An an actively controlled suspension system includes a fail-safe system which is associated with a pressure control valve and detective of failure of a control circuit to perform fail-safe operation. The fail-safe system operates the pressure control valve in response to failure of the control circuit, to fix the valve position corresponding to a working fluid pressure in a working chamber defined in a suspension cylinder disposed between a vehicular body and a suspension member rotatably supporting a vehicular wheel, at a pressure value at or in the vicinity of a predetermined initial or neutral pressure.

A thin-film vapor deposition apparatus has a reaction chamber for holding therein a substrate in an atmosphere isolated from an ambient atmosphere. For depositing a thin film on the substrate, the temperature of an inner wall of the reaction chamber is adjusted to control the temperature of the atmosphere in the reaction chamber, and the temperature of the substrate is also adjusted independently of the temperature of the atmosphere in the reaction chamber, while the substrate is being rotated at a high speed in the reaction chamber. Reactant gases required to deposit a thin film on the substrate are ejected from a reactant gas elector head toward the substrate in the reaction chamber. Remaining and excessive gases are discharged out of the reaction chamber.

A reactant gas ejector head enables a process gas mixture of a uniform concentration and composition to be delivered to the surface of a substrate in a stable and uniform thermodynamic state by preventing premature reactions to occur along the gas delivery route. The reactant gas ejector head comprises an ejection head body having a back plate and a nozzle plate for defining a gas mixing space therebetween. The nozzle plate has numerous gas ejection nozzles. A gas supply pipe is communicated with the ejection head body through a center region of the back plate so as to separately introduce at least two types of gaseous substances into the mixing space. Gas distribution passages are formed between the back plate and the nozzle plate in such a way as to guide the at least two types of gaseous substances from the gas supply pipe to be directed separately towards peripheral regions of the gas mixing space.

A vapor feed supply system including a vaporizer device and a method of cleaning a vapor flow region employing such a vaporizer device enables thorough cleaning of the system, without having to degrade the overall system vacuum in the process of cleaning the vaporizer device. The method includes defining a cleaning fluid passage having a predetermined withstand pressure by isolating a cleaning region of the vapor flow region, and flowing a cleaning fluid into the cleaning fluid passage under a pressure so as to enable the cleaning fluid to remain in a liquid state at a cleaning temperature of the cleaning region.

A wheeled vehicle is equipped with a feedforward steering control system which steers the vehicle through front or rear road wheels in accordance with a driver's steering input such as an angular displacement of a steering wheel, and a negative feedback system which senses a turning behavior of the vehicle such as a yaw rate or a lateral acceleration, and steers the vehicle through the front or rear wheels in such a negative direction as to reduce the turning behavior. The feedforward system may control the angular direction of the front or rear wheels in accordance with a linear combination of the steering input and the time derivative of the steering input, or may control the angular directions of both of the front and rear wheels in accordance with different transfer functions between the steering input and the front and rear wheel angles. The negative feedback system is combined with the feedforward system in various ways to provide desired characteristics of the turning behavior. The negative feedback quantity determined by the negative feedback system may be proportional to the sensed turning behavior, or may be determined in accordance with the difference between the sensed turning behavior, and the reference turning behavior calculated from the vehicle speed and steering input.

A surface treatment apparatus of a substrate can clean a substrate surface in the air without employing a vacuum apparatus, and can remove a natural oxide film or an organic material, such as BTA, from the substrate surface without resorting to plasma cleaning. The surface treatment apparatus includes: an inert gas supply section for supplying an inert gas to the whole or part of a substrate surface to form an oxygen-blocking zone; a heating section for keeping the substrate surface at a predetermined temperature; and a cleaning gas supply section for supplying a cleaning gas to the oxygen-blocking zone to clean the substrate surface.

An electrolytic processing apparatus can planarize uniformly over an entire surface of a substrate under a low pressure without any damages to the substrate. The electrolytic processing apparatus has a substrate holder configured to hold and rotate a substrate having a metal film formed on a surface of the substrate and an electrolytic processing unit configured to perform an electrolytic process on the substrate held by the substrate holder. The electrolytic processing unit has a rotatable processing electrode, a polishing pad attached to the rotatable processing electrode, and a pressing mechanism configured to press the polishing pad against the substrate. The electrolytic processing unit also has a liquid supply mechanism configured to supply an electrolytic processing liquid between the substrate and the rotatable processing electrode, a relative movement mechanism operable to move the substrate and the rotatable processing electrode relative to each other, and a power supply configured to applying a voltage between the rotatable processing electrode and the metal film of the substrate so that the rotatable processing electrode serves as a cathode and the metal film of the substrate serves as an anode.

A substrate processing method can securely form a metal film by electroless plating on an exposed surface of a base metal, such as interconnects, with increased throughput and without the formation of voids in the base metal. The substrate processing method includes: cleaning a surface of a substrate having a base metal formed in the surface with a cleaning solution comprising an aqueous solution of a carboxyl group-containing organic acid or its salt and a surfactant as an additive; bringing the surface of the substrate after the cleaning into contact with a processing solution comprising a mixture of the cleaning solution and a solution containing a catalyst metal ion, thereby applying the catalyst to the surface of the substrate; and forming a metal film by electroless plating on the catalyst-applied surface of the substrate.
