Title: Process for production of copper through-hole printed wiring boards
Inventor: YAMAGUCHI HIDEAKI
IPC: H05K3/42
Filed: 1992-03-24
Abstract: Copper through-hole printed wiring boards are produced by forming an etching resist layer on the copper plating of a double sided copper clad laminate.      The etching resist layer is formed after a negative resist pattern is applied to both sides of the laminate, and the laminate then dipped in a solution containing at least one salt of 2-alkylbenzimidazoles, 2-alkylalkyl-benzimidazoles, 2-phenyl-benzimidazoles and 2-phenyl-alkylbenzimidazoles. After the resulting etching resist layer is selectively removed. with an alkaline aqueous solution, in accordance with the predetermined pattern of the wiring, the exposed copper plating is etched off with an alkali etchant. According to the process of the present invention, remarkable advantages such as increased productivity, lower production costs, reduced toxic substances in waste water, and a high reliability can be obtained in the production of copper through-hole printed wiring boards.

Title: Retinoid receptor compositions and methods
Inventor: MANGELSDORF DAVID J
IPC: C12N15/12
Filed: 1991-01-22
Abstract: The present invention re-lates to novel receptor polypep-tides, which, upon interaction with certain ligands, or activation by certain compounds, modulate transcription of certain genes by binding to cognate response ele-ments associated with promoters of such genes. The novel recep-tors of the invention modulate transcription in the presence of retinoid compounds. The recep-tors of the present invention dif-fer significantly from known reti-noid acid receptors, in protein primary sequence and in respon-siveness to exposure to various retinoids. The invention provides DNAs encoding the novel recep-tors, expression vectors for ex-pression of the receptors, cells transformed with such expres-sion vectors, cells co-transformed with such expression vectors and with reporter vectors to monitor modulation of transcription by the receptors, and methods of using such co-transformed cells in screening for compounds which are capable, directly or indirectly, of activating the receptors. The invention also provides nucleic acid probes for identifying DNAs which encode additional retinoid receptors of the same class as the novel receptors disclosed herein.

Abstract: PROCESS FOR PREPARING MONOAMIDO ACIDS ABSTRACT OF THE DISCLOSURE There is disclosed a novel process of preparing highly pure monoamido acid by the reaction of a dibasic acid and an amine wherein a large molar excess of dibasic acid is utilized and conveniently recovered for recycle in the process to prepare additional amounts of the said monoamido acid. It has been discovered that amidation of both acid groups of the dibasic acid is held to low levels while efficiency of the reaction is maintained by recycle of unreacted starting acid. The unwanted diamido compound is separated from the desired product by first forming a water soluble salt of the monoamido acid then removing it from the insoluble diamido by-product by conventional means such as filtration. The desired monoamido acid may be recovered by acidification of the salt thereby precipitating the acid for easy recovery from an aqueous medium.
Patent CA-2102393-A1 (CA)
Inventor: HERMANN KERSTAN G
IPC: F26B21/08
Filed: 1993-11-03
Abstract: The present invention utilizes a membrane cartridge that removes water vapor or fluid from air that passes through the cartridge. The longer the air remains within the cartridge, the more fluid is removed from the air.      Consequently, as the air becomes "drier", the dew point temperature of the air also falls. The present invention permits decreases in the flow rate and system pressure while providing dehumidified air with the desired dew point temperature. These decreases in pressure and flow rate result from increased elevation or system wear. The decrease in system pressure and flow rate increases the residence time of the air in the membrane cartridge. As a result, the dew point temperature of the dehumidified air remains stable because increased residence time increases the amount of fluid removed from the air, which tends to reduce the dew point temperature of the dehumidified air.
