Title: Voltage-current conversion circuit
Inventor: TANAKA TATSUO
IPC: H03F3/45
Filed: 1992-06-18
Abstract: PURPOSE:To operate a conversion circuit at a lower drive voltage and to disregard the Early effect by biasing a bias voltage of a 1st differential amplifier circuit to a prescribed voltage. CONSTITUTION:Let an emitter resistor of each transistor(TR) Qi (i=1,...6) be rei and a thermal voltage be VT. Then the relation of Vi=i1.(R1+2re1) is established, where i1 is a current flowing in the TRQ1, a resistor R1, the TRs Q2, Q4, Q3. Moreover, the relation of Vi'=i1.2re3=i2.2re5 is established, where Vi' is a voltage between bases of the TRs Q5, Q6. Thus, the mutual conductance Gm between the voltage Vi and TRs Q5, Q6 is expressed in equation I. In the case of R1>>VT/I1, equation II is obtaied and the mutual conductance is inversely proportional to the resistance R1 through the decision of a current conversion ratio I2/I3-I1. However, a drive voltage VCC is expressed in equation II and the VCC is decreased more. Furthermore, when the voltage VCC is fluctuated, the fluctuated component is absorbed by a resistor 2 and a voltage VCE between the TRs Q1, Q2 is not fluctuated and the Early effect is neglected.

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To simply and easily dispose cigarette butts in a type of an ashtray that is used with water added therein for putting off fire for safety by facilitating the separation of the water and the butts. SOLUTION: A highly water-absorptive polymer is formed into a bag shape by covering the polymer with a water-impermeable sheet to provide a water- absorbing sheet body 12. The water-impermeable sheet has a water-inserting opening formed at the part dipped in the water for fire-extinguishing when used, and the water-inserting opening is closed by a sealing material such as an adhesive tape. The water-absorbing sheet body 12 is set in a butt container 11 having a vessel shape so as to be superposed, and used by pouring the water for fire-extinguishing therein. When the butt (a) is disposed, the sealing material is peeled off to open the water-inserting opening, to allow the dirty water to penetrate into the interior of the water-impermeable sheet bag and allow the highly water-absorptive polymer to be soaked to absorb only the water and to separate the butts (a).  The water-absorptive sheet body with the butts is taken out as it is, and disposed as a combustible dirt.

When not matched therewith, a reporting unit, such as a buzzer, arranged at the back of the full panel 4 is operated, it is announced to a user that a thermal power is left non-regulated, and announcing operation is stopped when the thermal power regulator 9 is matched with a rice cooking position. Thereafter, rice cooking is controlled by a signal from the temperature sensor 3a.

Title: Monitoring device for abnormal operation
Inventor: OZAWA RYOICHI
IPC: G06F11/14
Filed: 1992-05-27
Abstract: PURPOSE:To evade the generation of an event continuing repeated outputs and to quickly attain the restart of system operation by forcedly resetting hardware at the time of repeatedly outputting an interruption signal. CONSTITUTION:An interruption signal I1 outputted when a watchdog timer 2 whose count value is cleared at a previously set fixed period is counted up, is stored in a register 5. When the timer 2 is counted up again in the stored state of the signal I1 in the register 5 and outputs the signal I1, a reset processing part 6 forcedly resets a system for clearing the counting of the timer 2. Since the timer 2 is not cleared at its counting, the generation of an event repeatedly outputting the signal I1 can be evaded.

Abstract: PURPOSE:To enable to securely damp the vibration of a type wheel without being affected by the inertia of the type wheel itself, by providing a delaying means for delaying a driving current impressed on a motor for rotating a type wheel on a printing head. CONSTITUTION:In a rotation controller, a positional error converter 20 outputs a signal X when the absolute value of an inputted positional error is not larger than a predetermined value, and outputs a signal Y for the pierod of time for which a signal I is inputted when the inputted positional error exceeds the predetermined value. A signal X1 from an OR gate 23 is inputted into an integrating circuit 21, the first time constant circuit is operated, and the second time constant circuit is operated by the signal Y. On the other hand, a timer 22 generates an output signal for a predetermined period of time on being triggered by the trailing edge of a signal from an AND gate 18. At times other than the time of an initializing operation, the value of the driving circuit supplied to the motor 1 increases gradually. Accordingly, vibrations of the type wheel are securely damped immediately after the start of rotation thereof.

Filed: 1991-07-01
Abstract: PURPOSE:To simply and surely detect a signal by providing two filters, a comparator circuit, a decision circuit, a time protection circuit and a function for utilizing its output signal as a suppression signal and a band stop signal to the in-band one-frequency detection circuit. CONSTITUTION:A linear PCM signal 10 received from an input terminal 1 is inputted to a one-frequency band pass 'digital filter BPF 2, from which only a 1st signal component is extracted and inputted to a frequency band pass digital filter BPF 3, from which.a 2nd signal component with a 1st signal component eliminated therefrom is extracted. The two extracted signal component levels are compared by a comparator circuit 5, which outputs a signal representing whether difference of the both levels is larger or smaller than a set comparison value. When a difference of levels of both the signals is larger than the setting value, a decision circuit 6 outputs a 1st digital code and when a difference of levels of both the signals is smaller than the setting value, the decision circuit 6 outputs a 2nd digital code. Thus, an in-band one-frequency component is not mis-recognized from a frequency component included in a voice signal.

Abstract: PURPOSE:To obtain a robot operation of high accuracy surely at all times by providing a work conditions setting means which sets in order the working conditions of a robot on each a specific point corresponding to the work attribute given by a work attribute operation. CONSTITUTION:The position of a robot is located at the place having passed a point P3 and in case of a point P4 having been looked ahead, the work attribute at this point becomes an arc ON continuous point C and so this time it proceeds from a decision process 531 to a process 536 and the operation of the robot is controlled by the interpolation control by an operation control 3 and the continuous operation control by an operation control 4. Consequently, the bank generation of a welding bead is effectively prevented by the deletion of an interpolation designation at an arc ON section and the guarantee of the continuous operation.

Abstract: PURPOSE: To improve the durability by the seal by a method wherein a pressure transmitting member is provided in a bulkhead provided with a fluid chamber at on side and a gas chamber at the other side to reduce the pressure difference between both of the chambers.  
     CONSTITUTION: A rotor shaft 33 is pentrating though the bulkhead 40 and a gas tight sealing between a distributing chamber 38 and an enclosed chamber 39 is effected by the gas seal 41. A piston member 42 having a seal member 43 is provided slidably in the bulkhead 40. When high-pressure operating gas is flowed into the distributing chamber 38, the pressure in the distributing chamber 38 is increased and the piston member 42 is pushed to the enclosed chamber 39 side thereby increasing the pressure in the enclosed chamber 39. Consequently, the pressures in the distributing chamber 38 and the enclosed chamber 39 are made equal and the pressure will not be impressed to the gas seal 41, therefore, the gas tighthness of distributing chamber 38 and the enclosed chamber 39 may be maintained.
