Title: Thyristor bulb
Inventor: TADA KAZUHIKO
IPC: H02M1/088
Filed: 1984-07-25
Abstract: PURPOSE:To obtain an inexpensive thyristor bulb which has a simple structure by detecting a current as a thyristor, and firing the all thyristors when the current exceeds the specified value, thereby reducing the necessary number of current detectors and weight guides. CONSTITUTION:A fire command signal 10 which represents a normal conduction command period is input from the exterior to a fire controller 9, a fire signal of narrow width pulse is fed through a fire signal transmission system 11 to the respective thyristors 1 to turn ON the thyristor bulbs. The signal 10 is also applied through a NOT circuit 24 to an AND circuit 23 to supply the AND output of the output of an overvoltage detector 16 to the controller 9. When the commutation current of the bulb increases to exceed the prescribed value, a light emitting diode 22 emits a light. The light output is input through a light guide 15 to the detector 16. As a result, the output of the detector 16 becomes positive level, and a fire signal is fed to the respective thyristors by the operation of the controller 9 to fire the thyristors which are turned OFF.

Abstract: PROBLEM TO BE SOLVED: To decrease partly increasing earthquake-response values in a layer without oil dampers, by installing oil-dampers in the structural face of every other layer or through multi-layer of a building. SOLUTION: A long hole in which a dowel pin fixed to a brace 3 side is inserted, is bored, in the crossing of braces 3 of every other layer of a building constructed to form a X-shape. The braces 3 are horizontally connected with an oil damper 4 through a bracket so as to hold an auxiliary damper with the brace 3 side along both sides of the long hole. In this time, the braces 3 are assembled to form a V-shape at the upper layer and an inverted V-shape at the lower layer, at the structural face of a column 1 and a beam 2 and both brace heads are connected to each other through the bracket and the damper 4. The dowel pin prevents the deformation at the outside of the structural face of the brace 3 in the long hole and at the same time, the auxiliary dampers arranged at both sides of the dowel pin can bring out the correspondent attenuating effect.

Abstract: PROBLEM TO BE SOLVED: To obtain accurate positioning in the entire region from a low speed region to a high speed region by controlling in combination of a closed loop control utilizing the counterelectromotive force of a stepping motor and open loop control utilizing no counterelectromotive force of the motor. SOLUTION: The current value and voltage value of a pulse current generated by a driver 20 are fed back to a controller 10 by counterelectromotive force calculating means 11 of the controller 10, and the counterelectromotive force is calculated based on the current and voltage values. The position of a rotor is calculated by using the counterelectromotive force by rotor position calculating means 12, the position of the rotor is compared with an command position. If there is a deviation, the drive pulse is corrected by the correction pulse. When the counterelectromotive force is not generated, the position of the rotor is controlled without using the means 11 and 12. Thus, the positioning can be accurately conducted in the entire region from the low speed region to the high speed region.

Filed: 1981-10-06
Abstract: PURPOSE:To perform monolithic IC-implementation and to vary gain settings, by using an analog switch consisting of a field effect transistor as a switching means, and using a locked resistance network as a feedback resistance circuit. CONSTITUTION:A locked resistance network 13 is inserted between the output terminal of a differential amplifier 11 and a reference terminal 17. An optional connection point in the network 13 is selected previously in accordance with a necessary gain setting program, and then connected to the out-of-phase input terminal of the amplifier 11 through an analog switch network 12 by lines 14a- 14d. A signal V2 is inputted to the in-phase input terminal 15, and the differential input signal of a signal V1 is inputted to the terminal 17. In this case, gain G is (R1+R2)/R1, where R1 is the value of resistance between the terminal 16 of the network 13 and the network 12 and R2 is the value of resistance from the network 12 to the output terminal 16 of the amplifier 11. Therefore, the network 12 is operated by a control signal to change connection points in the network 13, so a feedback resistance value varies accordingly to vary the gain of the amplifier 11.
