Title: Protective method for transformer
Inventor: INAGAKI KEIZO
IPC: H02H7/045
Filed: 1988-04-06
Abstract: PURPOSE:To perform protection of a transformer with high accuracy and high speed, by determining the phase currents of a transformer having delta- connection windings based on the differential currents obtained on the basis of line currents fed from respective terminals of the transformer and the differential currents obtained on the basis of the phase currents, and employing the phase currents for judgement of inner fault of the transformer based on the parallel admittance of the transformer. CONSTITUTION:Differential currents are obtained with respect to line currents i1a, i1b, i1c, i2ac, i2ba, i2cb. Absolute values of these differential currents are compared with a first detection level in order to obtain the phase currents i2a, i2b, i2c of delta-connection windings. Then it is judged whether the absolute values of the differential currents concerning to these phase currents i2a. i2b, i2c are larger than a second detection level or not. Initial setting is made for the first judgement while parallel admittance is operated for second and following judgements, then the operated parallel admittance is compared with a judgement value thus judging an inner fault. If the condition continues, it is judged that an inner fault exist in the transformer and a signal for allowing trip of circuitbreaker is produced.

IPC: F04C15/00
Filed: 1983-05-13
Abstract: PURPOSE:To prevent consumption of unnecessary energy, by changing the effective diameter of a variable pulley through the feed of a pressurized fluid, varying its pressure dependent on the operating condition of an engine, into a hydraulic cylinder. CONSTITUTION:The pressure in a pressure chamber 34 varies with the number NP of revolutions in a range of more than the number NP1 of revolutions, and a pressurized fluid whose pressure is converted into a pressure proportional to the pressure in the pressure chamber 34, is outputted through an output port 45 of a pressure control valve. The pressurized fluid is exerted on a cylinder chamber 21 of a hydraulic cylinder 20 to increase the effective diameter of a variable pulley 16 against the repulsive force of elastic restoring members 18, 4a and 4b and simultaneously decreases the effective diameter of a variable pulley 3, resulting in preventing consumption of unnecessary energy.

Filed: 1990-04-02
Abstract: PURPOSE:To prevent the integral running distance data and a storing address which stores the running distance data from being broken when electricity is supplied by writing and correcting the integral running distance data at a shorter running distance than usual when an error is brought about. CONSTITUTION:A counter 8 counts pulses of a running distance sensor which are output every time a vehicle runs a predetermined distance, with generating a first signal S1 every time the running distance becomes a first predetermined value. Moreover, the counter 8 generates a second signal S2 every time the running distance reaches a second predetermined value shorter than the first predetermined value. When an error checking circuit 7 detects an error, a latch circuit 9 temporarily stores the content, namely, the changing address and correcting data of the integral running distance. Every time the first signal S1 is input, normally, the integral running distance data of a presettable counter 2 is stored in an involatile memory 6. Meanwhile, at the occurrence of an error, the address of the involatile memory 6 is updated in accordance with the content of the latch circuit 9 when the second signal S2 is input, and the correcting data of the integral running distance is written into the updated address.

The width (d) of the vibrator 5 or the mounting width (d) onto the wedge 2 of the vibrator 5 is set so as to satisfy an expression of (d)<0.44λ/sin (5π/180). In the expression, λ represents the wavelength of ultrasonic waves in an object to be inspected.  When the width (d) of the vibrator 5 satisfies this condition, the angle of beam spred of the ultrasonic waves becomes 5 deg. or higher, the ultrasonic waves advance in the object, to be inspected, at a wide spread angle, and a flaw having a large inclination angle can be detected surely. In addition, since the area of the vibrator 5 is large, the energy of the reflected waves is kept to be high, and an S/N ratio is not lowered.

Title: Manufacturing device for extrusion molding
Inventor: SATO SUSUMU
IPC: B29C48/30
Filed: 1990-03-30
Abstract: PURPOSE:To finish beautifully a cut surface of a removal part by making the cutting quality of a blade favorable, by a method wherein a section of the blade of a cutter is formed into a streamline and the blade is constituted so that the blade is capable of making rocking and displacement centering around a shaft meeting at right angles with a forward or backward movement action direction of the cutter. CONSTITUTION:An extrusion-molded product having a fixed sectional form is extrusion- molded by extruding a molding material through a mouth piece of an extrusion head. Then a part of the extrusion-molded product which is directly after molding is removed by causing a cutter 1 arranged on a front side of the mouth piece to perform a forward or backward movement action within a plane which is parallel with the front of the mouth piece. In this instance, a section of the blade 3 of the cutter 1 is formed into a streamline and the blade 3 is constituted so that the blade 3 becomes capable of making rocking and displacement centering around a shaft meeting at right angles with a forward or backward movement action direction of the cutter 1.With this construction, since the blade 3 of the cutter 1 changes autonomously a direction in the direction where resistance is reduced as low as possible by resistance between the blade 3 of the cutter 1 and the extrusion-molded product which is directly after molding, a favorable cut surface is obtained.

SOLUTION: This iridescent reflective sheet has between an absorbing polarizing plate 1 and a reflecting layer 4 a phase difference layer 2 and a polarization scattering layer 3 showing scattering anisotropy depending on the direction of polarization and located on the reflective layer. Reflected light derived from light linearly polarized via the absorbing polarizing plate and impinging on the reflective layer varies a polarized state in the direction of visibility by means of the scattering anisotropy provided by the polarization scattering layer, and, depending on the polarized state, color changes occur in apparent color polarization phenomenon produced by the phase difference layer and the absorbing polarizing plate, so that the iridescent reflective sheet whose color varies depending on visual angle can be obtained.  Coloring can be easily varied by varying phase difference, and iridescent colors having the relationship of complementary colors can also be produced. Reflected light consisting of linearly polarized light can be directly used in a liquid-crystal display.
