Abstract: PURPOSE:To obtain a photosensitive compsn. having a tough photosensitive film and developable in an aq. developing soln., by using a specified polymer, such as polyvinylbutyral, and specified amts. of org. solvent and azide compd. CONSTITUTION:10pts.wt. polyvinylbutyral having 10,000-230,000 average mol.wt. and 20-80mol% butyralized degree, 2pts.wt. azide compd., such as 4,4'-diazidochalcone, 120pts.wt. solvent mixture, contg. MEK as an essential component, and a small amt. of oil blue, etc. are mixed to prepare a photosensitive soln. A polyethylene terephthalate film subjected to corona discharge treatment is coated with said photosensitive soln. to about 3mum thickness and dried to obtain a photosensitive film. This film is exposed to a mercury lamp by bringing a negative original into contact with it and developing it with an aq. soln. of sodium salicylate. As a result, the obtained photosensitive film is not only tough but also advantageous in the following points: The obtained relief is sharp superior in image quality, and it is obtained with good workability because no org. solvent is used in the developing soln.

Abstract: PURPOSE:To prevent the decrease in lot-number reading accuracy due to noise by etching the surface of a semiconductor wafer, forming a lot-number pattern on a printing area, forming a metal film on the entire surface, and selectively removing the unnecessary part of the metal film on a circuit area and the metal film on the printing area at the same time. CONSTITUTION:A printing area 12 and a circuit area 13 are set on a semiconductor wafer 11. The surface of the printing area is etched, and a lot-number pattern 14 is printed. Then, an insulating film 15, a metal film such as Al and a resist film 17 are sequentially formed on the entire surface. The unnecessary part of the metal film 16 in the circuit area 13 and the resist 17 on the printing area 12 are exposed, developed and removed. Then, with the resist 17 as a mask, the metal film 16 is etched. The metal film 16 at the unnecessary part of the circuit area 13 and on the printing area 12 is selectively removed. The remaining resist 17 is further removed. Then, the same process is repeated, and the circuit pattern is completed. The metal film is not accumulated on the printing area, and mixing of the noise component caused by foreign matter into read-out signals is prevented.

Filed: 1985-07-05
Abstract: PURPOSE:To improve the durability of the sliding surface of a supporting member by exposing only the fractional part including at least a magnetic gap to the sliding surface so that the part of the core to be housed in the support member is stably and securely held. CONSTITUTION:A peak part 10 of a magnetic head core 1 is fitted into a core slot 15 of the support member 12. A shoulder part 11 of the core 1 is so set at l1 l2 and theta1 theta2 as to be matched to a core supporting part 16 of the member 12 to permit the easy mounting and positioning of the core 1 to the member 12. The width of the core at which the core 1 rubs against a recording medium is considerably decreased to l1 with respect to the overall length l3 of the core 1 by which the area occupied by the core in the sliding surface 3 is minimized. The wear of the sliding surface 13 is thereby decreased and the durability thereof is improved. The areas of the core 1 except the part to be exposed to the surface 13 are housed in the member 12 in the shape matched to the shape of the core and therefore, the core 1 is stably and securely supported.

Title: Production of flaky glass
Inventor: SATO NORIAKI
IPC: C03B37/005
Filed: 1991-06-20
Abstract: PURPOSE:To stably produce a thin flaky glass having <=5mum average thickness without any variance in thickness. CONSTITUTION:A molten glass material 1 is blown into a hollow thin film 6 by a blowing gas, and the thin film 6 is crushed 7 to produce a flaky glass 8. In this case, SO3 is mixed into the blowing gas to increase the SO3 content in the blowing gas in contact with the film 6. Since the SO3 is increased, the surface tension of the glass material is decreased, and the plasticity of the film 6 is maintained. Accordingly, the variance in thickness of the film 6 is prevented, the film is not broken, and the thin flaky glass 8 uniform in thickness is stably produced.
