Filed: 1985-08-20
Abstract: PURPOSE:To make is possible to continuously measure the recirculation ratio of lubricant, by irradiating the refrigerant having lubricant dissolved therein recirculating through a refrigerant circuit with ultraviolet rays having a wavelength permitting the absorption of lubricant only and measuring the attenuation quantity of transmitted light for said incident rays. CONSTITUTION:The refrigerant compressed by a compressor 1 is liquefied by a condenser 2 to pass through an expansion valve 3 and evaporated in an evaporator 4 to be returned to the compressor 1. At this time, an optical window 6 transparent to ultraviolet rays is provided on the part of piping 5 and a light source 7 is arranged to one side of said window 6 and a light receiving unit 8 is arranged to the other side thereof. The light emitted from the light source is absorbed by the lubricant in the refrigerant when passing through the piping 5 and the energy thereof is attenuated according to the Lambert/Beer law. Therefore, from the result of the relation between absorbance and an oil recirculation ratio preliminarily measured by using the refrigerant (Freon) and lubricant (naphthenic type), the oil recirculation ratio can be measured.

Title: Magnetic disk device
Inventor: KAWANO MASAFUMI
IPC: G11B33/14
Filed: 1990-07-11
Abstract: PURPOSE:To prevent the deviation and the distortion of a rotation driving part to improve the reliability by controlling the power source of a cooling fan in accordance with the temperature of a head disk assembly detected by a temperature detecting means at the time of receiving and decoding the power- on/off instruction from a higher-order device. CONSTITUTION:An instruction decoder 9 receives and decodes the power-off instruction from a higher-order device 1 to issue a power-off command to a power control circuit 2. This circuit 2 receives this command to immediately turn off the power source of an electronic circuit 3. The temperature of the head disk assembly HDA measured by a temperature measurer 5 and a reference temperature value 6 are compared with each other by a comparator 7, and when the value 6 is higher, the circuit 2 is operated by a thermo signal 8 to turn off the power source of a fan 4 for HDA. When the value 6 is lower, the circuit 2 keeps the power source of the fan 4 turned on by the signal 8, and the HDA is cooled till its temperature is lower than the value 6. Thus, the deviation and the distortion of the rotation driving part of a magnetic head positioning device or a magnetic disk are prevented to improve the reliability.

Title: Substrate treating device
Inventor: KIZAKI KOJI
IPC: B01J19/12
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To reduce the damage due to ultraviolet rays of an illuminometer for controlling a lamp by positioning the ultraviolet ray illuminometer within a region where ultraviolet rays arrive in a substrate box when measuring illuminance and retreating the ultraviolet ray illuminometer outside the region where ultraviolet rays arrive when no illuminometer is used. SOLUTION: An ultraviolet ray illuminometer elevating mechanism 21 is driven when starting the treatment of a substrate and an ultraviolet ray illuminometer 15 is raised to position itself in a region where ultraviolet rays arrive. Then, when a certain amount of time passes, an illuminance detection part 16 calculates the putting-out timing of a dielectric barrier discharge lamp 9 to apply a specific amount of ultraviolet rays to a substrate 3 and gives the result to a control part 17. When the illuminance changes, the putting-out timing of the lamp 9 is obtained, based on the illuminance change and the signal is given to the control part 17.  An illuminometer measurement timing control device 22 drives the ultraviolet ray illuminometer elevating mechanism 21 accordingly and lowers the ultraviolet ray illuminometer 15, thus retracting it to the lower side from the lower edge of the region where ultraviolet rays arrive.
