Title: Hot air heater
Inventor: FUJIWARA YOSHIMITSU
IPC: F24H3/04
Filed: 1988-03-31
Abstract: PURPOSE:To obtain uniform heating in either case of high or low combustion by a method wherein one of air-flow direction control plates at a hot air outlet port is directed more downwardly during a low burning operation than the direction in which the same is directed during a high burning operation. CONSTITUTION:When a burner body 1 works in high combustion, an air-flow direction control plate 14 is directed in a substantially horizontal direction, and high-temperature air is blown forwardly out of a hot air heater, without being blown downwardly. On the other hand, when the burner body 1 works in low combustion, a spring 15 made of shape memory alloy acts so that the air-flow direction control plate 14 is directed downwardly, and a space (30-80cm) on a floor surface can be uniformly heated by hot air at a low temperature and with a small air quantity. Moreover, as substitution for the spring 15, a bimetal may be optionally used. Further, the temperature of the hot air is detected by a thermistor, or pressure is detected by an air pressure switch, to generate a signal for operating a motor, whereby the angle of the air-flow direction control plate 14 may be optionally varied.

IPC: G11B20/12
Filed: 1987-04-01
Abstract: PURPOSE:To eliminate time loss, by performing the inspection of sector arrangement and a sector number in sequence of track sector number. CONSTITUTION:By designating a required interleave format number to a microprocessor MPU1 by an operator at the time of performing the inspection, corresponding interleave arrangement is transferred and stored from a first memory 4 to a second memory 5. Next, the sector number is read out from the second memory 5 in order of address, and simultaneously, a disk driving device 3 is operated by starting up a disk controller 2 for inspection, and a sector equivalent to the sector number out of the sector arrangement of a track is read out. If a fault is generated, it is recognized that a set number is incorrect. Next, the information of the sector from the track is compared with that of the sector number of the memory 4 in order. When an error, etc., is generated, an error defect processing is performed appropriately. By constituting a device in such way, it is possible to eliminate the time loss due to the wasteful rotation of the magnetic disk by performing the inspection in sequence of sector number.

IPC: B22D11/08
Filed: 1978-07-05
Abstract: PURPOSE: To shorten the discard portion of mixture of different kinds of steel and eliminate cause of breakout, by stopping pouring of first molten steel into mold,  and sedimenting circular or polygonal section cold charge having a guide member  into the central position in the mold, then pouring the second molten steel after forming a solidified partition wall.  
     CONSTITUTION: After stopping charge of a first molten steel 2, a cold charge 4 consisting of steel bar having circular or polygonal section is charged. The guide member 4B of the cold charge 4 leads the steel bar 4A easily and exactly into the central position of the mold 1. Since the specific gravity of the cold charge 4 is larger than that of the molten steel 2, is settles down gradually and rapidly forms a solidified layer in he surroundins. This solidified layer is connected with a solidified shell 3 in the molten steel 2, thus forming a partition wall 5 containing the cold charge 4. After replacing the tundish, a second molten steel 12 of different kind of steel beings to be poured onto the partition wall 5. Although the guide member 4B is melted by the molten steel 2, since the partition wall 5 becomes the seam of molten steels 2, 12 and is drawn out, it is enough to dischared the seam part alone. Besides, since the solidified phase becomes continuous, causes of breakout are thoroughly eliminated.

Title: Magnetic disk driver
Inventor: OTSUKA MINORU
IPC: G11B21/12
Filed: 1988-04-05
Abstract: PURPOSE:To prevent destruction of a data by providing an automatic retract device comprising a magnet drive circuit energizing a magnet for a prescribed time through the application or interruption of power supply. CONSTITUTION:With a power supply applied, a magnet 23 attracts a lock part 22 by a magnet drive circuit to release the lock state of a pressing part 21 and a swing arm 4 is driven to move the magnetic head 2 to the outside of the track. In this case, the lock part 22 locks the pressing part 21 again to stop the pressing to the swing arm 4. When power is interrupted due to power failure or the like, the magnet 23 is energized to release the lock state of the pressing part 21 again. Thus, the sliding arm 4 is depressed by the pressing part 21 and the magnetic head 2 is moved to a landing shipping zone 8 of the magnetic disk 1. Thus, even if vibration or shock is exerted as an external disturbance to the magnetic disk driver after power failure, the destruction of data is prevented.
