Title: Gain switching circuit
Inventor: FURUTA KOICHI
IPC: H03G3/12
Filed: 1989-06-05
Abstract: PURPOSE:To simplify the process by providing a differential amplifier applying current conversion to a difference between an input voltage and a reference voltage given to an operational amplifier and supplying the current obtained by this conversion to the input of the operational amplifier and a control means controlling the operation/inoperation of the differential amplifier. CONSTITUTION:When a control means inactivates a differential amplifier 6, since no current flows to an input of an operational amplifier 2 from the differential amplifier 6, the gain is kept to a 1st value. When the control means activates the differential amplifier 6 on the other hand, since a current based on the difference between an input voltage and a reference voltage flows to the input of the operational amplifier 2, the the gain is kept to a 2nd value which is different from the 1st value. When a high level voltage is given as a switching voltage Vs, since a transistor(TR) Q12 is turned on, a 3rd current mirror circuit 11 is turned off, resulting that a 2nd current mirror circuit 10 is turned off. This means that TRs Q7, Q8 are turned off, resulting in inactivating the differential amplifier 6. Thus, the process is simplified.

Title: Measuring apparatus of water content of dehydrated cake
Inventor: MATSUMOTO TOYOKAZU
IPC: G01N19/10
Filed: 1984-07-10
Abstract: PURPOSE:To enable the immediate and accurate measurement of a water content without touching a dehydrated cake directly by hands by a method wherein a measured value of a stress detected when a pressure-sensitive element of a load cell is pressed into the cake by a prescribed depth is correlated with the water content of the cake. CONSTITUTION:A definite correlationship is found between the press-in resistance of a pressure-sensitive element of a load cell detected when said pressure-sensitive element is pressed by a prescribed depth into a cake and the water content of the cake. When a motor 24 is made to rotate normally and thereby a movable frame 23 is lowered, first a shutter 37 breaks into a cake 20 proceeding on a support table 21 and interrupts the proceeding temporarily. Next, when the pressure-sensitive element 29 of the load cell 28 touches the surface of the cake 20, the motor 24 is stopped by an action of a microswitch 34. When the motor 31 makes one rotation thereafter, the load cell 28 makes one vertical reciprocating operation by the action of a cam 33, the pressure-sensitive element 29 is thereby pressed into the cake 20, and a load at that time is detected by the load cell 28. A measured value thus obtained is converted into the water content of the cake by using the correlationship stated above.

Title: Ecl-ttl level converting circuit
Inventor: MABUCHI HIROSHI
IPC: H03K19/018
Filed: 1984-07-11
Abstract: PURPOSE:To obtain an output waveform without dependancy of a power supply voltage by holding a base current when an output transistor (Tr) is turned on to a constant value even if a power supply voltage is fluctuated. CONSTITUTION:A TrQ12 is biased by constituting a constant current circuit with a resistor R7 and Trs Q7, Q8, Q9, Q11 of diode connection. A base current IB when an output TrQ5 is turned on is a difference between current I1 and I2, where I1 is a current flowing to a resistor R4 at input H level and I2 is a collector current of a TrQ12, and the relation of IB=VBE/R7 is obtained when the resistance value of the resistors R4 and R7 is selected identically and the circuit is immune to the effect of the power supply voltage. Thus, even if the power supply voltage is fluctuated, the depth of the saturation of the output Tr is kept constant and a stable output waveform is obtained.
