IPC: H02P27/02
Filed: 1986-12-18
Abstract: PURPOSE:To easily control power and prevent noise from being generated, by thinning-out-controlling commercial power voltage with a zero-cross trigger. CONSTITUTION:From a zero volt pulse generating circuit 3, pulse train synchronized with the zero-cross point of a commercial power source is generated. A voltage detector 4 is used to detect the voltage across a bidirectional thyristor 2. A comparator 5 compares the output of the voltage detector 4 with a reference voltage 6, and the output of the comparator 5 is directed to one side for input at the input terminal of a NAND gate 7. The output of the zero volt pulse generating circuit 3 is applied to the other side of the input terminal. When the input of a motor fan 1 is heightened, then the output of the voltage detector 4 is lowered, and when the output comes to the value of the reference voltage 6 or less, then the output of the comparator 5 gets lower and the output of the NAND gate 7 gets higher, and the bidirectional thyristor 2 is turned OFF. In other words, to the motor fan 1, the voltage of thinned-out commercial power voltage is applied and controlled.

Filed: 1990-11-06
Abstract: PURPOSE:To switch an ECL compatible operation to a CMOS level operation by a control signal by controlling the continuity of plural output transistors according to a control input impressed to a control input terminal, and outputting different output logical levels. CONSTITUTION:This circuit is equipped with at least one control input terminal EN, and plural output transistors MP1, MN1, and MN2. Then, the continuity of plural output transistors MP1, MN1, and MN2 is controlled according to the control input impressed to the control input terminal EN, and the different output logical levels are outputted. That is, when the control input EN is in a low level, the transistor MN2 is turned off, so that this circuit can be equivalent to the output buffer of an open drain constitution by the transistor MP1 when viewed from an output terminal OUT, and an interface equivalent to an ECL compatible output buffer can be obtained. And also, when the control input En is in a high level, the output transistors MP1, MN1, and MN2 are operated as the buffers which output normal CMOS logical levels. Thus, this circuit can be operated as both the CMOS level buffer and the ECL compatible buffer by the control of the control signal EN.

Filed: 1994-11-10
Abstract: PURPOSE: To measure the amount of abrasion in a short time by sliding a scale holding tool on the groove part, which is equal to the width of a wheel flange, provided at the central part of a substrate having the same shape and size as those of a new item, and measuring the abrasing amount of the entire wheel tread. CONSTITUTION: A substrate 1 is applied on a tread 11 of a wheel to be measured. At this time, a substrate-deflection preventing plate 4 is brought to tight contact with a wheel flange 10, a scale holding tool 3 is slidden to the measruing position of the tread 11 and a scale 6 is applied on the tread 11. The read-out value of the scale 6 on the lower side of a piano wire 7 at the abrasion-amount reading position of the tread 11 is the amount of the abrasion of the tread. If the flange 10 is abraded or inclined, the scale holding tool 3 is slidden to the right end of the substrate 1, and the holding tool 3 is turned by 180 degrees. With the flange 10 on the opposite side as the reference, the amount of abrasion is measured on the opposite side of the substrate 1 by the same way.  Even for the abrasion of the flange 10, the gap between the substrate 1 and the flange 10 can be simply measured by using the holding tool 3.
