Patent JP-S573263-A (JP)
Title: Stopping method of magnetic disk storage device
Inventor: NISHI KENICHI
IPC: G06F3/06
Filed: 1980-06-09
Abstract: PURPOSE:To prevent stored information on a disk from disappearing by stopping a disk device right after sensing a P wave of an initial slight shock of an earthquake. CONSTITUTION:While a P-wave sensor 22 senses no P wave, normal damping is applied to a motor 18 via a brake 19 with the output 23 of a control circuit 1. When it senses the P wave, on the other hand, a brake controller 21 outputs a prescribed damping signal with the output 24 of the control circuit 1, and the motor 18 decreases its turning speed rapidly and stops.

Title: High density sintering of lanthanum chromite doped with alkaline earth metal
Inventor: YASUDA ISAMU
IPC: C04B35/42
Filed: 1992-02-28
Abstract: PURPOSE:To sinter the lanthanum chromite into a high density by sintering the non- sintered molding of the lanthanum chromite doped with an alkaline earth metal in a state that prescribed metals and their oxides coexist. CONSTITUTION:Aqueous solutions of nitrate salt of La, Sr and Cr are mixed with each other in a prescribed ratio, subjected to an ultrasonic spraying into a reaction tube in an electric oven kept at 500-1000 deg.C for instantaneous pyrolysis of the nitrates to obtain the powder of the lanthanum chromite doped with the Sr. The powder is mixed with an organic binder and a solvent and subsequently granulated into uniaxially press-molded green molding. The molding is embedded in mixed powder 2 (e.g. the mixture of Cr with Cr2O3 in a molar ratio of 2:1) in an inside aluminum container 3, and the inside aluminum container is received in an outside aluminum container 4. The containers 3, 4 are inserted into an electric oven and sintered at approximately 1600 deg.C for about 3hrs. The sintered compact has a density approximately two times as high as that of a sintered compact produced by sintering the raw materials in air under the same conditions. The employment of the sintered compact as the separator of a solid electrolyte type fuel battery prevents the cross leakage of gases and improves the efficiency of the battery.

CONSTITUTION:A support roll 10 used in hot-dip zinc plating rotated so as to be immersed in or contacted with the molten zinc in a plating bath tank consists of a roll main body 12 having a concentric piercing bore 12a in the axial direction thereof an shafts 14, 15 for supporting said roll main body 12 at both ends thereof. In this case, the shafts 14, 15 support the main body 12 at both ends thereof through disc shaped bushes 16, 17. In addition, the parts of the shafts 14, 15 externally extending from the fixing places with the bushes 16, 17 for bearing support parts and the free ends thereof extending into the piercing bore 12a are opposed at the almost center part of the main body 12 so as to leave a slight gap therebetween. Because rings 20, 21 welded to the outer peripheral parts of the free ends are inlaid with the main body 12 in a slidable manner and the free extension and retraction of the shaft free ends are possible, heat stress does not remain in the roll 10.

Title: Disk tray driving device
Inventor: TERAOKA MASATO
IPC: G11B17/056
Filed: 1985-04-15
Abstract: PURPOSE:To lower the noise during driving a disk tray and perform the driving of the disk tray with high reliability for a long use by providing an electromagnetic solenoid generating a driving force for moving the disk tray. CONSTITUTION:When a direct current passes through solenoid coils 14a, 14b wound on both ends of a slide guide 12 and an N pole and an S pole are excited, the direct current passes through a coil 11 wound on a body of an electromagnet carriage 10 and an end of the carriage 10 is excited as the N pole and the other end is excited as the S pole. Thereby the carriage 10 is moved rightward and a disk tray on which the carriage 10 is mounted is also moved to the same direction. When the direction in which the direct current passes is opposite, the moving direction of the tray 1 becomes opposite. In this way, the noise during driving can be lowered and the drive with a high reliability for a long time use can be done.

IPC: H04B10/556
Filed: 1989-03-31
Abstract: PURPOSE:To surely detect the fault of an optical transmission line by using a complementary code bit corresponding to the specific order bit of an information bit to send a data and receiving the data by using a complementary code bit corresponding to the bit of a different order from the specific order bit of the information bit. CONSTITUTION:The transmission is implemented by using a complementary code bit M' corresponding to a specific order bit M in information bits 1-8 and the reception is implemented by using a complementary code bit N' corresponding to the bit of a different order from the specific order bit M in the information bits 1-8. Then the fault of an optical transmission line is detected by the reception of the complementary code bit corresponding to the specific order bit. Thus, the order of the information bit corresponding to the complementary code bit differs between the transmission and reception and the fact that a transmission optical signal reaches as a reception optical signal is discriminated surely. Thus, the fault is detected.
