IPC: H04L27/20
Filed: 1983-12-15
Abstract: PURPOSE:To enable to obtain a minimum shift keying MSK modulation output with a satisfactory higher-harmonic distortion ratio by using a switched capacitor filter SCF because of waveform molding, and by forming a low-pass filter which is different from the SCF on only one chip for the output. CONSTITUTION:An SCF can constitute a filter which is very accurate and needs no adjustment, and on the other hand, a clock frequency which switches a switch element is a sampling filter which is sampled by several ten times for the applied frequency area. Then, a low-pass filter which is the primary or above is provided on only one chip and formed for the filter output composing an MSK modulation integrated circuit SCF to prevent clock frequency leakage to the filter output. When a control signal is inputted to an MSK control input terminal 5, a stair step wave form is formed by a timing circuit 1 and a D/A conversion circuit 2, higher harmonic components are removed by an SCF3, and the output with a satisfactory higher-harmonic distortion ratio can be obtained as an MSK modulation output by removing the clock frequency by an LPF4 of the next step.

Title: Magnetic head supporting device
Inventor: KUBO TSUYOSHI
IPC: G11B17/32
Filed: 1986-10-06
Abstract: PURPOSE:To make a floppy disk difficult to be damaged and to prevent a magnetic head to slip off a track as well by providing the spring energizing in the direction that the arm regulating the movement to the inner side of two carriage mounts and a magnetic head are brought into contact with each other. CONSTITUTION:At the time when the flapping of a floppy disk 36 is small, carriage mounts 5 and 6 are displaced by following the floppy disk 36 without abutting to the projections 10a and 10b of an arm 10 respectively. When the floppy disk 36 is displaced more than a certain degree with its flapping, the carriage mount 5 becomes in a stationary state by abutting to the projection 10a. In case of its flapping largely in A direction more than that, it is necessary to press by the force stronger than the elastic force of a sprig 11 in order to displace in A direction a magnetic head 2 and the carriage mount 6, but due to the elastic force of the spring 11 being stronger the flapping of the floppy disk 36 is forcibly restrained. A forcible restraint is capable similarly even in the case of the floppy disk 36 flapping largely in the arrow mark B direction.
