Title: Voltage comparation circuit
Inventor: NAGAYAMA YOSHIHARU
IPC: H03K5/08
Filed: 1984-04-06
Abstract: PURPOSE:To shorten a time required for the clear of a capacitor by connecting a level limiter circuit to the drain output of a differential MOSFET to reduce an output voltage difference. CONSTITUTION:When the level difference between a reference voltage Vref and an input signal (in), a drain voltage is sharply changed in accordance with gain due to the amplifying operation of differential MOSFETs Q1, Q2. If the drain voltage is changed so as to exceed the threshold voltage of MOSFETs Q9, Q10 by regarding a level limiter voltages as a reference, the MOSFETs Q9, Q10 is turned to the ON state, so that a load resistance value is suddenly reduced. Consequently, amplification gain is limited, so that the drain voltage of the differential MOSFET Q1 or Q2 is practically limited to a fixed level.

Filed: 1995-03-27
Abstract: PURPOSE: To prevent occurrence of error in learning correction while accurately controlling an air-fuel ratio in an area where learning correction is not completed during air-fuel ratio controlling. CONSTITUTION: An air-fuel ratio correction rate FAF is calculated based on outputs of O2 sensors 28, 29 arranged respectively on upstream side and downstream side of a catalytic converter 17 of an exhaust passage 16a of an engine 1.

Title: Slump test measuring device
Inventor: YASOJIMA HARUNORI
IPC: G01B11/00
Filed: 1994-04-06
Abstract: PURPOSE:To enable the real-time measurement of the test result of the slump value or the like by disposing height detecting means for flowable concrete vertically and horizontal position detecting means for flowable concrete horizontally. CONSTITUTION:When concrete 18 in truncated cone shape flows out spreading around by its fluidity and at the same time the top part is also lowered, the intercepted state of infrared rays is shifted to the non-intercepted state successively between projectors 2 and light receivers 4 lined up vertically. The slump value is computed from this change by a height computing program in an arithmetic processing unit. With the spread of concrete 18, the infrared rays are intercepted one after another between the projectors 2 and light receivers 4 of X-Y direction position detecting means 8, 9. In the arithmetic processing unit, the time when each infrared ray is intercepted is clocked and displayed. The result of a slump test can be thus known real time immediately after the test.

Filed: 1981-05-07
Abstract: PURPOSE:To perform both the constant current driving and the constant speed driving of a reel motor in good condition, by carrying out the switching according to the operation mode of a tape deck. CONSTITUTION:A bridge circuit 10 is formed by using a reel motor 1 and a driving current detecting resistance R1 for the sides respectively and inserting a reference voltage source 2 to the side which is opposed to the resistance R1. A differential amplifier 3 uses the difference of potential between the detecting terminals B and C of the circuit 10 for the differential input; and a differential amplifier 6 uses the both-end voltage of the resistance R1 for the differential input. The constant speed travelling and the high speed travelling of a tape are switched in accordance with the operation of switches 4 and 8. Then the output of the amplifier 3 or 6 is supplied to the feed terminal A of the circuit 10 via a current amplifier 5. Furthermore each constant of the circuit 10 is set so that the load characteristics of the motor 1 bring about the coincidence between the start and end points of the tape winding with a characteristic curve which keeps the constant speed for the travelling of the tape. Thus the constant speed control is performed for the motor in the high speed driving mode.
