摘要:
In a brake control apparatus (20) that controls braking forces which are applied to wheels based on the pressure of a brake fluid, when a hydraulic pressure actuator (40) controls the hydraulic pressure that is transferred to wheel cylinders (23) using the hydraulic pressure of the brake fluid in a power hydraulic pressure source (30), a brake ECU (70) closes a simulator cut valve (68) if the pressure of the brake fluid in the power hydraulic pressure source (30) falls below a predetermined value (Pssc) or if it is determined that the number of times the brake operation member (24) is operated within a predetermined value. In addition, the ECU (70) may change the timing for closing the simulator cut valve (68) based on the road surface condition estimated at the time of antilock control start. Thus, a driver is less likely to feel unusual brake feel when a braking control mode is changed.

A brake control system has a manual fluid pressure source and a power fluid pressure source. A fluid pressure actuator forms an X-pipe having a first channel and a second channel. The power fluid pressure source supplies the operating fluid to each wheel by using the first channel and the second channel. A channel system including the first channel and a channel system including the second channel can be isolated from each other by an isolation valve. The fluid pressure actuator includes a regulation unit configured to regulate a state of supplying the operating fluid such that a difference between a state occurring when the operating fluid is supplied to one of the first channel and the second channel after passing through the isolation valve, and a state occurring when the operating fluid is supplied to the other channel without passing through the isolation valve, is reduced.

At a contact step in a tool radius adjusting method, a reference portion of a movable body provided radially movably on a housing of a boring tool and a position adjusting reference member fixed on a machine tool are brought into contact by sliding the movable body relative to the housing so that the position of a cutting blade comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade relative to the rotational axis is adjusted by changing the relative position between a tool spindle holding the boring tool and the position adjusting reference member in a direction to come close to each other by drive mechanisms of the machine tool used for positioning a spindle head with the tool spindle relative to a workpiece in machining the workpiece with the cutting blade.

Provided is a safe and efficient method for producing lithium metal which facilitates efficient production of anhydrous lithium chloride without corrosion of the system materials by chlorine gas or molten lithium carbonate, and which allows production of lithium metal by molten salt electrolysis of the produced anhydrous lithium chloride as a raw material. The method includes the steps of (A) contacting and reacting lithium carbonate and chlorine gas in a dry process to produce anhydrous lithium chloride, and (B) subjecting the raw material for electrolysis containing the anhydrous lithium chloride to molten salt electrolysis under such conditions as to produce lithium metal, wherein the chlorine gas generated by the molten salt electrolysis in step (B) is used as the chlorine gas in step (A) to continuously perform steps (A) and (B).

In a brake controlling device (20), a separating valve (60) is provided in a main flow path (45) for interconnecting a first liquid pressure circuit and a second liquid pressure circuit. When an abnormality detecting section detects an abnormality relating to brake fluid pressure, a controlling section sets the separating valve (60) to a closed state. A leakage suppressing section performs leakage suppressing processing for suppressing entry of a brake fluid, which is in the first liquid pressure circuit, into the second liquid pressure circuit after the separating valve (60) is set to the closed state. A leakage suppressing section sets a master cut valve (64) to a closed state to perform the leakage suppressing processing.

Methods and devices for forming a vertically-oriented multilayer laminates, for example, a vertically-oriented multilayer laminates, are provided. The laminates may be fabricated by hardenable fluids, for example, polymers that are directed along flow paths to divide, repossession, and combine streams to provide the desired laminated structure. The flow divisions and recombination may be practiced repeatedly wherein laminates have tens or even tens of thousands of individual layers may be produced. The polymers used may have comparable viscosities, for example, having viscosity ratios of less than 3. Though aspects of the invention may be used packaging, aspects of the invention may be applied to any field where laminated structures are desired.
