Title: Tension adjuster for endless member
Inventor: KONDO TAKESHI
IPC: B65G23/44
Filed: 1994-05-09
Abstract: PURPOSE:To detect the looseness of a belt by a detecting means so that the tension of the belt may be adjusted properly and also adjusted always to a constant value with simplicity. CONSTITUTION:When a dock 63 integral with a bearing 41 serving as a support means moves to turn on a limit switch 60 serving as a detecting means, the extension of a flat belt is informed. Since a nut 48 engaging with an adjusting bolt 42 abuts against a spring bearer 46, the dock 63 cannot move further forward, so that the limit switch 60 or the like may not be broken. When the mounting position of the limit switch 60 is changed and the position of the nut 48 in the adjusting bolt 42 is readjusted, the tension of a spring 47 serving as a resilient means can be adjusted to a substantially constant value by an adjusting nut 43.

Abstract: PURPOSE: To provide an optical transmission system which can transmit the binary digital NRZ fast signals of 10Gb/s or more in a long distance via an optical fiber of large waveform dispersion and also can suppress increase of the cost and the power penalty by reducing the compensation value needed for dispersion. CONSTITUTION: An optical transmission system consists of an optical transmitter 100 which applies a binary digital NRZ electric signal to an optical modulator 4 to modulate the light intensity and transmits a light signal, an optical fiber 101 which transmits the light signal outputted from the transmitter 100 with waveform dispersion, and an optical receiver 102 which receives and turns the optical signal transmitted via the fiber 101 into the original electric signal. Then the modulator 4 is driven after the driving waveform is deformed so as to delay the timing when the output of the modulator 4 is changed to a low level from a high level compared with the timing when the output of the modulator 4 is changed to a high level from a low level by 15% or more of a single time slot.

Title: Erroneous function preventive circuit for reverse power relay at transition of load
Inventor: MATSUMOTO TOKUHIDE
IPC: H02J3/38
Filed: 1994-05-31
Abstract: PURPOSE:To prevent erroneous function of a reverse power relay at the time of transition of a load by resetting a generator, entering into a reverse power region, quickly to the plus side region. CONSTITUTION:Powers from generators AG1, AG2 operating in parallel are detected by means of transducers W1, W2 and the difference required for recovering the reduced power of a generator is operated by means of a sequencer 4 in order to control thy governor for a prime mover 1 or 2. In such control circuit, the transducers W1, W2 can detect power in the minus side (reverse power) region as well as in the conventional plus side region and the sequencer 4 operates the difference using the power in the plus or minus side region. When the power of generator decreases to enter into the minus side region, the sequencer detects the difference using power in the minus side region. Consequently, the difference is increased as compared with a conventional case and the generator output is increased quickly to the plus side. This constitution prevents erroneous function of a reverse power relay 67G1 or 67G2.

Title: Electric precipitation element
Inventor: IGUCHI KATSUMI
IPC: A61L9/20
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce a washing cost in an electric precipitation element. SOLUTION: An electric precipitation element 5 has a dust collection part 30 wherein a dust collection electric board 31 and a voltage application electrode board 32 which are composed of a thin board are alternately laminated. A photocatalyst having an ultrahydrophylic property is applied to a surface of the electrode board 31. The photocatalyst having the ultra-hydrophilic property contains titanium oxide having a rutile type crystal structure. Since a surface of the electrode board 31 is made in a state in which a thin water film spreads, and a stain is stuck onto the water film, the stain can be prevented from being stuck onto the surface of the electric board 31. If only a stain is stuck onto the water film, the stain can be easily washed and flowed off by water washing or the like without using an alkaline washing liquid used conventionally.  Further, since a dewdrop is difficult to be generated on a surface of the electrode board 31, the electrode board can be dried in a short time after washing.

Title: Breathing apparatus of diaphragm-system conservator
Inventor: NAKAJIMA MASASHI
IPC: H01F27/14
Filed: 1990-05-08
Abstract: PURPOSE:To eliminate a need for a humidity-absorbing breathing device and to reduce a maintenance operation by a method wherein a hermetically sealed variable volume expansion chamber in the inside of a housing case used also as a spouted-oil housing tank is connected to the upper-part space inside a tank of a diaphragm-system conservator and to a pressure discharge device and a purge valve which is opened at the same pressure as the operating pressure of the pressure discharge device is attached to the expansion chamber. CONSTITUTION:At a normal operation, a pressure discharge device 8 and a purge valve 14 are in a closed state and an expansion chamber A is connected to only a conservator 2 via a coupling tube 6. As an insulating oil is expanded and contracted, the volume at the upper-part space of a tank of the conservator 2 is increased and decreased. In accordance with this operation, a bag 12 of a breathing device 10 is expanded and contracted as shown by arrows (x), and the inner volume of the expansion chamber A is increased and decreased. As a result, a pressure change portion is absorbed, and an internal pressure is kept nearly at an atmospheric pressure. On the other hand, when the internal pressure of a tank of a transformer 1 is increased and the pressure discharge device 8 is operated at an accident, the pressure inside the expansion chamber A is increased suddenly ad the purge valve 14 is opened. As a result, the air inside the expansion chamber A is discharged and an insulating oil which has been spouted is housed quickly inside the expansion chamber A.
