Title: Uninterruptible power supply apparatus
Inventor: WAKABAYASHI TOMOTAKA
IPC: H02M7/06
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain an uninterruptible power supply apparatus in which a higher harmonic component flowing out to a system is removed, by a method wherein a storage battery is charged by a second converter and the higher harmonic component generated by a first converter is controlled so as to be offset. SOLUTION: In an ordinary operation, a first converter 5 rectifies power from a system, and the rectified power is inputted to an inverter 3. Then, the inverter inverts the supplied power into an alternating current so as to be supplied it to a load. In addition, at this time, a second converter 6 charges a storage battery 4, higher harmonics whose phase is opposite to that of, and whose value is identical to that of, higher harmonics which are detected by a current transformer 7 and which are generated by the first converter 5 are generated, and higher harmonics on the input side of an uninterruptible power supply apparatus are removed. In the power failure of the system, DC power from the storage battery 4 is inverted into AC power by the inverter 3 so as to continue the supply of electricity to the load.  As a result, the capacity of the second converter 6 can be reduced, and higher harmonics which flow out to the system can be removed.

Title: Sheet supplying device
Inventor: HANBA GOROU
IPC: B65H3/06
Filed: 1983-04-07
Abstract: PURPOSE:To ensure that a sheet can be supplied by utilizing a rotating force of a platen provided on the side of a business machine, by a construction wherein a sheet is supplied by transmitting a rotating force of a platen to a separating roller, and the separating roller is pressed against the surface of the sheet only when the platen is rotated reversely. CONSTITUTION:The sheet 57 set in a stand-by condition in which the lower end thereof makes contact with the platen 13 and a pinch roller 14 is drawn between the platen 13 and the pinch roller 14 simultaneously with the start of rotation of the platen 13, and is so fed along a paper guide 15 as to be wound around the outside periphery of the platen 13 by the rotation of the platen 13. Rotatable levers 32a, 32b are rotated by using cranks 46a, 46b, whereby the separating roller 34 is selectively pressed against the surface of the sheet 57. By this, the rotating force of the platen 13 can be transmitted to the roller 34 irrespectively of the direction in which the platen 13 is rotated. Since the roller 34 is pressed against the surface of the paper 57 only when the platen 13 is rotated reversely, drawing-out and insertion of a sheet holding cassette 55 at the time of supplying the sheet or the like can be easily performed without requiring any operation for separating the roller 34 away from the surface of the sheet.

Abstract: PURPOSE:To improve the thermal efficiency of an incinerator, by a method wherein combustion  air is fed from a lower part of the subject incinerator at an excretion-processing site, and a part in the proximity of an exhaust port is held in a negative pressure by means of an exhaust gas discharge control, and an auxiliary blast amount is adjusted at a combustion stage where the maximum temperature is shown. CONSTITUTION:Dehydrated sludge, charged through a sludge charging port 12, is transferred, in  order, to lower stages, and is dried on a drying belt 4 for the combustion on a burning belt 8. A  pressure in the proximity of an exhaust gas exhaust port 17 is detected by means of a pressure  detector 26, and an opening angle of a control valve 19 in an exhaust gas line 18 is regulated so  that a constant negative pressure is always held. Temperature detectors 29-31 are placed at  stages 5-7, resectively, in the burning belt 8, and the output is inputted to a discriminator 32.  The discriminator 32 discriminates what step has a maximum temperature, and control valves 35,  37, and 38 are controlled through the working of a regulator 39 to a just hot blast amount, produced by the use of auxiliary fuel, to the combustion stage 7. This supplies a combustion air  amount corresponding to physical properties of a combustion substance and to a change in  amount, and enables the improvement of an efficiency.

Title: Magnetic recorder
Inventor: KIMURA KAZUO
IPC: G11B5/02
Filed: 1984-03-29
Abstract: PURPOSE:To ensure the assured postrecording with the sound signal only with no deterioration of the reproduced picture quality, by setting the level of a recorded sound within a range between a level at which no mixture occurs with a recorded signal and a level at which no deterioration is caused to a reproduced picture. CONSTITUTION:For instance, an audio head having 27mum width and 0.5mum gap width is used with a magnetic tape having 670 ersted reluctance force. Under such conditions, a characteristic diagram between a sound signal recording level and a reproducing level is roughly shown. No sound signal is recorded when the sound signal is lower than a level l1. The sound signal is mixed with a recorded signal when it has a level close to l2, and the video signals on a surface layer are partially erased when the sound signal level is higher than l3. Therefore the optimum recording level is limited to 12-15mA between levels l1 and l2 without causing deterioration of the reproduced picture quality not mixing record. Thus the postrecording is facilitated by recording the sound signal within said range. In this way the range of application of a magnetic recorder is increased.
