Abstract:
A magnetic array sensor circuit to process an output from a magnetic sensor array including a plurality of magnetic sensor elements arranged in an array. The circuit includes a regulating circuit to reduce an offset variation of the output from the magnetic sensor elements arranged in the array. The regulating circuit includes a control circuit to operate the magnetic sensor element in a linear region. The control circuit includes a reference sensor element in the form of the magnetic sensor element short-circuited between two output terminals, a storage element to store a reference offset value read out from the reference sensor element, and a subtraction circuit to subtract the stored reference offset value from an output of the other magnetic sensor elements.
Abstract:
A reference current generating circuit includes an operational amplifier having one input terminal to receive a reference voltage and a field effect transistor having a gate to receive an output voltage of the operational amplifier. k resistors (k is an integer not less than 2) are connected in series to a drain of the field effect transistor, and a voltage at one of connection points of the resistors is feed backed to the other input terminal of the operational amplifier. A switch selects one of the connection points of the resistors and applies the voltage of the selected connection point as a reference voltage to a gate of a reference transistor to generate a reference current.

Abstract:
A method for producing a crystallized polyester comprises the crystallization step of applying a shear and/or a pressure to a polyester selected from an aliphatic polyester and a polyalkylene terephthalate at a temperature of (Tm−70° C.) to (Tm+20° C.), where Tm is a melting point of the polyester, thereby converting the polyester into a state having a crystallinity of 10% or more and fluidity.
