Title: Magnetic disk device
Inventor: ISHIDA MICHIO
IPC: G11B25/04
Filed: 1989-12-15
Abstract: PURPOSE:To clean the magnetic disk surfaces by providing a dust sucking mechanism having plural openings opposite to the disk surfaces in a position between adjacent disks and forcibly exhausting the dust through these openings. CONSTITUTION:When the rotation of the magnetic disk 5 is raised, the pressure at a remote part from a spindle 1 is increased, while the pressure in the centripetal direction is decreased. Consequently, an airflow generated from protrusions of a spindle hub 2 and the disks 5 is circulated in the device to enter a gap of the low pressure hub and then to pass through a filter 13, so that a clean air-flow is supplied to the disks 5 and magnetic heads 6. Even when a dust amt. is increased and the dust should intrude into a minute gap between the disk 5 and the head 6, since the dust is forcibly sucked by the sucking mechanism 14 having plural openings through a pipe 16 with an exhausting mechanism, there is no infiltration of the dust into the minute gap between the disk 5 and the head 6 and the clean airflow is always supplied.

Title: Inverter
Inventor: HASEGAWA MASAYASU
IPC: H02M7/48
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To obtain an inverter in which unnecessary starting is prevented by a constitution wherein the starting conditions are excludes at least partially when a predetermined input signal is inputted. SOLUTION: At the time of abnormality, a reset signal is read in (Step 11), presence of reset signal is determined (Step 12), and the process is continued as it is when the reset signal is not present. When a reset signal is inputted, a decision is made whether a start signal is turned on (Step 14) and the process is continued as it is when it is turned on. The abnormality is released when the start signal is turned off (Step 13). When the start signal is provided, the reset operation is rejected even if the reset signal is inputted and the operation is not started immediately after the provision of reset signal. Consequently, unnecessary operations due to inadvertent provision of reset can be prevented after releasing the abnormality.
