Title: Assembly of glass sheet and a sash
Inventor: SUGIYAMA HIROKAZ
IPC: E06B3/54
Filed: 1977-03-18
Granted: 1981-06-16
Abstract: This method is for fixing a glass sheet to a sash having a channel defined by a bottom wall and side walls.  The process comprises: fixing the glass sheet to the channel at the fixed position, and the elastic spacers between the channel and the peripheral edge of the glass sheet at regular intervals; inserting the supporting materials into the intervals of the elastic spacers; filling up an initially softened or liquid and subsequently hardened elastic sealing material between the edge of the glass sheet and the walls of the channel, therefore the glass sheet is fixed to the channel, and said seal is substantially fluid-tight and covering the entire periphery of the glass sheet.

Granted: 1983-05-24
Abstract: Oriented textured filaments are manufd. by melt spinning a thermoplastic through a spinneret contg. 2 orifices, merging the 2 streams formed, and quenching. Thus, a spinneret was constructed with a 1st orifice tapering 30≰towards a 0.013-in.-diam. exit and a 2nd orifice with a 0.044-in.-diam. counterbore inclined at 15≰to the spinneret plate and having a 0.013-in.-diam. exit situated 0.043 in. from the 1st orifice exit. Nylon 66 was melted and spun at 2.83 g/min through the spinneret, quenched by a transverse air stream moving at 773 yd/min, and drawn to draw ratio 2.0 to form an 18-denier filament which produced substantial crimp on heat relaxation.

Inventor: REUTELINGSPERGER CHRISTIAAN
IPC: C07K14/195
Filed: 1990-07-14
Granted: 1998-11-16
Abstract: The present invention relates to processes for purifying annexines. The overall process includes the steps of preparing a homogenized cell preparation and adjusting the pH to about 8.0 to 10.0, adding at least one bivalent cation, adding a phospholipid, washing the insoluble cell residue to remove the soluble constituents, and extracting the annexines from the cell residue with a chelating agent. This process initially promotes the adsorption of the annexines onto the insoluble cell residue or membrane of the host organism. The adsorption step makes it possible to eliminate unwanted soluble matter from the homogenized material by simple washing. Desorption is accomplished by using a chelating agent.

Title: Dram enhanced the speed of sensing operation
Inventor: KO HWA-SU
IPC: G11C11/407

Abstract: Dynamic RAM (DRAM) with high speed sensing operation obtains high speed sensing operation by locating separately sense amplifier circuits on both sides of a transfer transistor in order to reduce parasitic capacitance. The DRAM comprises a cell array (11) storing data; an I/O control unit (14) transferring stored data into I/O lines; a separate unit (12) separating the first and second bit lines in order to obtain high speed sensing; primary and secondary sense amplifiers (13,16) sensing the first and second bit lines; a precharge unit (15)
