Title: A method for manufacturing an ink jet head, and an ink jet head
Inventor: INADA GENJI
IPC: B41J2/16
Filed: 1996-06-17
Abstract: A method for manufacturing an ink jet head comprises a first step of arranging on a substrate a passage molding material to form ink paths conductively connected to discharge ports for discharging ink, a second step of arranging on the substrate an edge portion molding material in the vicinity of the passage molding material, a third step of arranging on the substrate a wall formation material to cover the passage molding material and the edge portion molding material, and a fourth step of forming the paths with the wall formation material by removing the passage molding material from the substrate.  With this method, it is possible to manufacture an ink jet head having an ink chamber and nozzles, which are configured substantially the same as the molding members, without creating cracks and other defects that are liable to occur on the extruded corners of the passage molding material with respect to the substrate when the conventional technique is applied.

Title: Light modulating microdevice and method
Inventor: JEROMINEK HUBERT
IPC: G02B26/08
Filed: 1996-11-14
Abstract: The invention relates to spatial light modulators (SLM) for amplitude and phase modulation of incident light. A "flexure" hinge which is provided between the SLM's substrate and micromirror comprises integral hinged sections which allow for the micromirror to tilt or to move in a piston-like fashion relative to the substrate in response to an electrostatic force. The hinge is particularly advantageous for large mirrors. In addition, the hinge can provide improved heat sinking capability over previously reported SLM hinge designs based on torsion bars and cantilever beams. The flexure hinge has sufficient mechanical flexibility that the SLM actuation voltage required is not excessively high.      The flexure hinge has many applications, the preferred ones being a SLM for modulating high-energy beams and a SLM for optical channel switching.

Title: Paging method and apparatus
Inventor: WONG GABRIEL K Y
IPC: H04W88/18
Filed: 1995-06-15
Abstract: A two-way paging system utilizes four local frequencies for transmissions between pager units (22) and a central control station (20). A first local frequency (f1) carries a local clock; a second local frequency (f2) carries communications packets from the central control station to paging units; a third local frequency (f3) carries communications packets from the pager units to the central control station; and a fourth local frequency (f4) carries a status or request signal from the paging units (22) to the central control station (20). Transmissions on the fourth local frequency (f4) are in accordance with a time divided slot allocation among pager units accessing the central control station (20). For a two-way paging system having a plurality of central control stations (420x) servicing a corresponding plurality of cells, a total of eight frequencies are utilized within any one cell. Four of the utilized frequencies are the local frequencies (f1-f4) ¢which may differ from cell to cell!, and four of the utilized frequencies are lower power common frequencies or switching frequencies (C1-C4) which are used to switch or hand-off a pager unit (422) traveling from one cell to another.

Title: Inhibition of the growth of micro-organisms
Inventor: ULRICHSEN BORRE BENGT
IPC: A23L3/3436
Filed: 1995-10-19
Abstract: Non-sterile liquids such as fresh milk (and milk products) and fresh fruit juices unfortunately provide an excellent growth medium for micro-organisms, whether aerobic or, like many yeasts and bacteria, "facultatively anaerobic" micro-organisms (meaning that in theory they do not need oxygen for their metabolic processes and yet are not actually poisoned by oxygen, and so can exist in its presence). It has been found, however, that in fact such microorganisms do seem to require oxygen for some part of their metabolic processes - or, at least, that in a virtually oxygen-free environment their growth is significantly inhibited. Thus, the invention proposes controlling the growth of micro-organisms in non-sterile liquids, such as milk and fruit juices, by the use of an oxygen scavenger to remove virtually all the free molecular oxygen from within the container in which the liquid is stored.
