Title: Electric hot-water apparatus
Inventor: OKABE YOSHIYUKI
IPC: A47J27/21
Filed: 1987-10-26
Abstract: PURPOSE: To enable a smooth pushing-operation while a safety piece against falling-down is provided, by providing the safety piece releasing an abnormal inside pressure in a container to the outside and urging an urging tool for a seal valve stronger than an urging tool for a changeover valve. CONSTITUTION: The second spring 30 for a seal valve 19 is urged stronger than the first spring 27 urging upward a changeover valve 13. When pouring water, the opening motion of a pressurized sending opening 14 by the changeover valve 13 is earlier than the closing motion of an air-suction opening 17 by the seal valve 19, by the pushing manipulation of a pushing body 10, and hence, when the compressed air is sent by a bellows 9, a gap is already formed at the whole periphery between a safety piece 22 to prevent tumbling and a cover 15 and the compressed air is smoothly sent into a container 2. Thus, the pushing pressure is neither temporarily increased nor the front end of the safety piece 22 is pressed on the cover 15, and as a result, a smooth pressing manipulation is made possible and an excellent operability can be secured.

Title: Casting nozzle for steel making
Inventor: TATE MASAHISA
IPC: C04B35/101
Filed: 1984-12-24
Abstract: PURPOSE:To prevent the nozzle clogging arising from the alumina in a molten metal and the change of a casting speed by using a material which forms a low melting compd. by reacting with alumina to form the upper half of a casting nozzle for steel making where the flow rate is relatively low and using a heat resistant material to form the lower part thereof. CONSTITUTION:The upper half of the casting nozzle for steel making where the flow rate is relatively low and the fine Al2O3 in the molten steel is liable to deposit is formed of the CaO-MgO-Al2O3 refractories which form the low melting compd. by reacting with Al2O3. The lower half where the flow rate is high and Al2O3 does not deposit is formed of the alumina or zirconia refractories which are highly resistant to heat and wear and are free from the change of the pore diameter. Such combined nozzle prevents the nozzle clogging and the change of the casting speed and has therefore the longer life.

Abstract: PURPOSE:To correct sensitivity dispersion of a photosensor accurately by provid ing the photosensor to a position at which the sensor interrupts light while a reference white level board is at a read position and the sensor receives light while the reference white level board is at an escaped position. CONSTITUTION:In the case of matching an output level of an optical line sensor 1, a lamp 3 is lighted, a solenoid 6 is driven by a driver and a reference white level board is moved to a read position. The light from the lamp 3 is reflected in a bracket 5 of the reference white level board 4 and focused by a lens 2, reaches the sensor 1 and the output of the sensor 1 is amplified and binarized. Moreover, in the case of reading, the light is shielded, the solenoid 6 is not driven, the light of the lamp 3 is transmitted through a glass 7, reflected in a read medium, focused by the lens 2, the light reaches the sensor 1 and the output of the sensor 1 is amplified and binarized. The output of the sensor 1 is corrected by the output of the sensor 1 reading the reference white level board 4 and multiplied by a prescribed value. Then the dispersion in the output level due to the sensitivity dispersion for each sensor is accurately corrected.
