Title: Magnetic storage body and its manufacture
Inventor: YANAGISAWA MASAHIRO
IPC: G11B5/85
Filed: 1983-04-14
Abstract: PURPOSE:To obtain a servo system, in which high line density and high track density are realized without narrowing the data area, by covering a medium for data information having an easily magnetized axis oriented in one direction (circumferential or radial direction) in one plane, which is orthogonal to the medium for servo information, further on the medium for servo information by an oblique vapor-deposition device different in evaporating direction. CONSTITUTION:A vapor flow coming along the radial direction of a disk 9 from an incident direction 10 at an incident angle theta (theta=10 deg.-60 deg.) attaches the hatched part 13 of the disk 9 after the flow is narrowed by a slit 7. Since the easily magnetized axis of this attached substance is oriented in the direction parallel to the incident direction, the easily magnetized axis is oriented along the radial direction of the disk 9. Another medium for data information 4 formed on the medium 3 has its easily magnetized direction normal to that of the medium 3 in the same plane. However, in the course of manufacturing the said medium 4, the rotating axis of the disk 9 is shifted, since the incident direction of the vapor of an oblique vapor-deposition method is changed to the circumferential direction of the disk 9. Since the easily magnetized axis of the medium 4 is aligned in parallel to the incident direction, so the axis is aligned easily in the circumferential direction of the disk 9.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To suppress vibration even in either mode of CAV or CLV by movably sealing plural ball bearings in the angular direction around a rotary shaft in a cavity and changing positions according to the mode. SOLUTION: Four to eight pieces of iron ball bearings 31 are arranged in the circular cavity 33 on an upper surface of a rotary base 17 of a drive unit 11 to be sealed with a plate 35. For the CLV mode, electromagnetic coils 41 of the same number as the ball bearings 31 are arranged symmetrically on the bottom surface of the rotary base 17 to be power supplied through contact brushes 47, 49. In the CAV mode, the electromagnetic coils 41 are separated, and the ball bearings 31 are arranged naturally in the cavity 33 so as to freely move around the shaft 23 and to balance a disk 13.  In the CLV mode, since a speed of a motor 15 is changed always, the electromagnetic coils 41 are power supplied, and respective coils attract respectively a piece of ball bearing 31 by an electromagnetic field to stop and 'freeze' them on the balanced positions, and the matter that the rotation of the motor 15 is disturbed while the speed is changing is eliminated, and the vibration is suppressed minimally.

IPC: H03K5/00
Filed: 1989-03-18
Abstract: PURPOSE:To prevent a change in the duty before and after modifying a frequency and to set the frequency optionally by providing a 1st counter and 2nd and 3rd counters counting the output pulse of the 1st counter. CONSTITUTION:A frequency counter 5 outputs a pulse (a) every time the counter counts for a period corresponding to a frequency division ratio N of the frequency of the output pulse and an M-adic counter 6 outputs a pulse (c) every time M sets of the pulse (a) are counted. An AND gate 9 is opened by raising an output (d) of a FF 8 with the pulse (c) and a duty counter 7 generates an output (f) when the counter 7 counts the pulse (a) by the duty (n) and the FF 8 is reset to output a pulse (d) whose duty is n/M. Thus, a quantity proportional to the pulse frequency is set by the frequency division ratio N and the duty is set freely by the value (n) and the duty is kept constant in the case of modification of the frequency.

Title: Solar energy collector
Inventor: SUGIURA MASARU
IPC: F24S23/70
Filed: 1982-04-21
Abstract: PURPOSE:To provide the titled collector having high heat collecting efficiency in a comparatively simple construction by forming a heat collecting plate in a cross-shape in section. CONSTITUTION:A cross-shaped plate 6 is formed by an aluminum plate which is bent and worked so that its section is formed by four curved parts 7, and both end parts 8 are connected to each other by caulking or the like. Therefore, parts encircled by four curved parts become excellent clamping parts into which an inner pipe 2 is inserted, and the heat collecting part can be constructed extremely simply. Further, according to this heat collecting plate 6, four junctions with the inner pipe 2 indicated by arrow C are heat transfer parts from the heat collecting plate to the inner pipe. Therefore, the heat transfer property is remarkably improved. Furthermore, since the fin parts 9 of the heat collecting plate interrupts incident light (d) which has heretofore escaped to the outside, the incident light (d) radiated by the collector is collected at the heat collecting part without loss. Further, the width of the heat collecting part 6 is selected to be slightly shorter than the inner diameter of the outer pipe by taking into consideration of the damage of the outer pipe 1 due to thermal expansion.

Abstract: PURPOSE: To improve the apparent S/N ratio of an audio amplifier with ease by comparing a higher reference voltage than a noise voltage with an input so that a switch is turned off, when there is no input, thereby to effect the auto-muting operation.  
     CONSTITUTION: The output of an audio amplifier, which is amplified by an amplifier 11 and a both wave rectifying circuit 12 and which is then converted in a DC voltage according to the level, is compared by a comparator 14 with a higher reference voltage than the maximum noise level which is set by a comparison level voltage generating circuit 13. By a pulse detecting circuit 15 which is composed of an AND circuit and an integrating circuit to be reset with the compared output of the comparator 14, whether the audio amplifier has an input or not is detected. With no input, an analog switch is turned off through the detector 15. Then, the output of the audio amplifier is not generated at a terminal 17, and the auto-muting operation is carried out without any manual operation so that the noises of the audio amplifier during no input are transmitted. Thus, the apparent S/N ratio through the feeling can be easily improved.
