Patent JP-S61202348-A (JP)
Title: Optical information recording member
Inventor: ONO EIJI
IPC: G11B7/24
Filed: 1985-03-06
Abstract: PURPOSE:To prevent the deterioration in signal quality when recording and erasion are repeated by using the different structure of protecting layers at both sides of a thin film recording layer or the different materials for structure between the light incident side and its opposite side. CONSTITUTION:The protecting layers 2 and 4 have different materials or different structures. When laser light is supplied from the side of the layer 2, the larger value of heat escapes toward the layer 2 from thin film recording a layer 3 than the route toward the layer 4 from the layer 3. The difference in temperature is reduced in the thickness direction of the layer 3 and at the same time an excessive rise of temperature is suppressed at the areas close to the interface between the layer 2 at the light incident side and the layer 3. The heat is rather liable to escape to both layers 2 and 4 from the layer 3 and then to stay at the opposite side. Therefore, the difference in temperature is reduced between the light incident side and its opposite side in the thickness direction of the layer 3. Thus the irradiated part reaches entirely a sufficient level of temperature. Thus it is possible to increase the repeating frequency of recording and erasion with no deterioration in signal quality.

Title: Projection optical device, aberration measuring method, projection method, and manufacture of device
Inventor: IMAI YUJI
IPC: G01M11/02
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To enable measurement of various aberration of a projection optical system with a higher precision. SOLUTION: As a mark plate FM having a first mark and a second mark formed thereon is illuminated by a measurement illumination light IL' from a measurement illumination system (36, 32, 34), the measurement illumination light IL' passes through the mark plate FM and forms optical images, that is, enlarged images of the first mark and the second mark, on the lower side of a reticle R via a reduction projection optical system PL. The enlarged images of the first mark and the second mark are detected by photoeletectors 12A and 12B, and the positional relation between the image of the first mark and the image of the second mark, and the aberration of the projection optical system PL based on the positional relation, are found by a processing unit 16 on the basis of the result of detection by the photodetectors.  In this case, since the aberration of the projection optical system PL is found using the positional relation of the enlarged images, it is possible to measure the aberration of the projection optical system PL obviously at a higher precision than in the case where the aberration is based on the positional relation of reduced images.

Abstract: PURPOSE:To perform precise controls by a method wherein in the case a comple tion time is reserved, the heating time period of washing water and the drying time period are calculated based on the results of volume sensing and the opera tion start-up time is determined by adding the calculated result to the operation time period to be determined under the conditions set at the beginning. CONSTITUTION:At step S11, a volume sensing is performed in a state no water is in a water tank before water supply, and at step 12, it is confirmed whether completion time is reserved. When completion time is reserved, it is judged whether an operating course requiring a period of time, which is set based on the supply water temperature, the ambient temperature and operating conditions that have been obtained from the previous operation, is completed before the time reserved at step S13. When there is no problem with the reservation time, an allowance time period is added to the required time period obtained to determine the operation start-up time at step S17. When the operation start-up time comes. water is supplied at step S19, and the operation proceeds to washing and rinsing steps. At step 20, memories are updated according to the water temperature data detected at this time of water supply.
