Next, a pressing metal fitting against side pressure is installed on the form 14 to prevent the form member 14 from slipping longitudinally. A floating up preventing metal fitting is then attached to the form 14 to prevent the form member 14 from floating upward. Next concrete is cast through a hole formed on the upper face of the form member 14. After the curing of concrete, the pressing metal fitting against side pressure and the floating up preventing metal fitting are removed. The form member 14 is made to survive for protecting the high balustrade and preventing the occurrence of crack in the concrete.

Title: Frequency demodulation circuit and optical disk device having the same
Inventor: HIDA MINORU
IPC: G11B7/00
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To execute the demodulation processing of a frequency modulation signal a with simple constitution and to exactly demodulate digital data even if there is a deformation by a defect, etc., of a recording medium in the frequency modulation signal. SOLUTION: The address information ADM after bi-phase modulation is subjected to frequency modulation and is recorded as a groove wobble. A wobble signal SWB which is a reproducing signal of this groove wobble is modulated to a binary signal PWB. The wobble signal SWB has 4 waves at the time of a '1' and 3 waves at the time of a '0' in correspondence to the 1 bit (bi-phase 1 bit) of address information ADM. Demodulation processing is executed in a detecting circuit 67 by using a clock signal CK24 synchronized with the pulse signal PWB having a frequency of 24 times the bit frequency of the bi-phase. In this processing, the '1' and '0' are decided by utilizing the coincident number of the edge detection signal of the binary signal PWB and the window pulses relating to the patterns of the binary signals respectively corresponding to '1' and '0' of the digital data.
