Patent GB-948441-A (GB)
Abstract: 948,441. Filter networks. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 20, 1960 [Jan. 20, 1959], No. 2111/60. Heading H3U. A four-terminal adjustable equalizer circuit arrangement for use with filters is formed as a bridged T-network with a series branch, shunting two series connected ohmic resistances Z, connected between one input terminal 1 and one output terminal 2, with a direct connection between the other input terminal 1<SP>1</SP> and the other output terminal 2<SP>1</SP> and with a parallel branch connected between said direct connection and the connection between the two resistances Z, one of the branches including a crystal Q, an inductance L and an adjustable capacitance C 1  connected in parallel and connected in series with an adjustable ohmic resistance R, and the other branch including a further crystal Q and an adjustable capacitance #C T  connected in parallel and connected in series with an adjustable inductance L, an adjustable ohmic resistance R being connected in parallel with the series arrangement. The arrangement shown in Fig. 1 is used to equalize the upper frequency part of the insertion loss characteristic of the pass band of the filter and at the same time to increase the attenuation at frequencies in a frequency band adjacent the upper frequency part, the elements of the series branch being so dimensioned that their lower parallel resonance frequency is at a frequency lower than the frequencies in the pass band and both their series resonance frequency and their upper parallel resonance frequency are at frequencies higher than the frequencies in the pass band, and the elements of the parallel branch being so dimensioned in dependence upon the dimensions of the elements in the series branch in accordance with the equation Z IN <SP>2</SP>=Z 1  - Z 2 , where Z IN  is the input impedance of the arrangement, Z 1  is the impedance of the series branch and Z 2  is the impedance of the parallel branch. The arrangement shown in Fig. 4, in which the positions of the series and parallel branches of Fig. 1 have been transposed, is used with a band pass filter or with a high pass filter for equalizing the lower frequency part of the pass frequency range, the circuit elements being so chosen that the arrangement has three resonance frequencies all of which are at frequencies lower than the pass frequencies.

Inventor: HIRAYAMA HIROKAZU
IPC: A01K89/01
Filed: 1995-03-04
Abstract: A spinning reel is provided with a reel body 2, a rotor 3 and a spool 4. The rotor 3 is supported on the front of the reel body 2 with freedom to rotate, and has a first arm portion 31 and a second arm portion 32 which are located facing each other such that the rotating spindle is interposed between them, a first bail support member 40 which is fitted to the tip of the first arm portion 31 and which has at its tip a line roller 41, a second bail support member 43 which is fitted to the tip of the second arm portion 32, and a bail 45. The spool 4 is located between the first arm portion 31 and the second arm portion 32. Further, the distance from the rotational axis X of the rotor 3 to the center of gravity of the second bail support member 43 is longer than the distance from the rotational axis X of the rotor 3 to the center of gravity of the first bail support member 40 including the line roller 41. Thus imbalance during rotation is suppressed without increasing the weight of the arm portion side opposite the arm on which the line roller is provided. <IMAGE>

IPC: H04M3/42
Filed: 1995-08-04
Abstract: An international prank phone call rejection system that can reduce the number of prank phone calls from overseas to be connected to international operators and reduce the workload on the operators. When an international incoming phone call is sent from an calling terminal (1) abroad, control part (11) in switchboard facility (7) refers to database part (12) to determine, based on the calling country code of the incoming phone call, whether said incoming phone call is from a prank phone call rejection country. If the call is from a prank phone call rejection country, an announcement for determining whether the call is a prank phone call is sent to the caller from speech answering part (8). If the caller provides a response to the announcement, speech recognition part (9) determines whether the response is valid, and, if valid, connects the call to switchboard (10) and, if invalid, determines the call to be a prank phone call and disconnects the call. <IMAGE>

Title: Pre-fracture laser formation of a notch in a connecting rod
Inventor: IKEDA HIDEAKI
IPC: F16C9/04
Filed: 1997-10-27
Abstract: A method of manufacturing a connecting rod comprises the steps of integrally forming a connecting rod blank from one piece, forming notches 12 with a laser along diametrically opposed regions of a inner wall of a crank opening 7 and then applying a force to the crank opening end to develop a crack radially form the notches by fracture and divide the crank opening end of the connecting rod into a saddle portion and a cap portion. The separating force may be applied by inserting a pair of spreading elements 13 into the crank opening 7, placing a wedge 14 between the elements and applying an impact point load to the centre of the wedge 14. The method may have an additional step, after the notches have been formed but before fracture, of finishing the cranking opening for roundness while the crank opening is experiencing a load the same as the load of a fastening force used to secure the connecting rod to a crank.

Filed: 1998-08-28
Abstract: A digital signal processor has ALUs 58, 72 and accumulating registers 64, 66, 76, 78 small in bit number. r-bit rounding bits are added to an N-bit data to be processed (wherein r<N) and g-bit guard bits are then added to the high order bits of the data, using bit alignment units 32, 34 and guard bit adder 38, each implemented with a wiring. Pre-multiplied, 2N data, 46, is also converted to N+r+g-bit data, using bit alignment/guard bit adder 50. The N+r+g-bit data is selectively operated by means of parallel accumulators 58, 64 and 66 and 72, 76 and; 78, and then selectively rounded and/or saturated by rounding/saturation processor 86. First and third, 32 and 82, and second and fourth, 34 and 84, bit alignment units, enable fixed-point and integer arithmetic to be performed respectively, by respectively aligning the data to the left and the right. Addition/subtraction arithmetic operations which include scaling can be performed by employing barrel shifter 60 in parallel with the accumulators. No rounding bits are used in one embodiment (fig. 7).

Title: Synchronising oscillators within a data communication system
Inventor: BENNETT RICHARD MICHAEL
IPC: H03J7/04
Filed: 1998-11-03
Abstract: In a data transmission system, pilot tones are inserted into the modulated baseband signal to assist in locking the receiver local oscillator 26 to the transmitter master clock 2. In the receiver, a circuit 24, e.g. a signal processor, identifies the pilot tones by looking for the known frequency difference between them. The circuit 24 samples the demodulated signal and makes a frequency shifted copy where the shift is equal to the expected separation between the pilot tones. The non-shifted and shifted signals are then combined in the frequency domain to reinforce one of the tones which is then searched for. Once the tone has been identified, a correction to the local oscillator frequency is calculated. The master oscillator may be synchronised to a plurality of remote units each including a respective local oscillator. Applications may be in a radio telemetry system e.g. for seismic data.
