Abstract: A cordless electrical appliance, for example an electric hot water jug, has a standard multi-pin type electrical connector on its appliance part and a cooperating connector on the base part. The pins of the appliance connector are oriented conventionally, namely generally horizontally as for a corded appliance, and are adapted to cooperate with shuttered spring terminals in the base connector, the arrangement being such that as the appliance part is lowered generally vertically onto the base part the horizontal pins on the appliance connector enter respective apertures in the base connector and displace the shutter thereby enabling the terminal ends of the spring terminals to move forwards into electrical contact with the ends of the pins on the appliance part. The use of a standard connector arrangement on the appliance part means that the appliance can be used in a corded or cordless manner and has cost advantages. A control on the appliance, eg. an element overtemperature protector on a hot water jug, can be arranged to prevent the base connector from coupling electrically to the base connector, and the base connector can advantageously comprise a unitary structure provided with its own cable clamp.

Abstract: An method for detecting a friction coefficient (µ) of the road surface according to the present invention comprises a detection step of detecting an operating angle (ϑ  H ) of the steering wheel (4) of the vehicle, a vehicle speed (V) and an operating pressure (Δ P) of the hydraulic power steering unit (1) for the front wheels (FW), and a calculation step of calculating the friction coefficient of the road surface on turning of the vehicle by considering relationships among a slip angle (ß f) of the front wheel, the friction coefficient of the road surface and a cornering force (C F ) of the front wheels. The method according to the present invention further includes a step of prohibiting the execution of the calculation step when the steering wheel is turned back, whereby the calculation step is executed only when the direction of the operating pressure of the power steering unit is in the equiphase with the operating direction of the steering wheel. Also, the four-wheel steering system according to the present invention has a rear steering actuator (11) for steering the rear wheels (RW) so as to increase the steering angle of the rear wheels as the friction coefficient of the road surface calculated by the above-described method decreases.

Abstract: A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes. The instruction set is limited to register-to-register operations and register load/store operations. Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions. The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes. By providing a conditional move instruction, many short branches can be eliminated altogether. A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken. Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like. The target can thus be prefetched before the actual address has been calculated and placed in a register. In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed. The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used. A granularity hint is added to the page table entry to define the page size for this entry. An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Abstract: A regenerative braking control system consumes energy generated in a period corresponding to an angle ϑ₁ which starts in a half of a period of an AC voltage produced in a drive motor during the braking of the drive motor. The regenerative braking control system also consumes energy generated in a period corresponding to an angle ϑ₂ that ends at the end of a half of a period of the AC voltage. The regenerative rate of braking control system utilizes a current induced in the driving coils of the drive motor at the end of the period corresponding to the angle ϑ₁ to recharge a battery. By utilizing two periods to carry out the regenerative braking process, the recharging energy and the braking force can be controlled individually. Moreover, a controller monitors the electric control system to determine whether a malfunction is present. If a malfunction is detected, an electrical brake electrically brakes the drive motor. This electrical braking after the detection of a malfunction in the electrical system provides satisfactory controllability of the electric vehicle.

Abstract: The inventions relate to methods for the production of wooden hollow beams (50) and forms of this beam. Serving as feed stock are round-timber outer parts/slabs from medium and thick round-timber diameters as well as segments/halved timber from the small-timber range. The feed stock/raw material (5) similar to halved timber is preferably profiled conically on three sides in the wet state and is slit (12) to protect against stress/drying cracks. After the drying the polygonal finish profiling is effected and so too is the severing into individual elements (21), the conversions of which lead to a wooden beam (50) with outer solid-timber character and inner hole (51) (wooden hollow beam), or the severing is effected during or after the formation of layers, and composite materials (74, 75, 76) can be embedded in the hollow wooden beams (50) in the most varied processing operations. Similarly, the procedure/method according to the invention takes place to utilise wedge-shaped round-timber centre pieces (3) - as are obtained when sawing parallel to the fibres; or the assembly of only two parts to make "superimposed" ceiling joists/trusses.

Abstract: A track cross signal generation circuit comprises a tracking error signal generation circuit (14), an offset compensation circuit (16), a level setting circuit (22), and a comparator (24). The comparator (24) directly receives a tracking error signal (TES) output from the tracking error signal generation circuit (14) without passing through the offset compensation circuit (16) and a reference level (Vref) output from the level setting circuit (22). Further, the comparator (24) compares the tracking error signal (TES) with the reference level (Vref), and generates a track cross signal (TZC) representing the tracks formed on an optical recording medium (12) crossed by a beam. Namely, the gain of the tracking error signal (TES) is not affected by the offset compensation circuit (16) even within a high-speed region of the beam. Consequently, the track zero cross signal (TZC) correctly indicates tracks crossed by the beam, and correctly and stably carries out a seek operation in the high-speed region of the beam.

Abstract: A process for mapping high resolution data into lower resolution data involves the use of a hysteresis loop. A transparent digitizer (22) is disposed above a liquid crystal display (24). As an operator writes on the digitizer (22) with a stylus (26), the writing is digitized to form high resolution data which is converted to lower resolution data utilized to operate the display (24). Distortion resulting from the conversion is minimized by using a hysteresis loop concept wherein change of the lower resolution data is prevented unless there is at least a given minimum change in the high resolution data, the value of the lower resolution data also depending on whether the high resolution data is increasing or decreasing in value.
