Title: Lighting system
Inventor: TAKANO YASUHARU
IPC: H01F38/08
Filed: 1994-09-30
Abstract: PURPOSE: To make possible securing safety by avoiding the danger of an electric shock due to leakage-induced energy generated by high-voltage pulses, without taking any special measures against insulation, such as doubly insulating a ballast. CONSTITUTION: A leakage current flowing via a ballast case 7 enclosing a ballast 5 which starts a discharge lamp 3 by generating high-voltage pulses is constantly monitored by a leakage current detecting circuit 13.

Title: Servomotor controller
Inventor: MASAKI YUJI
IPC: H02P29/00
Filed: 1987-09-21
Abstract: PURPOSE:To control the hunting phenomenon at a motor stop point at the time of zero speed command, by reducing the ripple of a speed detection signal by the output of a comparator circuit at the time of zero speed command. CONSTITUTION:A monostable multivibrator circuit 10 inputs a pulse signal g from a pulse generator 9 to output the pulse h of a certain time length. Then, said pulse h is integrated and converted into a speed signal k. A speed error amplifier 6 supplies a motor with the deviation between a speed command e and said speed signal k via a power amplifier circuit 7. On the other hand, a comparator circuit 12 makes an analog switch 11 operate when said speed command is zero, to increase the integral action time of an integration circuit. In this manner, when the motor is turned by an external force or the like at the time of zero speed command, said motor returns to the original condition by a smooth counter torque.

Title: Semiconductor memory
Inventor: SHIBATA TAKASHI
IPC: G11C29/00
Filed: 1989-09-12
Abstract: PURPOSE:To relieve a defective chip by providing an error correcting circuit for a parity bit caused by the defect of a word line or a bit line, etc., in plural memory mats. CONSTITUTION:Parity bits P0-P2 set the respective outputs of three exclusive logic circuits 55-57 in an error detection circuit 52 at a low level in respect to regular data bits D0-D3 of the memory mat. When there is no error in the bits D0-D3, the outputs of AND circuits 60-63 in an error bit indicating circuit 53 are wholly set at the low level and exclusive logic circuits 64-67 of an error correcting circuit 54 execute outputs while maintaining the level as it is. When the bit D1 is changed to a high level, the outputs of the circuits 56 and 57 are set at the high level and only the output of the circuit 61 is inverted to the high level. Since the high level is applied to one input of the circuit 65 to received the output of the circuit 61, the erroneous bit D1 is inverted by the circuit 65 and outputted as the data D1 at the correct low level.

Title: Filament heating circuit for x-ray tube
Inventor: ISHIYAMA FUMIO
IPC: H05G1/34
Filed: 1987-09-24
Abstract: PURPOSE:To reduce the aging change of the tube current by feeding back the electric power to a filament. CONSTITUTION:The tube current of an X-ray tube 5 is adjusted by adjusting the heating quantity of a filament 9 to control the quantity of the thermoelectrons emitted from the filament 9. If the tube voltage of the X-ray tube 5 is constant, the quantity of the thermoelectrons emitted from the filament 9 is a function of the surface temperature of the filament 9, and this surface temperature is a function of the electric power heating the filament 9. When the feedback control is performed to invariably feed the constant electric power to the filament 9, the surface temperature of the filament 9 is kept constant, and the quantity of the thermoelectrons emitted from the filament 9 is constant. The aging change of the tube current can be thereby reduced.

Title: Superconducting magnet
Inventor: ISHIKAWA HIKONARI
IPC: A61B10/00
Filed: 1984-11-12
Abstract: PURPOSE:To enable the generation of a stable and uniform magnetic field, by incorporating magnetic flux holding coils serially in conventional superconductive compensation windings. CONSTITUTION:Magnetic flux holding coils 11 and 12 are provided at the opposite ends of a hollow cylinder of a superconducting main magnet. By this constitution, the ratio of the number of magnetic fluxes traversing superconducting compensation windings out of the magnetic fluxes generated in a constantly- conducting compensation winding 3 to the total sum of the magnetic fluxes traversing the superconducting compensation windings can be lessened sharply. The reason is that the total number of the magnetic fluxes traversing the superconducting compensation windings 2 and 2' is lessened sharply since the magnetic fluxes generated in the constantly-conducting compensation winding 3 scarcely traverse the magnetic flux holding coils 11 and 12. Accordingly, the rate of a change in the number of magnetic fluxes traversing the superconducting compensation windings 2 and 2', which is caused by a change in a current of the constantly-conducting compensation winding 3, is diminished in a large degree, and consequently a change in a current flowing through the superconducting compensation windings 2 and 2' is reduced.
