Title: Wick ascending or descending type petroleum combustion unit
Inventor: ARAI TAKESHI
IPC: F23N5/24
Filed: 1985-04-10
Abstract: PURPOSE:To reliquify non-ignited gasified fuel, accumulate it and prevent bad odor from being generated by a method wherein an air discharging passage in a wick ascending or descending type petroleum unit is arranged in an oil tank. CONSTITUTION:When a wick 13 is descended by operating a knob 9 to turn off the light, an operating part 40 closes a switch 42, a motor 27 of a suction device 26 rotates a suction fan 28 with a cell 43 to cause the air in the wick frame 23 and the tank 10 to be guided into a storing chamber 19 outside of the tank through the flowing-out port 26 or the oil feeding port 15 via the suction pipe 29, tube 32 and the discharging passage 35. The wick frame 23 and the tank 10 show a negative pressure to cause a gasified gas between a small cylinder 21 and an intermediate cylinder 22 to be sucked into the wick frame 23 and the tank 10 and again returned to the kerosene. When the wick frame 23 shows a temperature lower than 100 deg.C, the thermostat 38 is opened to cause the discharging fan to be stopped.

Title: Cleaner for auxiliary transfer-plate in image forming device
Inventor: IKEDA YOSHIMITSU
IPC: G03G15/16
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To lighten and reduce maintenance work and also to prevent a cleaning member from being overdriven and causing imperfect cleaning, by controlling the drive of the cleaning member for an auxiliary transfer-plate based on the drive current and drive time of a driving device. SOLUTION: A cleaning mechanism for an auxiliary transfer-plate 1 is composed of a cleaning member 2, a motor 4 for driving the cleaning member 2, and a spiral shaft 3 connected to the motor 4. Normally, the cleaning member 2 is in an initial position. However, taking account of the case in which a power source is turned off during an operation, or the like, a monitor timer is started first and the motor 4 is CCW driven to perform the operation of returning it to the initial position. At the time, in the DC motor 4 or the like, a start current which is generally equal in current value to a lock current flows for a moment.  When the time needed to detect the lock current is short, the start current is erroneously recognized as the lock current, therefore it is necessary that the time needed to detect the lock current be taken sufficiently longer than the time during which the start current flows. In the case the lock current is detected, the device recognizes that it reaches the opposite side.

Filed: 1990-03-26
Abstract: PURPOSE:To simplify the adjustment of pressure and hold pressure for a long time by forming a comparison pressure room to allow pressure to be adjusted to preset pressure later by a pressurizing member from the outside. CONSTITUTION:A comparison pressure room 13 is formed so that pressure therein is somewhat higher than switch operating pressure and by using air tight material which can be held for a long time from the beginning. A pressurizing member 16 for adjusting pressure in the comparison pressure room 13 to preset operating pressure from the outside is formed in a disc, e.g. threaded by a screw to the inner-periphery edge of the cylindrical portion 11a of a switch mainframe 11. The pressurizing member 16 is rotationally moved while threading the peripheral edge thereof in such a state that preset operating pressure is applied to a diaphragm 12, and stopped at a position where a contact member 14 performs contact operation. It is thus possible to simplify adjustment to preset pressure.

Title: Multivalue drive circuit
Inventor: OKAYASU TOSHIYUKI
IPC: G01R31/28
Filed: 1990-03-26
Abstract: PURPOSE:To enable generation of multivalue waveforms of high speed and large amplitude by constructing the title circuit of a plurality of voltage sources outputting voltages being different from one another, a diode switch circuit and a plurality of current switches. CONSTITUTION:A plurality of voltage sources 15 to 17 output voltages being different from one another. A diode switch circuit 14 selects and takes out the voltage of any one of these voltage sources 15 to 17, and a purality of current switches 10 to 13 control switch elements of the circuit 14 to turn ON and OFF respectively. Since the structure wherein the voltages each taking a multiple value are generated beforehand from the voltage sources 15 to 17 and these generated voltages are selected and taken out by the circuit 14 is adopted, it is unnecessary to control a large current intermittently for generating a voltage of large amplitude. Since it is needed only to control intermittently ON/OFF of the switch elements constituting the circuit 14 by a relatively small current, in other words, the intermittent control can be executed at a high speed. Since necessary voltage values are generated beforehand in the voltage sources 15 to 17 in a plurality, besides, a voltage waveform of large amplitude can be obtained with ease.

Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a recessed impression upon press- molding a steel sheet after cleaning by cleaning the steel sheet by use of a clean cleaning solution whose dust containing amount is limited by the number of dust particles. SOLUTION: A steel sheet 1 is cleaned by using a cleaning solution 19 whose dust containing amount is limited by the number of dust particles, which is cleaner than a conventional cleaning solution when injecting the cleaning solution 19 onto a surface of the steel sheet 1 and cleaning dust adhered to the surface. It is necessary to measure the number of dust particles. For example, if the dust is a clean sample of a small amount, it is put into a transparent container and light transmission results in easy measuring of the number of particles. An existing counting device for optically counting the number of particles may be used. Further, although means for cleaning the cleaning solution 19 is not particularly limited, the cleaning solution 19 just before supplying to a spray nozzle 3 may be passed through a filter whose sieve meshes are proper.
