Title: Knocking detecting method
Inventor: IKEDA SHINJI
IPC: G01M15/00
Filed: 1981-05-22
Abstract: PURPOSE:To detect knocking from pressure variation within a low frequency range without providing a special circuit by detecting the pressure in an engine combustion chamber, and then detecting the knocking from the value obtained by imposing secondary differentiation upon the pressure in terms of a crank angle or time. CONSTITUTION:The pressure in an engine combustion chamber is detected and the value obtained by imposing secondary differentiation upon the detected pressure interms of a crank angle or time is used to detect knocking. After the pressure (p) in the combustion chamber with the crank angle theta of, for example, 0- 720 degrees is stored in a storage part via an A/D converter, when it is judged in a step 22 that knocking (d<2>p/dtheta<2>>k) exceeding prescribed amplitude, an ignition point of time is set to a knocking limit in steps 23-25. In a step 27, when the (p) is judged to be thetapmax 18 deg. ATDC, MBT feedback control is performed in steps 28 and 29, and when not, the ignition period is advanced by a 1 deg. crank angle in a step 30 at 400ms intervals.

Title: Automatic temperature controller and method therefor
Inventor: TAJIMA KENJI
IPC: G05D23/00
Filed: 1988-03-29
Abstract: PURPOSE:To prevent a frequent variation of an in-warehouse temperature by comparing a level of an output from an in-warehouse temperature sensor with a reference level from a reference level generating circuit and controlling an operation of a cooling equipment or a heating equipment, based on a result of this comparison. CONSTITUTION:The title device is constituted so that in case an out-warehouse temperature has been varied, a reference temperature is not varied in accordance therewith immediately but the reference temperature is varied under some prescribed condition against a variation of the out-warehouse temperature. For instance, the variation of the out-warehouse temperature is detected with some temperature width, and when it is within its temperature width, the reference temperature is made constant irrespective of the variation of the out- warehouse temperature. Or based on an average value in a unit period of the out-warehouse temperature, the reference temperature is controlled. In such a way, an in-warehouse temperature follows up a temperature variation extending over a long period of time such as a variation of a season, but does not follow so much a temperature variation in a short time such as a temperature variation in a day.
