Title: Improvements in or relating to ferroresonant flip-flop circuits
IPC: H03K23/76
Filed: 1954-04-05
Abstract: 751,401. Non - contact - making relays. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 5, 1954 [April 8, 1953], No. 9887/54. Class 40 (4). In a ferroresonant circuit comprising resistance R, capacitance C and saturable inductance L connected in series across an A.C. source Eac, a trigger winding T is magnetically coupled to the inductance so as to produce a flux at right angles to the normal flux, whereby the circuit has bi-stable operating conditions without magnetic coupling between the trigger and inductance windings except during those periods in which both windings are energized. The inductor core material may be formed of thin magnetic ribbon 10 which in the arrangement shown in Fig. 8 is double-folded along the axis of grain orientation and is utilized as a trigger winding by welding or soldering a conductor 11 to its ends. Alternatively conductor 11, Fig. 9, constitutes the trigger winding and is positioned at the centre of a cylindrical roll of the core material. A single layer A.C. winding 12 is either directly wound on the core or is carried on an interposed section of sleeve insulation 13, Fig. 10. Two ferroresonant circuits may be arranged in parallel as shown in Fig. 3 and connected to the A.C. source through a common impedance Z which may be constituted by a resistor or inductive or capacitive reactance, the arrangement being such that pulses in the trigger windings T1, T2 cause the two circuits to change in opposite respects from one stable condition to the other. In a modified arrangement, Fig. 11, the trigger windings T1, T2 are connected to a single pulse input circuit and separate rectified and smoothed outputs are obtained across condensers C1, C2. As the common impedance Z is constituted by a capacitor 23, the D.C. output circuit is completed by an earthed resistor 24. Suggested applications are to counting circuits and shifting registers.

Title: Method of forming laminated single polarization fiber
Inventor: BHAGAVATULA VENKATA ADISESHAIA
IPC: G02B6/10
Filed: 1988-12-22
Abstract: A process for manufacturing a preform from which is drawn an optical fiber, the core of which comprises layers of different glass composition. Layers of glass soot are deposited on the flat, longitudinally extending sides of a thin, elongated mandrel. Adjacent soot coatings have different refractive indices. A preliminary coating of cladding glass soot is deposited on the laminated soot structure. The resultant composite body is consolidated and stretched to form a rod or core structure upon which the final coating of cladding soot is deposited. The resultant composite body is consolidated and drawn into an optical fiber. In a modification of the this method, the mandrel is removed after the planar soot coatings and preliminary coating of cladding soot are deposited thereon. The resultant soot body is consolidated and processed as described previously.

Title: Circuit breaker
Inventor: SUZUKI YUKIO
IPC: H01H83/00
Filed: 1995-01-09
Abstract: PURPOSE: To avoid a sudden unexpected interruption by generating an alarm output when the higher harmonics of an incoming and distributing system exceed a prescribed value. CONSTITUTION: A master current is detected by current transformers 11-15, its secondary output current is rectified by a commutator 15, and an internal circuit power source is generated by a power source circuit 16, while a detected current is transmitted to a MPU 18 through a signal detecting circuit 17. In the MPU 18, the content ratio of n-order higher harmonics is calculated. The calculation data is compared with a value preset by a characteristic setting part 19 in the MPU 18, and when it exceeds the set value, an alarm is displayed, and an alarm output is also generated. At that time, alarm/interruption can be selected by the distortion of the current waveform.

IPC: E02D5/44
Filed: 1985-01-07
Abstract: PURPOSE:To reliably form an enlarged bulb made of soil cement, by a method wherein, after a concrete pile and a rotary excavating device, engaged internally of the pile, are inserted into a support ground, the excavating device is reversed, and an enlarging blade is unfolded to form an enlarged part. CONSTITUTION:As a rotary shaft 9, engaged internally of a concrete pile 8, is rotated forward in a direction P and excavation effected by means of an excavating bit 1, the pile 8 and the rotary shaft 9 are penetrated down to a support ground. When the rotary shaft 9 is reversed in a direction Q, an enlarging blade 27, attached to a collar 10 of the rotary shaft 9, is unfolded in the direction of an outer periphery thanks to resistance of soil, and an enlarged part is formed at the lower part of the pile 8. In which case, cement milk is injected through an injection nozzle to fill the enlarged part with the cement milk. Thereafter, with the rotary shaft 9 rotated forward in the direction P, the 6nlarging blade 27 is folded, and simultaneously engagement of the excavating bit 1 with the rotary shaft 9 is released, resulting in the possibility to recover the rotary shaft 9 to a ground surface.

Title: Air bag operation controller
Inventor: ANDO HISAHIRO
IPC: B60R21/16
Filed: 1995-01-09
Abstract: PURPOSE: To prevent air pressure in a car room from suddenly going up to a higher one at the time when an air bag body has swollen. CONSTITUTION: An inflator 14A of an air bag unit 14 for a driver's seat is connected to a controller 40 as an operation control means, and an inflator 26A of an air bag unit 26 for an occupant's seat and an air pressure sensor 32 both are connected to this controller 40 as well. In the case where the controller 40 is so judged that a climbing speed of car room internal air pressure is more than the car room internal air pressure, each operation timing of both these air bag units 26 and 14 is shifted from that of other air bag units with one another. Accordingly, each swelling completion time of respective air bag bodies is shifted to some extent, and since a rise in the car room internal pressure becomes moderated, such a possibility that the internal air pressure might be suddenly turned up to a higher one at the time of the swell of an air bag body is thus preventable.

Abstract: PROBLEM TO BE SOLVED: To remove burr at stable quality without asking for a person's help by quenching and tempering a worked object of martensite material generating burr, and next jetting powder of abrasive material as fluid so as to spray it upon the worked object. SOLUTION: At first, a worked object 1 is heat-treated at fixed quenching temperature and tempering temperature, so as to raise the hardness of the worked object 1. A plurality of the worked objects are put in a cylindrical cage 10 in a blast device, thereafter the cylindrical cage 10 is rotated by a motor 14, and the worked objects 1 are stirred. Meanwhile, abrasive material 2 and water 12 received in a tank 15 are stirred, and the mixed fluid 19 is circulated in the tank 15 and a casing 11 by a pump 16.
