Patent GB-2362654-A (GB)
Title: Diamond saw blade
Inventor: RUNYON ROBERT CARROL
IPC: B23D65/00
Filed: 2001-05-24
Abstract: An electro-deposited nickel diamond dicing saw blade is made by depositing nickel in the presence of free diamonds which are encapsulated in a plating matrix of preferably nickel on a masked base. When making a blade using a prefabricated hub, the blade is deposited directly on a portion of the hub. When making a blade that is hubless, a blade is deposited on an unmasked portion of a flat sheet such as stainless steel. After plating the diamond dicing saw blade to a desired thickness the first plated side is smooth and the opposite side comprises exposed diamonds. The exposed diamonds are encapsulated by plating a matrix of nickel alone so as to equalize the exposed encapsulated diamonds on both sides of the saw blade. A subsequent operation of neutralizing or etching as least the smooth side of the diamond dicing saw blade is performed to leave an equal amount of exposed diamonds on both sides of the saw blades substantially completes the operation of the saw blade. Subsequent operations by the manufacturer or the customer include dressing the outside diameter of the saw blade to an exact eccentricity on the saw spindle, thus, grinding the blade to an exact dimension usually is not required during manufacture of the saw blade. The diamond saw blade is produced by the steps of providing a metallic base on which to plate a diamond saw blade, masking a portion of the base to prevent plating thereon, plating a holding matrix onto the base in the presence of free diamonds to form a diamond saw blade with diamonds encapsulated in the matrix leaving a smooth base side with no exposed diamonds and an exposed side with portions of diamond exposed, plating the exposed side with holding matrix material to substantially cover the exposed diamonds, and removing e.g by etching holding matrix material from at least the smooth base side to provide a diamond saw blade having exposed diamonds on both sides of the saw blade.

Title: Liquid crystal display for equivalent resistance wiring
Inventor: KIM HONG JIN
IPC: G02F1/1362

Abstract: A liquid crystal display having a pad member 40 for compensating for differences in resistance in electrical conductors 23. A pad member in contact with a driving circuit includes a transparent electrode 28 having a length that depends on the length of an associated electrical conductor 23 that is connected between the pad member and a corresponding signal line at a pixel area on which a plurality of liquid crystal cells are arranged. Accordingly resistance differences that depend on the length of the electrical conductors 23 are compensated for, thereby making signal conductors with substantially equal resistances. Resistance differences can be compensated for by employing any of the following techniques; having a length or width of either the transparent electrode 28, or the electrode pad 16, that depends on the length of an associated electrical conductor 23; having the conductivity of either the transparent electrode 28 or the electrode pad 16 depend on the length of an associated electrical conductor 23; having the width of the electrical conductor 23 depend on its length; having the size or conductivity of a compensating pattern applied to the electrical conductor 23 depend on its length.

Title: I.c. engine fuel injection system with plunger-type solenoid valve
Inventor: RODRIGUEZ-AMAYA NESTOR
IPC: F02M59/46
Filed: 2001-07-31
Abstract: The fuel injection system comprises a high-pressure injection pump 11, which is supplied with fuel from a low-pressure region, and a plunger-type solenoid valve 22 which controls the injection pump 11. The valve 22 has a housing with an armature chamber 31 and two chambers 27,33 which are disposed coaxially and are connected by a valve opening but separable by a valve seat. The armature chamber 31 is connected by a pressure passage 21 to the inlet side and the low-pressure valve chamber 33 is connected to the outlet region of the injection pump 11. The low-pressure valve chamber 33 has a fuel inlet passage 32 and a fuel outlet passage 35. According to the invention, each passage 32,35 has a reduced cross-section where it joins the low-pressure valve chamber 33 in order to reduce cavitation, and hence erosion, in the region of the low-pressure valve chamber 33. The change in diameter of each fuel passage 32,35 may occur in a single stage or in multiple stages.

Title: Replacing intra-coded frame(s) with frame(s) predicted from the first intra-coded frame
Inventor: LALLET ARTHUR
IPC: H04N7/26
Filed: 2001-08-08
Abstract: A method of communicating video or image data in intra-coded and predicted frames includes generating a sequence of video or image frames, including intra-coded frames interspersed by predicted frames of a video or image stream (690), including a first intra-coded frame. The method includes the steps of transcoding at least one intra-coded frame I<SB>4</SB> subsequent to the first intra-coded frame into at least one predicted intra-coded frame P'<SB>4</SB>, thereby forming a modified sequence of video or image frames, wherein the at least one predicted intra-coded frame is predicted from said first intra-coded frame; and communicating said modified sequence of video or image frames including the at least one predicted intra-coded frame in place of the at least one intra-coded frame from which the at least one predicted intra-coded frame was transcoded. Alternatively a first predicted intra-coded frame may be generated from the first intra-coded frame, and subsequent predicted intra-coded frames generated from previous predicted intra-coded frames (fig 13). In this manner, fewer intra-coded frames are sent over for example, an IP network, thereby saving bandwidth usage over traditional methods, with minimal loss of quality of the video signal. The invention finds particular application in video conferencing.

Title: Portable telephone and data communication control method which detects presence of object causing deterioration in antenna efficiency
Inventor: ASADA HIDEAKI
IPC: H04M1/72505
Filed: 2001-11-29
Abstract: A portable telephone includes a speech transmission circuit 13, a data transmission circuit 12, an earphone/microphone detection circuit 4, and a control circuit 11. The speech transmission circuit performs speech communication through an antenna 6. The data transmission circuit performs data communication through the antenna simultaneously with speech communication by the speech transmission circuit. The earphone/microphone detection circuit detects whether the earphone/microphone is in use, indicating the absence or presence of an obstacle (namely the head of the user) that causes deterioration in the transmission efficiency of the antenna. When one of a data communication request during speech communication and a speech communication request during data communication is generated, the control circuit 11 determines on the basis of a detection result obtained by the detection circuit whether to permit/reject the request. As alternatives to detecting the presence of the earphone/microphone, in other embodiments the amplitude of the output of a microphone may be detected (8; Fig. 2) or a distance sensor may be provided (9; Fig. 3).

Title: Servo controller and method
Inventor: TSUTSUI KAZUHIKO
IPC: H02P29/00
Filed: 2000-11-01
Abstract: The variation of the correction effect due to variation with time of friction and the difference of machining conditions is suppressed by calculating an ideal position based on an ideal servo system model, multiplying the difference between the calculated ideal position and an actual position feedback by a specified gain only for a specified time after the direction of the ideal position is reversed, and adding the result, as a correction, to a speed command. Even in a mechanical system where the torsion of a ball screw and the elastic variation of a sealing material are greate, biting due to back torsion after correction is suppressed and a servo system is prevented from being unstable.

Inventor: YORK MICHAEL T
IPC: H02K1/24
Filed: 2003-11-21
Abstract: An alternator rotor prevents the field coil from moving within the rotor assembly in a manner that increases the power density of the alternator. The structure maximizes the available space for the field coil and provides increased dissipation of heat to accomplish the same. Preferably, the outer diameter of the field coil is greater than or equal to the inner diameter of the first and second pole pieces for frictional engagement of the coil assembly to the first and second pole pieces.
