Granted: 1999-06-21
Abstract: A thermoelectric piece has an increased adhesive strength between a semiconductor matrix of Bi-Sb-Te or Bi-Te-Se and a diffusion barrier layer deposited thereon for blocking diffusion of a soldering material into the semiconductor matrix. An Sn-alloy layer is provided between the semiconductor matrix and the diffusion barrier layer of Mo, W, Nb and Ni to give the enhanced adhesive strength. The Sn-alloy is formed at the interface with the semiconductor matrix by interdiffusion of Sn with at least one element of the semiconductor. It is found that Sn will not lower the thermoelectric characteristics when diffusing into the semiconductor matrix and provides a sufficient adhesive strength to the metal elements of the diffusion barrier layer. The thermoelectric piece is made through the steps of: (a) preparing the thermoelectric semiconductor having opposed faces; (b) depositing a tin layer on each of the opposed faces of the thermoelectric semiconductor; (c) diffusing Sn mutually with at least one element of the thermoelectric semiconductor to form the Sn-alloy layer on each of the opposed faces; (d) depositing a diffusion barrier layer of Mo, W, Nb, or Ni on each of the Sn-alloy layer.

Granted: 1999-08-01
Abstract: This invention is related to the use of an absorbent core with multilayer of active material on top to form a bag shape diaper pad for use by male patients in hospitals, nursing homes and for those with incontinence. This product is made with a thin absorbent core wrapped up by layers of thin active materials to form a bag, and the opening portion of the bag is equipped with flexible mechanism. Simply clamp on the mechanism with fingers and apply force, allowing the mechanism to fold and open up, and then insert the penis into the opening. When the above force is released, the folded mechanism thereby bounces back and appropriately presses against the penis to avoid falling off of diaper pad. Since it only needs small amount of force to make the flexible mechanism fold, there is only minimal pressure on the penis, and one can even install it with single hand.

Title: A variable delay cell with a self-biasing load and method thereof
Inventor: JOHNSON LUKE A
IPC: H03K5/13
Filed: 1999-01-13
Granted: 2001-05-28
Abstract: A variable delay cell with a self-biasing load suitable for the implementation  of a voltage controlled oscillator and other functions. Because the invention employs current steering between symmetric loads and fully differential voltage control, it is very fast relative to conventional methods and has reduced jitter and improved power supply noise rejection. Additionally, since the load is self-biasing, the need to externally generate a bias current for the load is eliminated. The significantly simplifies design. Also as the load readily self biases in response to changes in the bias current of the biasing transistor, desirable functionalities can be achieved merely by appropriately changing the bias current into the biasing transistor. Notably, the slew rate of both the rising and falling edge can be controlled in this way. Because the load provides a fully differential output, noise immunity as well as a 50% duty cycle is readily achieved.

Title: Yarn processing device and use thereof
Inventor: RITTER HELMUT
IPC: D02J13/00
Filed: 1999-03-02
Granted: 2001-08-11
Abstract: The invention relates to a pin assembly which keeps single-piece, two-piece or multi-pieced yarn processing elements, especially yarn interlacing spinnerets or thermal treatment elements, in an exact position during an entire service life despite the extreme effects of preparations used. Instead of a traditional soldered joint or an adhesive connection, mechanical clamping means are used to fix the dowel pins to one part of the spinneret. Fixation of the dowel pins is not affected by heat or chemical preparations. The clamping means consists of a simple clamping ring holding the dowel pin in position directly inside the body of the spinneret between the clamping pin and an after-body. The novel positioning solution can be used with individual parts of spinnerets, parts of spinnerets in machines or multiple parts of spinnerets. The dowel pins enable the entire spinneret to be substantially miniaturized and allow narrow separation between various yarn runs, which was previously impossible. The invention can be used advantageously in interlacing spinnerets or in steam treatment elements.

Granted: 2001-06-07
Abstract: The position of an oblique mirror structure inside a polymer waveguide (1) in relation to an optical device is accurately defined by using an integrated mask of metal, which is defined using photolithography, on top of the waveguide structure. When irradiating the surface of the waveguide with laser light, it is only let through where no metal is left, so that the recess (19) formed is defined by edges of strips (15) of the metal layer. In the same metal layer also electrical contact pads (13) are produced used for self-aligning flip-chip mounting of devices such as lasers and photodiodes. Another metal layer (21) can be applied inside the waveguide structure at a place under the waveguide core so that it is hit by and stops the laser light. The energy of the laser will atomize the metal and the dispersed metal will then be deposited on the walls of the recess (19).
