Title: Breakwater
Inventor: ISOZAKI SOICHIRO
IPC: E02B3/06
Filed: 1986-02-28
Abstract: PURPOSE:To keep tidal waves still in the harbor by reducing the reflection of waves by a method in which floats are set at a given interval in the incoming direction of waves in front of a fixed wall and pivotally connected in a vertically turnable manner. CONSTITUTION:In front of a fixed wall 2, floats 5 are set at a given interval A from the wall 2 and in almost parallel with the wall 2 in the incoming direction of waves 3. The floats 5 vertically move according to the heights of the incoming waves 3, where a phase difference results in the rocking movement of the floats 5 by vertical movement of connectors 6 and the floats 5 around the axes 7 and 8 of both ends of the connector 6. Also, the water surface 4 becomes still by the mutual interference of waves resulting from the rocking movement and incoming waves 3. The reflection of waves against both incoming waves of short period and long period can thus be reduced.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To sufficiently display the effect of an error diffusion circuit, to improve the error rate of a receiver and to improve a reception sensitivity characteristic by correcting an error owing to noise superposed on a reception signal between plural symbols. SOLUTION: Instantaneous phase detection circuits 5-8 detect the instantaneous phases for respective reception systems 1-4. Arithmetic circuits 9-12 using a delay circuit operate a phase change amount in one symbol period and the output is supplied to a synthesis circuit 13. Since noise is superposed on high frequency input signals to the respective reception systems 1-4, the outputs of the arithmetic circuits 9-12 also contain the noise errors. The phase difference operation signals of the phase change amount in one symbol period containing the noise error are synthesized in the synthesis circuit 13. The signals are inputted to the error diffusion circuit 14 between the plural symbols. At least one phase correction is executed and the code error rate is improved.  In the output of the error diffusion circuit 14 between the plural symbols, data is demodulated by a demodulation logic circuit 15 and original modulated data is detected.

Title: Circular ferrite magnet, its production and wet type molding apparatus
Inventor: WATANABE HIRONARI
IPC: H01F41/02
Filed: 1992-01-31
Abstract: PURPOSE:To eliminate cracking and chipping on inner and outer circumferential face end sections of a radially anisotropic circular ferrite magnet by adopting a wet type molding method suitable for mass-production. CONSTITUTION:Material powder slurry is filled into a circular cavity which consists of an upper punch 13 with recessed surface, a die 11 and a lower punch 14 with protruding surface, and is compression-molded. When it is assumed that the angle formed by both ends of the inner circumferential face is thetaa, the angle thetaa is 150 deg.<=thetaa<=180 deg., and there exists an outer plane area almost parallel to heightwise direction around both end sections of the outer circumferential face, thereby preventing the increase in molding pressure on the outer circumferential face end section. In the case where the height of the area is ha, and the radial thickness at circumferential direction center t respectively, the following formulae are obtained: (-0.5X10<-2>)thetaa+0.95<=ha; ta<=(-10<-2>)thetaa+2.5. Therefore the inner circumferential face end section can be applied with sufficient pressure. In addition, the difference of compression ratio between around the circumferential direction center and the inner circumferential face end section will become larger if ta is small or thetaa is large, resulting in eliminating cracking and chipping by adopting a appropriate values of ha ta.

Title: Manufacture of ring-shaped magnetic mold
Inventor: TAKAHASHI TSUNETERU
IPC: H01F41/02
Filed: 1984-03-06
Abstract: PURPOSE:To array magnetic powder so that the polarity is reverse between the adjacent zones by radially dividing a ring into four or more even number of zones, radially arraying the powder in the respective zones, and generating a magnetic field at the magnetic members corresponding to the zones. CONSTITUTION:Magnetic members 3 and 5 are alternately annularly disposed around a cavity 7, and nonmagnetic members 1 are interposed between the both members. A composition for a magnet is filled in the cavity 7 to displace magnetic powder. Then, when reverse currents are flowed in the right and left solenoid coils 2, 2, a magnetic field is generated at the magnetic member 3 contacted with the pole piece 1 from the piece 1 or in its reverse direction. The specific magnetic permeabilities of the members 3, 5 as well as an inner mold 4 and the composition for the magnet are largely different, and the members 3, 5 are magnetically shielded by the members 6. Accordingly, a magnetic flux is flowed in the forward or reverse direction, and the powder is oriented in this direction. Since no limit exists in the depth of the cavity due to the magnetic characteristic, a long ring-shaped magnet can be obtained.

Abstract: PURPOSE:To control the forward light of a laser diode to read / write information with a simple optical system by arranging an optical detector on an optical path where the emission light of the laser diode is reflected with a beam splitter. CONSTITUTION:An optical detector 14 is arranged on the optical path of the parallel light from a beam splitter 3. The emission light of a laser diode 1 is shaped to the parallel light with a collimator lens 2, transmitted through the beam splitter 3 and guided to a reflection mirror 4. Then, a part of the light is reflected by the beam splitter 3 and arrives at the light receiving surface of the optical detector 14. Accordingly, negative feedback is loaded to the laser diode 1 with the optical detector 4. For example, when the forward level of the laser diode 1 is increased, the output current of an inversion amplifier 15 is lowered and a bias current to the laser diode 1 is lowered. Thus, the level of the forward light from the laser diode 1 is controlled so as to be fixed.
