Method and apparatus for producing hollow rack bar and mandrel used for rack bar production

A system for forging a rack bar from a blank pipe. A blank pipe 1 is held between dies 2 and 3. Stockers 7L and 7R are arranged on respective sides of the die set. In the stockers 7L and 7R, left-handed shuttles 6L1, 6L2, 6L3, . . . 6Ln and right-handed shuttles 6R1, 6R2, 6R3 . . . 6Rn are stored. First, a left-handed presser rod 5L inserts the shuttles 6L1 to the blank pipe from the left-handed stocker 7L. Then, a right-handed presser rod 5R inserts the shuttles 6R1 to the blank pipe from the right-handed stocker 7R, causing the shuttles 6L1 to be entrained and returned to the left-handed stocker 7L. Vertical shift movement is alternately executed between the left-handed and right-handed stockers 7L and 7R, so that a shuttle of step-likely increased working height is selected for executing a working process.

Apparatus For Recovery Metal

InactiveUS20080142374A1Facilitate recovery and recyclingLarge shapeCellsPhotography auxillary processesMetalMaterials science
An apparatus for recovering a metal, which comprises a metal-recovering board (2) having an electrodeposition surface (2a, 2t) for the attachment of a metal component (R) precipitated from a solution and an insulating material (2b) formed around a pattern of the electrodeposition surface (2a, 2t). The metal-recovering board (2) is immersed in a metal-containing solution in an electrolytic treatment vessel (1), and thereby the metal in the solution is selectively precipitated on the electrodeposition surface (2a, 2t) and is converted to a bulk. The resultant metal bulk is scraped together for recovery with a blade (6) in a form as it is. The above apparatus for recovering a metal can be suitably used for recovering a metal in a solution in a state allowing easy reuse with good efficiency.

Hologram apparatus and hologram recording method

The present invention provides a hologram apparatus for recording an interference fringe of a signal beam and a reference beam having a speckle pattern in a recording area of a hologram recording material. The hologram apparatus includes a speckle pattern generating unit for generating the speckle pattern so that the speckle pattern is different in form in the track direction and the cross-track direction of the recording area. With this configuration, it is possible to perform recording under an increased tolerance in the cross-track direction while securing the shift selectivity necessary in the track direction, and, hence, to easily and stably perform the tracking servo at the time of reproduction.

Multi-directional input device

An object is to provide a multi-directional input device mainly used for operations of various electronic devices, the multi-directional input device being capable of performing various reliable operations. A movable electrode installed on a lower surface of a sliding body which is engaged with a lower end of an operation body is connected to a ground, and a plurality of fixed electrodes arranged so as to face the movable electrode with a predetermined gap is arranged at predetermined intervals. Thereby, the plurality of fixed electrodes facing the movable electrode can be formed in a large shape, so that a change in a capacitance due to operations of the operation body can be increased. As a result, not only the operating direction but also an operation amount can be precisely detected. Thus, the multi-directional input device capable of performing various reliable operations can be obtained.

Wear resistant center feed impact impeller

The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact crushers caused by earth aggregate flows during operation of impact crushers. The present invention includes a stepped central feed cone that allows for cylindrical carbide rods to be press fit therein to reduce wear. The downward steps of the stepped cone urge material fed to the stepped cone outwardly to the table. The top surface of a first rod inserted into a first bore formed in the impeller housing extends a distance beyond the bottom of a second bore on the next step up. The first rod protects the housing material forming the second bore from being washed out by material flow. In one embodiment, the impeller shoes have a geometric shape that reduces excessive normal forces and accompanying high friction of the material against the shoe. The reduction in high friction significantly reduces the wear rate.

Medical utility cupped fingertip glove

The medical utility-cupped fingertip glove is designed for use in hospital, homes and facilities where medical attention is provided. The invention encases the fingers, hand and arm, providing protection from contaminants. The device protects a patient's intravenous plug (IV) without feeder tube, whether located on the hand or the arm, while showering. There may be additional uses. The invention is designed to allow maximum use of hand and fingers by form fitting tips of the four phalanges and thumb, while providing sufficient leeway in the remainder of its design to easily fit over a protected area. The glove remains in place through the use of an elastic band that secures the uppermost portion of the glove midway between the wrist and the elbow, by wrapping securely around the arm. The invention is ambidextrous and has multiple sizes, dependent upon the body size of the user.

Large modal volume semiconductor laser system with spatial mode filter

A semiconductor optical amplification system that uses a single-mode fiber angle-coupled to a semiconductor wave-guide medium with optical gain. This design is particularly simple and relevant to optical fiber systems, but it may be generalized to include other implementations as well, in which other spatial mode filters are employed. A chip design is employed in which lowest order mode has a size greater than about 5 micrometers (μm). Thus, much smaller facet angles can be employed while still avoiding self-oscillation. More specifically, according to some aspects of the invention, facet angles of less than 4 to 5 degrees are utilized.
