Patent MX-9604082-A (MX)
Title: Expansion joint cap.
Inventor: CORRIE DAWN
IPC: E01C11/10
Filed: 1996-09-13
Abstract: A resilient expansion joint insert member for insertion into the expansion joint between adjacent concrete floor slabs. As the concrete slabs move further apart due to settling or thermal contraction, the insert member covers the widened gap. Likewise, as the concrete slabs move closer together due to settling or thermal expansion, the insert member is compressed and absorbs the force as the slabs move against each other. The flooring material on the slabs near the expansion joint move beneath a cap of the insert member.

Title: Tampon applicator having rolled gripper.
Inventor: ISKRA MICHAEL J
IPC: B31B17/00
Filed: 1995-12-22
Abstract: A method of forming an improved finger grip at the gripper end of a paperboard tampon tube is disclosed. This gripper end has an outwardly rolled edge produced by applying moisture to the gripper end of the paperboard tube having a diameter of less than about 25 mm, heating a forming tool to about 100 degree F to about 350 degree F, rotating the paperboard tube with respect to the forming tool at a rate of about 50 to 1000 rpm, and contacting the gripper end of the paperboard tube with the forming tool for about 0.2 to about 5 seconds. In this manner, the forming tool rolls the gripper end of the paperboard tube outwardly to form a radiused surface at the outside of the gripper end of the paperboard applicator tube.

Patent NL-2022765-A (NL)
Title: Step-by-Step Doping Method of Phosphorous for High-efficiency and Low-cost Crystalline Silicon Cell
Inventor: JIANNING DING
IPC: H01L31/18
Filed: 2019-03-19
Abstract: The invention relates to the technical field of solar cell manufacturing, and to a high-efficiency low-cost step-by-step doping method of phosphorus for a crystalline silicon cell. The method comprises a depletion-type phosphorus diffusion, a high-concentration shallow layer diffusion and back-etching. The low-temperature low-phosphorus deposition is performed on a p-type silicon substrate by controlling the oxygen flow rate, the nitrogen flow rate, and the phosphorus oxychloride flow rate, and then the phosphorus in the phosphorosilicate glass is depleted by a long period of high-temperature drive-in to achieve a low surface concentration layer n+. A second deposition and drive-in are performed on the non-phosphorus glass to increase the surface concentration, and thus form a very thin high-concentration layer n++, which can be quickly etched away by back-etching. The distribution of phosphorus dopant in different regions can be independently and precisely controlled, to ensure a low doping concentration and a low recombination current in a non-electrode region, thereby ensuring a high open-circuit voltage. An electrode region has a high doping concentration, and has a good ohmic contact with a metal electrode, such that the fill factor is not compromised, thereby improving the photoelectric conversion performance of the cell on a whole.

Patent NL-8004598-A (NL)
IPC: G06F3/06
Filed: 1980-08-14
Abstract: A description is given of a method and an associated device for the writing and reading of information into and from a record carrier body. The record carrier body is preferably made of a radiation-sensitive medium and comprises a servo track. The information is written in consecutively arranged sectors and is read directly after writing for the purpose of verification. A vector address VA(n) is added to the amount of information to be written in a sector. A vector address of this kind indicates a previously inscribed sector of the record carrier body, said previously inscribed sector having the property that the information has been correctly written therein. The added vector address enables the transfer of only the correctly written information to a user when the written information is read. The use of so-called <<interleaving>> during the inscribing of information in the record carrier body protects the information written against an error burst.
