Abstract:
A fluid-pressure brake device for a vehicle includes a brake operation member, a master cylinder, wheel cylinders a fluid-pressure control actuator, a fluid-pressure control circuit, and an electric control unit. Moreover, in the fluid-pressure brake device for a vehicle, normally closed electromagnetic open/close valves are interposed on paths for connecting master system fluid-pressure circuits and a drive fluid chamber of the master cylinder with each other, the master system fluid-pressure circuits being configured to connect pressure chambers of the master cylinder and pressure chambers of the wheel cylinders—with each other. The fluid-pressure brake device for a vehicle is configured so that the electromagnetic open/close valves are opened when an action amount of the brake operation member is equal to or more than a set value. As a result, a size and a stroke of each of master pistons in the master cylinder can be reduced.
Abstract:
A brake apparatus includes: a master cylinder that forms a driving fluid pressure chamber, which drives master pistons as brake fluid is supplied and discharged; a pressure adjusting part adjusting a driving fluid pressure of the driving fluid pressure chamber; a reaction force generator that forms a reaction force chamber and that is configured to generate a reaction force fluid pressure in the reaction force chamber in accordance with an operating amount of the brake operation member; a brake fluid path, which connects the reaction force chamber to the driving fluid pressure chamber, and a valve device configured to block, at a current-on state, flowing of the brake fluid, and that communicates, at a current-off state, the reaction force chamber to the driving fluid pressure chamber through the brake fluid path to enable the flowing of the brake fluid.
Abstract:
An electro-optic device includes a pixel section and a terminal section through which a semiconductor circuit or a wiring board is mounted around the pixel section. The terminal section has a multilayer structure including a terminal connection wire including an uppermost layer containing titanium, a terminal interlayer made of an electroconductive material capable of being wet-etched, and a terminal transparent electroconductive film in that order from below.
Abstract:
A brake device includes: a mechanical pressure regulating part having a high-pressure port, a low-pressure port, a pilot pressure input port, and an output port which outputs fluid pressure corresponding to the pressure supplied to the pilot pressure input port by fluid pressures supplied to both of the high- and low-pressure ports, to a chamber for a master piston; a high-pressure source connected to the high-pressure port and the pilot pressure input port; a low-pressure source connected to the low-pressure port and the pilot pressure input port; and an electrically-operated pilot pressure generating part which includes control valves for controlling flows of the brake fluid between the high-pressure source and the pilot pressure input port, and between the low-pressure source and the pilot pressure input port, respectively, and which outputs desired fluid pressure to the pilot pressure input port by controlling flow of the brake fluid with control valves.
