  • Publication number: 20200308749
    Abstract: According to the present invention, it is appropriately determined whether there is a portent of abnormal vibration or not, and an appropriate control is conducted such that no abnormal vibration occurs during a dewatering stroke. A control unit comprises a calculation unit, a determination unit, and a motor rotation control unit. The calculation unit calculates the rate of change in water level, which indicates the amount of change in water level per a predetermined period of time, on the basis of the result of sensing by a water level sensor in connection with a water supply stroke. The determination unit determines whether laundry having a waterproof property is contained in a drum or not on the basis of the rate of change in water level during the water supply stroke calculated by the calculation unit.

  • Publication number: 20200308751
    Abstract: A washing machine includes a drum accommodating laundry, a motor configured to rotate the drum, a speed sensor configured to detect a rotational speed of the drum, and a processor. The processor configured to: determine a mass of the laundry corresponding to each of a first acceleration section and a second acceleration section based on the rotational speed detected by the speed sensor, and control the motor such that an absolute value of the rotational speed at a start time of the first acceleration section is substantially the same as an absolute value of a rotational speed at a start time of the second acceleration section. A rotational direction of the drum corresponding to the rotational speed at the start time of the first acceleration section is opposite to a rotational direction of the drum corresponding to the rotational speed at the start time of the second acceleration section.

  • Patent number: 6453217
    Abstract: A frequency switching method controlled by a microcomputer (74) incorporated in a frequency switching device is capable of halting a timer (81) at a timing at which a pattern of levels of pulse signals supplied from the timer (81) is agreed with a predetermined pattern, of setting a desired frequency to the timer (81), and then of restarting the operation of the timer (81) after a passage of a predetermined time period counted from the above timing in order to generate pulse signals of a desired frequency and outputs them to a pre-driver (73).

  • Patent number: 6304465
    Abstract: A power regulator including a coil connected to an output of a DC power source for rectifying an AC voltage, a charge-and-discharge capacitor for charging a current supplied from the DC power source through the coil and a backflow preventing diode, a switching device connected to a connection point of the coil and backflow preventing diode in parallel with the DC power source, and a microcomputer for detecting a zero-cross point of the magnetic field energy generated in the coil or the current flowing through the coil, and for bringing the switching device into conduction in response to the detection of the zero-cross point. This makes it possible to solve a problem of a conventional device in that the switching period of the switching device cannot be changed in accordance with variables such as temperature change, errors in circuit constants and the like because switching periods of the switching device are predetermined values.

  • Patent number: 6215501
    Abstract: For a polygon without self-intersection, with one of line segments constituting the outline of the polygon selected sequentially in the counterclockwise rotation, all the bits in the right direction of the selected line segment on the horizontal coordinate, inclusive of those for the selected line segment, on the plane work area (1 bit/pixel) of the work memory are inverted to draw (Step S22). Subsequently, only some of the line segments constituting the outline of the polygon whose vectors are in the upward direction (which makes an upward vertical-coordinate variation) are further drawn on the work memory (2A) (Step S23). Finally, the drawing information is transferred with extension from the work memory to the display memory (Step S24). Having the above steps, a method for achieving proper filling of a polygon with a decrease in load on a processor is provided.

  • Patent number: 5808598
    Abstract: To obtain a display method navigation map intended to lessen the load of control means such as CPU, by quick scroll display. By comparison between preceding judging region (JO) and present judging region (JN), a changing direction of judging region is recognized, and rewriting is processed in advance in a page (display off divided memory region) of a map memory, being out of map display region of a display device. At this time, rewriting is processed by priority in a divided memory region that is high in possibility of move of the own vehicle and that must be written at the earliest opportunity.
