Abstract: PURPOSE:To secure high reliability and to prevent a lead shortcircuit due to gold plating, by constituting a lead pattern by laminating a medium purity aluminum membrane to a high purity aluminum membrane in an exposed state and applying gold plating and solder coating to a part thereof to form a flexible cable connecting terminal part. CONSTITUTION:A lead pattern 4 is set to a double laminated structure wherein a medium purity aluminum (3N-Al) membrane 6 is laminated to a high purity aluminum (5N-Al) membrane 5 and, further, a gold wire 7 subjected to wire bonding pierces through the medium purity aluminum membrane 6 to reach the high purity aluminum membrane to form a gold/aluminum covalent bond alloy and is substantially bonded to the high purity aluminum membrane being a lower layer through said alloy. Therefore, even when no gold plating is applied to the lead pattern 4, the highly reliable wire bonding to said lead pattern becomes possible and, since gold plating becomes unnecessary because of wire bonding, a lead shortcircuit apprehended when gold plating is applied to a fine lead pattern is eliminated perfectly.

Filed: 1978-10-16
Abstract: PURPOSE: To enhance the high frequency properties of the power amplifier incorporating the complementary SEPP circuit by adding two units of transistors to give the quick discharge to the storage carrier.  
     CONSTITUTION: The emitters and collectors of transistors TRQ 9  and TRQ 10  are connected between the bases of TRQ 7  and Q 8  which are the output steps of the complementary SEPP circuit. In this way, the discharge time constant is decreased for the storage carriers of TRQ 7  and Q 8 , and thus the accumulated carrier is discharged quickly through TRQ 9  and Q 10 . Thus the effect of the accumulated carrier can be eliminated. As a result, the output distortion can be eliminated at the high frequency band to enhance the high frequency properties. In addition, the excessive power consumption is eliminated for TRQ 7  and Q 8  to avoid the deterioration of the properties and the breakdown.

Abstract: PURPOSE:To make analogue-digital conversion high-precision and high-speed, by comparing a sampled input analogue voltage and a comparison reference voltage, which passes through a 1/2 attenuator, with each other by applying the comparison reference voltage to the 1/2 attenuator again after adding the comparison voltage to the comparison reference voltage or as it is on the basis of the comparison result to obtain the comparison reference voltage. CONSTITUTION:An input analogue voltage Vin is held in a voltage holding circuit 21(C), and a reference voltage Vref is held in a voltage holding circuit 21(A). A voltage holding circuit 21(B) holds the zero level, and an output Vc of an analogue adder 22 becomes Vref. The output of the adder 22 passes through a 1/2 attenuator 24 to become a comparison reference voltage VE, and this voltage VE is applied to a comparator A11. If VE>VF [the output of the cirucuit 21(C)] is true, a control signal phi2 is set to 1, and control signals phi1, phi3, and phi4 are set to 0. If VE<=VF is true, the signal phi2 is set to 1, and signals phi1, phi3, and phi4 are set to 0. Hereafter, signals are set similarly, thereby obtaining a desired digital value from Vout.

Abstract: PURPOSE:To attain simple constitution by setting a duty ratio or a frequency of a pulse signal fed to a CR time constant circuit and using a digital signal inputted from the 2nd digital input port so as to detect the physical change in an object to be detected. CONSTITUTION:The duty ratio t1 of a pulse signal outputted at first from an output port D0 is set to t1=t2/2 by a microcomputer 11, the 1st input port D1 is read, and when t3>t4, the pulse signal where the duty ratio is changed to decrease the t1 is set and when t3>t4, the pulse signal where the duty ratio is changed to increase the t1 is set. Then the relation of t3=t4 is attained finally. Then the value of the 2nd digital input port D2 is read for temperature detection in this state for a control such as heater control. Since a CR time constant circuit 15 and a transistor 16 only are used in place of a conventional voltage comparator circuit, the constitution is simplified.
