Filed: 1989-12-21
Abstract: PURPOSE:To make a contact state constant by providing a gimbals spring having plural rings, and overlapping and bonding a guard with a large diameter projecting from the outer circumferential face of a head slider onto its center ring, thereby reinforcing the center ring. CONSTITUTION:A guard 1a with a large diameter projecting from the outer circumferential face of a head slider 1 is overlapped and bonded onto its center ring 2a of a gimbals spring 2. The top slide face of the slider 1 is brought into contact with a flexible disk and pressed onto the flexible just above with the spring 2. In such a state, the information signal of the flexible disk is able to be recorded/reproduced by the slider 1. Since the guard 1a of the slider 1 is overlapped and bonded onto the ring 2a of the spring 2, the stiffness is large and even when minute vibration caused on the flexible disk is delivered to the ring 2a via the slider 1, the center ring is not resonated. Thus, the information signal is accurately recorded and reproduced.

Title: Synchronizing signal separator
Inventor: MARUOKA TSUYOSHI
IPC: H04N5/08
Filed: 1987-12-28
Abstract: PURPOSE:To avoid malfunction even if a synchronizing signal portion of a luminance signal is shrinked by comparing a 2nd luminance signal outputted from a low pass filter cutting off the high frequency component of a 1st luminance signal with a 3rd potential at a comparator and outputting a signal being the result of separating the synchronizing signal of the luminance signal. CONSTITUTION:The luminance signal inputted from an input terminal 1 is fed to an inverse amplifier 3. A peak detection circuit 4 detects the potential or the tip of a synchronizing signal being a peak potential or the signal to be inputted. A detection circuit 5 detects the potential of the pedestal portion of the inputted signal. A low pass filter 6 eliminates the high frequency component such as noise from the input signal and gives the result to a comparator 8. The comparator 8 compares the output signal of the low pass filter 6 with the potential at the tip of the synchronizing signal of the luminance signal and the potential of the pedestal portion and outputs a signal being the result or separating the synchronizing signal of the luminance signal to the output terminal 9. Thus, even if the synchronizing signal portion of the input luminance signal is shrinked, a correct synchronizing signal separation output is obtained and the time delay of the output synchronizing signal is decreased.
