Title: Absorbent article having dual cuffs
Inventor: LAWSON MICHAEL I
IPC: A61F13/15
Filed: 1986-10-11
Granted: 1994-09-28
Abstract: An integral disposable absorbent article such as a diaper having a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, at least one elastically contractible gasketing cuff, and at least one barrier cuff. The barrier cuff has a proximal edge and a distal edge. The absorbent article is additionally provided with spacing means for spacing the distal edge away from the top surface of the topsheet. In addition, adhesive means secure the end portions of the barrier cuff closed. A channel is formed between the proximal and distal edges in at least the crotch region because the distal edge is spaced away from the topsheet top surface.When the diaper embodiment of the present invention is applied to a wearer, the barrier cuff rides up along the inner thighs and the perineum of the wearer in the crotch region and along the buttocks in the back waist region. Leakage prevention is enhanced because body exudates which are not immediately absorbed by the absorbent core contact the barrier cuff and are contained and held within the channel so that they do not wick out of the diaper or flow out of the gaps between the diaper and the legs or waist of the wearer. Additionally, should such exudates flow beyond the barrier cuff, leakage is further enhanced by the gasketing cuff because it forms an additional fluid impervious barrier about the leg or waist of the wearer.

Title: Forming contacts on diamonds
Inventor: PRINS JOHAN F
IPC: H01L31/02
Filed: 1987-06-20
Granted: 1995-09-01
Abstract: The invention provides a method of preparing a detector which is sensitive to ionising radiation or atomic emissions. The method includes the steps of forming at least two discrete conductive regions (10, 12) on a counting diamond (14) by ion implantation, at a temperature below 500 DEG C. Subsequently, contacts (16, 18) are applied to the conductive regions to allow charged carriers liberated by the radiation to be detected by an electronic circuit. The invention extends to a detector prepared according to the method. An example of a detector according to the invention comprised a synthetic diamond having a paramagnetic nitrogen impurity concentration of less than 150 parts per million. Two conductive regions were formed on the diamond by bombardment with carbon ions, and contacts were formed on the conductive regions by the applications of silver-loaded epoxy paint.

Abstract: The olefin based resin having good coating property is composed of 40-80 wt% crystalline polypropylene resin, 1-50 wt% thermoplastic olefin based rubber component crosslinked dynamically with 10-70 wt% crystalline polypropylene resin and 90-30 wt% ethylene-alpha-olefin rubber, 0.5-30 wt% modified polypropylene resin prepared by grafting the polar monomer which does not react modified polyethylene copolymer and has the physical compatibility, 1-30 wt% modified ethylene copolymer prepared by grafting alpha, beta-unsaturated carboxylic acid or its derivatives, and less than 40 wt% inorganic filler such as calcium carbonate, barium sulfate, talc, carbon fiber etc.
