摘要： PURPOSE:To prevent improper insulation of both ends of a laminated core in an inexpensive structure. CONSTITUTION:Before a core 4 is manufactured by lamination, the inner surface of a core end plate 9 arranged on edges 13, 14 of the core 1 in which a plurality of core plates 8 are laminated and end faces 11a, 11b of a tooth 11 are covered with first insulating films 6. After the core 4 is fabricated by lamination, the inner surface of a slot 10 of the entire core 4 and end faces 11a, 11b of the tooth 11 are covered with second insulating films 7. Thus, an insulating layer of the plate 9 becomes about twice as thick as that of the insulating layer of the other core plate 8 to prevent damage of the edges 13, 14 of the core 4 at the time of inserting a coil. The plate 9 is formed of the same magnetic material as that of the plate 8. Thus, the same punching die as that of the plate 8 can be used to obtain the inexpensive core end plate 9.

摘要： PURPOSE:To easily change rated voltage without changing a shape in each part of an armature by providing an idle slot, where no coil is fitted, and paired short-circuited segments, which short-circuit two commutator segments, in an equal quantity. CONSTITUTION:An armature 1 is constituted of slots 110 to 124 of an almost cylindrical iron core 5 fitted to a rotary shaft 3, coils 7a to 7j, commutator 9, etc. The coils 7a to 7j are fitted to the ten slots 110 to 119 of the total 15 slots 110 to 124, and no coil is fitted to the rest of the slots to provide the idle slots 120 to 124. The commutator 9 has 15 commutator segments, and the commutator segment numbers 10 by electrically connecting the fellow segments in every third place. When, the number of the coils is decreased, the rated voltage is decreased, but a current conduction amount is increased by the decrease of the number of the coils to increase torque. An output characteristic is not changed because a rotational speed is not changed.

摘要： PURPOSE:To easily add an automatic discriminating function for discriminating a tape for appreciation from a 'KARAOKE' (recorded instrumental accompaniment) tape and a lyric displaying function to the titled device by receiving a lyric display signal outputted from a detecting means and displaying lyrics. CONSTITUTION:When a magnetic tape R is a 'KARAOKE' tape, the detecting means M2 connected to a speaker connecting terminal T0 of a reproducing means M1 detects that a speaker output signal outputted from an output terminal T0 is a lyric signal and then outputs the 1st detecting signal. The detecting means M2 detects the operating state of the reproducing device M1 and generates the 2nd detecting signal. Receiving the 1st detecting signal, a display means M3 displays lyrics reproduced by the reproducing means M1 on the screen of a display device, and at the reception of the 2nd detecting signal, erases the display of the lyrics from the screen. A switching means M4 can switch performance reproduced by the reproducing means M1 to stereo reproducing or monaural reproducing, and at the input of the 1st detecting signal, switches the stereo reproducing to the monaural reproducing. An amplifying means M5 amplifies an arithmetic signal and outputs the amplified signal to a speaker S.

摘要： PURPOSE: To obtain an EL ageing device with the simple structure, which can accurately detect the fine breakdown and can prevent the chain breakdown due to the fine breakdown. CONSTITUTION: The current flowing to an EL element 1 is detected by a current detecting resistor 10. A personal computer 5 compares the waveform of this detected current with the previously stored waveform of the normal current, and judges whether the fine breakdown is generated or not. In the case where the generation of fine breakdown is judged, application of voltage to the EL element 1 is instantaneously interrupted by direct current power sources 3, 4 through GPIB controllers 6, 7, and thereafter, voltage is gradually reset to the applied voltage just before the interruption.
