Title: Designating method of defective minor loop of magnetic bubble memory
Inventor: ANDOU TETSUYA
IPC: G11C11/14
Filed: 1983-03-16
Abstract: PURPOSE:To obtain a magnetic bubble memory device low in error rate and high in reliability by designating minor loops adjacent to checked-out defective minor loop as defective minor loops. CONSTITUTION:For minor loops 1-n-1, n, n+1-m, those circle marks shown in a figure are designated as normal minor loops, and cross marks are designated as defective minor loops. This way of designation is to designate, in addition to a defective minor loop (n) checked out by examination, two adjacent minor loops n-1 and n+1 as defective minor loops. By such a way of designation of minor loops, those minor loops which may heighten the error rate are skipped as defective minor loops and not used. Accordingly, the error rate of the device becomes low and the reliability is made high.

Title: Beam-anneal crystal growth method
Inventor: OONO YASUO
IPC: C30B13/24
Filed: 1984-03-07
Abstract: PURPOSE:To form a single crystal semiconductor thin film with a large area without any grain boundaries by scanning with beams so that the one end of the molten part formed by the beams may be present in the single crystal region formed by the preceding scanning. CONSTITUTION:A region 16 is formed between a trajectory 13 at the side end 11 of the molten part 10 formed by the preceding beam scanning and a trajectory 14 of the point 12 at the rear end of the molten part wherein the normal 22 of a solid-liquid interface starting from the side end 11 coincides with the scanning direction 2 for the first time. The single crystal same as that in the region 15 is formed in the region 16 through the influence of the single crystal in the region 15, and the interface between regions 15 and 16 is not formed. Meanwhile, single crystals are not formed in a region 17 on the other side because the crystal is grown from a polycrystal region 3. Then when the side end 19 of a molten zone 18 corresponding to the side end 11 is allowed to be present between the trajectories 13 and 14 in the succeeding scanning, the single crystal same as that in the region 16 is formed in a region 20, and a grain boundary is not formed between both regions. By repeating said operation, the single crystal region can be extended without forming any grain boundaries.

Filed: 1994-03-15
Abstract: PURPOSE:To prevent the loss caused by a parasitic capacitor by providing an OFF period when a primary switching element is off and besides a current does not flow a secondary diode, and switching the primary switching element from OFF to ON when the voltage across the primary switching element is less than the specified voltage during its period. CONSTITUTION:When a primary switching element 3 is turned off, a secondary current If begins to flow by the energy accumulated in the winding of a transformer 2, and when the energy runs short to the level where it can not charge a smoothing capacitor 5, the secondary current If stops. When the voltage Vc across the primary switching element 3 is less than the specified voltage Vb, the primary switching element 3 is switched from ON to OFF This switches the primary switching element from OFF to ON when a great part of energy accumulated in the parasitic capacitor 10 shifts to the winding of a transformer 2. Accordingly, the energy charged in the parasitic capacitor 10 can be prevented from changing to the short circuit current heat of the energy element 3 during OFF period.

Patent JP-S57157095-A (JP)
Title: Pump with choke preventing means
Inventor: ITOU TAKASHI
IPC: F04D7/04
Filed: 1981-03-24
Abstract: PURPOSE:To prevent choking of a pump due to clogging by foreign matter, by shaping a suction port of a pump casing facing a suction port of an impeller to have an asymmetrically deformed cross section, and thereby off-setting the center of the cross section of the suction port of the pump casing to the center of rotation of the impeller. CONSTITUTION:A suction passage 6a has a circular cross section having a radius r but a portion of the circle is replaced by a straight line drawn at a distance r' from the center of the circle (where r' is smaller than r). When a pump designed as above is operated, the amount of water introduced into the spaces formed between adjacent vanes is changed along the circumferential position due to the off-setting of the center of the cross section of the suction passage 6a to the center of impeller 3, and flow is disturbed at the front of the impeller 3 at its central portion since balance of water flow is lost. Therefore, it is enabled to prevent stagnation of foreign matter since water introduced into the impeller is made to flow gradually outwards in a radial direction while causing  spiral swirl instead of annular flow. Further, since tendency to cause swirl of flowing-in water is suppressed by the function of the deformed cross section of  the suction passage 6a, water drawing efficiency can be increased.
