Title: Rough ball manufacturing device
Inventor: MIYATANI TAKASHI
IPC: B24B31/02
Filed: 1985-01-21
Abstract: PURPOSE:To enable manufacture of rough balls of ceramics with high efficiency by putting raw materials into a recess formed by surrounding a periphery of a grindstone disk with a cylindrical grindstone and pressing the raw materials against the cylindrical grindstone by rotating the grindstone disk at high speeds thereby abrading pointed corners of the raw materials. CONSTITUTION:Plurality of cubes 1 are loaded in a recess 9 to be placed on a grinding sand layer 4. While grinding fluid is introduced, a motor 17 is started and rotation of a shaft 18 is transmitted to a drive shaft 15 to turn a grinding machine 5 at speeds of 1,000rpm or higher. As a result, the cubes 1 on the grinding sand layer 4 are pressed against a side wall grinding sand layer 13 with centrifugal force and heaped on the peripheral part of the grinding machine 5 while being ground. Some of the cubes 1 in contact with the grinding sand layer 4 go round on the grinding sand layer 4 following the disk rotation and the pointed corners are rounded by abrasion. On the other hand, cubes 1 pressed against the grinding sand layer 13, while moving round following the disk rotation, are rounded with the grinding sand layer 13. Cubes 1 pressed against the grinding sand layer 13 stand still while being pushed up, drop by their own weights and rounded with the grinding sand layer 4 and again pressed against the grinding sand layer 13 with centrifugal force and finally rough balls are produced at a time with high efficiency.

Title: Manufacture of semiconductor device
Inventor: MIYOSHI YOSUKE
IPC: H01L29/205
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To avoid increase of the gate leak current due to the power feeding, breakdown voltage variation due to charge/discharge of charge traps in an SiN film, element characteristic-deterioration, including the drain current reduction, gate lugs due to the interface level at the interface of a protective film and semiconductor, and threshold voltage variation due to film stresses. SOLUTION: An SiN film 9 covering a semiconductor surface except the gate electrode 5, drain electrode 7, and source electrode 6, is formed by the catalytic CVD method which suppresses the increase of the gate leak current and gate lug due to plasma damage, as compared with the film forming by the plasma CVD method. This method also reduced the hydrogen concn. in the film 9, and hence suppresses the breakdown voltage variation. The stress in this film 9 is reduced about 1/10 the conventional SiN film, thus reducing the threshold voltage variation.

Title: Damping device
Inventor: SUZUKI TETSUO
IPC: F16F15/02
Filed: 1992-01-20
Abstract: PURPOSE:To restrict oscillation including high and low acceleration by reciprocating added mass by a driving means in accordance with signals from an oscillator displacement sensor, and releasing the transmission of driving force by a transmission switching means when the signal level is equal to or higher than specified. CONSTITUTION:The vertical oscillation of a floor 2 is detected by an acceleration sensor 9, and the oscillation of added mass 5 is detected by an acceleration sensor 10, so that the signal level in response to each acceleration is outputted. When the output level of the acceleration sensor 9 is less than specified, and the acceleration of the floor 2 is greater than the acceleration of the added mass 5, a servo motor 18 is rotated in the normal direction, so that the added mass 5 is moved upward via a speed reduction mechanism 19 and a ball screw mechanism 20. When acceleration is reverse in direction, the motor 18 is reversely rotated, so that the added mass is moved downward. Damping is therefore carried out actively in accordance with the magnitude of acceleration. When oscillation equal to or more than a specified level is propagated to the floor 2, switch-over to passive control is made by the releasing action of an electromagnetic clutch 8, so that the oscillation of the floor 2 is attenuated by the vertical movement of the added mass 5.
