  • Patent number: 5094376
    Abstract: A holster for an automatic hand weapon and retention system which secures the weapon at the weapon's ejection port and trigger guard against unintentional withdrawal yet is made of lightweight, durable and inexpensive materials is provided. The holster is formed from a piece of fabric of synthetic material which is folded on itself and stitched to form a cavity for receiving the weapon. A first dowel is secured in a first pocket positioned above the muzzle end of the ejection port of the weapon. A second dowel is secured in a second pocket positioned in the trigger guard of the weapon. The first and second dowels engage the ejection port and trigger guard, respectively, of the weapon to prevent the removal of the weapon by an opponent or accidentally during strenuous activity by the user. Also provided is a holster suitable for wearing against a leg which has at least one dowel secured in a pocket positioned above the muzzle end of the ejection port of a weapon.

  • Patent number: 5092502
    Abstract: A hanger is comprised of an integral body or snythetic material having a central portion, a hook portion extending outwardly of the central portion and first and second wing portions at respective opposed side margins of the central portion. The central portion defines, at each side margin thereof, a succession of diversely-sized projections extending outwardly of the side margins, the projections being of generally arcuate configuration and each of successively lesser size progressively distal of the hook portion. Each wing portion comprises a member cantilever-supported by the central portion, each such cantilever-supported member defining mutually with the projections, spacings of successively lesser measure progressively distal of the hook portion.

  • Patent number: 5093262
    Abstract: To produce organic fertilizer which is effective for sterile agricultural land, a mixture comprising coral reef powder, domestic animal excreta, sewage disposal waste and ground cellulose derived from plant fiber is prepared and it is well mixed in the presence of organic compounds and inorganic salts. Thereafter, it is subjected to cultivating in a multi-bath type cultivating bath for a predetermined period of time while temperature and pH are adjusted properly. Cultivation is achieved with the addition of bacilli including nitrogen fixing bacillus such as Azotobactor vinelandii, Bacillus megaterum, Rhizobium leguminosarm or the like, Trichoderma virde acting as raw fiber decomposing bacillus, candida utilus acting as yeast fungus and green algae, each of which is cultivated under the operating condition of symbiosis cultivation. The pH in the cultivating bath is maintained in the range of 5.5 to 7.5, preferably in the range of 6 to 7.

  • Patent number: 5092926
    Abstract: An ink-jet printing ink composition which has high printing stability after long periods of time and at high temperatures is provided. The ink-jet printing ink composition is an aqueous ink having a nitrite ion concentration between about 0.2 to 10 parts per million (ppm) in order to lower the concentration of dissolved gas in the ink.

  • Patent number: 5093738
    Abstract: A method of forming a color filter substrate having pixels of at least two different colors by use of a negative photoresist material of the last color deposited. The negative photoresist is coated over the pixels and the exposed surface of the substrate. The back of the substrate is then exposed to a light source at a wavelength blocked by the formed pixels so that any of the negative photoresist material directly on the transparent substrate is activated by the light from the light source and remaining material is removed.

  • Patent number: 5093276
    Abstract: A novel semiconductor device and method of production of such a device are provided. Both the N and P channels of the novel semiconductor device are formed by contact self-alignment, thereby permitting high speed operation and high density integration to be realized. The formation of the channels by contact self-alignment is accomplished by depositing a P type polysilicon layer on an N well region and an N type polysilicon layer on a P well region. A silicide layer is formed over both the P and N type polysilicon layers to form a polycide.

  • Patent number: 5091736
    Abstract: A thermal print head including a glass layer disposed at the edge of a heat resistant substrate, a heat generating element on the glass layer and an electrode for driving the heat generating element disposed both under the glass layer and on the heat generating element is provided. The glass layer is formed of a lower layer of crystallized glass on the electrode and an upper non-crystallized glass portion under the heat generating element. The electrode under the glass layer is formed by print burning a thick conductive film on the substrate from a metal paste having a higher burning temperature than the burning temperature of the glass layers.

  • Patent number: 5090828
    Abstract: A method and apparatus for replenishing depleted portions of an ink sheet including a conductive ink layer on a dielectric layer wherein portions of ink have been transferred to a transfer medium. Conductive replacement ink material is supplied to the ink sheet and an electric charge is induced in the replacement ink and opposite charges are induced at an electrode on the opposite side of the dielectric layer. Replacement ink contacting the dielectric layer at the voids will adhere to the ink sheet, but charges in the replacement ink contacting the non-transcribed ink regions will flow to the conductive ink layer and will not adhere to the ink sheet.

  • Patent number: 5088844
    Abstract: A printer including an impact dot print head for driving a plurality of print wires mounted on the cantilevered end of print levers is provided. The print head includes a stopper positioned to be impacted by a print lever returning from a print position to an at rest position before a plunger on the lever impacts the magnetic core. A spring mounted on the lever biases it towards the print position. Magnetic flux of a permanent magnet attracts the plunger to the non-print position. An electromagnetic coil is energized to cancel the magnetic attraction of the plunger to the core to drive the wire towards the print position.
