Title: Antitussive preparation
Inventor: KASUYA YUTAKA
IPC: A61P43/00
Filed: 1990-06-14
Abstract: Commercially available antitussives which are widely used at present are problematic in that they contain dihydrocodeine which is officially designated as a narcotic or methylephedrine which is used as a starting material for a stimulant. An antitussive composition of the invention comprises a combination of an antitussive and L-tryptophan to enhance the antitussive effect. It has a similar antitussive effect even though the content of the antitussive is reduced, and is free from the side effect of aggravating the physical dependence of an antitussive.

Patent CA-2071130-A1 (CA)
Inventor: GUNNER CHRISTOPHER W
IPC: H04L12/56
Filed: 1992-06-12
Abstract: Abstract Communication Networks Fig. 1 A communication network consists of end units (EUs) and distribution units (DUs) coupled together by links which may include local area networks (LANs). The units maintain neighbour tables by sending out Hello messages which indicate the unit type and contain the network service access point (NSAP) IDs or addres-ses of the units. Data messages (packets) mainly originate and end at EUs. An EU maintains only partial routing information about neighbors while the DUs collectively maintain complete information about all NSAPs. So if an EU wants to send a pocket to an EU which is not a neighbour (and sometimes even if it is), it need merely send it to a neighbouring DU; that DU, along with the other DUs, must find a route to the destination EU. This invention provides a hybrid unit (HU), which acts as a DU to EUs but as an EU to DUs. The HU provides DU-like message forwarding but only on a local basis within a subnetwork of EUs and HUs.             Figure 5
Patent CA-2072264-A1 (CA)
Title: Thin-film transistor manufacture
Inventor: YOUNG NIGEL D
IPC: H01L21/336
Filed: 1992-06-25
Abstract: ABSTRACT                   THIN-FILM TRANSISTOR MANUFACTURE Source (51) and drain (52) of a thin-film transistor (TFT) are formed from a conductive layer (5) using a photolithographic step (Figure 3) in which the gate (4) serves as a photomask.  In accordance with the invention the insulated gate structure (3,4) is formed at the upper face of the channel-forming semiconductor film (2), i.e. remote from the transparent substrate (1).  The semiconductor film (2) may be annealed to high-mobility polycrystalline material before depositing the gate structure (3,4) and the overlying conductive layer (5).  In this way, high speed TFTs can be formed due to a combination of low gate-to-drain and gate-to-source capacitances and the provision of the transistor channel in the high quality semiconductor material adjacent to the upper face of the film (2).  Preferably ultra-violet radiation (20: Figure 1) is used for the annealing with an absorption depth less than the thickness of the film (2) so that the film-substrate interface is not heated which otherwise may weaken the adhesion of the film (2) to the substrate (1).  By using an angled exposure in a photolithographic and etching step with the gate (4) as a shadow photomask, a low-doped drain part can be defined from a conductive layer (5) comprising highly-doped material on low-doped material. This low-doped drain part reduces the effect of high drain bias in operation of the TFT.     (Figures 1,3 & 4).

Title: Ink container having atmosphere communicating section and recording head
Inventor: KARITA SEIICHIRO
IPC: B41J2/05
Filed: 1992-07-10
Abstract: An ink container (3) free from ink leakage against vibration and a shock and capable of reducing the evaporation of ink far greater than before and solving the problem of an increase in ink viscosity. Moreover, the ink container is a section for sale whose wrapping (6001, 6002, 6003) at a point of sales can be made inexpensive and simple and is totally constructed less expensively. Further, the ink container is capable of supplying ink for use with stability in case the ink is miscarried or leaks out and simultaneously or recovering the ink into the ink container. The container for containing ink has an atmosphere communicating section for making the inside communicate with the outside air, the atmosphere communicating section comprising a plurality of chambers (42, 43) outwardly communicating with each other, and the opening of each chamber is a port relatively smaller than the chamber. Preferably, the plurality of chambers are located in a direction intersecting a direction from the interior to the exterior and the openings of the plurality of chambers are positioned in such a way that they are shifted from each other. Recording liquid in a tank is prevented from leaking out via an atmosphere communicating port and this drives away a general feeling of uneasiness on the part of users deriving from the possibility of soiling their hands and clothes. <IMAGE>

Title: Procedure for upgrading the control system of a bank of elevators
Inventor: OVASKA SEPPO
IPC: B66B1/18
Filed: 1992-07-14
Abstract: A method for modernizing the control system of a bank of elevators, wherein in a first stage, the elevators are connected to work under elevator-specific computers controlled by a control system comprising a group controller and communicating  by  means of at  least one serial  communication bus.  The connection is effected using passive adapters between the computers and the old elevator controller. For completing the modernization process of the individual elevators, the elevator-specific functions are modernized by replacing their oldfunctions with functional modules and/or by adding functional modules performingnew functions. The  functional modules are  connected to the  elevator  computeron a serial bus, one at a time, for gradually replacing the old elevator circuits connectable to a serial communication bus.

Abstract: A method and apparatus for performing biomagnetic imaging to determine the location and intensity of current sources within a subject includes a sensor unit for sensing the magnetic field within the subject and for providing sensing signals.  A signal processor defines a grid having multiple grid points and performs inverse estimation to determine the distribution of current sources on the defined grid based on the sensing signals.  The signal processor then modifies the grid to improve the resolution of the current sources distributed on the grid.  A control unit controls the operation of the signal processor and processes image data to provide magnified and non-magnified displays on a display unit.  The biomagnetic imaging method and apparatus can be combined with a system for providing magnetic resonance imaging data so as to produce a superimposed display including an MRI image and a biomagnetic image.

Abstract: ABSTRACT         A reinforcing membrane in the form of an elastic sheath used with a balloon catheter to enhance the delivery of an intra-vascular stent of the kind delivered by a balloon catheter.  The sheath is interspaced between the balloon and the stent in the preferred embodiment.  The sheath acts as a protective barrier, provides for uniform expansion of the stent, decreases the defla-tion time of the balloon, prevents undesirable flattening of the balloon upon deflation and withdrawal, and, among other things, provides a friction substrate for the stent.  The sheath may be made into an elastic membrane that is applied on the inside or around the outside of the balloon.  The sheath may be formed of multiple co-extruded layers, with an outermost elastic layer.          Preferably the sheath is tubular and attached with adhesive, shrunk fit, or mechanically fastened to the outside of the balloon portion of the catheter.  The sheath may contain a radiopaque material that may also be used to indicate when the stent has been expanded to a proper operational diameter.
