Title: Wall plugs
Inventor: YAMAMOTO AKIO
IPC: F16B13/14
Filed: 1992-08-12
Abstract: A wall plug for use in soft material comprises resin flow openings 11, projecting rings 15 for engaging the wall of a hole in the soft material, and projecting wings 17 which are bent inwards by the hole wall as the plug is inserted into the hole, so as to form a flow control cup 19 open towards the mouth 5 of the plug. Resin is supplied to the mouth 5 and flows into annular spaces between the projecting rings 15, and into the cup 19. A screw is then screwed into the mouth 5 and opens the junctions 31 so that resin permeates the soft material. The cup 19 raises the pressure of the resin in the hole, but permits some leakage. <IMAGE>

Title: Process for metallizing substrates using starved-reaction metal-oxide reduction
Inventor: BROWN VERNON L
IPC: C04B41/88
Filed: 1993-03-15
Abstract: A unique process metallizes a substrate surface using a reducing agent including a borohydride to reduce, in a starved reaction, metal oxide particles (300) substantially uniformly distributed and at a controlled concentration in a particle-filled resin (204) to produce catalytic island areas (301). The catalytic island areas (301) formed have a surface resistivity greater than 10<6> ohms per square. These catalytic island areas (301) are then electrolessly metallized to a predetermined thickness, such that adjacent catalytic island areas (301) are interconnected and form metallic features, such as pads, vias (213), and conductors (210, 211 and 212). The starved reaction limits the reduction of metal oxide particles (300) to catalytic island areas (301) and prevents migration of reduced metal beyond each of the exposed surfaces of particle-filled resin (204) which are to be metallized. <IMAGE>

Title: Microprocessor and banked memory.
Inventor: BJERGE CLAUS
IPC: G06F9/42
Filed: 1994-04-29
Abstract: An electronic device having a microprocessor and banked memory (otherwise known as virtual memory). A first program is run from a first banked memory (15, Fig. 2). An access program is loaded from the running program into common RAM (11). The access program is run from common RAM and actuates a memory switch to disconnect the first banked memory from the microprocessor and to connect in its place a second banked memory (16). Memory access operations are performed to the second banked memory. The access program activates the memory switch to disconnect the second banked memory and to reconnect the first banked memory and running of the first program is recommenced. By storing the access program in RAM, there is less usage of common memory space than if the access program were stored in common ROM (12). <IMAGE>

Title: Flexible tow bar
Inventor: FRY CLIFFORD HENRY
IPC: B60D1/155
Filed: 1994-07-29
Abstract: A flexible tow bar is made up of disconnectable interlocking sections 5 between female and male tow hitch members 1, 2, to enable easy transport and portability by hand. The flexible tow bar will allow easy connection of the bar to (for example) a trailer in a dry but very muddy harbour to a towing vehicle on a slipway without the need of taking the towing vehicle into danger, or to remove or launch a boat from a trailer at any stage of the tide with far greater safety than present methods since the hinged section will follow the contours of the ground's surface, and a swivel/ball joint 4 will allow easy fitting of the hitches at odd angles, also a floating boat will not be impeded by the bar because of its flexibility, yet it will give greater stabilisation and safety than the present methods in use. To prevent articulation between two sections 5 a bolt is fitted through holes 11 in one section and a slidable member 10. <IMAGE>

Title: Variable displacement high pressure pump for common rail fuel injection systems
Inventor: YEN BAI-MAO
IPC: F02M59/44
Filed: 1994-05-06
Abstract: A variable displacement high pressure pump having a plurality of high pressure pumping units which receive fuel from a low pressure fuel pump. A rotary cam-driven roller tappet, for producing pumping displacement of the pumping plunger of a respective pumping element, is connected to the pumping plunger by a separated lid in a manner permitting the pumping plunger to float relative to the roller tappet during at least a portion of each pumping cycle. As a result, the capacity of the pumping chamber can be limited to an extent that is less than the full stroke achievable by the pumping plunger being retracted to the maximum extent which is permitted by the driving cam. In this way, the quantity of fuel to be pressurized and injected into the common rail does not have to be determined by a cutting-off of a spilling flow of excess metered fuel during the compression stroke of the pumping plunger, so that a low pressure solenoid valve can be used, in the case of time-stroke and time-pressure metering, and no solenoid is required to control metering in the case of pressure-time metering. <IMAGE>

Title: Semi-conductor light emitting device, laser amplifier and intergrated light ampier and wavelength variable filter
Inventor: KAKIMOTO SYOICHI
IPC: B82Y20/00
Filed: 1995-05-30
Abstract: A double heterojunction structure comprising an active layer (2), a cladding layer (3) having a first conductivity type, and a cladding layer (1) having a second conductivity type, which cladding layers (3, 1) sandwich the active layer (2), and an undoped cladding layer (4) interposed between the first conductivity type cladding layer (3) and the active layer (2), which undoped cladding layer (4) comprises the same material as the first conductivity type cladding layer (3) and has a thickness larger than the diffusion length of carriers in the undoped cladding layer (4). Therefore, carriers are accumulated in the undoped cladding layer (4) and then regularly injected into the active layer (2) by Coulomb repulsion between the carriers, resulting in a semiconductor light emitting device with reduced heat generation, reduced fluctuation of emitted laser light, and reduced noise. An alternative arrangement (Figure 8) uses instead two additional doped cladding layers (32, 36) separated by a distance greater than the carrier diffusion length. <IMAGE>
