Patent JP-H05259030-A (JP)
Title: Position detector
IPC: H01L21/30
Filed: 1992-03-12
Abstract: PURPOSE:To facilitate the adjustment of the title position detector in a simple constitution by a method wherein the position of a pattern image re-focussed on a detecting surface is periodically oscillated in specific amplitude in the width direction of a photodetecting surface to be periodically detected according to the driving signals so that the detection signals reaching specific state when the pattern image is being oscillated centering on the photodetecting surface may be outputted. CONSTITUTION:When the exposed surface of a wafer 3 is beneath a focussing surface, a slit pattern image 16 is being oscillated at the end of the second auxiliary photodetecting surface 28c on the surface of a photoelectric conversion element 2. In such a state, a direction detecting signal S6 has a negative value while a position detecting signal S3 has zero value. Later, when the exposed surface of the wafer 3 is lifted passing the focussing surface of a projection optical system 2, the slit pattern image 16 intersects a photodetecting surface 28a in the R direction so that the position detecting signal S3 may be changed taking S curve shape by synchronous rectification (a). In such a constitution, the zero-cross point of this position detecting signal S3 is to indicate the coincidence position of the exposed surface with the focussing surface.

Title: Production of thin film magnetic head
Inventor: NATSUHARA YOSHINOBU
IPC: G11B5/255
Filed: 1984-04-30
Abstract: PURPOSE:To prevent flowing and foaming of an adhered melt and to obtain substantial adhesion strength by depositing a thin opaque film on the surface of an insulating protective film then polishing the surface of the thin opaque film to flatten the surface then adhering a protective plate thereto. CONSTITUTION:A metal 9 of Ti or Cu which is opaque and has particularly good light reflectivity is deposited to about 10mum equal to a rugged step S on the surface 8 of the insulating protective film 7 formed of a transparent material such as Al2O3 or SiO2 and having the step S. The surface is then subjected to lapping, polishing or abrasive grinding treatment to polish the surface to the extent that the metal 9 is chipped off, i.e., until the surface 8' of the film 7 is thoroughly flattened. The protective plate 10 such as crystallized glass is pressed and adhered finally to the surface 8' under heating to the extent that the surface 10' to be adhered melts. The surface 8' of the film 7 is thus thoroughly flattened and therefore the fluid condition is extremely good when the surface 10' of the plate 10 melts. Foaming is eliminated and ideal adhesion is executed.

IPC: B63H5/16
Filed: 1985-04-26
Abstract: PURPOSE:To mitigate the stress concentration at the fitting section of a structure and avoid the resonance of this structure by fixing part of the ring shaped structure to a stern section via support members and constituting the blade at the fitting sections of this structure thicker than the blade at other portions. CONSTITUTION:Part of the outer periphery 11a, 11b of a ring shaped structure 4 are fitted to a stern section 2 via support members 5. Fitting sections 13a, 13b of the structure 4 to a stern section 2 have the largest stress concentration, therefore, the blade thickness (d) is changed as shown in the figure so that its strength can thoroughly withstand. Accordingly, stress concentration is mitigated by increasing the blade thickness of the fitting sections 13a, 13b of the upper and lower sections of the structure 4 to the stern section 2. In addition, the inherent frequency is increased larger than in the past, and this can be made a resonance avoidance countermeasure.
