Title: Color wheel for picture generation unit
Inventor: EDLINGER JOHANNES
IPC: G02B7/00
Filed: 1997-04-03
Abstract: A color wheel 1 includes a disc-shaped carrier 11 rotatable about a central axis 10 and planar color filter segments 12a-c fixed to the periphery of the carrier. The bonding of the segments 12a-c to the carrier 11 is achieved using an adhesive in a strip-shaped bonding zone 13 so that the filter segments 12a-c are free of openings and provide a ring-shaped translucent area that is not interrupted by carrier elements such as retaining ribs between the segments 12a-c. The wheel may also include an eccentrically located recess 18 that can be partially filled with a cement or other material for rotationally balancing the wheel to withstand high centrifugal accelerations. The color wheel 1 may form part of a picture generation unit eg. a digital micromirror device. Motor 2 and position sensor 3 are shown. A protection ring (19, Fig 2b) may be arranged on the outer edge of the filter elements 12a-c.

Title: Front wheel stabiliser for four wheel drive vehicle
Inventor: JUNSO ICHIBA
IPC: B60G21/055
Filed: 1997-07-16
Abstract: The front wheel suspension arms 30 are supported by a suspension member 20 comprising a cross-member 20A and front/back (fore-and-aft) members 20B formed at the ends of the cross-member. A transfer 40 for distributing engine drive torque to the rear wheels is disposed underneath the cross-member 20A. A stabilizer 10 joining the suspension arms 30 is disposed such that it horizontally passes under the transfer 40 at the front of the cross-member 20A. Since the stabilizer 10 is not disposed at the rear of or above the cross-member 20A where it would tend to interfere with the vehicle body, the cross-sectional area of the cross-member 20A may easily be made sufficiently large. Also, by positioning the stabilizer 10 at the front of the cross-member 20A, the length of the arms 13 at both ends of the stabilizer can be made shorter, and desirable roll stability characteristics are obtained.

Title: Power supply with rechargeable battery and DC/DC converters
Inventor: LIM WAN-SOO
IPC: H02J7/00
Filed: 1997-12-03
Abstract: During a battery recharge mode an adapter 13 converts an external AC voltage into a DC voltage from which a DC/DC converter 20 provides a charging voltage for recharging a battery 12, and during an operational mode the battery 12 supplies a first load 30 via a DC/DC converter 10 and a second load 40 via the DC/DC converter 20. The DC/DC converter 20 thus has a dual role, whereby the number of DC/DC converters required can be reduced compared to a prior arrangement (Fig. 1). DC/DC converter 20 acts as a down-converter during the recharge mode and as an up-converter during the operational mode. During the recharge mode, current and voltage control signals are applied to the DC/DC converter 20 by a recharging control circuit 11 which senses battery voltage and current. A switch 80 allows the second load 40 to be powered via the DC/DC converter 10 during the recharge mode. During the operational mode switches 50 and 70 are closed and switches 60 and 80 are open, and during the recharge mode switches 60 and 80 are closed and switches 50 and 70 are open. The switches 50, 60, 70 and 80 may be controlled by a microprocessor according to activation/deactivation of AC/DC adapter 13. Altemativly, switches 60 and 80 may be NMOS transistors, and switches 50 and 70 may be PMOS transistors with gates driven directly by the output of adapter 13.

Title: Home stock control computer system
Inventor: GADD RICHARD JOHN
IPC: G06Q10/00
Filed: 1998-12-17
Abstract: A home stock control computer system (30) includes a memory for storing a current stock list based upon product codes. An electronic version of a store receipt (23), including product codes for items that have been purchased, is generated from previous purchases at the store (10) and is sent from the store's server (20) to the customer's home computer (30), where it is used to update the current stock list by addition of products purchased. Such a receipt may be sent via the Internet using a modem (33). Items are deleted from the current stock list as they are disposed of by the customer, in response to an electronic indication of corresponding product codes produced, for example, by scanning product packaging (35) with a bar code scanner (34). When the customer initiates a home stock check, the current stock list is compared with a predetermined stock level and an indication of which items need replacement is produced. This indication may be displayed (31), printed (32) or transmitted electronically to the store (36). If transmitted electronically such a list (36) may be used to automatically process the customer's order (22) ready for collection or delivery to the customer. The electronic purchase receipt (36) may also be used to generate an update of the correlation between products and their codes, which are administered from a central database (21), and which may take the form of updating bar codes or product descriptions, for example. Such updates are transmitted to the customer's computer (30) for updating a locally held product list.

Patent GB-2337634-A (GB)
Title: Making a MOS transistor having gate double sidewall spacers, e.g. for a DRAM
Inventor: YANG WON-SUK
IPC: H01L21/8238
Filed: 1999-04-23
Abstract: To make a MOS transistor, a gate electrode 102c is formed on a semiconductor substrate 100 and, using the electrode as a mask, ions of low concentration of a first conductivity type are implanted to form a first diffusion region 104c. First sidewall spacers 106c are then formed and, using the gate and first sidewall spacers as a mask, ions of low concentration of a second conductivity type are implanted to form a second diffusion region 110c. Second sidewall spacers 112c are then formed and, using the gate and first and second sidewall spacers as a mask, ions of high concentration of the second conductivity type can be implanted to form a third diffusion region 116c. Annealing of the substrate causes the diffusion regions to overlap such that the first diffusion region becomes a region of the second conductivity type. Such a construction suppress the short channel effect, prevents current leakage and reduces sheet resistance. The ions used may be As for the first diffusion region and B or BF 3  for the second and third diffusion region. The transistor formed may be a PMOS transistor in the peripheral circuit region of a DRAM, NMOS transistors being formed in the same process in the cell array and peripheral circuit regions. The NMOS transistors have single gate sidewall spacers, those in the cell array region being implanted with P and those in the peripheral circuit region being implanted with As and B or BF 3 . An insulating layer which forms the second sidewall spacers 112c may be left behind in the cell array region to act as an etching stop when contact holes are opened and to act as a barrier during a silicidation step.

Title: Board game
Inventor: GROVES WILLIAM MICHAEL
IPC: A63F3/02
Filed: 1999-05-04

The game is provided with two dice, playing pieces for up to six players, sets of chance cards, play money and items representing loot, the object being to move playing pieces around the board in accordance with rolling of one of the dice, to collect and exchange chance cards, and to acquire loot items bringing them home to a player's house area. The second of the dice is used in conjunction with a "police officer" playing piece, is only brought into play in certain circumstances, and acts as a block on the free movement of other playing pieces, when carrying items of loot, around the board.
Patent GB-2351620-A (GB)
Title: Triangle wave generator, current sensor, class D power amplifier, anti-hiss circuit and loudspeaker protection circuit
Inventor: RICHARD JAY PULHAM
IPC: H03K3/0231
Filed: 1999-07-01
Abstract: A triangle wave generator for use in a Class D amplifier is improved by use of logic gates IC4 at the output of the comparator IC3B. These sharpen the square wave edges and so improve triangle wave linearity. Excessive current in the amplifier transistor switches is detected by means of a printed circuit loop adjacent to a conductor supplying current to the amplifier (figures 7-11). The voltage induced in the loop by the varying current in the main conductor during the leading edge of a current pulse is integrated to give a measure of the pulse amplitude. The transistors are disabled if the current is excessive. The Class D amplifier may be used as an audio amplifier or as a DC-AC converter for providing 50 Hz mains power. If the amplifier is used in audio applications, the drive to the power output stage may be disabled if the input signal is very low or very high in order to reduce hiss and prevent loudspeaker damage.
