Title: Numerical controller
Inventor: MARUYAMA JUICHI
IPC: G05B19/416
Filed: 1989-02-20
Abstract: PURPOSE:To enable curved path interpolation for controlling the moving position of a movable part properly by calculating acceleration by a speed calculation part so that normal acceleration to be generated corresponding to the curvature of a locus is less than a permissble value. CONSTITUTION:A curve interpolation calculation part 2 calculates coordinate data on the moving point P(t) of the movable part by using the moving speed F outputted by the speed calculation part and fine segment data  >Xk sent from a command input part 1. The moving speed F of the path in the section connecting optional points Pk and Pk+1 on the path is determined by using segment data  >Xk-1,  >Xk, and Xk+1 of the section (k) and its peripheral sections and the maximum speed command value F0 so that the quantity of direction variation in the moving speed in the section (k) per unit time, i.e. normal acceleration is less than the permissble value. The coordinate data on the moving point P(t) of the movable part are calculated form the moving speed F and the segment data  >Xk (k=1 - n-1) in the section (k) t control the moving position of the movable part in order. Consequently, the curve path interpolation is performed at high speed with high accuracy corresponding to requested accuracy.

Title: Electrical hot air heater
Inventor: WADA KENICHIRO
IPC: F24H3/04
Filed: 1989-02-20
Abstract: PURPOSE:To reduce an internal accumulated heat collected at a lower part of a guard of an upper surface of a case so as to restrict an increasing of temperature of a hot air discharging hole and then to improve a convection heating efficiency by a method wherein a protective device composed of a honeycomb body is installed at a top surface of the case over a heater unit. CONSTITUTION:A heated air discharging hole 1a is opened at a top surface of a main body case 1 and this hot air discharging 1a is provided with a guard 6 composed of an aluminum honeycomb body. This guard 6 is made such that a thin aluminum foil is adhered and formed with adhesive agent to form a hexagonal column (cell). Since the guard 6 has quite a high rate of opening of 90 to 99%, ascending air stream passes through the guard 6 smoothly. The hot air is not accumulated near the hot air discharging hole 1a, so that it is prevented from being increased up to a high temperature and further the hot air is discharged smoothly, resulting in that a convection heating capability can be increased.

IPC: G01F1/00
Filed: 1989-02-21
Abstract: PURPOSE:To correctly detect suction air capacity of an engine by a method wherein a detected value of an air capacity sensor provided on the upstream of a supercharger is compensated based on the variation in supercharged pressure on the downstream of the supercharger. CONSTITUTION:A flow is carried out per specific time interval wherein a detected value QS of an air capacity sensor 7 and a detected value PS of a pressure sensor 14 are read in and digitally converted respectively. Then from the present detected value PB and the previously detected value PB of the pressure sensor 14, the variation in PB of a supercharging chamber 8 DELTAPB=PB-previous PB is calculated, and by multiplying this variation DELTAPB by constant KVB specified by the volume of the supercharging chamber 8, variation DELTAMB in air capacity MB in the supercharging chamber 8 is calculated. Then by subtracting the variation DELTAMB from the detected value QS of the sensor 7, passing air flow rate Qa of an aperture value 10 is calculated. Thus on the basis of change in pressure PB of the supercharging chamber 8 on the downstream of a supercharger 2, the variation DELTAMB in the air capacity of the supercharging chamber 8 is calculated, based on which the detection amount Qs of the sensor 7 is compensated thereby enabling the correct passing air flow rate Qa of the aperture valve 10 to be calculated.
