Title: Housing case for electric apparatus
Inventor: SAKAI TOSHIO
IPC: H05K5/02
Filed: 1994-07-07
Abstract: PURPOSE:To improve the finishing yield and yet the rigidity of a housing case of synthetic resin for scanner units. CONSTITUTION:The first wide support 30a' in a synthetic resin housing case 30 is to support the bottom of an ftheta lens 21, and the second wide support 30d is to support the bottom of the driving motor 31 in a rotary polygon mirror 27. The first wide support 30a' and the second wide support 30d are formed at an appropriate distance. A first connection 30e and a second connection 30f the height of which is between those of both the supports, are formed between the supports 30a', 30d. In molding a housing case 30 by injection, fluid synthetic resin flows from the first support 30a' that has the wide surface almost in the horizontal direction to the second support 30d that is largely different the first support 30a' in height. The first and second connections 30e, 30f, mentioned above, smooth the flow of the synthetic resin, which eliminates the occurrence of chipped resin and thus improves the yield of products. In addition the perpendicular portions of the connections function as reinforcing ribs.

Title: Optical information recording medium
Inventor: INOUE KAZUO
IPC: G11B7/24
Filed: 1989-06-19
Abstract: PURPOSE:To greatly increase the number of repetitions of recording and erasing by specifying the respective heat capacities of the recording layer of the optical information recording medium of a phase change type and protective layers formed on the top and bottom thereof. CONSTITUTION:The 1st protective layer 2, the recording layer 3 and the 2nd protective layer 4 are successively laminated on a substrate 1 and are stuck to a protective film 7 via an adhesive agent 6. The heat capacities per unit area of the recording layer 3, the 1st protective layer 2 and the 2nd protective layer 4, respectively designated as Ma, Md1, Md2, are so set that the following relation holds: Ma<Md1/3, Ma<Md2/3. The heat capacity of the recording layer is small in such a manner and the structure in which heat escapes rapidly from the protective layers is adopted; therefore, the protective layers do not heat up to a high temp. Since the generation of pinholes is thereby suppressed, the number of the repetitions of the recording and erasing is greatly increased.
