Title: Electromagnetic induction heating cooker
Inventor: OGASAWARA TOSHIO
IPC: H05B6/12
Filed: 1994-04-15
Abstract: PURPOSE:To heat a cooker optimally from pan heating range to high- temperature hot plate range by optimizing the electromagnetic induction heating by the structure of a vessel for heating. CONSTITUTION:A vessel 9 for heating, where the opposite side from the induction coil consists of a magnetic material and the layer on it consists of a nonmagnetic material, is placed on the top plate 1, and is supplied with a current by the induction coil 3 below it, and further the set temperature is properly selected and controlled by varying the distance between the vessel 9 for heating and the induction coil 3 properly. Hereby, using the vessel for heating where SUS 430 material not optimum for the electromagnetic induction heating is used, at the time of heating the pan itself, maximum efficiency is obtained with the maximum coupling by bringing the distance between the vessel for heating and the induction coil close to each other, and suppressing the temperature to '100 deg.C', etc. While, at the time of '260 deg.C', etc., the distance between the vessel for heating and the induction coil is enlarged, whereby the radiant heat of the vessel for heating is lightened, thus an efficient electromagnetic induction heating cooker, which does not give excessive stress to the switching element, can be gotten.

Title: Magnetic brush type cleaning device
Inventor: MORI IKUO
IPC: G03G21/10
Filed: 1981-05-22
Abstract: PURPOSE:To eliminate the evil effect on a copy, by setting a magnet which generates small and large magnetic fields at the specific positions to form a specific magnetic pattern and accordingly increasing the eliminating efficiency of the toner particles as well as minimizing the scattering of the residual toner. CONSTITUTION:The fixed magnets 20-26 are distributed radially within a rotary sleeve 4 so as to be adjacent to the inner surface of the sleeve 4. Thus the magnetic carrier particles 3 are formed into a brush-shape. As a result, a strong magnetic field is generated from a magnet 20 at the position closest to a cleaning region 11, a magnet 21 at the position 13 where the toner particles 2 and the carrier particles 3 are supplied and a magnet 22 at the position near a toner particle removing roll 9 respectively. Other magnets 23-26 generate the the weak magnetic fields. The magnets 20-26 are distributed with the prescribed angles theta1-theta7 respectively to form a specific magnetic pattern. The particles 2 which are absorbed to the particles 3 at the region 11 are held on the surface of the sleeve 4. This holding force does not exist at all in an exfoliation region 14 where the same magntic poles are set adjacent to each other. As a result, the particles 2 drops into a housing by gravity.

IPC: F23N3/04
Filed: 1987-03-31
Abstract: PURPOSE:To prevent condensate from forming in the exhaust pipe by preventing the exhaust gas temperature from becoming reduced even at low burning intensity disposing a shutter in a part of a passage in a secondary heat exchanger so that part of the passage in the secondary heat exchanger may be closed off under a certain temperature. CONSTITUTION:A secondary heat exchanger 4 has a main passage 4a and a bypass 4b, and a shutter 6 and a spring 7 to open or close the shutter 6 are disposed at the outlet of the bypass passage 4b. The spring 7 is made of shape memory alloy, and close off the bypass passage 4b by pushing the shutter 6 when the allowable temperature for the exhaust gas condensation is reached while burning at low intensity. Therefore, the exhaust gas flows only through the main passage 4a and is expelled out of the exhaust gas pipe 5, resulting in the reduced heat exchanging efficiency and the increased exhaust gas temperature to prevent condensation in the exhaust gas pipe 5.

Abstract: PURPOSE: To assure sufficient strength and workability even if a unit cement quantity relating to a temp. stress is decreased by decreasing the unit cement quantity and compounding a high-performance water-reducing agent or the high-performance water-reducing agent and welan gum. CONSTITUTION: The unit cement quantity is made smaller by >=10kg/m<3> than the design compounding and the high-performance water-reducing agent, such as β-naphthalene sulfonnate, etc., is compounded at 0.01 to 0.1wt.% and the welan gum at 0 to 0.1wt.% of the unit water volume, by which the unit cement quantity is decreased to <=210kg/cm<3> and the unit water volume for obtaining prescribed slump is decreased by 5 to 10kg/m<3> at the time of producing dam concrete by mixing the necessary unit cement quantity under compounding design of the slump value of 0 to 6cm to obtain the dam concrete having the target strength. As a result, the water cement ratio does not increase and the compressive strength does not degrade even if the unit cement quantity is decreased by about 10 to 20kg/m<3> .  The degradation in viscosity is suppressed and the cost reduction is attained by addition of an admixture (high-performance water-reducing agent + welan gum).
