Title: Speed control device for automotive motor
Inventor: UEKUSA YASUYUKI
IPC: H02P7/29
Filed: 1981-02-09
Abstract: PURPOSE:To reduce the vibration noise of a blower fan motor for an automotive air conditioner by converting a duty signal calculated and produced by a microcomputer into a frequency being higher than an audible frequency, thereby controlling the speed of the motor. CONSTITUTION:A blower fan motor 15 is controlled at its speed by varying the dusty ratio of a duty signal S2 produced by a microcomputer 10. A triangular wave oscillator 20 produces an output S1 having a constant frequency and amplitude being higher than audible frequency, and preferably higher than approx. 30kHz. The signal S2 is smoothed by a smoothing circuit 30 to become a smoothed signal S3. A comparator 40 receives the signals S1 and S3 and outputs a pulse S4 which becomes ON when the level of the signal S3 is larger than the level of the triangular wave S1. A pulse S4 drives the motor 15 through transistors 13, 14. Accordingly, the duty ratio of the pulse S4 is set to a frequency higher than the audible frequency in response to the signal S2, thereby preventing an operator from hearing the vibration noise.

Abstract: PURPOSE:To exclude erroneous operation accompanied by manual switching operations, by correlating the measured data of inputted water contents and loads with associated tables in a memory part, judging the kind of sample grain, and automating the switching operation of equipment in correspondence with the kind of the grain. CONSTITUTION:Sample grain is mounted on a central part 6a of a lower electrode part 6. An upper electrode part 4 is lowered, and a load is applied to compress the sample. The load is detected and measured by a load sensor 42 comprising a gage 18. The load value and the water content value of the sample, which is measured by the upper and lower electrode parts 4 and 6, are sent to a multiplexer 32 and further sent to a CPU36 through an A/D converter circuit 34. The grain A, B... correspond to the measured data M of the inputted water contents. The measured data Wa, Wb... of the loads for the kinds of grains are compared with the actually measured load data W. For example when W=Wa, the measured data M of the water content is converted into the water content value Ma of the grain A. By the series of operations described above, the result that the sample to be measured is the grain A and the water content value is Ma is obtained.
