Title: Driving method of edge emission type el printer
Inventor: TAMURA TOSHIYUKI
IPC: H04N1/04
Filed: 1989-12-01
Abstract: PURPOSE:To improve printing quality and speed by setting a relation between a time for forming a single main scan line and the number of repetition of line light emission, during a time interval to be elapsed before the intensity of light emitted from an edge emission type EL element goes to zero after emission of light. CONSTITUTION:Assuming S is a time to be elapsed before the intensity of afterglow of an edge emission EL element goes to zero, T is a time required for formation of a single main scan line and K is the number of repetition of line light emission, there is a relation S>T/K. Since light emitting operation of the edge emission type EL element, which is repeated plural times, is started when afterglow of preceding light emitting operation still exists, light emission intensity of line head is enhanced resulting in improvement of printing quality and printing speed.

Title: Production of liquid crystal display panel
Inventor: ARAI KAORU
IPC: G02F1/13
Filed: 1987-12-09
Abstract: PURPOSE:To obtain a liquid crystal display panel which can save a liquid crystal by such a method which does not hinder scribing by constituting the liquid crystal display panel in such manner that an aperture for packing the liquid crystal can be disposed in the symmetrical positions of the panel. CONSTITUTION:The aperture 4 for packing the liquid crystal is provided on the center line C of the liquid crystal and is disposed in the position symmetrical with the region enclosed by a sealing line 3. A packing path 16 communicating the aperture 4 and the liquid crystal packing port 15 and a stopper 17 for preventing infiltration of the liquid crystal are formed to an excess region 6 cut off from a scribing line 5. Since the liquid crystal packing port 15 is formed at the angle part of the liquid crystal display panel in such a manner, the sticking of the liquid crystal to the surfaces of glass plates is minimized. Since the stopper 17 exists, the infiltration of the liquid crystal into the spacing between two sheets of the glass plates is prevented and the wasteful consumption of the liquid crystal is obviated. The material cost is thus saved. The stopper 17 is cut off as well at the tie of cutting off the excess region 6 and, therefore, the stopper 17 does not hinder the scribing.

Title: Mr imaging method
Inventor: TAKEO KAZUHIRO
IPC: A61B5/055
Filed: 1991-10-31
Abstract: PURPOSE:To perfectly remove a band-like artifact by changing the phase of high frequency pulse every line, and determining the order of phase encoding in such a manner that the change step of magnitude of phase encoding inclined magnetic field pulse is not constant. CONSTITUTION:A band-like artifact shown on an image when the magnitude of a phase encoding inclined magnetic field Gy pulse is changed is considered to be caused from the uneven distribution of the ability for spoiling a horizontal magnetization by the Y-directional position because the magnitude of Gy pulse is a function on the Y-directional position when the change step every line of the phase encoding inclined magnetic field Gy is a constant as in the past. Thus, by changing the phase encode quantity in the order as never making the change step of magnitude of the Gy pulse constant, the band-like artifact can be removed.

Title: Local drug release equipment
Inventor: ADORIAN FURANSHISU DEEBISU
IPC: A61K47/00
Filed: 1987-12-11
Abstract: A pharmaceutical composition for topical administration consisting of two liquid phases designed to be admixed in situ or prior to use. The first phase contains a dissolved drug, and is preferably saturated in the drug, whilst the second phase is a chemically or physically different liquid from that in the first phase and contains no drug, but is miscible with the first phase. The two liquids are selected so that, on admixture of suitable volumes of the phases, the resultant drug concentration exceeds the saturated drug solubility in the resultant mixture. This produces a liquid mixture supersaturated in drug, which has been found to increase the rate of drug penetration into the skin. The two liquid phases may be gels, and the drug may be hydrocortisone. At least one phase contains an antinucleant to improve stability of the resulting supersaturated solution.
