Title: Memory protection
Inventor: KAZUHIRO HAYAMIZU
IPC: B41J5/30
Filed: 1990-04-26
Abstract: In a data processing device capable of attachably and detachably providing an external memory unit to which data are written and from which data are read, the external memory unit being capable of storing data even when it is not provided on the data processing device, provided are discriminating means for discriminating whether the external memory unit is provided on the data processing device, judging means for judging whether predetermined kind of data are stored in the external memory unit in case that it is discriminated that the external memory unit is provided on the data processing device, and another judging means for judging at least whether the predetermined kind of data stored in the external memory unit are operable in case that it is judged by the judging means that the predetermined kind of data are stored in the external memory unit. Thus, since a conventional check operation for the external memory unit is not executed, in the data processing device according to the present invention, when the predetermined kind of data are stored, the predetermined kind of data are not destroyed.

Title: Relay having a water sensor
Inventor: KANAZAWA NOBUYOSHI
IPC: A45D20/10
Filed: 1990-06-05
Abstract: A relay (1) comprises first and second input terminals (3a, 3b) electrically connected to respective first and second output terminals (4a, 4b) by first and second contacts (7a, 7b) and first and second sensor terminals (not shown) connected to respective first and second coils (6a, 6b). When the sensor terminals are electrically connected together eg by water, current flows through the coils (6a, 6b) to cause a movable element (9a) to be moved between a first stable position corresponding to a state where the contacts (7a, 7b) are closed and a second stable position corresponding to a state where the contacts (7a, 7b) are opened. The movable element (9a) is moved from the second stable position back to the first stable position by application of external force to a spring biased resetting member (9b). A water sensor for use in the relay comprises two conductors disposed on an insulator so as to be spaced by a distance of 5mm or less. <IMAGE>

Title: Towed sonar arrays
Inventor: PARSONS ALAN THOMAS
IPC: G01S7/52
Filed: 1990-06-29
Abstract: Low frequency vibration induced noise is reduced in a towed sonar aray of the type comprising n oil-filled modules 10 joined end to end with each module housing m hydrophones by arranging that at low frequencies the outputs from all the hydrophones in a module are added together at 30<SB>1</SB>...30<SB>n</SB> with uniform weighting and without relative phase delays so as to form respective single channel outputs. Beamforming is carried out by applying phase delays   W  <SB>1</SB>....  W  <SB>n</SB> to form a beam in a predetermined direction. High modulus internal strength members are included in each module to resist anti-phase vibration of the couplings at the end of the module. The hydrophone spacing and the coupling lengths are both made small compared to the module length to improve vibration noise reduction.

Title: Gas powered heating tool
Inventor: OGLESBY JOHN PAUL
IPC: F23D14/28
Filed: 1991-10-22
Abstract: A gas powered heating tool (1) comprises a handle (2) and a head (3) which comprises a soldering or other tool element (20). Gas from a reservoir (8) in the handle (2) is delivered through a gas supply pipe (23) to a combustion chamber (25) where it is converted to heat by a catalytic heating element (26) for heating the tool element (20). A nozzle orifice (19) in a nozzle (15) delivers a jet of gas through the gas supply pipe (23). The gas supply pipe (23) conducts heat from the combustion chamber (25) to a heat transfer member (35) which in turn conducts heat to the nozzle (15) to prevent freezing of gas in the nozzle orifice (19). Heat is also conducted to gas supply control means (12, 17, 18) in the handle (2) to prevent gas freezing.   <IMAGE>

Title: Optical fibre splicing using a one-piece collar
Inventor: WHITESMITH PETER JOHN
IPC: G02B6/255
Filed: 1992-04-02
Abstract: In positioning two optical fibres F relative to one another for fusion splicing, a collar 1 is disposed on each fibre spaced from the end to be spliced so that it cannot move with respect to the fibre without the application of a substantial force. Each fibre F is cleaved so that a tail T of a predetermined length protrudes from the collar 1. The tails T are introduced into opposite ends of a rectilinear guide passage 16 in the splicing station so that the collars 1 abut the remote faces of longitudinally spaced abutments 20. The lengths of the tails T are such that the end faces of the tails are disposed between the electrodes 19 an appropriate distance apart for fusion splicing. The collar 1 may be made of resilient material. <IMAGE>

Title: Metal contacts in semiconductor devices
Inventor: LEE SANG-IN
IPC: H01L21/28
Filed: 1992-07-08
Abstract: A wiring layer of a semiconductor device having a novel contact structure to prevent Al spiking is disclosed. The semiconductor device includes a semiconductor substrate 31, an insulating layer 32, having an opening (contact hole or via) and a first conductive layer 37 formed on the insulating layer 32, which completely fills the opening.

The semiconductor device may further include a second conductive layer 39, having a planarized surface on the first conductive layer. This improves subsequent photolithography. An anti-reflective layer 40, may be formed on the second conductive layer 39, for preventing an unwanted reflection during a photolithography process. The semiconductor device preferably also includes a diffusion barrier layer 34. A method of forming the wiring layer is also disclosed. <IMAGE>

Title: Record book or pad.
Inventor: DRAKE THOMAS ROGER
IPC: B41L1/36
Filed: 1992-11-25
Abstract: A record book or pad has its sheets formed in pairs each with a removable sheet 1 overlying a record sheet 2. The record sheets 2 are hound at a spine edge part 3 by binding rings 5. Opposed faces 1A and 2A of the sheets in each pair are provided with direct image transfer means (such as reactive coatings or ink capsules) by which a message applied by pressure to the removable sheet 1 is reproduced on the record sheet 2. Leaf edge parts 10 and 11 of the sheets in each pair are retained together by means which permits removal of the removable sheet 1 from the record sheet 2. Such retention may be by low tack adhesive 30 on the removable sheet 1, by permanent adhesive (20, Fig. 2) and a line of weakness (21) on the removable sheet 1 or by providing a line of weakness between the removable sheet and the record sheet where those sheets are formed by folding a single sheet. By retaining the leaf edge parts 10 and 11 together, a barrier sheet 25 may be interposed easily and selectively between successive pairs of sheets. Each removable sheet 1 may be extended by a filler sheet portion into the binding rings 5 to provide the book or pad with a uniform thickness. <IMAGE>

Title: Improved thermal capacity reticulated polymer foams
Inventor: INGLES DAVID ALAN
IPC: C08J9/00
Filed: 1993-05-28
Abstract: Reticulated polymer foams permitting a through and return flow of gasses have many uses, such as in conventional filters and 'heat and moisture exchange' devices. The thermal capacity of these foams is relatively low in comparison to other materials such as metals. In order to increase the efficiency of foams when used in HME's this invention provides for the incorporation of a filler material, such as for example fine aluminium powder, in the body of the foam in a way that ensures that it is substantially if not wholly encapsulated by the polymer fibrules comprising the cell walls of the foam. An electrically and thermally non-conductive reticulated polymer foam composition permitting a through and return flow of gases is characterised by comprising an insert powdered filler, eg a metal, having substantially higher thermal capacity than that of the polymer.
