Title: Carbon-containing refractory
Inventor: TSUCHIYA ICHIRO
IPC: C04B35/66
Filed: 1993-12-16
Abstract: PURPOSE:To obtain a carbon-contg. refractory retaining its excellent resistance to spalling and corrosion and improved in oxidation resistance. CONSTITUTION:This carbon-contg. refractory is obtained by incorporating 0.5-10wt.% of aluminum borocarbide in a refractory material comprising 65-95wt.% of a refractory aggregate and 5-35wt.% of a carbonaceous material. Incorporation of the aluminum borocarbide causes its reaction with the oxygen in the atmosphere on the surface of the refractory during its use to produce alumina and boron oxides which melt at about 450 deg.C and cover the refractory surface, thus preventing the oxidation of the carbonaceous material from relatively low to higher temperatures. Furthermore, reaction between the alumina and the boron oxide raises the viscosity of the melt, the surface of the carbonaceous material is covered with this melt more firmly esp. at >=1300 deg.C, thus preventing the oxidation of the carbonaceous material; besides, the surface of the carbonaceous material is covered with a compound produced by reaction between an excess of the boron oxide and the various components of the refractory to effect prevention of the oxidative burn-off of the carbonaceous material, thus obtaining the objective carbon-contg. refractory retaining its resistance to corrosion and spalling and improved in oxidation resistance.

CONSTITUTION:A brush 14 with specific width as the flocked member is mounted on the side of the recording paper conveyance path at the end part of an upper guide 13U on the side of a transfer part 7 over the entire width- directional area of fan fold paper 20. In the printing stand-by mode, the fan fold paper 20 is stopped from being conveyed and released from being pressed against the side of a photosensitive drum 1, and the constant-speed conveyance is stopped abruptly, so that the fan fold paper 20 slacks between a photosensitive drum 21 and a corona charger 71 because of the inertia. The filling member of the brush 14 at this time is released from being tensed when the fan fold paper 20 slacks and returns to its straight state, thereby retreating the fan fold paper 20. Consequently, the continuous paper can securely be retreated from the photosensitive drum in the printing stand-by mode.

Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a concentrated winding brushless DC motor for preventing a bundle of coils at a coil end from sticking out inside a stator through stress of the coil when the coil is turned on a stator core. SOLUTION: In a brushless DC motor, a tooth part 12 of a stator core 1 has a shape, in which a bottom width (A) of a slot bottom part is made smaller than an inner width (B) of an inner diameter side part, so a lower-layer coil turned in a shape like a fan toward an inner diameter side of a stator has a tendency of moving force to a slot bottom. Then, useless stress is not applied to the coil when a driving coil is turned on a tooth part of the stator core, and a bundle of coil at a coil end is prevented from sticking out in a stator inner diameter side, and high quality can be kept.

Filed: 1993-12-20
Abstract: PURPOSE:To dispense with surface treatment of a body to be inspected and to make it possible to execut flaw detection with high sensitivity by providing a plurality of transmission/reception coils divided electrically and by switching over the coils electrically for scanning. CONSTITUTION:Transmission/reception coils 5 are divided into two transmission/ reception coil groups and provided at symmetric positions on the opposite sides of a welded part W of a metal 4 bring a body to be inspected. Since the equipment is of an electromagnetic type, surface treatment is dispensed with basically and, in addition, a probe can be removed simply from the surface of the body 4 to be inspected by interrupting an exciting current, while a magnetic flux density can also be increased. Since an angle of refraction of an ultrasonic wave propagated through the body 4 to be inspected is determined by the relation between a coil pitch and a frequency, moreover, a desired frequency can be set according to setting of the coil pitch. Since the coils 5 are juxtaposed in the direction intersecting the direction of propagation of the ultrasonic wave perpendicularly to it in addition, scanning can be executed with the juxtaposed coils 5 switched over electrically, and therefore flaw detection over a wide range can be executed without being accompanied by mechanical movement.
