Title: Permanent magnet type dc machine
Inventor: HINO YOUJI
IPC: H02K23/04
Filed: 1990-11-30
Abstract: PURPOSE:To enable low vibrations and low noises by installing an anisotropic permanent magnet, which controls the direction of magnetic lines of force on molding so as to form a parallel-flux region, in which the magnetic lines of force are changed into parallel and approximately flat magnetic flux distribution within a fixed angle range at the central section of a rotor opposed face, as a magnetic pole. CONSTITUTION:Anisotropic magnets, in which the direction of the magnetic lines of force is controlled on molding, is used as anisotropic magnets 42, 42 functioning as magnetic poles on the stator side. The magnetic lines of force of each magnet 42, 42 are set in the radial direction toward the center of an approximately arcuate circular arc, a parallel-flux region 48, in which the magnetic lines of force 46 run parallel within a fixed angle range at the central section of the magnetic lines of force, and the magnetic lines of force are formed so that effective flux density distribution in the region 48 is kept approximately constant. Accordingly, even when an anisotropic control permanent magnet is employed as a magnetic pole on the stator side, the generation of cogging torque and a torque ripple is inhibited without approximately lowering maximum torque, thus allowing low vibrations and low noises.

IPC: F23N5/24
Filed: 1992-12-22
Abstract: PURPOSE:To perform always a hot water feeding under a correct water level by a method wherein in the case that an occurrence of power failure is detected during a bath sequence, an air removal control is performed after recovering from the power failure state, the operation is returned back to the sequence got at the time of occurrence of power failure. CONSTITUTION:During a hot water feeding control operation, a three-way valve 8 is controlled to a circulating position, a circulating pump 7 is driven, water in a bath tub 5 is circulated in a circulating water passage 3 for 60 seconds so as to discharge air within the circulating water passage 3. Upon occurrence of power failure during this air discharging operation, the three-way valve 8 occupies the circulating position, resulting in that water within the circulating water passage 3 drops. Due to this fact, upon sensing of a flag-on of occurrence of power failure, the air discharging operation is performed again for 60 seconds. After this operation, the three-way valve 8 is set at its closed position, and after a delay of 10 seconds, a signal from a water level sensor 9 is kept as a water level reference value. An one-way transferring of hot water to the bath is carried out while a water level signal got from a water level sensor 9 is being checked. As the water level signal is increased by an amount corresponding to its set water level in respect to the water level reference value, the bath hot water feeding operation is completed and a water draining of a stopper device 16 is performed.

Title: Ink ribbon
Inventor: TANAKA HIDEFUMI
IPC: B41M5/382
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain a halftone image with an extremely high resolution and also an extremely high image quality by using an amount less than a specified value for application of heat melting ink to be applied to the surface of a thin film in a melting- type thermal ink transfer printing system. SOLUTION: In a melting-type thermal transfer device, a recording paper and a thermal head thermal resistance element are closely stuck together, and an ink ribbon ink is transferred to the recording paper by heating the thermal head thermal resistance element under pressure. The surface temperatures of the recording paper are variable depending upon the thickness of an ink ribbon, so that the smaller the thickness of the ink ribbon, the sharper the temperature distribution curve of the thermal resistance element becomes. Therefore, it is easy to control the ink melting area. The thickness of the ink ribbon is determined by a film and an ink applied to the surface of the film.  The film to be used is of the thin film type and the less the applied amount of the ink, the closer the surface temperature distribution of the recording paper becomes to the temperature distribution of the thermal resistance element. Thus the applied amount of a heat melting ink with a single set of plural different colors to be continuously applied to the thin film in its longitudinal direction is set to 2.5g/m<2> or less.
