Filed: 1990-10-30
Abstract: PURPOSE:To make the inside of a bath room comfortable and healthy space by jetting ozone into the bath room through a three-way valve at a jet port facing the inside of the bath room. CONSTITUTION:Oxygen enriched air AO obtained by passing air A outside a bath room 12 through an oxygen enriching device 11 is supplied to an ozone generator 7 to generate ozone O. To purify the inside of the bath room 12 by sterilization, the ozone O is jetted out at a jet port 14 provided on a wall surface of the bath room through a three-way valve 13. When the ozone generator 7 is stopped, the oxygen enriched air AO alone is generated and hence, likewise, when the ozone is jetted into the bath room 12 at the jet port 14 in the bath room 12, a comfortable bath room space is formed. Hot water 2 in a bath tub 1 is sucked through a suction port 4 including a filter for removing foreign matters with the driving of a circulation pump 5 and then, circulated through a circulation pipe 16. Moreover, the ozone O from the three-way valve 13 and a check valve 17 is injected by an ozone dissolving device 6 and then, separated by a gas/liquid separator 8. A circulation water 15 into which the ozone O is injected is purified and sterilized by the decomposition of microorganisms and organic substances therein by oxidation by the time it returns to a water discharge port 18 of the bath tub 1.

Title: Focus detecting device for optical head
Inventor: TAKETOMI YOSHINAO
IPC: G11B7/09
Filed: 1986-12-10
Abstract: PURPOSE:To eliminate the track crossing interference without deteriorating the detecting sensitivity for a focus error by setting a cut-off means into a luminous flux to cut off a part or the whole of an area. CONSTITUTION:A cut-off means 24A is set into a luminous flux 10A. Thus the asymmetrical properties of a tracking signal which is included in a detected light spot are canceled. In other words, the flux 10A that passed a part of an area, especially a part where the spherical aberration of a condenser lens 14A is large is cut off by the means 24A. Thus the asymmetrical properties of a detected light spot can be corrected and the influence of the track crossing interference. When the area is entirely cut off, no influence of the track crossing interference is confirmed since the remaining luminous flux contains no tracking signal.
