Abstract: PURPOSE:To detect a load quantity bearing on a motor, exactly, and enable the quantity of laundry to be correctly grasped by rotating a drum in the directions of forward rotation and reverse rotation at the time of operation, to detect the solution level of the drum with a solution level detecting means, and by computing an average motor current value with a motor current value computing means. CONSTITUTION:Between an external tank 9 and a drain valve 18, an air trap 20 is set, and by a pressure sensor 21, a solution (water) level in the external tank 9 is detected through pressure. On the discrimination of a load quantity, after feeding water, till a water level comes to 3 degrees (water level of 3/10 in the case of drum diameter divided equally into 10), the drum is operated with previously set rotational frequency and reverse rotation period, and after the water level comes to 3 degrees, the rotational frequency of the drum 12 is turned into 8-15rpm, and the reverse rotation period is turned ON for 3 seconds and is turned OFF for 3 seconds. After that it is turned ON every time the drum 12 is rotated forward and reversely and after that, the lapse of 2 seconds for a motor current value to be almost stabilized is checked, and a value after the lapse of 2 seconds is converted to the voltage of 0 volt (stop)-10 volts (rating time) and is read in a micro-computer. In order to eliminate the influence of the ununiformity of data, the process is repeated ten times, and by averaging, data according to motor current is obtained.

Filed: 1990-11-02
Abstract: PURPOSE:To add a pulse signal whose amplitude is stable to an information signal by providing a resistor between an emitter of a 1st transistor(TR) and a base of a 2nd TR and always supplying a current from a current source to the 1st TR regardless of the state of a switch controlling the supply of the current from the current source to the resistor. CONSTITUTION:A TR Q2 is turned on and a TR Q3.is turned off for a period A and a current I is supplied to the TR Q2 from the emitter of the TR Q1 not through a resistor R. Moreover, the TR Q2 is turned off and the TR Q3 is turned on for a period B and the current I is supplied to the TR Q2 from the emitter of the TR Q1 through a resistor R. Thus, the current flowing to the emitter of the TR Q1 is Io+I for both the periods A, B and since no fluctuation in a base-emitter voltage VBE of the TR Q1 is caused, a burst pulse whose amplitude is stable is added to a color difference signal.

Title: Plowing depth controller for tractor
Inventor: DOI YOSHINORI
IPC: A01B63/114
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To provide the subject controller which prevents the working machine from moving upward unnecessarily and thereby prevents plowing depth in the field from changing excessively by greatly changing, for a given time, a dead zone range on the machine-rising side after the plowing depth reading is out of the dead zone and the working machine is moved upward. SOLUTION: This controller is for a tractor equipped with a working machine connected in such a way as to freely move upward and downward, plowing depth setting means which sets a plowing depth for the working machine, and plowing depth sensing means which senses depth to which the working machine plows, wherein the working machine is controlled in such a way that sensed depth to which it plows is kept within dead zones A, provided on the upper and lower sides of the depth set by the depth setting means. When the working machine is moved upward to such an extent as to cause the sensed depth to go out of the dead zone A on the machine-rising side, range of the dead zone A is greatly changed for a give time. This controls upward motion of the working machine, when conditions of the tractor is greatly changed, thereby preventing plowing depth from changing unnecessarily.
