Title: Transient rectification improving method of dc machine
Inventor: NAGATA TOYOKAZU
IPC: H02P7/29
Filed: 1984-08-24
Abstract: PURPOSE:To improve the transient rectification at load varying time by controlling a speed signal from a tachometer generator and a current flowed to a variable current branch circuit in response to the differentiated value. CONSTITUTION:A variable current branch circuit which is composed of a series inserting reactor 8 in parallel with both or either one of compensating winding 2 and an interpole winding 3, a parallel capacitor 8 and a semiconductor chopper type variable current branch unit 10 is provided.

Title: Hot water supplying device
Inventor: IWANAGA SHIGERU
IPC: F24H1/00
Filed: 1983-09-21
Abstract: PURPOSE:To ensure the safety on water quality by closing stop valves provided in water pipe lines and consequently preventing heat transfer medium from mixing in a hot water storage tank in a case that a hole is formed by some rare accident on the heat transfer wall of a heat exchanger for hot water supply by a structure wherein a water circulating path is formed by connecting the hot water storage tank, a circulating pump and the heat exchanger for hot water supply and stop valves are respectively provided in water pipe lines on the upstream side and downstream side of the heat exchanger for hot water supply. CONSTITUTION:When a hole is formed by some rare accident on the heat transfore wall of a heat exchanger 2' for hot water supply, the presure in a low pressure circuit falls down during heat pump operation and the abnormally low pressure is detected by a pressure sensor 20. Or the abnormal rise of water pressure is detected by a pressure sensor 21 arranged in a water pipe line 9b. When the abnormality is detected by the pressure sensor 20 or 21, a motor operated valve 16 is closed and consequently heat transfer medium is prevented from flowing into a hot water storage tank 7. On the other hand, a check valve 15 arranged in a water pipe line 9a on upstream side prevents the water from flowing backwards into the hot water storage tank 7. In such a manner as mentioned above, because the heat transfer medium is prevented from flowing into the hot water storage tank, the safety on water quality can be ensured.

IPC: H01L21/68
Filed: 1991-06-21
Abstract: PURPOSE:To make possible the positioning of a microscopic step by a method wherein in the case the positioning of an object to be transferred is not completed within an allowed time, oil at the contact part of the object is in between the guide of the contact part and a frame from the periphery of a targeted position, an oil film at the contact part is returned to the initial state and the object is again positioned. CONSTITUTION:When an object to be transferred is driven, the state of a friction contact part of the object is decided and when the state of the contact part is decided that the state is bad, the object is first made a long-stroke drive from a prescribed position and after that, is positioned at a targeted position. In such a way, when the state of the contact part is bad, such as in the case the positioning of the object is not completed within an allowed positioning time, the drive path of the positioning is made long, whereby oil is primed in between a guide 6 of the contact part and a frame 7 from the periphery of the targeted position by a wedge effect, an oil film at the contact part is returned to the initial state and the object is again positioned in this state. Thereby, the positioning of a microscopic step can be performed.

CPV generator circuit 16 generates successive two pulses every time the horizontal synchronizing signal is added in the upper and lower fields A and C, on which a specific picture of each line is displayed, and also generates a shift clock CPV synchronized with the horizontal synchronized signal after thinning out specific lines corresponding to the number of display lines on the fields A and C, in case of generating images of the central field B.  OEV generator circuit 17 generates line-enable signals OEV to drive two lines successively on the fields A and C, and also generates a signal by which the line-enable signals OEV1 to OEV3 are changed to 'active' sequentially at the scanning of the field B.

Abstract: PURPOSE:To provide a toner which is less dependent on environment, exhibits stable controllability of electric charge and has good fixability, magnetic characteristic and durability by using a specific copolymer as a binder. CONSTITUTION:A copolymer of 1 or >=2 kinds of monomers having the amino group expressed by the formula (R1 is H atom or lower alkyl group, R2 is 0-12C alkylene group, R3, R4 are H atom, lower alkyl group or phenyl group) or the quaternary ammonium salt thereof and other vinyl groups is incorporated as a binder for an insulating toner into said toner. Such insulating toner is coated on a toner carrying body 2 of a latent image holding body 1 and toner carrying body 2 which are disposed apart from each other at a specified space in a developing part. The toner is thus conveyed to the developing part where the toner is subjected to developing while receiving an alternating electric field for the toner. The toner which contains the above-mentioned copolymer as a binder and is used for such developing system exhibits good and stable controllability of electric charge and is less dependent on environment owing to the low moisture absorptivity. The toner has excellent durability in copying of multiple sheets and has good magnetic characteristic and fixability when used as a magnetic toner.

Filed: 1987-07-15
Abstract: PURPOSE:To simplify a shading correction device by storing luminous pattern data which corresponds to a printing lens in a storing means, displaying the selected luminous pattern on a CRT corresponding to a lens to be used. CONSTITUTION:At the time of using the printing lens 7, a selector 33 is connected to a contact point (a) and the data of the luminous pattern stored in a frame memory 30 is read out and inputted into a driver 35.

IPC: F23C99/00
Filed: 1989-07-07
Abstract: PURPOSE:To recycle the discharged gas so as to reduce the NOx emission by drawing steam and combustion gas inside a furnace into a combustion cone by a method wherein steam is ejected from a steam injector into the combustion cone in such a manner as to produce a negative pressure and draw the surrounding gas inside the furnace. CONSTITUTION:Steam injectors 8 are arranged in a concentric row in the side wall of a combustion cone 3. Each of the steam injectors 8 is connected to a steam pipe 7. At the center of the combustion cone 3, a burner nozzle 4 is placed and a flow-straightening plate 5 at the forward end thereof. Through the steam pipe 7 and a solenoid valve 6 for steam, steam S is fed to each of the steam injectors 8 and ejected into the combustion cone 3 in such a manner as to produce a negative pressure and draw through a suction hole 8a in the steam injector 8 the surrounding gas G inside the furnace into the combustion cone 3 together with the steam S. That is to say, recycled feeding of discharged gas becomes possible simultaneously with the ejection of steam. As a result, the flames become split, the combustion temperature decreases effectively, the rate of the combustion slackens, and the NOx emission can be reduced.
