Title: Pulse transformator
Inventor: YOSHIKAWA TETSUJI
IPC: H01F30/00
Filed: 1988-03-24
Abstract: PURPOSE:To prevent to the utmost the increase of iron loss and the generation of magnetic vibration, by making the direction of magnetic flux inverse, when the wiring bodies are driven by applied pulse voltage, the magnetic flux being generated by two kinds of winding members arranged on an iron core. CONSTITUTION:Around in iron core 11, a plurality of winding members 12, 13 are wound, which are constituted of a pair of primary windings 12a, 13a and secondary windings 12b, 13b. The first winding member 12 generates, in an iron core 11, magnetic flux in the direction shown by an arrow A, when pulse voltage is applied to the primary winding 12a. The second wiring member 13 generates, in the iron core 11, magnetic flux in the direction inverse to the arrow A, when the same polarity pulse voltage is applied to the primary winding 13a. That is, the direction of the magnetic flux formed by the winding member 12 and that of the magnetic flux formed by the winding member 13 of the other kind become inverse, so that residual magnetic flux in the core 11 caused by the magnetic flux in one direction is negated by the magnetic flux in the inverse direction. Thereby, the increase of iron loss and the generation of magnetic vibration can be restrained to the utmost.

IPC: F02B37/16
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To suppress generation of vibration of a diaphragm by closing an air bypass valve at the time of a condition in which the diaphragm is vibrated even within a prescribed time after opening the valve. SOLUTION: In the case where a throttle valve 83 is rapidly closed, pressure in second and third leading-in passages 42, 43 are a prescribed value or more, and a change rate per unit time exceeds a prescribed value; it is judged that surge noise is generated from a turbocharger 2. an ABV control valve VSV is driven so as to communicate a control port 56 of an air bypass valve 5 and a surge tank 44 with each other, and the air bypass valve 5 becomes an opening condition. The opening condition is held for a prescribed time. However when it is recognized during that period that a change rate per unit time in the second and third leading-in passages is a prescribed value and less, a condition in which a diaphragm 51 is vibrated is judged.  The ABV control valve VSV is driven so as to communicate the control port 56 of the air bypass valve 5 and the third leading-in passage 43 with each other, and the air bypass valve 5 is set to a close condition.

Inventor: SENDA SHIGERU
IPC: B29D30/62
Filed: 1984-04-10
Abstract: PURPOSE:To suppress unwanted changes, and to decrease tire deformations after extrusion and to achieve a quality stabilization with a simple method by pulling a rubber strip at such a pulling speed which is determined by a fixed number of rotations of the tire which is being formed but not affected by the extruding speed of an extruder. CONSTITUTION:A rubber strip 5 which is extruded from a mouth piece 6 of an extruder 4 is adhered to the circumference of a tire which is being formed while the strip is being pulled by the rotation of the tire 2. The pulling speed of the rubber strip 5 is such a speed as to be determined by a fixed number of rotations of the tire which is being formed and as to minimize disorderly shapes of the tire and it is controlled by a speed control device 7. The pulling speed is always kept larger than the extruding speed in order to give a constant tension to the rubber strip. In other words, the volume of the rubber strip 5 which is extruded per unit time is almost identical and, therefore, if the strip is pulled at a fixed pulling speed, an identical thickness can be achieved.
