In a copper electroplating apparatus having separate anolyte and catholyte portions, the concentration of anolyte components (e.g., acid or copper salt) is controlled by providing a diluent to the recirculating anolyte. The dosing of the diluent can be controlled by the user and can follow a pre-determined schedule. For example, the schedule may specify the diluent dosing parameters, so as to prevent precipitation of copper salt in the anolyte. Thus, precipitation-induced anode passivation can be minimized.

An overload protection circuit for supplying electric power has advantageous applications especially in supplying power to capacitive loads. In prior art circuits, the charging current is lead to the capacitive load through a linearly operating transistor or through a power resistor. Therefore, prior art circuits often involve a risk of exceeding safe operating area of a power transistor, or circuits with a large number of components are needed. The present overload protection circuit has an inductor (L) coupled in series with a switching element (Q). Load current is measured (35, 38), and the switching element (Q) is controlled (35, 36) to supply current to the load via the inductor (L) until a determined current limit is achieved. After achieving the current limit the switching element (Q) is controlled to off-state, during which the freewheeling current of the inductor (L) is lead through a voltage dependent element (Z).

A vehicle gaseous fuel supply system includes a high pressure filter, a primary pressure-reducing valve, a solenoid cut-off valve, safety means, and a secondary pressure-reducing valve. A regulator is formed by disposing the high pressure filter, the solenoid cut-off valve, and the primary pressure-reducing valve on a common regulator body that has a passage providing a connection between the high pressure filter and the solenoid cut-off valve, a passage providing a connection between the solenoid cut-off valve and the primary pressure-reducing valve, and an exit passage having one end connected to the primary pressure-reducing valve.

As a result, the dimensions of the regulator formed by integrating a plurality of components can be reduced thereby lessening restrictions on the layout, and the arrangement of passages in the regulator body can be simplified thereby making the machining easy and achieving a reduction in cost.

The chain link (15) is provided with multiple recess parts (15a) and first hinge parts (21) protruding in the conveyance direction X from positions between which each of the recess parts (15a) is placed. If some object hits on an outer end of the conveyor belt (11) to apply force to the first hinge part (21), a section including the first hinge part (21) and a bulging part (30) pivots about a fulcrum at an outer base end of the first hinge part (21) to deform this section. In this invention, a point of action where force acts on the conveyor belt (11) and the center of pivotal motion of the first hinge part (21) and the bulging part (30) are determined to be spaced by a relatively short distance.

A downhole fluid flow control system (100). The downhole fluid flow control system (100) includes a flow control component (122) having an internal flow path (134) and a temporary sealing substance (136) disposed within the internal flow path (134). During installation of the downhole fluid flow control system (100) in a well, the temporary sealing substance (136) prevents fluid flow through the flow control component (122), which prevents plugging or clogging of the internal flow path (134). After installation, the temporary sealing substance (136) degrades when exposed to a water source in the well, which enables fluid flow through the flow control component (122) and thus proper operation of the fluid flow control system (100).

An object is to provide a video evaluation apparatus and video evaluation method capable of appropriately evaluating a video consisting of a plurality of frame images, using an objective standard. The object is achieved as follows. A reference characteristic, which is a predetermined spatio-temporal frequency characteristic about a video, is stored, and a video characteristic analyzer 101 calculates a spatio-temporal frequency characteristic of a target video consisting of a plurality of frame images. Then a video evaluation determiner 102 calculates an evaluated value of the target video, based on a relative relation between the calculated spatio-temporal frequency characteristic and the stored reference characteristic. This enables appropriate evaluation of the video.

Electronically steered radar systems such as frequency scanning radars are particularly suitable for detecting and monitoring slow moving, ground-based targets. So-called crawler radar systems are intended for detection of targets that deliberately attempt to avoid detection by keeping low and by moving slowly. Disclosed is a radar system which includes an electronically steered antenna and a receiver arranged to process signals received from a target located at a distance from the radar system so as to identify a Doppler frequency associated with the target. The antenna stares at, rather than glides past, the target surrounding clutter. This means that the spectral spreading of static ground clutter associated with mechanical radar systems can be eliminated, overcoming one of the shortcomings of mechanical radar systems that would otherwise render a crawler radar system unsuitable for Doppler processing.

A passenger automotive vehicle wheel bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient radial or side impact (such as a pothole or curb impact) to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and / or vibration condition in the bearing assembly. Wheel bearing assemblies according to the invention provide increased impact Brined resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.

In an electric power steering system, a vehicle reactive force model computes a correction spring reactive torque in such a manner that an elasticity component included in a steering reactive force is increased with an increase in a lateral acceleration. As the lateral acceleration increases, an increase in a basic drive torque is suppressed by a larger amount. By an amount by which the magnitude of the basic drive torque is suppressed, a target pinion angle computed by a target pinion angle computing unit decreases and a correction component for a basic assist component is decreased. A steering assist force is decreased, and a steering reactive force is increased with a decrease in the steering assist force. Thus, it is possible to obtain an appropriate steering reactive force based on the magnitude of the lateral acceleration.

A device is described for training a wild bear to be at a particular location on a regular daily schedule that matches the hunter's hours. The device provides multiple food enclosures, a scent dispenser, and a timer. The timer causes one of the food enclosures to be opened at each set interval, and dispenses a scent to signal the bear that “dinner is served”. The food enclosure which is opened will preferably only remain open for a limited time interval, for exemplary purposes one hour, so that the wild bear must be present at the scheduled time. Consequently, food is accessible only for one hour each day. The food enclosures are configured to allow a varied diet to be provided for the bear to keep him interested.
