Title: Operation control method for fully automatic washing machine
Inventor: YAMAMOTO HIROYUKI
IPC: D06F33/02
Filed: 1990-06-06
Abstract: PURPOSE:To reduce a brake operating sound in the case of braking by automatically setting time just after the OFF of dehydration to the brake operation corresponding to the quantity of cloth based on the information of a cloth quantity sensing process. CONSTITUTION:In the cloth quantity sensing process, the inverse stirring of ON for 0.5 sec. and OFF for 1 sec. is executed and the inverse electromotive force of a motor 8 when rotating a rotary object 6 by inertia in the case of FF is detected by the terminal voltage of a capacitor 8a for driving the motor 8 and converted to a direct current rectangular wave pulse. Then, the quantity of cloth is decided by measuring time t1 during this pulse. Corresponding to the washing amount, the water level, water current and time are automatically set and the dehydration is started after completing washing and rinsing. After sufficiently dehydrating water contained in laundry, the energizing of the motor 8 is stopped and the following brake operation is executed. For example, when the quantity of laundry is 4.0kg, the time for the brake operation is set to 50 sec. after stopping the inertia rotation of a washing and dehydrating tub based on the quantity of laundry. In the case of the brake operation, a dehydration tub 5 is stopped and the sound to be generated is only the sound of returning a solenoid 7a.

Title: Method for checking program run for controlling engine
Inventor: YOSHIHARA MASAHARU
IPC: G06F11/36
Filed: 1982-08-26
Abstract: PURPOSE:To detect a defective place easily and to improve reliability by forming a travelling flag and previously set up bit pattern in each job by an interruption processing program to be executed synchronously with the revolution of an engine or time. CONSTITUTION:Bits BITphi-BIT7 are formed in PROG.CHK (travelling flag) and time interruption (2ms, 10ms, 100ms), angle interruption, ignition interruption, and other respective processing are made correspond to respective bits. If an interruption is generated during background program processing, the program jumps to the interruption and the check bit corresponding to the interruption is turned to ''1''. The contents of the program check are compared with the bit pattern previously set up. Since the checking bit patterns of the engine are different at the stop and operation time respectively, the bit patten should be switched in accordance with each interruption. After the switching, data for the pattern are processed.

IPC: G03C1/015
Filed: 1986-06-25
Abstract: PURPOSE:To improve a melting speed by executing the stirring in a melting tank at two points; the central part of the tank and the point along the melt taking-out surface in the bottom of the tank and separating and discharging a gel-like material and melt by means of a net, etc., around the melt taking-out outlet in the bottom of the tank. CONSTITUTION:The stirring device 6 has two kinds of stirring vanes; central stirring vane and lower stirring vanes 8. The central stirring vane 7 is a paddle- shaped vane and the lower stirring vanes 8 are 4 pieces of semi-arc-shaped paddle-type vanes.
