摘要： PURPOSE:To easily lead in local and remote tests, by inserting a nonlinear element between a test connecting circuit and a telephone set side line, in a subscriber's circuit of a time division switchboard. CONSTITUTION:A telephone set TEL is connected to a subscriber's circuit SUB through a line L, a nonlinear element SV such as a two-way diode, etc. is inserted into the line, and the element SV transmits a small amplitude AC which has been superposed on DC, but it has a characteristic by which it is cut off in case of only a small amplitude AC. When a contact ta of a test relay TA is closed and a contact tb of a relay TB is opened under control of a testing device TST, DC is supplied to the telephone set TEL from the testing device TST, and a signal is transmitted through the nonlinear element SV, but when a remote test is executed by closing only the contact point ta of the relay TA, DC is not supplied to the telephone set TEL, therefore, the nonlinear element SV shows the impedance which is nearly infinite, and a transmission characteristic test is executed exactly through the subscriber's circuit SUB by the testing device TST.

摘要： PURPOSE:To make a circuit configuration simple and small-sized by detecting a direction of the two-wire trunk line by means of a photocoupler which has been inserted into the diode bridge, in the outgoing connection trunk for negating a DC magnetic flux. CONSTITUTION:The diode bridges D2-D5 are provided between the primary windings L0, L1 of the hybrid transformer HYB1 connecting the two-wire trunk line side and the switchboard side service line, and the trunk line side, so that one rectifying current only flows into said primary windings, a magnetic flux by the primary winding current is negated by making a current flow into the tertiary winding L3 under the control by the Hall element Ho means, and also it is detected by the photocoupler PCo means which has been inserted and connected in the diode bridges D2-D5. Accordingly, the tertiary winding L3 is enough by one, and also a relay with high sensitivity for supervising the block and release becomes unnecessary.

摘要： PURPOSE:To enable accurate and stable reading-in of bar code at all times, by assuming the interval with the clock corresponding to N-division of interval of bar code equally and reading the presence of bar code signal in the assumed interval. CONSTITUTION:The document 4 is moved toward E and it is scanned toward F with the bar code scanning means 5 consisting of light source, lenses and photo electric converters. In the clock generating means 6, the roller 6a turns and the clock signal having the frequency according to the moving speed is obtained at the output (e). For example, the frequency to divide eight equally the mark interval of the bar code 3 is obtained. The block 7 inputs the bar code scanning signal (d) and the clock signal (e) to output the waveform (f). The block 8 detects the change of 1 0 of the signal (f) and the signal (g) is produced from the pulse of the signal (d), and the block 9 counts the clock with the signal (f) and a signal in which the bar code is not at a given location is produced when the count value between pulse groups exceeds 8.

摘要： PURPOSE:To enable the control of a plurality of objects to be controlled with one timer by on/off control of a plurality of switches corresponding to a value of each bit in a word, read out of a memory one address at a time sequentially for a certain time. CONSTITUTION:An output pulse of an oscillator 2 is counted with a pulse counter 3 to integrate. An arithmetic unit 4 determines that an on/off signal of a switch will correspond to such and such bits at such and such an address of a memory 5 and writes it into the memory 5. The memory 5 is allowed to write and read a signal to turn on or off the number of switches corresponding to the number of bits per one word. A control section 6 reads a binary data at an address of the memory 5 as specified by a value of the counter 3 each time the value varies and converts the bit value thereof into an on/off signal for individual switches to control a switch group S.

摘要： PURPOSE:To reduce a time required for searching an postal number for the operator, by displaying always only an address described on a prescribed position of a mail, at the center of a screen of a cathode ray tube. CONSTITUTION:A mail is carried one by one from left to right, and a video on an address describing part is converted into an electric signal with a scanning section 2. A video storage and operating section 3 picks up only a scanning signal for the address with ''1'' and ''0'' signals and given to a cathode ray tube display section 4 via a signal line 8. The operator 10 reads in a postal number out of the address pictured on the cathode ray tube display section 4 and keys in the number with a keyboard 5. The signal keyed and coded is given to a print mechanism 6 via a signal line 9.

摘要： PURPOSE:To prevent through holes from being plated incompletely by blowing plasma gas, which is introduced from a plasma generator, into the through holes of a printed circuit board. CONSTITUTION:The present invention comprises a plasma gas generator 1 and a processing chamber 3 in which a water repellent resin multilayer printed circuit board 2 is contained. Plasma gas generated in the plasma gas generator 1 is blown through a supply nozzle 6 via a conduit tube 4 and a flexible conduit tube 5 in the processing chamber 3. An X-Y slider 7 to control the position of the nozzle 6 is installed in the processing chamber 3 and automatically controlled with a computer to pass and blow the oxygen plasma gas 9 into all the through holes 8 of the multilayer printed circuit board 2 through the nozzle 6 for the specified time, providing the multilayer printed circuit board 2 with hydrophilicity.
