Title: Waste slurry disposal method and its device
Inventor: KATSUMATA NOBORU
IPC: B24B37/00
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To simply and quickly separate abrasive grains while the clogging of a filter is being prevented when abrasive grains are recovered out of waste slurry discharged from grinding and polishing operations. SOLUTION: A separation device main body 51 is partitioned by a filter part 52 so as to allow waste slurry to be fed with pressure to an upstream side space S1 by a pressure feed pump, an ultrasonic exciter 53 is turned on, concurrently when a downstream side space S2 is pressurized by a discharge pump P3, and particulates such as aqueous dispersion and shavings are circulated to the downstream side space S2 through the filter part 52. Abrasion grains are likely stuck on the filter part 52 by pressure feeding, however, they are shaken off because the filter part 52 is vibrated by ultrasonic waves. Therefore clogging is thereby prevented, and separation is quickly performed. And waste slurry containing abrasive grains remaining in the upstream side space S1 is extruded out into an abrasive grain discharging pipe, so that abrasive grains are thereby recovered.

Title: Manufacture of semiconductor device
Inventor: NISHIMURA HITOSHI
IPC: H01L21/306
Filed: 1989-03-24
Abstract: PURPOSE:To facilitate the unified formation of a cantilever structure and a stopper by removing the first semiconductor layer that is exposed from a window by electrochemical etching while impressing voltage to the second semiconductor layer as well as a semiconductor substrate. CONSTITUTION:The second semiconductor layer 3 is removed by etching from the window 42 of a mask film. When electrochemical etching is performed after causing the first semiconductor layer 2 to be exposed, both the second semiconductor layer 3 and a semiconductor substrate 1 are protected from electrochemical etching and only the first semiconductor layer 2 is removed because the second semiconductor layer 3 and the semiconductor substrate 1 each have a conductivity type that is opposite to that of the first semiconductor layer 2; besides, the above layer 3 and substrate 1 are impressed by voltage. As only the above layer 2 which is sandwiched between the layer 3 and the substrate 1 is in this way removed, etching goes crosswise and a cavity 21 is formed below the layer 3 and as a result, a cantilever structure made up by the second semiconductor layer 3 is formed. A stopper on the substrate side of a cantilever is easily formed to be integral with the cantilever.

Abstract: PURPOSE:To exactly measure the servo gain of a low frequency area by using an optical disk with prescribed eccentric quantity or surface oscillation quantity, as the signal source of a low frequency disturbance signal, and measuring a servo error signal and an actuator driving voltage. CONSTITUTION:Reflected beam from the disk with the prescribed eccentric quantity or surface oscillation quantity, is read by a photodiode 1. A tracking error signal to be outputted from an error amplifier 2 at that time and the actuator driving voltage, which is generated when an actuator 4 is driven by a phase correction driving amplifier 3 receiving this tracking error signal, are displayed and measured by a digital storage oscilloscope 14. Further, servo remainder (off-set quantity) and the displacement quantity of the actuator are calculated and it is calculated that how much the amplitude of low frequency noise (disturbance signal) is compressed up to the off-set quantity. Then, the servo gain of the low area is measured according to the result of this calcula tion.

Abstract: PURPOSE:To enhance the extent of paper feed accuracy by structuring a pair of holder pieces, being projectingly installed in a frame of a paper feed tractor, to produce a clamp force in a support shaft in close contact with it as far as the specified length along the axial direction. CONSTITUTION:When a clamper 9 is rotated from an unclamp state and a working internal circumferential surface in a smaller radial side being formed in this clamper 9 is made to run on that in a larger radial side formed in each holder piece 6a, these holder pieces 6a are slackened along the circumferential direction since they are projectingly installed as in a cantilever form along the circumferential direction, so that a free end part in the circumferential direction is largely slackened in the radial direction. With this constitution, a clamping inner circumferential surface being formed in each inner circumferential surface of these holder pieces 6a contacts close to the outer circumferential surface of a support shaft 11 with large pressure so that a clamp force is produced there, thus a paper feed tractor 1 is clamped to this support shaft 11.
