Filed: 1985-07-17
Abstract: PURPOSE:To enable to correct the change in the height of a printing character due to the change in temp., by providing a temp. characteristic to charge voltage charging an ink droplet. CONSTITUTION:The deflection amount of an ink droplet increases as temp. becomes high and, as a result, the height (h) of a character increases. Contrarily, a negative temp. characteristic is provided to charge voltage V to correct the temp. characteristic of the height of the character. For example, in an electric circuit, a D/A converter 14 converts the n-bit input signal from a control part 12 to an analogue current signal which is, in turn, converted to a positive voltage signal by a resistor 15 and an operational amplifier 17. This voltage signal is amplified by an operational amplifier 20 and a transistor 24 and outputted as a straight polarity voltage signal by a clamp circuit constituted of a condenser 25 and a diode 26. Now, if a resistor 22 is constituted of a temp. sensitive resistor having a proper negative temp. characteristic, a negative temp. characteristic can be provided to the gain of a circuit.

Title: Decision system for incomplete call
Inventor: KANEKO OSAMU
IPC: H04M3/36
Filed: 1981-10-07
Abstract: PURPOSE:To record data on an incomplete call economically, by deciding that a call is an incomplete call through a call recording device on the basis of the time length of a pseudo call signal, and then performing prescribed recording regarding it. CONSTITUTION:To the signal line from a call connecting trunk ICT to a call recording device OCM, a pseudo answer signal shorter than a prescribed time is sent out when an optional call is disregarded before a called subscriber answers. The device OCM decides on an incomplete call from the continuation time of said pseudo answer signal. The completion time is regarded as abandoned time and data on that is recorded through a magnetic tape device MTS. Thus, even the incomplete call is recorded without increasing the number of signals lines between many trunks ICT and the device OCM in a telephone exchange. Therefore, call recording of the telephone exchange is performed economically and accurately.

Title: Earth-leakage breaker
Inventor: ISHIGAMI YOSHIHISA
IPC: H02H3/16
Filed: 1988-06-27
Abstract: PURPOSE:To obtain an earth-leakage breaker which alarms earth leakage to a user then interrupts the power source by producing an alarm prior to interruption of the power source upon occurrence of leak current. CONSTITUTION:A leak current is detected through a zero-phase current transformer 2CT and a capacitor C1 is charged when the input voltage of an IC 1a exceeds over the reference voltage at an amplification/comparison section 3. A comparator 6 produces an output when the voltage across the capacitor C1 reaches to the reference voltage of the comparator 6. The output is converted into an output which is held in a one-shot circuit 7 for a predetermined time, and a pre-alarm is produced from an alarm circuit 8. At the same time, a transistor Q1 is turned ON and a resistor R3 is connected thus lowering the input voltage of the IC 1a. When the input voltage reaches to the reference voltage of the comparator 6 in the amplification/comparison section 3 under this state, SRPQo is turned ON to trip an earth-leakage breaker.
