Title: Gate turn-off thyristor
Inventor: TAKIGAMI KATSUHIKO
IPC: H01L29/423
Filed: 1982-02-02
Abstract: PURPOSE:To prevent flow of zener current after turn-OFF and generation of Joule heat by dividing gate electrode of gate turn-OFF thyristor into several segments. CONSTITUTION:When a turn-OFF pulses are applied respectively to the gate electrodes 17a-17d of a gate turn-off thyristor GTO simultaneously from one or independent pulsers, a GTO becomes ON. Moreover, when gate off pulses are applied to all gate electrodes 17a-17d simultaneously from four pulsers, a GTO turns OFF because a current is absorbed for each electrode. At this time, a large rising coefficient of OFF-gate current can be prepared for each gate electrode. Therefore, a turn-OFF time can be shortened and generation of heat of GTO by Joulse heat can also be suppressed.

Title: Combustion device
Inventor: MIYAUCHI SHINJI
IPC: F23N3/02
Filed: 1990-01-25
Abstract: PURPOSE:To prevent intrusion of rain and reduce noise of combustion exhaust gas by a method wherein an open/close driving signal for making the opening rate variable is outputted to a means for driving a discharge opening rate variable part based on a rain-fall signal from a rain sensor for use in detecting a rain-fall. CONSTITUTION:During a rain-fall, some rain droplets adhere to a rain sensor 9, an electrical energized state occurs between some electrodes and this state is outputted to a discharge opening rate control means 14 as a rain-fall signal. The discharge opening rate control means 14 outputs an energization signal to a solenoid 13 and supplies a coil current. The solenoid 13 generates an electromagnetic force to the other end (a movable iron core) of a metallic lifter 12 with a coil current so as to retract the metallic lifter 12. Accordingly, the discharge opening rate variable part 10 is moved toward a position denoted by 10' against the biasing force of a leaf spring 15. With such an arrangement, the opening rate is reduced and maintained at a predetermined opening rate and then intrusion of rain into a discharging part 3 is prevented. At this time, although a gas discharging resistance at the gas discharging part is temporarily increased, a combustion discharging gas sound caused by the discharging gas resistance is not noticed as the noise sound. When no rain falls, since the discharging gas resistance at the gas discharging part is substantially decreased, the combustion discharging gas noise is remarkably reduced.

CONSTITUTION:The presence / absence of the connecting relation in the manner of semantics between the appearance of the verification object word and the semantic category equipped with case elements to be shown by a verification object case determination dictionary 7 out of the clause to modefy the objective word of verification is calculated while retrieving a semantic connection dictionary 8, to which these connection possibility information are described in advance, with the appearance of the verification object word and when there is no connecting relation in the manner of semantics, the objective word of verification is detected as homonym error. In respect to the detected homonym error, a word equipped with the same reading is extracted as a correction candidate and this correction candidate is replaced with the word which is verified as the homonym error. Then, verification is executed by using the semantic connection relation and the connectable correction candidate is defined as a correct candidate to the homonym error. Thus, only the correct candidate of the homonym error can be extracted.
