Title: Magnetic optical type reproducing device
Inventor: ITO TAKAYASU
IPC: G11B11/10
Filed: 1986-11-14
Abstract: PURPOSE:To improve the extreme precise of a tracking control by converting the pattern of a recording track into a brightness and darkness pattern with using a magnetic optical effect, receiving the pattern in an image pickup device so as to convert it into an electric signal and discriminating data on a guard band and a recording track. CONSTITUTION:With irradiating light beams that can reproduce several recording tracks, a reflective light is detected, whereby the pattern of the recording track can be read. Namely, the reflective light is detected in the image pickup device 14 through a polarizer 10, whereby the electric signal with the pattern of the recording track can be obtained. The electric signal discriminates the recording track and the guard band, identifies the recording track to be reproduced, and counts a clock signal synchronizing with a scan start signal from the image pickup device 14 while discriminating the track pattern. Thus, the tracking control that can follow track warp and the like is attainable.

Abstract: PURPOSE:To make an electric motor unnecessary with a result of quiet operation and reduce the amount of a heat medium and make the constitution small by heating and evaporating a heat medium in a heat source vessel and condensating this vapor in a heating vessel with the latent heat of the heat medium transferred from the heat source to a radiator. CONSTITUTION:Hot water and steam is supplied to a heat transfer pipe 3 from a heating means 19 in the period from time t1-t2, and the pipe 3 is shut off in the period from time t2-t3. In a heat source vessel 1 a heat medium 2 is heated and evaporated by the hot water or steam passing through the heat transfer pipe 3 and the pressure in the heat source vessel 1 rises in the period from t1-t2 In a radiator 5 the steam of this heat medium is condensated and liquefied. The liquid level of the heat medium in the pump chamber 12 of a pump 11 is thereby raised. When it is detected by a detection element 16 that the liquid level has reached a predetermined liquid level l1, a heating means 17 heats the heat carrier in the pump chamber 12 by supplying hot water, etc. to a heat transfer pipe 18. With this arrangement, the pressure in the pump chamber 12 is raised and the heat carrier returns to the heat source vessel 1 via a pipe 14 from a discharge check valve 15.

IPC: B01F1/00
Filed: 1991-09-24
Abstract: PURPOSE: To provide a device for introducing oxygen from air as oxygen resource into a liquid, in which additional oxygen is added independent of airflow whereby the oxygen content obtained in the liquid is significantly higher than in the case that same amount of additional oxygen is combined with the feed air flow. CONSTITUTION: A liquid is kept in a mixing vessel 10 and a feed air is jetted in the form of bubble from an air jet point 13 into the liquid for dissolving oxygen in the liquid and/or reaction. An additional oxygen is jetted into the liquid independent of the feed air from additional oxygen jet point 19 isolated from surroundings of the air jet point 13 so as to minimize the mixture of the additional oxygen and the air bubble in the liquid. As a result, the content of oxygen in the liquid is significantly higher than the content of oxygen obtained when the same amount of oxygen is jetted into the liquid and combined with the feed air flow.

Title: Development processing method for master optical disk
Inventor: ARAKAWA YOSHIHIDE
IPC: G03F7/30
Filed: 1989-10-19
Abstract: PURPOSE:To allow defect-free development processing even if the surface of a photosensitive material is inadvertently stuck with small foreign matter and stains by moistening the surface of a material to be developed with sodium phosphate alone or a soln. mixed with the sodium phosphate and sodium silicate, then subjecting the photosensitive material to the development processing. CONSTITUTION:A master disk 1 subjected to cutting, exposing and recording is fixed to a turn table 2 and is rotated by a motor 3. The sodium phosphate alone or the soln. mixed with the sodium phosphate and the sodium silicate, which is a preprocessing liquid, is dropped from a nozzle 5 at the tip of an arm 4 from the outer peripheral part of the master disk 1 toward the central part; thereafter, the developing soln. is allowed to flow down from an arm 7 and a nozzle 8. The foreign matter and stains sticking to the master disk 1 are removed by the washing effect of the sodium phosphate and the sodium silicate in this way. The developing soln. is thus penetrated over the entire surface of the surface coated with the photosensitive material of the master disk 1 and the simultaneous development of the entire surface is executed.
