Abstract: In a solenoid of a hydraulic pressure control apparatus, a region adjacent to an oil flow guide portion of a stopper breathing passage is formed in a magnetism application region, through which a leakage magnetic flux leaking from a magnetic circuit at a time of turning on of a coil passes. Thereby, magnetic foreign objects made of iron or iron containing material are magnetically attracted to the leakage magnetic flux, so that intrusion of the foreign objects from an outside of the solenoid into a second volume variable chamber through the stopper breathing passage is limited.

Abstract: According to an embodiment, a decoloring device is disclosed. A decoloring unit decolors an image formed with decolorable colorant on a sheet. A reading unit reads a surface of the sheet to determine whether the surface of the sheet is reusable. When the surface of the sheet read by the reading unit is determined to be not reusable, a marking unit adds a mark to the read surface. A first tray receives the sheet on which a mark is added by the marking unit.

Abstract: A solenoid device includes a plunger driven in an axial direction, a wall portion arranged to oppose the plunger in the axial direction, and a respiratory pore cover covering an opening of a respiratory pore of the wall portion. A volume variable chamber is defined between the plunger and the wall portion. The respiratory pore cover defines a communication space communicated to the respiratory pore, and an opening which causes the communication space to communicate with an exterior space. A volume of the communication space is larger than a predetermined volume of fluid that flows through the respiratory pore from or into the volume variable chamber by a predetermined movement of the plunger.
