An implantable device, such as an infuser device for bidirectional hydraulically controlling a medical artificial sphincter, enhances power transfer characteristics to a secondary coil thereby allowing implantation to greater physical depths and / or enclosing the secondary coil within a housing of the infuser device. The enhanced power transfer is achieved with multiple coils that are longitudinally aligned and physical and electrical parallel to form the secondary loop of a transcutaneous energy transfer system (TET) instead of a single coil. It better optimizes the power transfer from a parallel tuned tank circuit primary coil to an implanted secondary series tuned tank circuit coil.

The computer of the present invention is provided with a main body on which keys to be operated by the user are disposed and a display unit that displays an image in accordance with each operation executed for the main body. Each key disposed on the main body is composed of its body having a key top and a light accumulator recess opened in the key top. The light accumulator recess is formed in a manner indicative of the character or symbol associated with such key. The light accumulator recess has embedded in it a light accumulating material such that the character or symbol associated with the key is illuminated by the residual light emission of the light accumulating material when the computer is operated in a location with little or no ambient light.

A substrate holder includes a base; a first holding portion which is formed on the base and which attracts and holds a substrate; and a second holding portion which is formed on the base and which attracts and holds a plate member in the vicinity of the substrate attracted and held by the first holding portion. In an exposure apparatus including such a substrate holder, the plate can be exchanged easily, thereby making the maintenance of the apparatus easy. Consequently, such an exposure apparatus is suitable for immersion exposure.

A part of exposure beam through a liquid via a projection optical system enters a light-transmitting section, enters an optical member without passing through gas, and is focused. The exposure apparatus receives the exposure light from the projection optical system to perform various measurements even if the numerical aperture of the projection optical system increases.

An imaging lens includes a first lens group having positive refractive power; a second lens group having positive refractive power; and a third lens group having negative refractive power, arranged in this order from an object side to an image plane side. The first lens group includes a first lens having positive refractive power, a second lens having negative refractive power, and a third lens having negative refractive power. The second lens group includes a fourth lens and a fifth lens. The third lens group includes a sixth lens and a seventh lens. The first to third lenses have specific Abbe's numbers.

An evaporated fuel treatment apparatus is provided for reducing a refilling time, ensuring satisfactory adsorption / desorption performance for an evaporated fuel, and reducing the manufacturing cost through a simplified structure. The evaporated fuel treatment apparatus comprises a casing having formed therein a first chamber in communication with the fuel tank, a second chamber in communication with the first chamber, and a third chamber in communication with the second chamber and the atmosphere. Active carbons are contained in the first chamber and second chamber for adsorbing fuel components in an evaporated fuel introduced from the fuel tank. An adsorbent is contained in the third sub-chamber for adsorbing fuel components in the evaporated fuel introduced from the second chamber. The adsorbent has an air-flow resistance which is set smaller than that of the active carbons.

The outer conductor is comprised of a first outer conductor (3) and a second outer conductor (4). The first outer conductor (3) and the second outer conductor (4) are connected to each other by attaching them to an insulating housing (1) and contacting the contact section (48) of the second outer conductor (4) to the first outer conductor (1). The backsides of the switching terminal (20) and the connecting terminal (21) are covered by a backside shielding section (43), and the lead section provided on the backside shielding section (43) is arranged between the lead section (20B) of the switching terminal (20) and the lead section (21B) of the connecting terminal (21).

An electrode with three-dimensional capabilities for detection and control of brain state changes of a subject. The electrode includes a disk portion having an upper surface and a lower surface, and a shaft portion secured to and extending perpendicularly outwardly from the lower surface of the disk portion; the shaft portion having an outer surface. The disk portion and shaft portion may include one or more recording or stimulating contact surfaces structured to operatively interact with the brain of a subject. Insulating material isolates each of the recording or stimulating contact surfaces from each other. At least one conductor operatively and separately connect each of the recording or stimulating contact surfaces in communication with external apparatus. The disk portion and shaft portion are structured relative to each other to operatively provide support and anchoring for each other while providing three-dimensional capabilities for detection and control of brain state changes of a subject. Modified embodiments include insertible / retractable electrode wires, both contained in channels and sheathed in axially displaceable cannulae; activating mechanisms for inserting / retracting the electrode wires and / or cannulae; and multiple shaft portions.

Filter systems that are effective against a broad range of contaminants including HCN, cyanogen chloride (CK), acid contaminants and basic contaminants such as ammonia without the need (but with the option, if desired) for using molybdenum or chromium containing materials. The filtering systems of the present invention include a tungsten-based material and other impregnants incorporated into a substrate such as filter media particles.
