Inventor: MINAMITANI KUNIKIMI
IPC: G01F1/68
Filed: 1987-01-27
Abstract: PURPOSE:To detect suction air amount with high accuracy, by judging the deterioration of a hot wire from the shift of a reference output characteristic from a hot wire output characteristic and correcting characteristic shift to the suction air amount. CONSTITUTION:An engine control apparatus 20 reads suction air amount Qa, the number Ne of rotations of an engine and a throttle opening degree (w) by an air flow sensor 2, an ignition coil 6 and a throttle opening degree sensor 13 after initial setting and reads the fundamental air amount Q0 to the number Ne of rotations and the opening degree (w) from the fundamental air amount map in RAM 22. The air amount Q0 is compared with the air amount Qa to calculate a shift ratio and the angle of inclination to the air amount Qa is calculated. Then, the samplings of air amounts at respectively low and high sucking times are finished and, when a predetermined amount of shift is detected, the deterioration of a hot wire is judged. The air amount Qa at that time is corrected on the basis of the air amount Q0 and the angle of inclination, and the deterioration of runnability and the lowering in the reliability of the engine are prevented.

Title: Testing method of temperature rise of transformer
Inventor: HAYAKAWA MITSURU
IPC: H01F41/00
Filed: 1990-01-25
Abstract: PURPOSE:To execute a temperature rise test by using a tap-difference conversion load method in a state close to a rated voltage and a rated current by a method wherein, when a required circulating current cannot be obtained, a dummy load is connected to secondary sides of transformers which are operated in parallel and a secondary-side circulating current flowing in a transformer under test is superposed on a dummy load current effectively. CONSTITUTION:When a difference voltage (e) which circulates a required secondary-side circulating current 12 cannot be obtained, a dummy load XC is connected to secondary sides of transformers TL, TR which are operated in parallel. When output voltages E2 at the secondary sides are used as a reference vector, the vector of the circulating current I2 flowing in the transformer TL is advanced by nearly 90 deg. from an output voltage E2, and the vector of the circulating current I2 flowing in the transformer TR is delayed by nearly 90 deg. from the output voltage E2. A dummy load current I2CL of the circulating current I2 flowing in the transformer TL show a nearly identical phase; a dummy load current I2CR of the circulating current I2 flowing in the transformer TR show a nearly opposite phase. Thereby, the dummy load currents I2CL and I2CR are superposed on the circulating currents I2 flowing in the transformer T1 and TR. A lack of the circulating current flowing in the transformer TL under test can be supplemented by the dummy load current I2CL.

IPC: D05B21/00
Filed: 1989-01-27
Abstract: PURPOSE:To eliminate surplus idle stitches by providing a stitch-back function for commanding the stop of a machine motor and moving an embroidery frame by the displacement calculated after the stop of motor when the actual speed of the machine motor reaches predetermined low speed. CONSTITUTION:When breakage of an upper thread is detected, a motor is set to extremely low speed and the displacement of a return frame corresponding to the number of idle stitches from a stitch position when the motor is stopped lifting a needle to a leading position of overlapping stitches is calculated in synchronization with a needle lifting signal. When the actual speed of the motor is predetermined one, a stopping command is generated and a stitch-back function for moving an embroidery frame by the calculated displacement after the stoppage of the motor is carried out. Thus, in the stitch-back operation at the breakage of upper thread, the stitch if neither loosened at the case of the least number of stitches, nor viewed unnatural at the case of the largest number with respect to the number of stitches in the overlapping stitch portion. Also, with respect to the number of idle stitches, only the number of idle stitches corresponding to the specified speed of the machine motor before the detection of breakage can be idly stitched, so that the proper overlapping stitches can be obtained.
