A retaining strap (35) engages round the extension (25) of the actuating mechanism (1), the transverse flange (36) of the retaining strap (35) having a rigid securing web (37) and a catch web (38). The securing web (37) bears on the end face (43) of a transverse-web prolongation (12), and the catch web (38) engages resiliently with its catch nose (39) under this transverse-web prolongation (12). <IMAGE>

Abstract: An inductive pen (16) repetitively transmits pulses of an oscillatory signal having a characteristic frequency. Pen state information, such as pen tip contact switch information, are encoded by a number of techniques. These techniques include pulse width modulation or pulse position modulation, so as to convey pen state information to a digitizing tablet (10) in a manner that does not adversely affect pen position determinations. The pen state information may also be encoded on the oscillating signal by Frequency Shift Keying (FSK), Phase Shift Keying (PSK), or Amplitude Modulation (AM). A digitizer tablet (10) includes circuitry for detecting the transmitted pen state information, the circuitry accommodating the selected modulation scheme. The tablet (10) is responsive to the transmitted pulses for placing tablet circuitry in a low-power consumption state between pulses so as to conserve tablet power.

Abstract: A semiconductor integrated circuit for image processing includes a playback luminance signal processing circuit, a playback chromatic signal pro - cessing circuit for receiving a recorded image signal, and a TV system conversion circuit for selectively converting a TV system to a different one. The chromatic signal played back is recorded. In another embodiment, the integrated circuit includes a playback luminance signal processing circuit for re - ceiving an image signal for television, a TV system conversion circuit for selectively converting a TV system to a different one, and a recording chromatic signal processing circuit for receiving the output signal of the TV system conversion circuit. 
     Since the semiconductor integrated circuit is arranged so as to perform the process of not solely playing back or recording an image signal but also converting the system, a synchronizing signal necessary for playback processing and a color subcarrier generating circuit necessary for system conver - sion can be put to common use. Therefore, accurate signal processing is made possible with simplicity in construction.

Abstract: An analog to digital converter circuit and technique including a peak detector circuit (300) for generating a reference potential corresponding to a peak amplitude of the analog signal to be converted, a level shifting circuit (100) for shifting the dc level of the analog signal in response to the reference potential, and an analog to digital converter (201) for converting the shifted analog signal relative to the reference potential to provide automatically high bit resolution digital signals, independent of the magnitude of the input signal. Preferably, the level shifter sums one half the analog signal and one half the reference potential to produce the shifted signal, and the shifted signal is converted using a ratiometric analog to digital converter having a reference signal input of one half the reference potential. The reference potential is periodically updated by detecting a new peak. Analog signals containing amplitude modulated information may be so processed to provide effectively a dynamic range corresponding to the input range of the analog to digital converter for optimum bit resolution.

Abstract: Prior-art telecommunication systems comprise transceiver arrangements structured, for example, as optocouplers for optically transmitting information, that is in a DC isolated manner. These optocouplers which may transfer relatively high frequency signals are expensive. When the signal to be transmitted has a low maximum frequency of about 200 Hz, a more cost-effective transceiver arrangement may be used, which comprises a transmitter means arranged for effecting a change of ambient temperature (a power dissipating resistor) and comprises a receiver means arranged for detecting the change of ambient temperature (an NTC resistor or a semiconductor element). In an advantageous embodiment transmitter means and receiver means are used in integrated form deposited each on either side of a substrate.

Filed: 1992-01-10
Abstract: In order to control a voltage using e.g. a tap transformer (5000), the difference V between the actual voltage (V) and a reference voltage (110) is obtained (120) and integrated over time (130). That integral is then modified by at least one parameter generated by fuzzy logic (3000) from control conditions of the voltage. In this way the fuzzy logic (3000) may find the optimum control strategy which keeps the actual voltage closest to the reference voltage without an excessive number of tap position changes. The reference voltage (110) may vary with time, and therefore the control of the voltage with time may be evaluated (2000), and the control conditions varied accordingly, e.g. by fuzzy logic so that the control arrangement can exhibit learning. Normally, the integral is modified by such that       ∫ΔVdt ≧ B          when B is the parameter determined by the fuzzy logic (3000), but other control strategies may be used. The present invention is also applicable to control of reactive power.

Abstract: A valveless positive displacement pump (60) including a closed end cylinder (84) having two fluid inlet and outlet ports (90, 92) adjacent the closed end. A piston (122) reciprocably and rotatably driven in the cylinder and including a reduced area portion (128) on one free end which communicates cyclically with the inlet and outlet ports to pump fluid through the positive displacement pump. The piston reduced area is a reduced radius portion to minimize air bubble buildup and to minimize fluid volume at the end of the piston stroke. The piston also has a gland area formed (130) in the piston which cyclically communicates with a pair of ports to clean the piston and cylinder and prevent the buildup of solids. The piston and cylinder can be formed from a hard ceramic material for accuracy and wear resistance. The cylinder is closed by a resilient end cap (88, 88′, 88˝, 174, 178) to relieve pressures caused by piston movement when the inlet and outlet ports are closed. The piston is driven by a compliant ball support (104) including a ball (112) and socket biased between the piston and drive shaft to self adjust and compensate for misalignment of the pump. The angle between the drive shaft and the piston is variable to vary the fluid volume and aligned so that the end clearance between the piston and cylinder does not change as the angle is changed.
