Abstract: Providing a holding device which can hold a plurality of types of workpieces and can reliably prevent a liquid in a liquid tank from leaking. The holding device includes a holding member configured to hold an article (workpiece) to be plated in a holding chamber. The article is disposed over a liquid tank in which a plating solution (liquid) flows and the holding chamber communicating with the liquid tank. The holding member has a plurality of abutting parts which closely abut against portions of an outer periphery of the article at a same level thereby to hold the article therebetween. The abutting parts are formed of a sponge sheet (elastic body) with chemical resistance. The holding device includes a pressurizing unit configured to supply air into the holding chamber to pressurize an atmosphere in the holding chamber while the article is held by the holding member.

Abstract: A damper includes a cylinder, an annular rod guide, an annular seat, a rod, an annular oil seal, a rebound cushion, and a communication passage. The cylinder houses an action chamber. The rod guide is secured to one side opening of the cylinder. The seat is secured to the rod guide. The rod is inserted through inner peripheral sides of the rod guide and the seat. The oil seal is held to an inner periphery of the rod guide and slidably in contact with an outer peripheral surface of the rod. The rebound cushion bumps against the seat. The communication passage transmits a pressure in the action chamber to the oil seal. An opening on the communication passage on the action chamber side is disposed on an outer peripheral side relative to a part of the seat against which the rebound cushion bumps.

Abstract: There is provided a damper control device and a suspension apparatus that are capable of effectively preventing a posture change such as pitching or rolling of the body of a vehicle. To achieve the above object, a damper control device of the present invention is designed to control a damping force of a damper in accordance with a rate of change in acceleration or a rate of change in angular acceleration. If there is a time delay in the rising of the acceleration acting on the vehicle body with respect to the driving operation being performed by the driver of the vehicle, the rate of change in the acceleration has a phase lead relative to the acceleration, and accordingly, the rate of change has only a short time delay with respect to the driving operation.

Abstract: A pump device includes: a main pump and a sub pump; and a switching valve that switches so as to supply the hydraulic oil discharged from the sub pump to the hydraulic device, or to return the hydraulic oil discharged from the sub pump to the suction side. The main pump and the sub pump each include: a rotor, a discharge port into which the hydraulic oil discharged from a pump chamber is led, and a groove-shaped discharge-side notch formed from an opening edge of the discharge port toward a direction opposite to a rotation direction of the rotor. The switching valve switches according to a rotation speed of the drive shaft. At least one discharge-side notch of the sub pump is formed so that a resistance applied to the flow of the hydraulic oil passing therethrough is greater than that of the discharge-side notch of the main pump.
