Title: Flip-flop circuit
Inventor: KINUGASA MASANORI C O INT PROP
IPC: H03K3/3565
Filed: 1990-09-05
Abstract: In a master-slave type flip-flop circuit comprising a master output holding circuit (13) of the master stage circuit, the threshold value of the input circuit of the slave stage circuit (17) has a hysteresis characteristic in which the high level threshold value (V IH ) is set to a higher value than the threshold value of the master output holding circuit and the low level threshold value (V IL ) is set to a lower value than the threshold value of the master output holding circuit. Due to the feature, a phenomenon is prevented in which the output is once inverted and then again inverted in the metastable state.

Abstract: The invention describes an adjustment procedure for a nondispersive infrared gas analyser for determining the concentration of a gas component having a high basic concentration and low variation in concentration. 
<??>A reference gas having the basic concentration is drawn off from the test gas. This gas is passed through the reference side of the beam path of a gas analyser (flowing reference gas). The gas analyser now measures the test component as the difference between the test gas and the basic concentration. The residual dependence of the sensitivity of the measured quantity on the basic concentration is eliminated by the following procedural steps: 
 
  - in the first step, the test gas having the current basic concentration is passed into the test and the reference cells of the gas analyser and the zero point of the gas analyser is aligned; 
  - in the second step, a calibration cell is inserted into the beam path of the two cells, the calibration cell being filled with the test component at a specified concentration which corresponds to the desired measurement range of, for example, 50 ppm and the sensitivity is adjusted in such a way that this measurement range corresponds to the measurement interval.

Abstract: An air-fuel ratio detecting device is disposed in an exhaust gas passage of an engine, and detects the oxygen concentration in exhaust gases to produce a signal indicative of the air-fuel ratio of an air-fuel mixture supplied to the engine. The air-fuel ratio detecting device serves as a linear A/F sensor for detecting whether the air-fuel mixture is on a leaner or richer side of a stoichiometric ratio and also detecting the value of the air-fuel ratio. An electric signal representative of the oxygen concentration in a detection chamber supplied with exhaust gases is applied by a sensor cell to a controller which then controls a pump cell to cause the oxygen concentration in the detection chamber to indicate a nearly stoichiometric ratio. The air-fuel ratio detecting device can continuously detect the air-fuel ratio with an electric control signal from the controller. The stoichiometric ratio is detected when the potential difference between the electrode of the pump cell jumps or discontinuously varies. Since the oxygen concentration difference directly serves as detected stoichiometric ratio information, the stoichiometric ratio can be detected with an increased response. The stoichiometric ratio may be detected, using a variable threshold value, based on the potential difference across the pump cell, and the threshold value is selected depending on a control parameter for fine adjustment of a target air-fuel ratio.

Abstract: A facsimile apparatus including a cordless telephone set having a remote unit includes photocouplers PC1 and PC2 for detecting whether the handset of a remote unit 3 is at an off-hook condition or not. When the handset is at an off-hook condition, a signal indicating this state is transmitted to a control CPU 9 via photocouplers PC1 and PC2 and phototransistors Q1 and Q2. The control CPU 9 applies a signal from a telephone line monitoring transformer T2 that monitors the condition of a telephone line 6 via a FAX modem 8. When detection is made that the handset of the remote unit is at an off-hook condition even though telephone line 6 is under a condition where the communication has terminated, the handset of the remote unit is set to an on-hook condition through a base unit 5.

Abstract: An input analog image signal is sampled by first and second A/D converters (15, 16), using first and second sampling clocks (SCK1,SCK2) of the same period, to obtain pieces of digital gradation data. In the case of a double definition display mode, the first and second sampling clocks (SCK1,SCK2) are made 180° out of phase with each other and the output of the first A/D converter (15) is delayed for one-half period, by which its timing is brought into agreement with that of the output of the second A/D converter (16), thus obtaining a pair of digital gradation data. In the case of a standard definition display mode, the first and second sampling clocks (SCK1,SCK2) of the same phase are used to obtain the outputs of the first and second A/D converters (15, 16) as a pair of digital gradation data. The pair of digital gradation data Da and Db is converted by a signal processing part (20) into a pair of analog gradation data Aa and Ab, which is subjected to a serial-to-parallel conversion by a source driver (13) to be supplied in parallel to data lines. In the double definition display mode the gate driver sequentially drives odd-numbered row lines in odd-numbered frames and even-numbered row lines in even-numbered frames. In the standard definition display mode every two adjacent row lines are simultaneously driven in a sequential order.

Abstract: A coin processing apparatus arranged to automatically execute a cancellation process for canceling acceptance of an inserted coin by detecting, on the basis of output levels of receiving coils (8a,8b) in a plurality of sets of coin selecting coils (7a,7b,8a,8b) disposed on a coin path (6), a fact that the inserted coin has been guided into a return path through the operation of a return lever, and also to judge the occurrence of coin jamming and coin counter-flow on the basis of the output levels of the receiving coils (8a,8b). The output level of the receiving coil (8a,8b) in each of the plurality of sets of coin selecting coils (7a,7b,8a,8b) is monitored so as to carry out the automatic cancellation process in case the output levels of the respective receiving coils (8a,8b) concurrently exceed a predetermined threshold level and persist longer than a predetermined period of time. In case the output level of the receiving coil (8a,8b) in at least one of the plurality of sets of coin selecting coils (7a,7b,8a,8b) exceeds the predetermined threshold level and persists longer than a second predetermined period of time, it is judged that the coin jamming has occurred. Further, in case the output level of the receiving coil (8a,8b) of the most downstream one of the plurality of sets of coin selecting coils (7a,7b,8a,8b) exceeds the predetermined threshold level and the detection output occurs again after the lapse of a third predetermined period of time from the time point when the detection output has once ceased, then the coin judged as a true coin is treated as a false coin.

Abstract: A data processing system, method and program are disclosed, for managing a public key cryptographic system. The method includes the steps of generating a first public key and a first private key as a first pair in the data processing system, for use with a first public key algorithm and further generating a second public key and a second private key as a second pair in the data processing system, for use with a second public key algorithm. The method then continues by assigning a private control vector for the first private key and the second private key in the data processing system, for defining permitted uses for the first and second private keys. Then the method continues by forming a private key record which includes the first private key and the second private key in the data processing system, and encrypting the private key record under a first master key expression which is a function of the private control vector. The method then forms a private key token which includes the private control vector and the private key record, and stores the private key token in the data processing system. 
     At a later time, the method receives a first key use request in the data processing system, requiring the first public key algorithm. In response to this, the method continues by accessing the private key token in the data processing system and checking the private control vector to determine if the private key record contains a key having permitted uses which will satisfy the first request. The method then decrypts the private key record under the first master key expression in the data processing system and extracts the first private key from the private key record. The method selects the first public key algorithm in the data processing system for the first key use request and executes the first public key algorithm in the data processing system using the first private key to perform a cryptographic operation to satisfy the first key use request.
