signals, respectively in an OR circuit 70 and then sent to an integrator 7. Since said integrator 7 generates control voltages according to input pulses, if a knocking is detected from either the primary or the secondary knocking detecting system, the integrator 7 will generate a control voltage to make delay control for the ignition timing so that the engine knocking may be restrained. The respective characteristics of acceleration sensors 51 and 61, frequency filters 52 and 62 and noise level detectors 55 and 65 are changed to different ones in each of the knocking detecting systems so that said characteristics can be modified to the optimum characteristics in respective knocking detecting systems, whereby accurately detecting any knockings in all cylinders of an engine by the characteristics of each of the knocking detecting systems.

IPC: C22B1/20
Filed: 1981-10-21
Abstract: PURPOSE:To control carbon distributions and grain size distributions and to prevent the breakdown of spurious particles by providing an angle changeable chute between a roll feeder and a sloping chute, and changing the angle of the chute. CONSTITUTION:An angle changeable chute 10 is provided between a roll feeder 2 and a sloping chute 3, and the raw materials in a hopper 1 are delivered by the feeder 2 and are dropped on the chute 3 through the chute 10 so that the materials glide down on the chute and accumulate on a pallet 5, whereby ore layers 4 are formed. If the angle alpha of the chute 10 is taken samll, the impact when the raw materials drop onto the chute 3 is relieved and the breakdown of spurious particles is decreased. Since the gliding distance is made longer by said adjustment, the carbon and materials of small grain sizes segregate in the upper layers of the layers 4. Thus the yield of sintering is improved and quality is stabilized by determining the angle alpha properly according to sintering conditions.
