Title: Air/fuel ratio detecting device
Inventor: MIZOGUCHI ASAMICHI
IPC: G01N27/41
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide an air-fuel ratio detecting device which can detect air-fuel ratios in any air-fuel ratio domain. SOLUTION: The A/F detecting section 11 of an A/F sensor 10 has a solid electrolyte layer 14 and a diffused resistor layer 13 and outputs an electric current having the value corresponding to the oxygen concentration of an exhaust gas when a voltage is applied across the exhaust gas-side and air-side electrodes 15a and 15b of the electrolyte layer 14. An oxygen supplying and exhausting section 12 has a solid electrolyte layer 16 and a pair of electrodes 15c and 15d respectively formed on both surfaces of the layer 16 and supplies oxygen to the vicinity (air chamber 18) of the air-side electrode 15b of the A/F detecting section 11 or exhausts the oxygen near the electrode 15b.  A control section 30 fetches the limiting current value Ip detected by means of a current detecting section 40 and controls the oxygen supplying or exhausting amount of the oxygen supplying and exhausting section 12. To be concrete, the control section 30 controls the oxygen supplying and exhausting amount of the section 12 by variably setting the target control value of the current flowing to the electrolyte layer 16 so that the moving amounts of oxygen in the electrolyte layers 14 and 16 may become equal to each other.

Title: Probe for measurement of electrical characteristic of semiconductor wafer
Inventor: YANAGIHARA HIROSHI
IPC: G01R1/073
Filed: 1986-02-27
Abstract: PURPOSE:To stabilize the setting of a characteristic impedance and to contrive the reduction of cross-talk by arranging transmission lines in parallel on a dielectric substrate and providing ground lines among the transmission lines. CONSTITUTION:Three transmission lines 11 are arranged in parallel and in longitudinal direction on a dielectric substrate 10. A front end part of each line 11 is bent upward and rises. Between this rising part and the substrate 10, a space 13 is formed and the rising part is a contact part. Ground lines 14 are arranged in parallel on the substrate 10 among the lines 11 and on both sides of them. In this probe 16, as the lines 11 are thus arranged in parallel on the substrate 10 and the lines are of a strip line structure, a characteristic impedance of the lines 11 does not change and is constant in any part. Also, as the intervals among the lines 11 are sealed with the lines 14, cross-talk is reduced and a noise is exceedingly reduced.

Then, the head a2 reproduces the track Ta2 at the same time when the head a1 reproduces the track Ta1. Then, the two tracks are reproduced at the same time simultaneously and two reproducing signals PB,D.PB having the time interval of one field are obtained at the same time. A Y signal separated from the signal PB is demodulated at a demodulation circuit 7 and a D.Y signal separated from the signal D.PB is demodulated at a demodulation circuit 8 and they are applied to an adder 9. When the correlation of field exists between the FM-Y signal and the FM-D.Y signal, the Y signal with reduced noise is obtained from the adder 9.

IPC: G06T11/20
Filed: 1990-02-23
Abstract: PURPOSE:To improve the transfer efficiency of a graphic command by simplifying and displaying the character graphics which are meaningless even when displayed in plotting of character graphics. CONSTITUTION:A coordinate converting means 1 converts the character graphics assigned by a user from the world coordinates assigned by the user to the device coordinates of a graphic display device. A judging means 2 calculates the size of the character graphics in the device coordinate on the actual graphic display device in accordance with the results of the conversion of the coordinate converting means 1 and makes decision as to whether the graphics converted to the device coordinates have the resolution to the extent of having meaning as the character. The means converts the graphic character to the more simplified graphics if the graphics are meaningless as the character. A graphic command forming means 3 forms the graphic command in accordance with the result of the judgment of the judging means 2. A graphic display means 4 displays the graphics by the graphic command formed by the graphic command forming means 3. The transfer efficiency of the command is thus improved.

Title: Optical repeater
Inventor: DEGUCHI HIROYUKI
IPC: H04B10/29
Filed: 1990-02-23
Abstract: PURPOSE:To reduce number of components and to simplify the constitution by employing two sets of optical amplifiers comprising a 1st optical amplifier of a main transmission system and a 2nd optical amplifier for loopback and controlling the gain so as to use them in common for optical amplifiers and optical shutters. CONSTITUTION:In normal operation, 2nd optical amplifiers 14, 14' receiving a branched optical signal are turned off and an input optical signal from a pre-stage repeater is amplified directly by 1st optical amplifiers 13, 13' and sent to a post-stage repeater. Then at loopback, when a monitor section 12 detects a loopback command, the 1st optical amplifiers 13, 13' are turned off and the 2nd optical amplifiers 14, 14' are turned on. Thus, the optical output to the post-stage repeater is stopped and the branched optical signal from branching devices 11, 11' is amplified by the 2nd optical amplifiers 14, 14' and sent to an opposite transmission line. Thus, without use of an optical switch, the loopback circuit for the optical repeater relaying the optical signal by direct optical amplification is formed. Thus, number of components is reduced and the cost is reduced and the size is made small.
