Title: Composite magnetic head
Inventor: HAYAKAWA ATSUNORI
IPC: G11B5/127
Filed: 1983-04-29
Abstract: PURPOSE:To reduce the crosstalk of magnetic flux between a reproduction and a tunnel erasure side by combining a magnetic head part for recording and reproducing and an erasing head part with each other, and bringing the erasing head part into contact with a magnetic recording medium at its gap for erasure. CONSTITUTION:The erasing head part 12 consists of a ring head part 12a and a nonmagnetic material part 12b. The head part 12a forms a magnetic path by magnetic cores 13 and 14 and is provided with head gaps 15a and 15b for tunnel erasure. Then, U-shaped grooves 26 and 27 are formed in the block of the erasing head part 12 in order to provide tracks to two ferrite blocks 24 and 25. Those ferrite blocks 24 and 25 are connected by fusion with glass 25a to, for example, an about 0.3-1mum gap length, and a nonmagnetic block 30 having a winding groove 29 is joined thereto in specific position relation. Thus, leak magnetic flux on the tunnel erasure side is reduced, so the crosstalk of magnetic flux is reduced.

Abstract: PURPOSE:To attain efficient level adjustment at the reception side by extracting a signal of a prescribed frequency from a received signal and detecting a detection signal when an output signal level is a prescribed level or over so as to apply the control bringing the output signal to a prescribed level. CONSTITUTION:In receiving a test signal, a reception section 61 of a transmission/reception station 121 extracts only the test signal of a prescribed frequency from the received signal, the signal is rectified into a DC and retards it for a prescribed time and supplies the result to a noninverting input of a comparator 5. When the voltage of the signal after the delay is larger than the voltage applied to the inverting input by means of resistance division, the comparator outputs a detection signal, resulting that an output signal of a reception circuit 4 is supplied to a level monitor circuit 12. In such a case, the level monitor circuit 12 monitors the output signal of the reception circuit 4 to control the attenuation of a variable attenuation circuit 3. Thus, the level of the reception signal is made constant and the level adjustment at the reception section is executed efficiently.

Title: Parapet construction
Inventor: HAYAKAWA TOSHIYUKI
IPC: E04D13/14
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a parapet construction capable of definitely preventing the occurrence of snow eaves and of reducing construction cost without degrading the design of appearance. SOLUTION: A parapet 20 has an obtuse angle at a corner 24 where a rooftop slab 6 faces and intersects with a parapet inner wall 22 and, from this corner 24, an ascending sloped surface continuing to the crown is formed on which a coping metal 8 is fixed. If wind blows to the parapet 20 in a direction shown by broken lines and arrows, then the wind and snow hitting the parapet inner wall 22 as an ascending sloped surface does not lose the velocity at the hit point and instead smoothly flows upward along the parapet inner wall 22 and further flows from the coping metal 8 to the outside of the roof top. In this way, wind flows smoothly without stagnation along the side of parapet inner wall 22 so that the occurrence of snow eaves at a lower portion of the parapet inner wall 22 can be prevented in most cases. Therefore, the problem of water leakage to the inside of the building can be also eliminated.
