Patent JP-H02202389-A (JP)
Title: Motor controller
Inventor: KOBAYASHI MASAO
IPC: H02P29/00
Filed: 1989-01-28
Abstract: PURPOSE:To detect abnormal condition of motor quickly by providing a motor drive means, a rotation speed detecting means, and a drive pulse operating means, while furthermore providing a means for comparing a reference duty with the duty of drive pulse in order to judge an abnormal condition. CONSTITUTION:A motor 60 is driven by the output from a drive circuit 62 while the rotary speed is detected through an encoder 63 and a drive pulse is calculated at an operating section 72 based on the difference between the detected rotation speed and a target rotary speed of the motor 60. The drive pulse is decremented or incremented according to whether the detected rotation speed is higher or lower than the target value, then the incremented or decremented drive pulse is fed to a drive circuit 62. Duty of the drive pulse is compared with a reference duty at a judging section 73, and judgement of abnormality is made when the duty of the drive pulse exceeds over the reference duty.

Title: Laser beam recordor
Inventor: YAMASHITA YUJI
IPC: B41J2/44
Filed: 1990-01-31
Abstract: PURPOSE:To easily vary a spot diameter by varying the incident angle when a photosensitive body is irradiated by a laser beam in a sub scanning direction in a state where the optical distance between a deflecting means and the photosensitive body is kept almost constant according to scanning line density. CONSTITUTION:First and second mirrors 16 and 17 have their positions or angles varied by a mirror position variation part according to the scanning density selected by a scanning line density selection part. The mirror 16 is rotated in the same position with a refletion point P as the center. The mirror 17 whose focal points are each of an irradiation point 21 and the refletion point P is moved over an oval surface, and the reflective surface of the mirror 17 is adjusted to an angle which matches the tangent of the oval. When the surface of the photosensitive body drum 19 is irradiated by the laser beam 12 from a vertical direction, the size of a spot in the sub scanning direction becomes d, and when the surface is irradiated at an angle alpha the size of the spot D becomes D=d/cos alpha. That is, by varying the incident angle to the drum 19 of the beam 12, the necessary size of spot of the laser beam can be obtained.

Filed: 1992-02-04
Abstract: PURPOSE:To improve the access performance of a CPU while stably keeping it by storing data to be accessed by the CPU in the cache memory of any optimum device corresponding to the access conditions. CONSTITUTION:Based on the condition of access from CPUs 101-103 to relevant data, a disk controller 201 judges to which cache memory of the device among cache memories 107-109 of channel devices 104-106, cache memory 202 of the disk controller 201 and cache memories 304-306 of disk drive devices 301-303, the data accessed from the CPUs 101-103 is to be stored and control is executed so as to store the data in the cache memory of the device judge as the storage destination. Therefore, since the data are always stored in the optimum cache memory, cache data can be managed with a little uselessness, and the access performance of the CPUs 101-103 can be improved while stably keeping it.

Title: Magnetic recording medium
Inventor: MIYAKE AKIRA
IPC: C09D5/23
Filed: 1983-02-07
Abstract: PURPOSE:To eliminate a slump of frequency characteristics and to improve the sensitivity with reduction of noises by forming a lower magnetic layer containing metallic magnetic powder with the coercive force set within a specific range and an upper magnetic layer containing iron nitride magnetic powder with the coercive force set equal to or higher than that of the lower layer on a supporter. CONSTITUTION:The 1st magnetic layer containing the metallic magnetic powder having 600-1,300 Oe coercive force is formed on a supporter of a polyester film, etc. Then the 2nd magnetic layer containing the iron nitride magnetic powder having the coercive force set equal to or higher than the 1st layer is formed on the 1st magnetic layer. The ratio of thickness is preferably set within a (1:1)- (1:10) range between both magnetic layers. The characteristics of a low-frequency band are not improved if the upper magnetic layer is too much thicker than the lower layer, while the characteristics of a high-frequency band are not satisfactory if the upper layer is too much thinner than the lower layer with unsatisfactory reduction of noises. In such a way, the excellent characteristics can be secured over a wide range of frequencies for a magnetic recording medium.

Title: Corrugated leaf spring type vibration damper
Inventor: SASAKI SHIYOUJI
IPC: F16L3/202
Filed: 1981-02-12
Abstract: PURPOSE:Not to restrain the slow displacement caused by thermal change or the like, and to damp the sudden vibration caused by an earthquake or others. CONSTITUTION:When a pipe is suddenly vibrated by an earthquake or the like, a main link 4 is also suddenly turned forward and backward. However, a coil spring 7 is pushed by the inertia of shoes 5 to deform a square 9, 10, 11, and 12 into a rhombus, and a corrugated leaf spring 13 is pushed by one end of each shoe. At this stage, a component force to turn the corrugated leaf spring of shoes circumferentially is also given. But since the corrugated leaf spring is pushed in to expand, the force to turn this spring is greatly braked by the frictional resistance spread in the whole circumference of the corrugated leaf spring.
