Filed: 1991-01-19
Abstract: PURPOSE:To prevent any wet compressed air flowing backward to a dryer from flowing into a crankcase from a supply-exhaust passage via an interconnecting passage at the time of exhausting from an air compressor. CONSTITUTION:When an exciting coil 28 is fed out of a control unit and magnetized at the time of exhaust of an air compressor for an air suspension or the like, a plunger 30 is attracted to a core 33 together with a rod 36 against spring force of a valve spring 32. With this, one side valve part 31 constituting an exhaust valve 24 separates from one side valve seat of a one side connecting part 29 and is opened, and it interconnects an interval between a discharge chamber 19 and a supply-exhaust passage 20, while an other side valve part 37 constituting a cutoff valve 34 takes an other side valve seat of an other side connecting part 35 and is opened, and it interrupts an interval between an interconnecting tube 21 and the supply-exhaust passage 20. Then, wet compressed air flowing in an arrow B direction to a dryer 22 from the air compressor is exhausted to the outside from a supply-exhaust port 20D of the passage 20 via the discharge chamber 19, the one side connecting part 29 and the supply- exhaust passage 20.

Title: Electromagnetic detector for rotation position
Inventor: KATOU TSUNEO
IPC: G01D5/245
Filed: 1982-02-09
Abstract: PURPOSE:To enable preventing of the occurrence of a mulfunction due to an interference magnetic flux through a simple constitution, by a method wherein a magnetic interference noise  produced due to an interference magnetic flux flowing from one end to other end of an electromagnetic pickup is produced by a weight relation in practice, and is prevented from appearing for a period other than a signal generating period. CONSTITUTION:After, when, with the rotation of a driving shaft 2, large radius outer periphery  D1 of a rotor 1' starts to approach a stator 3', a magnetic flux phi2 begins to increase and  attains a maximum value, a constant value is maintained for a while. If a small radius outer  periphery D2 starts to approach the stator 3', the magnetic flux phi2 begins to decrease, and  thereby the magnetic flux phi2 changes in a manner to form a trapezoid-shaped waveform toward the large radius outer periphery D1. Thus, in case, with the rotation of the shaft 2, the  large radius outer periphery D1 of the rotor 1' approaches the stator 3', an interference magnetic flux in a reverse direction to that of a magnetic flux phi1 of a main magnetic flux loop F1 starts to flow by means of an interference magnetic flux loop FD and attains a constant value, and in case the periphery D1 parts from the stator 3', said interference also decreases in a  direction of zero. Thus, against the magnetic flux phi1 an interference magnetic flux in a trapezoid-shaped waveform flows to a pickup coil 4. A necessary adjustment is made through  formation of the large periphery D1 and the small periphery D2 on a signal rotor 1'.

Filed: 1979-02-22
Abstract: PURPOSE: To efficiently and accurately true a borazon grinding stone while keeping the shape of the borazon grinding stone and an alumina grinding stone and preventing the wear of a diamond rotary dresser.  
     CONSTITUTION: A cylinder 13 feeds a diamond rotary dresser 10 to the working surface of a borazon grinding stone 1 at a fixed feed rate, while a cylinder 14 presses a square alumina grinding stone 11 against the working surface of the borazon  grinding stone 1 at a fixed pressure to remove the binder. The rotary diamond  dresser 10 grinds off the abrasive particles from the working surface of the borazon  grinding stone 1 thus truing the borazon grinding stone 1. The dresser 10 is subjected to a lower truing resistance as the binder is removed by the square alumina  grinding stone 11 so that the wear of the dresser 10 and spoiling of the shape of  the borazon grinding stone 1 by the alumina grinding stone 11 are reduced. Thus  truing and dressing are performed at the same time without spoiling the shape of  the borazon grinding stone 1.
