Title: Portable engine generator
Inventor: NAKAMURA MASAFUMI
IPC: F02B63/04
Filed: 1989-09-05
Abstract: PURPOSE:To prevent the damage of instruments by a method wherein the supply of current from a power source circuit to an output terminal is intercepted when the output side voltage of a field effect transistor becomes lower than the input side voltage of the same by a predetermined value or more and the intercepted condition is continued until reset operation is effected. CONSTITUTION:The input side voltage of a field effect transistor FET is compared with the output side voltage of the same at all times by comparators 6-9. When the output side voltage of the same is reduced lower than the input side voltage of the same by a value larger than a predetermined value, the field effect transistor FET is turned OFF to a intercept the supply of current from a power source circuit 4 to an output terminal 4a and the intercepted condition is continued until reset operation is effected. Accordingly, the reset operation to stop once the generating output of a generator becomes necessary since the output is not reset even if the load is released when the generator is operating continuously whereby the generation of overload current may be surely notified to the operator. According to this method, breakdown of the generator may be prevented.

IPC: G02B6/00
Filed: 1983-12-06
Abstract: PURPOSE:To equalize a voltage share of each part of a light guide, and to prevent a drop of a creeping flashover voltage by winding a semiconductive member having an insulation resistance which is lower than the light guide, to the outside circumference of the light guide. CONSTITUTION:A semiconductive tape being a semiconductive member 5 whose insulation resistance is lower by 1-3 digits or so than a light guide 1 is wound spirally to the outside circumference of a lot of light guides 1, and connected electrically to supporting metallic fittings 2, 3.

Title: Scramble sound transmission equipment
Inventor: ISHIKAWA TOSHIRO
IPC: H04K1/00
Filed: 1986-09-30
Abstract: PURPOSE:To prevent breakage of a speaker at the reception side by stopping the scramble and transmitting the PCM data containing the amplitude data larger than the prescribed value among those PCM data on the sound signals undergone A/D conversion. CONSTITUTION:A transmitter 12 turns sound signals into the PCM data through A/D conversion 14. The PCM data is compressed by a PCM data compressor 15 with more intensive force as the number of bits increase to secure the even number of bits. At the same time, the amplitude of the PCM data is extracted 16 and supplied to a scramble circuit 17. The scramble is released with the PCM data higher than a prescribed level and only the PCM data less than the prescribed level are scrambled 17 for transmission. A receiver 13 applies no descramble 21 to the signal of an amplitude data extractor 16 as long as this signal has a high level and transmits it as it is. While the descramble 21 is applied to the signal of the extractor 16 when the level of this signal is low. Then data undergo expansion 22 and D/A conversion 23 and an analog signal is outputted. Thus it is possible to keep secrecy of the sound signal and to prevent breakage of the speaker of a noncontractor.
