Patent GB-2274819-A (GB)
Title: Variable ratio steering system.
Inventor: SHIMIZU YASUO
IPC: B62D1/16
Filed: 1994-02-08
Abstract: A first shaft (11) on an input end and a second shaft (18) on an output end are supported in a mutually parallel and laterally moveable relationship, and a crank pin (17) extending from the second shaft is engaged in a diagonal slot (16) provided in an associated axial end of the first shaft (11). Because the radial distances of the point of engagement between the first and second shafts as measured from the axial center lines of the first and second shafts generally differ from each other, there is a non linear relationship between the angular displacements of the first (11) and second (19) shafts. In particular, the angular increment of the second shaft (19) for a given angular increment of the first shaft (11) may be progressively reduced as the angular displacement of the first shaft (11) is increased, and by suitably varying the eccentricity between the two shafts eg by motor 31 it is possible to require only a relatively small steering input angle for an improved maneuverability at low speed, and to prevent over-sensitive behavior of the vehicle for an improved stability at high speed. <IMAGE>

Title: Output drivers in high frequency circuits
Inventor: RAJE PRASAD A
IPC: H03K19/0175
Filed: 1994-04-05
Abstract: A high frequency circuit 100 has an output driver 102 including pull-up and pull down circuits 114, 116 and a tri-state section 118 connected to an output transmission line 106. A further driver 104 having pull-up and pull-down circuits and a tri-state section 118 may be provided. Each tri-state section 118 has a low impedance and a high impedance state. Its low impedance state serves to match the impedance of the output transmission line 106. Its high impedance state isolates its driver 102 from the output transmission line 106. Repeat pull-up, pull-down circuits may be coupled to the tri-state section 118 by a bipolar (316, Fig 3), FET (306) pull-up, pull-down circuit or a bipolar (406, Fig 4), bipolar (418) pull-up, pull-down circuit. Three output drivers (502, 504, 506, Fig 5) may be coupled to three transmission lines (516, 512, 514). Integrated circuit techniques may be used for the drivers and for the transmission lines. <IMAGE>

Title: Fault diagnosis of exhaust gas recirculation device in diesel engine
Inventor: MIWA HIROMICHI
IPC: F02M25/07
Filed: 1997-11-12
Abstract: A diagnostic device for a diesel engine comprises an airflow meter 12 at the intake to the engine. A control unit 10 predicts an intake pressure and an exhaust pressure of the engine from the fresh air flow-rate and engine rotation speed from sensor 13. Faults in exhaust gas recirculation (EGR) system 6, 7, 8, controlled by control unit 10 are diagnosed based on at least one of the predicted intake pressure and exhaust pressure. Preferably fault diagnosis is based on a differential pressure between the intake pressure and exhaust pressure, or on a comparison of an estimated EGR rate and target EGR rate found from the intake pressure and exhaust pressure. The system does not require the provision of any special sensors. Smoke emission is also reduced by limiting the maximum fuel injection amount of the engine.

Title: Variable length coding with code word length detection
Inventor: NAM SEUNG-HYUN
IPC: H03M7/40
Filed: 1997-12-08
Abstract: The invention relates to a coding apparatus which detects the length of a variable-length code word using a Huffman code tree. Symbols to be coded are inputted to a code-book memory which generates a corresponding fixed-length code containing a variable-length code word. Each bit of a generated code word is successively selected, and for each bit, the number of terminal nodes at a corresponding level in a Huffman code tree is found. The boundary between the variable-length code and stuffing bits is calculated, and on the basis of this, the length of the variable-length code within the fixed length codeword is deduced. The coding apparatus avoids the need to memorize the length information of variable-length codes.

Filed: 1998-01-08
Abstract: The leg section 4 of a surgical operating table has two pins 44 and 45 projecting from its end face 43, which engage respective sockets 5 and 6 in an end face 3 of the trunk section 1. One pin 44 is fixed and has a step 50 engaged by a locking peg 8 in the socket 5. The pin 44 carries a tapered sleeve 56, which is slidable rearwardly against the action of a spring 55 when it engages the mouth of the socket 5. The other pin 45 is shorter and is itself slidable rearwardly against the action of a spring 59, the pin having a tapered surface 46, which engages the mouth of the other socket 6. Engagement of the slidable tapered surfaces on the two pins 44 and 45 with the mouths of the sockets 5 and 6 prevents lateral displacement of the leg section 4 relative to the trunk section 1.
