Title: Magnetic disk device
Inventor: TAKAHASHI KAZUYOSHI
IPC: G11B33/14
Filed: 1990-02-28
Abstract: PURPOSE:To avoid the degradation of assembling precision of members in a head disk assembly by providing a desiccating agent housing means, where the opening area of an air hole is changed in accordance with the change of the relative humidity of internal air, in a base plate. CONSTITUTION:A humidity detector 57 detects the relative humidity of internal air of a base plate and converts it to an electric signal and outputs the electric signal to a controller 58. When the relative humidity of internal air quickly rises, a disk 56 is rotated to extend the opening area of an air hole 52 and internal air is quickly dehumidified by a desiccating agent 51. When the relative humidity of internal air is reduced too much, the disk 56 is rotated to narrow the opening area of the air hole 52 or completely close the air hole 52 and the reduction of the relative humidity is prevented. Thus, the degradation of the assembling precision of members in the head disk assembly due to the overdrying of the internal air is avoided.

Title: Manufacture of magnetic powder for magnetic recording
Inventor: IDO TADASHI
IPC: G11B5/842
Filed: 1990-02-27
Abstract: PURPOSE:To obtain hexagonal ferrite magnetic powder suitable for perpendicular magnetic recording mediums with a large planarity ratio and a sharp distribution of grain size by making a raw composite contain ZrO2 as the vitrification ingredient to form ZrO2-AO. CONSTITUTION:A raw composite contains ZrO2 to form ZrO2-AO as the vitrification ingredient. ZrO2 hardly dissolves in ferrite ingredient and has a high melting point to suppress the crystal growth of hexagonal ferrite in glass, to sharpen the distribution of grain size of magnetic powder, and to tend toward enlargement of planarity ratio. Therefore, a resulting hexagonal ferrite magnetic powder attains a planarity ratio of 3-10 that sufficiently exhibits the effect of perpendicular magnetic recording with the result that the distribution of grain size is sharpened by a grain size of 0.01mum-0.3mum that allows sufficient recording- reproduction at a recording wavelength of 1mum or less. This process can provide a hexagonal ferrite magnetic powder which sharpens the distribution of grain size and exhibits the effect of vertical magnetic recording more sufficiently.

Filed: 1989-02-28
Abstract: PURPOSE:To improve assembly workability and to secure dimensional accuracy by forming a rotation stopping projection on both or one side of a locking hole, providing an abutting part at the rotation stopping play hole, and fitting the projection. CONSTITUTION:Rotation stopping projections 3b and 3b are formed so as to slightly deviate toward an objective lens side with respect to a locking hole 3a formed position, when a locking pin 22 is fitted into the locking hole 3a, and in a state of the rotation stopping projections 3b and 3b are fitted into rotation stopping play holes 23 and 23, one part of the external peripheral wall of the rotation stopping projection 3b abuts on one part of the internal peripheral wall of the respective rotation stopping play holes 23.

Thus the locking pin 22 can be easily erected and manufactured, and the accuracy can be easily secured.

Filed: 1983-03-24
Abstract: PURPOSE:To facilitate an accurate measurement by arranging a meteorological sensor for generating an electric signal corresponding to the temperature and atmospheric pressure and a meteorological correction circuit for performing a corrective computation based on an output signal of the meteorological sensor. CONSTITUTION:A light emitter 2 generates light modulated in the amplitude with a modulating wave as illustrated (a) generated by an oscillator 1 and projects it as projection light 3. When reaching a target point, the projection light 3 is sent back as reflected light 5 with a reflector 4. A photo detector 6 outputs a signal corresponding to the intensity of the reflected light 5 when the reflected light 5 reaches it 6. But, as the projection light 3 is modulated by a signal as illustrated (a), the photo detector 6 generates and feeds a signal as illustrated (b) to a phase comparatos 7. The phase comparator 7 to which another signal are fed from an oscillator 1, which detects the phase difference between both the signals. In this case, since the signal fed from the photo detector 6 generated after the projection light 3 reciprocated to and from the target point, it is delayed by the time T from the signal generated from the oscillator 1 as illustrated (a).

Title: Start-stop type data multiplexing system
Inventor: YOSHIDA KAORU
IPC: H04L7/04
Filed: 1990-03-02
Abstract: PURPOSE:To remove a data transmission error by converting N data in a unit section into an alternately repeated format of N+1 and N-1 and executing staff processing by the continuous format of N+1 or N-1 in accordance with the variation of input data. CONSTITUTION:A staff control circuit 7 alternately controls N reading clocks C in a unit section line N+1 and N-1 and applies the controlled result to a buffer memory 4. If a phase difference corresponding to one clock is generated when the frequency of a synchronizing clock (b) formed by an asynchronization/ synchronization converting circuit 3 is slightly higher than the frequency of a reading clock (c), the output of a phase comparator 8 is enabled, the circuit 7 continues the N+1 state of the output clocks, and since the phase difference is reduced by the control, the alternate repeat of N+1 and N-1 is continued. Then staff information (f) deciding the number of data, i.e., N+1 or N-1, in the unit section is sent from a timing adjusting circuit 10 to a multiplex control circuit 11. Consequently, the time division multiplex transmission of start/stop type data can be executed without generating an error.
