Inventor: HUANG MING-CHUNG
IPC: G01C9/20
Filed: 1991-09-25
Granted: 1996-10-29
Abstract: An instrument for measuring angles, vertical line or horizontal line includes a square casing having two axial lines crossing at a center of the casing and having a colored liquid filled in the casing,  and a rotating disc rotatably mounted on the casing, in which the rotating disc is formed with an upper half circle portion radially formed with a plurality of angular graduations in terms of degrees, and formed with a lower half circle portion having two vertical columns parallelly formed below a diametrical line dividing the two half circle portions, and at least a reference line linked  between  any  two  horizontal  graduations respectively formed in the two vertical columns, whereby upon a rotation of the disc to parallel the reference line to a liquid level of the coloured liquid,  an angle can be obtained by matching the angular graduation with any one axial line when the casing is laid on or coincided with a plane to be measured.

Title: System and method to program a printing form
Inventor: HIRT ALFRED
IPC: B41N1/14
Filed: 1991-11-28
Granted: 1997-02-25
Abstract: To program or selectively image or erase a printing form (9) of ferroelectric material, in which the state of polarization  of discrete areas of the printing form is controlled, utilizes an electron beam (12) generated by an electron gun (1, 3) which is impinged against a surface area (30) of the ferroelectric printing form.  The beam is controlled in accordance with an image to be recorded, for subsequent printing, on the printing form; it is directed to the ferroelectric material by an electron beam focussing and accelerating  system, for example similar to the system used in a television camera.  The printing form (g) can be sealed with respect to an evacuated electron gun by a slide seal (14, 15) with a vacuum lock, or by a ferrofluidic vacuum lock (18, 20); or the electron gun can be closed by a Lenard window, or an end plate (27) with micro channels or micro ducts (26) therein.   The intensity of    the beam can be controlled by a suitable image control unit (32a).

IPC: H04L29/06
Filed: 1992-04-08
Granted: 1999-02-23
Abstract: A data processing system is described that employs data packets which include at least static and dynamic fields, the static fields containing information that often   remains   constant   during   a   multi-packet communication   interval   and  the   dynamic   fields containing information that changes for each packet. Many  packets  also  include  a  user-data  fields.  A compression  method  is  described  which  comprises: reformatting  each  data  packet  by  associating  its static  fields with a  first packet  region  and  its dynamic  fields  with  a  second  packet  region.   The process then assembles a static table that includes static  information  from  at  least  an  initial  data packet's  first  packet  region.   It  then  identifies static field information in a subsequent data packet's first packet region that is common to the information in  the  static  table.   Such  common  information  is encoded so as to reduce its data length.  The common static information is then replaced in the modified data packet with the encoded common static information and the modified data packet is then transmitted.  A similar  action  occurs  with  respect  to user-data information.  A single dictionary table is created for all packet headers, while separate dictionary tables are  created  for  each  user-data  portion  of  a packet-type experienced in the communication network thereby enabling better compression.

Granted: 2001-05-01
Abstract: A fiber preform is initially consolidated by being impregnated with a thermosetting impregnation composition that contains a ceramic precursor, and by heat treatment at the end of which the precursor has been transformed into ceramic, without passing through a meltable phase. The consolidated preform is then densified. The impregnation composition is constituted by a mixture of a thermosetting monomer and a ceramic precursor polymer, and the monomer is cross-linked during the heat treatment so as to achieve "in situ" cross-linking of the polymer mixture prior to transforming the precursor into ceramic.

Abstract: Cationic charged semihydrophobic polyethersulfone (CSHP) membranes having hydrophilic and semihydrophobic properties are provided, as wall as preparation of the same by post-treatment. Typically, as an illustration, a microporus hydrophilic polyethersulfone membrane substrate which contains non-teachable polymeric additive having functional groups is treated in an alkaline solution for simultaneous or sequential reaction with 1) a primary charge modifying agent which is an epichlorohydrin modified polyamine, and 2) a secondary polymeric charge modifying agent containing a positive charge (or for reaction with the primary charge modifying agent alone); then baked until cured at elevated temperature; and finally washed and dried. The CSHP membranes are used in various applications such as the filtration of fluids and the macromolecular transfer of biomolecules either from electrophoresis gels or directly to immobilization on the membrane for hybridization and stripping. The CSHP membranes - unlike conventional charged membranes which typically show a decrease in sensitivity and reprobing performance - retain their sensitivity and reprobing performance and excel in this regard throughout multiple reprobing cycles.

Abstract: A gasketed membrane electrode assembly for electrochemical fuel cells employs gasketing material at the periphery of the ion exchange membrane, rather than the membrane itself, as a gasket. The gasketing material may be formed from an elastomeric material suitable for cold bonding or bonding by heat and pressure. A nonhydrophilic thermoplastic elastomer is the preferred gasketing material. The gasketed membrane electrode assembly provides a seal between the electrically conductive separator plates that is more effective and economical than assemblies employing the membrane itself as the gasketing material. In an alternative embodiment, a gasketed membrane assembly for use in the humidification portion of a fuel cell employs gasketing material at the periphery of a water permeable membrane.

Abstract: An improved analogue photodiode module is provided herein. This improved analogue photodiode module includes an optical fibre having an end for transmitting light beams including a plurality of amplitude-modulated signals of different frequencies. A ball lens is provided for converging the light beams which are emitted from the optical fibre at different points on a central axial line, the beams which are closer to the central axis being converged at farther points from the ball lens, and the beams which are farther from the central axis being converged at closer points to the lens. The ball lens provides a maximum sensitivity range with a definite length for the position of an end of the optical fibre. The ball lens provides an aberration which makes a peak of signal distortion at a point which is farther than a middle point (Z0) of the maximum sensitivity range from the ball lens, the end of the optical fibre being positioned at a point (Z1) which is within the maximum sensitivity range which is closer to the lens than the middle point (Z0) and giving a second order distortion IMD2 which is lower than a predetermined value. A photodiode is provided for receiving light beams which are converged by the ball lens and for converting the light beams electric signals. A package is provided for holding the photodiode, and a cap is provided for sealing the package and for supporting the ball lens. A ferrule is provided for holding an end of the optical fibre and a holder is provided for fixing the ferrule to the package. Thus in the present invention, the end of the fibre is positioned at a point which is closer to the lens than the maximum sensitivity range and gives distortion which is smaller than the predetermined value.      High sensitivity and low distortion are compatible at that point.
