Title: Active filter for power distribution
Inventor: TSUNEHIRO YUZURU
IPC: H02J3/18
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To downsize a converter which supplies the compensating current of fault currents superposed on a distribution line, and reduce the cost. SOLUTION: A compensating current detector 4 receives the input of load currents iLu, iLv, and iLw flowing to each phase of a distribution line 1 by a current transformer CT, and detects the fault current (reverse current + higher harmonic current) ik (k=u, v, w) of each phase from the load current. A current control converter 5 generates compensating currents iCu, iCv, and iCw, based on the fault current ik (becomes a command value Kik, being increased k (k>1) times with a detector 4). The primary winding of each phase of a three-phase transformer 6 is supplied with compensating currents iCu, iCv, and iCw outputted from the current control converter 5. One end of the secondary winding of each phase of the three-phase transformer 6 is connected to a three-phase cage rotor induction motor 7, and the other end is connected to each phase of a distribution line.  The three-phase cage rotor induction motor 7 rotates with no load, and takes partial charge of positive-phase voltage.

Title: Sealing material for oily fluid
Inventor: TERAWAKI SEIKICHI
IPC: F16J15/14
Filed: 1988-08-11
Abstract: PURPOSE:To obtain a sealing material which can give a seal of a high capability of sealing and a high shape retentivity, by incorporating a specified swellable particles in the voids of a matrix formed by binding fibers with an oil-resistant binder. CONSTITUTION:A sealing material is formed by incorporating swellable particles formed by coating an inorganic filler with an oil-swellable substance in the voids of a matrix formed by binding fibers with an oil-resistant binder. Although the fiber used is required to be an oil-resistant fiber, it is usually necessary that is has heat resistance; therefore inorganic fibers such as glass fiber, ceramic fiber, or rock wool fiber are desirable. As said oil-resistant binder, one having rubber elasticity is desirable. Especially when a nitrile rubber, a fluororubber or the like is used, it can exhibit resistance to various oils, as oily fluids, ranging from a hydrocarbon to a fatty oil.

Title: Track signal detecting device
Inventor: TAKAHASHI TOSHIAKI
IPC: B61L1/18
Filed: 1993-07-22
Abstract: PURPOSE:To obtain a compact size and easy adjustment and also detect three different-phase, i.e., similar, opposite and none phase signals by installing local inputting circuit, track inputting circuit and processing circuit, having the respective specific functions, and electronizing functions of a track relay. CONSTITUTION:A local inputting circuit 1 generates a reference signal S4 when a local signal S3 of similar or opposite phase in respect to a transmitting signal S1 changes in between positive and negative. A track inputting circuit 2 A/D converts a track signal S5 and outputs it as a track output signal S6. A processing circuit 3 stores a phase difference from the time when the reference signal S4 is inputted to the time when the track output signal S6 reaches to crest value as a reference phase difference. And further, the circuit 3 multiplies the crest value by a cosine value between a phase difference based on a reference output signal S6 and a phase difference. And thus, detection signals are outputted, as follows; a similar phase signal when the multiplied value is above a positive reference value, an opposite phase signal when it is below a negative reference value and a none phase signal in other cases.

Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To improve the electrode quality and secure a welding strength with the usage of the electrodes by dressing the electrodes in a way that a pressurization power of the electrode having a larger dressing area is set stronger against that of the one having a smaller dressing area, thereby the both electrodes can be dressed uniformly. SOLUTION: When the upper electrode 10, having a larger dressing area, and the bottom electrode 12, having a smaller dressing area are dressed opposing each other, they are dressed having the pressurization power of the electrode 10 set at stronger than that of the electrode 12. Thereby, a pressing power per unit area against each electrode 10, 12 become even and the both electrodes 10, 12 are made to dress evenly.

When the welding is conducted with the electrodes 10, 12, generation of spatters are reduced and the welding strengthness can be obtained. Furthermore, the pressurization power against the electrodes can easily be changed as a dress unit 19 is elastically held in the direction of the pressurization and changes the power is changed at the position when the dressing is started.

Title: Semiconductor optical wavelength filter
Inventor: WAKATSUKI ATSUSHI
IPC: G02B6/12
Filed: 1989-08-04
Abstract: PURPOSE:To obtain the steep wavelength selectivity and sufficient wavelength blocking characteristics of the directional coupler type optical electrode filter and to facilitate the production thereof by forming the filter in such a manner that at least one of the waveguides has a shutting off area in a zero order waveguide mode. CONSTITUTION:The W type waveguide 2 which is the 1st waveguide has the shutting off area in the zero order waveguide mode and, therefore, the equiv. refractive index of the zero order mode decreases considerably with an increase in the wavelength. The dispersion curve of the W type waveguide, therefore, intersects steeply with the dispersion curve of the step type waveguide which is the 2nd waveguide having a less change in the equiv. refractive index. The filter has the sufficient wavelength selectability accordingly. The control of the refractive index of the cores, clads, etc., of the respective waveguides is facilitated simply by successively laminating the respective layers 2, 3 of the waveguides with this SW type filter. The steep wavelength selection characteristics and the wide blocking area are obtd. in this way and the production is facilitated.
