Title: Core for magnetic head
Inventor: SUMITANI SHINJI
IPC: G11B5/127
Filed: 1989-06-08
Abstract: PURPOSE:To allow the adjustment of the impedance at the time of assembly of the cores having tapered parts and to eliminate the fluctuation in the impedance by elastically mounting a leaf spring between the outer side surfaces of both tapered parts of two pieces of the cores and adjusting the pressing force of the contact part. CONSTITUTION:The magnetic head body 11 is constituted by pressing the end faces 5A, at one end, of two pieces of the cores 5 via a gap spacer 2, elastically mounting the leaf spring 6 between the outer side faces of the tapered parts 5C and mounting the coil 3 to the other end part. The impedance of the core 5 for the magnetic head is measured in such assembled state. The spring 6 is moved in the direction parallel with the end face 5A to adjust the pressing force of the contact surface 5A and to regulate the impedance when this impedance does not come within a prescribed range. The impedance is thereby kept within the determined range. The fluctuation in the finishing impedance and electrical characteristics of the magnetic head is confined within a specified range in this way.

IPC: H03J7/02
Filed: 1977-12-06
Abstract: PURPOSE:To increase the speed of the lead-in action for the carrier reproducing circuit in the PSK demodulator circuit as well as to prevent the cycle stop occurrence by providing the high band pass filter inside the AFC loop and the low band pass filter outside the loop respectively. CONSTITUTION:High band pass filter 3a is provided inside the AFC loop of the carrier reproducing circuit, and low band pass filter 3b whose central frequency is identical to that of filter 3a is provided to the front step of frequency converter 7. In such constitution, the AFC loop containing filter 3a controls voltage oscillator 1 via phase detector 5 so that the output frequency of frequency converter 2 may coincide with the central frequency of filter 3a regardless of variation of the input frequency. In other words, the high-speed lead-in operation becomes possible since filter 3a features the high band performance and positions inside the AFC loop. At the same time, the occurrence of the noise and the cycle stop can be suppressed and prevented since low band pass filter 3b is within the loop.

Title: Disk device
Inventor: MIWA HIROSHI
IPC: G11B17/32
Filed: 1990-06-06
Abstract: PURPOSE:To stably maintain contact between a magnetic head and a recording medium by generating an air flow between the medium and a medium sucking device and sucking the medium to stationalize its vibration. CONSTITUTION:When a disk motor 24 is rotated, a flexible disk (FD) 20 directly connected to the motor 24 is rotated in the clockwise direction and its peripheral air flows in the circumferential direction of the FD 20 due to its viscosity. At this time, a part of air flowing along the FD 20 is interrupted by the edges of the medium sucking device 33 arranged in the vicinity of the FD 20 and the sectional area of a passage is increased by the taper faces 34, 35 formed on both the sides of the device 33, so that air density is reduced. Thereby, the FD 20 is attracted to the device 33 side and can be contacted with the exposed magnetic gap of the magnetic head, or allowed to be close to the gap by the submicron order. Consequently, relative positional accuracy between the flexible recording medium and the medium sucking device is highly accurately maintained at the time of rotating the recording medium.

Title: Device for compensating solid-state image pickup element defect
Inventor: SAKATA HARUO
IPC: H04N5/378
Filed: 1987-06-11
Abstract: PURPOSE:To use an inexpensive solid-state image pickup element by discriminating whether the defect length is one picture element or two picture elements, and executing a linear interpolation from the previous and following signals in accordance with said result, so that a fault on the picture plane is scarcely observed visually. CONSTITUTION:An image pickup element 1 outputs a video signal by a clock period tau. White and black are detected by amplitude detectors 2, 3, and a defect level is detected by reference levels E1, 4, E2, 5, respectively. Signal forming circuits 6, 7 and a polarity inverting circuit 8 set a defect signal part as a positive polarity pulse of tau or 2tau, and both of them are added by a synthesizer 9. On the other hand, an output of the element 1 is led to delay elements 24, 11-14 of tau unit. The element 24 compensates a delay of a control signal which follows up a discriminatin of a judging circuit 10, and when there is no defect, an output of the element 12 is connected to a point (a) of a switch 23. At the time of the tau defect, the element 11 and 12 are added by an adder 15, reduced to 1/2 by an attenuator 16 and connected to a point (b). At the time of the 2tau defect, a compensating output is obtained to a point (c) from outputs of the elements 24, 12, and a compensating output is obtained to a point (d) from outputs of the elements 11, 14. The switch 23 is controlled by an output of the circuit 10, and becomes an output 25.
