Abstract: The invention relates to running gear for railway vehicles having a low-lying loading bridge, consisting of at least two sets (4) of wheels with a small axle base and a running gear frame consisting of lateral faces (1) and crossmembers (2) between two axles in each case, the sets (4) of wheels being braced in the running gear frame via the axle bearings (3), and the running gear being connected with false pivot to the vehicle frame solely via a bearing leaf spring (10) and a shackle suspension (11), each lying laterally lengthwise. 
<??>The object of the invention was to improve the rolling characteristics in this running gear, to optimise the running behaviour on straight track and in bends with the arrangement of the required transverse clearance of the running gear and to make it more favourable by the use of long shackles. The power transmission from the loading bridge via the bearing leaf spring (10) into the running gear was to be improved. 
<??>This object is achieved by the fact that the bearing leaf springs (10) are arranged on spring brackets (5) arranged on the outside on the lateral faces (1) of the running gear frame laterally between the clearance gauge (6) and the loading space (8) of the vehicle and above the wheels.

Abstract: 1. A method for automatically matching the unknown impedance of an antenna to the known nominal impedance of a transmitter using a matching network having variable impedance and which is connected on the input side via a measuring head to the transmitter output and on the output side to the antenna, which network also has at least one input-side capacitive shunt arm with a variable capacitance, consisting for example of a plurality of capacitor elements which can be switched in parallel to one another and has an inductive series arm with a variable inductance consisting, for example, of a plurality of coil elements which can be switched in series to one another, which network in addition for setting its variable impedance by changing the capacitance of the capacitive shunt arm and/or the inductance in the inductive series arm cooperates with a micro-processor which controls, in dependence on the information transferred to it on the input side by the measuring head, in particular relating to the voltage standing wave ratio (VSWR) and the phase relation, the impedance setting of the matching network in the desired direction, characterized in that, to perform a standard tuning process (STA), the transformed antenna impedance presented to the transmitter output via the matching network (AN) assumes an inductive value in a first step by changing the inductance in the inductive series arm and, relative to the Smith diagram, reaches the "G= 1" circle, in that, in a second step, by changing the capacitance in the capacitive shunt arm the transformed antenna impedance is moved along the "G= 1" circle (G= 1) until the measuring head (MK) indicates the transition from the inductive zone to the capacitive zone and thus the tuning process is concluded in that, however, if the transformed antenna impedance indicates an excessively high voltage standing wave ratio, approximately VSWR > 3 when the "G= 1" circle is reached, an intermediate step is performed in the course of the second step when a predetermined voltage standing wave ratio, approximately VSWR= 3, is reached, in which second step the transformed impedance of the antenna is corrected, by further changing the inductance in the inductive series arm, in the direction of its displacement to the "G = 1" circle and in that for the completion of these process steps, the measuring head is designed in terms of circuitry to issue control information to the micro-processor (MP) in such a way that these items of control information have, in addition to information relating to the transmitting level (P), Phase (Ph) and voltage threshold ratios (VSWR) < 1,5 ; VSWR > 3), also a criterion for the "G = 1" circle (G = 1).

Abstract: ABSTRACT A linear motion ball bearing is disclosed for providing relative linear motion in combination with a shaft.   A housing has an axially elongated opening therethrough and an axially elongated generally tubular shaped ball retainer is positioned within the housing opening and defines a plurality of endless ball loops therein extending generally in the axial direction of the retainer.  The retainer has a radially inner surface and a radially outer surface and the ball loops are spaced generally circumferentially about the retainer.  Each loop contains a plurality of balls and has a first ball duct for a row of loaded balls and a second ball duct for a row of unloaded balls.  Each first ball duct is open through the radially inner and radially outer surfaces of the cage, and each ball loop is arranged with the first ball duct next adjacent the first ball duct in the adjacent ball loop along one axially extending side and the second ball duct wherein adjacent the second ball duct in the next adjacent ball loop along the other axially extending side.  The housing defines a land opposite each pair of adjacent first ball ducts and extending radially inward, each land extending sufficiently radially inward and being of sufficient circumferential dimension to support the loaded balls of adjacent pairs of the first ball ducts and having a contoured relatively smooth surface for accommodating the loaded balls positioned within the corresponding opposed pair of respective first ball ducts of respectively adjacent ball loops.  A uniquely shaped complex ball support surface connects each pair of ball ducts while maintaining constant floor to ceiling height about the balls to provide smooth, quiet operation of the bearing so as to combine with the uniform loaded ball arrangement to provide a unique bearing having improved load life performance and substantially quiet characteristics, while simplifying the manufacturing procedures.

Title: Destuffing control by modifying detected pointer with differential value
Inventor: KANEKO HIROAKI
IPC: H04J3/07
Filed: 1992-04-24
Granted: 1997-02-25
Abstract: In a digital communication system where a received stuff-synchronized TDM signal is demultiplexed into data signals each containing a sequence of frames. Each frame contains a pointer to indicate the start timing of the frame and specify positive, negative or zero destuffing. A pointer is detected from each data signal and compared with a previous pointer of the data signal stored in a memory. From this comparison the type of destuffing to be performed on a frame is determined, and in response to it, +1, -1 or 0 is added to the previous pointer to produce a current pointer, which is then used to rewrite the previous point. A binary clock count value is generated by a single phase counter and compared with the current pointer to generate a start-of-frame signal if it equals the current value.

Granted: 1996-10-15
Abstract: An analysis-by-synthesis speech coder is pro-vided, in which the filter for the spectral weighting of the error signal exploits a more precise human perception model than is conventionally used; thereby resulting in a quality enhanced synthesized speech signal. The weighting filter has a transfer function in which the modulus is represented by the inverse of a global masking threshold of the noise by the speech signal. The thresholds indicate, for the different frequencies in the speech signal, the maximum amount of noise the human ear can tolerate.

Abstract: In a system for controlling a gear ratio of a multi-step geared or continuously variable automatic transmission of a vehicle based on determined parameter indicative of operating condition of the vehicle including a driving resistance, the driving resistance is calculated in an equation in which motive force - driving resistance =  vehicle mass x acceleration using the law of motion. In the first embodiment, the calculation is carried out, without using a torque sensor, by applying an adjustment for torque consumption by a device such as an air conditioner and a torque loss caused by braking. In the second and third embodiments, the driving resistance is calculated using a torque sensor. Thus, with the arrangement, the driving resistance can be accurately determined applying appropriate adjustment, a gear ratio to be shifted is properly determined in any traveling condition including hill climbing.
