Inventor: MORIKAWA MASATOSHI
IPC: H02P6/08
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To slowly reduce the current in a first phase driving coil and thus reduce noise by, even after the first transistor in a second half-bridge circuit is made to form its current path, making the first transistor in a first half-bridge circuit interrupt, form and re-interrupt its current path. SOLUTION: When the energized phase of a three-phase bridge circuit is switched, an upper arm switching element 25 in phase V that switches from the unenergized phase to the energized phase, for example, is kept energized, and further an upper arm switching element 23 in phase U that switches from the energized phase to the unenergized phase is turned on and off according to any duration of energization. Meanwhile, a lower arm switching element 28 in phase W is PWM-controlled. Thus phases U, V and W are sequentially subjected to sustained energization, PWM control and energization duration control, and soft switching is thereby accomplished to make gentle the rise and fall of the phase currents when the energized phase is switched. This makes it possible to reduce noises from a sensorless brushless motor.

Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce a temperature detecting error of a temperature sensor due to noise and detect an absolute temperature of a head even when the head is replaced, by a method wherein an alarming signal is outputted when a temperature, detected by a means for detecting a temperature near a nozzle, has reached a set temperature or higher. SOLUTION: When a temperature of a recording head is detected by a temperature sensor 3, a voltage at both terminals of the temperature sensor 3 is subjected to offset correction and amplification by a converting amplifier, constituted of resistors R1 , R2 , R4 , a constant current source I2 and an operational amplifier A1 , and thereafter, is inputted into a comparing means or a comparator A2 . When the detected temperature is a predetermined value or higher, the output of the comparator A2 becomes a low level and a heater driving signal is masked by an AND gate G1 . Then, when the output of the comparator A2 has become a high level, an alarm signal or an alarm is generated. The fluctuation of the measurement of an absolute temperature can be corrected by changing the offset and gain of the converting amplifier.

Filed: 1988-07-27
Abstract: PURPOSE:To minimize the grade-down ratio caused by alumina-kind defect, powder-kind defect, etc., in the finished product without nozzle clogging by blowing the specific rate of Ar in accordance with casting speed of molten steel. CONSTITUTION:In continuous casting for the molten steel in steel-making plant, the reduction of the alumina defect is obtd. caused by effect of floating-up and removal of inclusion with Ar blowing and on the other hand, the powder- kind defect is developed caused by enclosure of the powder with unsettled meniscus. In any case, in the case of using Ar, the optimum blowing rate must consider at the same time of the effect of the prevention to nozzle clogging. For this purpose, this is made to 3.0-5.0l/ton in accordance with the prescribed casting speed. Besides this, the casting speed is influenced to the grade-down rate of the product. The quicker the casting speed is, the higher the grade-down rate is. Therefore, it is necessary to decide the optimum blowing rate in the range of 3.0-5.0l/ton under combinating with various kinds of factors. By this method, the grade-down rate can be made to the min. without any clogging the upper nozzle or submerged nozzle.
