Patent GB-2317718-A (GB)
Title: Reference current circuit and reference voltage circuit
Inventor: KIMURA KATSUIJI
IPC: G05F3/30
Filed: 1994-12-07
Abstract: A reference current circuit (figure 8) or reference voltage circuit prevents the occurrence of the difference collector current associated with the Early Voltage Effect. The circuit comprises transistors Q1, Q2, Q5, Q6 with the emitter area of Q2 being 'e' times that of Q1, Q5 and Q6, where 'e' is the base of natural logarithms, the overall effect of this being that the collector currents of Q1 and Q2 are equal to each other. A similar result may be obtained by using MOS transistors (figures 17 and 18) where the transconductance of one transistor (M2, figures 17 and 18) is four times as large as the transconductance of the others. There is a resistor R1 between the collector and base of Q1. Additionally the circuit includes transistors Q7 and Q8, and a resistor R5 connected between the base of Q1 and the collector Q6. In the voltage circuit, an output terminal T3 is connected to the node between resistor R5 and the collector Q6.

Title: Self-steering wheel assembly
Inventor: RODGERS PETER
IPC: B60P3/12
Filed: 1998-02-13
Abstract: A self steering wheel assembly for a trailer 18 having a tube 12 on which is mounted a wheel 11, the tube having an angled upper end 14 and a king pin 15 secured to the wheel 11 via tube 12. A second tube 16 fixed to the trailer 18 is rotatably mounted to the king pin 15 and has a lower angled end 17 which abuts the end 14 of tube 12. When the wheel is steered as the result of the forces generated by the steering of the towing vehicle, the tube 12 rotates such that point 26 on end 14 of the tube 12 moves along the inclined face 17 of tube 16 forcing the tube 16 and thus the trailer body 18, to rise in direction 26. Once the turn is complete the weight of the trailer 18 forces the tubes 12, 16 and king pin 15 to assume their original positions. The trailer 18 may be used to recover a broken-down or damaged car or motor cycle (Figs. 3 to 7) and be readily collapsable for stowage.

Title: Collapsible ladder
Inventor: SCHMITZ HANS JUERGEN
IPC: B63B27/14
Filed: 1998-12-09
Abstract: A collapsible, flexible ladder comprises rigid runged sections engageable end-to-end to form a substantially rigid structure and a rope which extends along the length of the ladder. Lateral tubes (1) fit together in an end-to-end relationship to form the stringers or stiles of the ladder. Each tube has a tapered recess (2) at one end and a tapered cone at the other which permit interlocking (4) of individual runged sections and which act as rope guides (5) within the tubes. Soft-rated, plastic-sleeved coil springs (6) sit between the runged sections. A ratchet-driven tensioning system (8) is used to put tension on the ropes. These ladders may be stored in a rolled up condition or linked laterally to similar ladders to form ladder matting.

Title: High frequency intergrated circuit for high-frequency radio transmitter-receiver suppressed in influence of high-frequency power leakage
Inventor: YAMAMOTO KAZUYA
IPC: H03G3/20
Filed: 1996-08-05
Abstract: A low-pass filter (3;3a, 3b; 8:13; 14) which only passes signals in a band lower than that of high-frequency signal components is provided between a high-frequency signal processing circuit (2; PAi) which processes the high-power signal of an RF front end section (RFFP) for processing the high-frequency signal of a portable telephone set and a control circuit (1: GVC) which controls the operation of the circuit (2). The circuit (2) functions as the transmission/reception switching circuit (2) of the telephone set and the circuit (1) functions as the transmission/reception control circuit (1) which determines the operation mode of the circuit (2). Alternatively, the circuit (2) functions as a power amplifier (PAi) and the control circuit (1) functions as the gate voltage control circuit (GVC) which adjusts the gain of the amplifier (PAi). Therefore, the influence of leakage of high-frequency components from the gate of a field effect transistor is suppressed, and the RF front end section (RRFP) can be constituted of a chip occupying a small area.

Title: Information duplicate distribution over a network
Inventor: NISHINA TOSHIHIDE
IPC: G06F17/30
Filed: 1995-04-18
Abstract: When definition information required for communication over a network is distributed to other information processing units that are connected to the network, if this information is modified, this modification is relayed to the other information processing units, the contents of this modification are managed by a management list, and the differential between the information before said modification and the information after said modification is extracted by a differential extraction means and then transmitted. Transmission is executed to the partner in order from the definition information of the unit close to the side of transmission according to the positional relationship as seen from the side of transmission. At this time, the relay prompt information that prompts the relay of the modified information and the definition information that is to be transmitted are coupled into one data set, and then transmitted. Although verification and recording of the information being received are executed sequentially in the relay of the definition information, the subsequently received information is verified at the same time as the previously received information is being recorded.

Abstract: Remote control of power devices is described e.g. electric bulbs of lighting installations, by use of any remote control transmitter, primarily designed for an audio-video equipment. An infrared signal transmission method is used and in order to control a power receiver the signal derived from an infrared transmitter is used with discretionary ways of modulation. The signal is reproduced in the shape of a string of impulses (logical "zero", logical "one") and its duration is proportional to the duration of a signal excitation source of a guiding transmitter. The circuitry, is characterized by an impulse-forming circuit (Ufl) connected to an infrared sensor (CP) and to input and delay counter (UZWOC) and furthermore, to a control signal forming system (UTSS). Signal forming circuitry (UTSS) through the intermediate circuit (UP) is connected to phase shift circuitry (UPF) and to a further sensor (S). <IMAGE>
