Title: Magnetic recording and reproducing device
Inventor: OTSUKI SHINSUKE
IPC: G11B15/467
Filed: 1990-04-17
Abstract: PURPOSE:To obtain highly accurate tracking operation by using a reproduced output outputted from either one of two specific magnetic heads for controlling the position of the other magnetic head against recording tracks. CONSTITUTION:The 1st magnetic heads 1a, 1b to be used for a normal time mode and the 2nd magnetic heads 2a, 2b having one over odd number of the track width of the 1st magnetic heads 1a, 1b and having the same azimuth angle as the 1st heads 1a, 1b are arranged so that the a half of the track width of the 2nd heads 2a, 2b is superposed to the other half. A tracking control means 8 uses a reproduced output outputted from one of the two magnetic head groups, i.e. the 1st magnetic heads 1a, 1b and the 2nd magnetic heads 2a, 2b for controlling the position of the other magnetic head groups against recording tracks. Since the other magnetic head group which is not used for reproducing signals can be used for detecting the tracking shear of the reproducing magnetic head group, highly accurate tracking operation can be obtained without increasing the production cost of the magnetic recording and reproducing device.

Abstract: PROBLEM TO BE SOLVED: To mix gas such as ozone into liquid such as bath water by negative pressure of an ejector by arranging the ejector in a position higher than the surface of the liquid in a liquid storage tank. SOLUTION: A device main body 5 is communicated with an ozonizer 10 through a prefilter 7 positioned upstream of a circulating pump 6 for drawing bath water from a bathtub 1 to circulate it and for filtering the bath water, a water purifying tank 8 positioned downstream of the pump 6 and for removing organic matter and other pollutants in the bath water by adsorption, decomposition, filtration, or the like, and a heating tank 9 for heating the circulated bath water or keep its temperature temperature.  Since an ejector 11 for sucking ozone into a circulating flow passage by negative pressure to perform bacteria control or sterilization is arranged inside the device body 5, the negative pressure at the ejector 11 is almost fixed by the installing position of the device body 5 relative to on being fill of the bath water, it is unaffected by the installing position of a water feed/drain unit 2.

Title: Charged particle beam device
Inventor: OKUNUKI MASAHIKO
IPC: H01L21/66
Filed: 1987-04-28
Abstract: PURPOSE:To eliminate the generation of heat and the interference between adjacent electron beams and to simply execute a positioning operation by using plural marks by a method wherein charged beams are emitted according to a time series from more than two out of plural changed beam generation sources and each charged beam or its secondary electron or a reflected electron is detected. CONSTITUTION:Out of prealignment marks M1, M2, M7, M8 formed on a wafer WF, a position of, e.g., the mark M1 is read out by a sensor S1; the position of the mark M2 is read out by another sensor; on the basis of this read-out operation, an initial positioning operation of a head MB is executed by using piezoelectric elements Px, Py, Ptheta. When the marks are detected in these cases while an EB is radiated, e.g., from an EB source ES0 toward the mark M7 at different stages, a secondary electron or a reflected electron is generated from the wafer WF. When this electron is received by a sensor formed collectively on the side of a substrate MB, e.g. by a P/N junction, it is possible to execute the positioning operation by a single signal processing means without an influence by the interference between charged beams, and an alignment operation can be executed without installing a special light source and its detection means.
