Title: Apparatus for measuring oxygen concentration
Inventor: KITAHARA TAKESHI
IPC: G01N27/406
Filed: 1984-04-04
Abstract: PURPOSE:To enhance the durability and detection accuracy of a sensor, by cyclically changing over objective voltage to positive and negative predetermined values and calculating the same on the basis of at least one of a pump current value when the objective voltage is a positive predetermined value and that when a negative predetermined value. CONSTITUTION:The sensor part 14 of an oxygen sensor 1 has a measuring electrode and a reference electrode arranged thereto and outputs voltage Vs corresponding to the oxygen partial pressure ratio between both electrodes. A pump electrode is arranged to a pump part 15 and the oxygen partial pressure ratio between both electrodes of the sensor part is determined corresponding to the value of an influent current Ip. A current supply means 31 supplies the current Ip to the pump part 15 so as to bring voltage Vs to predetermined objective voltage Va and an objective voltage change- over means 32 cyclically changes over voltage Va to positive and negative predetermined values. An oxygen concn. detection means 37 detects the current Ip and outputs a voltage signal  Vi corresponding to oxygen concn. from the value of the current Ip when voltage Va is a positive predetermined value and that when a negative predetermined value. By this method, the durability and detection accuracy of the sensor can be enhanced.

Title: Digital phase comparison circuit
Inventor: SHIMURA KENJI
IPC: H03L7/085
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a precise comparison output signal which does not contain a hazard by providing an RS flip flop for inputting a first signal to a set terminal, a second signal to a reset terminal, for inputting the output of an AND gate to a control terminal and for supplying an output signal to a three state buffer. SOLUTION: When the RS flip flop 6 inputs an REF(reference) SET signal to the set (S) terminal, inputs a VAR (comparison) SET signal to the reset (R) terminal and inputs the output signal of the AND gate 6a to the control (CP) terminal, the output signal of the RS flip flop (with gate) 6 becomes the RSQ signal (corresponding output) of a long '1' period. The three state buffer 5 of a post stage becomes gate enable by the EN(enable) signal having the '1' period contained in the '1' period of the RSQ signal and the corresponding period of the RSQ signal is outputted. Thus, '1' period of comparison output (PD) does not contain the hazard and the precise comparison output (PD) signal is obtained.

Title: Simultaneous bidirectional fm transmitter-receiver
Inventor: YOSHISATO AKIYUKI
IPC: H03D3/00
Filed: 1988-03-22
Abstract: PURPOSE:To prevent beat generating, to miniaturize a circuit and to save power by forming a first intermediate frequency signal corresponding to the difference of a transmitting/receiving frequency in a first mixer, forming a base band signal to have the phase difference of 90 degrees in a second mixer and demodulating the base band signals by an FM direct converting system. CONSTITUTION:The output of a PLL synthesizer for transmitting PLL2 is connected to the local input terminal of a first mixer 4. Besides, a PLL synthesizer PLL3 of a fixed channel is used as a second local oscillator. Consequently, a first IF frequency becomes 45MHz which is the difference of a transmitting frequency and a receiving frequency. In second misers 6a and 6b, the output signal of the PLL synthesizer for second local oscillation PLL3 and a 45MHz differential signal are frequency-mixed and converted into a base band signal. Consequently, the FM modulating component of a first local oscillating signal is cancelled by the FM modulating component of a second oscillating signal. Thus, spurious emission and the generation of a beat as an unnecessary interfering wave can be prevented, moreover, a circuit scale and the consumption power of a circuit can bed reduced.

Filed: 1987-03-24
Abstract: PURPOSE:To enhance the recovery efficiency of product, by providing a recirculation beam path returning the reflected beam of incident laser beam to the reflecting surface of a half mirror to recirculate a part thereof and a collimating lens contracting the beam diameter of recirculated laser beam. CONSTITUTION:A first collimating lens 23 is interposed on the beam path connecting both reflecting surfaces of the first half mirror 21a and the third total reflection mirror 21d and, when a laser beam 9 is transmitted through the collimating lens 23, the beam diameter 9a thereof is contracted to that of the incident beam 9in from a laser beam source. Therefore, since the beam diameter 9a of the laser beam 9 recirculating through the first beam recirculation path 21 is always held at that of the incident laser beam 9in and the magnification of the beam diameter is prevented, the lowering of the excitation and ionization capacity per unit cross-sectional area of the laser beam 9 can be prevented.

Title: Drop-out detecting device for optical disk reproducing device

Filed: 1986-03-26
Abstract: PURPOSE:To detect a drop-out in the condition of an original signal and to simplify a circuit constitution without executing the signal processing such as an FM demodulation by comparing two sum signal waveforms and detecting the drop-out. CONSTITUTION:When a drop-out occurs and the period of a part of a sum signal A+C is short, for D flip-flop circuits 90 and 92, the fall zero cross of the A+C of the sum signal is inputted only to a clear input CL two times continuously while the rise zero cross of the B+D of the sum signal is inputted, and therefore, the D flip-flop circuit 92 is not set. Since for a D flip-flop circuit 94, the rise zero cross of the sum signal A+C is inputted to a clock input CK two times continuously while the fall zero cross of the sum signal B+D is inputted to the clear input CL, a D flip-flop circuit 96 is set by the second input and a drop-out detecting signal is outputted from an OR circuit 98.

Abstract: PURPOSE:To produce a high-purity brominated novolak resin by introducing bromine atoms into only the aromatic ring of a novolak resin, by brominating the novolak resin dissolved in a solvent in dark in the presence of a radical- reaction inhibitor. CONSTITUTION:A novolak resin of formula I (wherein R is H or methyl, and n is 0-8), e.g., phenol novolak or cresol novolak, is dissolved in a solvent inert to the brominating agent (e.g., methanol or carbon tetrachloride) and about 0.05-1pts.wt., per 100pts.wt. resin, radical-reaction inhibitor (e.g., hydroquinone or methacryloyl chloride) is added to the solution. While the reaction mixture is being violently agitated in dark, the reaction is effected by adding bromine dropwise (at about -20-70 deg.C for about 0.5-10hr) to produce a brominated novolak resin of formula II (wherein x and y are each 0-2).
