Title: Washing machine
Inventor: YAMAMOTO TAKAHARU
IPC: D06F37/42
Filed: 1989-10-30
Abstract: PURPOSE:To make abnormal rocking of a tank detectable without taking the trouble for assembly by providing a sensor for generating an aerial propagation signal to a reflecting part and outputting a distance detecting signal in accordance with reflection of the aerial propagation signal, when a tank is in rotation. CONSTITUTION:When water is supplied into a rotary tank 9 from a supply water valve 22, in a control unit 18, a motor 2 is started by short time-electrification through a triode AC switch (TRIAC) 24, and by coasting power of the motor, the rotary tank 9 is rotated at a low speed followed by a reflecting part 17. Next by reflecting an ultrasonic wave generated from a sensor 16, a distance detecting signal, output from this sensor 16, is read to measure a distance X to a reflecting part of the signal, thereafter a difference Z from a distance Y, measured in the preceding time, is calculated. Whether a calculated value is sufficiently large or not is judged. Thus by enabling a degree of rocking of the rotary tank 9 to be calculated and determined based on the transmission signal to the reflecting part 17 of the ultrasonic wave and the distance detecting signal by reflection from the reflecting part 17, by the sensor 16, during the time the rotary tank 9 makes one turn, the trouble for assembly is not required as it is different from that of mechanical detection by a mechanism formed of lever, microswitch, etc.

Filed: 1993-11-11
Abstract: PURPOSE:To increase characteristic impedance by forming two grounded conductors using thick film wires whose conductor thickness is larger than the width and a center conductor apart from a board by a predetermined interval between the grounded conductors onto the board. CONSTITUTION:Grounded conductors 2, 3 are formed on a board 1. Furthermore, a center conductor 4 whose width is W and whose thickness is (ts) is formed on the board 1 between the conductors 2, 3 while being floated by a height (h) from the surface of the board. Moreover, a gap (g) is provided between the conductors 2, 3 and the conductor 4. Then the circumference of conductors 2, 3, 4 are covered by a dielectric film. When a high frequency signal is inputted to the high frequency line of the configuration as above, an electromagnetic field is produced between the conductor 4 and the ground conductors 2, 3 and the electromagnetic wave is propagated in the lengthwise direction of the conductor 4. Thus, the opposed area between the conductors 2, 3 and the conductor 4 is decreased and then the floating capacitance between them is reduced, resulting that a time constant (tau) of the line is reduced.
