Inventor: TAMIYA KATSUTSUNE
IPC: B24B7/04
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To perform a uniform grinding of a glass substrate by keeping a specified amount of displacement of a grinding tool from the glass substrate. SOLUTION: Above a surface plate 7 rotatable around a first vertical axis 6, a grinding tool 16 for use in grinding a square glass substrate 5 rotatable around a second vertical axis 15 and set to the base disc 7 is provided. The grinding tool 16 can be reciprocated in a direction of diameter between a first grinding position (a) where a corner part 5a of the glass substrate 5 is set within a grinding range and a second grinding position (b) where it approaches more the first vertical axis 6 than the first grinding position (a) and a side part 5b of the glass substrate 5 is within a grinding range.  When the corner 5a passes over a moving path 32 of the grinding tool 16, the grinding tool 16 is moved up to the first grinding position (a) to grind the corner 5a and further when the side 5b passes over the moving path 32, the grinding tool 16 is moved up to the second grinding position (b) and the side 5b is ground. This operation is repeated.

Title: Centrifugal impact mill
Inventor: MURATA HIROYUKI
IPC: B02C13/14
Filed: 1989-03-10
Abstract: PURPOSE:To obtain a collision plate having prolonged service life by detachably fixing an ultrarigid member to the end part of the collision face part of the collision plate near to a rotor chamber. CONSTITUTION:Even when rock 4 thrown from a rotor chamber 3 is allowed to collide against a tip 8 provided to the end part of an anvil 6a near to the rotor chamber 3, the progressive state of abrasion of the tip 8 is made comparatively slow as shown in the horizontal cross sections a'-c' because the tip is made of cemented carbide. Thereby the collision angle theta of the rock 4 allowed to obliquely collide against the end part of the tip 8 is maintained as it is large. Therefor the collision face part 7a of the anvil base material 10 is abraded comparatively slowly and uniformly in a range over the whole surface. The service life is prolonged without causing local abrasion. Thereby frequency for replacing the parts is reduced.

IPC: G06F11/20
Filed: 1989-03-10
Abstract: PURPOSE:To prevent all the low-order agents from being set at inoperable states due to the defect of one low-order agent by connecting a hardware block to separate each low-order agent from a bus when a bus cutoff signal is set at every low-order agent. CONSTITUTION:The bus protection system is comprised of a high-order agent 1, the low-order agents 2-4, the bus 5, bus cutoff signal lines 6-8, and the hardware blocks 9-11. When a fault occurs in a first low-order agent 2 and malfunction occurs in a signal on the bus 5, the high-order agent 1 sets the bus cutoff signal on the bus cutoff signal line 6, and sets all the first hardware blocks 9 at disabled states, and separates the first low-order agent 2 from the bus 5 completely. Thereby, it is possible to surely separate a faulty low-order agent from the bus and to protect the bus even if the fault occurs in the low-order agent connected to the bus.

Abstract: PURPOSE:To prevent a magnetic disk from being deformed and damaged by providing a flange to support the inner circumferential part of the magnetic disk in a lower direction and a spring means to press the upper surface of the magnetic disk in a ring-shaped member to be overlapped in multiple steps and to be inserted to a spindle. CONSTITUTION:In a ring-shaped member 20 to be overlapped in the vertically multiple steps and to be inserted into a spindle 6, a flange 21 is provided to support the inner circumferential part of a magnetic disk 10 in the lower direction and a spring means 22 is provided to press the upper surface of the magnetic disk 10. Each magnetic disk 10 is clamped by pressing force, which is generated by the deflection of the spring part 22. However, the clamp force is made enough to be more than force to generate friction force resisting against force caused by a product between quantity for one magnetic disk and acceleration to be applied to this disk or product between inertia moment and angular acceleration. Since the ring-shaped member 20 is made enough thick, the deformation caused by the clamp force is reduced. Thus, the deformation of the magnetic disk and the damage of the glass disk can be prevented.
