Title: Method of controlling solid fuel combustion equipment
Inventor: ODA YOSHIAKI
IPC: F23K3/14
Filed: 1984-04-18
Abstract: PURPOSE:To make an igniting operation unnecessary even under a condition that combustion heat is not needed is continued for a long time, by intermittently feeding only solid fuel into a combustion chamber when combustion is taken place under the above-mentioned condition. CONSTITUTION:When a sensor 36 senses a condition that combustion heat is needed in a solid fuel combustion equipment, a controller 34 actuates both motor 16 and blower 24 to start to replenish both solid fuel and combustion air into a combustion chamber 10. Because intermittent operation of a motor 16 always keeps some half-burned fuel in the combustion chamber, newly replenished solid fuel can be ignited by heat of solid fuel which is continuously burning in the combustion chamber. With such an arrangement, an igniting operation is not necessary even under a condition that combustion heat is not necessary is continued for a long time in the titled solid fuel combustion equipment.

Title: Washing machine
IPC: D06F33/02
Filed: 1992-03-31
Abstract: PURPOSE:To properly detect a feed water level in a washing tub or a spin basket by causing the spin basket to rotate under the supply of water thereto, and detecting the feed water level on the basis of load torque detected with a load torque detecting means. CONSTITUTION:A spin basket 3 is caused to rotate at a constant speed under the supply of water thereto, and a load torque change due to a water level rise is detected. When the torque reaches the predetermined level corresponding to a final water level, the supply of water is stopped, and water is supplied up to a final washing level. In this case, the on-duty ratio of a PWM signal fed to a brushless DC motor 5 or inverter current may be detected, instead of detecting the load torque. Also, motor startup torque necessary to start the spin basket 3 under the supply of water may be detected at every constant time to detect a water level from a change in the startup torque. Or, a water level may be detected from a change in the speed of the motor 5, with constant voltage applied at all times and water supplied under the rotation of the spin basket 3.

The aramid fibers having the high heat resistance are effective as heat resistant blanks. More particularly, a meta type arom. polyamide (metaphenylene isophthalamide) is suitable as irregular section yarn. The aramid fibers are capable of forming the web together with the other fibers. A polyethylene terephthalate, etc., are usable as the other fibers.

Abstract: PURPOSE:To prevent an OFF signal from affecting an ON signal for a gain controlling circuit, by changing the gain in accordance with the amplitude of mixed key pulse and then controlling the part where the super signal is inserted to a main line signal. CONSTITUTION:Gate circuits 15 and 16 receive the voltage generated at a logical circuit 17 based on ON or OFF effect controlling information to the super signals S1 and S2 which are applied to terminals 5 and 6. Then the circuits 15 and 16 gate the 1st and 2nd super signals with the 2nd and 1st key pulses K2 and K1, respectively. When the control voltage of the terminal 5 turns on and the 2nd control voltage of the terminal 6 turns off, the super signal 2 is gated through the circuit 16 and by the pulse K1 to perform the control so that the super signal DS2 does not emerge at the output of the circuit 16 during the period of the pulse K1. As a result, the waveform is shown like MS' when the super signal is inserted. Thus the signal which is off does not emerge at the fringed part.
