Title: Thermal transfer printer
Inventor: KATO TAKESHI
IPC: B41J2/325
Filed: 1986-04-11
Abstract: PURPOSE:To take-up an ink ribbon under constant tension without being affected by the size of the take-up reel diameter of the ink ribbon, by receiving the position detection signal of the ink ribbon outputted from a detection part for detecting the take-up tension of the ink ribbon to appropriately transmitting said signal to an ink ribbon driving motor. CONSTITUTION:When ink ribbon 11 is not taken-up, a position detection pin 14 is pushed to the end part of a slot 27 in a B-direction by an elastic member 15 but, when the ink ribbon 11 is taken-up, said pin 14 moves to a C-direction to be changed to a position where the tension of the ink ribbon is well-balanced with the energizing force of the elastic member 15 corresponding to said tension. The displacement of the position detecting pin 14 is detected as the voltage signal of a position detection signal F by a potentiometer 29. The position detection signal F of the potentiometer 29 is inputted to one input terminal of the differential amplifier 21 of a control part 20 and a reference position signal H is inputted to the other input terminal thereof. A drive motor 12 is driven in a direction, wherein the difference between the position detection signal F and the reference position signal H becomes 0, by the control part 20.

Abstract: PURPOSE:To smoothly supply multi-kinds parts in a small space, by detecting the kinds of parts on a subline to store the same into a predetermined storage lane in a predetermined order, and by supplying parts from a predetermined lane in accordance with the kind of parts on a main lane. CONSTITUTION:The kind of parts on a subline 1 is detected by a part kind discriminating device 16 from which an output signal is delivered to a control device 18 that is therefore, determines parts to be fed into a storage lane 20, and therefore, operates a robot 24 for the lane. Meanwhile, when the kind of articles on a main line 28 is detected by an article kind discriminating device 30 which delivers a flowing article kind signal to the control device 18, the control device 18 determines a storage lane 20 from which parts required for the kind of articles are delivered, and a high speed robot 24 in charge is driven. Therefore, the robot 24 takes out the parts in a pallet onto a discharge lane 22. With this arrangement it is possible to smoothly supply parts in a small space.

Title: Direct current restoration circuit
Inventor: ANZAI SHOZO
IPC: H04L25/52
Filed: 1985-04-19
Abstract: PURPOSE:To reduce error data which are generated for longer than a dropout generation period by providing an amplitude limiter on a path for feeding the output signal of a low-pass filter forward to the threshold voltage input terminal of a comparator. CONSTITUTION:When the output voltage of the low-pass filter 5 drops below a specific voltage value owing to the generation of a drop-out, the amplitude limiter 6 reduce the output voltage, and consequently the threshold voltage value fed forward to the comparator 3 becomes low. Namely, the amplitude limiter 6 feeds the output voltage of the low-pass filter 5 forward to the inverted input terminal 3b of the comparator 3 through a resistance R3 to compensate a DC component and also turns on a transistor Q1 or Q2 when the output voltage of the low-pass filter 5 exceeds the specific voltage value to reduce the value of the voltage fed from the resistance R3 to the inverted input terminal 3b of the comparator 3. Consequently, when an input signal is inputted, again, DC restoration operation is performed immediately and error data are reduced.

Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To supply an AC input current with power factor of 1, while preventing trouble due to harmonic by on/off controlling a switching circuit to form an AC current, while following up a reference signal, i.e., an input AC power supply voltage thereto. SOLUTION: At the switching of circuit operation for each power element in a switching circuit 10, AC error amplifiers 11u, 11w generate control outputs such that a feedback signal, i.e., the waveform of an AC input current, follows up a reference signal, i.e., the waveform of a power supply voltage. For example, when the AC input current is lower than the AC power supply voltage, pulse width is regulated to prolong the on-state of the switching circuit and the waveform can be matched between the AC power supply voltage and the AC input current. In other words, a converter having power factor of 1, i.e., the frequency and phase match between the waveforms of AC power supply voltage and AC input current, and hardly generating no harmonic can be obtained.

Title: Method for suppressing sulfide formation by sulfate reduction bacterium
Inventor: TSUCHIMOCHI YUICHI
IPC: C02F11/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To rapidly suppress sulfide formation by sulfate reduction bacteria by adding an anthrahydroquinone compound to a water system in treatment equipment for factory waste water, municipal sewage, etc., where the sulfate reduction bacteria exist. SOLUTION: The sulfate reduction bacteria existing in the water system form sulfide by reducing sulfuric acid ions under an anaerobic atmosphere. The sulfide is discharged as hydrogen sulfide to a gaseous phase which is made into sulfuric acid by the effect of sulfur oxidation bacteria on the surface of concrete or metallic materials to lead the corrosion of the concrete or metallic materials. An anthraquinone compound is reduced to the anthrahydroquinone compound which is then added to the water system in order to suppress the trouble, such as corrosion and malodor, by such sulfate reduction bacteria, by which the formation of the sulfide by the sulfate reduction bacteria is rapidly suppressed. The concentration of the addition of the anthrahydroquinone compound is specified to >=5 mg/liter of the sewage to be added therewith and to >=20 mg/liter of the sludge to be added therewith.
