Title: Method and device for detecting flaw of storage medium
Inventor: FUJITA SHO
IPC: G11B19/04
Filed: 1990-08-31
Abstract: PURPOSE:To surely detect the damage of a storage medium by inputting a readout voltage from a read head, and comparing the readout voltage with a preset voltage set in advance. CONSTITUTION:A rectifier circuit 12 inputs the output of a head amplifier 10, and rectifies it, and outputs it by making into DC. A comparator 14 inputs the output voltage of the rectifier circuit 12 and the preset voltage (c) from a voltage setting circuit 13, and compares them with each other, and outputs an abnormality signal ER1 by recognizing the fact that the output voltage from the rectifier circuit 12 goes less than the output voltage of the voltages setting circuit 13. Also, a differentiation circuit 15 inputs the output voltage of the rectifier circuit 12, and a comparator 17 outputs an abnormality signal ER2 by recognizing the fact that the output voltage from the differentiation circuit 15 goes over the output voltage of a voltage setting circuit 16. In such a way, it is possible to accurately detect the damage of the storage medium.

Title: Liquid supply apparatus for solid-liquid separator
Inventor: HATA KENJI
IPC: B04B1/02
Filed: 1989-09-05
Abstract: PURPOSE:To easily carry out clarifying operation by providing an oil supply vessel in the lower position than that of a bowl and forming a molecular pump structure in the seal part between a casing and the rotary bowl. CONSTITUTION:When the rotary bowl is revolved by the operation of a driving unit 8, higher atmospheric pressure is generated in the inner part. The pressurized air flows through a clarified liquid discharge opening 23 into a space part 23 where the pressure is raised. In the seal part between the rotary bowl 1 and the casing 7, a molecular pump structure is formed between a bent part 1A and a bent part 7A, and the air in the rotary bowl 1 is discharged into the space part 23 by the molecular pump effect. Thus, the pressure P1 in the space part 28 is raised and the pressure P3 in the vicinity of the opening of a liquid supply nozzle 10 is lowered. When this pressure difference is increased, the liquid to be treated flows out from the liquid supply nozzle 10, and is supplied into the rotary bowl 1. The solid component is stuck to the inner wall of trunk part of the rotary bowl 1 to be separated.

IPC: G01R29/12
Filed: 1983-12-05
Abstract: PURPOSE:To make it possible to reduce a measring error, by applying conductivity imparting or non-charging treatment to a charging part in the vicinity of a measuring part. CONSTITUTION:An internal shield 2 covers a measuring electrode 2 and a measuring circuit. Because an AC potential signal induced in the measuring electrode 3 is too minute as compared with the driving signal of the piezoelectric element 6 of a chopper part, an external electric field and noise can be suppressed by an external shield 1 but the influence of the driving signal of a piezoelectric vibrator upon a potential signal can not suppressed and the suppression of its influence is enabled by the internal shield 2. Further, each free end of the vibrator 5 becomes parallel to the measuring electrode 3 so as to be capable of shielding the electrode 3. Because the vibrator 5 is earthed and vibrated directly before the electrode 3, a total area for applying an electric field to electrode 3 from an object to be measured is varied and an AC signal having amplitude proportional to the measured and the electrode 3 at the same freuency as the vibration frequency of the vibrator 5 is induced in the electrode 3. In addition, in order to bring the end surface of a substrate to low impedance, through-hole treatment is applied.
