  • Patent number: 5251071
    Abstract: The color filter according to the present invention contains black matrix formed by polyimide, which contains light shielding pigments such as carbon black, triiron tetraoxide, etc. instead of the black matrix used in the past, which is formed by metal thin film such as chromium on glass substrate. Epoxy type silane coupling agent is mixed with polyimide precursor composition, and this is coated on a glass substrate and then imidized. Thus, the color filter is provided with black matrix having high bonding strength with glass substrate.

  • Patent number: 5231675
    Abstract: An apparatus for inspecting sheet metal parts includes a computer for comparing a master representation to an inspected part. A part is scanned by passing the part in front of a computer vision system and an approximation of the part is thereby generated for comparison with the stored representation of a master part. The comparison includes checking for distance tolerances and proper feature placement of the scanned part and an inspection report for each inspected part is generated, indicating part acceptance status. Part tolerances may be varied for different parts and a library of parts may be consulted to automatically select an appropriate master part for comparison purposes.

  • Patent number: 5220426
    Abstract: Composite sync is separated from a video signal and integrated in order to produce a vertical control pulse. This pulse is then applied to the input of a one-shot multivibrator which provides an output essentially equal in duration to the time from the end of vertical sync to the start of the active picture, blanking the entire vertical interval with the exception of the vertical sync pulses. Optionally, a second one-shot multivibrator may be triggered at the horizontal sync rate and used to inhibit blanking during the times corresponding to equalizing, horizontal sync and color burst in order to preserve these legitimate parts of the signal. The first one-shot multivibrator may be replaced by a counter which counts at the horizontal rate and is reset by the vertical pulse. An increase in accuracy allows blanking of the period just before the vertical sync.

  • Patent number: 5214807
    Abstract: A vacuum toilet system comprises a small number of toilet bowls, a sewer, a small number of normally closed sewer valves connecting the toilet bowls respectively to the sewer, a sewage collecting tank in open communication with the sewer, a vacuum generator having a suction side in open communication with the sewer and operative to generate a partial vacuum in the tank and sewer, and a flush initiator associated with each toilet bowl for generating a toilet flushing impulse. A control unit is responsive to a toilet flushing impulse generated by the flush initiator associated with a given toilet bowl to cause the sewer valve connecting that toilet bowl to the sewer to open and the vacuum generator to operate for a predetermined time. In this fashion, a partial vacuum is generated in the tank and sewer of a level that depends on the free vacuum volume of the system.

  • Patent number: 5215080
    Abstract: An icing system is disclosed that has an insulating layer of wetsuit rubber, with a nylon pouch sewn onto it. The nylon pouch is divided, depending on configuration, into two or three compartments by hook and loop fasteners that are used in strips to both close the flap of the pouch and divide it into the compartments as desired. The compartments are designed to hold standard sizes of resealable sandwich and freezer bags half filled with ice. The multiple compartments allow varying amounts of ice to be put around different areas of the same body part, make it flexible, and permit a maximum of mobility on the part of the user. The wetsuit rubber that is used as an outer insulator allows this icing system to use ice with maximum efficiency, and yet makes the system flexible, light weight, non-leaking and non-irritating, permitting maximum mobility on the part of the user.

  • Patent number: 5214948
    Abstract: A method for forming metal parts from superplastic metal alloys uses axial compression of the blank starting material. A blank of the superplastic metal alloy is enclosed within a die press. The blank is generally tubular, although not necessarily circular, and has an aperture at each end. The ends of the blank are enclosed within correspondingly shaped sections of a cavity within the die press, while the center of the blank is disposed within a central cavity defining a desired shape of the metal part to be formed. Each end of the blank is then sealed with a ram or stop member, and the die press and blank are heated to a forming temperature that is within the superplastic temperature range of the metal alloy. Gas is supplied under pressure to the inside of the blank to produce an outward pressure urging the blank to deform outwardly within the central cavity of the die press.

  • Patent number: 5214500
    Abstract: Characteristics of a color encoder can be measured under the same condition as a practical operation without modifying the color encoder as a device under test. A test signal generator generates R, G and B component signals as test signals and they are applied simultaneously to the color encoder. The output amplitudes and/or output phases of the component signals from the test signal generator are adjusted such that the color encoder produces at least one of a luminance signal, an I-axis signal and a Q-axis signal in accordance with a measurement item.
