Title: Heater controller for oxygen sensor
Inventor: HASEGAWA JUN
IPC: G01N27/409
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To protect an oxygen sensor by suppressing the oxyerheating of the sensor. SOLUTION: An A/F (limiting current-type air-fuel ratio) sensor 30 is attached to an exhaust pipe 12 extended from the main body 11 of an engine 10 and outputs a linear sensor current signal proportional to the oxygen concentration in the exhaust gas of the engine 10 when a voltage commanded from a microcomputer 20 is impressed upon the sensor 30. A CPU 20a in the microcomputer 20 sets the maximum tolerance of the electric power supplied to the heater 33 of the sensor 30 as a power guard and limits the power command value to the heater 33 by means of the power guard. When the sensor 30 is used from a cold state, in addition, the CPU 20a sets the value of the power guard to a higher value than an ordinary value by the period of time reguired for uniformly heating the sensor 30.  Moreover, when F/B control is performed on the element impedance, the CPU 20a judges that the actual power of the heater reaches the power guard and, when the state continues for more than a prescribed period of time, updates a target impedance to the higher side.

Title: Binary picture decoder
Inventor: YAMAUCHI MITSURU
IPC: H04N1/413
Filed: 1986-05-09
Abstract: PURPOSE:To replace a line including errors with binary picture data on a line right before the line including errors with a high correlation and to display the replaced line by decoding binary picture data through the use of two line memories. CONSTITUTION:A decoding control circuit 21 decodes incoming code data, and supplies the decoded binary picture information to the line memory 29 through a switch 22. Simultaneously an address control circuit 23 supplies a write address to the line memory 29 through a switch 25, and the binary picture data on the line concerned is written in the line memory 29. Upon the completion of decoding each line, the decoding control circuit 21 outputs a switching control signal. If an error occurs at the time of decoding the circuit 21 never outputs the switching control signal. Accordingly the switches 22 and 25 28 are not changed over, and picture data on the previous line is again written in the line memory 29. The same data is read out of the line memory 30 and outputted to an output terminal 31.

Abstract: PURPOSE:To reaction as an input generated when magnets enter the shape of projection is alleviated using a force multiplying mechanism to use repulsion effective for rotation by periodically moving a pair of permanent magnets arranged on a fied plate for the constant distance while keeping the shape of projection with movement of a magnet position adjusting plate which moves in conjunction with the fixed plate. CONSTITUTION:Magnets are arranged on a fixed plate and a rotating disk in such a manner that the same poles of magnets are disposed with staggered phases. Magnet arranged on the fixed plate are allowed to make a specified vertical movement and are arranged to form a circle shape and a part of them are projected. In order to form the projected shape, a plate for adjusting vertical position of magnet is used to cause the magnet to work on the loaded device. The number of magnets on the rotating disk is substantially equal to the number of magnets at the oblique side of the proceeding side of the projected shape and these magnets are arranged opposed with each other with deviation of the phases. Moreover, a force multiplying mechanism is used to alleviate reaction to rotation such as a friction, as an input, generated when a magnet enters the shape of projection, or repulsion of magnet on the rotating disk provided opposed to such magnet. Therefore, an continuous running mechanism effective to a constitution provided for rotation can be obtained.
