Title: Polygon data converter, three-dimensional simulator and polygon data conversion method
Inventor: TAKEDA MASAKI
IPC: A63F13/245
Filed: 1995-06-16
Abstract: It is an object of the invention to provide a polygon data convertor capable of effectively utilizing hardware incapable of plotting a back polygon, etc., a three-dimensional simulator, and so forth. A coordinated inversion portion (410) executes right-and-left inversion processing of apex coordinates of an input polygon on the basis of a right-and-left inversion flag and an up-and-down inversion flag. A back-and-front judgement portion (408) examines allocation sequence of the apex number and judges the back and the front of the input polygon. An allocation sequence replacement portion (42) replaces the allocation sequence on the basis of an exclusive OR of the back judgement flag, the right-and-left inversion flag and the up-and-down inversion flag, and an apex number allocation portion (422) allocates the apex number of the original input polygon to the divided polygons in accordance with the allocation sequence so replaced. The apex coordinates, the inversion apex coordinates, etc., of the polygon are read out from a data memory (412) in accordance with this apex number. <IMAGE>

Inventor: PATEL PRAKASH
IPC: C07D487/22
Filed: 1996-05-18
Abstract: A single stage process is provided for the preparation of axially substituted tetraazaporphins by the reaction of a compound of the formula: LW n X (v-n) wherein W is the axial substituent; L is an element which has a valency > 3;X is H,-OH or halogen; v is the valency of the element L; and n is an integer from 1 to (v-2); with a diiminoisoindoline or 1,2-dicyanobenzene. The process is particularly useful for the preparation of axially substituted silicon tetraazaporphins in which the axial substituents are alkoxy groups. Exemplified is the preparation of bis (n-butoxy) silicon phthalocyanine. Diminoisoindoline was reacted with bis (n-butoxy) dichlorosilane in tetramethylene sulphane at 30-40{c ; diazabicycloundecene was added and the reaction continued at 90-100{c, and a pale blue solid was obtained by addition of ice and water.

Title: Electrodeless fluorescent lamp
Inventor: GIRACH MAHOMED HANIF
IPC: H01J65/04
Filed: 1996-06-26
Abstract: To retain a discharge vessel 1, a notch or groove 12 is formed in a re-entrant portion 3 of the vessel.

IPC: H04W84/02
Filed: 1996-08-14
Abstract: A high-gain amplifier circuit that can start the normal operation quickly after a power supply is turned on includes first to n-th differential amplifiers (101-103) cascade-connected at first to n-th stages, input terminals (111,112) to which an input signal is applied, a first output terminal (113) from which a first output signal is derived, a second output terminal (114) from which a second output signal is derived, and a voltage/current converter (104-107) applied with the first and second output signals and producing an output current corresponding to an offset between bias components of the first and second output signals. The output current of the voltage/current converter is fed back to the first differential amplifier at the first stage, thereby canceling the offset between the bias components of the first and second output signals. This circuit is applicable to an amplitude limiter for limiting the amplitude of a received signal in a selective-calling radio receiver.

Title: Window stay with cam adjuster to compensate for window seal wear
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/30
Filed: 1997-05-15
Abstract: A window friction stay has a track 10 to be fixed to a window frame and a member 16 of a link arrangement to be attached to the window sash. The link arrangement is connected to a slider 24 in the track and has a member 18 pivotally mounted on the track. An intermediate component has a head part and a cam part locating closely within a hole in the pivot member 18, the axis of the cam part being offset in relation to the axis of a through opening in a component 50. A fixing screw 48 extends through the opening in the component, through the hole in the pivot member, and through a hole in the track to engage in a securing nut. Manual rotation of the component by way of the head part thereof obliges the pivot member to move further towards an end member 32 in the track, leading to increased pressure on an end face 60 on the member against a cam surface of the end member, and therefore additional pressure of the window against the window frame to improve sealing.

Title: Data network router
Inventor: MAUGER ROY HAROLD
IPC: H04L12/70
Filed: 1997-12-01
Abstract: In a broad band network comprising a plurality of edge switches interconnected by a plurality of tandem switches, IP packet data is routed by determining from each packet whether that packet forms part of a flow of packets. Where a packet is determined to be part of a flow, it is segmented into minicells for transmission over a permanent virtual channel established across the network for that flow. Where a packet is not determined to be part of a flow, a destination edge switch is identified for that packet which is then transported to that edge switch via a default permanent virtual channel. Permanent virtual channels for new flows are established at the network periphery by defining a succession of nodes and virtual channels (VCs) to be used to reach the destination of that flow.

Title: Pseudo duplex digital radio
Inventor: GIBBS JONATHAN ALASTAIR
IPC: H04B7/26
Filed: 1999-06-30
Abstract: A digital radio operating in time division duplex is in communication with a second digital radio over a single radio channel. Control of the radio channel may reside with either radio. However authority for a radio to change the frame format in order to increase the proportion of time for which it transmits always resides with the radio transmitting the least per frame, which is also the radio which transmits first in each frame. This arrangement allows rapid response to the need for a radio to switch from listening to speaking mode thereby reducing speech clipping. When the two digital radios are transmitting for equal proportions of the frame, authority to change the frame format passes to the radio that is transmitting at that instant.
