Abstract: A numerical controller for a grinding machine, wherein one of reference sizing points is selected according to the contents of a numerical control program. Measured analog data indicating the diameter of a workpiece is received continuously to determine if the size of the machined workpiece coincides with the selected reference sizing point. Upon the coincidence of the size of the machined workpiece with the reference sizing point, a sizing signal is provided, and then machining control is changed in response to the sizing signal. An analog signal provided by a measuring device is sampled at a predetermined interval in a predetermined time. The analog signal is tested to see if the analog signal is in a predetermined range, which is decided based upon temperature variation or vibrations of the grinding machine. And the result of test is displayed to facilitate checking the output characteristics of the measuring device. The analog signal is compared with a predetermined reference value, and then the result of comparison is displayed together with a predetermined reference value.

Abstract: Coextrusion apparatus for varying the inner profile of a generally tubular extrudate formed by a first stream of elastomeric material by an axially movable inner die ring which varies the size of an orifice and consequently the flow of a second stream of elastomeric material which is deposited on the inner surface of the tubular extrudate. A compensating ring is axially slidably mounted within the inner die ring and moves generally in an opposite direction to the movement of the die ring to compensate for pressure changes within the second stream of material caused by varying the size of the orifice, to provide an accurately controlled initiation and termination of the material. Pistons are formed integrally on the inner die ring and compensating ring and are located within annular fluid pressure chambers whereby the flow of fluid into the chambers will coordinate the movement of the die ring and compensating ring. A reinforcing guide directs the plurality of fiber reinforcing elements into the tubular extrudate prior to depositing the variable stream of elastomeric material on the inner surface of the extrudate. In another embodiment, a generally constant outer layer of a different elastomeric material may be applied to the outer surface of the tubular extrudate simultaneously with the varying of the inner profile thereof.

Abstract: The invention relates to a circuit of the kind wherein a load (L) is supplied via a triac (TC) with current from an AC voltage supply source (A, B) under the control of a triac control means (IC) in combination with a sensing element (RT). In previous circuits the sensing element is energised by a current from a DC source which is derived by rectification and smoothing of the alternating current of an alternating voltage supply source, which has limitations in integrated circuitry. 
     In the present invention the sensing element (RT) is energised by an alternating current to produce a sensed alternating current. The triac control means (IC) includes an integration means (6) for producing a control signal which is representative of the integral of the difference between a value corresponding with the average peak to peak magnitude of the sensed alternating current and a reference value. The triggering or otherwise of the triac (TC) being determined by a latch (LCH) actuated in response to the magnitude of the control signal relative to one or more threshold levels. 
     The present invention may be used in thermostats or other sensing devices.

Abstract: Underpressure changes in an ink-jet pen (20, 120) reservoir (22, 122) are compensated for by volumetric changes in the reservoir (22, 122) effected by movement of a piston (56, 156) within a sleeve (50, 150) that is connected to the reservoir (22, 122). The piston (56, 156) and sleeve (50, 150) are sized to provide capillarity for holding ink (72, 172) therebetween. The ink (72, 172) between the piston (56, 156) and sleeve (50, 150) acts as a low-friction seal for preventing fluid communication between ambient air and the interior of the reservoir (22, 122). In one embodiment (120), the volumetric efficiency of the pen in enhanced with an auxiliary ink reservoir carried on the piston (156).

Abstract: A refrigerator (11) having a refrigerant circulating circuit (12) for circulating a mixture of a refrigerant and a refrigerating machine oil. The refrigerator (11) includes a compressor (14) with a bypass circuit (31) or a variable displacement compressor (41), a state detecting sensor (19) for sensing a phase of the refrigerant mixture, determining circuit (35) for determining whether the detected phase is in a two phase separation area, and a control unit (36) for controlling the amount of the refrigerant passing through the bypass circuit (31) or the displacement of the variable displacement compressor (41). When the refrigerant mixture enters into the two phase separation area, the amount of discharge or the displacement of the compressor (14, 41) is decreased. The temperature of refrigerant mixture is lowered accordingly and the phase changes from the two phase separation area. The refrigerating machine oil is maintained in a uniformly mixed state with the refrigerant and circulates with the refrigerant to the compressor (14, 41). As a result a lock up or breakage of the compressor (14, 41) is prevented.

Abstract: A clock generator uses coarse and fine phase locking to lock an internal clock signal to an intermittently received data signal. the clock generator uses separate coarse and fine phase locked loops (PLL's). The respective voltage controlled oscillators (VCO's) of the PLL's are made from matched components and the coarse control signal is applied to both VCO's. The fine PLL locks the output signal provided by the second PLL in phase to the received data signal. The oscillatory signal provided by the second PLL is the output clock signal of the system. The fine phase control signal is combined with the coarse frequency control signal to generate the control signal for the second VCO. The fine phase control signal is generated by comparing transitions in a non-return to zero (NRZ) encoded data signal to corresponding transitions in the output clock signal. Phase correction errors made due to missing transitions in the encoded data signal are compensated by one type of phase detector which retains the previous levels of the received data signals. Another type of phase detector gates the clock signal into the loop filter only when it is coincident with detected transitions in the received data signal.

Abstract: Compared with current-compensated current sensors, current sensors with direct measurement have the advantage of a much simpler structure but they exhibit disadvantages in the case of fast current changes or, respectively, high frequencies of the current to be measured. To improve this frequency response, it is proposed to provide, in addition to a magnetic-field sensor (7) which detects the flux of a magnetic core (2) which is influenced by the current to be measured, an electric coil (15) in which a voltage corresponding to the current change of the current to be measured is induced. The output voltages of the magnetic-field sensor and of the coil are added in an amplifier circuit having initially a proportional gain factor and a gain factor which decreases at high frequencies so that a relatively acurate measurement of the primary current is ensured even at high frequencies. <IMAGE>

Also, a climbing exercise apparatus (24,310) is provided having a frame (48,312) on which two pedals (50,316,318) are pivotally mounted to provide a user with a vertically reciprocating exercise movement, and a control panel (51,314) for user input and output.
