Inventor: TAKEUCHI HIROKIMI
IPC: B23K9/00
Filed: 1982-05-13
Abstract: PURPOSE:To weld a coated steel plate without defect and with little spatter, by using specified argon gas as shielding gas and using a power source of pulse lapping type as a welding power source. In arc welding of a specified coated steel. CONSTITUTION:When arc welding a steel plate coated with a primer composed mainly of 10-50% zinc dust, denatured alkyl silicate and conductive pigment, argon gas containing <=30% CO2 and/or O2 is used as shielding gas.

Title: Optical communication equipment
Inventor: KOIZUMI YOSHIAKI
IPC: H04B17/00
Filed: 1989-03-30
Abstract: PURPOSE:To detect the power failure of a communication opposite station in a moment and to immediately execute a recovery processing by informing the power failure to the communication opposite station based on whether or not a power failure detecting signal is reflected. CONSTITUTION:An optical signal for power failure detection passing a light cable 32 is inputted to a power failure information unit 15. The detection of the power failure of its own station 10a by the communication opposite station 20a can be judged based on whether or not the optical signal for power failure detection is reflected as it is. In other words, the power failure information unit 15 reflects the signal of the light cable 32 by a liquid crystal mirror 15a which controls the signal of the light cable 32 when a power source is applied, and evades the reflection of the signal of the light cable 32 when the power failure occurs. In such a way, it is possible to detect the power failure by the communication opposite station 20a, and to quickly perform the recovery processing.

Title: Key input circuit
Inventor: MARUYAMA YUICHI
IPC: G06F3/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a key input circuit which is free from a through current at push of keys and suited to the use of the low current consumption by setting repetitively and alternately only the terminal that has the key input when a key is pushed at high and low levels respectively synchronously with a clock. CONSTITUTION:When a switch is pushed, a short circuit is produced between both I/O terminals 3 and 6. Thus a clock is started and at the same time a MOSFET 2 is turned off. When the clock is set at a low level, the terminal 6 is set at a high level since both terminals 3 and 6 are short-circuited to each other. Thus the push of a key is detected. Then the terminal 3 is stabilized at a high level when the key is released together with the terminal 6 stabilized at a low level respectively. A key matrix circuit is usually applied with capacity of about 100-300PF for prevention of the chattering and actually never have a high impedance for half cycle of the clock. Under such conditions, no through current flows at all.

IPC: B25J13/00
Filed: 1986-04-08
Abstract: PURPOSE:To enable a servo controller to easily correspond to the increase/ decrease of the number of actuators by respectively including actuators in plural position controllers to control a servo loop. CONSTITUTION:The position controllers 7 constitute the servo loop through driving motors for the actuators 8 and optical encoders to be angular sensors and control joints connected to the motors so as to make the motors follow a position command value outputted from an interface controller 6. Memories in the controllers 7 are common memories with the controller 6 to read or change all the internal states of the controller 7. Thereby, the servo controller can be facilitated to correspond to the increase/decrease of the number of actuators by connecting the controller 7 to be charged to a bus.

Title: Differential amplifier having signal-following zero-input current control function
Inventor: PIETERU HERITSUTO BURANKEN
IPC: H03F3/45
Filed: 1992-04-02
Abstract: PURPOSE: To stabilize the operation by putting together 1st and 2nd led currents of 1st and 2nd current generators which generate the 1st and 2nd currents and generating and outputting a measurement current, and allowing a higher input signal frequency of the differential amplifier. CONSTITUTION: The base-emitter voltage of a transistor(Tr) and the current flowing to the Tr has logarithmic relation. Consequently, the product j1 *jA of a current J1 flowing to a TrT1 and a derived current JA is proportional to the product JQ≪Q of currents JQ flowing to Trs T5 A and T4 A. Similarly, a current J2 *JB is proportional to a current JQ*JQ. Therefore, derived currents JA and JB are in inverse proportion to J1 and J2 . At a control terminal 11, the derived currents JA and JB are added to each other to generate a measurement current JA+JB, which is compared with a reference current 2JQ; and a difference signal Js flows from the terminal 11 to a control input 5 of a controllable zero-current source 4.  When J1 =J2 , JA and JB are both equal to JQ, so a current Js does not flow to the base of a TrT3 and a current Jo is minimum, so that the currents J1 and J2 become JQ+Jo /2.

Title: Electrodialysis apparatus
Inventor: URABE SUNAO
IPC: B01D61/50
Filed: 1980-06-17
Abstract: PURPOSE: To hardly generate neutral disturbance phenomenon in an electrodialysis apparatus equipped with an elongated flow passage by making a cross area of the flow passage in a concentrating chamber or a diluting chamber smaller at an outlet side.  
     CONSTITUTION: A width of a flow passage in at least one of a concentrating chamber and a diluting chamber of an electrodialysis apparatus, pref., in the diluting chamber is made narrower toward an outlet 4 in the order of a>b>c>d>d. Generally, a limit current density is propotional to a concn. of a liquid in the diluting chamber and lowered toward an outlet direction but, when a flow speed of a desalted liquid on a membrane surface becomes larger, the limit current density is also increased. Therefore, in the above described electrodialysis apparatus, because a flow speed of the liquid is increased toward the outlet 4 where a concn. of the chamber liquid becomes lower, the current density in the vicinity of the outlet is prevented from approaching to a limit and total current density can be increased.

On the other hand, the output from a scanning signal generator 31 is applied to a lateral axis electrode, and since the synchronization is secured, the still image of the mass spectrum is obtained on the CRT 37. Therefore, the scanning width of the electric field can be found and the operational property of the ion type selection can be improved broadly.

Title: Current limiter
Inventor: HARA CHIKUSHI
IPC: H02H9/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To see that a current limiter does not incur the pressure rise within an adiabatic container at the time of current limitation, and that it can fulfill the duty of a reclosing path by connecting the cooling stage of a cryogenic refrigerator with a superconductor, and cooling the superconductor below the critical temperature. SOLUTION: When a short circuit accident occurs, a line current I and a line voltage change, and a controller 41 detects the occurrence of an accident. Then, the controller 41 operates a breaker to break the circuit 20 ms later from the point of time of detection. Subsequently, it cuts off a disconnector 30a which are connected in series to each current limiter unit 29a inserted into each line from each line. Next, the controller 41 controls a disconnector 30b, connected in series to a current limiter unit 29b to 'close', and subsequently it turns on a breaker 24 again. Here, the temperature of the superconducting coil 31 of each current limit unit 29a is rising but is cooled again by a cryogenic refrigerator 34, and soon it falls below the critical temperature, and goes into standby condition.
