Patent JP-H05251247-A (JP)
Title: Power supply transformer
Inventor: TAKAHASHI KENJI
IPC: H01F30/00
Filed: 1991-03-07
Abstract: PURPOSE:To enable a power supply transformer to be simplified in circuit configuration, lessened in cost, and enhanced in reliability by a method wherein an alternate current power is concurrently fed to a power supply transformer from two power distribution systems so as to enable it to output a secondary voltage making use of a common iron core which lessens the magnetic circuits of the power distribution systems in degree of coupling between them. CONSTITUTION:An alternate current voltage is applied to opposed inputs A1 and A2 and B1 and B2 from a first and a second power distribution system located on both the sides of a sectional switch. The alternate current voltages are separately transformed by the third leg 10C of an iron core 10 and rectified by diodes 16 and 17 respectively. A direct current voltage obtained as above is outputted through outputs E1 and E2 and used as a direct current power source for a control device of a sectional switch. At this point, even if either the first or the second power distribution system gives out, a direct current voltage can be obtained through the outputs E1 and E2, because a power supply transformer of this design is free from the influence of the failure of one system as a transformer is independent.

Title: Processing system for interruption input
Inventor: NAKAO YOSHIHIRO
IPC: G06F9/46
Filed: 1979-05-31
Abstract: PURPOSE: To determine the priority independently of the sequence of connection from CPU, by providing the unit having the processing function to the interruption request signal between the CPU and the unit.  
     CONSTITUTION: The processing units (ITC)3 and 5 a W5 m  to the interruption request are provided among the CPU1 and the interruption request producing sources (units) 7 aa W7 am , 7 6a W7 6m ,...7 ma W7 mm . When an interruption request is produced in the units, the ITC3 outputs the interruption request transmitting instruction to the ITCs 5 a W5 m . When the ITCs 5 a W5 m  receive the interruption request transmitting instruction, this is transmitted to the unit. The ITCs 5 a W5 m  fetch the interruption request from the units at a bundle. The ITC3 repetitively outputs the interruption request transmitting instruction until the address input instruction is incoming and can determine the priority independently of the sequence of the connection from the CPU of the units.

Title: Continuous metering method for fluid contained in plurality of tanks
Inventor: YAMAZAKI KAZUHIRO
IPC: G01F13/00
Filed: 1993-03-26
Abstract: PURPOSE:To prevent the occurrence of errors in the measurement of a flow rate due to air bubbles mixed in by the idle running of a pump by employing a centrifugal pump which has no self-supporting property, and does not feed fluid at all when air is mixed in by the idle run of the pump. CONSTITUTION:A pump P which has no self-supporting property, is used as a fluid feed pump. In this case, supporse the quantity of fluid contained in a reserve tank T1 does not meet a specified quantity, if the reserve tank T1 is emptied, air comes in pipelines which causes the pump P to run idle, and no fluid is fed, so that a meter D thereby stops measuring. If the meter D stops at a stage before the specified quantity, the pump P is suspended, the valve B1 of the reserve tank T1 is closed, the valve B2 of the next reserve tank T2 is opened, and an air vent valve B6 of the pump P is opened, so that air is thereby vented. After air has been vented, the pump P is restarted, and pumping is kept on until fluid comes up to a specified quantity. Thus, the specified quantity of fluid can thereby be metered into a specified container by operations as mentioned above.

Title: Sheet feeder for transfer type recorder
IPC: B41J17/38
Filed: 1992-03-26
Abstract: PURPOSE:To reduce the releasing force acting on the part of recording sheet where ink is transferred when the part is separated (cut) from an ink doner film. CONSTITUTION:Since a release bar 4 is disposed obliquely at a predetermined angle to a vertical attitude to a feeding direction on a feeding surface when an ink doner film F after transferring in a close contact state and a recording sheet P reaches the bar 4, part (printed dots) of the sheet P where ink is transferred is released from an oblique direction. Thus, a shearing force acting on the front edge of the ink-transferred part of the sheet P first reaches a cutting shearing force (shearing force of a magnitude to start cutting of ink) for cutting part of the edge. In this case, the force acting on the other part of the edge does not yet reach the cutting shearing force. Accordingly, since the cutting shearing force is not simultaneously operated at the entire area of the edge of the ink-transferred part, the force acting on the part is reduced.

Abstract: PURPOSE:To form a timer of a comparative long time limit by a simple circuit, by converting the charge accumulated in a capacitor to a pulse current synchronizing with supply voltage, and applying it to the gate of an Ac thyristor. CONSTITUTION:This timer is constituted so that to the base of a transistor 13, a pulse current of suitable phase is applied at its every semi-period against AC supply voltage. When a switch 9 is closed in this state, a capacitor 8 is charged at every 1 period in which forward voltage is applied to diodes 10, 7, is discharged at every semi-period through the gate of an AC thyristor 4 by the transistor 13, and almost constant potential is held at a place where the quantity of discharge and the quantity of charge are balanced. When the switch 9 is opened in this state, the capacitor 8 is not charged, and the AC thyristor 4 is turned on continuously for a constant interval of time, discharging the accumulated charge in order at every semi-period. According to such a constitution, it is possible to obtain a timer of a comparatively long time limit by a simple circuit.
